Summary of the invention:
The automaton that the purpose of this utility model is to provide a kind of remote controlled plug valve to open or close, both solved the limited space of crowbar operation, reduce labor intensity of operating personnel, avoid operating personnel to enter the higher-pressure region operation again, reduce the generation of security incident.
The utility model is to realize above-mentioned purpose by following technical solution:
High pressure plug valve automaton comprises oscillating oil cylinder, strainer, oil pump, three-position four-way valve, the control valve piece, the signal feedback control device is formed, wherein the control valve piece comprises one way valve, choke valve, pressure regulator valve, the in-line of control valve piece is connected with choke valve and one way valve in turn, the in-line branch road has one way valve, between one way valve and in-line oil-in end pressure regulator valve is arranged, control valve piece oil return line is connected with one way valve and choke valve successively, the oil return line branch road has one way valve, one way valve and oil return line oil export extremity piece have pressure regulator valve, oscillating oil cylinder connects the control valve piece successively by pipeline, three-position four-way valve, oil pump, strainer, fuel tank, position sensor is contained in the oscillating oil cylinder top, the oscillating oil cylinder other end has plug valve, and the signal feedback control device is connected with position sensor by electric wire.
The beneficial effects of the utility model:
1, this device is by control system Long-distance Control high pressure plug valve, and operating personnel do not enter the higher-pressure region just can the control cock valve, guaranteed operating personnel's safety.Oscillating oil cylinder oil cylinder volume is less, not limited by the operating space, and it is big, easy to operate to open moment of torsion, has alleviated labor intensity of operating personnel.
2, control oil channel is equipped with pressure regulator valve, and oil circuit is equipped with each other presses, and has the position auto-lock function, and self-locking can be realized in the fully open/closed position of plug valve, has increased security of system.
3, this system is equipped with two external one way valves, possesses emergency function, when control oil channel breaks down, can use the On/Off of emergent oil circuit control cock valve.
