When water pressure needs to be adjusted, the adjusting handle 526 is rotated to enable the adjusting handle 526 to compress the spring 525, the spring 525 is shortened, meanwhile, the spring 525 drives the adjusting plate 523 and the needle valve 524 to move rightwards, the needle valve 524 adjusts the flow of water at the inlet 522, when the flow of water at the inlet 522 is increased, the water pressure extrudes the adjusting plate 523 to move leftwards, meanwhile, the needle valve 524 is pulled to move leftwards, the inlet 522 is narrowed, the flow of water at the inlet 522 is reduced, and the flow of water at the outlet 521 is kept stable, so that the water in the water pump connector body 2 can keep constant pressure in the flowing process, and damage to the water pump connector body 2 due to unstable water pressure is avoided.
After the use, the valve 513 is rotated in the opposite direction, the valve 513 drives the valve body 511 to move downwards, the water source is closed, the water pipe is detached, the blocking cover 4 is aligned with the fire-fighting connector 21, the clamping jaws 41 extend into the fire-fighting connector 21, and the clamping jaws 41 are rotated to clamp the clamping jaws 41 in the clamping grooves.
The foregoing description shows and describes several preferred embodiments of the invention, but as aforementioned, it is to be understood that the invention is not limited to the forms disclosed herein, but is not to be construed as excluding other embodiments and is capable of use in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
