Problems solved by technology
LDPE and LLDPE resins have low melt viscosity, good fluidity and easy processing, so the selection range of their melt index is also wide, usually MI is between 0.3-3g / 10min. During the use of gas pipes, weather changes or Cracks appear due to other external reasons, but they cannot be found from the outside. If the cracks cannot be detected in time, the cracks will continue to deteriorate and cause gas leakage. Therefore, in view of the above problems, improvements are made in this paper.

The invention belongs to a gas pipeline detection system, which includes a PE gas pipeline and a box body. The box body and the PE gas pipeline are provided with a detection structure. The detection structure mainly includes: a round pipe, a sealing part, and a docking part , a reel, a hose, a probe, a detection part, and a discharge part, the round pipe is arranged on the PE gas pipeline, the sealing part is arranged in the round pipe and the PE gas pipeline, and the butt joint It is arranged on the round pipe, the wire reel is rotatably connected to the opposite side surfaces of the box body, the probe is arranged at one end of the hose, and the discharge part is arranged on the housing, the wire reel And in the hose, the present invention can detect the cracks of the pipeline, and can carry out internal detection without stopping the valve, and carry out internal observation through the micro camera. After the detection is completed, if cracks appear, the valve can be closed, and the residual gas inside Pull out, then replace that end of the tubing.
Description
technical field [0001] The invention belongs to the technical field of gas pipeline detection, and in particular relates to a gas pipeline detection system. Background technique [0002] PE pipe At present, in China's municipal pipe market, plastic pipes are developing steadily. PE pipes, PP-R pipes, and UPVC pipes all occupy a place. Among them, the strong development momentum of PE pipes is the most eye-catching. PE pipes are used in a wide range of fields. Among them, water supply pipes and gas pipes are the two largest application markets. PE resin is formed by the polymerization of monomer ethylene. Due to different polymerization reaction conditions such as pressure and temperature during polymerization, resins with different densities can be obtained, so there are high-density polyethylene, medium-density polyethylene and low-density polyethylene. Vinyl. When processing different types of PE pipes, according to the different application conditions, the correspondin...
