Product Description:

pipeline ball valve-reduced bore High-performance

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.
(
)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
(
)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.
(
)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.

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.
(
)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.

()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.
(
)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:removeing the driver side valve cover?
valves don't knock and you can't get to them through the inlet manifold if it's the lifter you may be able to get it by taking the valve cover off but even then you sometimes can't and have to remove the camshaft
Q:how man cups does the miteral valve have.....?
Mitral valve has two cusps. It is located between the left atrium and the left ventricle , oxygenated blood comes from the lungs by pulmonary veins and drains into the left atrium then the left atrium pumps this oxygenated blood through the mitral valve into the left ventricle. After that the left ventricle contracts pumping the blood through the aortic valve to the aorta..
Q:Closed valve on a Rainbird sprinkler system?
they dont really stick from the winter. i would say if the valve has a problem the diaphram needs replacing on the inside of it. ( all you have to do is find the same kind of valve and take the old parts out of the valve and replace them, the top, and the solenoid with the new valve's parts. they can be anywhere in your yard. ive even found the valve boxes buried under bushes. some installers don't put them in boxes, they just bury the valves. if you know where any of the green boxes are open the lids and see what's inside. sometimes more than one valve will be in a box. turn the solenoid on the valve. ( this will be the peice that the wire are connected to on the valve. dont turn the solenoid too much or it will come out. just a 1/4 to 1/2 a turn or so maybe a little more or less. and when you find the valve that turns on the zone 8 that is not working that is the valve for that section. you may even be able to hear the valve trying to come on when the timer shows it is running. if not, then check for power at the valve. if no power. there is a short, bad connection, or bad module in the timer. if power- replace just the solenoid first. if that doesnt work rebuild the valve. if you have no luck finding the box with zone 8 in it then try a few tips. get a screwdriver and poke around where some other valve boxes are. they may be close together. use a wire locator or hire a professional to locate the valve and show you how to repair it. to manually open and close the valve- open upthe solenoid like i said. or use the bleeder if the valve has one.
Q:valve cover gaskets choosing help?
For the inexperienced I would choose rubber it is harder to mess up by overtightening and if you clean the surface it will seal good
Q:Valve cover gasket leak?
You never mentiond what type of Valve Covers you Had ..Aluminum or Stamped steel.... I am supposing that you have a Chevy engine...Now the FIX......I get 10 points if I get it right,,,,, Providing you scraped and cleaned All surface area; here it is..... If it is a Stamped steel Valve cover then you have to Flatten with a Hammer the area where the bolt holes are on the Valve cover.. Now Go to an Auto Parts store or a Performance Parts warehouse and ask for an EXTRA THICK valve cover Gaskets ,Usually made by Fel-pro or Mr. Gasket...they are made out of cork or Rubber.. They even have a gasket that Sandwiches a Thin Sheet of metal between two Neoprene Gaskets ..I think it is made by The same companies...I prefer this....I use to Build Race Car Engines and operated a Auto Machine Shop... Good Luck and God Bless...
Q:Seafoam and the pcv valve?
The PCV valve scavenges OIL VAPORS from the crankcase tthe VALVE COVER. Remove it and you will FEEL the vacuum when you put your thumb over it. It will POP the small pellet inside it. Foolow up with GUMOUT srpay and use BOTH to clean the THROTTLE BODY and the IDLE AIR CONTROL VALVE, the IAC is resonsible for mixing AIR with injecte4d fuel. A dirty IAC will RUIN mileage and clog up the converter. GOOD LUCK!!!

Q:1981 xs650 yamaha valves?
Remove both spark plugs. Remove all 4 valve inspection covers. Remove the Generator cover (L crankcase cover, round, 2 screws). It doesn't matter which side you start on. Turn the crankshaft in the direction the engine runs. Depending on which cylinder you're working on, watch that intake valve. When the rocker arm pushes it down, then comes back up, the piston is then moving up on the compression stroke. Continue turning until the piston is at top dead center. You can line up the T mark on the flywheel with the pointer, or look into the spark plug hole to see when the piston is at the top. Adjust the valve clearance for the intake exhaust valves on that cylinder. Repeat for the 2nd cylinder.
Q:My grandfather? Valve replacement??
I don't know much about it, but as far as I know, it's become a relatively routine procedure. Personally, the surgeon I'd want to do it on me is the guy who does 20 or more of them a week, instead of the guy who does two a month. The more frequently they do the procedure, the more adept they are at it, do you know what I'm saying? Good luck! I'm sure your grandfather'll do fine!
