Description

A quick-disassembled pipeline connection device

technical field

The utility model relates to a pipeline conveying system, in particular to a pipeline connection device which can be quickly disassembled and assembled.

Background technique

In large-scale compressed air or fluid pipeline systems, it is usually necessary to use large-diameter delivery pipelines in conjunction with small-diameter delivery pipelines. For small pipelines, small pipe joints can be used, but this type of pipe joint is not suitable for large pipes. Pipelines with smaller diameters cannot meet the requirements of large pipelines because of their connection strength.

For the connection devices of larger diameter pipelines, the flange connection is generally used at present, which needs to be welded on site and then leak tested. If the weld has welding defects such as slag inclusion, it needs to be reworked, which has higher requirements for the on-site installation workers. The installation efficiency is low and it is not easy to disassemble; for other large-diameter connection devices currently on the market, such as the large-diameter pipe connection device provided by the Chinese invention patent (application number: 2010105779998), there is also the problem that the aging sealing element cannot be replaced, due to the sealing Components such as rings are consumable materials, which will cause aging and other phenomena after a period of use, which will affect the transportation of the medium in the pipe. When repairs are required for these reasons, it is necessary to disassemble from the head of the pipe until the damaged joint is removed. Disadvantages such as heavy workload, long maintenance time, time-consuming and labor-intensive, high cost.

Preferably, the width of the positioning ring (7) in the present application is 1.5 times the wire diameter of the sealing ring (3).

The sealing device described in this application includes a ring frame body (4) and a pressure ring (5). The pressure ring (5) is sleeved on both ends of the ring frame body (4). An annular boss (41), the said annular boss (41) is provided with a positioning ring (7), and the two end surfaces of the positioning ring (7) respectively offset the pipes (6) on both sides. In this application, an annular boss is provided on the inner side of the annular frame body to facilitate the replacement of aging parts in the actual operation process and improve the work efficiency of workers. The annular boss and the positioning ring will limit the annular frame body (4) to only one side of the pipeline Direction Moves in one direction. When the sealing ring needs to be replaced, first open the first semi-annular body and the second semi-annular body, loosen the pressure ring (5) and the annular frame (4), and move the annular frame (4) to keep about 1.5 from the end faces of the two pipes. After taking out the positioning ring (7) within a distance of twice the diameter of the sealing ring, the ring frame (4) and pressure ring (5) can move in both directions in the axial direction on the pipe. After the ring (3) is removed and replaced from the distance between the end faces of the two pipes at a distance of about 1.5 times the diameter of the sealing ring, put it back into the positioning ring (7), and the installation is completed quickly, without disassembling the pipe (6) and fittings on the pipeline. Complete seal element replacement.

Beneficial effects: the pipeline connection device provided by the application uses the positioning ring (7) through the design of the clamping groove (61) on the pipeline (6) and the clamping convex groove (11) on the outer shell, so that the application The connection device provided can quickly and conveniently replace the aging parts, which greatly saves the cost and improves the work efficiency.
