This valve is to stop the pump when the intake, through the intake of water to cut off the backflow, to prevent water from being returned to empty, the air can not enter the valve above the part of the water pipe, rest assured
Q:How can the fast closing noise check valve prevent water hammer?
Biaoguan valve that once the pump stopped, check valve spool in the spring or other auxiliary device for double end under the action of force balance in advance to the closed position, can greatly reduce the amount of water and initial water reflux falling height, water hammer force is calculated by gravity superposition, to reduce the amount of water is equal to the reduced gravity, but fell short height reduces the inertia time is relatively reduced speed, and can prevent the formation of destructive or reduce water hammer water hammer.
Q:The check valve on the air pipe is installed in front of the fan and is there any difference in the back (direction is correct)?
Installed in front of the wind blowing, the top open check valveIt is difficult to install the check valve, which is installed on the rear by the force of air suction.

Q:How many kinds of structure are there in the check valve?
3 butterfly check valve structure similar to butterfly valve, its structure is simple, flow resistance is small, water hammer pressure is smaller;4, diaphragm type check valve has a variety of forms, are used as the opening and closing the diaphragm, due to its good waterproof performance, simple structure, low cost, rapid development in recent years, but the use of diaphragm valve temperature and pressure by the diaphragm material limited;
Yue,located in Ducun Industrial Park, Linhu Town, Wuzhong District, Suzhou, mainly produces valves. Our company is equipped with one scale automatic static coating line, two assembly testing lines, many sets of semi-automatic assembly testing equipment as well as processing equipment such as 5m,3m and 2m vertical lathes, 4m and 2m milling machines and boring machines.
