Abstract
The utility model discloses a kind of thermocouple ga (u)ge dual-thread seal joint, comprise extruding external member and gland nut, be provided with in described gland nut and the inner chamber extruding external member and coordinate, the upper part of described extruding external member and inner chamber closely cooperates, the intracavity sidewall of described gland nut is provided with a groove, the lateral wall of described extruding external member is provided with and is fixed with a metal bar, and described metal bar is embedded in groove, makes can not produce relative rotation between extruding external member and gland nut.In gland nut assembling rundown process, the compression external member of joint inside can not produce relative rotation, be used for preventing thermo-electric metal line through gland nut and and nut is tightened time External Force Acting that thermocouple wire is brought, tinsel is made to tie a knot or twist off, greatly reduce in assembling thermopair process, the loss that manual operation brings thermocouple wire, significantly reduces the production cost of enterprise.
Description
Technical field
The utility model relates to a kind of Thermocouples Technology field, and particularly one is for the production of preparing thermocouple ga (u)ge dual-thread seal joint.
Background technology
Thermopair is temperature element conventional in temperature measuring instrument, its direct measuring tempeature, and temperature signal is converted to thermopower signal, is converted to the temperature of measured medium by electric meter (secondary instrument).The profile of various thermopair is often far from it because of needs, but their basic structure is roughly the same, is usually made up of major parts such as thermode, insulation sleeve protection tube and terminal boxes, and usual and Displaying Meter, recorder and electronic controller support the use.Traditional thermocouple ga (u)ge joint is assembling in the process of tightening, and the tinsel of the inside can be made to twist off, and produces knotting phenomenon, causes damage of product, brings loss to production.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of thermocouple ga (u)ge dual-thread seal joint that can prevent tinsel in thermocouple ga (u)ge joint assembling process from twisting off and tiing a knot.
The utility model in order to the technical scheme solving its technical matters and adopt is: a kind of thermocouple ga (u)ge dual-thread seal joint, comprise extruding external member and gland nut, be provided with in described gland nut and the inner chamber extruding external member and coordinate, the upper part of described extruding external member and inner chamber closely cooperates, the intracavity sidewall of described gland nut is provided with a groove, the lateral wall of described extruding external member is provided with and is fixed with a metal bar, described metal bar is embedded in groove, makes can not produce relative rotation between extruding external member and gland nut.
As further improvement of the utility model, described metal bar is cylindrical, and the diameter of metal bar is between 3.5-5mm.
As further improvement of the utility model, the length of described metal bar is lower than the length compressing external member.
The beneficial effects of the utility model are: thermocouple ga (u)ge dual-thread seal joint of the present utility model, a groove is provided with in gland nut, corresponding extruding external member is welded with a metal bar, in gland nut assembling rundown process, the compression external member of joint inside can not produce relative rotation, be used for preventing thermo-electric metal line through gland nut and and nut is tightened time External Force Acting that thermocouple wire is brought, tinsel is made to tie a knot or twist off, greatly reduce in assembling thermopair process, the loss that manual operation brings thermocouple wire, significantly reduce the production cost of enterprise.
