Products Description of Swing Check Valve

Check valves are used in pipes under pressures between PN1.6~16.0MPa(Class150~2500Lb), working temperatures-196~600, They are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power gene-ration to prevent the backward flux of the media.

The main structure features of Swing Check Valve:

1The products feature a reasonable structure, reliable seal, good performance and nice modeling.
2
Either soft or hard seal can be selected for the product upon different working conditions.The sealing face is built up with Co-based 
carbide alloy, leaving a better wearability, corrosion and scrap resistance and a longer duration.
3
Small opening pressure, the disc can be opened fully with a very small pressure differential.
4
Inside-set bolt-bearing structure reduces leakage and reliable use.
5
PN≥16.0Mpa (class1500), the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along 
with the pressure rise so as to ensure the sealing performance.
6
Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirements.

Q:What are the names of the main arteries and valves?????????REALLY NEED ANSWERS TODAY!!!!!!!!!!!
Main arteries: Aorta (oxygenated blood from heart to body), Pulmonary Artery (DEoxygenated blood from heart to lungs). Main Valves: Tricuspid valve (separated right atrium and ventricle to ensure correct flow of blood), Bicuspid Valve( separates left atrium and ventricle), Aortic Valve( ensures blood flow from left ventricle into aorta). hey sorry only saw ur question today:P hope it helps!
Q:I have a mountain bike that my brothers left me. the tire in the front is a normal s valve, the one in the back is a presta valve. now this was ok because it was fully pumped up, but then it popped on the road, so i got a new tire ad put it on and was all ready to pump it up but when i tried to pump it no air would go in. so i looked at it a while and i figured out the top unscrews, so i unscrewed it and put the pump back on and started pumping, but after a while i figured out that no air was going in the tire and now i'm very confused.
You have to re seat the pump nozzle and try again. Sometimes you have to push down on the valve to unseat the stem, it gets stuck fast and wont let air in.
Q:I heard alot about blow off valves making your engine run rich, but I want to get a blow off valve or bypass valve when I get a wrx. (I know some people think they're gay) but i dont care how loud it is, just want that sound. so what's the difference? I've been looking at this one:
Its a Cavalier guy, purely a complex new call with greater potential. Do because of fact the others say.. get a automobile with a constrained slip, something which could preserve fairly of torque, and save your self alot of headache (and it will nevertheless have some resale) interior the top... its no longer as great as they declare it to be... Chevys havent replaced lots over the years.. they have been acceptable with their slogan. Like a rock.. sink in basic terms as rapid.
Q:i have a puegeot 306 turbo diesel and apparently removing the EGR valve helps with engine noise and the smokeyness of the car. Is there any downside to removing it?
It will throw off the computer, and cause the check engine light to come on. Other than that, no.
Q:I been playing the trombone for 6 years, do you think i could learn to play the baritone easily,which baritone is easier,3 valve or 4 valve.
Some baritones have 3 valves, but the others have 4. The 3 valved ones are baritones and then the 4 valved ones are euphoniums.
Q:Is it supposed to go on or only in cases when the power goes out??? I bought this pump and the directions are horrible!!! There isn't room for both the air stone and the check valve!! How does this stupid thing work???
Check valve designated that it lets air go in one direction and stops water from going in reverse direction. For example if your airline gets disconnected from airpump by accident and drops on floor water won't gets syphoned out frmo tank to floor. You'd be surprised how much water can end up on floor in this scenario ;-) In order to install check valve you have to cut airline somewhat in halfs and put your checkvalve between pump and airstone. Arrow shows direction in which it passes air.
Q:Hi, I just got my 20 gallon freshwater aquarium yesterday and set it up today with the filter,water, pump,etc... I bought an AquaCulture 20-60 gallon double outlet air pump and didnt realize it had two valves. I only need to use one though ...what should I do??p.s. The bubbler thing that lets the bubbles out is a rectangle and its long but it isnt working in the middle of it...? would that be because of the double valve?p.p.s. the pump came with two check valves.Thanks, Sarah
If the pump doesn't come with any method to shut off one of the outlets, you can combine both outlets into one by using some tubing and a T-valve. You can also use an air valve and some tubing on the unneeded outlet to dead-end it, though that method may be a bit more stressful on the pump.
Q:This valve has flow indication embossed on their body.
the gate valve is a very important one in flow measurement and also used to help the measure of flow. for example if you know the pneumatic comparator operation, you can easily under stand the gate valve. the gate valve is mainly used for to adjust the float in the tube to zero position or the clearance value.
Q:i just replaced the head gaskets on my 1991 Acura Legend and When i put the timing belt on somehow it slipped and came loose I than tried to start it(not knowing it came loose) and it cranked hard and strong but no start. I just retimed the engine and put new timing belt set on it and when i started it the car blows grayish blackish smoke from the exhaust and has a really crazy idle. Could the valves be bent
The 1991 Acura Legend 3.2 is listed as an interference engine. (Other models that year if any probably not). If it is an interference engine the valves may have been bent. But asking y/a is not the answer. What you need is a compression test. If the compression is alright then there could still be damage but not in immediate need of repair. Black smoke means incomplete combustion.
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).
