Small high-concentration liquid oxygen quantitative distribution device

Abstract

The invention discloses a small high-concentration liquid oxygen quantitative distribution device. The small high-concentration liquid oxygen quantitative distribution device comprises a machine body.The machine body is internally provided with an oxygen storage cavity for storing high-concentration liquid oxygen. The machine body is internally provided with a connecting cavity, a switch body isrotatably arranged in the connecting cavity, three sets of replacement grooves are evenly formed in the switch body, and liquid oxygen tanks for storing high-concentration liquid oxygen are placed inthe replacement grooves. The small high-concentration liquid oxygen quantitative distribution device is simple in structure and convenient to operate and maintain, automatic filling in a closed cavityis realized to effectively avoid the leakage of liquid oxygen caused by the unreliable filling connection, the working environment of the staff is improved, the probability of high-concentration oxygen contacting the staff is reduced, the staff are prevented from oxygen poisoning incidents, automatic oxygen filling greatly improves the efficiency of oxygen filling, consistent filling volume is ensured, product quality is greatly improved, and therefore, the small high-concentration liquid oxygen quantitative distribution device has high use and promotion value.

Description

technical field [0001] The invention relates to the field of gas storage, in particular to a small-sized high-concentration liquid oxygen quantitative distribution device. Background technique [0002] Liquid oxygen has a wide range of industrial and medical uses, but due to its physical and chemical properties, organic matter is prone to violent combustion in liquid oxygen, so in small high-concentration liquid oxygen distribution stations, liquid oxygen filling is mostly done manually Filling, the work intensity is high, the efficiency is low, and the staff directly contact the filling equipment, there is a certain risk of life safety, and the risk of liquid oxygen leakage during the filling process is high, and the staff is prone to oxygen poisoning, so , the present invention aims to design a small-scale high-concentration liquid oxygen quantitative distribution device. Contents of the invention [0003] The object of the present invention is to provide a small-sized ...
