Q: non-return valves: ..?..non-return valves..? I will assume that your 'non-return valves', are what is also known as check valves. Check valves allows flow in one direction only. These are used wherever you need to prevent backflow into the system, or to maintain a charged circuit with fluid, until you choose to unload(depressurize ) it. Now, why are they used in discharged lines of salt water, basically to prevent backflow....reason not known, here , requires usage info.

Q: large veins contain one way valves, which keep the blood flowing in one direction. why dont large arteries need similar valves?: The heart actively pumps blood forward. That keeps it moving in one direction. On the other hand, venous flow is more passive.

Q: I have 3 such valves in the line and none seem to be able to move past 10/4 oclock position and water remains on. Is there a way to adjust valve? Seems there is slot for screwdriver in center of valve.: The threads are stripped, you will have to get a new one, until then shut off main line into house if you are flooding

Q: Hey I'm high rite now and i have a checkup for mitro-valve prolapse tomrow, i was wondering if they will take my blood and see THC in me....: Mitral valve prolapse exams look more anatomically than physiologically. Meaning, they will take a picture of your heart instead of looking at the chemicals in your blood. BUT a prolapse may mean that your blood does not have enough oxygen in it because your heart circulation is abnormal, they may take a blood sample to test the level of oxygenated blood relative to deoxygenated blood to check this.

Q: 1990 Pontiac Sunbird 2.0L Fuel Injected has EGR Valve, I can suck and blow through the hose connected to it, an I supposed to be able to do this, or not...? It looks old, like it's been on the car forever...: It recirculates the fumes and the air--but a cracked hose is a nightmare if vacuum leak develops--fix it--just get a new hose and happy motoring

Q: How do you remove a richdel sprinkler valve, when I turn the body of it, it doesn't unscrew, it just turns in place.: is it the valve your trying to remove, or the sprinkler head? if its the valve, there will be two pipes, one in and one out, just unwind the thread at end end of the valve, If its the sprinkler itself, then there should be a pipe under the sprinkler(swing joint) just grab the whole body and unscrew ( make sure you grab the whole sprinkler and not just the top, you may have to dig around it

Q: I have a 2001 Ford Ranger with a 4.0 V6. I recently broke the valve cover bolt on the top right hand corner of the passenger valve cover ( the bolt closest to the belt). 1. Can I drive it like this and since 7 of the 8 bolts are in it should it leak worse. 2. How do I fix it, and 3. How much would this cost to have fixed if I took it somewhere. Thanks for your help: easiest to just remove the valve cover completely and then there might be enough of the broken bolt left to get a pair of vice grips on it and unscrew it out, go to parts store and get a new bolt and a new valve cover gasket and reinstall.If you drive the car the way it is it might leak a little oil around the broken bolt.

Q: Beneath my kitchen sink are two shut off valves for the water; one for hot, one for cold. The hot water valve has never successfully stopped all water flow, so we've always resorted to shutting off the main line. Well, now that's not working. We shut off the main water line to the house, all water everywhere is non-functioning except for the hot water pipe beneath my sink. It's now causing the faucet to constantly stream water, so it's something we have to resolve ASAP. I'd like to avoid calling a plumber, but my knowledge in such areas is very limited. Can anyone give me any decent suggestions? For the record, I did take apart the faucet fixture just in case, thoroughly cleaned it, and replaced all of the washers I had access to; but we only just bought the faucet in September, so I can't see a worn washer as being the problem. I also tried to tighten the nut behind the handle on the valve. It didn't effect the dripping.: Leaky Water Valve

Q: Please suggest some design or sketch giving details of its operation. I need to operate valves on a natural gas pipeline with actuators to sense and operate the valve after recieving the signals from level switch in the system. Please help me understand the mechanism and operation philosophy.Please also suggest your email address as I may have to revert for subsequent questions on the same. Your addresses will be safe here and won't be passed on to any undesired sites. Be rest assured.: This Site Might Help You. RE: How does a valve actuator work? Please suggest some design or sketch giving details of its operation. I need to operate valves on a natural gas pipeline with actuators to sense and operate the valve after recieving the signals from level switch in the system.

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.
