Specific embodiment
As shown in figure 1, being high-pressure mini 2/2-way electromagnetic valve structure of the present utility model, which is mainly by valve body 13, line
The wire that valve element 2, valve seat 3, the spring 4 for forcing in valve element, residual shim 7, coil block 1 in coil assembly 1, valve body 13 is drawn
10th, shell 11 is constituted.The irregular winding window structure that wherein coil block 1 is combined using polygon and rectangle, this example
The window structure (referring to the section profile of Fig. 1 coils) combined using trapezoidal and rectangle, gear unnecessary in electromagnetism iron circuit
Ferrum part is designed to coil window, and the space that the coil window of this irregular structure takes does not interfere with magnetic circuit, on the contrary fully
Inner space is make use of, in the case where the coil turn needed for electromagnetic valve reliably working is ensured, electromagnetic valve diameter is reduced, electricity
The quality and volume of magnet valve is reduced, and realizes the purpose of design of electromagnetic valve miniaturization.
As shown in Fig. 2 valve element 2 separates schematic diagram with valve seat 3, wherein valve element 2 docks to form sealing pair with valve seat 3, control
The circulation and cutout of gas medium.Spring 4 is located in the middle part of whole electromagnetic valve, is that valve element 2 provides closing forces.
The valve seat 3 shown in valve element 2 and Fig. 4 shown in Fig. 3, can be clearly seen the position of planar end surface 22 and trapezoid boss 31；
The planar end surface 22 of valve element 2 is docked with seal form with the trapezoid boss 31 of valve seat 3, and this seal form is sealed for bacterium shape.In order to
Ensure electromagnetic valve reliably sealing, and reduce the rigid collision during valve element 2 is worked with valve seat 3, the planar end surface 22 of valve element 2 as far as possible
For non-metallic material, 3 trapezoid boss 31 of valve seat is metal material.Planar end surface 22 selects rigid plastics, and trapezoid boss 31 is stainless
Steel or aluminium alloy.Above material is preferred forms, in addition also can adopt metal material or adopt non-metallic material
Matter.At the same time O shapes rubber seal 8, plastics back-up ring 9 and metallic gasket more than 5 are sequentially provided with valve seat 3 and 2 connection end of valve element
Road redundant seal.Sealing of the electromagnetic valve under environment under high pressure has greatly been ensured using above sealing structure form.
The cooperation that slides axially between valve element 2 and coil block 1 is oriented to, when solenoid valves, by valve element 2 and line
Coil assembly 1 forms magnetic circuit passage, and electromagnetic attraction is produced at the valve element air gap 12, and now spring 4 shrinks, 3 points of valve element 2 and valve seat
From gas medium circulation；After electromagnetic valve power-off, as 4 elastic force of spring is acted on, spring 4 extends and for valve element 2 to be pressed on valve seat 3
On, medium is sealed.As 12 big magnetic force of air gap reduces, big this ultimate principle of 12 little magnetic force of air gap is not difficult to learn gas
The size of gap 12 affects the movement travel of valve element 2, and metallic gasket 5 can be with the size of accurate adjustment air gap 12, so as to accurate adjustment
The movement travel of valve element 2, by matching metallic gasket 5 during assembling, that is, is exactly to change the thickness of metallic gasket 5 to adjust valve element 2
Stroke, the action message of electromagnetic valve work is ensured with this.
Filter 6 is provided with into one end of valve element 2 in gas medium, installed in vent stack road air inlet port, in reality
In work, gas medium is likely to occur fifth wheel, valve element 2 can be caused stuck or the accident such as dielectric leakage, and filter 6 is effectively prevented
Fifth wheel in medium is entered inside electromagnetic valve, it is to avoid accident occurs.
2 structure chart of valve element as shown in Figure 3, on this valve element 2, the connection end of valve element 2 and valve seat 3 is provided with a plurality of ventilation side
Duct 21.Under same pressure, the number in side opening road 21 of ventilating is inversely proportional to gas medium flow velocity, 21 quantity of ventilation side opening road
Can be with effective control flow velocity.Require to design corresponding ventilation side opening road number 21 according to gas with various velocity of medium, it is relatively reasonable
Ventilation side opening road 21 is counted as three or four.
During electromagnetic valve work, fifth wheel may be produced and affect sealing after the multiple action vertically of valve element 2, in order to anti-
The only generation of fifth wheel, carries out metal surface chemical deposit to valve element 2.It is unnecessary that metal surface chemical deposit not only effectively prevent
The generation of thing, and the wearability of valve element 2 is improve, while also improving the corrosion resistance and antioxidation of electromagnetic valve soft magnetic materials
