The utility model is installed in the quick occluding device in the inflammable and explosive property gas transmission pipeline, comprise the sensor that is used for detecting the combustion explosion signal, be arranged on the electromagnetism block valve of inflammable and explosive property gas transmission pipeline and be used for the receiving sensor testing signal and send the controller of control signal to the electromagnetism block valve, described sensor is arranged at least in the pipeline at 30 meters of electromagnetism block valve.
Further, described electromagnetism block valve is unidirectional electromagnetism block valve, comprise valve body, valve seat, with the mangetic core assembly and the electromagnetic drive component of the corresponding setting of valve seat medium channel; Described mangetic core assembly comprises spool and valve rod, and described valve rod one end is connected with spool, the other end pass valve body and with can along valve rod in axial sliding mode be slidingly matched; Described electromagnetic drive component comprises that slidably laterally piercing into valve rod along valve rod is positioned at outside the valve body one section armature and is used to drive the electromagnetic coil that armature skids off from valve rod; Valve body is provided with spool is applied spring to valve seat direction pretightening force.
Further, described sensor is arranged in the unidirectional electromagnetism block valve upstream line, and described upstream line is positioned at spool one side.
Further, described sensing means be in flame sensor, pressure transducer and the electromechanical combustion explosion sensor a kind of, two or three.
The beneficial effects of the utility model: the utility model is installed in the quick occluding device in the inflammable and explosive property gas transmission pipeline, sensor can fast detecting arrive the combustion explosion signal, and signal passed to controller, controller can pass to electromagnetic coil with the control electric current rapidly, making it drive armature motion detaches from valve rod, spool can be closed gas port blocking-up air-flow rapidly under self gravitation and pressure spring thrust double action, time≤the 100ms that turn-offs from the sensor received signal to valve, can prevent combustion explosion effectively, avoid causing great combustion explosion accident along pipe transmmision.
