What is Check Valve?
Check valve refers to a valve whose opening and closing parts are circular discs and rely on its own weight and medium pressure to generate actions to block the backflow of the medium. The check valve is an automatic valve. Do not energize or ventilate, which means that the facility is powered off and the check valve will still work normally. The check valve has a designated medium flow direction, the medium flows in from the inlet end and flows out from the outlet end. When the inlet pressure is greater than the sum of the weight of the disc and its flow resistance, the valve is opened. On the contrary, the valve is closed when the medium flows back, thereby preventing the medium from flowing back and protecting the pipeline, compressor and pump.
Check valve widely used in oil and gas, water treatment, mining, power plant, boiler, and so on.
