Specifically, the device further comprises a shell 1, the base 3 is arranged on the shell 1, and the shell 1 is connected with an air inlet joint 13 communicated with the pressure fluid inlet and an air outlet joint 5 communicated with the pressure fluid outlet.
Specifically, the base 3 is provided with a sealing seat, the diaphragm assembly 12 includes a diaphragm 121 capable of contacting with a sealing surface of the sealing seat, and a part of the flow passage is disposed between the sealing seat and the diaphragm 121.
Specifically, the base 3 is further connected with a flange 6, the guide sleeve 10 is mounted on the flange 6, and the flange 6 compresses the peripheral end of the diaphragm 121 on the sealing seat. The base 3 is provided with a heater 2 and a temperature sensor 4 arranged beside the heater 2. The diaphragm 121 may isolate the armature 7 from liquid water and vapor in the pipe, the heater 2 is mounted on the base 3 for low temperature deicing, and the temperature sensor 4 is mounted on the base 3 at a point close to the heater 2 for monitoring temperature.
