Detailed Description

The invention will be further described with reference to the following drawings and examples:

example (b): temperature calibration instrument

Referring to fig. 1, the measuring tube body 1 includes a first segment, a second segment and a third segment, wherein the first segment, the second segment and the third segment are sequentially connected to each other along a length direction of the measuring tube body 1, and the first segment is defined as an upper segment, the second segment is defined as a middle segment and the third segment is defined as a lower segment.

The upper segment is a calibration segment 10, a plurality of temperature marked lines are sequentially carved on the calibration segment 10 along the length direction of the measuring pipe body 1, and temperature values on all the temperature marked lines are sequentially increased from the middle segment to the upper segment.

The inner wall of the calibration section 10 is sequentially provided with a plurality of non-return teeth 4, the non-return teeth 4 are sequentially and uniformly arranged at intervals along the length direction of the measuring pipe body 1, and all the non-return teeth 4 are inclined towards the direction from the middle section to the upper section so as to prevent the movable plug 3 from falling back. In this embodiment, the movable plug 3 is a fluorosilicone rubber plug.

The middle section is a piston motion section 11, a movable plug 3 capable of floating upwards is arranged in the piston motion section 11, the lower section is an expansion section 12, an air bag 2 capable of expanding along with temperature rise is arranged in the expansion section 12, the air bag 2 can extrude the movable plug 3 from the middle section to the upper section (upwards in the figure) in the expansion state, so that the movable plug 3 floats upwards, and the scale indicated by the position where the movable plug 3 is located and the scale line coincides represents the temperature value of the current environment.
