Anti-impact pipe joint structure

Abstract

The invention discloses an anti-impact pipe joint structure. The anti-impact pipe joint structure comprises a bearing port and an inserting port in insertion matching of pipe fittings; a sealing ring is arranged between the bearing port and the inserting port; plane annular shoulder tables perpendicular to the axis of the pipe fittings are formed in the transition places of the inner wall of the bearing port and the inner walls of the pipe fittings; anti-impact pads are arranged on the shoulder tables; and multiple positioning cones with tip-shaped ends are fixed on the end surface of the inserting port in the axis directions of the pipe fittings. The anti-impact pipe joint structure prevents damage caused by direct collision between the end part of the inserting port and the bottom of the bearing port, achieves the effect of protecting the inner walls of the pipe fittings and corrosion resisting layers, and guarantees normal service life of a pipe; meanwhile, in the inserting process, the positioning cones are inserted in the anti-impact pads for positioning, so that the inserting connection stability can be improved, and the outward elastic force effect on the inserting port by the anti-impact pads in deep insertion of the inserting port can be eliminated; and in addition, the structure simplifies the inserting construction requirements, can accelerate the pipe fitting connecting speed to a certain extent, and achieves the purposes of accelerating the construction progress, shortening the construction period and saving the construction cost.

Description

technical field

[0001] The invention relates to the field of pipe joints, in particular to an anti-impact pipe joint structure. Background technique

[0002] When the socket-type pipe fitting is connected into a pipeline, the socket of the pipe to be connected is inserted into the socket of the pipe to be connected, and the sealing ring between the socket and the socket is used to achieve the purpose of sealing and preventing slipping between the pipes to be connected. During the splicing process, the depth of the socket inserted into the socket is not easy to grasp, and it is easy to cause the end of the socket to collide with the bottom of the socket, resulting in wear at the end of the socket and the bottom of the socket, or even damage to the anti-corrosion layer, shortening the service life of the pipeline. In order to avoid the occurrence of the above phenomenon, the plugging process needs to be carried out carefully, which will easily affect the construction progress,...
