[0002] Fire pump couplings are fire-fighting facilities for high-rise buildings in accordance with the "Code for Fire Protection Design of Buildings". They are usually connected to the water supply system of fire-fighting equipment such as the automatic sprinkler system or fire hydrants in the building. In the event of a fire, the water pump of the fire truck can quickly connect to the fire-fighting equipment in the building through the interface of the coupling, and deliver water for pressurization, so that the indoor fire-fighting equipment can obtain sufficient pressure water source. Outdoor underground fire pump couplings are usually installed in fire wells. Since the frequency of use of water pump couplings is not high and they are located in a relatively humid environment, it is easy to cause aging and corrosion at the interface, resulting in difficulty in opening and closing.
