Technical Field

[0001] The utility model relates to the technical field of gas mixing, in particular to an automatic multi-type gas proportioning device. Background Art

[0002] In industry, products that are gaseous at room temperature and pressure are collectively referred to as industrial gas products. There are many types of gas products, which can be roughly divided into two categories: general industrial gases and special gases. The production and sales volume of general industrial gases is large, but the purity requirements are not high. Although the production and sales volume of special gases is small, according to different uses, there are extremely strict requirements for the purity or composition of different special gases, the maximum content of harmful impurities allowed, and the packaging, storage and transportation of products. They are high-tech and high value-added products. Usually, special gases can be divided into three categories, namely high-purity or ultra-high-purity gases, standard calibration gases, and mixed gases with specific compositions. As an important basic raw material for modern industry, gas products have a wide range of applications. In metallurgy, steel, petroleum, chemical industry, machinery, electronics, glass, ceramics, building materials, construction, food processing, medicine and medical care, etc., a large amount of common gases or special gases are used.
