The invention relates to the technical field of EDC backflow pipelines, in particular to an installation valve and an EDC backflow pipeline. One end of the fixing column is inserted into the fixing hole, and the surface of the end, away from the fixing hole, of the fixing column is in threaded connection with a nut; one end of the connecting block is fixedly connected with a connecting column, and the connecting column is arranged in the fixing column in a sliding mode; the device has the beneficial effects that a connecting block is pressed downwards, the connecting block drives a connecting column to move downwards, the bottom end of the connecting column extrudes four sets of clamping blocks elastically arranged on the side wall of a fixing column, so that the four sets of clamping blocks are all inserted into a clamping groove, and the ends of two sets of jacking blocks elastically arranged in the connecting column bounce into a first limiting groove; at the moment, the flange plate at the end of the back
