pipeline ball valve-reduced bore High-performance

Product Description of High-performance pipeline ball valve-reduced bore:

 High-performance pipeline ball valve is Raymond(RMD)hightech products,as switch control equipment,it is mainly used in natural gas,oil,gas,liquefied natural gas pipeline transmission system and other industries,its anti-sulfur products containing hydrogen sulphide,impurities and high corrosion are suitable for the long-distance natural gas pipeline.

Design Features of High-performance pipeline ball valve-reduced bore:

Body of high-performance pipeline ball valve is forged structure.The connection type for body and vice-body can be BB(bolted connection)and WB(welded connection).The WB(welded connection)and the LWB(Fully-welded extended stem)structure isadopted for buried ball valves,as shown below.
High performance pipeline ball valve series has the feature of strength, high perfect sealing, maintenance-free, long life and so on. The production of this series ball valve adopts the international advanced ball valve design and manufacturing technology, selects high-quality materials in accordance with the standard selection of materials and combines with advanced materials forming forging technology. At the same time, with the years of ball valve design and manufacturing experience, the use of advanced processing and manufacturing equipment and production and processing technology, through the first-class inspection and testing equipment and instruments, perfect quality assurance management system and excellence in the production of high-performance philosophy can ensure the quality of valves. This series of valve has the performance of a high strength, defect-free forging body, excellent sealing performance, even at maximum pressure difference(full pressure),it will still be able to ensure that seal without leakage, after frequent switching action to realize a safe usage in the transportation of oil, natural gas, coal gas, and other special medium transportation pipeline.

The special structure of valve seat seal of High-performance pipeline ball valve-reduced bore:

Floating structure means seat reciprocally can move along channel direction,so as to guarantee the ball and seat are tightly sealed.
(
)Valve seat structure suitable for different occasions and sealing requirements
Valve seat can be designed as a standard single-piston effect and specific dual piston effect,Figure1 shows single-piston effect-inletside seal;Figure2 shows Dual Piston effect-outlet-side seal;Figure3 shows special dual piston effect sealing structure
(
)Multi-level structure of the valve seat seal
As shown in Figure4,there are two elastic O-ring in the valve seat ring-ring A and ring B.Sealing ring A spring-loaded through the valve seat so that the sealing surface of sealing ring A tightly fit with ball surface to form an initial seal.When there is pressure in the system medium,the piston force
produced by the piston force produced by the piston effect of size difference makes elastic deformation of the ring A Ershi sealing surface and ball more closely fit the surface to form a re-sealing;meanwhile,due to ring A in the medium resulted in elastic deformation under pressure so that the sealing ring B is also closely fit the surface of ball for the formation of the second stage seal.When the system medium pressure increasing,it will have an enormous pressure in the valve seat ring A and ring B,so that the two seals have a greater elastic deformation,and then the metal valve seat ring surface and the ball surface sealing together to form a third level of metal to metal seal.
(
)The assisted valve seat sealing equipment
Based on the actual service condition,medium requirement,sealing requirement,etc.,the assisted valve sealing equipment will be considered to be necessary or not.The assisted valve sealing equipment is a one-way valve installed outside of valve body that can prevent medium leakage and can inject sealing grease into valve body by external force.When the assisted valve seat sealing equipment is required,valve seat ring shall be design and processed with injection grove and hole to connect the assisted valve seat sealing equipments.Such equipment can prevent the medium by the sealing of injection of rease.Refer to Figure5 for reference.

Unique and safe seat structures of High-performance pipeline ball valve-reduced bore:

Ball valve fireproof design is implementation of the API607,API6FA standards.According to service conditions and user requirements,ball valve can be designed as a fireproof structure.
(
)Fireproof structure of seat
As shown in figure7,there is composite fireproof ring,which are combined with graphite and stainless steel wire in the seat.Once the soft ring is burnt out in case of a fire,the fireproof ring and seat ring will form a piston structure through the spring to load the valve body.That will push and closely contact the metal seal surface of the seat ring to the body surface,So as to prevent a lot of medium from leaking from the burnt place of the seat ring,and prevent the fire from expending.

