Description
Technical field
The utility model belongs to valve technology field, particularly a kind of solenoid valve.
Background technique
Existing solenoid valve comprises valve body, electromagnetic coil and valve gap, and electromagnet core is arranged in the valve gap, is provided with diaphragm between valve body and the valve gap, by cooperating and seal the conducting that realizes solenoid valve and close between electromagnet core and the diaphragm.Usually, diaphragm adopts plastics, rubber or its combination to be made, and regular meeting occurs because of the poorly sealed close leakage phenomenon that causes between diaphragm and the electromagnet core solenoid valve normally being used when reality is used.Simultaneously, another shortcoming of traditional electrical magnet valve be between electromagnet core and the valve gap the gap seldom, it is bigger to make electromagnet core be subjected to the resistance of medium when shrinking, and has directly influenced the sensitivity of solenoid valve.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the existing the problems referred to above of present solenoid valve, and a kind of structure improved solenoid valve is provided, and makes it have good seal performance, highly sensitive, characteristic of reasonable structure.
For achieving the above object, the utility model has adopted following technical proposal: this solenoid valve comprises the valve gap on valve body and the valve body, there are entry end and outlet end in the inside of valve body, valve gap is fixed on the valve body by a block pressur plate, electromagnet core and spring are housed in the valve gap, valve gap is provided with electromagnetic coil outward, between valve gap and valve body, also be provided with diaphragm, surface of contact center with diaphragm in the valve body is a liquid outlet opening, has an annular groove around it, and liquid outlet opening communicates with outlet end, liquid-entering hole is arranged in the annular groove, liquid-entering hole communicates with entry end, has an equalizing orifice in the diaphragm at least, and equalizing orifice is in the pairing position of annular groove, it is that material is made that diaphragm adopts rubber, be embedded with a metal body in the diaphragm, at the center of diaphragm one through hole arranged, the electromagnet core roof pressure is in this through hole.
This solenoid valve seals by diaphragm.Electromagnetic coil do not have the energising state under, electromagnet core be at roof pressure under the effect of spring in the through hole of diaphragm; Simultaneously, diaphragm is close to valve body surface, and the medium in the liquid-entering hole can't be entered the liquid outlet opening from annular groove.Only after the electromagnetic coil energising, electromagnet core against the force of the spring under the effect in magnetic field inwardly shrinks, diaphragm just can back down diaphragm under the effect of entry end pressure medium, make medium enter liquid outlet opening by annular groove and flow to the outlet end of valve body, also just makes this solenoid valve conduction.
In above-mentioned solenoid valve, electromagnet core is a hexagon.Do not switch on the electromagnet core roof pressure in through hole the time at electromagnetic coil, and just there is certain space valve gap inside, and liquid medium can enter by the equalizing orifice of diaphragm in this space.After the electromagnetic coil energising, electromagnet core will inwardly shrink.Is the electromagnet core shaped design hexagon, makes to leave certain clearance between electromagnet core and the valve gap, and the medium that will be convenient in the valve gap flows out valve gap, and electromagnet core is shunk fast.
In above-mentioned solenoid valve, it is that material is made that valve gap preferably adopts stainless steel.Adopt stainless steel can prolong the working life of valve gap.
Compared with prior art, advantage of the present utility model is:
1, because diaphragm has adopted rubber to make, so the favorable sealing property between diaphragm and the valve body has improved the quality of this solenoid valve product.
2, electromagnet core is shaped as hexagon, can reduce resistance, and electromagnet core is shunk fast, has improved the sensitivity of this solenoid valve.

Embodiment
As shown in Figure 1, the solenoid valve that provides of the utility model comprises parts such as valve body 1, valve gap 2, pressing plate 4, electromagnet core 5, spring 6 and electromagnetic coil 7.There are entry end 11 and outlet end 12 in the inside of valve body 1.By entry end 11 and outlet end 12 this solenoid valve is connected on the pipeline.Valve gap 2 is positioned at the top of valve body 1, and is anchored on the valve body 1 by screw 40 with a block pressur plate 4.In the present embodiment, valve gap 2 is that the employing stainless steel is a material, and pressing plate 4 adopts metallic material.
As shown in Figure 1, be provided with a diaphragm 3 between valve gap 2 and valve body 1, the shape of diaphragm 3 as shown in Figure 2.Be embedded with a metal body 31 at diaphragm 3, this metal body 31 plays a supportive role, and makes diaphragm 3 in use keep certain shape.There is a through hole 32 at the center of diaphragm 3, and it is conical that the aperture of through hole 32 is, and the head of electromagnet core 5 has the shape that matches therewith.
As shown in Figure 1, electromagnet core 5 and spring 6 are arranged in valve gap 2.Under the effect of spring 6, electromagnet core 5 roof pressures make through hole 32 not conductings of place on the through hole 32 of diaphragm 3.The outside of valve gap 2 is electromagnetic coils 7.In the present embodiment, be provided with a support 8 that is connected with valve body 1, electromagnetic coil 7 is fixed on the support 8.
As shown in Figure 3, on this solenoid valve, there is a liquid outlet opening 14 at the center, surface of contact place with diaphragm 3 in the valve body 1, around it annular groove 10 is arranged, and several liquid-entering holes 13 are arranged in the annular groove 10.Liquid-entering hole 13 communicates with the entry end 11 of valve body 1, and liquid outlet opening 14 communicates with the outlet end 12 of valve body 1.
Do not have at electromagnetic coil 7 under the state of energising, obviously electromagnet core 5 makes liquid-entering hole 13 not communicate with liquid outlet opening 14 on the through hole 32 of roof pressure under the effect of spring 6 at diaphragm 3.For the medium that prevents liquid-entering hole 13 places backs down diaphragm 3, on diaphragm 3, have an equalizing orifice 30, a small amount of medium is entered in the valve gap 2 by this equalizing orifice 30.After electromagnetic coil 7 energisings, electromagnet core 5 shrinks.At this moment, liquid-entering hole 13 communicates with liquid outlet opening 14, and this solenoid valve is on state.Simultaneously, a small amount of medium in valve gap 2 also will flow out.Therefore, electromagnet core 5 adopts hexagon, and can make between electromagnet core 5 and the valve gap 2 has bigger space, is convenient to electromagnet core 5 and shrinks fast.
As shown in Figure 1, entry end 11 is to also being provided with a filter screen 9 in the valve body 1 between the liquid-entering hole 13 in the present embodiment, and the outer end of filter screen 9 is filter covers 90, and filter cover 90 connects with valve body 1 by screw thread.By filter cover 90, filter screen 9 is fixed in the valve body 1.Because filter cover 90 and valve body 1 by scyewed joint, so can also unload filter screen 9 after this solenoid valve uses a period of time, clean or change.The shape of filter screen 9 is generally cylindrical shape.This filter screen 9 is set, can purifies water, prevent the granular foreign material, and prolong the working life of solenoid valve by this solenoid valve.
The solenoid valve that the utility model provides is particularly useful for fields such as automatic heating equipment, washing machine, dry cleaning machine and water heater.
