The output of the actuator unit 30 is connected to a solenoid valve or a direct-current high-pressure pump (not shown). When the control unit 10 inputs a low level signal to an execution unit 30, the execution unit 30 turns on and drives a first solenoid valve (not shown) to turn on. When the first solenoid valve (not shown) is opened, the external air compressor inputs high-pressure air into the tube, and at this time, the detecting unit 20 detects the pressure value in the tube (i.e., detects whether there is leakage in the tube or the water valve is not dense), for example: the normal pressure value is 5 mpa. When the pressure value in the pipe is greater than the normal pressure value, the detecting unit 20 inputs a pressure signal into the control unit 10, the control unit 10 outputs a high level signal to an executing unit 30, the executing unit 30 is switched from an on state to an off state, at this time, a first solenoid valve (not shown) controlled by the executing unit 30 is closed, the external high pressure gas stops inputting the pipe, and simultaneously, the pipe is depressurized, and when the pressure value of the pipe is reduced to the normal state, the control unit 10 inputs a low level signal to the other executing unit 30, so that the other executing unit 30 is turned on.

At this time, the detecting unit 20 detects a pressure value (i.e., water pressure) in the pipe, for example: the normal pressure value is 5 mpa. When the in-pipe pressure is greater than the normal pressure value, the detection unit 20 inputs a pressure signal to the control unit 10, and the control unit 10 inputs a high level signal to the other execution unit 30, and the other execution unit 30 is switched from an on state to an off state, and the second solenoid valve (not shown) is turned off. At this time, the dc high-pressure pump controlled by the other execution unit 30 is turned off, and the operation is stopped.
