Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, in particular to a performance testing machine for fire hydrants and fire hoses. Background Art

[0002] Fire fighting equipment can be seen everywhere in the city, such as indoor and outdoor fire hydrants. Matched with the fire hydrant are quick connectors and water guns connected with flexible water pipes. The sealing performance and pressure resistance performance of fire hydrants and fire hoses are crucial for the safe use of fire hydrants. If there is a water leakage phenomenon, the water pressure entering the water gun during actual use will be affected to a certain extent. Therefore, the produced fire hydrants and fire hoses must undergo strict watertightness tests before they can be used. The existing watertightness tests for fire hydrants are all carried out manually, so there are many human factors, which easily lead to incomplete watertightness tests and affect the normal use of fire hydrants.

A number of test pipe orifices 405 are equidistantly provided on the main water supply pipe 404. In this embodiment, five test pipe orifices 405 are installed. The test pipe orifices 405 communicate with the main water supply pipe 404. The test pipe orifices 405 are inserted into the test chamber 5 and at the bottom of the test chamber 5. Quick connectors 10 are installed on all the test pipe orifices 405. One end of the main water supply pipe 404 is connected and communicated with the circulating water supply system 4. An external test port 6 is installed on one side above the test pipe orifice 405. One end of the external test port 6 is inside the test chamber 5, and the other end of the external test port 6 extends outside the test machine room 2.

[0019] The circulating water supply system 4 includes a water storage tank 401, a high-pressure water pump 402 and a voltage stabilizer 403. A first water inlet 401-2 and a first water outlet 401-1 are provided on the water storage tank 401. One end of the high-pressure water pump 402 is connected and communicated with the first water outlet 401-1 through a pipeline. The other end of the high-pressure water pump 402 is connected to a voltage stabilizer 403. The voltage stabilizer 403 is connected and communicated with the main water supply pipe 404 through a pipeline. The pressure range of the high-pressure water pump 402 is 0 - 12 MPa. The bottom inside the test chamber 5 is a water tank 501 with an inward concave arc structure. A water outlet hole 502 is provided at the low position of the water tank 501. The water outlet hole 502 is connected and communicated with the first water inlet 401-2 of the water storage tank 401 through a pipeline.
