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: what is the difference between mitral valve prolapes and mitral regurgitation?
- Mitral valve prolapse refers to a condition in which the leaflets of the valve are large and floppy compared to the average. When the ventricle contracts, the valve closes and the flow causes a pop as the floppy leaflet fills with blood, much like the way the wind fills a sail. This extra pop can be heard with a stethoscope (like a click) but it can often be felt by the person affected which makes them more aware of their heartbeat than the rest of us. Mitral Valve regurgitation is a condition in which the mitral valve leaks after it is closed leading to a loss of efficiency of blood pumping and a drop in blood pressure. It is often a small leak and is of little consequence and is often associated with mitral valve prolapse. This leak can sometimes be heard with a stethoscope as a murmur under the left arm. The combination of both situations is known as Barlow's click-murmur syndrome. Old Doc
- Q: Im living in an a house previously own but abandonded , and im trying to get water, the thing is the pipe where the shut off valve is is dettached , and i dont know where to reattach it nor do i see the missing pipes to reassemble what does the main shut off valve attach to in my house?
- the water line is probably a copper 2 line coming into the house...where it meets the water meter and on the other side of the meter is a shut off valve then it goes into the house. perhaps the water is shut off at the street
- Q: I have a 97 Neon. The Canister Purge Valve circuit gives a code 31 stating that it has a problem. I've replaced the valve, which didn't make the code go away. I removed the battery for a few hours, and the code went away. I drove for about 2 weeks and the code came back on. If it's not the valve, where do I look next?
- Could you describe this canister purge valve? Not sure what you are talking about here. Is it part of the emissions, part of the radiator, or what. I am just guessing it's part of the emissions. In which case, I need to know if it has a smog pump. Could be the pump, could be a clogged up cat, could be a bad EGR valve. Need some more info to help beyond this point. Good luck.

- You have to remove VVA. Its a general tune-up #1cyl at TDC adjust: Intake valve: 1, 2, 4 Exhaust valve: 1, 3, 5 Injectors: 6, 3, 5 #6cyl at TDC adjust: Intake valve: 6, 3, 5 Exhaust valve: 6, 2, 4 Injectors: 1, 2, 4 You gotta use a feeler gauge for the valves and a pin tool (looks like an alen wrench)...(I don't remember the specs, so you'll have to fine those yourself) For injectors your need a special tool (timing pin) to adjust the height (there is also a spec for that) You'll need a pin tool for the valves and injectors plus wrenches to tighten the nut after the adjustment. Valves: loosen up the nut, put the feeler gauge between the rocker arm and the valve, turn the alen wrench till the rocker arm reaches the feeler gauge...make sure the feeler gauge is kinda loose between them but tight...then tighten the nut (there is a torque spec) Injectors: loosen up the nut, set the timing pin on top of the injector, turn the ajustment screw w/ alen wrench till timing pin reaches a lil notch, then tighten the nut till it's tight (also need a torque spec) Afterwards you'll need to adjust VVA... I'm giving you somewhat of a general idea. If you are attempting to do this, you should get a manual.
- Q: I started out playing trombone in middle school, then switched to euphonium as my main instrument. (I still play trombone for marching and jazz band, but I'm a little better at euphonium.) That being said, should I get rotary valve trombone or the one with axial flow? I only have a student trombone right now... And I have a professional Besson euphonium.
- First, you should know that a valve trombone is different from what you're talking about. Valve trombones have three or four valves, much like a baritone or euphonium. What you're thinking of is called a symphonic tenor trombone, tenor-bass trombone (less common), or a tenor trombone with an f-attachment. The difference between the axial flow and traditional rotary valve on the trombone is one of feel. The axial valve is designed to provide less of a change in resistance between playing the horn with and and without the valve pressed down. Some people prefer that resistance. Either way, the quality of the entire horn is going to be a better indicator than the valve section by itself. Your best bet is to go to a local music store and ask to try out all the professional models - pick which one feels and sounds the best to your style of playing.
- Q: Does anyone know where i can get a chromed valve cover for a 99 eclipse or is there a way that i can do it myself? id like to get one that has the etched 2.0 and DOHC words on it
- You can have it dipped in chrome and detailed for the lettering. It pricey but its the best way or you could try finding chrome spray paint that is good up to 500 degrees and do it yourself but it may not look as good.
- Q: the ac replacement valve seems to be leaking i was wondering what is the average cost of having it replaced..
- The ac replacement valve? Well, what you can do is to get the new ac to replace the old ac.
- Q: I just bought my first bike in 20 years, and as a result have had to pump up a bike tire for the first time in 20 years. I was dazzled to discover a type of tire valve that I'd never known about. The Presta.So of course, I need a pump with a special adapter, I didn't know to unscrew that nut at first so I accomplished a whole lot of nothing for awhile, and once I did open the nut, the pump kept slipping off the tire once I got anywhere near the tire' recomended PSI until I awkwardly held it in place while operating my pump with one hand, which of course meant less leverage and so while I got above the min recommended PSI, I couldn't get anywhere near the upper end of the spectrum. Why would anyone use these ridiculous contraptions? The fact that they are used means there must be some rationale. A brief internet search seems to find more forum posts with people saying the alternative (Schraeder) valves are more reliable and don't leak as much either.Educate me!

- Q: I am trying to bench bleed my master cylinder on a 94 altima...the directions state to attach the bleeding hoses to the outlet valves?? I haver four valves that merely state front or rear??
- The outlet valves are the bleeder valves behind the wheels the ones you open up when your bleeding the system.But to bleed the master cylinder mount it to the car and then fill master cylinder and then screw in the bleeder hoses at the locations where the metal lines hook up to the master cylinder and bend the hoses around back around to the top of the master cylinder so when your bleeding the master cylinder the brake fluid goes back into the top of it to get the air out of it.Then hook up your brake lines back to the master cylinder and bleed out the rest of the system to the wheels.Usually when doing this you start with the right rear bleeder behind that wheel but have someone there to pump on the pedal even when your bleeding the master cylinder first and then you do the rest of the system.On some cars bleeding the rest of the system starts with sometimes different wheels like the front and or the back.But on a usual bases you generally start with the right rear then the left rear and then the right front then the left front.But by bleeding the system check with a shop to find out what the bleeding steps are to bleeding the wheels outs at the valves each car is almost different to do.But the master cylinder is the easiest to start with when it comes to bleeding it but watch out when going to hook up the brake lines back to it because some brake lines are hard to hook up and what I mean by this the fiitting might get cross threaded when putting them
