Splicing type pipeline welding position sealing detection device

Abstract

The invention relates to the technical field of pipeline treatment, and discloses a splicing type pipeline welding position sealing detection device which comprises a working box, the outer end face of the working box is movably connected with an auxiliary turning box, the auxiliary turning box comprises moving rollers rotationally installed on the wall face of an inner cavity, and a fixing block is fixedly installed on the top wall of the inner cavity of the working box. According to the splicing type pipeline welding position sealing detection device, when sliding butt welding is carried out on a pipeline, the pipeline is wrapped by a specific part in a sealing processing mechanism, an air bag in the mechanism is processed and then makes contact with the pipeline, then the surface of the air bag is moist and free of dust, and the air bag becomes tighter; and at the moment, pressurization is carried out through a cavity formed between the sealing processing mechanism and the pipeline, and detection is carried out through an air pressure detection mechanism.

Description

technical field [0001] The invention relates to the technical field of pipeline treatment, in particular to a splicing type pipeline weld seal detection device. Background technique [0002] A pipeline is a device connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump and boiler, the high pressure from the pipeline It can also be transported by the pressure or gravity of the fluid itself. At this stage, many pipelines are spliced ​​and welded before construction. It is often necessary to check the sealing of the welded joints of the welded pipelines to ensure safe use. Now In the first stage, after the pipelines are installed, the interior of the pipelines is filled with air or liquid, and the leakage cannot be found in time to repair it. In view of the above shortcomings, the present invention improves. Contents of the invention [0003] The object of the...
