Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to accompanying drawing 1, mesohigh tapering sealing step direct-acting type electromagnetic valve among the figure, comprise valve body 1, valve gap 7 and be fixed on no magnetic tube 12 on the valve body 1 by valve gap 7, be with electromagnetic coil 13 on the no magnetic tube 12, be connected with moving iron core 10 by moving iron core spring 11 on the adhesive face 14 in no magnetic tube 12, moving iron core 10 is connected with piston 2 in being located at valve pocket by connecting sleeve 9, wherein: described piston 2 comprises piston shelf 16 and passes the tapering pull bar 17 of piston shelf 16 that the top of tapering pull bar 17 is fixed on the piston shelf by locking nut; The bottom of described tapering pull bar 17 has the boss 18 of band tapering, and boss 18 seals by sealing gasket 19 with the heavy stand of being located in piston shelf 16 bottoms; The bottom of described sealing gasket 19 has the soft bevel sealing surface consistent with the hard bevel sealing surface tapering of boss 18; The center of described tapering pull bar 17 is provided with pilot hole 8; Also be provided with on the described piston shelf 16 communicate with the valve fluid passage throttle orifice 15; Piston shelf 16 also by piston spring 4 be located at valve body 1 and be connected with central diaphragm 5 between the moving iron core 10.
Also be provided with piston ring groove on the described piston shelf 16 of present embodiment, piston assembly 3 is installed in piston ring groove.
The described piston assembly 3 of this structure comprises piston ring 21, is separately positioned on flexible rubber ring 22 and the elastic wire 23 gone up in the piston ring 21 in the low groove.
Be provided with seal ring 6 between described valve gap 7 of the foregoing description and the valve body 1.
The top of the described tapering pull bar 17 of present embodiment is provided with diameter and chews 20 less than the gas of pilot hole 8, and gas is chewed 20 and is communicated with pilot hole 8.
The moving iron core 10 of this structure is threaded togather by connecting sleeve 9 and piston 2 usefulness of being located in the valve pocket.
This structure is work like this: electromagnetic coil 13 energisings, when being zero-pressure when the solenoid valve entrance point with outlet end: moving iron core 10 and no magnetic tube 12 have produced the magnetic field adhesive, and gas is chewed 20 and opened, the inner pressure that produces of pressure release valve pocket, move on the moving iron core 10 pulling pistons, valve is opened by electromagnetic coil magnetic force; When the solenoid valve entrance point was mesohigh: moving iron core 10 and no magnetic tube 12 had produced the magnetic field adhesive, gas is chewed 20 and is opened, the inner pressure that produces of pressure release valve pocket, piston promote by pressure medium and move in iron core 10 pullings and move, and valve is opened by pressure medium and electromagnetic coil magnetic force.Electromagnetic coil 13 outages, when being zero-pressure when the solenoid valve entrance point with outlet end: moving iron core 10 resets by the power of moving iron core spring 11, and sealing gas chews 20, and piston 2 resets close port, closed electromagnetic valve by the power of piston spring 4; When the solenoid valve entrance point was mesohigh: moving iron core 10 resetted by the power of moving iron core spring 11, and sealing gas chews 20, and piston 2 resets by the power of piston spring 4, close port, medium flows to the supercharging of valve pocket internal valve cavity by throttle orifice 15, and valve piston is moving by trying hard to recommend of pressure medium and spring, closed electromagnetic valve.
This structure has been utilized from big pilot hole 8 and has progressively been changed over little pilot hole (promptly gas chews 20), make the pressure that it can the big valve pocket of pressure release heavy caliber, form and to use small-bore pilot hole progressively dwindling valve pocket, thereby low power electromagnetic coil 13 can both be opened the valve of high pressure and ultrahigh pressure.Satisfied solenoid valve and can both open, and dwindled the power and the profile of electromagnetic coil 13, on electromagnetic coil 13, also saved cost, also do not needed pilot valve, dwindled overall structure, be convenient to install at high pressure and ultrahigh pressure.
In sum, because the valve with this structure in use, reached zero leakage and reduced user cost.
