At this time, the second compression spring 85 is squeezed, and the lower end of the rocker 86 swings inward to make the connecting protrusion 88 move inward, and then put the connecting mechanism 8 into the corresponding slot 211, and then rotate the screw 83 in the reverse direction to make the movable rod 82 move downward. Under the elastic force of the second compression spring 85, the slide bar 84 moves inward, and when the movable rod 82 moves downward, the rocker The inner end of the rod 87 swings downward, so that the rocker 87 drives the lower end of the rocker rod 86 to move outward, so that the connecting protrusion 88 is inserted into the corresponding groove 211, and the connection between the first valve body 1 and the second valve body 2 is realized. Similarly, when disassembling, the above process is reversed. First, operate the closing mechanism 5 so that the closing plate 55 closes the water inlet pipe 3, and then rotate the screw 82 forward to disengage the connecting protrusion 88 from the corresponding groove 211, and then pull the first valve body 1 upward. The present application can realize the rapid installation and disassembly of the first valve body 1 and the second valve body 2, which greatly reduces the steps during maintenance, thereby improving maintenance efficiency.
