Abstract

The invention discloses a stable oxygen supply device, which comprises an intermediate tank, a first linkage pressure stabilizing component and a second linkage pressure stabilizing component, wherein the first linkage pressure stabilizing component is connected between the intermediate tank and an oxygen using unit and passively controls the self air inlet rate according to the pressure of the oxygen using unit; the second linkage pressure stabilizing assembly is connected between the intermediate tank and the oxygen storage unit and passively controls the air inlet rate of the second linkage pressure stabilizing assembly according to the pressure of the intermediate tank. The stable oxygen supply device provided by the invention realizes the gradual and orderly reduction of the pressure and effectively alleviates the pressure fluctuation through the two-stage linkage of the first linkage pressure stabilizing assembly and the second linkage pressure stabilizing assembly.

Description

Stable oxygen supply device
Technical Field
The invention relates to a chemical raw material technology, in particular to a stable oxygen supply device.
Background
As is known, oxygen is widely used in the fields of industry, commerce, medical treatment and the like, in the prior art, an oxygen storage mechanism is an oxygen cylinder (tank) with a national standard, which is used as a high-pressure storage device, and the oxygen cylinder is a standard component with a corresponding national standard and generally comprises a bottle body, a bottle hoop, a bottle cap and a bottle valve, and as disclosed in the patent application with the application publication number CN103381279A, the invention discloses such an oxygen cylinder.
Obviously, due to the difference of practical requirements, for example, welding oxygen requires high-speed high-concentration oxygen, medical oxygen requires low-speed oxygen with proper temperature, and since the oxygen cylinder of the standard part can only be used for adjusting the flow rate, corresponding intermediate adjusting devices have to be configured to meet the corresponding requirements, such as those provided in the patent applications with application publication numbers CN103908716A, CN103090130A and CN 107754067A.
The prior art has the disadvantages that the output pressure of the oxygen cylinder is generally adjusted by hand slightly, the actually required pressure is less than the output pressure of the oxygen cylinder with great probability, the difference between the two pressures causes the actually used oxygen pressure to fluctuate, and the prior art lacks a technical means for slowing or even eliminating the fluctuation.
Disclosure of Invention
The invention aims to provide a stable oxygen supply device to solve the defects in the technology.
In order to achieve the above purpose, the invention provides the following technical scheme:
a stabilized oxygen supply comprising:
an intermediate tank;
the first linkage pressure stabilizing component is connected between the intermediate tank and the oxygen utilization unit and passively controls the air inlet rate of the first linkage pressure stabilizing component according to the pressure of the oxygen utilization unit;
and the second linkage pressure stabilizing assembly is connected between the intermediate tank and the oxygen storage unit and passively controls the air inlet rate of the second linkage pressure stabilizing assembly according to the pressure of the intermediate tank.
The above oxygen supply device further includes:
the oxygen storage unit is an oxygen cylinder, the auxiliary support is supported at the bottleneck of the oxygen cylinder through a connecting structure at the end part of the auxiliary support, and the intermediate tank, the first linkage pressure stabilizing component and the second linkage pressure stabilizing component are uniformly distributed on the auxiliary support.
The oxygen supply device further comprises a box body, wherein the intermediate tank, the first linkage pressure stabilizing assembly and the second linkage pressure stabilizing assembly are integrated in the box body, and the box body is fixed on the auxiliary support.
In the oxygen supply device, the first linkage pressure stabilizing assembly and the second linkage pressure stabilizing assembly are both mechanical passive triggering structures.
