Introduction to the Principle of Gas One-way Valve

      Gas one-way valve is a kind of gas path diaphragm one-way valve. Its principle is composed of valve body, valve cover and diaphragm. One end of the valve body is a joint with a central through hole, and the other end is connected with the valve body by a threaded hole. Place one or more diaphragms in the body cavity. A central through hole is arranged on the valve cover, one end is a joint, the other end is extended into the valve body cavity and one or more ventilation grooves are arranged at its end. The diaphragm achieves one-way effect under the action of airflow pressure.