()Fireproof structure(body and bonnet)
The seal gasket for bolt connecting valve body and valve bonnet,are used fireproof stainless steel wire and flexible graphite gaskets.Gasket compression load through the bolts and ultimately,ensure the valve body and valve cover between the metal to metal contact,so that the valve can with stand more high load,but also improve the fire safety of the valve.But for the full welded ball valve,the valve body and cover is welded structure,that fundamentally eliminate the possibillity of leakage of the valve housing.Even in the case of fire damage,there will be no leak.
(
)Fireproof structure(body/packing and stem)
The body and packing connection gasket adopts fireproof stainless steel wire and flexible graphite gaskets.The stem packing adopts flexible graphite to ensure no leakage in case of fire.

Q: I've been playing french horn in school for about five years, and I'm not exceptional by any means! But I love the instrument. Our school district bought a french horn a few years ago when we didn't have enough french horns for players. The almost new Holton has great tone. But unfortunately it fell into ignorant hands and has been neglected for two years. I just received the instrument and cleaned it up and got it back up to snuff, except for the valves. I can't get them to run smoothly!! They act all gummed up. I've put oil in the top and bottom of the valve, and I've dropped a couple drops in the tubes down onto the valves, but they're still gummed up! Do I need to use more oil?? Or what? Any suggestions?
Here are 3 options I know of - 1) take it in and have it cleaned. This can cost anywhere upwards from $40. I paid $75 last time. 2) Clean it yourself. Take out all the slides, pour a few drops of dishwashing liquid soap into each valve (one at a time). Get it all the way through, like you would when using oil. Use warm water and rinse out all the soap. Let it dry. This is very tedious, but has worked for me the couple times I've done it. 3) Like someone else said, use a thinner valve oil to semi-rinse out the gumminess. This has also worked well for me. Keep the lead pipe clean!
Q: Okay, I got this lawnmower its a craftsman with a briggss and stratton engine, and I use this mower to cut grass in the summer. My question is, I have to get this mower serviced like every 2 weeks. See, the problem is always the valves comes out of adjustment. It only has 2 valves, and a long time ago, I broke one of the studs for the valves. And some guy put another valve on it. Ever since then it hasnt ran good. Iv'e took it many times to get it worked on, and it will run great for about 2 weeks. Then the valves go out it's very hard for it to turn over, and it wont run. Whats the deal here? I hear that you should only have to adjust your valves once a year. What could be wrong?
i can explain it a bit more personally just email me if you want me to i will be happy to help with this sort of problem!
Q: Hi....my boyfriend is currently waiting to have heart valve replacement surgery and im a little worried about the whole thing...he doesnt like talking about it but if someone knows the answer to my questions I'd be so greatful!!First of all a little detail....he is 19, as far as i know he was born with this problem with his valve but it has got worse over time. he was also born with a hole in his heart but had an operation as a baby to fix this. he gets short of breath and often has pains in his chest. he says hes going to have a pigs heart valve to replace his, by open heart surgery (in a few months time). my main worry is whether the operations are always successful? and will this condition/operation affect his life expectancy??please if there are any experts in the field help put my mind to rest....!thanksshelly x
Open heart surgery is always a risk, as is any major surgery. The main risks are from infection and blood clots. The risks taper off very quickly within a few days after the surgery. Heart valve replacements are a common operation, with a high success rate. Life expectancy is generally better with a valve replacement; but not all valve problems reduce life expectancy to begin with. Sometimes the trade-offs are more of an issue with quality of life, with higher quality achieved with a functioning heart valve, so some people may be taking a medical risk to obtain higher quality of life. No one can tell you for certain what the outcome of this operation will be. The odds are very high that everything will go perfectly and he will fell better than ever before. There is a very small chance that he will end up worse To put the risks in perspective, a person i know had minor surgery to her knee - a simple 1 hour operation done at an outpatient clinic. Ten days later, a clot broke loose and she died in her sleep. I have had the same operation twice and didn't even miss more than a few hours of work. Another person i know had severe heart problems and docs said it was terminal, but an operation could prolong his life maybe 5-7 years. He had the operation and its now been almost 20 years and his cardiologist says his heart is healthy and there's no reason why he might not live another 20 years or more.
Q: what is the average cost to replace a valve core on a car? also can any car shop do it or do i have to go to a conrads etc.
You can do it yourself very cheaply. All you need to do is go to Walmart or a Auto parts store and get four valve cores and a valve core remover, then go to a gas station the has a air compressor. Remove the valve cores and put the new ones in, you don't have to let all the air out Just put the new valve core in and air the tire back up. I would check the old valve cores before I changed them or have them changed by mixing water and soap together and put in on the top of the valve core, if it bubbles then you need to replace them, if it doesn't bubble someone is just try to scam you.
Q: I have a 2000 jeep grand cherokee v8 4.7L it has a stuck valve making knocking noises my question is can i still drive it !? or is too dangerous
its only really dangerous to the engine , but possibly you if it quits at a dangerous location this sounds more like something else than a ''stuck'' valve . and personally i would not trust it until you take a further look into the engine and remove a valve cover to see what is causing the problem .

