Novel temperature controlled electric heating tube

Abstract

The invention provides a novel temperature controlled electric heating tube which is simple in structure and reasonable in design. One end of the novel temperature controlled electric heating tube serves as a mounting end, the other end of the novel temperature controlled electric heating tube serves as a fixed end; a mounting nut and a locking thread are arranged at the mounting end, so that mounting and clamping are facilitated, the integral locking effect is better, and the phenomenon of flaking off is avoided; moreover, the mounting nut adopts a regular hexagon structure, so that the stress is more uniform, and time and labor are saved; a temperature controller is arranged in the fixed end, the highest temperature of the temperature controller is kept as 110 DEG C, and temperature is limited automatically when exceeding the highest temperature, so that temperature is prevented from exceeding a rated value, and the heating pipe is protected. The novel temperature controlled electric heating tube has the advantages that the electric power is saved; the service life of the product is prolonged; the cost is reduced; requirements of manufacturers can be met.

Description

technical field [0001] The invention relates to the technical field of electric heating tubes, in particular to a novel temperature-controlled electric heating tube. Background technique [0002] The electric heating tube is a tubular electric heating element, which is composed of a metal tube spiral resistance wire and crystalline magnesium oxide powder. The high temperature resistance wire is evenly distributed in the stainless steel seamless tube, and the crystalline magnesium oxide powder with good thermal conductivity and insulation performance is filled in the gap. The structure is not only advanced, but also has high thermal efficiency and uniform heating. The heat diffuses to the surface of the metal tube through the magnesium oxide powder, and then transfers to the heated part or the air to achieve the purpose of heating. When the existing electric heating tube is working, the temperature cannot be controlled and often exceeds its own temperature. The heating tube ...
