Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the present invention is described further.
Embodiment 1
Be illustrated in figure 1 the schematic diagram of the pulse control unit of DC electromagnetic valve of the present invention, as seen from the figure, this device comprises DC electrical source, also comprise the magnetic latching relay for receiving unbalanced pulse signal and produce circuit for generation of reseting pulse signal with the reset pulse making magnetic latching relay reset, DC electromagnetic valve and magnetic latching relay are for being serially connected in the power supply circuits between DC electrical source both positive and negative polarity; When DC electrical source is connected, magnetic latching relay is used under the control of unbalanced pulse signal, make DC electromagnetic valve open; When electrifying DC power supply, magnetic latching relay realizes resetting under reset pulse produces the control of the reseting pulse signal that circuit sends.
Magnetic latching relay is a kind of new type of relay grown up in recent years, is also a kind of recloser.The same with other electromagnetic relays, circuit is played and automatically connects and cutting action.Difference is, the normally closed or normally open of magnetic latching relay is the effect relying on permanent-magnet steel completely, and the conversion of its on off state leans on the pulse electrical signal of one fixed width to trigger.The contact switching current of magnetic latching relay is maximum reaches 150A; Control coil voltage is divided into DC9V, DC12V etc.General appliance life 10000 times; Mechanical life 1000000 times; Contact pressure drop <100mV.Therefore, there is power saving, stable performance, volume is little, bearing capacity is large, than the feature of general electromagnetic relay superior performance.
The operating principle of magnetic latching relay by: the magnetic force that its contact opening and closing state of magnetic latching relay is produced by permanent magnet is at ordinary times kept.When the contact of relay needs open or close state, only need to use just (instead) DC pulse voltage drive coil, relay just completed out and the State Transferring closed in moment.When usual contact is in hold mode, coil does not need to continue energising, only just can maintain the state of relay by the magnetic force of permanent magnet constant.
Reset pulse produces circuit has multiple way of realization, as long as can meet above-mentioned functions.
Embodiment 2
As shown in Figure 2, two ends B1, B2 of the pull-in winding J1 of magnetic latching relay are connected with unbalanced pulse signal, DC power anode is connected with one end of direct solenoid valve coil, its the other end is connected with the main contact A of magnetic latching relay, normally opened contact A2 is connected with the negative pole of DC electrical source, and normally-closed contact A1 sky connects; In addition, the both positive and negative polarity of DC electrical source is communicated with two-end-point c1, c2 of time delay relay coil TD respectively, two-end-point D2, D1 of magnetic latching relay resetting coil J2 are communicated with the both positive and negative polarity of DC electrical source with normally opened contact b1 by the main contact b of time delay relay, and the normally-closed contact b2 sky of its correspondence connects.
Working principle of the present invention is as follows: unbalanced pulse signal realizes the unlatching of DC electromagnetic valve by the pull-in winding J1 controlling magnetic latching relay, and the reseting pulse signal that DC electrical source produces circuit by reset pulse realizes the action of magnetic latching relay resetting coil.
As shown in Figure 3, after unbalanced pulse signal sends, make the pull-in winding J1 of magnetic latching relay obtain electric by the connection of terminal B 1, B2, magnetic latching relay normally opened contact A2 is closed to be also kept closed always, DC electrical source is added on the coil of DC electromagnetic valve simultaneously, and DC electromagnetic valve is opened.At the end of direct solenoid valve opening time, directly close DC electrical source, now the coil losing electricity of DC electromagnetic valve, DC electromagnetic valve closes.
When electrifying DC power supply, time delay relay timing starts, and the coil TD of time delay relay obtains electric simultaneously, and normally opened contact b1 closes, and DC electrical source is directly loaded on the resetting coil J2 of magnetic latching relay, and the resetting coil of magnetic latching relay obtains electric.At the end of time delay relay timing time reaches specified value, action sequence as shown in Figure 3, the coil TD action of time delay relay, normally opened contact b1 disconnects, normally opened contact b2 is communicated with, time delay relay is transformed into off state by on-state and keeps off state always, until input voltage is removed, the DC electrical source be now loaded on magnetic latching relay disconnects, the then resetting coil J2 dead electricity of magnetic latching relay, form the reseting pulse signal of a magnetic latching relay thus, make magnetic latching relay return to original state.
Above embodiment only understands core concept of the present invention for helping; the present invention can not be limited with this; for those skilled in the art; every according to thought of the present invention; the present invention is modified or equivalent replacement; any change done in specific embodiments and applications, all should be included within protection scope of the present invention.
