As Fig. 3～shown in Figure 4, in comprising, establishes by reduction valve assembly 3 the spool housing 7 and the pressure-regulating device of spool 6, spool 6 is made up of valve rod 61 and seal valve seat 62, spool housing 7 and valve rod 61 include a thick shell of column and a buttress shaft section, all connect between thick shell of column and the buttress shaft section by the transition conical surface, valve rod also is provided with one and is tightly connected 63 in buttress shaft section end, be provided with toroidal cavity between valve rod buttress shaft section and the spool housing, be provided with O RunddichtringO 81 between thick shell of column of valve rod and the spool housing 7, O RunddichtringO 82 and 83 set between the thick shell of column of spool housing and buttress shaft section and the valve body is all by groove installing and locating set on the external wall of valve core shell; Be provided with in thick, buttress shaft section transition conical surface place on the spool housing and be used for radially vent that decompression gas circuit suction port P0 is connected with the toroidal cavity perforation; Seal valve seat 62 is set in the end of valve rod 61 buttress shaft sections and is flush-mounted in the embedded groove in spool housing buttress shaft section termination; Being tightly connected 63 is provided with sealing cone towards buttress shaft Duan Yiduan, the other end be provided be used for the valve body mounting hole in the socket cap of the Returnning spring 9 suits assembling of establishing, Returnning spring 9 residing mounting holes are provided with decompression gas circuit air outlet P1.
In addition, valve body is provided with the Stainless Steel Wire 16 that is connected usefulness with the outside joint of solenoid valve, mainly plays locking, locking effect.
As Fig. 3～shown in Figure 4, in comprising, establishes by pressure-regulating device the pressure regulation housing 10 of pressure regulation mounting hole and the look nut 11 that the outer end cooperates with its spinning thereof, the two ends of pressure regulation mounting hole are respectively equipped with first spring seat 12 and second spring seat 13, be folded with pressure adjusting spring 14 between two spring seats, center, the first spring seat exterior edge face is provided with and is used for first groove that cooperates with valve rod 61 setting-ins, center, the second spring seat exterior edge face is provided with second groove that is used for setting-in steel ball 15, and second spring seat and look nut 11 support assembling by steel ball 15 and close.
Working principle of the present utility model and process are following, and (the setting inlet pressure is 29MPa, the definite value decompression is 21MPa): the pressurized gas that feed 29MPa when the suction port of this integrated valve, enter in the gas circuit of valve body through filtrating equipment, one the tunnel directly realizes the output of 29MPa gas by Through solenoid valve 1, another road is through structure reduction valve as shown in Figure 4, the look nut 11 of reduction valve screws precompression pressure adjusting spring 14 and forms certain decrement, the throttle orifice that this moment, valve rod 61 and seal valve seat 62 formed has certain aperture, enter the annular inlet chamber chamber of spool housing and valve rod formation by the channel entrance P0 of pressure reducing air inlet pipeline when 29MPa gas, behind the throttle orifice that 29MPa gas forms by be tightly connected a sealing cone of 63 and seal valve seat 62 apertures, pressure is reduced to 21MPa, when outlet pressure 21MPa acts on power and Returnning spring 9 on the spool, when pressure adjusting spring 14 the power on the spool of acting on balances each other (influence of negligible friction), this moment, spool was in a kind of transient equiliblium, was the 21MPa gas that may command output meets the demands by 21MPa vacuum solenoid valve air outlet then.
When a certain reason causes that outlet pressure 21MPa raises, the power that suction pressure in the pressure reducing air inlet pipeline acts on the spool increases, spool moves towards the direction that makes throttle orifice be tending towards closing, the throttle orifice flow area diminishes, throttling action strengthens, thereby outlet pressure is reduced, so just make outlet pressure maintain near the fluctuation of pressure adjusting spring set pressure all the time, promptly outlet pressure maintains 21MPa and the influence of the rising variation that is not stressed.
When a certain reason causes that outlet pressure 21MPa reduces, the power that suction pressure in the pressure reducing air inlet pipeline acts on the spool reduces, spool moves towards the direction that makes throttle orifice be tending towards opening, it is big that the throttle orifice flow area becomes, throttling action weakens, thereby outlet pressure is increased, so just make outlet pressure maintain near the fluctuation of pressure adjusting spring set pressure all the time, promptly outlet pressure maintains 21MPa and the influence of the reduction variation that is not stressed.
When the outlet pressure of inlet pressure less than the setting of 21MPa(pressure adjusting spring) time, throttle orifice is opened fully, this moment, throttle orifice did not play throttling action, and outlet pressure is a little less than inlet pressure (pressure reduction is less than 1.72MPa), promptly when inlet pressure gas straight during less than the reduction valve set pressure.
Integrated valve of the present utility model is a domestic initiation, has realized the gas of system's source of the gas is divided into the purpose of different pressure piping output, can satisfy the demand to gas with various pressure.The level of integration height of this integrated valve, Placement is easy, is applicable to the system that level of integration is high; Unique modular construction design, product part replacement when safeguarding is simple, convenient and swift, has good maintainability; The definite value decompression is adjustable, is suitable for the different system requirement; Volume is little, in light weight, and compact structure is easy to use; The Safety performance height, reliable operation.
