[0003] In order to realize static pressure detection and dynamic drainage detection, the prior art provides a detachable connecting pipe and installs a valve at the end of the connecting pipe to achieve sealing. For the detection of fire hydrants, the entire device is not always fixedly installed. After the detection, the entire device needs to be dismantled and carried to other places where fire hydrants are located, and the drain pipe port is opened and closed by the valve, which increases the volume and weight of the entire device. For technicians who repeatedly detect in multiple places, the burden is heavy. When only static pressure detection is required, after the connecting pipe is removed, the drain port of the detection device is in an open state and cannot be sealed, making it difficult to flexibly switch between static pressure and dynamic drainage detection.

The spring can push the plugging body 21 into the ball socket of the other partition 20. In this solution, by setting the partition 20 and the plugging body 21, the end face of the connecting body 10 is fixedly connected with a claw for connecting to a fire hydrant. After the connecting body 10 is connected to the fire hydrant, water will enter the chamber of the connecting body 10 and then the static pressure of the water can be observed through the pressure gauge 11. Force, and at this time, when there is no need to perform a drainage test, the water pressure and the thrust of the spring on the sealing body 21 make the sealing body 21 hit the partition 20 close to the port of the drain pipe 12, and the sealing body 21 sinks into the socket to seal the port of the drain pipe 12, and can seal the port of the drain pipe 12 by itself. Compared with the drain pipe 12 which is always in an open state, this solution can only perform static pressure detection, and can also selectively perform dynamic drainage test, which has a more flexible way of use, and no valve is required for sealing, the structure is simple, and it is easy to carry.
