Description

Non-metal pipeline welding device Technical Field The utility model belongs to the technical field of pipeline butt joint devices, and particularly relates to a nonmetal pipeline welding device. Background Non-metallic pipes, such as polyethylene, polyvinyl chloride, polypropylene pipes, etc., require heating the pipe connection ends to the melting temperature of the material during pipe installation, and then butt-jointing the melted pipe connection parts until the butt-jointed melting parts of the pipes are coagulated and solidified to adapt to the actual pipe installation length. The problem encountered in the actual welding process of the nonmetallic pipe fitting is that the nonmetallic polyethylene and the polyvinyl chloride can generate combustible harmful gases such as methane, ethylene, benzene and the like in the heating process, and particularly under the narrow and closed welding environment, the combustible gases are emitted to the outside to gather to reach a certain concentration, so that the risk of explosion exists. Disclosure of utility model In order to solve the problems in the prior art, the application provides a non-metal pipe welding device for avoiding the risk of explosion of non-metal pipe fittings in the welding process. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a nonmetal pipeline fusion device, includes the shell, the shell both ends are provided with the jack, the shell middle part is provided with the welding subassembly, the both ends outer wall of welding subassembly pass through the connecting block with the shell inner wall is connected, shell upper portion is provided with the apron, the shell bottom is provided with the air cavity, the air cavity is linked together with the shell is inside through the air duct, shell lateral wall bottom is provided with water intaking valve and play water valve respectively, the water intaking valve through the cooling tube that sets up in the shell with it is linked together to go out the water valve, the gas outlet orientation of air duct the cooling tube, shell lateral wall upper end is provided with the blast pipe. In one embodiment of the application, an arc-shaped support plate is arranged on the outer side of the jack. In one embodiment of the application, a soft rubber ring is arranged in the jack.
