Q:I need to know how to use a valve spring compressor, the type that looks like a c-clamp. I understand the fork side goes on top of the spring and the circular side goes on the valve to push and hold. There are also two little scoop things in the middle of the fork that i don't know what they are used for. If i can get a step by step instruction, you will get the best answer

the scoop thing goes on the retainer or (the part that holds the spring in place) first there should be an adjustment on top of the tool where the fork is...put the compressor on the retainer..and adjust the screws until it fits tight on the retainer....then will have to adjust the bottom of the compressor where the handle is so that when you close the handle it pushes down the spring far enough to get the two keepers (two little half moon clips that hold the valve into the retainer....but first before you do anything...u must wear safety glasses if a keeper shoots out of there it may hit u in the face......after you put your glasses on and before you use the compressor take a hammer and hit the top of the retainer that u want to remove...DO NOT HIT THE TOP OF THE VALVE...it will damage the valve and you may end up needing a new one...hitting the retainer loosens the keepers so it will be easy to remove them....when you collapse the handle you can see the keepers in the retainer ..it may be help full to pull them out with a magnet..then slowly release the compassion with the handle and your done....this is hard to do at first and will require some practice to get good at it...be careful u can get hurt using this tool...i have been doing this for 30+ years so i have first hand exp. on both areas good luck

Q:I have the correct tools and have done this before. All I want to do is change all three valves that operate the water (hot,diverter,cold). The shower is leaking. I want to change all three valves to stop the leak. I will call a plumber if I can't change the valves or stop the leak. Please tell me what tools I need and I'll begin from there. I have three handles/valves in the shower(cold,diverter,hot).The cold is here # and the diverter is in the center which is here # and the hot is here #. They all line up like this c# diverter# h#. These are how the valves are set up # # #.

those 2 tabs are element of the cartridge. a clean cartridge comes with a disposable piece that fits in with those tabs and a sq. on the tip so which you would be able to turn and circulate it with a crescent wrench, which in turn loosens so it particularly is pulled out. possibly you ought to apply a robust needle nostril pliers to get it to tutor in case you probably did not desire to purchase the hot cylinder first. I believe utilising the plumbers grease once you're putting in the hot one.

Q:hii have just found out i have a genetic disease called multi valve prolapse but i want more info about itwhat are the symptoms? can it kill me? any info will help!!thank you

Do you mean Mitral valve prolapse? The mitral valve helps blood on the left side of the heart flow in one direction. It closes to keep blood from moving backwards when the heart beats (contracts). Mitral valve prolapse is the term used when the valve does not close properly. It can be caused by many different things. Most people have no symptoms, but some people have chest pain, a rapid pulse, awareness of heartbeats, migraine headaches, fatigue, and dizziness. In a small number of cases, the prolapse can cause blood to leak backwards. This is called mitral regurgitation. Mitral valves that are structurally abnormal can raise the risk for bacterial infection. Some forms of mitral valve prolapse seem to be passed down through families (inherited). Mitral valve prolapse has been associated with other genetic disorders.

Q:Hey my sexy internet homies lt;3: I need help on artificial valves. I need to know the following things:How do the properties of the materials artifical heart valves are made from make them useful?Explain how the structure of the technology is related to the function that it needs to perform.Thanks!!

There are three of these things: the caged-ball which utilizes a metal cage to house a metal ball, tilting-disc valves, which have a single circular occluder controlled by a metal strut. They are made of a metal ring covered by a tissue, into which the suture threads are stitched, in order to keep the valve in place once implanted and there's bileaflet valves, which consist of two semicircular leaflets that rotate about struts attached to the valve housing which is the most recent type, eh? So heart valves are considered to be extremely durable. They're made of either pyrolytic carbon or titanium coated with pyrolytic carbon, and the sewing ring cuff is Teflon or polyester or dracon (probably dacron :P). They key to the materials chosen is durability because of the constant fluid flow. I see this as pure engineering, not medicine, specifically fluid mechanics: like if there are rare complications for example thrombus formation is a debilitating side effect of high shear stresses created by design of the valves. Ideal heart valve from an engineering view would produce minimal pressure drops of course have small regurgitation volumes because it's supposed to minimize turbulence and regulate the flow.

