Design Features of full welded forged steel ball valve
The body of ball valve is full welded,selects high quality forged material,and adopts the advanced forged forming technology to form two semi-spheres which are welded into a whole in the middle of the body.This welding technology differentiates the ball valve form others,and makes the valve more spherically,so the valve structure is more compacter,lighter and stronger.Besides,the middle direct welding realize highly accurate valve body manufacturing,makes fully and completely sealing between the seat and ball.The full welding instead of bolts completely avoids the outside leakage,so ball valve is the ideal product for under-ground,offshore working platform and under-sea equipments.
Adopting fixed plates or trunnion to support the ball
The top and bottom of the ball is supported by upper and lower fixed plates or stem and trunnion,and the ball is accurately placed in the center of the ball valve to achieve complete seals and precise movements.When plate adopted,the force exerted by the medium to the ball is distributed via the plate to the left and right bodies,so that the stem does not bear the blending moment from the medium,but only the torque from the ball rotation during the opening/closing of the valve.The low-friction PTFE Teflon composite bearings installed between the ball axis and fixed plate and between the stem and the trunnion can absorb ball moving action caused by the pressure of the medium.This structure brings stable actions and easy operations for the ball valves,and the required operation torque can be reduced,so smaller actuators can be used,and the cost is cut down.
ball valve seat is floating structure,means the seat can move along the medium direction,so that the seat can fit against the ball all the time.
（Ⅰ）Double piston effect structure seat of full welded forged steel ball valve
Seat design is special double pistons effect structure,it can ensure the seal wherever the medium flows into the ball valve.
（Ⅱ）Seat multistage seal strucute of full welded forged steel ball valve
As following graphic instruction,on seat bearing ring,set two soft sealing rings(A and B)and metal sealing spherical surface which can seal with the ball.Seat ring A is spring loaded,which seals the surface with the ball tightly to the surface to form an initial seat;When there is pressure generated from medium,the piston force is generated to make seal ring A elastically deformed and seal ring B fit the surface of the ball surface due to the piston effect caused by area difference,thus the second seal forms.When the medium pressure is rising.It will generate huge pressure to seal ring A and seal ring B,so the two seals have a greater elastic deformation,then metal seal ball surface compact with ball surface to form the third level of metal to metal seal.
（Ⅲ）Secondary seat seal device of full welded forged steel ball valve
As the above graphic instruction,the secondary seal device(seat grease injection valve)can be chosen according to the actual working condition,medium requirement,seal requirement,etc.Seat ring grease injection valve is a one-way valve,installed on the body,which can prevent the leakage and inject grease under the outside force.When secondary seal is required,there is a grease injecting channel and hole on the seat ring.The grease can form a seal between the seat and the ball,and then stop the leakage.

- Q:I am wondering if i can put a blow off Valve on my Crossfire and still get the same sound as if it had a turbo. the car is stock and i just got it so i do not know if it does have a turbo already. Can anyone help me with this.
- Doesn't have a turbo regardless of whether it's the 4 cylinder or v6 engine. EDIT: Blow off valves work by purging boost pressure (from the turbo) from the intake piping before the throttle body. Meaning, without a turbocharger there is no build up of pressure prior to the throttle and hence without a turbo a blow off valve is functionless (and it WILL NOT make a noise).
- Q:When I put my check valve on my air line the air doesn't come through the air stone but when I take off the check valve it works. Also I switched the sides of the check valve and it didn't work. Click the link this is the air pump.
- Or if you can, go to petsmart and get one there. Petco tends to sell sub-par items and livestock. If you have a tank that is bigger than your air pump was intended, then you will have problems. Say you bought a 10 gallon air pump for your 20 gallon tank. The strength of the pump is only able to push air down to counteract the average depth of a 10 gallon tank, against the pressure of only that much water. However if it were in a 20 gallon, it may not be able to counteract the water and the check valve (which shouldn't be causing much of a problem anyways). Make your line shorter and see if that helps. You don't need tons of extra airline tubing coiled around. Cut it down to the length you need, and try again. Remember, check valve should be OUTSIDE of the water, in the direction indicated on the valve (as to which side is in, which side is out), and it should be closer towards the pump itself. The check valve just prevents any water from dripping back into the pump.
- Q:Situation: The males in my family have mitral valve prolapse, while I do not.If anyone could answer some of the following questions, it would be amazing! Thank you so much!1. Is this an X or Y chromosome disease? (I thought since it was just guys, it'd b Y)2. If so (or not), is there any reason why I don't have it?Thanks again! (:
- Mitral Valve Prolapse Hereditary
- 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:I'm installing a shut off valve under my sink. can you tell me all the materials that i need to install it by myself because to hire some body else is very expensive where i live. i need to change the old ones because they are leaking very bad when i want to use the sink.thanks a lot
- its called 'an angle-stop' and if you have copper, its sweated on or compression fit. if its compression, get a crescent wrench and take it off at both pipes and take to store and replace same ones, but better quality. don't forget to shut off the water to the house outside! if its sweated on, you need to have someone that knows how to copper weld to do it for you. if its galvanized pipe, unscrew it like 1st and proceed with another like item or switch to copper with a dialectic fitting between both.
- Q:how much is a head and valves job for a 92 chevy silverado 1500, v8 5.0L, extended cab, 204,xxx miles
- Mileage? by potential of no longer working you mean a ineffective hollow (no longer Firing) good? {Low Compression?} 80% is Boarder Line working no longer, 60% is thoroughly ineffective. you need to have a Leak Down try carried out to be sure if the problem is Valves or rings; Valves (Rebuild Head(s) Valves), rings (complete Engine Rebuild), wintry climate; Will start up perhaps however the tension will Drain the Battery after some starts.
- Q:Sohc ZC (d15) honda I'm going to be painting my valve cover am I going to need new seals? What do I need to take it off and put it back on ? Please help I have the high temp sand paper all ready to go I just want to be ready
- Valve cover gasket. Make sure it comes with the spark plug tower seals or you need to buy them separately. It's best to bead blast the cover before painting it.
- Q:I am looking at buying a 2001 Pontiac Bonneville and the guy said the car's check engine light says it had a problem with the EGR valve and so he bipassed it somehow. He said a EGR valve isn't needed. Is this valve very important or needed? What does it do? Thanks
- Yes it's vital for the car to run right and for smog or emissions testing too. I'd highly wonder about that car bec what else did he by pass. If you've not read the ECM's codes how do you know the engine light isn't on due to EGR valve and other faults with car. Best of luck and I hope this helps
- Q:Hey quick Q, I heard somewhere that you could degrease the the reed valve? I love cleaning up my CR250 as much as I can. I just want to know if this is done, and if you could, tell me where I'm supposed to clean.Thanks.
- The flow of gasoline rushing past the reeds is enough to keep them clean. No degreasing is necessary. Are you sure you didn't hear de-carbonize the power valve? If so, remove the power valve and linkage from the cylinder. Remove hardened deposits with a wire wheel on a bench grinder. Clean the parts with parts cleaner.
- Q:Hey I'm high rite now and i have a checkup for mitro-valve prolapse tomrow, i was wondering if they will take my blood and see THC in me....
- Mitral valve prolapse exams look more anatomically than physiologically. Meaning, they will take a picture of your heart instead of looking at the chemicals in your blood. BUT a prolapse may mean that your blood does not have enough oxygen in it because your heart circulation is abnormal, they may take a blood sample to test the level of oxygenated blood relative to deoxygenated blood to check this.
