The invention relates to the field of sealing devices, and discloses a steel-plastic composite pipe end face sealing device. Aiming at the problem that the steel-plastic composite pipe section is easily corroded in the prior art, the following scheme is proposed, which includes a base, and the base One side of the top is fixed with a fixed seat, and the top of the fixed seat is provided with a moving groove, and the inner part of the moving groove is connected with a threaded column, the threaded column is a two-way threaded column, and the external thread of the threaded column is connected with two moving blocks. The two moving blocks are respectively connected with two opposite threads on the outside of the threaded column, the top of the fixed base is slidably connected with two splints, and the tops of the two moving blocks are respectively fixedly connected with the bottoms of the two splints. The invention has the advantages of reasonable structure, simple operation and ingenious design. By heating and pressurizing the end surface of the pipe material and then sealing the metal layer, the purpose of sealing the end surface of the pipe material and preventing it from being corroded is achieved.
Description
technical field [0001] The invention relates to the field of sealing devices, in particular to a steel-plastic composite pipe end face sealing device. Background technique [0002] Steel-plastic composite pipes are widely used in the modern construction industry. Due to reasons such as production, storage, transportation, installation and use, each pipe should not be too long, which requires that the quality of the end face of the pipe must be guaranteed throughout the process from production to use. There is no effective measure to ensure that the end face is not corroded in the industry, and there is a hidden danger, that is, the quality problems of pipes are easily caused by corrosion from production to use. In order to avoid this result, it is necessary to design a steel-plastic composite pipe end face sealing device. Contents of the invention [0003] The end face sealing device of the steel-plastic composite pipe proposed by the invention solves the problem that the...
