Fig. 2 is the structural representation of the oxygen pressure charging system of this utility model medical oxygen backbone.
The specific embodiment
See also Fig. 2, the oxygen pressure charging system of the medical oxygen backbone shown in the figure is connected with oxygen processed center 401, the oxygen one tunnel that this oxygen processed center 401 is supplied with is delivered to through the pipe network of supplying gas uses the oxygen terminal, and for each section office's use of hospital, another road is delivered to this oxygen pressure charging system.
This oxygen pressure charging system comprises: supercharger 301 and air accumulator 302.
This supercharger 301 is connected with oxygen processed center 401, and its connecting line 601 is provided with valve 1, valve 2 102.
This air accumulator 302 is connected with this supercharger 301, to this air accumulator 302, is provided with check valve 1 and valve 3 103 from this supercharger 301 on its connecting line 602 successively.
This air accumulator 302 also is connected with Hyperbaric oxygen chamber system 501 by connecting line 603, to this Hyperbaric oxygen chamber system 501, is provided with valve 4 104 and air relief valve 1, air relief valve 2 106 from this air accumulator 302 on this connecting line 603 successively; The pressure set points of this air relief valve 1 is 4.0kg/cm
2, the pressure set points of this air relief valve 2 106 is 2.0kg/cm
2
The first air feed bypass 604, the second air feed bypass 605;
The inlet end of this first air feed bypass 604 is arranged on the connecting line 601, and between valve 1, valve 2 102; The outlet side is arranged on the connecting line 603, and between air relief valve 1, air relief valve 2 106; To this outlet side, successively be provided with valve five 107, check valve three 203, valve six 108 in this first air feed bypass 604 from this inlet end.
The inlet end of this second air feed bypass 605 is arranged in the first air feed bypass 604, and between check valve 3 203, valve 6 108; The outlet side is arranged on the connecting line 602, and between valve 3 103 and air accumulator 302, to this outlet side, successively is provided with valve seven 109, check valve two 202 in this second air feed bypass 605 from this inlet end.
More excellent, above-mentioned supercharger 301 does not have oily supercharger for single-stage.
During this oxygen pressure charging system work, at first Open valve 1, valve 2 102, valve 3 103, valve 5 107, valve 6 108, valve 7 109, the oxygen that oxygen processed center 401 is supplied with is along the first air feed bypass 604, through valve 5 107, check valve 3 203, then, one tunnel valve 7 109, check valve 2 202 in the second air feed bypass 605 is delivered to connecting line 602, enters air accumulator 302 then; Another road is delivered to connecting line 603 behind the valve 6 108 in the first air feed bypass 604, by air relief valve 2 106 oxygen pneumatic is decompressed to 2.0kg/cm again
2Use for Hyperbaric oxygen chamber system 501 back.After oxygen pneumatic and the air pressure balance in the air accumulator 302 that oxygen processed center 401 is supplied with, supercharger 301 starts, and continues to air accumulator 302 interior delivering oxygens, and the force value in air accumulator 302 reaches 8.0kg/cm
