[0026] Working principle: Drain pipes can be divided into reinforced concrete pipes, concrete pipes and plastic drain pipes according to their materials. In daily life, the most common ones are plastic drain pipes, which are mainly used to discharge sewage, rainwater and farmland irrigation and drainage. During the use of the existing drainage pipe connecting valve, if impurities in the pipe are blocked on the inside of the valve, the valve cannot drain water, and the subsequent cleaning operation is cumbersome.

With the cooperation of the fixing plate 5, the sealing cover 4 and the input pipe 2 are re-fixed and connected. With the cooperation of the sealing ring 7, leakage of liquid in the pipeline can be prevented. When the valve needs to be closed, the handle 18 can be pulled to slide on the inner side of the limit platform 20, thereby driving the valve body 13 to rotate through the threaded rod 17, and moving the rubber pad 15 to the input and output ports on both sides. At this time, the threaded rod 17 will drive the valve body 13 to move downward while rotating with the cooperation of the threaded cylinder 19, thereby pressing the rubber pad 15 tightly against the input and output ports at both ends of the inner side of the drain valve body 1, preventing the liquid inside the valve from still flowing after the valve is closed, thereby solving the problem that the existing drainage pipe connecting valve cannot be drained after being blocked, and the subsequent cleaning operation is more cumbersome.
