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 low-temperature liquid experiments, in particular to a visual test device for low-temperature liquefied gas. Background technique [0002] Industrial gas is the "blood" of modern industry, and its application covers many important fields such as iron and steel, metallurgy, chemical industry, shipbuilding, automobile, medicine, food, electronics, petroleum, aerospace and so on. With the rapid economic development, the demand for industrial gases is also surging. Liquid nitrogen and liquid oxygen are two cryogenic liquids commonly used in industrial production. With the wide application of clean energy, the application of these two cryogenic liquids in the national economy is becoming more and more extensive. [0003] Existing containers for cryogenic liquids such as liquid nitrogen, liquid oxygen, and liquid hydrogen are mostly used for storage and transportation, and experimental devices for experimental...
