Description
Technical Field
The utility model relates to a sealing device, in particular to a furnace thermocouple sealing device.
Background
The temperature of industrial furnaces and heating furnaces is measured by thermocouples which are generally installed in a mode of no fixed pressing or flange fixing and the like.
The thermocouple sealing adopts V-shaped sealing at present, the conical surface sealing replaces the traditional plane sealing, the traditional plane sealing is improved, the sealing contact area is increased compared with the plane sealing, the pressing effect is improved, and the thermocouple is not easy to vibrate.
However, when the high-temperature sealing heat-insulating rope is wound on the conical surface, the heat-insulating rope is easy to slide towards the lower end when being wound, and the heat-insulating rope can be extruded downwards to move when being installed and compressed, so that the sealing heat-insulating rope on the contact surface is loose. The sealing defect on the conical surface causes poor sealing and heat-insulating effects of the thermocouple and leakage of high-temperature gas.
SUMMERY OF THE UTILITY MODEL
The technical task of the utility model is to provide a furnace thermocouple sealing device aiming at the defects of the prior art, the winding heat preservation rope cannot move on the V-shaped conical surface through the structural improvement of the V-shaped conical surface, the heat preservation rope is flattened and cannot be scattered when the conical body is compressed to form a sealing surface, and the thermocouple sealing and heat preservation effect is good.
The technical scheme for solving the technical problem is as follows: the utility model provides a kiln thermocouple sealing device, includes the sealed frustum of V type, its characterized in that: the V-shaped sealing frustum is placed in the protective sleeve; the sealing convex conical surface of the V-shaped sealing frustum is provided with a plurality of circles of grooves; the protective sleeve comprises an annular top platform, a funnel sleeve and a sleeve.
The top surface of the V-shaped sealing frustum is provided with a flange, and the V-shaped sealing frustum is connected with the annular top platform of the protective sleeve through the flange.
The multi-turn groove is spiral.
The cross section of the groove is 1/4 circular arcs.
The protective sleeve is provided with a mounting base.
Compared with the prior art, the utility model has the following outstanding beneficial effects:
1. the V-shaped convex conical surface device is convenient and quick to wind the heat preservation rope;
2. the heat-insulating rope is not easy to loosen;
3. the heat preservation rope is flattened and then does not move, the sealing performance is good, and the heat preservation effect is good.
