Description
Technical field
The utility model relates to a kind of bistable electromagnetic valve.
Background technique
Traditional bistable electromagnetic valve all is the structure of adopting under looking like generally: when coil is not switched on, moving iron core does not move, and medium is by the pressurized hole above the rubber membrane, make the supercharging of rubber membrane upper chamber, this moment since the lifting surface area of epicoele greater than the lifting surface area of cavity of resorption, rubber membrane is failure to actuate, and tightly suppresses water outlet; When coil electricity, moving iron core action, electromagnetic valve guide is partly opened, and the medium that causes being in the rubber membrane epicoele is by the pressure relief vent off-load, and at this moment, the rubber membrane upper cavity pressure is less than cavity of resorption, and rubber membrane is action upwards, and the solenoid valve main valve is opened.
And the structure of traditional pressure relief vent do more complicated, earlier by the release aperture, the mistakes water lines of a complexity by valve seat inside then links to each other with pressure relief vent in the valve body, then pass through in the valve body one water lines, the water outlet of feeding valve body.Because a pressure relief vent is all arranged in valve seat, valve body, therefore when the fabrication and processing of valve seat, valve body, increased difficulty, reject rate is high, has improved cost, and the volume of valve body is also very big simultaneously.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple and reasonable for structure, the bistable electromagnetic valve of easy processing at above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this bistable electromagnetic valve, comprise valve body part and electromagnetism main control part, wherein the electromagnetism main control part comprises by case, be provided with coil block in the closed chamber that base is formed, iron core, magnet, the electromagnetism valve head and the valve seat of spring and rubber plug, be provided with the elastomer diaphragm and the rubber membrane skeleton of matched together between the valve of valve seat and valve body, it is characterized in that described rubber membrane skeleton has the axis of guide that a middle part has an axial hole that communicates with the valve body water outlet, the top of the axis of guide slidably is arranged in the axis hole of valve seat, and and the axis hole of valve seat between be provided with seal ring, a Returnning spring is enclosed within on the axis of guide; The interposition at described valve seat top is equipped with a cavity, and cavity middle part is provided with over against top rubber plug and the pressure relief vent that is communicated with the axial hole of described valve seat axis hole and rubber membrane skeleton; Described elastomer diaphragm is provided with the pressurized hole that communicates with the valve inleting water mouth, and described valve seat is provided with the water conservancy diversion aperture that is communicated with described pressurized hole and pressure relief vent.
Described electromagnetic valve coil adopts 30 Ω coils.
Compared with prior art, advantage of the present utility model is: the pressure relief device of this solenoid valve is changed conventional labyrinth, medium directly feeds axial hole in the axis of guide by the pressure relief vent in the valve seat, then flow into the valve body water outlet, thereby it is simple in structure, be beneficial to the making of valve body, valve seat, thereby can reduce cost and dwindle the volume of valve body; Solenoid valve adopts 30 Ω coils in addition, can reduce power consumption greatly when work.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, bistable electromagnetic valve of the present utility model mainly is made up of valve body part and electromagnetism main control part, wherein:
Described electromagnetism main control part mainly includes electromagnetism valve head and valve seat 6, and the electromagnetism valve head mainly is to be made of case 1, coil carrier 3, coil 4, movable core 22, secured core 24, magnet 25, spring 23, rubber plug 5, base 2 etc.Wherein said coil carrier 3, coil 4, movable core 22, secured core 24, magnet 25, spring 23 and rubber plug 5 are contained in the space of a shielding of being made up of jointly case 1 and base 2.Specifically as shown in Figure 1, coil carrier 3 directly is coated on when injection molded outside the base of having made 2, and both injection mouldings are in together, and coil 4 is on coil carrier 3.Magnet 25, secured core 24, movable core 22 and rubber plug 5 from top to bottom are arranged in the base 2 successively, and secured core 24 has an annular groove, in be provided with the O RunddichtringO, to guarantee the sealing between secured core and base, spring 23 is enclosed within outside the movable core 22.
Described valve seat 6 is positioned at the below of electromagnetism valve head, is fixed together with the electromagnetism valve head.In valve seat crown center position one cavity is arranged, the cavity middle part is provided with pressure relief vent 21, and pressure relief vent is over against the rubber plug 5 of top electromagnetism valve head.Valve seat in pressure relief vent 21 belows has an axial bore 20 that connects with this pressure relief vent, is used for cooperating with the axis of guide 17 slippages of rubber membrane skeleton 16.Valve seat in pressure relief vent 21 outsides is provided with water conservancy diversion aperture 7, and water conservancy diversion aperture 7 connects the cavity at valve seat top.
Described valve body 13 is assembled in valve seat 6, and the rubber membrane skeleton 16 that elastomer diaphragm 10 is installed with between the valve of valve body and is assembled in this elastomer diaphragm in valve seat.Wherein have pressurized hole 11 on the elastomer diaphragm, this pressurized hole 11 is communicated with the water intake 15 of valve body and the water conservancy diversion aperture 7 of valve seat.Rubber membrane skeleton 16 has an axis of guide 17, and the top of the axis of guide and 20 slippages of the axis hole on the valve seat are joined.And two road annular grooves are arranged on the axis of guide 17, in be equipped with an O RunddichtringO 18, to guarantee the sealing between the axis of guide and valve seat axis hole.There is axial hole 18 at the middle part of the axis of guide 17, pressure relief vent 21 on these through hole 18 connection valve seats and the water outlet 12 on the valve body.The axis of guide is with a Returnning spring 8 outward, and two of spring withstands on respectively on valve seat and the elastomer diaphragm.
In order to reduce the power consumption of this solenoid valve when working, electromagnetic valve coil 4 adopts 30 Ω coils in addition.
The working principle of this solenoid valve is as follows:
A. coil 4 is not switched on, moving iron core 22 is failure to actuate, rubber plug 5 is pushed down the pressure relief vent 21 on the valve seat, and medium enters the pressure chamber 9 that elastomer diaphragm and valve seat are formed from the water intake 15 of valve body by the pressurized hole on the elastomer diaphragm 11, enter into moving iron core space on every side again, until being full of whole cavity.This moment is owing to pressure chamber 9 and water-inlet cavity 14 are separated by elastomer diaphragm 10, and the active area of epicoele makes pressure chamber 9 and water-inlet cavity 14 form pressure difference greater than cavity of resorption, and this pressure official post elastomer diaphragm 10 is failure to actuate, connect together tightly with valve body 13, valve body is in the pass water state.
B. after coil 4 energisings, moving iron core 22 is upspring, pressure relief vent 21 on rubber plug 5 servo-actuated iron cores are lifted off a seat, pressure chamber 9 is communicated with the water outlet 12 of valve body, and medium flows into valve body water outlet 12 by pressure relief vent 21 by the through hole on the rubber membrane skeleton 18, and this moment, epicoele pressure reduced, current overcome spring 8 power and back down elastomer diaphragm 10, elastomer diaphragm 10 is upwards moved along the axis of guide 17 together with rubber membrane skeleton 16, valve opening, valve body is in water state.
