An integrated pipeline sealing device for air leakage detection and filling

Abstract

The invention discloses a pipeline sealing device integrating air leakage detecting and filling.The device comprises a retaining ring structure wrapping the joint of two pipelines, the two ends of the retaining ring structure are provided with a fixing bolt and a fixing nut respectively, the retaining ring structure is composed of a plurality of arc-shaped connecting blocks which are sequentially connected, the face, facing the pipelines, of each arc-shaped connecting block is provided with a groove structure, the arc-shaped connecting blocks are provided with detection air bags which can be concaved in the groove structures, and a liquid injecting device is arranged outside the retaining ring structure.Compared with the prior art, the pipeline sealing device integrating air leakage detecting and filling has the advantages that the pipeline joint is sealed through the retaining ring structure, it is guaranteed that the whole seal detection device wraps the pipelines and no air leakage phenomenon occurs, on the premise, each arc-shaped connecting block acts on each axial portion of the circumferences of the pipelines, which portion of the circumference of the pipeline joint leaks air is checked through the detection air bags, and if an air leakage phenomenon is found, adhesive liquid can be injected into the device through the liquid injecting device to block a gap.

Description

technical field [0001] The invention relates to a sealing detection device, in particular to a pipeline sealing device integrating air leakage detection and filling. Background technique [0002] With the increasing development of the field of gas transmission, the use of pipelines has gradually been widely used, and the leakage of pipelines will cause human and financial losses; as we all know, pipelines are connected by pipes, pipe connectors and valves. Devices for gases, liquids or fluids with solid particles. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. In order to...

Problems solved by technology

Reliability and safety meet the safety requirements of fuel pipelines, and cleverly solve the problem of pipeline installation during construction. The design is novel, and it is a very good innovative solution with great market promotion prospects; this method simply uses sealing gaskets The pipe is sealed with the bolt structure, and the pipe is damaged after long-term use, and the problem of local air leakage cannot be fundamentally solved. It can only be continuously compensated for the approximate air leakage point, and more materials are lost , nor can it evaluate the sealing quality of the pipeline connection
