Accompanying drawing explanation
Fig. 1 is coal mine escape capsule demand system schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model coal mine escape capsule demand system is described further.
In Fig. 1,1-battery, 2-power line, 3-pressure meter, 4-oxygen supply pipeline, 5-bottle valve, 6-oxygen cylinder group, 7-pressure reducer, 8-oxygen concentration monitor, 9-PLC, 10-control line, 11-electromagnetic valve, 12-oxygen supply valve, 13-electronic pressure gage.
Coal mine escape capsule demand system is connected to control system PLC 9 by battery 1 by power line 2, thus gives system power supply.Oxygen cylinder group 6 in oxygen system has a gauge tap bottle valve 5, and oxygen cylinder group 6 is connected to pressure meter 3, pressure reducer 7, electronic pressure gage 13, electromagnetic valve 11 and oxygen supply valve 12 successively, is all to connect by oxygen supply pipeline 4 between them.Pressure meter 3 can detect oxygen cylinder group 6 internal gas pressure.Pressure reducer 7 can reduce to low-pressure gas the gas of the elevated pressures be stored in gas cylinder, and should ensure that required operating pressure keeps stable state from start to finish.Electronic pressure gage 13 can detect through the post-decompression air pressure of pressure reducer 7.Electromagnetic valve 11 is controlled by PLC9, also plays on-off action.When oxygen supply valve 12 is opened, system just can outwards oxygen supply.Oxygen concentration detecting instrument 8 can detect extraneous oxygen concentration.PLC9, as control system, can receive the open and close of Controlling solenoid valve 11 while of the signal of oxygen concentration detecting instrument 8 transmission.
Battery 1 is connected with the PLC9 in system by power line 2.Bottle valve 5 is above oxygen cylinder group 6.Oxygen cylinder group 6 is connected to pressure meter 3, pressure reducer 7, electronic pressure gage 13, electromagnetic valve 11 and oxygen supply valve 12 successively, is all to connect by oxygen supply pipeline 4 between them.Wherein, pressure meter 3 one end is connected with the bottle valve 5 above oxygen cylinder group 6, and one end is connected with pressure reducer 7.Pressure reducer 7 other end is connected with electronic pressure gage 13.Electromagnetic valve 11 is connected to electronic pressure gage 13 and oxygen supply valve 12, is also connected to PLC9 by control line 10, and PLC9, as control system, is connected to oxygen concentration detecting instrument 8 and electromagnetic valve 11.
When oxygen system starts, first manual unlocking bottle valve 5 and oxygen supply valve 12, pressure meter 3 can show the oxygen pressure in oxygen cylinder group 6.Oxygen concentration detecting instrument 8 can monitor the oxygen concentration in survival capsule, and oxygen concentration data are sent to PLC9 process, when the oxygen concentration in cabin is lower than certain value, PLC9 can Controlling solenoid valve 11 open, the oxygen in oxygen cylinder group 6 through pressure reducer 7 by pressure reduce and be discharged in survival capsule by oxygen supply valve 12; After oxygen concentration exceedes normal value, oxygen concentration data can be sent in PLC9 by oxygen concentration detecting instrument 8, and PLC9 can close by Controlling solenoid valve 11, oxygen feeding stop.Whole system is powered by battery 1.
