Specific embodiment
With reference to the accompanying drawing and the present invention is described further in specific embodiment.
Embodiment 1
It is as shown in Figure 1 the schematic diagram of the pulse control unit of DC electromagnetic valve of the present invention, as seen from the figure, which includes
DC power supply, further include magnetic latching relay for receiving unbalanced pulse signal and for generating reseting pulse signal so that
The reset pulse generation circuit that magnetic latching relay resets, DC electromagnetic valve and magnetic latching relay are for being serially connected in DC power supply
In power supply circuit between positive and negative anodes；When DC power supply is connected, magnetic latching relay is used for the control in unbalanced pulse signal
Under open DC electromagnetic valve；When electrifying DC power supply, reset that magnetic latching relay is sent in reset pulse generation circuit
It realizes and resets under the control of pulse signal.
Magnetic latching relay has been developed in recent years a kind of new type of relay and a kind of automatic switch.And other
Electromagnetic relay is the same, plays turn on automatically and cutting action to circuit.The difference is that magnetic latching relay is normally closed or normal
Open state be entirely rely on permanent-magnet steel effect, the conversion of switch state be by one fixed width pulse electrical signal triggering and
It completes.The contact switching current maximum of magnetic latching relay is up to 150A；Control coil voltage is divided into DC9V, DC12V etc..One
As appliance life 10000 times；Mechanical life 1000000 times；Contact contact drop < 100mV.Therefore, have power saving, performance steady
Fixed, small in size, large carrying capacity, the characteristics of than general electromagnetic relay superior performance.
The operating principle of magnetic latching relay are as follows: its contact opening and closing state of magnetic latching relay is usually by permanent magnet institute
The magnetic force of generation is kept.When the contact of relay needs to open or when conjunction state, it is only necessary to sharp with positive (anti-) DC pulse voltage
Coil is encouraged, relay is just completed out in moment and converted with the state closed.Normally when the contact is in the holding state, coil does not need
Continue to be powered, only the state of relay can be maintained constant by the magnetic force of permanent magnet.
There are many ways of realization for reset pulse generation circuit, as long as can satisfy above-mentioned function.
Embodiment 2
As shown in Fig. 2, both ends B1, B2 and unbalanced pulse signal of the pull-in winding J1 of magnetic latching relay are connected, direct current
Positive pole is connect with one end of direct solenoid valve coil, the main contacts A connection of the other end and magnetic latching relay, normally opened touching
The connection of the cathode of point A2 and DC power supply, normally-closed contact A1 sky connect；In addition, the positive and negative anodes of DC power supply respectively with time-delay relay
Two-end-point c1, c2 of coil TD is connected to, the master that two-end-point D2, D1 of magnetic latching relay resetting coil J2 passes through time-delay relay
Contact b and normally opened contact b1 are connected to the positive and negative anodes of DC power supply, and corresponding normally-closed contact b2 sky connects.
Working principle of the present invention is as follows: unbalanced pulse signal is by controlling the pull-in winding J1 of magnetic latching relay come real
The unlatching of existing DC electromagnetic valve, DC power supply realize that magnetic keeps relay by the reseting pulse signal of reset pulse generation circuit
The movement of device resetting coil.
As shown in figure 3, making the actuation of magnetic latching relay by the connection of terminal B 1, B2 after unbalanced pulse signal issues
Coil J1 obtains electric, and magnetic latching relay normally opened contact A2 is closed and is always maintained at closed state, while DC power supply is added in direct current
On the coil of solenoid valve, DC electromagnetic valve is opened.At the end of direct solenoid valve opening time, DC power supply is directly closed, this
When DC electromagnetic valve coil losing electricity, DC electromagnetic valve closure.
When electrifying DC power supply, time-delay relay timing starts, while the coil TD of time-delay relay obtains electric, normally opened touching
Point b1 closure, DC power supply are loaded directly on the resetting coil J2 of magnetic latching relay, the resetting coil of magnetic latching relay
It obtains electric.At the end of time-delay relay timing time reaches specified value, action sequence as shown in figure 3, time-delay relay coil
TD movement, normally opened contact b1 are disconnected, and normally opened contact b2 connection, time-delay relay is transformed into off state and always by on-state
It is held off, until input voltage removes, the DC power supply being loaded on magnetic latching relay at this time is disconnected, then magnetic is kept
The resetting coil J2 power loss of relay, is consequently formed the reseting pulse signal of a magnetic latching relay, makes magnetic latching relay
It returns to original state.
The above embodiments are only used to help understand the core ideas of the present invention, and the present invention cannot be limited in this way, for ability
The technical staff in domain, it is all to modify or equivalently replace the present invention according to the thought of the present invention, in specific embodiment
And any change done in application range, it should all be included in the protection scope of the present invention.
