Abstract
The present invention provides a thermal resistor protective structure which comprises a protective sleeve tube and a connection piece. The protective sleeve tube comprises a sleeve tube body, a connection flange and an end cover. One end of the sleeve tube body is closed, the other end is provided with an internal thread, and the length of the protective sleeve tube is smaller than that of a thermal resistor. The connection end of the connection flange is provided with a sealing groove, and the inner wall is connected to the sleeve tube body. The end cover is provided with an outer thread and is matched with the inner thread, and the end cover is connected to the tail end of the thermal resistor. The connection piece comprises a tube body and a matched flange. Two ends of the tube body are not closed, one end communicates with a container, the other end communicates with the matched flange, and the inner diameter of the tube body is larger than the outer diameter of the sleeve tube body. The structure of the thermal resistor protective structure is simple, through arranging the protective sleeve tube and allowing the length of the protective sleeve tube to be smaller than that of the thermal resistor, thus the thermal resistor is directly in contact with the head of the protective sleeve tube and a side wall, and thus an accurate value can be rapidly obtained. In addition, the outer diameter of the sleeve tube body is smaller than the inner diameter of the connection piece, and the maintenance personnel can easily take the thermal resistor protective structure and the thermal resistor out.

[embodiment]
Below in conjunction with the drawings and specific embodiments, a kind of thermal resistance operator guards of the present invention is described further.
Refer to Fig. 1, in a better embodiment of the present invention, a thermal resistance operator guards comprises protective casing 1 and web member 2.
Described protective casing 1 comprises sleeve body 11, joint flange 12 and end cap 13.Described sleeve body 11 is a hollow circular cylinder, and one end is closed, and the other end is provided with internal thread, and length is less than required length of installing thermal resistance 3.Described joint flange 12 is welded on the outer wall of described tapped one end of sleeve body 11, coaxial with described sleeve body 11, and offers connecting hole 14.Described joint flange 12 also offers the seal groove 15 of mounting O-shaped rings at link.Described end cap 13 is provided with the external thread with described screw-internal thread fit, and welds together with described thermal resistance 3, for preventing air and the outside air convection current of described sleeve body 11 inside.Preferably, the length of described sleeve body 11 adds the length that diameter is less than described thermal resistance 3; Described sleeve pipe 1 is made up of alkaline-resisting stainless steel.Especially, described sleeve pipe 1 is made up of 316 stainless steels.
Described web member 2 comprises body 21 and coordinates flange 22, and described body 21 two ends are not closed, and one end is communicated with container 4 inside of tested slip 5, and the other end is communicated with described cooperation flange 22, and the internal diameter of described body 21 is greater than the external diameter of described sleeve body 11.Described cooperation flange 22 welds with described body 21 and coaxial, and abutting end offers the mating groove 23 onesize with the seal groove 15 of described joint flange 12 link.Especially, described cooperation flange 22 offers mating holes 24, corresponding with the connecting hole 14 of described joint flange 12.
During use, described web member 2 is welded on described container 4, O-ring seal is placed in described seal groove 15 and described mating groove 23, bolt can lock described connecting hole 14 and described joint flange 12 links together with the described flange 22 that coordinates by described mating holes 24, the described the slip 5 and blind end of described sleeve pipe 11 submerges, then screws in the end cap 13 with described thermal resistance 3 in sleeve body 11.The length being now greater than described sleeve body 11 due to the length of described thermal resistance 3 adds diameter, therefore described thermal resistance 3 in described sleeve body 11 by bending and head and side contact with described sleeve body 11, make described thermal resistance 3 promptly can measure the temperature of described sleeve body 11.Again because the making material of described sleeve body 11 is stainless steel, coefficient of heat conductivity is larger, therefore can think the temperature of described sleeve body 11 inwall and the suitable of described tested slip 5.So the error of the temperature measured by described thermal resistance 3 is within allowed band.
During taking-up, the diameter due to described sleeve body 11 is less than the diameter of described body 21, even if the diameter increasing described sleeve body 11 that scabs on described sleeve body 11 surface also can easily take out, and the impact do not scabbed.
Structure of the present invention is simple; convenient making; by arranging protective casing 1; and make the length of protective casing 1 be less than the length of described thermal resistance 3; and described thermal resistance 3 is connected with the end cap 13 of cannula end; the head of described thermal resistance 3 and described protective casing 1 and sidewall are directly contacted, adds the strong and resistance to highly basic of the stainless-steel tube capacity of heat transmission, thus can promptly obtain numerical value accurately in the environment of high temperature, high pressure, highly basic.And the external diameter due to described sleeve body 11 is less than the internal diameter of described web member 2, maintainer can take out the cleaning that thermal resistance operator guards and described thermal resistance 3 carry out scabbing like a cork.
Above-mentioned explanation is the detailed description for the better possible embodiments of the present invention, but embodiment is also not used to limit patent claim of the present invention, the equal change completed under technical spirit suggested by all the present invention or modification are changed, and all should belong to the present invention and contain the scope of the claims.
