PE pipe hole plugging technology is a working method of pipeline construction of pipe network, running in the pipeline, mainly through the polyethylene pipe opening special equipment to complete. Its basic principle is: in the operation of the pressure conveying pipeline to a variety of construction or repair the pipe ends of double blocking, open hole sealing equipment of the pipe section truncated medium circulation use, in use to set up open temporary by-pass hole plugging equipment on both ends of pipeline connection is the construction work the pipe ends, let the pipeline medium conveyed by the temporary bypass stop, the whole pipeline still maintain normal transportation operation in the process of construction operation. According to the construction purpose and structure of different forms of the pipeline, in line with pressure operation of valve replacement, replacement pipe or pipe line, three splice and other fault block processing pipeline in the pipeline, will double blocking hole form. The opening is designed to block, two sets of the same specifications to open holes at both ends of the pipe installation in construction machine, electric welding and special polyethylene pipes in the pipeline connection in advance, opening the knife extends into the PE pipe pipe each out of a hole, the hole size by size the plugging head and. After the completion of the opening, the occluder is performed by the occluder. The plugging head falls into the opened hole, and the occluder is operated to make the folding leather cup or the sandwich butterfly valve plug open, and the plugging head is cut off back to back in the inner hole at both ends of the pipe section.
