The gas-liquid ball valve produced by Shanghai Europe valve is composed of pneumatic hydraulic actuator and high-pressure ball valve. The power source of the pneumatic hydraulic actuator is directly from the high-pressure natural gas of the independent pipeline. After being filtered, the natural gas is directly stored in the gas storage tank. The integrated module, large flow and high pressure design technology is adopted to make less control elements bear high pressure, prolong the service life of seals, reduce piping and system leakage points, so as to improve the overall safety of the equipment. The hydraulic system has the advantages of strong transmission rigidity, hard compression, stable transmission and easy sealing. Gas has the advantage of high compression ratio. The pneumatic hydraulic actuator combines the advantages of gas and liquid perfectly through the conversion of gas-liquid transmission mode. High pressure gas enters into the gas-liquid tank through the control system for conversion, and the constant pressure hydraulic oil in the tank is pressed into the corresponding hydraulic piston cylinder. At the same time, the hydraulic oil of the hydraulic piston cylinder flows back to another gas-liquid tank. The piston action drives the actuator to drive the valve to open or close smoothly. The performance of pneumatic hydraulic actuator is stable and reliable. The whole travel time of the actuator can be adjusted by adjusting the flow of hydraulic oil.
