Abstract

The invention discloses a pipe fitting which comprises a pipe fitting body. Three interfaces are arranged on the pipe fitting body, inner threads are arranged inside the interfaces, the outer walls of the interfaces are provided with grooves, outer threads are arranged inside the grooves, fastening nuts matched with the outer threads are arranged in the grooves, at least three notches are formed in each interface, and the length of each notch is smaller than the 1 / 2 length of each interface. The contact area is decreased by arranging the notches on the pipe fitting interfaces, so that the assembly is simple and convenient, and the pipe embedding length can be clearly known. The twice fastening can be performed on the pipe fitting and a pipe through the fastening nuts in the notches, and the pipe fitting is convenient to use.

Description

technical field [0001] The invention relates to the field of pipeline conveying equipment, in particular to a pipe fitting. Background technique [0002] Pipe fittings are a general term for components that play the roles of connection, control, direction change, diversion, sealing, support, etc. in the pipeline system. They are an important part of connecting pipes to pipelines. , flange fittings and welded fittings four categories. Mostly made of the same material as the pipe. There are elbows, flanges, tees, crosses, and reducers. Elbows are used where pipes turn; flanges are used to connect pipes and pipes to each other, and are connected to pipe ends; tee pipes are used where three pipes gather; four-way pipes are used where four pipes gather; Diameter pipes are used where two pipes of different diameters are connected. The existing pipe fittings are cumbersome to assemble and the embedded length of the pipe cannot be known during the assembly process, which is inco...
