Direct-acting oxygen production valve

Abstract

The invention discloses a direct-acting oxygen generation valve, and belongs to the technical field of oxygen generation valves. The direct-acting oxygen generation valve comprises a confluence plate and valve groups; the confluence plate is provided with an air inlet channel, an air outlet channel, an exhaust channel and a connecting channel, the air inlet channel is connected with an external compressor, and the air outlet channel is connected with an external molecular sieve; and the number of the valve groups is at least one, the valve group comprises an air inlet valve and an exhaust valve, the air inlet valve and the exhaust valve are both connected with the confluence plate, the air inlet channel, the air inlet valve, the connecting channel, the exhaust valve and the exhaust channel are communicated in sequence, and the air outlet channel is communicated with the connecting channel. The whole oxygen generation valve can be started at zero air pressure, each valve group can independently regulate the pressure to achieve the purpose of staggered output, so that the adaptability of the whole oxygen generation valve is improved, the pressure of gas output into the molecular sieve can be kept constant through pressure adjusting, the gas pressure requirement of the oxygen generator is met, the good oxygen generation capacity of the oxygen generator is ensured, and the oxygen concentration is improved.

Description

technical field [0001] The invention belongs to the technical field of oxygen making valves, in particular to a direct-acting oxygen making valve. Background technique [0002] Oxygen is an indispensable substance to maintain human life. However, in some special cases, people have to face an environment lacking oxygen, or require a higher concentration of oxygen. Based on this demand, the application of oxygen generators was born. Among them, the oxygen generator valve is a device for extracting oxygen from the air. It uses physical adsorption technology and desorption technology to absorb nitrogen in the air, and the remaining unabsorbed oxygen is collected, and after purification treatment, high-purity clean oxygen is obtained. [0003] The current oxygen making valve, because after each use, there will be some gas inside, so that it can be started only after reaching the minimum starting pressure value for each subsequent use, which lacks convenience in use.

[0003] The current oxygen making valve, because after each use, there will be some gas inside, so that it can be started only after reaching the minimum starting pressure value for each subsequent use, which lacks convenience in use. At the same time, this The valve body of this kind of oxygen generator often only has the function of opening and closing, and cannot adjust the pressure during use to meet the pressure requirements of different oxygen generators.
