[0025] In order to realize the purpose of one-way conduction, a plug ball 41 is arranged in the guide groove 21, when the water flows from the water inlet pipe 5 to the through hole 2, it can flow smoothly, and when it flows in the opposite direction, it will push the plug ball 41 to the right side, and finally make it abut against the connection between the guide groove 21 and the water channel 3, at this time, the plug ball 41 will block the water channel 3, thereby realizing the purpose of one-way conduction.

[0026] In order to achieve the purpose of controlling the pressure and bidirectional blocking by using the plug ball 41, the side edge of the plug ball 41 close to the water channel 3 is transversely connected with a connecting rod 4 penetrating to the outside of the pipe body 1, the side edge of the pipe body 1 is provided with a rod hole 31 communicating with the water channel 3, the connecting rod 4 penetrates to the water channel 3 through the rod hole 31, and a second screw thread 43 is arranged on the outer ring of the connecting rod 4 away from the plug ball 41, so that the outer ring of the connecting rod 4 outside the pipe body 1 is screwed with a screw block 44, and in use, the position of the screw block 44 can be changed by screwing, so that the control of the left movement stroke of the plug ball 41 is changed, the gap between the plug ball 41 and the guide groove 21 is different when the plug ball 41 moves to different positions, and thus the control of the pressure can be realized, and when the screw block 44 is screwed to the leftmost side, the movement of the plug ball 41 can be completely limited, so that the plug ball 41 is tightly pressed against the rightmost side of the guide groove 21 to block the water channel 3, and the purpose of bidirectional blocking is achieved, and the existence of the connecting rod 4 and the screw block 44 can also avoid that the plug ball 41 is washed away by the water flow to the left.

[0027] The end of the connecting rod 4 is fixed with a limiting block 42, and the diameter of the limiting block 42 is larger than that of the connecting rod 4, so that the screw block 44 cannot be screwed off from the outer ring of the connecting rod 4 and lost.
