Abstract

The invention relates to a fusing type electric heating pipe fitting, which comprises a tubular body, the outer wall of the tubular body is provided with a terminal post and an observation post, and a spirally wound resistance wire is embedded in the tube wall of the tubular body, and the resistance wire The wire is electrically connected to the terminal post, and the inner wall of the tubular body is provided with an annular limiting boss; the resistance wire includes a first resistance wire and a second resistance wire, and the diameter of the first resistance wire is larger than the The diameter of the second resistance wire, the first resistance wire is wound on both sides of the annular limiting boss, the second resistance wire is wound in the middle of the tubular body and connected to the annular limiting boss Corresponding. The fuse-type electric heating melting pipe fitting proposed by the present invention changes the resistance wire in the middle of the electric heating melting pipe fitting into a thinner wire, so that the current can be well controlled to be fused at a specific current, and the resistance wire is broken and cannot continue to heat, thus avoiding the current Too big a problem.

Description

Technical field [0001] The invention belongs to the technical field of electrothermal fusion pipe fittings, and particularly relates to a fuse type electrothermal fusion pipe fitting. Background technique [0002] Electric melting pipe fittings are connected to the pipeline by heat melting. The heating source is the copper wire wound in the electric melting pipe fittings. The copper wire is energized through both ends, and the current passes through the copper wire to generate heat, thereby melting the pipes and pipe fittings. When the copper wire is energized, it needs to be adjusted according to the pipes of different calibers, and three stages of energization are required, that is, the first stage is preheated, the second stage is heated, and the third stage is hot melted. [0003] Different currents and voltages are required in different stages. Generally, there will be no problems in the first and second stages, but problems may occur in the third stage, such as the displacem...
