Summary of the invention
The purpose of this utility model provides a kind of electric heater for pipeline that need not medium.
To achieve these goals, the utility model is by the following technical solutions:
A kind of buried pipeline heating equipment, it is underground by placing, be sheathed on the electric heater of pipeline outside and be used for this electric heater is formed with the belted type cable that power supply on the ground is communicated with; Described electric heater is made up of the housing and the inner electrothermal device of outside; Described housing is the tubulose of hollow, and the outer wall of its inwall and pipeline is fitted; In the cavity of described electrothermal device between this tubular shell inside and outside wall, be made of several heating watt and the parallel conducting wire that connects this each heating watt, described each heating watt is attached at the inwall of described housing; Described belted type cable joins by glue sealing joint and this housing, and is communicated with each lead of described parallel connection.
Aforesaid buried pipeline heating equipment wherein, is filled with thermal insulation layer in the cavity between the described housing inside and outside wall.
Aforesaid buried pipeline heating equipment, wherein, the outer surface of described housing scribbles anticorrosive coat.
Aforesaid buried pipeline heating equipment, wherein, the two ends of described housing are provided with flange.
Aforesaid buried pipeline heating equipment, wherein, two end part in the cavity between the described housing inside and outside wall are provided with the thermocouple that is used for measuring channel inlet temperature and measuring channel outlet temperature respectively, and described thermocouple joins by compensation lead of thermocouple and belted type cable.
Aforesaid buried pipeline heating equipment, wherein, described thermocouple preferably is located on the inner walls that is in the pipeline below.
Aforesaid buried pipeline heating equipment wherein, is provided with the overheat protector point for measuring temperature in the cavity between the described housing inside and outside wall, and described overheat protector point for measuring temperature joins by lead and belted type cable.
