Q:Where can I buy a trigger valve?
Q:how many valves does a human heart have?
The four valves in the heart are: * The two atrioventricular (AV) valves, which are between the atria and the ventricles, are the mitral valve and the tricuspid valve. * The two semilunar (SL) valves, which are in the arteries leaving the heart, are the aortic valve and the pulmonary valve. Possible Complications:- * Arrhythmias (abnormal heart rhythms), including atrial fibrillation and lethal arrhythmias * Clots to other areas * Endocarditis (infection of the heart valve) * Heart failure * Pulmonary emboli (blood clots in the lungs) * Stroke
Q:Tricuspid valve leak normal values?
The tricuspid valve is a valve in your heart that, like any other valve, makes the blood flow in only one direction. When your heart pumps blood into your body, this valve is normally closed so the heart only pumps it in your arteries, and not back in your veins whence it came. When this valve doesn't close shut completely, a little quantity of blood leaks through the little opening there. You can see this with an echocardiography which you said you had done. Yes, the value of 19 is really low, and the fact that the limit to normality is 20, so you're close to it, doesn't mean that you're almost sick. Keep in mind that these limits that doctors have are some guidelines, and they all have a safe zone. Plus, this is not the kind of lesion that evolves, it doesn't mean that as the years go by the little space in your valve will get bigger and bigger - nothing of that sort. It is probably a thing that you had since forever, and you will have it the same your whole life with no problems at all. In the end, let me say that if you are brave enough to go to a doctor (many people aren't, and that really sucks), you should be brave enough to ask him/her what they mean when they say certain stuff, without worrying that your question might be stupid or already answered. You didn't go to med school, and it is the doctor's duty to explain to you what is happening in your body just as it is to diagnose and treat you. Best of luck!
Q:what is an oil pressure relief valve?
Oil Pressure Relief Valve
Q:Has anyone ever had Aortic Stenosis Valve Disorder or known anyone who has suffered from the condition and
There is a bloke just up the road from me had this procedure done about 3 years ago, and seems to be having a normal life. However, he is restricted on the use of strength. he was a carpenter / joiner which he has had to give up (He is in his mid 60's) Have you tried Wikipedia?
Q:PVC Ball Valve air rifle questions.?
These bike tire valves are called schrader valves i got mine from a car repair shop where they like had them for free. I mounted it into a pvc pipe by drilling a hole just big enough for the stem but there was a ball at the end that keeps it from falling out. Then to seal it you could you gorilla glue or epoxy to make it air tight
Q:What is the function of valves between atrium and ventricle?
the atrioventricular valves (AV valves) separates the atria from the ventricles. the AV valves perform a very important function in the heart by maintaining the blood flow in one direction. they are subjected to tremendous strain during every heart beat, and are uniquely designed to withstand this strain through a person’s lifetime. the right AV valves is called the tricuspid valve. the left AV valve is called the mitral valve. the opening and closing of the AV valves is dependent on pressure differences between the atria and ventricles. when the ventricles relax, atrial pressure exceeds ventricular pressure, the AV valves are pushed open and blood flows into the ventricles. however, when the ventricles contract, ventricular pressure exceeds atrial pressure causing the AV valves to snap shut. :)
Q:I was adding air to my bike tires and the valve became loose. Do I need a new tire or is there a way to tight?
The tyre should be fine, the problem is with the inner bike tube. It is useful to know what type of valve your bike tube uses. Schrader valves have a middle pin surrounded by an outer ring. Presta valves have a movable nut that allows you to inflate or deflate the tube. It sounds like your bike tube has a presta valve you have damaged the movable nut by loosening it a bit too much and/or being a bit too rough with it when using the bike pump. Unfortunately, it can't be fixed. If that is the case, you will need to buy a new bike tube (and keep a spare one handy as well) edit - That's weird, Schrader valves don't usually do that. It must have been an old tube or a faulty one. You'll be needing a new bike tube. edit - Well, I didn't know you could fix them, but still it'll be less hassle if you just brought another tube.
Q:How to remove the valve springs on a1991 jaguar xj6?
Do NOT do what banit said, if you did his technique once you remove the keepers the valve would drop to the bottom of the cylinder and require a tear down. You must get the piston be at top dead center on the cylinder you intend on removing the valve springs from and you cannot do any other valves besides the ones on the cylinder you brought to top dead center. You can take the rocker arm off the top and take the push rod out then when at top dead center using a spring compressor you can take the keepers out, or if you do not have a spring compressor (proceed at your own risk) you can get an oversized socket and a dead blow hammer and place the socket over the top of the valve spring with the octagonal side towards the spring and give it a decent hit, but be aware the keepers will pop out and you may lose them if you are not careful.
Q:Valve cover oil leak?
Sounds like you should clean your engine, then take a look to see where the leak is. Have you tried tightening the valve cover bolts?.
