The pressure relief valve 71 can be used when the pressure reduction and drainage are to be performed after the test is completed The pressure relief is performed so that after the decompression is completed, the quick male connector 220 and the quick female connector 230 can be removed from the quick female connector seat 67 and the quick male connector seat 66, respectively.

6. The present invention utilizes the design of the pressure relief unit 70 in conjunction with the second switching valve 52 and the first and second on-off valves 61, 62. Before the hose pressure test, the pressure relief valve 71 can be used to make up water .

To sum up, the electric hose quick-connector hydraulic pressure tester of the present invention can not only effectively shorten the man-hours required for the hose hose pressure test of each fire hose, but also double the number that can be detected during working hours The number of such fire hoses can avoid the occupational injury caused by frequent manual water pumping by the detection personnel, so it can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. Any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still classified as This invention covers the patent.
