- Q:she 13 and shes always sleeping what is a leaky valve there not telling me enough for me to understand and im a nurse tech im scared for her
- Leaky valve is generally refered to as back flow in mitral valve of the heart resulting into extreme debilitation and shortness of breath.Each heart beat sends blood leaking backwards through mitral valve making the heart work harder and harder to keep the blood circulating.No medication is available to treat or cure this condition.To correct the situation answer is either a mitral valve clip procedure or open heart surgery.
- Q:I want to put a blow off valve in my car to make it sound cool lol but i dont have a turbo yet ... do i even need one?
- A blow off valve is completely pointless without a turbocharger. Without a turbocharger, there is vacuum, not pressure in the air intake. There is no pressure to blow off therefore the valve will never operate. You would never get the sound that you are looking for. So the device would be completely pointless. It would not even look cool. When someone would see it, they would think. What idiot would put a turbocharger blow off valve on an engine without a turbocharger. So it would look stupid, not cool.
- Q:Friends,is there anyone know about LinX(Linear Exchage)Valve,how they work.thanks in advance
- A major improvement in the DWEER system has been the development of the LinX (LinearExchanger) valve, which was patented byShumway . This valve replaced eight two-way valves with asingle multi-port spool valve which simplifiedthe system, improved reliability, reducedmaintenance requirements and allowed for fastervalve switching, reducing the size (and thus cost)of the energy recovery vessels. DWEER systemsutilize long vessels which may be installed underthe membrane vessels. Atpresent, the largest available DWEER system has a capacity of 500 m?/h.

- Q:does it moves up and down with the valve stem??
- A poppet valve is a valve consisting of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem. The shaft guides the plug portion by sliding through a valve.. not sure if you are talking about tire valve stems? if so the poppet valve moves within the valve stem. I have also heard them referred to as Schrader valves see link
- Q:I know nothing about toliets - so please bare with me. The water valve underneath my toliet is dripping and I have to turn off the water in order for it to stop. It's really annoying to have to turn the water on when I want to flush it and have to empty out the container that is catching all the time. I think it has something to do with the valve itself and I'm PRETTY sure something behind it needs to be tightened - Has this happened to anyone else? What did you do?
- Hi. If the valve quits leaking when you turn it off and you are sure it has something to do with the valve then try this. Turn on the water fully until it is just snug and then look just under the handle for what is called a gland nut. The nut is to tighten a packing to prevent leaks. Tighten this nut until it is just 'firm'. Try not to overtighten this nut because you want to have the packing last as long as you can. Try several tightenings of the nut if it still leaks. If it does not stop the leak the valve will have to be replaced. It is a big hassle to replace the packing. I have done it before and it works ok in most experience. It is just a teflon impregnated string that you wrap around the stem after taking off the gland nut. Of course the water has to be turned off for this process. Hope this helps.
- Q:Our water heater (bought in 2007 so still fairly new still under warranty luckily) seems to release water from the pressure release valve quite frequently. Everyone seems to say that it shouldn't do it often and ours probably does it a couple times per day. 2 main questions - 1. Is there really a risk of too much pressure building up and the water heater exploding (that's what the sales guy at Lowe's said) and 2. Any idea what the problem might be/what we should check out?
- Don't let anyone foul you with this question because you have a bomb in your house and that pressure relief valve is telling you it's building pressure and when it builds enough pressure you will know. Since this is under warranty I would recommend calling a service tech out to look at it. It could be just the valve but generally they only pop off when they build up pressure. If it were just a leak I would say just the valve. Have you checked the temperature setting on the valve. Maybe it got moved up to a Higher setting. Or even better stay and watch the water heater go through a heating cycle. But don't take this lightly.

- Q:I was diagnosed with Mitral Valve Prolapse when I was 18. I am 23 now and feel like my symptoms have only gotten worse. Sometimes I could just be still and have severe chest pains with slight paralysis in my arms. It's like my body locks up from the pain. Recently I had an episode and I immediately started crying from 3 seconds of severe chest pain. For the past three days I've had this headache in my temples that sends a slight numbness down my jaw. I didn't know if these symptoms were in any way related to my MVP. I'm going to see the doctor today and plan on mentioning it. Does anyone have these same symptoms or an idea of what is wrong?Thank you!
- Although mitral valve prolapse is a lifelong disorder, many people with this condition never have symptoms. When diagnosed, people may be surprised to learn that they have a heart abnormality. When signs and symptoms do occur with mitral valve prolapse, it's typically because blood is leaking backward through the valve (regurgitation). Symptoms can vary widely from one person to another. They tend to be mild, develop gradually and may include: A racing or irregular heartbeat (arrhythmia) Dizziness, lightheadedness Difficulty breathing or shortness of breath, often when lying flat or during physical exertion Fatigue Chest pain that's not associated with a heart attack or coronary artery disease When your heart is working properly, the mitral valve closes during contraction of the left ventricle to prevent blood from flowing back into your heart's upper left chamber (left atrium). But in some people with MVP, the mitral valve malfunctions. In these people, the mitral valve leaflets are abnormal with extra tissue, bulging (prolapsing) like a parachute into their left atrium each time the heart contracts. The bulging may keep the valve from closing tightly. This may not cause problems if only a small amount of blood leaks back into the atrium. When blood leaks backwards through the valve, it's called mitral regurgitation (MR). MR can cause symptoms. Take care always! OIRAM
- 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
- Hey mechanic wannabe, The intake valve opens, the piston moving downward pulls the fuel mixture into the combustion chamber, the fuel explodes under pressure caused by the piston rising and both valves remain closed. When the piston comes back up the exhaust valve opens and all the burnt fuel leaves the combustion chamber and goes down the exhaust pipes until blown out the end of the exhaust system.
- Q:We live in a four story sixteen unity apartment building. There are two radiators in our apartment. The on in the living room is large and we can't turn it on with out water coming out of the little valve on the end, which I am assuming is there to release excess pressure. It doesn't matter if we leave it on for an hour or two days—water still comes out. It has warped the wood below it.How can I stop this? I would really like to have heat on both sides of my apartment.Thanks!
- Melvin S is correct. But check to see if the valve is closed first.
