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:How serious are multiple leaking heart valves?
Depends on how severe the leak is. If multiple valves have only trace leakage then no its not more worrisome then someone with Mild, moderate or severe leakage in one valve because trace leakage is a very small amount and almost everyone one has some. Now if someone had multiple valves that were moderate or severe yes that is more worrisome then some one with only 1 mild, moderate or severe valve leakage. If multiple valves have only mild leakage i think 1 valve with severe leakage is still more severe. I am NOT a doctor so this is just things that i am fairly sure about but not 100% sure of. Go to a cardiologist and ask him/her if you want a reliable accurate answer.
Q:EGR valve 2000 ford taurus ?
Just because you have an EGR fault, doesn't mean it needs an EGR valve. A qualified shop will be able to test an EGR valve sticking or stuck. If the valve is actuating normally then the passages connecting to the EGR could be blocked, in most cases removal of the intake plenum will be required to clean these passageways. Carbon gets built up and do not allow exhaust gases to flow and when there is a restriction you get a fault code that reads egr insufficient flow. Have a quality repair shop determine if the egr valve is actually to blame, most places like firestone and the like will sell no matter if it needs it or not. Good luck, if you have other questions, edit your question.
Q:EGR Valve question...?
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:Tricuspid Valve surgery?
Any type of valve surgery involves exposing the aorta of the heart, therefore it is a form of open heart surgery. Over time, this has become a relatively basic procedure for heart doctors and it has a success rate of almost 80-95%. There is a chance that you might need another surgery afterwards, but that only happens in about 5-10% of patients that get the surgery. The survival rate for this operation is very high and only 5-10% of patients experience any negative effects during the surgery. This includes infection, stroke, allergic reaction, or bleeding. I will keep you in my prayers Alex. Best of luck to you!
Q:How to remove sprinkler valve?
is it the valve your trying to remove, or the sprinkler head? if its the valve, there will be two pipes, one in and one out, just unwind the thread at end end of the valve, If its the sprinkler itself, then there should be a pipe under the sprinkler(swing joint) just grab the whole body and unscrew ( make sure you grab the whole sprinkler and not just the top, you may have to dig around it
Q:my valve cap is leaking slowing how do i fix it on my 95 jeep cherokee?
It might be just the core that is leaking but I would have a new stem put in to be on the safe side.
Q:Leak from Pressure release valve?
Michael is correct here. The TP valve is an integral part of the unit and should be replaced if leaking, not merely flipped open and closed a few times and then forgotten. Besides the folks that are telling you to flip the lever open and closed are forgetting about shutting down the water supply first. If you don't shut off the water before doing this you'll have a fair amount of hot water splashing out on the floor, and if it's overheated water it could very well scald parts of your body. It's extremely dangerous to take the advice of strangers, on a forum such as this, about something like this that can cause you much trouble and grief. If you are a handy person it's a fairly simple repair to replace one of these. Just turn off the water supply valve to the tank, if it's separate, if not then shut down the house supply. Many people say you need to drain water off the tank so as not to get any on the floor, and if that's a big concern, then it's not a bad idea. However, once the water is cooled, with the supply shut down there's no more pressure and the tank is similar to a straw full of water with your finger over the top. The water won't flow out easily without an air supply above it. So, if you have your pipe wrench ready and can take the old valve loose, have the new one taped with teflon tape on the threads and ready, when you unscrew the final threads of the old one, stick the new one right into the hole and thread it in. You won't lose enough water to be concerned about and you'll have a new pressure relief valve in place. Be sure to tighten it down good. Refill whatever water has left and check for leaks.
Q:will fuel system cleaner help with an egr valve?
No it will not help, in any case, it is cheap to replace.
Q:Spinal injury and leaky heart valves?
Maybe but usually MVP doesnt give people much problems and if it does usually sudden