Q:I had to replace the seat washers/stems etc in order for the constant drips from the kitchen faucet to stop. It did; but when i went under the sink to turn the water valves back on, the hot water valve felt as something inside it went smooth??? i can turn the hot water valve left and right but nothing is happening. No hot water at all from the kitchen faucet..Also there's low water pressure from the cold water that only came about when I tried to turn the hot water back on from the valve underneath the sink

Unfortunately most valves used today are made of plastic that only look like metal on the outside. Sounds to me like you and I live in the same house. I have to replace four different shut off valves because they are stripped. I am working on the kitchen one right now. Stripped Valve with no cold water and very little pressure in the other valve. If you ever have one replaced by a plumber, insist on all metal valves. I will physically inspect them from now on before they replace them. Once stripped nothing you can do but put a new one on.

Q:I wanna do it myself My dad knows how But i must buy the parts I have a rmz250 and i was wondering if u can jus buy valves and seals and jus put them in without grinding since the seals are new i heard u must gring the seals to get the valves to sit flush againt the metal serface but cant u jus buy new seals and retainers and put that in plus the valves and ur done?

It all depends upon the wear in the cylinders of the engine. Usually they are honed and made smooth again prior to installing the new rings, seals, etc.

Q:What are Atrial valves??

I've heard the term sometimes (though rarely) used instead of atrioventricular valves, the tricuspid (right) and bicuspid valves.

Q:difference between swing type check valve and non return valve? i need best answer... if swing valve will be opened when the fuel s reverse motion???

Non-return valve is another name for check valve. A swing check valve is just one type of check valve that uses a hinged gate to allow flow in only one direction. It operates sort of like a one-way fence gate, that you can open by pushing from one side, but you cannot open by pushing on the other side. Other types of check valves: Diaphragm, Ball, Lift, Duckbill. (:-o)

Q:i have been told that a bad EGR valve (exhaust gas recirculation valve) could cause a car to buck or hesitate in mid range speed at low rpms, thats what my car is doing. i work at autozone and i used our code reader and there was a code that stated EGR flow malfunction anyone else have this problem ever? please help me! i dont wanna spend the $120 if i dont need to!

to attempt the EGR valve operation, start up the engine and then disconnect the administration hose The EGR valve could open and engine could sluggish or hesitate. If disconnecting the hose makes no difference, the two the hose is leaky/ blocked or the EGR exhaust gas pipes are blocked. in case you intend on changing it your self spray it with wd 40 or a sturdy penitrating oil and enable it soak. and while reassembling it use an anti grab compound on the threads

Q:When my son was three I switched Dr's for him. The new doctor said has he always had a heart murmur I said no that's the first I've heard of it so we went for test. Anyway heart specialist did all tests said my son had Bav a valve disorder in the heart. He said it is very common. However everyone I've ever talked to has never heard of it. My question is does anyone have this what is your story and have you had to have your valve replaced. My son is very healthy active I'm just worried. Any help would be greatly appreciated....thank you!!

A bicuspid aortic valve is not necessarily a problem - a normal aortic valve has three cusps, and your son only has two. Having only two cusps is not a big deal. The mitral valve in the heart naturally has only two cusps, so three cusps are not needed for a heart valve to function. The advantage of three valves is a slight increase in efficiency, but the difference between a normal valve and properly working bicuspid valve would only matter to a professional athlete. If the aortic valve closes almost completely, there is nothing to worry about. Since he has a heart murmur, its possible that it is caused by having only two cusps, but people with three cusps commonly have murmurs. There is no reason to get the valve replaced simply because of only two cusps. What matters is the level of aortic valve regurgitation. If regurgitation is not significant, your son has a normally functioning heart. Even if he had a moderate or high amount of regurgitation, it still might not have enough effect to warrant surgery. There are tests to measure regurgitation.
