Electric throttling control box

摘要: The utility model relates to an electric throttling control box, which comprises explosion-proof case and motor, wherein the motor is arranged in case, provided with a fuel tank, hydraulic pump digital display instrument, provides power source for pump, inlet end of communicated outlet manifold block six pressure interfaces via uniflow valve, respectively connected accumulator, transducer, overflow decompression speed regulating valve gauge, signal terminal transducer three-position four-way reversing tank. box compact structure, good performance, long service life, reliable performance high precision, changes mode sensing mode, can adapt hostile natural environments. Besides, simultaneously switches two liquid-operated throttle valves meanwhile monitoring related drilling well parameters, example standpipe casing pipe pressure.
