[0001] The utility model relates to the technical field of fire detection, in particular to a fire hydrant system water testing device for fire detection. Background Art

[0002] In order to ensure the normal operation and water supply capacity of the fire hydrant system, and to ensure that a reliable fire water source is provided in time when a fire occurs to protect people's fire safety, operators are usually required to test the fire hydrants regularly. The fire hydrant system water testing device for fire detection usually requires a connecting component to connect the water testing device to the fire hydrant joint. Then, by opening the water testing device, you can check whether the main pipes, branch pipes, valves, etc. of the fire hydrant system are operating normally to ensure that water can be supplied normally when a fire occurs.

[0003] However, after the existing fire hydrant system water testing device for fire detection is connected to the fire hydrant joint, since the water in the fire pipe needs to work under pressure, the water pressure will push the axial seal at the connection, thereby changing the state of the seal, causing water leakage, thereby affecting the fire fighting effect; at the same time, since a large number of tests need to be carried out during the fire detection process, each connection between the water testing device and the fire hydrant joint requires flange and bolt cooperation, and the connection efficiency is low, thereby affecting the detection efficiency.
