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.

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.
(Ⅰ)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
(Ⅱ)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.
(Ⅲ)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.
Multi-level structure of stem sealing
Figure6 shows the stem multi-level sealing by adopting"O"ring,flexible graphite and grease injection;"O"ring achieves the first level stem sealing;Replaceable flexible graphite realizes the second level sealing by the compression of packing sleeve and packing flange;And the third evel sealing is realized by installing assisted sealing injection valve to the packing box,and by designing with the injection groove and hole to connect with the stem injection valve,which can inject grease.
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.
(Ⅰ)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.
(Ⅱ)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.
(Ⅲ)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: Where are the valves. And how do I fix it? Will I have to buy anything? I have a 98 Honda fourtrax 300.
- ticking okorder /
- Q: I want to install a hks blow off valve on my car but is it true that i need a turbo installed first in my car or not.and are they legal in the state of californiapermitted,i want my car to make that air release sound when i shift gears,but it needs a turbo installed or can i still get what i want from a blow off valve without a turbo!!!!!
- teh valve is designed for use with a turbo to prevent over boost destroying things! hence we do need a turbo. vary rare to be worth fitting to a car eg installing a turbo. much better to exchange for a car with a turbo as standard ( also insurance etc is easier to sort) the gas pressure relief valve only sounds nice to boy racers. everybody else thinks it very geeky.
- Q: i just bought a junky trumpet, didnt come with a mouthpiece... how can i tell that the valves work? They press in and dont stick, but im not sure about their functioning. Also there are no caps on the valves, will this affect playing? lastly, it has a stuck tuning slide, how can i get this to work again?
- whilst i develop into in intense college, I performed on a 3C and had a particularly good sound. in my view, i could in no way visit a smaller, shallower mouthpiece to play intense. i could quite develop my chops and be waiting to do it on a deeper mouthpiece. In college, I switched to and nonetheless at present play a Monette B2, that's analogous length to a a million a million/4C, and characteristic an excellent sound, and might play a intense G (4 ledger lines above the staff) and up on it. i exploit it for any group I play in, marching, stay overall performance, musical theatre, etc... ultimately it boils all the way down to private preferrence. %. the mouthpiece that feels the terrific to you and nonetheless can provide a good sound. you do not pick it so great and deep that your variety and sound go through, and you do not pick is purely too small and shallow which you get too outstanding and tinny of a sound. wish this facilitates.
- Q: What exactly are valves and cylinders when talking about car engines? Say a car has 3 cylinders or 8 valves for example.
- There are intake valves and exhaust valves. On the intake side, the intake valve opens which lets the fuel/air mixture into the combusion chamber. At some point (measured in degrees of crank rotation) the intake valve closes, the air/fuel mixture is compressed and ignited by the spark plug. Then the spent mixture exits the cylinder when the exhaust valve opens. Valve configuration varies somewhat, but regardless of how many valves there are there will always be at least one intake and one exhaust valve. Some cylinder heads have 2 intake and 2 exhaust valves which is what is described as the 4-valve per cylinder setup. Regarding Car Cylinders, the answerer says Cylinders in a car engine are pretty much like rowers in a boat. But they are not. Rowers always row in synch with each other. Cylinders are made to be out-of-sync for smoother operation. The more cylinders you have, the smoother the engine runs. Compare a 1-cylinder minibike with a 4-cylinder motorcycle (both air-cooled), or a 4-cylinder to an eight... big difference in smoothness.
- Q: im 16 and im rly scared i have already been checked out by the hospital and they sed that i have a moderately leaky heart valve. They recommended me to see a childrens cardiologist since they dont specialize in children. i have to get another echo and some other tests done i think. im so nervous. whats going to happen to me??
- You'll probably have more tests done to see if you really have a leaky heart valve. It depends on which valve it is and what the cause is. The most common cause is to have a bicuspid aortic valve (two valve leaflets instead of 3). That can cause long term problems, so that is corrected by surgery to replace your aortic valve. Once that happens, you'll be fine. I'm not sure what you have, though, so there's no way to know for sure what your problem is. In general all leaky valves need to be replaced surgically if they're leaky enough b/c they eventually cause the heart to stop pumping well and lead to heart failure. The most common thing is what I mentioned, though. There's always a chance that your test was incorrect. Good luck to you.
- Q: What is a valve adjustment? I wanted to do one on my 1994 Honda civic ex cuz my friends told me I should do one but I wanted to know howmuch will it cost? And what will it do to my car in performance and gas consumption? My car right now has 155k miles.
- Leave it alone. Besides at 155k a Civic is junk not worth spending money on.
- Q: Kenmore washer ,cold water trickles in, pressure from faucet OK. Must entire valve be replaced?
- see if you can find a manuel on it also try tracing the wires that go to the valve and back track from there. there is also water level switches and tempture switches that might be messed up
- Q: I have a 97 ranger 4.0L that takes 10w-30 and I'm going to be changing the oil soon. It has some valve clatter I'm just wondering if I can use a thicker oil such as 15w-30 or maybe a 10w40?
- Valves don't clatter. Sticking or collapsed hydraulic valve lifter do. The use of the normal viscosity 5W-30 full synthetic oil contains a heavy dose of detergents. If gum, varnish or sludge is an issue, repeated use it may quiet things down. This is the least expensive thing to try first. If that doesn't do the trick it's time to (easily) replace the sticking hydraulic valve lifters. Thicker molasses oil may insulate noise while it's cold and heavy but it will never fix the issue.
- Q: i have a 1991 rm125 and i want to open the power valves myself can anyone tell me how to do thisTHANKS!
- Power valves are not in the intake area, but are in the exhaust side of the cylinder. Power valves open the exhaust port at high rpm and reduce the port size and usually lower the top of the port at low rpms. The Suzuki power valves are somewhat complicated so I would recommend a factory manual and a good parts break down before attempting to disassemble or service. Also a RM125 will run very poorly if the power valves are not functioning as designed.
