The technological scheme that its technical problem that solves the utility model adopts is: a kind of electromagnetism remote control of gas cut off valve is characterized in: which comprises at least explosion prevention electromagnet, power interface, armature, linkage rod, Monitoring and Controlling and data processing system; The power interface of explosion prevention electromagnet is connected with Monitoring and Controlling and data processing system by power line, and the side mouth place of explosion prevention electromagnet is equipped with armature, and an end of armature and linkage rod is flexibly connected, and the other end of linkage rod and the lever of cut-off valve bottom are flexibly connected.
The built-in control knob of described Monitoring and Controlling and data processing system and PLC control circuit board.
Described Monitoring and Controlling and data processing system are arranged in the control room away from cut-off valve.
Be bolted to connection bearing on the described explosion prevention electromagnet, bearing also is fixedly connected with the cut-off valve body.
The opening that described explosion prevention electromagnet is equipped with armature is fixedly connected with screwed retaining ring, armature is in the inboard iron core of explosion prevention electromagnet and the position between the screwed retaining ring, linkage rod is passed one side of screwed retaining ring and armature and is fixed, and the another side of armature is the inboard iron core of anti-electromagnet.
The bar hole on described lever bottom one side and linkage rod the right is flexibly connected, and lever bottom opposite side connects with the cut-out bar of pneumatic automatic cut off device.
Described lever top and carriage articulate, and the lever middle part is connected with positioning rod.
The beneficial effects of the utility model are owing to also be fixedly connected with the utility model electromagnetism telecontrol mechanism in the bottom of lever, when needing long-range cut-out combustion gas, Monitoring and Controlling and data processing system are that SCADA can attract armature by the telecontrol explosion prevention electromagnet, armature drives the linkage rod translation, the linkage rod pull lever turns clockwise around positioning rod, at this moment, carriage breaks away from from the lever top end, realizes the telecontrol of cut-off valve is cut off.
