Abstract

The utility model provides a water plugging valve for a pipeline, which relates to the technical field of water plugging valves and comprises a valve body, the inner side of the valve body is connected with a water plugging gate plate in a sliding manner, the inner side of the valve body is provided with a water passing port, and one side of the valve body is fixedly connected with a water pipe connecting sleeve and a water pipe limiting sleeve. The outer surface of the water pipe connecting sleeve is connected with a water supply and drainage pipe. The water supply and drainage pipe is connected between the water pipe connecting sleeve and the water pipe limiting sleeve behind the valve body in a sleeved mode, the sealing ring is arranged between the water supply and drainage pipe and the valve body to improve sealing performance, the clamping plate is arranged on the front side of the valve body to form the U-shaped groove, and the water plugging gate plate is inserted into the U-shaped groove. The water supply and drainage pipe is quickly plugged by installing the water plugging gate plate in the U-shaped groove through up-down sliding, the expansion rubber ring for rainwater expansion is arranged on the water plugging gate plate, and when the water plugging gate plate is inserted into the bottom of the U-shaped groove of the valve body, the expansion rubber ring abuts against the edge position of the water passing opening, so that the sealing and water seepage preventing effects are improved.
