With the service life, the cost of enterprise is saved.
In order to achieve the above object, the technical solution adopted in the utility model is: it includes thermometric end and display end, thermometric end
Including outside protective case, internal protective cover pipe and thermocouple wire, outside protective case is made of high temperature resistant, wear-resistant material, interior protection
The upper end of casing is provided with circular hole, and the lower end of internal protective cover pipe is provided with pouring hole, is not communicated between circular hole and pouring hole, interior guarantor
The lower end of protecting pipe and be located at pouring hole side wall on be uniformly arranged multiple through-holes, thermocouple wire is interspersed in circular hole, interior guarantor
Protecting pipe is co-axially located in outside protective case；The thread segment activity of internal protective cover pipe lower end passes through the bottom of outside protective case
Afterwards, high temperature resistant filler material is cast in the space between internal protective cover pipe and outside protective case by pouring hole and is sealed；
After the completion of the injection molding of high temperature resistant filler material, thread segment is connect with the internal screw thread in end cap.
Further, the upper end of thermometric end is provided with flange.
Further, end cap is made of high temperature resistant, wear-resistant material.
Further, after end cap is connect with thread segment, pass through laser welding at the gap of end cap and thread segment.
The utility model has the beneficial effects that the utility model provides a kind of high-temp. wear-proof thermo-couple, structure is simple, is easy to
Processing when detecting under high temperature environment, has wear-resisting, the characteristics such as high temperature resistant, while can prevent from bursting, improves thermocouple
Service life saves the cost of enterprise.
