How to select the check valve of American standard power station

We know that the working environment of the American standard power station check valve needs to be as far away as possible from the source of medium pulsation, with small vibration and pressure fluctuation, which is more convenient when the pipeline is clean.

    Generally, the selection of the American standard check valve series products mainly considers the state of the fluid in the pipeline system, the nature and the pressure and temperature requirements. The selection of the American standard power station check valve also needs to be based on the valve's connection size, internal structure, friction coefficient, valve Fixed technical properties such as wear resistance, strength, working temperature and aging performance of the flap. Only reasonable selection and scientific collocation can obtain the ideal use effect of the American standard power station check valve.

    According to the pipe interface size, the use type of the American standard power station check valve is determined:

    Horizontal installation pipelines with small nominal diameters are suitable for lift-type American standard check valves. This American standard check valve can be installed at any position in the pipeline, and the placement form is more flexible.

    For snapping machines or pipelines with high flow rates, we recommend using swing-type American standard power station check valves. This kind of American standard power station check valve has a fast opening and closing speed and a very small closing hysteresis angle, which effectively reduces the impact and return loss during closing. The pressure is not hindered when the medium flows, and the flow resistance is small.
