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.

Q3:How can I place an order?
The only one thing you should do is to tell us the sepecification about type 、quantity and mode of transportation, then we will send you quotation within 24 hours.
- Q: What would this envole, can i size up/down the port on the existing valve with just changing the mechanical componts.
- On okorder /
- Q: What are the types of control valves used in the oil industry and how are they applied.
- There are other manual control valves and on/off automatic valves that are used a various places for remote or emergency control. These can be globe, gate, ball, plug or butterfly valves. They can be actuated by pneumatics, hydraulics or electric power.
- Q: How do you ajust valves on a 1955 chevy 265 cu, in engine. I Believe they are hydralic valves.
- my first engine in my 57 chevy sure miss that old thing still kicking myslf in the butt for letting it go. there are two adjustments hot and cold, is the engine running,if so just pull the valve cover off and with the engine running just adj the 5/8 bolt on the rocker to take the tapping out at the same time listen to the sound of the engine for over adjustment
- Q: Hello,I've not found a perfect fit using a solenoid valve for gravity fed irrigation system. Primarily because it requires a constant drain on the battery while the valve is open. Is there a motorized valve to fit the bill? One that momentarily requires electricity to open and close the valve at 12v DC or less to work in gravity fed system?
- I don't know how it specifically wires. There are two strategies for latching devices. One is a solenoid with two coils. Pulse one to open, pulse the other to close. The other strategy is to have one coil. Apply polarity in one direction to open, in the other to close. I suggest googling for latching solenoid valve, and/or checking out the major irrigation (or sprinkler) manufacturers for their offerings.
- Q: its rated 120 VAC/26VA (3 prongs, one for ground) . I also have a horizontal level switch for liquid with rating 120 VAC/0.28 A (the switch will connect when the water level reach the target) normally open.How can I wire them so that when the level reached the valve will close and water will not flow into the tank? The switch is inside the tank and the valve connecting the pipe for feed water. Thanks
- I okorder / and if they dont have the answer for you, then go to the parts page and buy the book. - its cheap
- Q: I recently adjusted the valves and put new valve covers on my bug and now I have a leak around the fron corner of one of my valve covers. What happened? What can I do?
- new seals + get rid of the cheapo chrome repros and put OEM covers back on.
- Q: My car had white smoke coming out from the exhaust.After talking to my mechanic, he said that the valve seat is faulty in which i suspected earlier. He also told that my car need to be overhauled. What would a faulty valve seat cause my engine?
- It's the doctrine of alternative and end result. You made unhealthy offerings and are actually paying the penalties. If you had constant the EGR valve proper whilst the investigate engine gentle got here on, you do not need had the tickets. Cost of an EGR valve is beautiful small. But you selected now not to try this. When the plate ran out, you knew it was once out, and made the alternative to hold riding. When you obtained the primary price ticket you might have stopped then, and constant the vehicle and obtained present so there could be no MORE tickets. Again you made a alternative now not to try this, and hold riding, and get extra tickets. How lengthy could it have taken for you, or your husband, to make a sensible mobilephone name to the courts and give an explanation for your clinical situation? The courts could have gladly given you an extension to your look. But once more you made a alternative to disregard it till there was once a warrant on your arrest. Even now you've gotten made a alternative to invite a number of strangers at the Internet as an alternative than name the courtroom approach or authorized help to discover your choices. So, welcome to the exclusive global of penalties. Good Luck.
- Q: the air valve, how does it propel a paintball in a blowback operated paintball gun how does the size/shape/?? of the valve impact how fast the paintball shoots?
- The majority of blowback paintball guns use a pin valve, which is opened when struck by the hammer. The hammer is held in the back position, with the spring compressed, by a sear. When the trigger is pulled, the hammer is propelled forward by the spring, into the valve. These sorts of markers generally use a “stacked tube” design, in which the valve and hammer is contained in the lower tube, while the bolt, which is connected to the hammer, is in the upper tube. The gas released by the valve is then simultaneously channeled up to the bolt to fire the paintball, and back to push the hammer back into the ****** position (hence the name “blowback”). Poppet valves are usually easy to replace and require little, if any, maintenance. The downside to this design, however, is its high operating pressure, which leads to a larger recoil and arguably less accuracy. The valve is usually designed to accommodate a specific operating pressure. Low pressure valves provide quieter operation and increased gas efficiency when tuned properly. However, excessively low pressure can decrease gas efficiency as dramatically as excessively high pressure. The volume of gas released by the valve directly affects the paintball's velocity. The velocity adjuster alters the pretension on the hammer spring which controls how long the pin valve is held open for, or more correctly how much gas must be released to push it back into the ****** position. EDIT - Sorry but wouldn't even know where to start on designing a valve.
- Q: When looking at the head on my chevy 350 how do I determine which is the intake valve and which is the exhaust valve?
- Intake valve will line up with the intake port from the intake manifold and the exhaust valve will line up with the exhaust port going to the exhaust manifold or header....intake is usually larger of the two.
- Q: Hi, in the heart, blood flows through the AV valves and enters the ventricles once the atria have filled up with blood. What opens the AV valves? Fluid pressure from the blood or the SA node pulses?
- The opening and closing of the atrioventricular valves is controlled by the differences in pressure across them: When blood passes from an atrium to a ventricle, the atrioventricular valve is pushed open (and the papillary muscles relax and the chordae tendineae lose their tension, becoming slack). At the next stage in the sequence the ventricle contracts. This forces blood out from the ventricle into the artery via which it leaves the heart. This contraction of the ventricle and the corresponding increase in blood pressure within that ventricle also presses the cusps of the atrioventricular valve together until their edges meet, closing the valve. At the same time, the papillary muscles contract and the chordae tendineae tighten - both of which also help to prevent the cusps from enabling the atrioventricular valves to open. When in the next stage of the sequence the ventricle relaxes and the atrium contracts, the blood pressure situation is reversed, the relaxation/tension of the papillary muscles and the chordae tendineae also reverses, and the atrioventricular valve allows blood to pass from the atrium to the ventricle again.
