。它包括有一个平直的管壳,管壳中心安置有一个绝缘中心套,管壳一端封闭、一端开口;一根电热丝从管壳的开口端穿入并从绝缘中心套一端穿入绝缘中心套,再从绝缘中心套另一端穿出,然后螺旋绕在绝缘中心套外壁上,最终回到管壳的开口端,从而在管壳的开口端形成一个进线端和一个出线端;在绝缘中心套外壁及螺旋状电热丝外围填充有氧化镁粉;管壳的开口端由密封件密封。本发明可在直管式的电加热管上实现单端进、出线,其结构简单紧凑、空间占用小;同时往复的电热丝可在绝缘中心套内、外得到可靠定位支撑,保证了其运行的可靠性。
The invention relates to an electric heating device, in particular to a single end import line straight rod type electric heating tube. It comprises a shell and a straight, the center of the pipe shell is provided with a set of Insulation Center, shell and tube closed at one end, one end opening; a heating wire from the open end of the shell and tube inserted and insulating center set from the insulating center sleeve is penetrated, and from the other end insulation center set out, and then spiral around insulation center sleeve outside, eventually return to the open end of the tube shell, the shell and tube open end to form an inlet and an outlet in the center of the outer wall of the outer sleeve; the insulation and spiral heating wire peripheral magnesium oxide powder is filled; the opening end of shell and tube is sealed by a sealing member. The invention can be in the straight tube type electric heating tube for single terminal, terminal, simple and compact structure, small space occupation; at the same time, the heating wire reciprocating in insulating center sleeve, has reliable positioning support, to ensure the reliability of its operation.
