The multistage guiding high pressure magnetic valve of a kind of heavy caliber in the present embodiment, is closed as shown in figure 3, being in magnetic valve
During state, when being passed through the media such as water or gases at high pressure, the medium such as water or gases at high pressure is under pressure through piston hole
29 moments flowed into the intracavitary of valve body 1, flowed through first piston 12 by the big balance pipe 23 on big bonnet 9 afterwards, then by first first
The corresponding middle balance pipe 27 of guide assembly 130 flows into the first bonnet 14, due to the first bonnet 14 it is corresponding with second piston 15 in it is flat
Weighing apparatus hole 27 is communicated so that the medium such as water or gases at high pressure is flowed through rapidly to the second bonnet 17, and now inlet pressure is nowhere released
Put, in the presence of piston spring 6, the first spring 13, second spring 16 and each spring force of iron core spring 19, magnetic valve still in
Closed mode；
As shown in Figures 3 to 5, the first step that magnetic valve is started working, magnet coil 21 is powered, under the influence of a magnetic field
Movable core 18 overcomes the resistance of iron core spring 19 to move upwards, opens the small relief hole 33 corresponding to electromagnetic pilot component 120,
The medium moment such as water or gases at high pressure discharges from small relief hole 33, and now electromagnetic pilot component 120 starts pressure release, but still can not
Satisfaction rises piston component 4 and opens the pressure requirements of magnetic valve, i.e., the pressure release intensity of electromagnetic pilot component 120 is not enough；The
Two steps, because the first bonnet 14 is connected with the second bonnet 17 by middle balance pipe 27, after the second 17 pressure release of bonnet, the first bonnet
Pressure moment in 14 diminishes, and second piston 15 overcomes the spring force of second spring 16 to move upwards, and opens the first bonnet 14
On middle relief hole 31, the medium moment such as water or gases at high pressure discharges from the middle relief hole 31 of the first bonnet 14, but nothing
Method, which is met, to be risen piston component 4 and opens the pressure requirements of magnetic valve, i.e. the first guide assembly of electromagnetic pilot component 120 and second
140 pressure release intensity is not enough；3rd step, because the first bonnet 14 is connected with big bonnet 9 by big balance pipe 23, when the first bonnet
After 14 pressure releases, the pressure moment in big bonnet 9 diminishes, and first piston 12 overcomes the spring force of the first spring 13 to move upwards, and
The big relief hole 31 of big bonnet 9 is opened, because the big relief hole 31 of big bonnet 9 is larger, pressure release condition, piston component is fully met
4 corresponding big balance pipes 23 are less than the big relief hole 31 on big bonnet 9, and piston component 4 is moved upwards in the presence of pressure difference, main
Valve port 2 is opened, and the medium such as water or gases at high pressure goes into circulation.
It the above is only the preferred embodiment of the present invention, it is noted that come for those skilled in the art
Say, without departing from the technical principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
