Diaphragm, the dynamic iron core component is arranged at the top of the main valve plug, and the plunger tube is placed on outside the dynamic iron core component, institute
Stating coil assembly, to be arranged at the plunger tube outer and with nut check, is provided between the dynamic iron core component and the plunger tube
For the back-moving spring of dynamic iron core component, wherein, the bottom surface of the dynamic iron core component corresponds to be opened up on the position of the pilot hole
There is accommodating cavity, guide's bore seal assembly is provided with the accommodating cavity, screen pack is provided with the inlet.
Especially, guide's bore seal assembly includes Packing spring and the elder generation being arranged at from inside to outside in the accommodating cavity
Guide hole sealing gasket.
Especially, sealing is provided between the valve body and the bonnet and between the bonnet and the plunger tube
Circle.
Especially, the screen pack is the long pyramidal structure of one end open, and its openend coordinates the internal diameter of inlet to set,
And the openend of the screen pack is arranged in inlet by back-up ring.
Especially, the screen pack is made up of stainless steel material.
Beneficial effects of the present invention are, compared with prior art the dynamic iron core component of the pilot type diaphragm electromagnetic switch valve
The seal assembly set between bottom surface and pilot hole, while install filter additional in the inlet, valve is not only had more excellent
Good sealing, and there is contamination resistance, the cleannes requirement to working media is lowered significantly, is effectively increased electromagnetism and is opened
Close reliability and the life-span of valve.

Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1 and Fig. 2, in the present embodiment, a kind of pilot type diaphragm electromagnetic switch valve includes valve body 1, main valve
Core 2, dynamic iron core component 3, plunger tube 4, diaphragm 5 and coil assembly 6, the valve body 1 are provided at both ends with the inlet 7 being connected
With liquid outlet 8, the main valve plug 2 is arranged on the valve body 1 by bonnet 9, and corresponding to liquid at the center of the main valve plug 2 leads to
Road offers pilot hole 10, and the diaphragm 5 for separating inlet 7 and liquid outlet 8 is provided with the main valve plug 2, described dynamic
Core assembly 3 is arranged at the top of the main valve plug 2, and the plunger tube 4 is placed on outside the dynamic iron core component 3, and the coil is total
It is arranged at outside the plunger tube 4 into 6 and is locked with nut 11, use is provided between the dynamic iron core component 3 and the plunger tube 4
In the back-moving spring 12 of dynamic iron core component 3, endoporus of the dynamic iron core component 3 along the plunger tube 4 moves up and down, the dynamic iron
The bottom surface of core assembly 3 corresponds to and accommodating cavity 13 is offered on the position of the pilot hole 10, in the accommodating cavity 13 from inside to outside according to
It is secondary to be provided with Packing spring 14 and pilot hole sealing gasket 15, to increase the sealing at poppet port.
Screen pack 16 is provided with the inlet 7, can effectively filter out the impurity in working media.The screen pack 16
It is made of stainless steel, it is the long pyramidal structure of one end open, and its openend coordinates the internal diameter of inlet 7 to set, and the mistake
The openend of filter screen 16 is arranged in inlet 7 by back-up ring 17.
Sealing ring is provided between the valve body 1 and the bonnet 9 and between the bonnet 9 and the plunger tube 4
18.To increase the sealing of electromagnetic switch valve.
During work, dynamic iron core component 3 opens the pilot hole 10 on main valve plug 2, the upper cavity pressure of valve body 1 is declined rapidly,
Pressure difference is formed between main valve upper and lower cavity, promotes diaphragm 5, main valve plug 2 to move up by the pressure differential of medium, valve is opened, and is now flowed
Body medium enters valve body 1 after the impurity screening of screen pack 16, is flowed out by outlet；When dynamic iron core component 3 closes pilot hole 10
When, fluid media (medium) is rapidly from the aperture 7 of diaphragm 5, into the epicoele of valve body 1, make valve body about 1 cavity pressure it is equal, the He of dynamic iron core component 3
Main valve plug 2 closes valve in the presence of back-moving spring 12.
