Embodiment 1

[0033] Reference Figure 1-5 , Preferred embodiment 1 of the present invention provides a visual test device for low-temperature liquefied gas, which includes a rectangular parallelepiped tank body 1 with an upper opening and a cover plate 2. The tank body 1 includes an inner tank body 3 and an outer tank body 4 , The inner tank body 3 and the outer tank body 4 are provided with an insulating layer between the four sides of the inner tank body 3 and the top ends of the four sides of the inner tank body 3 are bent 90 degrees outward to form the tank top surface 5, and the cover plate 2 is a transparent cover plate and sealed Installed on the top surface 5 of the tank body to form a top observation window; the front and rear sides of the inner tank body 3, the thermal insulation layer, and the outer tank body 4 are provided with a number of mounting holes 6, and the front and rear sides of the tank body 1 pass through the mounting holes 6 A side observation window 7 is installed. ...

Embodiment 2

[0044] Reference Image 6 The preferred embodiment 2 of the present invention provides a visual test device for low-temperature liquefied gas. The only difference from embodiment 1 is that the structure of the side observation window 7 is different. The side observation window of this embodiment will be the same as the outer flange The connected transparent glass window is set as a concave transparent window 23, and the concave bottom surface is the visible surface parallel to the inner transparent glass window as close as possible to the transparent glass window on the inner flange, and the concave transparent window 23 is fixed. The end cover is provided with a see-through plate 22. The see-through plate 22 and the recessed see-through window 23 form an internal sealed space, which can be evacuated or filled with inert gas. A miniature camera 24 is provided in the internal sealed space, which passes through the sealing tube 25. The connection line is connected to an external m...

Embodiment 3

[0047] Reference Figure 7-8 The preferred embodiment 3 of the present invention provides a visual test device for low-temperature liquefied gas. The only difference from embodiment 1 is that one or two side observation windows are replaced with the side heating windows of the embodiment, that is, In the side heating window, the transparent glass window connected with the outer flange is set as a concave transparent window 23, and the transparent glass window connected with the inner flange is replaced with a heater. The heater includes a closed end face on the right side. A heat-conducting cylinder 26. A number of heat-conducting fins 28 are evenly provided on the circumferential side of the heat-conducting cylinder 26. A heat-collecting fin 27 is arranged inside the heat-conducting cylinder 26. The connecting wire in the connecting pipe 30 is connected to an external heating controller.

[0048] This embodiment uses a unique heat conduction heating method to heat the internal ...

Abstract

A visual test device used for low-temperature liquified gas is provided. The visual test device includes an inner tank body, an insulating layer, an outer tank body and a cover plate. Tops of four side surfaces of the inner tank body are bent outwards by 90 degrees to form a tank body top surface. The cover plate is a transparent cover plate and is mounted in a sealed manner at the tank body top surface to form a top observation window. Front and back side surfaces of the inner tank body, the insulating layer and the outer tank body are provided with a plurality of mounting holes. The front and back side surfaces of the tank bodies are mounted with side observation windows through the mounting holes. The two sides of the test device are provided with the eight observation windows so that situations in the test device can be observed dynamically, and the large observation window is designed at the top, and therefore the inside of the test device is visual in a three-dimensional manner and the visual range is greatly increased.

Description

Technical field [0001] The invention relates to the technical field of cryogenic liquid experiments, in particular to a visual test device for cryogenic liquefied gas. Background technique [0002] Industrial gas is the "blood" of modern industry, and its applications are in many important fields such as steel, metallurgy, chemical industry, shipbuilding, automobiles, medicine, food, electronics, petroleum, aerospace and so on. With the rapid economic development, the demand for industrial gases is also increasing sharply. Liquid nitrogen and liquid oxygen are two commonly used cryogenic liquids in industrial production. With the widespread application of clean energy, the application of these two cryogenic liquids in the national economy has become more and more extensive. [0003] The existing containers for cryogenic liquids such as liquid nitrogen, liquid oxygen and liquid hydrogen are mostly used for storage and transportation. Experimental devices used for experimental resea...
