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!!
There is a cut off valve at the water meter.Before you get to deep in this,make sure the water is not running down the line from the tank it self.Dry the line coming out the tank with a paper towel just to make sure it is the valve leaking.Believe me,it can fool you.
Q:give some application of varible throttle valve?
A throttle valve allows continuous control of the rate at which some fluid moves from a region of relatively high pressure into a region of relatively low pressure. An example would be in an automobile engine, where the throttle controls the rate at which air (at or above atmospheric pressure) enters the engine's intake manifold (near vacuum when the throttle is closed.) The throttle in an automobile engine is mechanically linked to the gas pedal (in case you didn't know).
Q:Was wondering if there is something I could purchase to put into a car so that it will become a 24 valve????
Time to drop out of your software then. You did no longer even attempt - you in basic terms decrease and paste an common quiz devoid of even inclusive of the linked diagrams, and anticipate us to unravel it. Why could we do this? you haven't any longer even attempted. i do no longer want you getting close to a motor vehicle in any technical means in any admire in case you could no longer answer those questions.
Q:My mother was dx'd with Mitral Valve Prolaspe 20 years ago....she use to take meds for it. My question is she is having very bad fatique symptoms.. uld this be caused from her MVP getting worse???
I would say she is probably due for a check up. She probably will need an echocardiogram of her heart to check the mvp
Q:I have a 2004 yfz 450 and in the passed 4 rides (about 2 hours long each), one of my valves has stayed down and been broken when the piston came back up and made contact with it. After putting it back together the first time i checked numerous times to make sure timing, valve movement, and camshaft movement were all correct. and just 2 rides later (today) the same thing happened again. I have not began work on it yet so i do not know if it is the same valve. But has anyone ever had this problem before? Is this something frequent with yfz's or am i missing an important maintence issue? And can anyone tell me why this is happening? All help and tips are much appreciated!! Thanks!!
Valve guides wear and get loose, so the valve stem binding up in them is highly unlikely. If the guides are shot, they should be replaceable. Sometimes valve stems warp and will cause your problem, but the odds of it happening a second time are also unlikely. Once you tear into it, I guess the deciding factor will be if it's the same valve or a different one. When this happened, were your rpm's high or otherwise? I ask because if when high, I'd check for a broken or weak valve spring/s. Most have one spring inside of another to reduce harmonic vibrations and if the inside is broken, not only will you not have adequate spring resistance for high rpm running, but at a certain rpm the remaining spring will be quivering like a dog pooping peach seeds. The other thing that may have happened is the camchain tensioner isn't locking tightly. If so, that would let the chain jump a tooth or two and then Mr. Piston and Mr. Valve get into hand to hand combat. The old 6 cylinder Kawasakis were well known for having crappy tensioners that would do just that. However, with them, it usually happened during startup. Or, you may have had a camchain guide fail and with it laying in the bottom of the oil pan,the tensioner isn't able to take up all the slack in the chain. When you get it apart, let us know what you find because I suspect you need to be looking for the cause of the bent valve somewhere else than the valve itself.
Q:i have a 05 kx250f, new valves recently,will pop start, idle runs high, has compresion, new kckstarter gear but it wont kickstart. someone said the valves need to be shimmed.anybody have any ideals? thanks.

Q:We've got a one-handled faucet for the tub/shower and it has that pressure-balancing mechanism. We have it set, I think, so that we can take the hottest showers possible, because our water heater lacks enthusiasm. However, when I want to draw a bath for the baby, I need it to be lukewarm - and I have to turn it almost OFF to get the water to be even tepid. I can't get cold water out unless it's only trickling. As far as I can tell, our cold water pressure isn't different from the hot (bathroom faucets are 2 handles and H C seem to be about the same pressure). Is there a way to adjust the valve in the shower so I can get both the hottest possible, and the coldest possible water at full pressure?
the new single handle tub and shower valves all come with a scald guard mechanism.(its code so kids cant turn on the hot and burn themselves). take the handle off and mess with it. it will be grey or black with a bunch of grooves on the outside. keep adjusting it till it satisfies you.
Q:i have a valve seat pop out and it did some damage my question is can it be fixed i took it to a machine shop the guy look at me with a little confusion he said it cant be done anyone out there have another answer
It depends on the amount of damage. Before they relocated the oil cooler it blocked airflow to one cylinder and the exhaust valve ran hot. The valve guide wore, the valve started hitting the seat off center and the valve head would break off to bounce around inside the cylinder, often putting a hole in the top of the piston and dropping debris into the case. The cheapest solution was to find a used motor to put in. If there's no damage to the piston, you might be able to repair the head but that valve bouncing around usually does a fair amount of damage.
Q:what's the function of a car valve???????????
It is the stopper for the combustion chamber, the intake one lets stuff in and the exhaust one lets stuff out.
Q:I just found out about my condition. Is it dangerous? And will I need surgery? My mom just got her monocuspid valve replaced. I don't wanna have to go through the same thing. And will I still be able to go on rollercoasters? I'm going to cedar point tomorrow. I only want answers from people who know exactly what there talking about thanks
so, as you already know, a typical aortic valve has three cusps. yours has two, so this is a structural issue. the point of these cusps, or leaflets, is to maintain blood flow in the appropriate direction through the heart and to the rest of the body. having a bicuspid aortic valve can be something that you inherit from one of your parents. did you have a murmur that prompted them to look for it? if your valves are young and healthy, there's probably not a problem. when it can become problematic is with age, where the leaflets can become calcified and hard, then they can not open as well (i.e. become stenotic), or not close properly (i.e. become regurgitant). if either of these two things develops, and becomes bad enough, they consider valve replacement surgery. but this is the kind of stuff that happens over years and years. you should see a cardiologist, if you haven't already been referred to one, because this is a medical condition that gets watched over time, and then if it gets bad, it gets treated. while it's not bad, it gets watched. this cardiologist will follow you over time, in addition to your regular family physician. he/she will also be keeping an eye on your aorta (the big vessel that blood enters after it goes through the aortic valve), because sometimes people who have bicuspid aortic valves also have problems with your aorta. i would also talk to your cardiologist about whether or not you need to take antibiotics in advance (i.e. prophylactically) of any dental work. i.e. because of your valve with a different shape, are you more predisposed than the average person to getting an infection there. but go to cedar point if you're young and healthy. a roller coaster should not give you any sort of problems. enjoy yourself!
