Valve mounting structure

The utility model belongs to the field of valves, and particularly relates to a valve installation structure, which solves the problems of time-consuming installation and poor sealing performance in the prior art, and comprises a valve body and a flange, one side of the flange is fixedly connected with two convex blocks which are symmetrically arranged through screws, one side of the valve body is provided with two grooves which are symmetrically arranged, and the two convex blocks are fixedly connected with the flange through screws. The two protruding blocks are located in the two grooves correspondingly, two symmetrically-arranged pressing blocks are assembled in the valve body in a sliding mode, the bottoms of the pressing blocks are fixedly connected with connecting rods through screws, and ejector rods are welded to one sides of the connecting rods. When the flange is installed, the protruding block slides into the groove, then the protruding block pushes the pressing block, the limiting rod loses the l
