- Q: What is the difference between turbine butterfly valve and flanged butterfly valve?
- The worm gear is the driving mode and corresponds to the handle; the flange is connected and corresponds to the clamp. Flange worm valve is generally, the handle of the butterfly valve
- 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: Water supply pipe gate valve and butterfly valve which good?
- Butterfly valve is relatively applicable1 electric butterfly valve 0-90 degree rotation angle stroke valve, specific flow characteristics, small size, high performance price ratio2, electric valve up and down movement of the straight stroke control method, can be used as shut-off valve, large size, expensive3, electric butterfly valve can not be used for high temperature and high pressure conditions, not wear-resistant. Electric gate valve is generally used to close the material with a grain of material, suitable for high temperature and high pressure conditionsOur company specializes in the production of various types of valves, there is a need to help me, I would like to help
- Q: Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?
- Hard seal butterfly valve in any case, the reverse loading will cause tight seal.
- Q: What does butterfly valve do?
- [1] butterfly valve is also known as turn over plate valve, is a simple structure of the control valve, but also can be used for low pressure pipe medium switch control.[2] butterfly valve: butterfly valve refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. 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. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow. Butterfly valve categories are: handle butterfly valve, turbine butterfly valve, pneumatic butterfly valve, electric butterfly valve and so on.
- Q: Butterfly valve in use when should pay attention to what problems?
- In the process of using power pipe pneumatic butterfly valve, the need to pay attention to these problems, the first is to conduct a comprehensive inspection in the use of butterfly valve, check butterfly valve is in good condition, all parts are connected in place, the valve is loose and so on, wait to ensure that everything is normal, it can make an official use.
- Q: Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
- Louzhu asked extremely, since it is hard seal, it is bound to guarantee long-term work after zero leakage, or should be configured double eccentric soft sealing valve is more reasonable.
- Q: How to control the single acting pneumatic butterfly valve?
- Single acting pneumatic butterfly valve, Luoyang crown butterfly pneumatic butterfly valve, mainly divided into two types of normally open and normally closed. What kind of effect do you want to achieve?
- Q: Hi guys, i asked a question before pertaining to the amount of cylinders and asking if it meant V4 or V6 or whatever.I actually meant to say VALVES, not cylinders. IS there a direct correlation between VALVES and Clyinders..Eg, My car, which is a 2001 Neon LE states right on the engine block quot;16 VALVEquot; in bright letters. I am sure this is a 4 cylinder engine. I haven't had a car that broadcasted the number of VALVES before. Another car I had broadcast that is was a 3.3 Liter V6 right on the engine.Is there a mathematical relationship between VALVES and cylinders, or would my car be braodcasting 16 VALVES, because a 4 cylinder doesn't typically HAVE 16 valves, or what is the story??Recently, I was looking at an altima, and it said 24 valves. Can you tell just by the number of valves if it is a 4 cylinder or 6 cylinder or whatever??Thanks.
- Well a lot of valves signify that more air/gas is getting to the engine so it suggests a more powerful engine. So your car has 4 valves per cylinder. Now that's pretty much a standard number so most expensive cars don't really even talk about that. They mostly just advertise the displacement. You can't really tell the type of engine via the number of valves because it does vary by manufacturer. For example there could be a 16 valve V8 also also(2 valves per cylinder). There are some ratios that dont work like a 16 valve V6 because you cannot have 2.6 valves.
- Q: i just finished installing a sprinkler line for my lawn and i used anti siphon valves and 4quot; sprinkler heads. it says in the manual that it has to be at least 6quot; from the highest sprinkler. i think i made a mistake. i installed it 7quot; from the highest 'sprinkler line' . will i have a problem with that regarding the operation of the anti siphon valves and the sprinkler system itself?
- If the antisyphon valve is not leaking maybe you should focus attention on the main valve ( assuming it is a solenoid valve) to see if it closes completely. Another thing, if the irrigation zone is on an incline then the water in the system will drain to the lowest point. Sometimes it drains slowly causing the impression of a leaky feed valve.
