The check valve ( 一个- - - - - - 阀) : the check valve is also called or a one-way valve, its role is to prevent the backflow medium pipeline. The bottom valve of the pump suction off also belong to the check valve class. NRVG mute type check valve check valve ( 止回阀) : it is to take the initiative to prevent fluid backflow valve. Check Industrial Valves open valve under the effect of fluid pressure, fluid flow from inlet side to export side. When the import side pressure is lower than the export side henan personnel examination of website, the disc in the fluid under the action of pressure difference, their gravity factors such as active closed to prevent fluid backflow check valve ( 止回阀) As usual: divided into lift, swing, butterfly and several types such as diaphragm type. Lift check valve structure as usual and globe valves are similar, the disc along the channel in line for lifting activities, reliable action, but the fluid resistance is bigger, the occasion of light is suitable for small diameter. Lift check valve can be through type and vertical two kinds. Through lifting check valve can only be installed in a horizontal pipe, as usual and vertical lift check valve is installed in a vertical line as usual. Swing check valve disc around the axis of rotation. As usual the fluid resistance is less than the lift check valve, it is suitable for large caliber of occasions. Swing check valve according to the number of the disc can be divided into single swing, more than double disc swing and swing three segments. Single swing check valve is suitable for medium caliber as usual. Large diameter single swing check valve is used in the pipeline, to reduce water hammer pressure, had better use can reduce the water hammer pressure slowly-closing check Industrial Valves. Double disc swing check valve applicable Yu Dazhong diameter pipeline. Double disc swing check valve to the clamp structure is small, light weight, is a kind of check valve fast development; More disc swing check valve is suitable for large diameter pipeline. The structure of the butterfly check valve is similar to the butterfly valve. Its simple structure, small flow resistance, water hammer pressure is small. Diaphragm type check valve has a variety of structure situation, adopt the diaphragm as open-close part, hammer because its waterproof performance is good, simple structure, low cost, rapid development in recent years. But the use of diaphragm type check valve temperature and pressure is limited by the diaphragm material. DDCV double disc check valve check valve ( 止回阀) : standard swing check valve flue wafer check valves within the check valve check valve slow close check valve mute vertical check valve check valve check valve price micro resistance slowly-closing double disc type check valve H76 wafer swing check valve water hammer pressure is small, the disc shorter ones, and there is spring assisted closure, fast closing valves H44 flange type single swing check valve is large, the disc stroke length, need longer closing time H76 type of water hammer pressure is H44 1/2 ~ 1/5 ball type sewage check valve: the valve body adopts full channel structure, with large flow, the benefits of small resistance. Ball is applied to make the disc, suitable for high viscosity, suspension of industrial and living sewage pipe network valves: check valve ( 一个- - - - - - 阀) : also called or a one-way valve wuhan website construction, its role is to prevent the backflow medium pipeline. The bottom valve of the pump suction off also belong to the check valve class. Open-close part by medium flow and power to open or closed, to prevent the backflow medium valve check valve. Check valve as part of the active valve and important in the one-way flow of medium pipeline, only permits to medium flows in one direction, in order to prevent accidents.
