Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
Embodiment 1
As shown in Figure 1, a kind of Low Pressure Oxygen storehouse, comprise the oxygen storehouse for low pressure test (LPT), described oxygen storehouse is a lucite case, this oxygen storehouse is provided with oxygen air inlet and nitrogen air inlet, described oxygen air inlet is communicated with source of oxygen by oxygen flow meter and oxygen valve, described nitrogen air inlet is communicated with source nitrogen by nitrogen flow meter and nitrogen valve, the oxygen measurement device being connected with control oxygen instrument communicates with oxygen storehouse, for measuring the concentration of oxygen in oxygen storehouse, described oxygen valve and nitrogen valve are electrically connected with the control end of described control oxygen instrument respectively, regulate in real time described control oxygen instrument flow-control knob by observing the flow of described nitrogen flow meter and described oxygen flow meter, and then control oxygen valve and nitrogen valve, described oxygen storehouse is also provided with the exhaust outlet for discharging test gas.
Described oxygen is also provided with fan in storehouse, for gas in oxygen storehouse is mixed.
Described oxygen measurement device is oxygen sensor, is used for measuring oxygen concentration in described oxygen storehouse, and is transferred to described control oxygen instrument.
Described oxygen is provided with drying device in storehouse, and some animals and plants tests can make the humidity in oxygen storehouse increase, and analysis and the result of impact test, install the environment that drying device keeps constant humidity.
The use procedure in Low Pressure Oxygen storehouse
Embodiment 2 oxygen pressures are 10% low pressure test (LPT)
Oxygen pressure is 10% low pressure test (LPT), first oxygen sensor is calibrated, two passages of oxygen sensor are exposed in air, the display screen numeral of this time control oxygen instrument is slowly stabilized in 21% left and right, at this moment the calibration knob on regulation meter, digital regulated to 21% showing, stablize after 5-10 minute, then oxygen sensor is packed in oxygen storehouse;
Low pressure on control oxygen instrument is arranged to digital driver plate and be set to 13%, 10% higher by 3% than original, 3% of this raising is prepared for overshoot nitrogen, now, nitrogen valve is automatically opened and is started to inflated with nitrogen in oxygen storehouse, at this moment show that from control oxygen instrument numeral can see that numeral beating to low pressure, although what set on driver plate is 13%, but because the nitrogen being just charged in oxygen storehouse and the original mixed gas of air have individual lag time to diffusion in oxygen sensor, in the time showing that numeral stops declining to slowly ging up, progressively numeral is pushed to 12%-11%-10%, stablize about 20 minutes, can start test.
Embodiment 3 batch runs
In the time of experiment, to set Low Pressure Oxygen content by former provisioning request.As the oxygen of needs 10%, that is just first set to 10% from control oxygen instrument, and because of start oxygen drops from air, oxygen table relay is open-minded, and nitrogen valve is open-minded, nitrogen flow meter selection nitrogen flow, and nitrogen enters in oxygen storehouse, and it is 10% close that oxygen presses to.In the time that oxygen is pressed onto 10%, the tripping of oxygen table relay, nitrogen valve is closed, while jumping to 2 minutes Deng time-delay relay, this is the turnaround time that is returned to air 21% from 10%, and right wing relay is open-minded, and the upper limit relay of oxygen table is open-minded, the oxygen valve on the right is opened, oxygen flow meter is selected oxygen flow, and oxygen enters in oxygen storehouse, and oxygen presses liter, close to 21%, in the time that oxygen is pressed onto the upper limit 21%, oxygen table upper limit relay tripping oxygen valve is closed, when time-delay relay jumps to 2 minutes by the time, go round and begin again, reach batch run effect with this.Described in the present embodiment, oxygen table relay, time-delay relay, right wing relay and upper limit relay are all arranged in described control oxygen instrument.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
