The utility model relates to liquid pipeline control technical field, concretely is a kind of three-piece butterfly valve for liquid pipeline control, including the valve body consisting of two inner valve body and two outer valve body, butterfly plate and hand lever are equipped between two inner valve bodies. Through quick-release assembly connection between valve body, the assembly includes axially arranged connecting rod, and the circumferential of valve body is provided with the clamping groove matched with connecting rod. One end of connecting rod is matched with nut through thread, and the other end is rotatably connected with fixed part through pivot, to realize quick disassembly and assembly. Safety assembly is also provided on inner valve body and outer valve body, including the sliding sheet that can slide in T-shaped arc sliding slot, and the sliding sheet contact surface is provided with polytetrafluoroethylene wear-resistant layer to form damping sliding, for circumferential limit connecting rod. The radial dimension of outer valve body is greater than inner valve body, and quick-release assembly is staggered distribution to form avoidance space. The utility model solves the problem that traditional butterfly valve disassembly is complicated and easy to leak, has the advantages of quick disassembly and assembly, stable connection, safety and reliability, and is suitable for efficient fluid control demand.
