Description

Technical Field

[0001] The utility model relates to the technical field of electric heat-melting sleeves, in particular to an electric heat-melting sleeve for a pipeline interface. Background Art

[0002] The electric hot melt sleeve is a kind of connecting pipe fitting that connects the jacket pipe together by electric hot melt through the PE sheet covered with mesh, bent and rolled. The existing electric hot melt sleeve has a relatively simple structure, which leads to the problem of easy damage during use. At the same time, the insulation effect of the external temperature is poor, which affects the use of the electric hot melt sleeve. Therefore, we propose a pipeline interface electric hot melt sleeve. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide an electric hot-melt sleeve for a pipe interface. A suitable foaming material is injected into the interior of the pipe body using an injection port. In combination with thermal insulation cotton and a protective sleeve, the influence of external temperature on the pipe can be effectively prevented. The electric connector is connected to the output end of an external welding machine, so that both sides of the pipe body are melted and fixedly bonded to the outside of the pipe, which can effectively solve the problems in the background technology.

Both left and right sides of the top surface of the tube body are fixed with fixing seats, and the top surface of the hot-melt electrode sheet is connected to the bottom end of the electrical connector, and the electrical connector is located inside the fixing seat. An identification column is installed on the inner side of the top surface of the hot-melt electrode sheet, and the identification column is slidably connected to the through groove on one side of the top surface of the tube body. The injection port is opened in the middle of the top surface of the tube body;

[0006] It also includes a limit baffle, wherein two limit baffles are respectively fixed on the left and right sides of the tube body, and a through hole is provided in the middle of the limit baffle.

[0007] The electrical connector is connected to the output end of an external welding machine, so that both sides of the tube body are melted and fixedly bonded to the outside of the pipe. When the tube body melts, the identification column extends out to facilitate personnel to judge the stability of the tube body fixation. The limit baffle can effectively limit the distance between the tube body and the pipeline interface. The set injection port can inject different types of foaming materials according to different usage conditions to ensure the sealing of the pipeline interface.

[0008] Furthermore, it also includes a placement groove and thermal insulation cotton. The placement groove is opened inside the pipe body. Thermal insulation cotton is placed inside the placement groove. The thermal insulation cotton is glass fiber thermal insulation cotton. The thermal insulation cotton inside the placement groove can effectively insulate the temperature of the transported medium in the pipeline.

[0009] Furthermore, it also includes a corrosion-resistant layer and a protective metal mesh. The corrosion-resistant layer is coated on the inner wall of the pipe body, and the protective metal mesh is fixed on the outer side of the thermal insulation cotton. The corrosion-resistant layer is a perfluoropolyether coating. The corrosion-resistant layer can protect the corrosive substances in the conveying medium, and can increase the service life of the pipe body in combination with the protective metal mesh.

[0010] Furthermore, it also includes a fixed cover and a sealing adhesive, one end of the fixed cover is connected to the top surface of the tube body, and the bottom surface of the fixed cover is fixed with the sealing adhesive, which fixes the fixed cover to the top surface of the injection port, thereby preventing debris from entering after injection is completed.

[0011] Furthermore, it also includes a protective sleeve, which is sleeved on the outside of the pipe body. The protective sleeve is made of high-density polyethylene. The sleeved protective sleeve can effectively protect the pipe body and has a cold-resistant effect.

[0012] Furthermore, it also includes a wear-resistant coating, which is evenly coated on the outer side of the protective sleeve. The wear-resistant coating is a polyurethane coating. The wear-resistant coating can effectively prevent external objects from rubbing against the pipe body to prevent wear on the surface of the pipe body.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. Connect the output end of the external welding machine through the electrical connector, so that both sides of the pipe body are melted and fixedly bonded to the outside of the pipe. When the pipe body melts, the identification column extends out to facilitate personnel to judge the stability of the pipe body fixation. The limit baffle can effectively limit the distance between the pipe body and the pipe interface. The set injection port can inject different types of foaming materials according to different usage conditions to ensure the sealing of the pipe interface.

[0015] 2. By placing the insulation cotton inside the groove, the temperature of the conveying medium in the pipeline can be effectively insulated. The sleeved protective sleeve can effectively protect the pipe body and has the effect of cold resistance. The corrosion-resistant layer can protect the corrosive substances in the conveying medium. The protective metal mesh can increase the service life of the pipe body. BRIEF DESCRIPTION OF THE DRAWINGS
