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 heard alot about blow off valves making your engine run rich, but I want to get a blow off valve or bypass valve when I get a wrx. (I know some people think they're gay) but i dont care how loud it is, just want that sound. so what's the difference? I've been looking at this one:
- A blow off valve releases the air into the atmosphere which gives you the noise their known for. A bypass valve releases the air back into the intake, like a stock BOV on most turbo cars including the WRX they are also known as recirculating BOV's, and do not produce the sound that a atmospheric BOV will make. A recirculating BOV will not cause you to run rich, and thats why a lot of people recommend them unless you are running a bigger turbo/ lots of boost. However they do not always make you run rich, and i would suggest that if you do get an BOV to just install it and not mess with it. If you mess around with the spring on them it can cause compressor surge which you do not want. However, I have used the hks ssqv with none of these problems.
- Q:I have a 2001 Chrysler 300 m. About a year ago it cut off on the interstate. The mechanic told me my timing belt broke and i had three burnt valves. The timing belt is already fixed, but I was wondering what parts were needed for the other. also what is the estimated price to fix this?
- Burnt valves or, far more likely, bent valves. Either way, you'll need to basically overhaul the top end - you'll need to replace the bad valves and the top end gasket set along with any machine work that may be necessary. Estimates will vary greatly from facility to facility and also from different areas. To get a valid estimate for your locality, you need to get local estimates.
- Q:is a 4 cylinder 16 valve.... 5 stars for the best answer....
- mazda dealer or find one in the junk yard.
- Q:Okay, so veins have valves to help counteract the pull of gravity. I'm wondering, do the veins in the head have this same adaptation, seeing as these veins are simply bringing blood down to the heart, and are not pulling against gravity.
- No. They wouldn't work... Valves only allow blood to flow one way. If the valve allowed flow out if the head then it would always be open (unless you went upside down), so they wouldn't be needed. If they stopped blood flowing out if the head...well...you'd have a big purple bloaty head.
- Q:hey...im kinda confusedis cochlear an artificial valve???and if not..what is an artificial valve??
- Hello, i found this information online, hope it will be helpfull... ?Artificial valves can be used to replace damaged valves in the body that are no longer functioning to keep blood flowing in one direction only. ?Most artificial valves have a fabric ring surrounding them, which allows a surgeon to sew the device into place during implantation. ?Where appropriate, artificial valves are constructed from collagen-rich materials, such as pericardial tissues which have been obtained from pigs or cows and treated (to denature any animal proteins), to minimise the risk of rejection by the human body. Other materials used are cobalt-chromium alloys, low-temperature carbon and titanium alloy with pyrolytic carbon discs or balls.
- Q:what is engine valve timining ?
- The valve's are in the head or head's and they need to be lined up with your crankshaft in order for the engine to be in time , if they was'nt in time with the crank they would hit at the wrong time and your engine would be junk.
- Q:I've found a little beemer that's only $800. I would like to have it as a 2nd car that I'll use in case something's wrong with my main car to loan maybe once or twice weekly to my neices (16 yr. old twins). The seller says it needs a valve job. My question is, will the valve job cost me more than the car?
- almost the work is alot cause you have to practicaly take the engine apart. and its a beemer. look to spend bout 700 on the job (gaskets, labor)
- Q:my valve cap is leaking slowing how do i fix it what part do i need
- The cap on the valve is just a dust cap designed to keep dirt out of the valve. To determine if the valve is leaking, move the car until the valve is at the bottom pointing up. Put a little water into the valve and watch for bubbles. Bubbles confirm the valve is leaking. You could try replacing the core with a little valve wrench (you will lose all the air in the process) or go to a service center and have them replace the valve. You cannot replace the valve yourself. If no bubbles, you have a leak in the tire or where the tire joins the wheel. Any tire service center can find and fix the leak.
- Q:The water won't drain around my outside shutoff valve. The faucet at the valve is not dripping any water. Could it be underground problem?
- Most homes have a main shutoff valve that goes from the street to the lowest part of the house. usually, they may also have another valve from lowest part of the house to the water fixtures. Ur main drain line is usually 4 feet or more away from the supply incoming line. Your home's outside shutoff valve is called a valve for the supply from your city water. It has nothing to do with your drain system. If you see water coming up from that outside shutoff valve, then a professional plumber needs to dig up the dirt around the valve and replace it. Usually there are no fixtures at this main shutoff valve, unless you are talking about an outside valve for a garden hose? So can u pls rephrase your question?
- Q:Hi. I looked at instructional videos for installing shutoff valves and instead of simply unscrewing old valve, the plumber simply cut the copper pipe. Is this necessary? Why can't I simply unscrew old shutoff valves from copper pipe?
- Most are soldered on and need to be cut off.
