Specific embodiment
It should be noted that the feature in embodiment and embodiment in the case where not colliding, in the invention
It can be combined with each other.
Detailed description of specific embodiments of the invention is provided below.
A method of solenoid directional control valve commutating speed being improved, as shown in Figures 1 to 3, in connection solenoid valve commutating coil 1
In circuit, it is arranged in parallel high voltage supply control route and low-voltage power supply control route, low-voltage power supply voltage is line solenoid valve
Voltage rating is enclosed, high-voltage suppling power voltage is 2-3 times of electromagnetic valve coil voltage rating；
High voltage supply controls and is equipped with time relay KT normally opened contact in route, which routes high voltage power supply and supply
Electricity；Low-voltage power supply controls and is equipped with intermediate relay KM normally opened contact and isolating diode 2 in route, which controls route
It is powered by low-tension supply；In general, isolating diode 2 to be arranged in the normally opened contact and electromagnetism of intermediate relay KM by diagram direction
Between valve commutating coil；
After having control signal, the time relay and intermediate relay coil are powered simultaneously, and the electromagnetic force of coil generation is by the time
The normally opened contact of relay and intermediate relay is closed at, and due to the buffer action of isolating diode, makes high voltage power supply to electricity
Magnet valve coil power supply realizes that solenoid valve quickly commutates；
After the time relay reaches setting time, the normally opened contact of the time relay is disconnected, cutoff high power supply power supply, by low pressure
Power supply continues as electromagnetic valve coil power supply by isolating diode, keeps commutation states.
For the service performance of solenoid directional control valve, when the supply voltage of direct solenoid reversal valve is lower than the 20% of rated value,
Since the thrust deficiency that electromagnet generates fully open spool can not by valve port in place completely, the flow of valve port will be reduced
50% or more, simultaneously because thrust deficiency also extends the commutating period of solenoid valve.
The thrust that electromagnet generates is directly proportional to the number of turns of coil and by the electric current of coil, therefore improves supply voltage just
The electric current for flowing through coil can be improved, electromagnet thrust is provided, still, the understanding of those skilled in the art's conventional technique is to mention
High coil current can be such that coil heating even burns out, and not take into account that the technological means that can bring such serious adverse effect generally.
And the present invention exactly overcomes above-mentioned technology prejudice, exactly flows through coil electricity using supply voltage is improved to improve
The mode of stream, accelerates the commutating speed of valve, in technical solution provided by the invention, starts the moment of commutation in solenoid directional control valve
(in 1 second) high voltage supply, which generates higher electromagnet thrust, makes spool high acceleration commutate, and is kept after commutation using voltage rating
Commutation states, conduction time control in very short time range, avoid the drawbacks of coil current overheats coil, therefore,
Achieve breakthrough technical effect.
In general, the above-mentioned time relay uses the open type time relay.The power supply electricity of above-mentioned low-voltage power supply control route
Source uses the voltage rating of electromagnetic coil.The power supply of above-mentioned high voltage supply control route uses the electricity of 2-3 times of voltage rating
Source.
When controlling signal to electricity, the coil of intermediate relay KM and time relay KT of electromagnetic valve coil are controlled simultaneously
Must be electric, the opened point closure of time relay KT and the opened point of intermediate relay are closed at, and pass through the time relay of closure
The high-voltage power voltage of the opened point of device is greater than the voltage rating by intermediate relay KM, since the isolation of isolating diode is made
With, by giving solenoid directional control valve coil power supply by the high voltage power supply of the contact of the time relay, due to high voltage generate it is instantaneous
High current makes solenoid valve commutating coil generate the electromagnetic force bigger compared with voltage rating, thus adds block commutating period, improves and changes
To speed.
It should be noted that since time relay delay is not more than 1 second, in a certain range due to high voltage electricity
The fever of high current caused by source can be ignored.
After delay time arrives, the time relay opened point of actuation is disconnected, the touching for passing through intermediate relay by 24V power supply
Point, to the coil power supply of solenoid directional control valve, makes the coil of solenoid directional control valve keep commutation states through isolating diode, until control
Signal terminates power loss.
By being arranged in parallel, high voltage supply controls the time relay normally open contact of line powering to the present invention and low pressure supplies
The intermediate relay normally opened contact of electric control route is high to solenoid valve commutating coil power supply moment by high voltage supply control route
Pressure realizes solenoid valve commutation, and commutating speed is fast, avoids coil overheat.
