Abstract

The utility model relates to an anti-leakage type radiation electrothermal tube, wherein a pressure-bearing chamber is arranged between an electrothermal tube and a junction box. The connection part of the pressure-bearing chamber and the junction box is provided with a pressure-bearing insulated electrical connector. The two ends of the pressure-bearing insulated electrical connector are positioned in the pressure-bearing chamber and the junction box respectively. The pressure-bearing insulated electrical connector is connected with a terminal via a cable. Due to the arrangement of the pressure-bearing chamber between the electrothermal tube and the junction box, the electrothermal tube and the junction box are separated from each other. Thus, when the leakage caused by corrosion or electric breakdown occurs at one side of the electrothermal tube provided with the terminal, the medium in the electrothermal tube leaks into the pressure-bearing chamber. The connection part of the pressure-bearing chamber and the junction box is provided with the pressure-bearing insulated electrical connector and the pressure-bearing insulated electrical connector is connected with the terminal via a cable. Therefore, the pressure-bearing chamber is isolated from the outside, while the normal connection of the power supply is ensured at the same time. In this way, the medium does not enter an external heating area, so that the external heated materials are not polluted by the medium.

Description

Anti-leak formula radiation electric heat pipe
Technical field:
The utility model patent relates to a kind of radiation electric heat pipe, particularly is provided with pressure pocket between a kind of electrothermal tube and terminal box, can be used for the anti-leak formula radiation electric heat pipe of pressure-bearing occasion.
Background technology:
Common radiation electric heat pipe adopts outer tube, heating wire and insulating porcelain piece to combine, heat energy passes through the outside radiant transfer of electrothermal tube outer wall by heating wire, this electrothermal tube has the high characteristics of heatproof, but when electrothermal tube leaks (such as corrosion or electrical breakdown), medium will enter operational environment, cause the accident, can not be used for the pressure-bearing occasion.
The utility model content:
The purpose of the utility model patent is to provide between a kind of electrothermal tube and terminal box and is provided with pressure pocket, can be used for the anti-leak formula radiation electric heat pipe of pressure-bearing occasion.
To achieve these goals, the utility model proposes following technical scheme realizes:
Anti-leak formula radiation electric heat pipe is drawn rod, terminals, fiber thermal insulation board, cable access, is filled the nitrogen mouth and form by terminal box, pressure pocket, pressure-bearing insulated electro joint, electrothermal tube, container, process flange, heating wire, ceramic supporting element, electrode; Terminal box is provided with cable access, fills the nitrogen mouth; Electrothermal tube and process flange welding, and insert in the container; Be provided with ceramic supporting element, heating wire, electrode in the electrothermal tube and draw rod, fiber thermal insulation board, electrode draws an excellent end and is provided with terminals, electrode draws rod and passes the fiber thermal insulation board and connect heating wire at the other end, heating wire from close silk to rare layout, is provided with ceramic supporting element according to the flow direction of medium between heating wire; It is characterized in that: be provided with pressure pocket between electrothermal tube and terminal box, pressure pocket and terminal box connecting portion are provided with pressure-bearing insulated electro joint, and pressure-bearing insulated electro joint two ends lay respectively in pressure pocket, the terminal box, and pressure-bearing insulated electro joint is connected with terminals by cable.
The soluble technical problem of the utility model patent is:
When anti-leak formula radiation electric heat pipe is worked in the pressure-bearing environment, owing to be provided with pressure pocket between electrothermal tube and terminal box, so that electrothermal tube separates with terminal box, cause electrothermal tube when being provided with terminals one side generation leakage when corrosion or electrical breakdown occurring, the dielectric leakage in the electrothermal tube advances pressure pocket; Pressure pocket and terminal box connecting portion are provided with pressure-bearing insulated electro joint, pressure-bearing insulated electro joint is connected with terminals by cable, when having guaranteed the normal connection of power supply, so that pressure pocket is with outside isolated, medium can not enter the external heat zone, and heated material is polluted.
Description of drawings:
Fig. 1 is the utility model structure chart.
Embodiment:
As shown in the figure, anti-leak formula radiation electric heat pipe is drawn rod 9, terminals 10, fiber thermal insulation board 11, cable access 12, is filled nitrogen mouth 13 and form by terminal box 1, pressure pocket 2, pressure-bearing insulated electro joint 3, electrothermal tube 4, container 5, process flange 6, heating wire 7, ceramic supporting element 8, electrode; Terminal box 1 is provided with cable access 12, fills nitrogen mouth 13; Electrothermal tube 4 and 6 welding of process flange, and insert in the container 5; Be provided with ceramic supporting element 8, heating wire 7, electrode in the electrothermal tube 4 and draw rod 9, fiber thermal insulation board 11, electrode draws rod 9 one ends and is provided with terminals 10, electrode draws rod 9 and passes fiber thermal insulation board 11 and connect heating wire 7 at the other end, from close silk to rare layout, 7 of heating wire are provided with ceramic supporting element 8 to heating wire 7 according to the flow direction of medium; 1 of electrothermal tube 4 and terminal box are provided with pressure pocket 2, and pressure pocket 2 is provided with pressure-bearing insulated electro joint 3 with terminal box 1 connecting portion, and pressure-bearing insulated electro joint 3 two ends lay respectively in pressure pocket 2, the terminal box 1, and pressure-bearing insulated electro joint 3 is connected with terminals 10 by cable.
In when work, if electrothermal tube 4 leaks because corrosion or electrical breakdown cause being provided with terminals 10 1 sides, because electrothermal tube 4 and 1 of terminal box are provided with pressure pocket 2, so that electrothermal tube 4 separates with terminal box 1, electrothermal tube 4 interior dielectric leakages advance pressure pocket 2; Pressure pocket 2 is provided with pressure-bearing insulated electro joint 3 with terminal box 1 connecting portion, pressure-bearing insulated electro joint 3 is connected with terminals 10 by cable, when having guaranteed the normal connection of power supply, so that pressure pocket 2 is with outside isolated, medium can not enter the external heat zone, and heated material is polluted.
The utility model can play in the pressure-bearing environment and prevent that the situation that medium occurs to leak in the electrothermal tube from occuring, and has good promotional value.
