Working principle of the present utility model is:
The seal ring 22 of guide electromagnetic valve main valve 4 lower surface under normally off pushes against the bulge loop 32 on main valve seat 7, and the sealing station 21 of secondary valve 5 lower surface also pushes against pressure relief vent 20, thus medium cannot be flowed into from influent stream road 11, goes out runner 12 and flows out.Now, medium flows into from influent stream road 11, by the pilot hole 19 on main valve 4, then flows through the gap of secondary valve 5 outer wall and main valve 4 inwall, the second runner 26, the 3rd runner 27, makes medium be full of the cavity of secondary valve more than 5.When control gear is in opening state, electromagnetic coil 10 is energized produce magnetic field and cause dynamic iron core 9 to move upward with close static iron core 8, extrude stage clip 14 simultaneously, and dynamic iron core 9 can drive valve stem casing 29 to move upward together with valve rod 3, open pressure relief vent 20 with this, make medium can flow to out runner 12 from pressure relief vent 20.And at this moment, the pressure of medium in main valve 4 upper chambers is discharged and rapid drawdown from pressure relief vent 20, but in influent stream road 11, pressure medium does not reduce, and precisely, the pressure medium acting on main valve 4 lower surface is greater than the pressure of main valve 4 inside; Furtherly, act on active force that main valve 4 lower surface upwards pushes away to be greater than and to act in main valve 4 to the active force pressed down, so, act on active force that main valve 4 lower surface upwards pushes away and can promote main valve 4 and move up, and be communicated with influent stream road 11 with this and go out runner 12 for media flow.
When control gear is in closed condition, electromagnetic coil 10 power-off, electromagnetic coil 10 can not produce magnetic field, dynamic electromagnetic force between iron core 9 and static iron core 8 disappears, valve stem casing 29 promotes dynamic iron core 9 and valve rod 3 away from static iron core 8 under the elastic force effect of stage clip 14, secondary valve 5 and valve rod 3 synchronously move down and promote main valve 4 and move down, until the sealing station 21 of secondary valve 5 lower surface pushes against pressure relief vent 20 and the seal ring 22 of main valve 4 lower surface pushes against bulge loop 32, thus prevent medium from flowing through from main valve 4 and secondary valve 5, disconnect influent stream road 11 with this and go out runner 12.
If medium has in the chamber that leaks into residing for electromagnetic coil 10, then the pressure of this chamber can raise, the medium leaked can flow through first flow 25 and be full of cavity in Safety valve body 23, promote safe spool 24 along with the rising of leaking medium pressure to move up, and then promotion block 28 moves, when pressure height to a certain extent time, too high pressure medium can promote block 28 and depart from Safety valve body 23, reduces the force value of chamber residing for electromagnetic coil 10 with this.
The foregoing is only preferred embodiment of the present utility model, not for limiting protection domain of the present utility model.All within the utility model claim, any amendment done, equivalent replacement and improvement etc., all should be included within protection domain of the present utility model.
