This valve is mainly composed of body, disc, stem, seat and transmission equipment. Simple, compact structure, small, portable, convenient transportation, installation and removal. 90 degrees, opening and closing of the switch is rapid, operation is small, light energy, sealed performance is good, service life is long, can achieve zero leakage. Flow curve tending to straight line. Excellent regulation performance.
4. Sealing performance:
Rubber seal valve, close the disc and seat sealing performance is good, and the torque is small. Is small, the friction between the butterfly plate and valve seat seal. Disc of the valve shaft drive, butterfly plate do rotate 90 degrees. Butterfly plate, flexible for opening and closing, without jamming, jumping phenomenon, small torque. Large diameter valve can replace the sealing ring online, convenient maintenance. Reverse valve seal is not good
- Q:What's the difference between a butterfly valve and an eccentric butterfly valve? What is the difference in field applications?
- Avoid friction and wear on the sealing surface!And, at the time of closing, and opening the opposite, there is a better sealing effect! Now generally use eccentric butterfly valve as the main. That's all I know! If there is any mistake, please forgive me!
- Q:How do you draw the butterfly valve in the engineering drawing?
- Butterfly valve there are many kinds of painting, mainly designed to draw on the staff, according to the design institute out of the icon.
- Q:Seat has said to the previous owner that the car needs a new air mass meter and dump valve.I am putting a new air mass meter on it.Does it have a dump valve.I know very little on this subject.
- every turbo will have a dump valve(waste gate) to regulate the boost to the engine Dump valves are fitted to the engines of turbo charged cars and sit between the turbo outlet and the throttle body. When transitioning from a boosted state to a closed throttle state (as in between shifts), due to inertia, the turbo continues to pressurize air, but the closed throttle prevents the compressed air from entering the engine. In this case the pressure exceeds the preset spring pressure in the dump valve and the excess pressure is bled off to atmosphere. Even with a dump valve the compressed air acts as a brake on the turbo (slowing it down), because the pressure on the backside of the turbo is at a higher pressure than on the front side (and the air actually wants to flow through the turbo backwards). A blowoff valve is a more elegant solution to this problem by allowing the turbo to freewheel when the throttle is closed (equalizing the pressure on both sides of the turbo). Unlike a dump valve a blowoff valve can be used at multiple boost settings without reconfiguration. Blowoff valves are sometimes incorrectly called dump valves because they serve a similar function, but they are very different solutions to the same problem.
- Q:What's the difference between electric butterfly valve and electric two way valve?
- The valve can only be fully open or fully closed, so the controller only need a 1/4 angle stroke in control, so you only need to open and closed position control. The butterfly valve can be opened and closed at any position within 90 degrees, so a positioning device is needed on the electric head. If the valve is used (such as double eccentric butterfly valve or three eccentric), due to the eccentric effect, need to always have a butterfly valve opening and closing positions to control the torque of Disc Edition in the stem, especially in the valve closed to non preferred direction needs a torque to ensure the butterfly valve, which requires control device to provide a torque to make butterfly valve position or seal. Therefore, the ball valve only needs to drive device to meet the opening and closing, two positions can be, and butterfly valve but in the switch of the whole trip in the control.
- Q:can't locate freon intake valve for 03 jaguar an was wondering were it is located at
- If it has one it should be located on the smaller line near the AC compressor.
- Q:Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
- Front is the same, there is C refers to the body of the material is carbon steel, without C, usually refers to gray iron (cast iron is more common, so are generally omitted)
- Q:Butterfly valve, two-way pressure and one-way pressure what is the difference?
- The positive pressure and the reverse pressure, the pressure when the medium returns
- Q:What is the medium flow rate when the centerline butterfly valve is fully open?
- After inspection, the product certificate shall be attached to the factory.Butterfly: 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 air, water, steam, all kinds of corrosive media, mud, oil, metals and radioactive liquid media and other types of fluid flow.
- Q:Does the pneumatic butterfly valve need electricity?
- Are pneumatic, and directly rely on gas control, the most important thing is that the gas, then certainly have to take control of electricity!
- Q:How does the pneumatic butterfly valve control the angle of opening?
- The angle of the rotating shaft is controlled so that the angle of the butterfly valve is controlled. You just have a good electrical locator
