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:Do veins in the head and neck contain valves?
no they dont have valves
Q:Tire valve stuck on my bike?
What causes the valve stem to get like that. is from riding it with an almost flat tire with very little air in it. . Let the all the air out of the tube ,. pull and tug on the tire to rotate it on the rim until the valve stem is standing strait up again. Then refill with air. But often when you ride with low air, it ends up making a hole in the tube.
Q:Can water inlet valves for washers be repaired or rebuilt?
You probably can not find a rebuilt valve or get the parts to rebuild one. If needed, it will probably need to be completely replaced. There is a good chance you do not have a valve issue. Turn the water valve off and remove the cold water line at the back of the washer. Inside the hose or on the washer itself, there should be a metal screen in the line that somewhat filters the valve and protects it from getting clogged with sediment. Remove the screen and clean or replace it. If the screen wire is not at the washer end try the valve end of the cold water line. While your there you may want to clean the hot water side also. If you are unable to clean the screen, new ones are available for minimal money at hardware stores. Yes the screen wire is necessary, by removing the line additional sediment may very well go into the valve when you turn on the water and cause a valve problem if you don't have one now.
Q:Hot Water Heater Pressure Valve?
Tap that valve gently a couple of times with a hammer. Those valves are rarely used and sometimes stick. Remember, I said gently. If that doesn't make it close, replace the valve. Keeping the cold water shut off prevents the heater from filling. If there's enough pressure in there to keep allowing hot water out, it will eventually lower the water level in the tank and could damage the heater. Here's how to fix it. If it's a gas heater, turn the thermostat to pilot. Open the drain and lower the water level in the tank, or use this opportunity to drain it completely and flush the system. Remove the old TP (temp and pressure) valve and take it to the hardware store to use as an example for a new one. Replace the valve and hook up the drain. Close the drain valve near the bottom of the tank and open the cold water valve on the top. You can leave the TP open until water starts to come out of it, to allow you to burp the system. Now, turn the heater back on and set the temp to 120 degrees f. I'm a little concerned that the heater is not plumbed to drain into the house plumbing or at least to the outside where it won't cause any water damage. Good luck.
Q:Where can I buy a trigger valve?
Don't okorder.com/
Q:Clogged EGR regulator valve?
The thing you did not say was if you had any codes. If the valve was stuck and that would have to be in the open position you would have codes for the O2 and the EGR. And that includes the answer from Cleonitro. Your more likely to have dirty throttle body butter fly's and a dirty air by pass or MAF sensor which ever your vehicle has.
Q:What kind of valve packing material should I use for my shutoff valves?
Well if you talking about the water shutoff valves under sinks then you need to first shut off the water comming into the house at the main shutoff valve near the street , Or at a line comming into the house that connects up to the valve you are trying to fix or you may take a slight bath while trying to fix the valve that wont shutoff. Then Go to the shutoff valve you want to repair in that line where you shut the water off at and unsrew the handle at the base of the handle shaft using two wrenchs to hold both the nut on the shaft while using the other to hold the shutoff valve .this will prevent twisting the valve right off the connecting lines. Most of the time you will find it has a rubber gromet attached by a screw to the handle shaft.this is what you need to replace with a new rubber gromet which you can get in an assortment box at wal mart or homedepot or lowes for a low price. If you are using teflon thread or jointcompound you are repairing a Pipe joint leak where water is leaking externally of the pipe,not a shutoff valve leak .
Q:Cam carrier/ valve gaskets replacement?
valve cover shouldn't be that much of a problem as long as you have some basic tools and some mechanical ability. Take it that its a 4 cylinder car, the size of the motor is very helpful when looking for tips. Just don't over torque your bolts when replacing. 89 in lbs is about normal on gm's valve covers
Q:What are the advantages of having larger valves over two smaller ones?
Larger valves allow for more volume of fuel/air mixture to be introduced into the combustion chamber. They give an engine more horsepower but can compromise efficiency in the long run. I would rather have smaller intake valves and larger exhaust valves. The advantage to that is better flow of the exhaust. 40 percent of an engines total horsepower and torque comes from exhaust flow. If a person wants more fuel in the chamber all they have to do is change the camshaft to one that has a longer open duration. This will let the desired amount of fuel/air in where you need it.
Q:EGR Valve Circuit code P0403?
if your valve was carboned up then you Dp sensor is probably clogged as well and that would cause the light to come on and it would give that code. You can more than likely take it off and clean it really well with something like LPS or brake cleaner...carb cleaner would work also
