Forging and pressing integrated horizontal type male elbow with seat

Abstract

The invention discloses a forging and pressing integrated horizontal type male elbow with a seat and relates to the technical field of pipe fittings. The male elbow comprises a pipe fitting body, wherein one side of the outer wall of the pipe fitting body extends outwards to be provided with a branch pipe in a communicating mode, and the outer wall of one end of the branch pipe is provided with anexternal thread. According to the forging and pressing integrated horizontal type male elbow with the seat, a pipe fitting blank is formed through hot forging and pressing and then machined through anumerical control machine tool, various specifications are achieved, a fixing base is arranged on the side face of a non-machined body of the pipe fitting, and compared with a copper vertical type split male elbow with the seat, the body sealing performance is good, the inspection cost is reduced, and the strength of the pipe fitting is improved; the seat is arranged on the side face, so that thespace required for installation is reduced, and meanwhile, the problems that due to the fact that the external thread of the pipe fitting is too long, forging and pressing are not prone to forming, and the blank is prone to having defects are solved; and according to the forging and pressing integrated horizontal male elbow with the seat, through an injection air bag, an injection plate and injection pipes, the positions of the pipe fitting body and the pipeline can be sealed and waterproof, and the pipeline at the contact position is prevented from being rusted.

Description

technical field [0001] The invention relates to the technical field of pipe fittings, in particular to a forging integrated horizontal elbow with a seat and outer teeth. Background technique [0002] In the pipeline system, due to different use and installation environments, the demand for external thread extension products in different installation conditions is increasing. At the bottom of the thread, for on-site use, the welded connection is prone to defects such as water leakage at the weld and insufficient strength. In order to avoid these defects, multiple inspection procedures need to be added, which increases the manufacturing cost of the pipe fitting itself. At the same time, different The installation position also has different requirements for the position of the fixing seat. The fixing seat is arranged on the side of the thread, which is beneficial to save installation space. [0003] As the use environment becomes more and more complex, higher requirements are...

Problems solved by technology

[0004] The invention provides a horizontal forging and pressing integrated horizontal outer tooth elbow with a seat. The pipe fitting blank is formed by hot forging and then processed by a numerical control machine tool. Various specifications are realized, and the fixing seat is set on the side of the non-processing body of the pipe fitting. Compared with For the copper vertical split elbow with outer teeth, the body has good sealing performance, which reduces the inspection cost and improves the strength of the pipe fittings. The side seat reduces the space required for installation. At the same time, it solves the problem of excessive length of the pipe fittings Forging is not easy to form, and the blank is prone to defects. By injecting the air bag, injection plate and injection pipe, the position between the main body of the pipe fitting and the pipe can be sealed and waterproof, and the corrosion of the pipe at the contact position can be avoided.
