Fig. 2 is the flow chart of device work in the utility model.
Embodiment
For clearly demonstrating the fuel cell inlet and outlet control device in the utility model, provide preferred embodiment below and be described with reference to the accompanying drawings.
Referring to Fig. 1, Fig. 1 is the structure chart of embodiment one, comprising: measure the transducer whether water level is higher than/is lower than predetermined water level and send corresponding signal, receive the single-chip microcomputer of described sensor signal, the drain solenoid valve that opens or closes under Single-chip Controlling.
Level sensor is connected with the pin of the signal input part of single-chip microcomputer, and water level sends triggering signal when being higher than predetermined water level or being lower than predetermined water level; The pin of the single-chip microcomputer signal output part drain solenoid valve that is connected, single-chip microcomputer judges that after receiving input signal if this input signal is the triggering signal that is higher than predetermined water level, then single-chip microcomputer sends the control of turning signal to drain solenoid valve, at this moment, drain solenoid valve is opened; If this input signal is the triggering signal that is lower than predetermined water level, then single-chip microcomputer sends the control signal of cutting out to drain solenoid valve, and at this moment, drain solenoid valve is closed.
Between drain solenoid valve and single-chip microcomputer, be connected with triode, single-chip microcomputer can be amplified to the control signal that drain solenoid valve sends, with the control drain solenoid valve.Wherein, the base stage of triode connects the pin of described single-chip microcomputer input signal, grounded emitter, and collector electrode connects described drain solenoid valve; Also be connected adjusting resistance at drain solenoid valve with single-chip microcomputer, to regulate voltage, the electric current of circuit.
This device can be installed in the knockout drum of fuel cell, with level sensor, when the electromagnetism draining valve is installed in knockout drum, level sensor is installed on the precalculated position according to the moisture storage capacity of knockout drum.The course of work such as Fig. 2, shown in after the operation of fuel cells, beginning is draining in knockout drum, after the water level in the knockout drum is higher than the precalculated position, level sensor sends triggering signal to single-chip microcomputer, the control signal of drain solenoid valve is opened in single-chip microcomputer output, open after the drain solenoid valve received signal, water in the knockout drum is discharged, decline of water table, when decline of water table behind the precalculated position, level sensor sends triggering signal to single-chip microcomputer, the control signal of drain solenoid valve is closed in single-chip microcomputer output, closes after the drain solenoid valve received signal, and knockout drum stops draining.
Water level in the knockout drum of this device may command fuel cell, during the dilutional hyponatremia that guarantees in detecting the fuel cell knockout drum, to build up, automatically too much water is emitted, to guarantee the operate as normal of fuel cell knockout drum, and the operate as normal of fuel cell and its peripheral other equipment, improve the coefficient of safety of fuel cell, avoided accident potential.
Describe the device among the embodiment above in detail; for the water-level control apparatus of setting forth among the embodiment; all within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
