Q:used in pipe line: Bellows Relief Valve

Q:I'm drawing a complete diagram of the heart, but I'm unsure of the positions of the different valves. I know there are the pulmoary valve, the aortic valve, tricuspid/right AV, bicuspid/left AV, semilunar valves, mitral...but I know there are several names for some of them, like I think the mitral and the bicuspid are the same...but there are so many sources online I don't know which to believe. If anyone knows for absolute sure the right names and where they are it would be very appreciated if you could help :): the bicuspid is the same as the mitral valve it seems like anatomy has 12 names for everything In anatomy, the heart valves maintain the unidirectional flow of blood in the heart by opening and closing depending on the difference in pressure on each side. They are mechanically similar to reed valves. There are four valves in the heart (not counting the valve of the coronary sinus, and the valve of the inferior vena cava): The two atrioventricular (AV) valves between the atria and the ventricles, also called tricuspid and bicuspid. The two semilunar (SL) valves, in the arteries leaving the heart, also called pulmonary and aortic. This I know for sure. Drawing pictures always helped me keep it straight and I just got an A in anatomy. best of luck to you

Q:What is the easiest and best way to fix a leaking shut-off valve on a toilet?: Take out the old one. it is easy it just slides up the over flow tube go to a hardware store and get a replacement ball valve (Ballcock) they are just a couple bucks.slide the new one on! Take the old one when you go to get the new one.

Q:The atrioventricular valves will be open whenA. Atria are in diastole and ventricles are in systole B. Pressure in the ventricles is greater than the pressure in the great arteries C. The ventricles are being passively filled D. The ventricles are in isovolumetric contraction: C. When the ventricles are being passively filled, the valves between the atria and ventricles (atrioventricular valves) will need to open. When pressure in the ventricles is higher than in the arteries, blood will flow into the arteries - there is blood exiting the ventricles, so the ventricles are contracting, so the atrioventricular valves need to be closed to stop backflow of blood into the atria. When atria are in diastole (filling) and ventricles are in systoles (emptying), the situation is the same as I just described for B.

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. DWEER (Dual Work Exchanger EnergyRecovery)

Q:I replaced the valve cover seal and I wanted to know the torque specs for the valve cover bolts and the sequence it should go: A followup question... if I have already tightened the valve cover down, most likely to the incorrect torque, then drove it around for a couple of miles then let it sit for a week. Will I be able to go back and loosen the valve cover then re-tighten them to torque specs or do I need to start with new gaskets? No sealant used. The gasket was the metal and rubber combo type.

Q:why is a biological valve replacement weak? in the way it does not last much longer that ten years?why do blood clots form with a mechanical valve replacement?what kind of bleeding problem can the anticoagulant medication cause?if you know the answer to any of these questions (doesnt hav to be all of them) plz answer!! thank you :p: why is a biological valve replacement weak? in the way it does not last much longer that ten years? --- Its not weak its just that it can fail like the original valve did. Most Doctors prefer to use a mechanical valve(such as titanium) because there is a lot less changes that it will fail and the surgery will have to be repeated. The St. Jude valve is one that is comonly used by doctors(thats the one I have in my heart) Mechanical valves make a ticking sound(kind of like a watch) as your heart pumps blood, this can accually be heard when your next to a person with one in a quiet place(I've freaked some pople out when they heard mine). why do blood clots form with a mechanical valve replacement? --- Blood can clot around anything that is foreign in the body, its part of the human body's natural defenses. what kind of bleeding problem can the anticoagulant medication cause? --- anticoagulants(or blood thinners) do not really cause bleeding problems as long as you have your INR monitored and controlled. those people on anticoagulants(such as Comadin) may bleed a little longer then someone not on them. a person on anticoagulants may bruise easier then someone not on them and the bruise may last a little longer. They bleed a little more but its usually not anything to worry about. A person on blood thiners may also feel colder more often due to the thin blood. Diet can also affect anticoagulents, foods such as leafy greens, alcohol, all affect these medications. Leafy Greens are high in vitaman K wich thinkens the blood. Alcohol thins your blood.

Q:also are those air flow limiting valves safe for the air pump to reduce the flow of air, I have one because the air bubbles are just way too many without one and it scares the fish away: a check valve is to prevent back siphoning of water into the pump if you have a power outage or unplug the pump by accident. I'd suggest checking it by blowing through it the wrong way; if air does pass through get a new check valve (check new ones to be sure they don't limit airflow too much, and that the close in the wrong direction, many are cheap crap and don't work the day you buy them, so check them before you leave the store with it...note: same with thermometers, compare them with each other so you don't get the one that's crap) what you want is a normal air valve, they come in various configurations, one or more valves so as to run multiple airstones and to balance the airflow to each stone or ornament. You should not however just use the valve to limit airflow, as this damages the pump eventually. You can just let one of two valves bleed off a little air; however make sure another check valve is in the line from the tank to the valves or else you risk water coming out of that valve if it's lower than the tank water level.....You may want a smaller air pump or an adjustable one instead.

Q:List all the brass instruments with valves? Thanks. I need it for the history exam -.-: Keys are metallic disks with pads (leather-based-lined, padded products) under them, that are pushed all the way down to close a hollow in a woodwind device. Valves are merely like hydraulic valves: they are mechanisms which flow somewhat (a piston or rotor) to alter the path of airflow via tubing. present day brass gadgets use valves. They paintings with the help of fixing the dimensions of the brass tubing (with the help of switching in extra beneficial lengths) to alter the pitch-length of the entire device. There are 2 brass-mouthpiece gadgets which survived far adequate into the classical era that they are nonetheless utilized in present day overall performance, the Serpent and the ophicleide. (the former is formed in s-curves, subsequently the call, the latter is a relative of the Russian Bassoon, that's additionally a brass-mouthpiece device.) those are keyed. between the 1st efforts to apply something different than a slide to alter the pitch of a brass device (slides as in trombone) replaced into referred to as the keyed bugle, because of the fact it had great keys on the aspects of the conic-bore tubing. it is not believed to have been a fulfillment, and is not used as we talk. So, for present day gadgets, brasses use valves, woodwinds use keys.

Q:what are the factors should be know to select a control valve for specified application: control valve is an uni-directional (non-return) valve, some of the factors to be aware of before selecting it....identify application character, select the valve size, select the valve end connection, piping layout and valve orientation , maintenance requirement , actuation requirement , initial cost ..etc..
