Description
Technical field
The utility model relates to temperature measuring device technical field, and what be specifically related to is a kind of couple sealing.
Background technique
Thermocouple is temperature measuring element conventional in temperature measuring instrument, its direct measuring tempeature, and temperature signal is converted to thermal electromotive force signal, is converted to the temperature of measured medium by electric meter.The profile of various thermocouple is often not identical because of needs, but their basic structure is roughly the same, is usually made up of major components such as thermode, insulating bush protective tube and terminal boxes, and usual and Displaying Meter, record instrumentation and electronic controller support the use.
Thermocouple lead must be drawn from container inner wall when carrying out inner wall temperature and measuring by high-pressure bottle, must be provided with lead-in wire fairlead at container wall, for ensureing the high pressure sealing at container fairlead place, and installs special thermocouple lead sealing equipment.
Model utility content
For the deficiency that prior art exists, the utility model provides a kind of couple sealing of good seal performance.
To achieve these goals, the utility model realizes by the following technical solutions:
A kind of couple sealing, it is characterized in that it comprises joint, nut, sealing surface head and sealed compartment, described joint is hollow structure, joint one end outer surface arranges the outside thread being used for being connected with container, described joint the other end outer surface arranges the outside thread being used for being connected with nut, the end of the described joint the other end arranges arc-shaped concave, the arc-shaped concave of described end is arranged a circle groove, arranges the first sealant layer in described groove; Described sealing surface head is also hollow structure, and the first end of described sealing surface arranges the arc convex coordinated with described arc-shaped concave; Run through a thermocouple probe in the hollow structure of described joint with in the hollow structure of sealing surface head, the two the first sealant layers are set between the thermocouple probe of a part and the inwall of sealing surface head in the hollow structure of sealing surface head; The first end of described sealing surface arranges a circle raised step, arrange in described nut and described one enclose that raised step coordinates one enclose cavity, by described nut, the arc convex of the arc-shaped concave of described joint and sealing surface head is closely cooperated; Described sealed compartment at least one, described sealed compartment arranges in the hollow structure of joint, and described sealed compartment is arranged and is used for the hole passed of thermocouple probe, the edge of described sealed compartment arranges the 3rd sealant layer.
According to an embodiment of the present utility model, described sealed compartment is 3.
