Q: I got an engine knock and backifiring and no power not even to move the car just a few feet. I figured its the vales that are eather broken or burned out. I just started to take my top end apart to check and change borken or damaged valves so i can drive the car once again. My question is, when i take the valve cover off i can see what looks like the valves and the springs and something in the middle of the springs, now what iam i gona be looking at for a broken/damaged valve since i dont see any obvious damages but i could be wrong.: take it in.

Q: Can you please explain to me what an atrial valve is and what it does??: You're incorrectly combining two parts of the human heart, atrium(atria) and valves. The human heart has four chambers, two superior ATRIA and two inferior ventricles. The atria are the receiving chambers and the ventricles are the discharging chambers. The pathway of blood through the human heart consists of a pulmonary circuit and a systemic circuit. Blood flows through the heart in one direction, from the atria to the ventricles, and out of the great arteries, or the aorta for example. This is done by four VALVES which are the tricuspid valve, the mitral valve, the aortic valve, and the pulmonary valve

Q: Situation: The males in my family have mitral valve prolapse, while I do not.If anyone could answer some of the following questions, it would be amazing! Thank you so much!1. Is this an X or Y chromosome disease? (I thought since it was just guys, it'd b Y)2. If so (or not), is there any reason why I don't have it?Thanks again! (:: Dear Madam, I am a cardiologist sending this article for you. Hope it helps you. Mitral valve prolapse, sometimes called MVP, is a common heart valve disorder. The mitral valve is between the left atrium and the left ventricle of the heart. It has two leaflets (flaps) that control the blood flow. MVP occurs when one or both of the leaflets are enlarged or have extra tissue. MVP is usually harmless. However, major complications can occur, including a blood clot in the brain and an infection called infective endocarditis involving the mitral valve as well as other valves. MVP appears twice as often in women as in men. It is most commonly a hereditary disorder. Some people with MVP have no symptoms. However, most patients experience a rapid or irregular heartbeat, shortness of breath, light-headedness, and chronic fatigue. Many patients also suffer from migraines, eating and sleeping disorders, an overactive or inflamed thyroid gland, diarrhea, and cold hands and feet. Emotional stress often magnifies the symptoms. Doctors generally prescribe regular exams and aerobic exercise for people who have MVP. Patients also are advised to restrict their intake or use of high-carbohydrate foods, caffeine, and decongestants. Some patients may need beta-blockers and specific antiarrhythmic medication. More severe cases may require surgery to repair or replace the valve or to insert an electronic regulator, such as a pacemaker or defibrillator.

Q: where is the bleed valve in a 97 taurus????thank you: remove or loose radiator cap crank motor top off radaitor and over flow jug crank motor with cap off either way crank motor let run air will come out if cap is loose or off and it dont get air trap unless its been apart such as a hose replace or coolant drained type into search box how to fill a radiator how to check a overheating car how to check engine coolant how to replace engine coolant how to bleed air out of radiator

Q: my valves got dirty long story how do you clean them: Remove the valves, wash them and the horn in warm (NOT hot) water with liquid dish soap. Dry with a clean towel, then oil and reassemble.

Q: Our reactor is cooled by a cooling water system. The line pressure is around 4 bars and the pipe size is 42. How to select a good valve for that service?: You'd also need to know design flow ranges, ultimate flow desired, pressure drop acceptable across valve, and the average temperature of cooling water the valve will see or the range it will see if varies much. You would need to decide if you want to use a ball valve, butterfly valve, of a globe valve to throttle the water.

Q: hi guys..What is different between globe valve and stop check globe? Is that stop check globe=SDNR JIS std?: I am not even sure what you are talking about. a globe valve is a type of valve that can stop the flow by turn a handel on top of the valve. A check valve on let the flow go one way and stops the flow the other way. hope this help Globe valve From Wikipedia, the free encyclopedia Jump to: navigation, search A Globe valve is a device (specifically a type of valve) for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.[1] Globe Valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug[2] can be screwed in to close (or shut) the valve. The plug is also called a disc or disk.[3][4][5] In globe valves, the plug is connected to a stem which is operated by screw action in manual valves. Typically, automated valves use sliding stems. Automated globe valves have a smooth stem rather than threaded and are opened and closed by an actuator assembly. When a globe valve is manually operated, the stem is turned by a handwheel. Although globe valves in the past had the spherical bodies which gave them their name, many modern globe valves do not have much of a spherical shape. However, the term globe valve is still often used for valves that have such an internal mechanism. In plumbing, valves with such a mechanism are also often called stop valves since they don't have the global appearance, but the term stop valve may refer to valves which are used to stop flow even when they have other mechanisms or designs. Globe valves are used for applications requiring throttling and frequent operation. For example, globe valves or valves with a similar mechanism may be used as sampling valves, which are normally shut except when liquid samples are being taken. Since the baffle restricts flow, they're not recommended where full, unobstructed flow is required.

Q: Ok. I have to ask cause I have been in hospital all weekend after having a moment on saturday when my heart decided to start racing. Woke up 4.30am on saturday morning cause of blood test which kinda showed I could have had a heart attack which was scarey and though I was discharged today I got told I had a leaking aortic valve. What does this mean and what is going to happen. I am honestly really worried cause it cant be good: It just means that one of the valves in your heart doesn't completely close. So when your heart pumps blood it doesn't do it as effectively. I have a leaky mitral valve and I have no symptoms. I just have to take antibiotics anytime I have dental work done. Bacteria from your mouth like to mess up your valves if they are already leaky. But it almost never happens. It's just a precaution. You really need to talk to your doctor about what he found. He needs to explain whether it's serious or nothing to be worried about.

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: I have a problem with standing water that keeps puddling up and never drains under where my valves are located for my sprinklers. What do I do? Should I just put 3/4 drain rock on top? Please help?: Sounds to me, like you have one of two things happening. Either you have a leak, which needs to be fixed. Or the valve box is in a low area where the water drains to... Turn on the water and watch the valves.. you might be able to see where the water is coming from. It may be as simple as tightening down the valve screws, or you may need to turn off the water at the main and repair or replace it. If the water is draining there or the leak isn't all that terrible the only way drain rock would help is if you were to dig underneath the valve a little, and to replace what you dig out with rock... Just make sure you can still access everything when you are finished. Good Luck!
