In the range of art content to be covered.Meanwhile, in this specification it is cited as " on ", D score, "left", "right", " centre " and
The term of " one " etc., is merely convenient to understanding for narration, and is not used to limit enforceable scope of the invention, its relativeness
It is altered or modified, under without essence change technology contents, when being also considered as enforceable category of the invention.
As shown in figure 3, the present invention provides a kind of air-operated solenoid valve, it includes：
Main valve body 1, with valve pocket 13, air cavity 18 and liquid-inlet 16 and liquid outlet 12, and main valve body 1 be provided with
The inlet channel 17 that the air cavity 18 is communicated；
Main valve plug 14, the main valve plug 14 is hollow tubular structure, is placed in the valve pocket 13, one end of main valve plug 14
It is connected with the liquid-inlet 16, compression spring 15, one end and the valve pocket 13 of compression spring 15 is arranged with outside the main valve plug
Cavity wall abut, the other end abuts with the circumferential projection on main valve plug 14, and the other end of main valve plug 14 and the sealing in valve pocket
Block piece 19 contacts sealing under the pressure of compression spring 15；
Automatically controlled pilot head 11, on main valve body 1, and the sealed valve core 111 of automatically controlled pilot head 11 is placed in inlet channel
In 17, the break-make of inlet channel 17 is controlled；The side of the circumferential projection that compression spring 15 is placed on the main valve plug 14, air cavity 18
Surrounded by the opposite side and the main valve body 1 of the circumferential projection on institute's valve element 14, when the action of automatically controlled pilot head 11 makes inlet channel
17 ventilations, until when the air pressure in the air cavity 18 is more than the pressure of compression spring 15, main valve plug 14 is away from the sealing block piece
19, make main valve plug 14 be connected with the liquid outlet 12.
Used as the liquid main channel of whole air-operated solenoid valve, it is that tube-like structure aperture is big to the main valve plug 14 of the present invention, because
Medium can pass through with current in this water, it is not easy to block, and water cleaning degree be required low；In addition, using automatically controlled pilot head 11
Used as first guiding element, after automatically controlled pilot head obtains electric, inlet channel 17 is opened makes high pressure gas to enter air cavity 18, then acts on
Main valve plug 14 makes main valve plug 14 away from sealing block piece 19, main valve plug 14 and liquid outlet 12 to overcome the pressure of compression spring 15
It is connected, now liquid-inlet 16 is communicated by main valve plug 14 with liquid outlet 12, constitutes fluid passage, is adapted to the field for having air pump
Conjunction is used, convenient control.
Compression spring 15 is all the time pressed on main valve plug 14 on sealing block piece 19 in the present invention, it is ensured that automatically controlled pilot head 11 exists
When being not powered on, main valve plug 14 is in sealing contact with sealing block piece 19, it is ensured that main valve body disconnects with liquid outlet, i.e., gas of the invention
Moving electromagnetic valve is normally off.When the solenoid in automatically controlled pilot head 11 is powered, the sealed valve core 111 of automatically controlled pilot head 11
Lifted because of the active force that electromagnetism is produced, inlet channel 17 is connected with high-pressure air source, when the work that the air pressure in air cavity 18 is produced
After being firmly more than the fluid force of the compression spring force in left side and main valve in-core, main valve plug 14 is moved to the left, makes main valve plug
14 are separated from sealing block piece 19, allow to be entered from liquid-inlet 16 by the pressure fluid of main valve plug endoporus, from liquid discharge
Mouth 12 sprays, and realizes valve opening, fluid communication, it can be seen that, liquid mainly flows through from main valve plug endoporus, only needs main valve in-core
Hole aperture is enough, you can flow through the impurity in water, it is to avoid blocking, improves the service life of air-operated solenoid valve.The present invention's
Air-operated solenoid valve can be used as high-pressure water valve.
To increase sealing, above-mentioned sealing block piece 19 is made up of elastic soft material；Main valve plug 14 and the sealing phase of block piece 19
The contact jaw of contact is also the elastic portion by made by elastic soft material.To reach zero leakage, above-mentioned main valve plug 14 and sealing gear
The position that part 19 contacts, because main valve body adopts stainless steel material, belongs to hard using the elastic soft material of press-in polymer
Material, although main valve plug 14 is also stainless steel material making, the position of main valve plug 14 and the sealing contact of block piece 19 is using pressure
Enter the elastomeric soft materials of polymer, this elastomeric soft materials can be the materials such as rubber, and it realizes the sealing of soft or hard combination, so
Reliable closed effect can be reached, No leakage is finally reached.
Above-mentioned automatically controlled pilot head 11 includes sleeve, the sealed valve core 111, static iron core and solenoid, sealed valve core 111
With static iron core in sleeve, solenoid is located at sleeve outer wall, and sleeve bottom end is fixed on main valve body 1.In the present embodiment
Automatically controlled pilot head is a kind of electromagnetic valve guide head, and its concrete structure not limited to this, its need meet following functions：Obtain electric
Afterwards, sealed valve core action is made, and then opens above-mentioned inlet channel；When power is off, sealed valve core closing inlet channel, i.e. normality
Lower inlet channel is closure state.
As shown in Figures 2 and 3, the present invention also provides a kind of air-powered electromagnetic valve group, and it includes that at least one is as above
Air-operated solenoid valve, the main valve body 1 of all air-operated solenoid valves constitutes same multichannel valve member 2, and the multichannel valve member 2 is provided with liquid
Passage, communicate with the fluid passage liquid general import 3, and that total inlet channel and total inlet channel are communicated
Total air inlet 5, the fluid passage is connected with the liquid-inlet in each air-operated solenoid valve, and total inlet channel is pneumatic with each
Inlet channel in magnetic valve is communicated.Above-mentioned air-operated solenoid valve can be combined into multigroup valve by the present invention according to requirements
Group, its can arbitrary arrangement, convenient processing and safeguard, take up room little；The air-powered electromagnetic valve group of the present invention is controlled than existing cylinder
Ball valve water valve group fixing link it is few, purchase cost is low, takes up room little.
To increase safety in utilization, the safety valve 4 being associated with fluid passage is additionally provided with above-mentioned multichannel valve member 2.
In sum, air-operated solenoid valve of the invention and air-powered electromagnetic valve group, its main valve plug is used as whole air-powered electromagnetic
