Abstract

The utility model provides a socket joint formula pipeline interface anti-disengaging structure, including half the husband's ring half body, two half the husband's ring socket of being connected by the connecting piece, ring socket constitutes the cooperation that the damaged department was kept away from to the restriction axial with the pipeline, constitutes the cooperation that restricts two pipeline axial separation between two sets of ring socket on treating two pipelines that connect. According to the scheme, the two pipelines to be connected are locked through the ring sleeve joints, and then are locked through the separation preventing structures between the ring sleeve joints, so that the pipeline joints are prevented from loosening and leaking water.

Description

Anti-drop structure for spigot-and-socket pipeline joint

Technical Field

The utility model relates to a pipe connection, specifically say exactly the anti-disengaging structure that socket joint formula pipeline interface position was used.

Background

At present, pipe body socket joint type connection is common, namely a pipe head section of one pipe body is inserted into a bowl-shaped pipe mouth section of the other pipe body, the pipe diameter of the bowl-shaped pipe mouth section is slightly larger than the pipe diameter of the other pipe body, and gluing sealing or arrangement of a sealing ring is reasonably selected according to the material, the pipe diameter, the application and the performance requirements of the pipe bodies.

The socket type pipeline joint in the prior art is convenient to install and low in cost, however, the axial direction does not have a positioning and anti-slip device, so that the axial direction does not have anti-slip performance, and particularly, when the geology of a pipeline laying area is soft, the geology is easy to deform, and the change of the pressure in the pipeline is large, the pipeline joint part is easy to misplace and deform, so that the pipeline at the socket part slips and leaks.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a socket joint formula pipeline interface anti-disengaging structure prevents that pipe joint is not hard up to drop under the effect of high-pressure rivers.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a socket joint formula pipeline interface anti-disengaging structure, includes half the circle of ha fu ring, and two half the circle of ha fu ring are connected into the ring socket by the connecting piece, and the ring socket constitutes the cooperation of restriction axial and keeping away from damaged department with the pipeline, constitutes the cooperation of restriction two pipeline axial separation between the two sets of ring socket on two pipelines of treating the connecing.

According to the scheme, the two pipelines to be connected are locked through the ring sleeve joints, and then are locked through the separation preventing structures between the ring sleeve joints, so that the pipeline joints are prevented from loosening and leaking water.

Detailed Description

The utility model provides a socket joint formula pipeline interface anti-disengaging structure which characterized in that: the pipe joint comprises half bodies 10, wherein the two half bodies 10 are connected into ring sockets through connecting pieces, the ring sockets and the pipes form the fit for limiting the axial direction to be far away from the damaged part, and the two groups of ring sockets on the two pipes to be connected form the fit for limiting the axial separation of the two pipes.

According to the scheme, the two pipelines to be connected are locked through the ring sleeve joints, and then are locked through the separation preventing structure between the ring sleeve joints, so that the two pipelines are limited to be separated axially, and the pipeline joints are prevented from loosening and leaking water.

The inner ring of the ring socket joint at the bowl-shaped pipe orifice 1 of the socket pipe forms a horn-shaped structure which is attached to the outer wall of the bowl-shaped pipe orifice 1. Thus, the shape of the ring socket is matched with the bowl-shaped pipe orifice 1 to form a slope, so that the unidirectional displacement of the pipeline relative to the ring socket along the axial direction is prevented, and the matching for limiting the axial separation is formed

The inner arc surface of the half 10 half. Only the half 10 of the straight pipe mouth is provided with a tooth-shaped structure

1-3 locking lugs 11 are uniformly arranged on the outer arc surface of the half 10 half. This facilitates the connection of the two ring sockets.

Claims (3)
