Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of bistable electromagnetic valve of the utility model comprises interconnective valve body 10 and valve seat 1, also comprises the shell 14 that is fixedly connected on valve body 10 tops, be that agent structure of the present utility model is valve seat 1, valve body 10 and shell, generally be made by metallic material.Form a cavity between described shell 14 and the valve body 10, form another cavity between described valve body 10 and the valve seat 1.
Be provided with electromagnet assembly in described shell 14 and the valve body 10 formed cavitys, described electromagnet assembly comprises the static iron core 16 and the moving iron core 21 of coaxial setting, be located at first spring 18 between static iron core 16 and the moving iron core 21, the coil brace 13 of being located at static iron core 16 and moving iron core 21 peripheries is with coil 17.Described coil 17 is connected with power supply connecting head (not shown), is used to connect external power to coil 17 energisings.Described valve body 10 is provided with osculum 22, and the position of described osculum 22 is corresponding with the position of moving iron core 21, and the utility model is with moving separate the switch that closure realize osculum 22 of iron core 21 with osculum 22.Electromagnet assembly structure and prior art be essential distinction not, no longer repeats.
Be worth being understood that further coil described in the utility model 17 peripheries are provided with iron-clad 12, play the effect of protection coil 17.Be provided with concentrating flux plate 11 between described coil brace 13 and the moving iron core 21 simultaneously, described iron-clad 12 is connected with concentrating flux plate 11, and iron-clad 12 forms complete magnetic conduction device with concentrating flux plate 11.
Described iron-clad 12 tops are fixed with magnet 15.After the energising of coil 17 forwards, coil 17 produces magnetic field, and moving iron core 21 moves upward, and realizes that moving iron core 21 separates with osculum 22, and osculum 22 is opened, and fluid is from osculum 22 processes.At this moment, because 15 pairs of moving iron core 21 magnetic forces of magnet, even coil 17 outages, moving iron core 21 also can keep separated state with osculum 22, thereby reaches the power saving purpose.Close osculum 22 as need, only need coil 17 reverse energisings are got final product.
Described valve seat 1 forms water intake 2 and water outlet 25, and water outlet 25 inner ends are provided with diaphragm unit, and described diaphragm unit is made up of diaphragm support 4 and the diaphragm of being located on the diaphragm support 45, and described diaphragm 5 is provided with water inlet 23.
