Q:The tricuspid valve is closed: a. during the rapid filling of the ventriclesb. when the mitral valve is openc. during ejection of blood from the ventriclesHelp plzThank you!: The tricuspid valve is the connection between the right atrium and the right ventricle, so when blood is rapidly flowing from the RA to the RV, the tricuspid must be open, so it's not A. The tricuspid and the mitral valve open simultaneously so it's not B. As the RV contracts to eject the blood from its chamber to the pulmonary artery, the pressure created within the chamber closes the tricuspid valve to prevent the blood from flowing back to the R Atrium, so the answer is C.

Q:Hi, I was told by my gardener that I need new sprinkler valves and each of those run about $50-70. I looked up online and I found them for $20 or less. Also what is the basic labor cost for getting them installed? I got estimates that range from $300-1000. I am confused.: they screw in and out, acouple of wrenches, a shovel, a roll of teflon tape, all less than 300$

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:Valves regarding WC's: The proper names of the two valves in a typical home toilet are the flapper valve and the ballcock valve. The flapper valve sends water from the tank to the bowl during the flushing of the toilet. The ballcock refills the tank and also sends a small amount of water to the bowl during the flush.

Q:I got a '99 bmw 740il that is leaking and burning oil. It shoots smoke out the exhaust when i first start it from burning oil. And the car misfires when idling, i did a tune up and the spark plugs were soaked in oil causing the tune up not to help anything for long cause it was missfiring the next day. Does this sound like the valve stem seals? I bought new valve cover gaskets and grommets and im gonna replace those this weekend, im hoping that will help. Comments please: Bad okorder /

Q:Where is the mixer valve on a '94 Dodge Caravan with a 3.0 V6 engine?: which valve are you talking about,fuel injection is mixed automatically with the air and fuel ratio through the injectors,i hope that was what your talking about,good luck.,,PS i don't think a 94 model uses a mixing valve,if it does have one on it it will be before it goes in to the firewall in plain site.

Q:We have an ejector in the basement for an in-law apartment. When the check valve kicks in, it can wake us up from a sound sleep. A very loud thunking. Any ideas?: the check valve would be installed just outside of the crock vertically. The noise I doubt is from the check valve itself. I'd guess it is the pump shutting off and the pipe isn't fastened securely, so it bangs. Check to make sure that the run of pipe leaving the crock is fastened securely. if this is the case the only other option I oculd think of would be to re-position the check valve on a horizontal run of pipe as close to the crock as possible. Most check valves I have seen for ejectors are compression type, it will be messy but not to complicated. Keep a bucket handy, when you crack open that check valve you may need it. Flush the toilet until the pump kicks on a few times, this should clear out most of the nasty stuff. You may also need a short piece of 2 pipe and some couplings to make up for the space of the check valve. If you can hear the water flowing out when the pump kicks on and don't hear it draining back into the crock when it shuts off, the check valve is probably still good.

Q:I have a Jupiter double horn. The thumb valve will randomly stick down and not want to come back up. It however only does this when I play a scale or am in the middle of a song, so when I ask the director or an instrument repair person to help, they think I'm crazy and see nothing wrong with it. Also, the first valve is slightly bent sideways towards the second valve. I got it used and it came like this. It is not horrible, but that makes it significantly slower than the other valves and sticks a LOT. All repair shops do is take my money and claim they've fixed it when they have done nothing. It is so frustrating. What should I do? And the oil doesn't help with either of these things, which is even MORE frustrating.: Open up the #4 valve cap and flood the top with valve oil, put the cap back on and turn the instrument over. Put valve oil in the crack where the valve comes out of the bottom of the valve case. This can be hard to see. Put some drops on every moving part of the valve action. I can remember the layout of that valve but I don't think you can shoot oil into the valve. Try all that I said above and see if that helps. Rotate and wiggle the valve between each step.

Q:The pig heart is better than our heart but the valves can be used to help us.: I have had heart surgery and they ruled out replacing my valve with a pig valve because they only last about 5 years. They replaced mine with a mechanical valve, and so far it's amazing! If they replace your valve I believe they basically cut out the defective one and sew in a new valve, animal or man made. If replaced with a pig valve you must be on anti-rejection medicine, and have it replaced every five years or so. With a mechanical one you have to be on blood thinners, but they assume (last I heard) they should last a minimum of 40 years, probably longer.

Q:I am trying to repalce the water turnoof valve under my sink but the valve just keeps turning and no progress is made to get it off so I can put on a new one. I am turning it clockwise but it just keeps turning. Can someone please tell me how to get this off? I do not want to have to call a plumber for something that I might be able to fix myself.Thanks.Sandy: basically component to the diverter valve is broken, besides the undeniable fact that, it extremely is terrific to replace to total diverter stem. If their are 3 handles, you are able to do away with the middle one devoid of turning the water off. Then convey total stem with you to the ironmongery shop. There are quite some video clips on youtube and different ironmongery shop factors of interest in case you like help. good success.
