When measuring oxygenerator oxygen tank, bus-bar, the pressure value respectively less than 0.4MPa of output oxygen supply path, pressure switch sends alarm signal
Number to alarm, alarm is sent sound and light alarm signal, remind user to detect oxygen generating plant in time or change bus-bar or oxygen
Gas tank.
When having a power failure, oxygen making set system cannot normal work, now magnetic valve dead electricity, the first angle pedestal valve 2.3 disconnects, second
Angle pedestal valve 3.3 is open-minded, automatically switches to bus-bar oxygen supply.
When oxygen making set system breaks down, or oxygen consuming amount it is excessive and when causing oxygen-supplying amount not enough, be switched to bus-bar
Oxygen supply.
First auxiliary channel C1 and the second auxiliary channel C2, in the state of oxygenerator oxygen supply or bus-bar oxygen supply, it
Two ball valves 4 and the 4th ball valve 5 are in normally off, i.e., under oxygen supply state, the first auxiliary channel C1 and the second auxiliary channel
C2 is closed.The effect of its first auxiliary channel C1 and the second auxiliary channel C2：On the one hand ensure that structure of the present invention
Stability, on the other hand facilitate system overhaul.
The second ball valve 3.4 on the first ball valve 2.4 and the second oxygen path B on first oxygen path A, is in normally opened
State, it is ensured that under power down mode, the first angle pedestal valve 2.3 and the second angle pedestal valve 3.3 cannot be worked, it is impossible to which realization is cut automatically
Change, but the second oxygen path is in opening state, and bus-bar can continue to complete oxygen supply.
Two parts of each path of the present invention can be directly connected to or be connected by welding loose joint when being connected, and two logical
Road can be directly connected to or be connected by welding loose joint when being connected.Weld the effect of loose joint：On the one hand it is easy for zero
The installation and maintenance of part, on the other hand can be by adjustment welding loose joint, it is ensured that the opening handle of ball valve is just faced outwardly, it is to avoid
There is ball valve handle in box inside so that ball valve is awkward.
The present invention is due to there is two oxygen sources of oxygen supply of oxygenerator and bus-bar, and oxygenerator and bus-bar are during oxygen supply
Be capable of achieving to automatically switch, when oxygen making set system breaks down or has a power failure or oxygen consuming amount is excessive and oxygen-supplying amount is not enough, can directly from
Oxygenerator oxygen supply automatically switches to bus-bar oxygen supply, it is ensured that oxygen supply continues, so as to realize continuously oxygen supply.
