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 have a 87 cbr600, consumes oil at a considerable rate. Took the engine out of the frame and disassembled cylinder head, block and pistons and found there is a thick layer of cooked-on oil over all sixteen valves. I figured the oil consumption was due to bad rings, but could it have been the valves?
- Valve guides and seals will, but not the valves. Bad valves will lower compression on the engine and reduce performance but won't burn oil. The deposits on the valves are most likely from oil burning, getting to the heads past the piston rings. The rings aren't hard to change if you already have the head off... pull the cylinder block off and the pistons will be accessible. Getting the block back on can be tricky as you have to get the rings compressed. Might take two or three people. Good luck. Reassembly is harder than disassembly, but you probably already know that. Make sure you get the cam marks exactly right!
- Q: large veins contain one way valves, which keep the blood flowing in one direction. why dont large arteries need similar valves?
- The aorta and the pulmonary artery both start at valves from the heart, but I don't know if you could say they have valves. A lot of arterial flow is regulated by smooth muscles which constrict to direct flow to other areas. These are a kind of valve too.
- Q: I wanna do it myself My dad knows how But i must buy the parts I have a rmz250 and i was wondering if u can jus buy valves and seals and jus put them in without grinding since the seals are new i heard u must gring the seals to get the valves to sit flush againt the metal serface but cant u jus buy new seals and retainers and put that in plus the valves and ur done?
- It all depends upon the wear in the cylinders of the engine. Usually they are honed and made smooth again prior to installing the new rings, seals, etc.
- Q: 1990 Pontiac Sunbird 2.0L Fuel Injected has EGR Valve, I can suck and blow through the hose connected to it, an I supposed to be able to do this, or not...? It looks old, like it's been on the car forever...
- You can do a simple test of the valve - take a clean hose into the input - suck on it and place your tongue against the hose - it should hold vacuum and your tongue for about a minute. If it doesn't, replace the valve. They can also get clogged with deposits that can cause problems. For one that old, you may do well to just replace it.
- Q: I have mitral valve prolapse and I don't get why only some people get chest pains? and what causes people to get chest pains with M.V.P (mitral valve prolapse), like me. PLEASE HELP!!!!!!!
- With MVP, your mitral valve is smaller due to extra tissue. This makes it a little bit harder for blood pumping through the valve to get through, which can often times cause an aching pain. As far as I've seen, this is not life-threatening and the pain can be treated with over-the-counter painkillers. Imagine you kink your garden hose while it is running. The water can't get through the hose and the pressure builds up. When you unkink the hose, the water flows freely. Your mitral valve has a permanent partial kink or blockage. The blood behind that partial kink can get blocked up and cause pressure in your chest. Be sure to get regular check-ups with your doctor, just to be sure your MVP is stable. Your doctor will also be able to suggest some pain remedies.
- Q: do I need a new water heater or can this ne be fixed?
- It can be Fixed. Try as Follows 1) tighten it up 2) Put some Silicone around it 3) Buy a new one a replace it. Make sure that you cut the water OFF before you Change anything out. Pop Off Valves are Not Expensive and are Very Easy to Change out. You need a 10 or 12 inch Pipe Wrench and some Pipe Dope. That is all. You unscrew the old one, put Pipe Dope on the Threads of the New one, and Screw the new one in. Takes about Five Minutes and maybe $ 10.00.
- 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: How come my boiler supply valve isnt letting water into my boiler, i have a cold water supply hooked up to it with the valve on i have tested the copper pipe goin into it and water flows into it, but when It reaches the valve it stops. I understand that it my have a backflow preventer in it and I am wondering if that could be malfunctioning. The hole you see on the front is where my expansion tank screws in. Also where could I get a new Valve. Thanks.http://img149.imageshack.us/i/boilerfillvalve.jpg/
- I work on antique steam boilers and engines for a hobby and if your supply valve isn't letting feedwater into the boiler, I'm going to tell you right now that you potentially have a VERY dangerous situation on your hands. Until you get this issue resolved, I would recommend that you not steam this boiler up under any circumstances, unless you have a backup feedwater delivery system that is working correctly. Many people don't know this, but a low water condition in a boiler under steam is essentially a ticking time bomb and can result in a fatal explosion. As to what may be causing it, I would say it's possibly one of two things: 1.) The check valve has been installed backwards and the flow of water is basically pushing it shut. 2.) The check valve is installed correctly, but is frozen shut due to corrosion and scale. Either way, I would have a certified boiler inspector come out and take a look at it; he can probably tell you more than I can.
- Q: How hard and expensive is it to replace a pvc valve , hose, filter on 1991 Dodge Caravan 4 cylinder
- The Positive Crankcase Ventlition(PCV) does 2 things, 1.the valve prevents backfire pressure from entering the crankcase(oil pan area), the pressure could damage oil seals and gaskets causing oil leaks. 2. as the engine runs, as small bit of combustion gases slips past the piston rings and into the crankcase, if it does not have a way out it can damage the oil seals. these gases are sent back through the engine and out the exhaust. the hoses just directs the flow of the system. the filter keeps trash from getting into the crankcase. the flow of the system is as follows:filter-hose-valve cover-crankcase- hose- PCV valve-intake manifold-cylinders-exhaust. if oil is developing in the filter, there is a clog in the system somewhere or you have bad rings
