- Q: hey...im kinda confusedis cochlear an artificial valve???and if not..what is an artificial valve??
- Cochlear implants aren't valves, they're implanted behind the ears, they improve hearing in people who are hard of hearing. An artificial valve replaces a heart valve, which controls how much blood flows in and out of the heart.
- Q: wut is the purpose of this valve on tanks and on piping? explain wut the vacuum part does and wut pressure does? thanks
- The pressure relief valve is to protect a tank or piping from rupturing from excess pressure. A vacuum relief valve would prevent tanks and piping from collapsing from too little internal pressure.
- Q: Since the valve drain is usually open, I am wondering if placing the cap on the drain has made my water heater dangerous.
- To hold water in the tank your plastic drain valve should usually be closed. It does not matter if the water is held in the tank by a valve or a cap. A metal cap would be better than a plastic. You could also drain the tank and replace the gasket in the valve, but that is a lot of work for little benefit. Had not though of that. The drain valve is the one at the bottom of the tank. If this is a pressure relief valve, yes it would be very dangerous to cap it. The pressure relief valve is located near the top of the tank.
- Q: Are these valves are a kind of heart chambers pressure sensors?What is keeping them interlocked 2x2?
- It's all mechanical. The valves are passive things kind of like a screen door. When you push on them from one side they open, when you push on them from the other they close. The valves are assisted by some fibers attached to the inside of the heart similar to the way a screen door is helped by a spring attached to the door frame. It's the flowing blood that pushes the valves open or closed as the heart pumps. The path that the blood follows in the heart as it beats happens to make it so that the valves close two at a time. This is because the heart is actually four separate pumps that work two at a time. There's no direct electrical connection to the SA node. The only way they're connected is that the SA node firing is what causes the heart to pump, causing the blood to force the valves open.
- Q: It seems like the shutoff (stop) valve for the toilet is preventing my toilet tank from filling up for flushing. When I shut the valve, and open again, the water flows into the supply tube that flows into the tank for a few minutes. Afterward, the flow of water stops BEFORE filling the tank as if it lost pressure of water flow.I repeat the above (closing and opening valve) and does the same thing. (There is also no sign of leak...)What can I do? I'm hoping I don't have to call the plumber.
- Go to Lowe's, Home Depot, Ace Hardware, and buy a Fluid Master Complete kit. It is by far the best I have ever used in 6 houses, in 3 States.
- Q: Our reactor is cooled by a cooling water system. The line pressure is around 4 bars and the pipe size is 42. How to select a good valve for that service?
- Specialty valves should be sized/recommended by the manufacturer because of the different influences that may be encountered by the valve. Example: Temperature ranges, chemical composition of coolant, type of valve(ball, gate, tempering, other) all will have some effect. I would say take a look at the old one if it exists and if you're not satisfied with its performance, then cross reference it with other companies like Amtrol, Wilkins, etc. This would be the safest most logical method.
- Q: If this prolapse considered heart disease. I was diagnosed years ago with it . My doctor at the time told me this is not heart disease and now I googled it and it said this is heart disease. Another person said this is valve disease ? I never asked my current doctor if it was or not. She checks me every 3 months because I have a heart murmur that you can have with this prolapse. whenever I have filled out questionaires about health history when they ask me if I have heart disease I always check no. If this considered heart disease or valve disease. I've never been to a cardiologist for it. Should a person have at least one evaluation from a cardiologist for this ?
- Its a valve disease. It is a valve between the right atria and right ventricle within the heart muscle. Mitral valve prolapse simply is the fact that the valve does not completly close once the blood is pushed down from the atria where the deoxygenated blood is where the new oxygenated blood will be after it goes through the pulminart artery to collect oxygen from the lungs, then comes back to the ventricle. What then happens because of the prolapse is it has a little regurgitation, or spitting back up some fresh oxygenated blood back to the atria, and then continues to the left atria through the corniary vein. Hope that explains why its more of a valve disease than the heart disease. Heart disease has to deal with the heart muscle. And its chambers. Then you have corniary artery disease which focuses on the arteries and veins of the heart and of course the valves which includes your aorta, bicuspid (mitral valve), and your tricuspid.
- Q: I assembled my new gas grill, but I'm not sure if the burner pipes (aka venturi) are properly connected to the valves. My assembly matches the picture in the instruction manual, but I'm not sure if the seal is tight enough. How do I know? Do I attach the propane and test? I'm concerned about the safety of doing so. Thanks!
- Pipe Burner Venturi
- Q: So outside we have a gas grill. There is a valve to turn when you want to use it. U can only hear the gas going when u turn the burner knobs but say u left the valve open and no knobs turned at all for 5 hours is gas escaping or does it only escape when the grills knobs are turned? Thanks
- To answer your question directly, as long as the valve is open gas will continue to flow until its turned to the off position.
- Q: So my engine was back firing and me and my dad adjusted all my valves both sides. Runs better, But it still back fires. What could be the problem? Its a Chevy 350 with a brand new mild cam. 600cc carburetor. And new shorty exhaust headers. However I don't have exhaust pipes on my headers just yet because I gotta get pipes to mesh properly with my exhaust. Could it be air coming back up from the pipes causing it to back fire a bit? Like I said we just adjusted all the valves.
- Valves may be adjusted too tight. Run all the valves again but only add 1/3 to 1/2 turn after zero lash or when you can't rotate the pushrod with your fingertips.
