Abstract

The invention provides a side joint pillar type electric melting pipe fitting which comprises a pipe body, at least two connector lugs, a first hot melting type material layer and a first electric heating wire. The connector lugs are arranged on the end face wall of the end heads. The first hot melting type material layer is at least locally fixed to the inner side wall and / or the outer side surface. The first electric heating wire is fixed in the first hot melting type material layer. The two ends of the first electric heating wire are electrically connected with the connector lugs correspondingly. The connector lugs of the side joint pillar type electric melting pipe fitting are installed on the end face wall of the pipe body, the connector lugs can be inserted in an insertion piece to achieve butt joint positioning and fixing effects, the maximum outer diameter of the electric melting pipe body is smaller (the height of the connector lugs which are arranged in the radial direction does not exist), and the space occupied by the whole electric melting pipe body is reduced.

Description

technical field [0001] The invention relates to the field of electric fusion pipe fittings, in particular to a side column type electric fusion pipe fitting. Background technique [0002] At present, electrofusion pipe fittings refer to pipe fittings that use the high temperature generated by electric current to melt multiple polyethylene pipe fittings that are in contact with each other and connect them together. Compared with traditional pipe fittings, such as threaded connections and plug-in connections, due During the connection process, it is necessary to rotate or apply force to the pipe fittings. For some large pipe fittings, the on-site construction operation is very difficult. The electrofusion connection method has outstanding advantages in construction engineering. For polyethylene pipe fittings, the use of electrofusion welding technology can easily Connect the two fittings. [0003] In recent years, electrofusion pipe fittings have been widely used in the field...
