[0056] Further, the process of disassembling the valve body 1 is:

[0057] First, twist the bolt piece 42, so that the bolt piece 42 drives the lower stop block 43 to rise, so that the stop block 43 will no longer limit the fixed ring 24, then the rotating ring 23 is twisted in reverse, so that the connecting pipe 21 releases the clamping part 22 from the tight state with the left water pipe 3, until the connecting pipe 21 returns to the original position, then the valve body 1 is separated from the right water pipe 3, so that the valve body 1 can be disassembled, the process is simple and fast.
