Air control needle valve is powered by natural gas or independent gas supply, hydraulic oil as transmission medium, drive pipeline valve opening and closing of the mechanism, is to ensure the safe operation of oil and gas pipelines equipment.
The gas control needle valve directly takes the high pressure natural gas from the independent pipeline. After the gas is filtered, no pressure reduction is needed, and the gas reservoir is stored directly through a high pressure shuttle valve and a one-way valve. Using integrated modules, large flow and high voltage design technology, less control components to withstand high pressure, prolong the life of seals, reduce piping, reduce system leakage, thereby improving the overall safety of the equipment.
Mechanical drive mechanism: link with valve, receive hydraulic power, output switch valve required drive torque.
Gas-liquid conversion mechanism: when the actuator moves, the air source power is converted to hydraulic power.
Fluid control unit: by controlling the on-off of the gas-liquid circuit, a variety of valve switching modes are realized.
Electronic control unit: real-time monitoring of pipeline pressure parameters, emergency automatic cut-off, but also with human-computer interaction, data recording and other functions.
