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:when riding my motorcycle valves start knocking i took to a mechanic and they did not resolve problem. i have baby ed my motorcycle. dint know what to do at this point and time.
- Make, model, year? Knocking from the valve train? If it is knocking or ticking from the valves, your valves are out of adjustment. You need to remove the inspection caps over the valve adjusters. Most valves will have one of three types; 1. Hydrolic. 2. Bolt adjustable. 3. Shim. Take a valve lash reading to see if they are off. Ticking can also be caused by a lack of oil to the head. Make sure your engine oil level is where it is supposed to be.
- Q:In my condo, I have what appears to be a water relief valve of some sort right after my water inlet pipe. It's after the water cutoff valve. It's not the water heater relief valve. It has a leak, not bad, just a drip right now. It looks like a half baseball sticking out of the main inlet pipe with a bolt in the center of it. I've tried to tighten it but that makes the leak worse. First, what is this. Second, Is there an obvious fix to this. Third, if I have to get it replaced, what model/manufacturer can I get so that this doesn't happen for a long while. My plumbing is short of fifteen years old.
- It sounds like a pressure reducing valve. As you tighten that bolt it increases the pressure and made it leak more.It's probably not any good. I think if you go to a home center you'll find one . probably a Watts brand. They seem to be more prolific. Not hard to change.
- Q:I have a 1994 Toyota 4x4 pickup with the 4 cylinder motor. How do I check to see if the pvc valve works?
- Check on the top of the valve cover...it's usually connected to the air intake or air manifold.
- Q:If I flush the toilet the drama begins. While the toilet is flushing, if I lift the lift of the lid of the tank cover NOT THE SEAT, water shoots up straight in the air from the top/cap of the fill valve. This is a picture of a toilet fill valve.

- 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?
- Darn William B is a small engine tech today..He is usually a building maintence foreman..but I have seen him be alot of things depending on the question..when You broke the first valve and it was replaced, the valve seat itself was damaged from the first broken valve..simply inserting another valve will work for awhile, but now that the valve seat has been damaged..(which does not necessarily mean it will be visible to the eye) the new valves are going up and down and improperly seating...Most shops do not own valve seat grinders now days, and alot of them don't even do it..they simply tell you that you need a new mower..or throw a part in to make it temporarily work long enough to get the money and run..I am 54 and years ago I took a small engine repair course which we were taught to grind the valve seats when there was valve damage..they dont hardly do this now days..they make a tool for it that fits on a drill..all the way to high tech ones that have guages and meters and wont allow you to overgrind them..they need miched out..I am a 37 year experienced painter but I have done other things in my life..Small engines were a small part of them..
- Q:I have a suzuki bandit 1200 (2001) and I think it needs a valve adjustment. The engine is tapping at idle and while riding but I cant stop riding long enough to get it fixed. All the shops I checked with are booked for a week. Will I make the engine worst by riding it like this?
- Drop off the tapping bandit at the shop. The adjustment will be made and presto back in business. Dont't be silly look around for an independent garage owner that will do it for $50 instead of the $200 the dealer will charge. What do you mean---can't stop riding long enough. Blow the tapping in to a big thump and you might end up hospitalized---cause it broke.
- Q:where is the oil pressure relief valve at in a 2003 ford focus
- its in oil pump some engines have a oil filter relief valve in behind the oil filter that can cause this problem but not certain if your engine does but worth a check
- Q:My car (RWD) has vacuum leak and has the code PO171/PO174. I find some engine oil at the bolt well of the valve cover on the bank 2 side. Can the vacuum leak come from the valve cover? What is the main function of the valve cover? Thanks.
- First of all no. And. Second of all, to cover the valves. Little oil tubes come up to the rockers and lubricate them and the rods, springs, valve guides, top of valves. If you did not have covers than oil will spray all over engine compartment.
- Q:I have a 1997 ford aerostar and my mechanic just called me and said that the pop off valve needs to be replaced, but it is attached to the line so the hole line has to be replaced to. I want to try to find the pop off valve to see if I can get it b/c he can't find the replacement part, what I need to know is what it looks like. or where it is on an aerostar, because I have 5 more sitting in the driveway and I can look for it.
- Well, for AC, you can have the old school R12, that looks like a tire valve. New school is high and low side R134. These 134 ports are usually located on the fitting that is crimped to the hose. A new hose would be the only option. If you have the old R12 style, they sell an adapter for $5 that will convert it to a 134 high side.
- Q:primary function of a valve position?
- Are you asking about a valve positioner? If so, then a positioner is a device that measures the amount a valve is open or closed and then adjusts the motive force to be sure the valve is in the position the controller calls for. These are typically use in cases of very high differential pressure or where the valve actuator may be under sized or marginal.
