To reach above-mentioned purpose, the utility model states a kind of shockproof special electric thermo-couple of high temperature, including terminal box, in wiring
The side of box is equipped with the first interface for threading, and the second interface for being used for interting thermocouple core is equipped with the lower end of terminal box,
Its key is：The second interface is connected by the upper end of connector and protection pipe, and corundum is arranged with the protection pipe
Pipe, high temperature adhesive is filled between the outer wall of alundum tube and the inner wall of protection pipe, is set in the tube chamber of the alundum tube
There is inner core tube, the upper end of the inner core tube is penetrated in the connector, and in the thermocouple core in inner core tube and the terminal box
Wire connection terminal be electrically connected, be also welded with ring flange on the outer wall in the middle part of the tube body of the protection pipe.
Based on above-mentioned design, protection pipe can be integrally formed, it is thus only necessary to which upper end is connected and sealed, good airproof performance, knot
Structure is simple, easy for installation, carries out double shielding plus alundum tube and high temperature adhesive so that thermocouple core is at one
In the working environment of safety and stability, influence of the environmental factor to its measurement accuracy can be effectively avoided, integrated connection portion is few, in addition
The material of protection pipe can use noble metal or high-strength alloy to form, and have good shockproof effect.
Further, in order to ensure sealing performance, the connector is threaded connector, the upper end of the connector with it is described
Second interface is using being threadedly coupled, and the lower end of the connector is socketed the protection pipe and by welded seal, on the connector
It is additionally provided with locking nut.
Further, tube body loosens in order to prevent, a circle boss is equipped with the inner wall of the connector, under the boss
End face and the upper surface of the protection pipe abut against.
Further, the length of the connector is 30mm, and the lower face of the boss is from the connector lower end port
The distance at edge is 10mm.
Further, connected applications need, and the outside diameter of the protection pipe is 30mm.
The remarkable result of the utility model is：It is multi-level by setting protection pipe, alundum tube and high temperature adhesive to carry out
Sealing protection, avoid thermocouple core from directly being contacted with high temperature, high pressure and sour environment, extend the service life of equipment；
It is easy for installation meanwhile pipe structure is simple, it is thus only necessary to which that the connector of upper end is attached sealing, can avoid loosening, effectively
It is shockproof.
