Valve pipe fitting capable of preventing looseness

The utility model relates to the technical field of valves, which comprises a valve body and an outer cover, a nut is arranged at an opening in the upper portion of the valve body, a threaded rod is arranged on the lower surface of the outer cover, the periphery of the upper surface of the outer cover is in threaded connection with the opening in the upper portion of the valve body through a threaded nail, and a plurality of reinforcing assemblies are arranged on the periphery of the valve body. According to the anti-loosening valve pipe fitting, the valve and the outer cover are in threaded connection and then are reinforced through the threaded nail, then the positions of the valve and the threaded rod are fixed through the reinforcing assembly, the situation that the valve is loosened during installation is avoided, the stability of the valve pipe fitting can also be improved, and meanwhile, the valve is prevented from being loosened. And the reinforcing assembly can be conveniently disassembled through th
