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.
(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: i would like to hear from anyone who has actually had the work done. i also would like to know if the valve worked.
- I suggest putting this question anywhere but in cars and transportation.
- 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?
- P1457 Honda Accord 2002
- Q: Ok I recently changed my pcv valve and today when I was checking my spark plugs I noticed and valve that looked exactly like a pcv valve on the passenger side valve cover iam not sure exactly what this valve is ?? I should note that I changed the pcv valve on the driver side because I noticed that it was just a hose coming out of a rubber grommet and into the back of the carb was that just a breather hose ? Thanks in advance for any info
- That other one is the crankcase breather, it goes to the air cleaner with a small clear plastic filter by the main air filter. It's not a valve so changing the breather filter is all that need be done with it.
- Q: I have a '98 Dodge Caravan 3.0 and the valve cover gasket is bad. How do I replace it?
- you are going to not like this first drain coolant 2 remove the throttle body linkage remove the pipe going to the egr to exhaust manifold [helps to use penatrating oil] remove assorted hoses to get to removing the upper intake plendeum {not the lower intake] [you need to put a shop towel over the open intake ports at the engine to keep any and all debries out of the intake ports to the engine] you should be able to see the valve covers by now remove the valve covers bolts remove the valve cover clean the gasket surfaces on the cylinder head [don,t leave ant debries in this area or in the valve cover [cleanlyness is a really good thing at this point in the build keep the crud out] there are some half moon seals that need to be replaced at this time located on the ends of each cylinderhead put a light bead of RTV high heat silicone on the rounded side of the seals and install the seals in thier half moon bores the RTV high heat silicone will kinda squish out of the seal don,t let the beead get carried away wipe of the sealent with a clean towel [shopcloth] not paper towels put a little RTV high heat silicone across the seal s flat side wipe flat with your finger install the valve cover gaskets on the valvecover [a little automotive contact cement for weaterstripping helps hold the gaskets reinstall everything fill coolant system change the oil and filter look for leaks a book or parts guy should be able to help find the right touque to tighten the bolts remember cleanlyness works here good luck should take about 8 to 10 hours note do not reuse any gaskets any where new hoses would not be a bad idea along with a thermostat ihawk3
- Q: the air valve, how does it propel a paintball in a blowback operated paintball gun how does the size/shape/?? of the valve impact how fast the paintball shoots?
- The majority of blowback paintball guns use a pin valve, which is opened when struck by the hammer. The hammer is held in the back position, with the spring compressed, by a sear. When the trigger is pulled, the hammer is propelled forward by the spring, into the valve. These sorts of markers generally use a “stacked tube” design, in which the valve and hammer is contained in the lower tube, while the bolt, which is connected to the hammer, is in the upper tube. The gas released by the valve is then simultaneously channeled up to the bolt to fire the paintball, and back to push the hammer back into the ****** position (hence the name “blowback”). Poppet valves are usually easy to replace and require little, if any, maintenance. The downside to this design, however, is its high operating pressure, which leads to a larger recoil and arguably less accuracy. The valve is usually designed to accommodate a specific operating pressure. Low pressure valves provide quieter operation and increased gas efficiency when tuned properly. However, excessively low pressure can decrease gas efficiency as dramatically as excessively high pressure. The volume of gas released by the valve directly affects the paintball's velocity. The velocity adjuster alters the pretension on the hammer spring which controls how long the pin valve is held open for, or more correctly how much gas must be released to push it back into the ****** position. EDIT - Sorry but wouldn't even know where to start on designing a valve.
- Q: For those of you that have had a heart valve replaced, why did your heart valve go bad?
- A good friend of mine ignored his bad cold symptoms and was diagnosed with pneumonia when it already affected his heart valves.
- Q: If this prolapse considered heart disease. I was diagnosed years ago with it . My doctor at the time told me this is not heart disease and now I googled it and it said this is heart disease. Another person said this is valve disease ? I never asked my current doctor if it was or not. She checks me every 3 months because I have a heart murmur that you can have with this prolapse. whenever I have filled out questionaires about health history when they ask me if I have heart disease I always check no. If this considered heart disease or valve disease. I've never been to a cardiologist for it. Should a person have at least one evaluation from a cardiologist for this ?
- Its a valve disease. It is a valve between the right atria and right ventricle within the heart muscle. Mitral valve prolapse simply is the fact that the valve does not completly close once the blood is pushed down from the atria where the deoxygenated blood is where the new oxygenated blood will be after it goes through the pulminart artery to collect oxygen from the lungs, then comes back to the ventricle. What then happens because of the prolapse is it has a little regurgitation, or spitting back up some fresh oxygenated blood back to the atria, and then continues to the left atria through the corniary vein. Hope that explains why its more of a valve disease than the heart disease. Heart disease has to deal with the heart muscle. And its chambers. Then you have corniary artery disease which focuses on the arteries and veins of the heart and of course the valves which includes your aorta, bicuspid (mitral valve), and your tricuspid.
- Q: Hi guys, my parents had me install a new faucet in their kitchen sink. It works great and everything, but after the install the hot water pressure basically decreased greatly. The cold water pressure is fine, but I believe after I had turned off the hot water at the shutoff valve, something in the valve got messed up and is blocking the water supply.
- Copper pipes are usually soldered. You might want to call a plumber for this.
- Q: like they say on 4 strokes you gotta go get valve jobs, and they cost bout 300 they say? well what does the mechanic do? can it be done at home and your just adjusting them?
- Take the head to a machine shop you have to grind the valves or replace then,Same with the seats Then replace the guides and adjust the valves Not a driveway Job
- 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.
