PURPOSE: An anti-freezing plate for a pneumatic valve is provided to prevent pneumatic valves from being frozen by installing anti-freezing plates to be directly connected to the valves without additional device between the valves. CONSTITUTION: An anti-freezing plate for a pneumatic valve comprises an electric heating cover(110), a heating plate(120), a wire(130), and a temperature controller(140). Coupling holes(111) are formed in the edges of the electric heating cover to detachably attach the electric heating cover to a pneumatic valve. The heating plate is formed inside the electric heating cover and comprises a heating device for heating. A power plug is formed in the end of the wire to supply electricity to the heating plate. The temperature controller is formed in the middle of the wire to control the temperature of the heating plate. |
