When typically use thermocouple temperature measurement below 1000 °C, and more than 1000 °C after switch to infrared radiation thermometer thermometric so that right
Product temperature in thermal field carries out temperature measurement and control.In traditional low temperature thermometric, thermocouple is in stationary state, so
If when temperature is too high in thermal field, thermocouple can be impacted, easily cause the result that thermocouple is burnt out, and use W-Re
On the one hand the more preferable thermocouple of the performances such as thermocouple considerably increases cost, and the ceramic thermal insulation set of outer layer is due to its fragility in addition,
Damaged in collision is easily caused, so as to considerably increase maintenance cost and use cost.
The content of the invention
It is an object of the invention to provide a kind of simple and practical, strong operability, the high temperature resistance furnace that can protect thermocouple
Low temperature temperature measuring mechanism.
In order to realize foregoing invention purpose, the utility model uses technical scheme as described below：
A kind of low temperature temperature measuring mechanism of high temperature resistance furnace, including support, Rodless cylinder, slip blade, temperature thermocouple, stretch
Contracting bellows and graphite-pipe, the L shapes that support is made up of horizontal side plate and the connection of vertical side plate, set in the upper surface of horizontal side plate
It is equipped with Rodless cylinder, Rodless cylinder and is fixedly connected with slip blade, one end of the expansion corrugated pipe is connected to slip blade
On, the other end of expansion corrugated pipe is connected on the one side of vertical side plate, and the another side of vertical side plate is connected with hollow
Graphite-pipe, the inner chamber of graphite-pipe is connected with the inside of expansion corrugated pipe, and the central axis and expansion corrugated pipe of graphite-pipe
Central axis overlap, one end of described temperature thermocouple is connected on slip blade, and the other end of temperature thermocouple is passed through
Stretched into after expansion corrugated pipe in graphite-pipe.
Further, the graphite-pipe is spun by screw thread by two sections of graphite bodys and constituted.
Further, it is arranged with thermal insulation ceramicses set at the position of vertical side plate on the outer wall of graphite-pipe.
Due to using above-mentioned technical proposal, the utility model has following superiority：
The utility model can realize cold stage thermometric control in the case where keeping body of heater vacuum or inert gas shielding state
System and hot stage switching are exited, it is achieved thereby that function, also protects temperature thermocouple so that thermocouple is not chronically at
Under the condition of high temperature, the service life of thermocouple is extended, failure loss ratio has been greatly reduced, has reduced entreprise cost.

Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described in detail to the technical solution of the utility model.
As shown in figure 1, a kind of low temperature temperature measuring mechanism of high temperature resistance furnace, including support 2, Rodless cylinder 1, slip blade 7,
Temperature thermocouple 6, expansion corrugated pipe 5 and graphite-pipe 4, the L shapes that support 2 is made up of horizontal side plate and the connection of vertical side plate,
The upper surface of horizontal side plate, which is provided with Rodless cylinder 1, Rodless cylinder 1, is fixedly connected with slip blade 7, the expansion corrugated pipe
5 one end is connected on slip blade 7, and the other end of expansion corrugated pipe 5 is connected on the one side of vertical side plate, vertical side plate
Another side be connected with hollow graphite-pipe 4, the inner chamber of graphite-pipe 4 is connected with the inside of expansion corrugated pipe 5, and graphite
The central axis of pipe 4 is overlapped with the central axis of expansion corrugated pipe 5, and one end of described temperature thermocouple 6 is connected to slip support
On plate 7, the other end of temperature thermocouple 6 is stretched into graphite-pipe 4 after passing through expansion corrugated pipe 5.
According to the length of actual temperature thermocouple 6, the graphite-pipe 4 is spun group by screw thread by two sections of graphite bodys
Into, by adjusting the length of graphite-pipe with adapt to temperature thermocouple,
Thermal insulation ceramicses set is arranged with the position of vertical side plate on the outer wall of graphite-pipe, collet insulator is used to protect
Structure composition of the present utility model is protected not by high temperature failure.
The effect of described expansion corrugated pipe 5 is in order that support keeps body of heater vacuum or inert gas after being connected with body of heater
Guard mode.
The utility model in specific application, the vertical side plate of support is connected by body of heater flange with body of heater, graphite-pipe
Static to be in thermal field, the end of probe of temperature thermocouple is located in graphite-pipe, and now expansion corrugated pipe is in compressive state；Work as stove
During internal heater heat temperature raising, temperature thermocouple is measured and controlled to the temperature in thermal field by measuring the temperature of graphite-pipe
System；When temperature of thermal field is close to 1000 °C, thermometric mode is switched over, and being changed into infrared radiation thermometer by thermocouple temperature measurement mode surveys

Thermal field occasionally is exited, in off working state, thermocouple end of probe is away from high temperature thermal field area, so that temperature thermocouple is protected, it is complete
Low temperature thermometric into the temperature rise period works；When body of heater thermal field cools, when temperature is in less than 1000 °C, thermometric mode is carried out
Switching, is changed into thermocouple temperature measurement mode, now Rodless cylinder is acted by infrared radiation thermometer thermometric, drives slip blade to enter
Line position is moved, and expansion corrugated pipe is in compressive state, and temperature thermocouple puts in thermal field, in running order, and thermocouple end of probe is leaned on
Nearly high temperature thermal field area, thermometric and control are carried out to high temperature thermal field, are finally completed the low temperature thermometric work of temperature-fall period.
The utility model realized in the case where keeping body of heater vacuum or inert gas shielding state the control of cold stage thermometric and
Hot stage switching is exited, it is achieved thereby that function, also protects temperature thermocouple so that thermocouple is not chronically at high temperature
Under state, the service life of thermocouple is extended, failure loss ratio has been greatly reduced, has reduced entreprise cost.
