And a metal net-free area with the same width as the heat shrinkage sleeve is reserved in the middle of the heating metal net.
The metal net-free area is reserved in the middle of the heating metal net to prevent heat generated by the heating metal net from damaging the sealing performance of the heat shrinkable sleeve.
The novel connection mode that the reinforced electric hot melting belt is connected with the plastic pipeline is as follows: the heat shrinkable sleeve is preset at the butt joint of the pipeline, then the lap joint of the reinforced electric hot melting belt is coated outside the heat shrinkable sleeve, and the heat shrinkable sleeve is welded on the outer wall of the pipeline by electrifying and heating.
The heat shrinkable sleeve is preset at the butt joint of the pipelines and used for solving the sealing problem of butt joint of the pipelines and eliminating the risk of leakage of the butt joint when an electric hot melting belt is sealed. The reinforced electric hot melting belt is lapped and coated outside the heat shrinkage sleeve, and is welded on the outer wall of the pipeline by electrifying and heating, so that the sealing strength is provided for the heat shrinkage sleeve, and the axial force for pipeline connection is provided.
Compared with the prior art, the invention has the following advantages:
1. by adding the preset heat shrinkage sleeve, the steps of manual repair welding butt joint and repair welding lap joint of the electric hot melting belt are eliminated, and the connecting efficiency and the welding quality are improved.
2. The metal net-free area with the same width as the heat shrinkable sleeve is reserved in the middle of the heating metal net of the electric hot melting belt, so that the heat generated by the heating metal net is prevented from damaging the sealing property of the heat shrinkable sleeve.
