Problems solved by technology

[0003] At present, when installing low-temperature temperature sensors, according to the shape of the sensor and other conditions, the sensor is usually pasted on the low-temperature container with low-temperature glue. This installation method is limited by the performance of the low-temperature glue, and the fixation is not firm, and it is inconvenient to replace.

Embodiment 1

[0035] Embodiment 1: A kind of installation structure of cryogenic temperature sensor, such as figure 1 As shown, it includes a T-shaped hollow screw 1 and a fixing nut 2 threadedly engaged with the hollow screw 1. The fixing nut 2 is hollow and includes a threaded section, an accommodating section and an extending section in turn, and the threaded section cooperates with the hollow screw 1. The hollow screw 1 is slidably connected with a connecting pipe 3, the middle part of the connecting pipe 3 has an axial temperature measurement perforation, the end of the connecting pipe 3 has a connecting sleeve edge 4 which conflicts with the hollow screw 1, and the end of the connecting pipe 3 far away from the connecting sleeve edge 4 is used to communicate with the Welding of the side wall of the cryogenic vessel. The temperature measuring perforation is pierced with a temperature sleeve 5 made of copper, and the temperature sleeve 5 is provided with an accommodating groove 6 along ...

Embodiment 2

[0040] Embodiment 2: A kind of installation structure of cryogenic temperature sensor, such as figure 2 and image 3 Shown, the difference of present embodiment 2 and embodiment 1 is:

[0041] The inner surface of the hollow screw 1 is provided with a limiting groove 13, and the outer surface of the connecting pipe 3 is provided with a limiting convex strip 14. The limiting convex strip 14 is the same size as the limiting groove 13. The limiting protrusions 14 are separated from the limiting grooves 13 with a distance of 1-2 mm.

[0042] The side of the temperature sleeve 5 is provided with a first outlet 11, and the fixing nut 2 is provided with a second outlet 12. The side of the first outlet 11 away from the accommodation tank 6 is arc-shaped and inclined to the direction away from the bottom of the accommodation tank 6. A guide groove 16 extending from the opening direction to the first outlet 11 is provided on the side of the accommodating groove 6 . One end of the ac...

Abstract

The invention discloses an installation structure of a low temperature sensor, which comprises a paired hollow screw and a fixing nut. The fixing nut is hollow and includes a threaded section, an accommodating section and an extension section whose size is smaller than the accommodating section. The hollow screw is internally connected There is a connecting pipe, the connecting pipe includes a temperature measuring perforation and a connecting sleeve edge in contact with the end of the hollow screw, the temperature measuring perforation is connected to a temperature sleeve, and a storage tank is opened in the temperature sleeve, and a low temperature sensor is placed at the bottom of the storage tank. The middle part of the outer wall of the temperature sleeve is provided with a mounting boss, and the diameter of the mounting boss is larger than the extension section. The temperature sleeve includes a connector protruding from the extension section. The connector is threaded with an adjustment nut, and the adjustment nut is connected with a top. The rod and the ejector rod are used to fix the low temperature sensor on the bottom of the accommodating tank. Through the above arrangement, it is convenient to install and replace the low temperature sensor, and the processing difficulty of the low temperature container is reduced. The invention also discloses a method for installing the low temperature sensor.

Description

technical field [0001] The invention relates to the technical field of installation of a low-temperature temperature sensor, in particular to an installation structure and an installation method of a low-temperature temperature sensor. Background technique [0002] Low temperature belongs to extreme technology and is a special field. The development of low temperature temperature sensor represents the current high-tech level to a certain extent. With the continuous expansion of the application of low temperature in military, aviation, aerospace, nuclear, energy, automation, medicine, biology, industrial and agricultural technologies, in various applications, it is necessary to determine the low temperature situation in time through low temperature temperature sensors. [0003] At present, when installing low-temperature temperature sensors, according to the shape of the sensor and other conditions, the sensor is usually pasted on the low-temperature container with low-temper...