Q: I have a 96 Toyota Camry. I am putting about 4 qts. of oil in it a month. Other than this issue and some other minor things this car is in great shape. It doesn't appear to be smoking from the tailpipe and I never find any puddles of oil under the car after it has been sitting in one place for a while. What can be wrong with my car causing it to eat this much oil. Every now and then I smell a little burning oil but it is not coming from the exhaust. I'm thinking a valve job. Engine has 250,000 miles on it and it runs great other than the oil thing. I drive it 116 miles a day back and forth to work. Any suggestions??? Help!!!
The devil is indoors the extra advantageous factors. Is the motorized automobile indoors making use of variety the area you should look into. what variety homeowners. Any maintenance records. Is the unique distributors instruction manual secure. i'm going to have a Toyota mechanic placed it on a advance and look into under heavily. There are rubber boots that carry particular lubricants mandatory to the drivetrain that have a bent to crack and leak with age. Has the Air Cond plumbing been switched out to settle for the nice and comfortable variety refridegerant. Do the belts and hoses look right maintained? My advice is to bypass forward and stumble on extra present day variety with fewer miles. Older autos, even Toyotas with that many miles that have not been right maintained can develop right into a funds pit and pass away you stranded. making an investment extra funds now can advise saving multiple funds and subject indoors the destiny.
Q: Hi,I have a 2002 Honda Accord with 115k miles which recently gave a ECL. The Honda dealer identified this a P1457 and says that the EVAP bypass solenoid valve needs to be replaced1) is this referring to this valve?
If they are saying your ECM needs to be replaced, they're probably pulling your leg. What do they mean a 50/50 chance it needs to be replaced? That's a load of BS. Either it needs to be replaced or it doesn't. Very easy to tell. Simply put the key in your ignition and turn to the ON position (do NOT start the car yet). This should flash the lights on your dash. This would include the oil light indicator, check engine light, etc.. they should come on, then go off after you start the vehicle. If these lights flash, then go off after starting your vehicle, your ECM is fine. Also if the ECM is reporting a check engine light, chances are it's working properly. There is a VERY VERY slim chance it is reporting the wrong code, in which case the ECM could very well be bad, but this is very unlikely. If the solenoid is replaced and the issue persists, it is probably another problem that has triggered the P1457 code. They would need to check the train of what could be communicating with the solenoid in case another component has failed. Unfortunately I'm not sure about the other part of your question but just wanted to give you a heads up about the ECM.
Q: i have a nos tank that my grandfather gave me and i was wondering if i could get a scuba valve and put it on there so i can fill my paintball tank up with the air so i dont have to go buy a scuba tank
srry but if u do that it works very poorly so i would buy that scuba tank
Q: I wanted to clean my 2005 accord ex 2.4 idle valve. I'm not sure where it's at any pictures or websites ? And will cleaning it make any difference
Probably won't help. Idle Air Control valves are blamed probably ten times as often as they are at fault in Honda engines. It is mounted on the side of the throttle body and has a connector with wires instead of hoses. You don't mention why you are interested in the IAC valve, but if it is because of idle hunting (revving between about 500 rpm and 1500 rpm smoothly and rhythmically), a bubble in the coolant is by far the most common cause. If the coolant is changed and not bled the normal idle speed can't get hot coolant to the Fast Idle Thermo valve (FITV) so it figures the engine is cold and the valve opens to raise the idle. That raises the coolant to the FITV, which then decides the engine is warm so the valve closes, dropping the idle speed, over and over. Burping the coolant, by opening the bleed nipple on top of one of the radiator hose housings at the engine half a turn until a steady stream of coolant comes out, should stop that. Do it with the engine cold.
