Valve with cleaning mechanism

摘要

PROBLEM TO BE SOLVED: To provide a valve having a cleaning mechanism capable of easily and surely cleaning the flow path of the valve. SOLUTION: A monitoring sensor 4 attached to an upper main body 91 detects and transmits a temperature, and a control unit 37 of a controller 35 takes in this temperature signal, recognizes a temperature drop, and projects a signal toward an electromagnet 10. Is output. The electromagnet 10 generates a magnetic force based on the protrusion signal, generates a repulsive force with the permanent magnet 15, moves the permanent magnet 15 and the cleaning bar 2 fixed to the permanent magnet 15 in the direction of the arrow 106, and moves the bar tip 25 into an orifice. Enter 51 and perform cleaning. When the generation of the magnetic force of the electromagnet 10 is stopped, the cleaning bar 2 moves in the direction of arrow 105 due to the restoring force of the spring 30 and is restored. The protruding operation is continuously repeated a plurality of times. [Selection diagram] Fig. 1
