Air door temperature control device and method suitable for air inlet and air outlet of comprehensive pipe gallery

The invention relates to the technical field of comprehensive pipe galleries, in particular to an air door temperature control device and method suitable for an air inlet and an air outlet of a comprehensive pipe gallery. The device comprises a temperature sensing switch, a transmission mechanism and a valve, the temperature sensing switch comprises a shell and a piston, the piston and the shell jointly form a closed cavity and are filled with temperature sensing materials, the valve is installed at the air inlet and the air outlet, and the transmission mechanism is located between the piston and the valve, so that the piston is pushed and pulled to drive the valve to be opened and closed. According to the temperature control device, by means of the thermal expansion and cold contraction characteristics of the temperature sensing material, opening and closing of the valve are controlled by the environment temperature, and the temperature can be kept stable; cable power supply and manual control are not needed
