Description
Technical field
The present invention relates to a kind of Mechanical course fields more particularly to a kind of fluid to control solenoid valve.
Background technique
Fluid control solenoid valve is used widely in Industry Control, such as the waterway electromagnetic valve Structure of need in water purifier
Small and exquisite, flexible movements.It remains at present insufficient both ways: first is that existing electromagnetic valve core is upper and lower two pitch cylinders iron core composition,
Adjustable spring is equipped between two pitch circle column iron cores, when constituting magnetic circuit, the magnetic line of force will pass through yoke, upper core, lower core and be formed back
Road, this structure is in tri- air gap of magnetic Circuit Design Shang You, i.e. upper core and yoke, upper core and lower core, lower core and yoke
Between three air gaps, this considerably increases magnetic resistance to need to increase electromagnet size, and increase when guaranteeing same suction
Add energy consumption；Second is that the water of fluid control device part is easy to penetrate into around iron core, it is long cause iron core to get rusty, iron core gap product
Sundries is filled out, causes to act failure of being obstructed, this leverages the working life of electromagnet.
Secondly the prior art is as shown in Fig. 3, is set with Rubber end 5, entire valve chamber 3 and iron in the end of the spool 1-12
It is in a big cavity between core 1-4 and coil 1-1, around water penetration to iron core, in iron core and coil rack inner hole
Between set ring packing 6, but this sealing, due to the opposite sliding between valve rod and ring packing, sealing effect is bad, long it
Ring packing deformation, loses sealing function.
Summary of the invention
The present invention is in view of the deficienciess of the prior art, providing one kind substantially reduces magnetic resistance, in the same suction of guarantee
In the case of, energy consumption is reduced, electromagnet can be made to become smaller in size, reduces the fluid control solenoid valve in space.
The technical scheme to solve the above technical problems is that a kind of fluid controls solenoid valve, which is characterized in that including electricity
Magnet valve valve body and fluid control device, the fluid control device are bolted to connection with electromagnetic valve body；
The electromagnetic valve body includes coil, coil rack, yoke and iron core, the coil winding on the coil rack,
The coil rack includes two end plates, and the coil rack is inserted into the yoke, and the iron core is inserted into the coil
In skeleton, spring is equipped between one end and yoke of the iron core, the other end and spool are integrally formed, and the valve core upper sleeve is equipped with
Ring type seal and seal gasket, the seal gasket are located at the ring type seal lower end；
The seal gasket includes integrally formed sheet rubber, rubber neck and seal plug, and the center of the sheet rubber is equipped with
Cavity is equipped in rubber neck and seal plug, the rubber neck and seal plug, the spool end protrudes into the cavity
Interior, the seal plug is moved synchronously with the spool.
The fluid control device includes the valve chamber that annular shoulder and annular shoulder and spool are formed, and is set respectively on the valve chamber
There are water inlet end and water outlet, channel is equipped between the water inlet end and water outlet.
The beneficial effects of the present invention are: first is that integrated core structure is greatly reduced in magnetic Circuit Design by reducing air gap road
Magnetic resistance when guaranteeing same suction reduces energy consumption, electromagnet can be made to become smaller in size, and reduces space；Two
Be due to use ring type seal and seal gasket, liquid reservoir and electromagnetic coil and iron core is completely separated, thoroughly prevent
Liquid infiltration；Third is that the sealing surface of ring type seal and seal gasket is not influenced by iron core movement, electromagnetism is substantially prolonged
The working life of iron.
Based on the above technical solution, the present invention can also be improved as follows.
Further, the yoke is C-shaped structure.
Further, the edge of the ring type seal is in contact with the annular shoulder.
Further, the sheet rubber lower edge is equipped with annular convex platform.
Further, the top surrounding of the seal gasket is pressed on annular convex platform.
Beneficial effect is: liquid reservoir and electromagnetic coil and iron core is completely separated, thoroughly prevent liquid infiltration, into one
Step sealing.

Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
As shown in Fig. 1~2, a kind of fluid control solenoid valve, including electromagnetic valve body 1 and fluid control device 2, the stream
Member control apparatus 2 is bolted to connection with electromagnetic valve body 1；
The electromagnetic valve body 1 includes coil 1-1, coil rack 1-2, yoke 1-3 and iron core 1-4, and the coil 1-1 is wound on
On the coil rack 1-2, the coil rack 1-2 includes two end plates, and the coil rack 1-2 is inserted into the yoke 1-
In 3, the iron core 1-4 is inserted into the coil rack 1-2, and spring is equipped between one end and yoke 1-3 of the iron core 1-4
1-5, the other end and spool 1-12 are integrally formed, and are set with ring type seal 1-6 and seal gasket 1- on the spool 1-12
7, the seal gasket 1-7 are located at the lower end the ring type seal 1-6；
The seal gasket 1-7 includes integrally formed sheet rubber 1-9, rubber neck 1-10 and seal plug 1-11, the rubber
The center of film 1-9 is equipped in rubber neck 1-10 and seal plug 1-11, the rubber neck 1-10 and seal plug 1-11
Equipped with cavity, the spool 1-12 is protruded into the cavity end, seal plug 1-11 fortune synchronous with the spool 1-12
It is dynamic.
The fluid control device 2 includes the valve chamber 3 that annular shoulder 4 and annular shoulder 4 and spool 1-12 are formed, described
It is respectively equipped with water inlet end 2-1 and water outlet 2-2 on valve chamber 3, channel 2-3 is equipped between the water inlet end 2-1 and water outlet 2-2.
The yoke 1-3 is C-shaped structure.
The edge of the ring type seal 1-6 is in contact with the annular shoulder 4.
The sheet rubber 1-9 lower edge is equipped with annular convex platform 1-8.
The top surrounding of the seal gasket 1-7 is pressed on annular convex platform 1-8.
The working principle of the invention is: water enters from water inlet end, makes iron core band dynamic iron core by electromagnetic induction and is linked as
The spool of one moves upwards, and since spool bottom end is protruded into the seal plug of seal gasket, seal plug and the spool are same
The reason of step movement, in the case where ring type seal and motionless sheet rubber, spool connecting band dynamic sealing plug is moved upwards,
To the closure of control channel, water, which flows into fluid control device, crosses channel from water outlet outflow.Due to reducing magnetic air gap,
To substantially reduce magnetic resistance, when guaranteeing same suction, energy consumption is reduced, electromagnet size can be made to become more
It is small, reduce space；
Secondly because the presence of seal assembly, it is not easy to penetrate into around iron core, not will lead to movement and be obstructed failure, greatly prolong
The working life of electromagnet.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
