Abstract
The invention discloses an electromagnetic valve which comprises water inlets and a water outlet. The normally open water inlet and the normally closed water inlet are arranged on the lower right side of an electromagnetic valve housing. The water outlet is arranged on the lower left side of the electromagnetic valve housing. An inner end of the water outlet and inner ends of the two water inlets are communicated with a water cavity. Two mutually parallel vertical cavities are arranged at the upper end of the water cavity. A normally open valve magnet core and a normally closed valve magnet core are disposed in the two vertical cavities respectively. A rubber seal cover is arranged at the lower end of a small-diameter column. Another rubber seal cover is arranged at the lower end of the normally closed valve magnet core. A coil is arranged on the outer lower portion of the vertical cavity in which the normally open valve magnet core is located. Another coil is arranged on the outer upper portion of the other vertical cavity in which the normally closed valve magnet core is located. The two coils are respectively connected with a power supply. A switch is arranged on a circuit between each coil and the power supply. The electromagnetic valve is sued for negative pressure irrigation systems.
Description
Technical field:
The present invention relates to the solenoid valve of a kind of water valve, particularly a kind of agricultural irrigation.
Background technique:
The plant negative pressure water-supply technology is to supply water to plant with the soil unsaturated state, has water saving, energy-conservation advantage comes into one's own.This negative pressure water supply process is, starts to form negative pressure and feed water to soil, and when flow of water balance, feedwater stops, when negative pressure is lost, again start form negative pressure after, again to soil water supply, this way of supplying water needs a kind of solenoid valve with mutual exclusion function.Existing two-bit triplet solenoid valve need to arrange control structure and just can satisfy the demand before two imports, structure is complicated, and cost is higher.
Summary of the invention:
The purpose of this invention is to provide a kind of solenoid valve simple in structure and the plant negative pressure feedwater that cost is low that has.
The technological scheme that realizes the object of the invention is, a kind of solenoid valve, comprise water inlet and osculum, it is characterized in that: the right side of solenoid valve lower housing portion have two parallel often drive water hole and normally closed water inlet into, the inner port of this two water inlet is communicated with water cavity respectively, there is an osculum in the left side of this solenoid valve lower housing portion, the inner port of this osculum is communicated with above-mentioned water cavity, the upper end of above-mentioned water cavity is provided with two vertical chambeies that parallel, normally open valve magnetic core and normally close valve magnetic core place respectively in above-mentioned two vertical chambeies, be provided with stage clip between the upper-end surface in the upper-end surface of above-mentioned normally closed magnetic core and vertical chamber, be arranged with stage clip on the above-mentioned minor diameter cylinder of often opening the magnetic core bottom, the lower end of this minor diameter cylinder is provided with rubber closure, the lower end of normally closed magnetic core is provided with rubber closure, above-mentioned two rubber closures respectively ring surface with the inner port of above-mentioned Chang Kaishui hole and normally closed water inlet are relative, bottom in the vertical cavity outside of often opening the magnetic core place is provided with coil, normally closed magnetic core the top in another vertical cavity outside be provided with coil, two above-mentioned coils are connected with power supply respectively, respectively are provided with a switch on the circuit between this coil and the power supply.
The present invention has advantages of simple in structure low with cost compared with the prior art.
Description of drawings:
Fig. 1 is plan view of the present invention; Fig. 2 is the A-B turnover cut-away view of Fig. 1, and Fig. 3 is the A-C turnover sectional view of Fig. 1.
Embodiment:
In conjunction with above-mentioned accompanying drawing the present invention is elaborated, the right side of solenoid valve lower housing portion have two parallel often drive water hole 2 and normally closed water inlet 3 into, the inner port of this two water inlet is communicated with water cavity respectively, there is an osculum 1 in the left side of this solenoid valve lower housing portion, the inner port of this osculum is communicated with above-mentioned water cavity, the upper end of above-mentioned water cavity is provided with two vertical chambeies that parallel, normally open valve magnetic core 7 and normally close valve magnetic core 10 place respectively in above-mentioned two vertical chambeies, be provided with stage clip between the upper-end surface in the upper-end surface of above-mentioned normally closed magnetic core and vertical chamber, be arranged with stage clip 5 on the above-mentioned minor diameter cylinder of often opening the magnetic core bottom, the lower end of this minor diameter cylinder is provided with rubber closure 4, the lower end of normally closed magnetic core 7 is provided with rubber closure 8, be provided with stage clip 9 between the upper-end surface of this rubber closure 8 and described water cavity, above-mentioned two rubber closures respectively ring surface with the inner port of above-mentioned Chang Kaishui hole and normally closed water inlet are relative, bottom in the vertical cavity outside of often opening the magnetic core place is provided with line, 6, normally closed magnetic core the top in another vertical cavity outside be provided with coil 11, two above-mentioned coils are connected with power supply respectively, respectively are provided with a switch on the circuit between this coil and the power supply.Above-mentioned Chang Kaishui hole and normally closed water hole respectively with normal boiled water pipe and normally closed cross current, above-mentioned outlet pipe is communicated with outlet pipe.
Working principle of the present invention is, when the normally closed of solenoid valve with when often opening the magnetic core no electric circuit, the stage clip that the caulking gum of these two magnetic core lower ends covers will often drive the water hole into respectively under spring action separately and normally closed water inlet inner port is opened and sealed, at this moment, solenoid valve is supplied water by negative pressure; When negative pressure is lost needs recovery negative pressure, should give often opening and normally closed magnetic core coil electricity of solenoid valve, this often drives the water hole into and closes, and open normally closed water inlet, the negative pressure of losing is recovered, and negative pressure is recovered rear electromagnetic valve magnetic core coil blackout, recovers negative pressure and supplies water to plant, above-mentioned to magnetic core energising employing pulse electrifying, the time is generally the several seconds.This solenoid valve uses very convenient in negative pressure water service system.
