Quick and automatic sealing pipeline joint

Abstract

The invention relates to a quick and automatic sealing pipeline joint, and belongs to the technical field of pipeline connection sealing. The quick and automatic sealing pipeline joint is composed ofa joint body, a fixing ring, a sealing ring, a pressing ring, a bolt, an anti-disengaging chain and a self-locking hook. One or two ends of the connector body are matched with a pipeline outer ring through the sealing ring. During mounting, only a pipeline needs to be inserted into a sealing ring hole, mounting and dismounting are convenient and rapid, the sealing effect is good, and the sealing effect is better as water pressure in the pipeline increases. The pipeline direction can be adjusted in a universal manner. The quick and automatic sealing pipeline joint can adapt to the connection ofpipelines of various diameters, is particularly suitable for rush drainage and rush filling on the disaster-resistant fields and rescue fire-fighting sites, can save a large amount of valuable time for rescue sites, and has remarkable social benefits and economic benefits. The problems that an existing pipeline is connected through a flange and is limited by a construction site, the mounting anddisassembly are extremely inconvenient, connecting bolt holes are not easy to align, the sealing performance is poor because the pressing force of each bolt is inconsistent, and leakage occurs easilyare solved.

Description

technical field [0001] The invention relates to a quick and automatic sealing pipeline joint, which belongs to the technical field of pipeline connection sealing. Background technique [0002] With the development of society and the needs of engineering construction, pipelines are used more and more frequently, such as urban water supply and drainage pipelines, water inlet and outlet pipelines of hydropower stations and irrigation and drainage stations, and underground cable protection pipelines; existing pipelines are mainly divided into metal Pipelines and non-metallic pipelines, non-metallic pipelines are connected by welding, while metal pipelines are mainly welded or threaded; for most projects, welding cannot be used due to the limitations of the construction site and environment The method is to use the flange connection method; the flange connection method is to make flanges at both ends of the pipeline, pass through the flanges at both ends and put sealing washers i...

Problems solved by technology

[0002] With the development of society and the needs of engineering construction, pipelines are used more and more frequently, such as urban water supply and drainage pipelines, water inlet and outlet pipelines of hydropower stations and irrigation and drainage stations, and underground cable protection pipelines; existing pipelines are mainly divided into metal Pipelines and non-metallic pipelines, non-metallic pipelines are connected by welding, while metal pipelines are mainly welded or threaded; for most projects, welding cannot be used due to the limitations of the construction site and environment The method is to use the flange connection method; the flange connection method is to make flanges at both ends of the pipeline, pass through the flanges at both ends and put sealing washers in between and fasten them with bolts; for Some projects, such as the connection of pipelines in ditches, underwater pipelines and pipelines in pump rooms, are extremely inconvenient to install and disassemble with flange connections due to the limitations of the construction site. On-site, etc., the pipeline needs to be quickly connected, and the use of flange connection will lead to a very slow connection speed, which seriously affects the rescue speed

In addition, the use of flanges for pipeline connection will also cause the problems that the connecting bolt holes are not easy to align, and the pressing force of each bolt is inconsistent, resulting in poor sealing and easy leakage.
