Pipeline gate valve convenient to disassemble and assemble

The utility model relates to the technical field of pipeline gate valves, and discloses a pipeline gate valve convenient to disassemble and assemble, which comprises a valve body, a valve column is fixedly mounted on the upper surface of the valve body, a valve rod is movably mounted on the surface of the inner wall of the valve column, and a valve plate is fixedly mounted at one end of the valve rod. According to the pipeline gate valve convenient to disassemble and assemble, the valve rod is rotated to drive the valve plate so as to control water flow in the valve body, the filter plate is rotated to drive the supporting frame to rotate in the sliding groove, the supporting frame rotates to drive the clamping block to enter the clamping groove to be clamped and fixed, and impurities in water can be filtered and blocked through the filter plate; after a clamping block enters a clamping groove, an elastic plate is driven to operate through operation of a first spring, so that pressure is applied to a baffle m
