Description of drawings
Fig. 1 is the quick release circuit constitutional diagram of Redundant Control of the present invention;
Wherein reference character is: 1-resistance, 2-diode, 3-reference diode.
Embodiment
As shown in Figure 1, the quick release circuit of Redundant Control, comprise power supply and the first quick releasing unit, the first quick releasing unit comprises pure resistance, diode, discharges components and parts fast, the positive pole of one termination power of pure resistance, the negative pole of another terminating diode, the positive pole of diode connect quick release components and parts one end, discharge fast the negative pole of another termination power of components and parts, electromagnetic valve coil is connected to the two ends of power supply.
The combination that general quick release components and parts are electric capacity, resistance or resistance and electric capacity.
Perhaps discharging fast components and parts is reference diode, and the positive pole of diode connects the positive pole of reference diode, and the negative pole of reference diode connects power cathode.
For redundancy, operated by rotary motion has two quick releasing units, namely also comprises the second quick releasing unit in parallel and identical with the first quick releasing unit.
The effect of pure resistance is in the situation that diode and the quick components and parts that discharge lost efficacy, and is used for guaranteeing the normal power supply of electromagnetic valve coil.
During solenoid valve design of the present invention, for the response time is closed in raising, by in solenoid valve control circuit, increasing the quick release circuit of a kind of Redundant Control, reduced the solenoid valve design difficulty, greatly improve the closed electromagnetic valve speed of response, reduced to close the response time, satisfied designing requirement.
When power supply was switched on, releasing unit was because the adhesive of solenoid valve armature is powered in the diode cut-off to electromagnetic valve coil fast; When outage, the counterelectromotive force that electromagnetic valve coil produces acts on the quick release components and parts, discharges fast components and parts and punctures fast, realizes the quick release of counterelectromotive force, satisfies the time requirement that solenoid valve discharges fast.
Although foregoing description and accompanying drawing to the present embodiment have represented preferred version of the present invention, but those skilled in the art can carry out variously augmenting, improving and change in the situation that does not depart from the scope that claim defines according to different designing requirements and design parameter, therefore, the present invention is widely.
