Description

Technical Field

[0001] The utility model relates to the technical field of pipe fittings, in particular to a plastic-coated electric fusion pipe fitting. Background Art

[0002] At present, pipes are often connected by pipe fittings. The existing connection methods are mostly threaded connection, welding connection or compression connection, which have many defects: for example, the sealing performance of threaded connection is poor, and the slip of thread buckle easily causes the pipe fitting to fail to connect; welding connection has high requirements on operators and operating equipment, and welding connection also has the risk of damaging pipe fittings; compression connection requires high-intensity compression of pipe fittings, causing them to deform and connect to pipes, which is also easy to cause damage to pipe fittings.

[0003] Another connection method is to use hot melt connection, which uses an external heat source to heat the pipe so that the end of the pipe is melted and then directly connected. In the hot melt connection process, a hot melt welding machine is usually used to heat the butt surface of the pipe through a heating plate. When a certain temperature is reached, the pipe melts and is connected together under pressure, and then cools and solidifies to form a complete connection. However, the inventor found that using a hot melt welding machine to operate hot melt connection is still cumbersome, and the construction area is limited by the equipment, which is not conducive to the rapid connection between pipes. For this reason, the utility model proposes a plastic-coated electric fusion pipe fitting. Utility Model Content
