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:
1、The 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:It looks like our toilet water shut off valve is leaking. We are trying to turn off the water by turning the lever on the hot water heater, but this only turned off the hot water. So the cold water is still not turned off? We thought the one lever at the hot water heater would turn it all off, but it didn't work. Is there actually a separate water shut off valve for cold water in my house? Help!!
- The water shut off valve is located where the pipe enters the house from the city water main. Maybe on the outside wall of your house near an outside faucet. Or maybe in the ground under a cover plate near an outside faucet, or maybe in the basement near where the pipe comes into the house from outside. There is also ususally a valve out at the water meter. The valve at the hot water heater just shuts of the cold water supply to the hot water heater, so it only effects the hot water.
- Q:A friend of mine who is 26, was just told by her doctor that she has aenlarged heart valve. Is this really serious? Will she need surgery? Why can't I find any info on the internet? Please help I'm really worried. Thanks
- there are two valves in the heart, a bicuspid valve (two flaps) and a tricuspid valve (three flaps). A valve serves to prevent the back flow of blood in the heart, keeps it all flowing in one direction. An enlarged or incompetent valve would obviously be unable to do it's work properly. How serious the issue is depends entirely on the extent of enlargement. Enlargement is usually a result of uncontrolled blood pressure issues, but can also be genetic. As she is seeing a doctor about this, suggest that you let the doctor worry about it.
- Q:1. Why is there an exaust valve. Isnt it only a port. Where do the gases that go into the exaust valve go?2. How does air enter the intake valve. If you look at a push rod diagram, you cant see where the air is enteringCan someone explain to me the valve concept
- The camshaft is turned by the crank shaft and is in time with it. the cam shaft either pushes the valves open and closed or pushes on lifters or pushrods that drive the rocker assemblies that move the valves. On a two cycle engine yes under most circumstances the exhaust valve is only a port. On a 4 cycle engine like on a vehicle it has exhaust and intake valves. When the piston is on the exhaust stroke the exhaust valve is pushed open, the piston comes up and pushes the exhaust gas out through the open valve, near the top of the piston stroke the intake valve begins to open as well and for a very brief moment both valves are open this is known as valve overlap. This allows incoming air to help expel the burnt exhaust gas. The exhaust gas goes out through the exhaust port through the exhaust piping and into the air. When an engine is running or cranking (pistons moving) it creates a natural vacuum which draws in air, when the intake valves open air is drawn into the combustion chamber pretty simple. Then the air is mixed with fuel vapor and when the piston comes up on the compression stroke the spark plug fires and the air fuel mix burns and drives the piston down. The valves allow the engine (AKA some call it an air pump) to work and pump air. Without them the pistons would do nothing absolutely nothing.
- Q:Okay, so when I was little, I had heart surgeyue to a congentital heart defect and I now have a leeky valve, on my aortic valve and i was wondering if it didnt go away would I need to get heart surgery? Or would it need to get bigger?Will it only get bigger or will it alwayse same? If I need heart surgery how long would that be??? have had it since 3rd or 4th grade and I am now in 8th grade. I am just wondering...
- Valvar insufficiency/regurgitation that is a result of surgical repair of a congenital defect does not self-resolve. It's not clear what your initial diagnosis was, however I would guess that you were born with aortic stenosis. Balloon enlargement and/or surgery to repair a stenotic valve almost always results in some degree of insufficiency/regurgitation. A small amount of insufficiency/regurgitation is much better tolerated than stenosis. It is a tradeoff we accept for improved patient outcomes. Really, the answer to your question is dependent on a multitude of factors, the most important of which is the degree of insufficiency/regurgitation you have (i.e. trivial, mild, moderate, or severe). This is really a great question and you deserve a full explanation. However, I cannot give you a factual answer without more information. You may also have a bicuspid aortic valve, which opens up a whole other set of variables. One thing I am sure of, however, is that you will require the care of a cardiologist for the rest of your life. It's possible that later on you may only have to follow-up ever 1-3 years, however, it will forever be necessary to properly monitor your valve and its effect on your heart, not to mention any associated problems you may not be aware of that become a risk with age. Good luck.
- Q:Okay, so veins have valves to help counteract the pull of gravity. I'm wondering, do the veins in the head have this same adaptation, seeing as these veins are simply bringing blood down to the heart, and are not pulling against gravity.
- no
- Q:I was diagnosed by 2 places that my 1995 chevy lumina needed a new egr valve due to the check engine light being on. I got a new EGR valve but the check engine light is still on. Evidently there is something else wrong with the car. Since the check engine light is still on would you figure that my EGR valve is still good and that the light comes on for some other problem?
- i think your right. I'm not sure but a think your EGR valve is vacuum operated. If so, there is a vacuum solenoid to control the vacuum to the egr valve. There is also intake vacuum to this solenoid. Could be no vacuum to solenoid or a bad solenoid or wires controlling the solenoid. But also could be a completly different problem other than egr. You need to go back to the shop that put on the egr valve and find out why the egr valve didnt fix your problem. And either have them fix it right or get your money back.
- Q:emission control valve toyota camry
- Is English your first language? Where is the question?
- Q:I saw some other answers. I figure the relief valve needs replacing, ok no problem, but exactly how much pressure are we talking about here? what is the correct procedure to shut this thing down to replace the valve?
- You have already done what you are supposed to do. My only thought is that the thermostat on the heater is bad. I have installed hundreds of State heaters and the only problems I have ever had was a bad thermostat. Good luck. :) But be sure that you have an expansion tank on the heater. I forgot to mention that earlier. 70 PSI is higher than normal, but perfectly acceptable. I always have my house at 70 psi and no problems (also a State heater). I have a 50 gal heater.....I am not as rich as you are....LOL
- Q:How do you clean an EGR valve on a 1999 Ford Taurus DOHC? What do I do and what can I use? Will water work? I've read a lot about a plunger mechanism but I have no idea what this is. Please explain in the best detail you can how to remove, clean, and re install the EGR valve?
- you don,t want to use water. the way i clean mine on my oldsmobile is i take it off and take a rag and some carburator cleaner and clean the bottom off where those little pintals are at. make sure the pintals work back and forth without sticking.
- Q:my mechanic did a valve clearance check and said it was OK and when I asked him about the clearances he said that they were 6 thousands and 9 thousands however in my book the measurements are different they are as follow: ( i don't understand what he meant by thousands)inlet: 0.10~0.140.15~0.19 exhaust: 0.14~0.190.20~0.24so did he just make it up or did he get the wrong measurement.
