[0002] A fire hydrant is a fixed fire-fighting facility, and its main functions are to control combustibles, isolate combustion-supporting substances, and eliminate ignition sources. Since a fire hydrant is only used during a fire, most of the time the fire hydrant is in an idle state. In order to ensure that the fire hydrant can be used normally during a fire, it is necessary to conduct regular water pressure detection on the fire hydrant. The water pressure detection device of a fire hydrant usually consists of a conical main body, a pressure gauge, and a stop valve. By connecting the water pressure detection device to the fire hydrant, the water in the fire hydrant flows into the water pressure detection device, and then the water pressure value is detected through the pressure gauge.
