Q: How many kinds of butterfly valves are there?: Also known as butterfly valve, control valve has a simple structure, can be used for low pressure pipeline valve switching control is closed parts (disc or disc) is a disk, around the valve axis to achieve the opening and closing a valve, the valve can be used to control the flow of air, water, steam steam, all kinds of corrosive medium, mud, oil, metals and radioactive liquid media and other types of fluid. On the pipeline, mainly from cutting and throttling. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.[structure]The utility model is mainly composed of a valve body, a valve stem, a butterfly plate and a sealing ring. The valve body is cylindrical and has short axial length and is internally provided with a butterfly plate.

Q: I am confused as to the answer of this question. Please help.Indicate the status of the mitral, tricuspid and semilunar valves (whether they are open or closd) during the various phases of the cardiac cycle. Discuss the pressure in each of the relevant chambers or blood vessels during the phases with reference to the opening or closing of the valves.: A heartbeat is a two-part pumping action that takes about a second. As blood collects in the upper chambers (the right and left atria), the heart's natural pacemaker (the SA node) sends out an electrical signal that causes the atria to contract. This contraction pushes blood through the tricuspid and mitral valves into the resting lower chambers (the right and left ventricles). This part of the two-part pumping phase (the longer of the two) is called diastole. The second part of the pumping phase begins when the ventricles are full of blood. The electrical signals from the SA node travel along a pathway of cells to the ventricles, causing them to contract. This is called systole. As the tricuspid and mitral valves shut tight to prevent a back flow of blood, the pulmonary and aortic valves are pushed open. While blood is pushed from the right ventricle into the lungs to pick up oxygen, oxygen-rich blood flows from the left ventricle to the heart and other parts of the body. After blood moves into the pulmonary artery and the aorta, the ventricles relax, and the pulmonary and aortic valves close. The lower pressure in the ventricles causes the tricuspid and mitral valves to open, and the cycle begins again. This series of contractions is repeated over and over again, increasing during times of exertion and decreasing while you are at rest. The heart normally beats about 60 to 80 times a minute when you are at rest, but this can vary. As you get older, your resting heart rate rises. Also, it is usually lower in people who are physically fit.

Q: What's the material of the butterfly valve seat?: Tianjin saide valve limited company can provide all kinds of valve seat material for the majority of users: white food gum X1 - X2 - X3 - Hypa EPDM rubber X4 rubber X5 - resistant rubber X6 - fluorine rubber X7 - heat resistant ethylene propylene rubber X9 silicone rubber and PTFE F4.

Q: How does the pneumatic butterfly valve control the angle of opening?: This is really not good, control seems to be pneumatic defects, can only rely on the feeling

Q: How to use the fire butterfly valve properly?: Clamp and groove type and signal butterfly valve, the first two have what requirements of installation, the operating handle can rotate to open and close the valve installation, signal wiring, mouth down, to prevent water and caused a short circuit three line grounding and alarm line for leakage protection and monitoring of the valve open or closed, general are in line with the alarm valve or flow indicator matched with water, indicating the spacing of not less than 300mm, no other special requirements

Q: What are the functions and uses of butterfly valves?: Industrial butterfly valve features, capable of high temperature, applicable pressure range is higher, the valve nominal diameter is large, the valve made of carbon steel, the valve plate sealing ring using metal rings instead of rubber rings. Large high temperature butterfly valve welded by steel plate, mainly used for high temperature smoke duct and gas pipe.Construction: mainly composed of valve body, valve stem, disc and sealing ring. The valve body is cylindrical and has short axial length and is internally provided with a plate.

Q: How does PLC control butterfly valves?: PLC control butterfly valve, usually control pneumatic butterfly valve or electric butterfly valve.PLC control pneumatic butterfly valve, that is, PLC program control, electric control, gas control, gas control butterfly valve;PLC control electric butterfly valve, that is, PLC program control electric, electric control butterfly valve.Control requirement:All PLC output contacts must be isolated from the intermediate relay and indirectly controlled by an intermediate relay.

Q: e.g. a patient with a prosthetic aortic valve and a patient with a prosthetic mitral valve. Also, can you get stenosis of mechanical valves or just tissue grafts?Thanks!: mechanical okorder /

Q: Hey YA! I am looking at getting an 01 Honda Prelude this month and valve adjustment keeps coming up when people discuss this car and other cars as well. What is this? Does it cost a lot to do, and is it important? Thank you!: Not at all a big expense most places should do it for $90 -150 including the gasket . Takes me about an hour to do one. If you don't adjust them eventually you could wear the cam possibly although I've never seen any issues from not doing it. If they are too tight then possibly they could've got the engine hot . If they are too loose which is what they should do as they wear they'll just be a little noisy until you get them adjusted if I can help in any other way please let me know hope this helps

Q: Buried extension butterfly valve is buried or need to repair the valve well, can build the valve well, the extension rod butterfly valve installed in the valve well, the extension rod to avoid covers, the top of the valve well out, so that the hand wheel in the ground operation.Atlas S143 is less than the inner diameter of DN150 valve wells only 1200mm, DN200-DN250D diameter of only 1400mm, 700mm valve covers, valve rod and a handwheel to lengthen through the valve cover, valve wells is built to cover the embedded pipe or tube? Is there a standard atlas?: It's better to get a valve well for future maintenance.
