This high-pressure pneumatic switch valve utilizes at the same pressure, varying in size of the power that the spool cross section of gas to different size produces, relend help spring pre-tightening, electromagnet suction be used for quick closedown and open valve.As shown in Figure 1, after suction port 16 and high pressure gas holder link together, pressurized gas enter in valve through connection set by suction port 16, be divided into two branch roads afterwards, part gas enters into cavity of resorption 19 by lower channel 17, cavity of resorption 19 is by poppet valve core 21 with threaded hole, valve core case 14, and the space that vulcanized rubber circle 13 etc. surrounds, after gas enters into cavity of resorption, poppet valve core 21 with threaded hole is produced to the power (setting this power as F1) upwards of vertical valve core bar 29 cross section, another part gas enters into the side air guide channel 23 of valve body 10 through lower gas guide channel 18, epicoele 27 is entered into finally by upper gas guide channel 25, wherein epicoele 27 is by valve pocket 7, valve core rod 29, and valve gap 4 is closed and is formed, after pressurized gas enter into epicoele 27, valve core rod 29 is had to the downward active force (setting this power as F2) of its cross section vertical, because gas is at the acting surface 15 of cavity of resorption 19, its size equals the cross sectional area of the endoporus of valve core case 14, the cross section on valve core rod 29 top is deducted at the acting surface 26 of the epicoele endoporus cross section that is valve pocket 7 top, wherein go up acting surface and be a bit larger tham lower acting surface, and the active force of barometric pressure to valve core rod 29 is negligible, thus, valve core rod 29 is the transversal prone of vertical valve core bar 29 all the time with joint efforts under pressurized gas effect, and spring 6 herein valve gap 4 fixing tight after be in compressive state, to the active force downward (setting this power as F3) of valve core rod 29, therefore valve core rod 29 upper electromagnet 2 and and lower electromagnet 3 power-off time be downward all the time with joint efforts, like this, vulcanized rubber circle 13 on poppet valve core 21 with threaded hole is pressed on valve pocket base 14 tightly, such valve is in closed condition all the time.Open the lower gas guide channel 18 on valve body 10, side air guide channel 23, the opening end of upper gas guide channel 25 is all equipped with end socket, in order to avoid gas leak, it is larger than the aperture of valve base to be used for the aperture of the boss supporting valve pocket base 14 in valve body 10, valve pocket base 14 endoporus lower end rounding, to reduce frictional loss during gas flow, upper end end face chamfer, vulcanized rubber circle 13 is fully contacted with valve pocket base 14, Leakage Gas can not be made, simultaneously, valve pocket base 14 side has O RunddichtringO groove, to ensure that valve gas when closing can not spill from the gap between valve pocket base 14 and valve body 10.The design of valve pocket 7: the aperture on its top is identical with gas pilot hole 25 size, assemble time and coaxially install, bottom is identical with relief opening 12 with the size in the hole that relief opening 12 is connected, and it is coaxial when assembling, the endoporus requirement on machining accuracy of valve pocket 7 is higher, to ensure that two-way pressure difference is within the scope of needs, the seal groove that valve pocket is opened respectively with seal ring on valve pocket 5, seal ring 8 in valve pocket, valve pocket lower seal 9 is assembled and is used, the gas that on valve pocket wherein, seal ring 5 plays in airtight epicoele 27 can not spill from the gap between valve pocket 7 and valve gap 4, in close valve pocket, seal ring 8 is to prevent the gas at gas channeling hole 25 place from the air gap leakage between valve pocket and valve body, valve pocket lower seal 9 is to ensure that gas can not enter into lumen 22 from the gap between valve pocket 7 and valve body 10, lumen 22 is by valve pocket 7, valve core case 14, valve core rod 29, poppet valve core 21 with threaded hole is formed.Screw thread has been attacked respectively in valve core rod about 29 two ends, lower end is used for being connected with poppet valve core 21 with threaded hole, upper end is used for fixing lower electromagnet 3, the size of valve core rod 29 diameter everywhere needs strict to control to ensure and the cooperation of valve pocket and acting surface size, meanwhile, with valve core rod 29 with the use of valve core rod lower seal 11, on seal ring 24, valve core rod, seal ring 28 can ensure that no matter valve core rod can ensure that the gas in valve can not leak in static or dynamic process in valve core rod.Valve gap 4 and valve body 10 are connected by four bolts.Electromagnet stent 1 is fixed on valve gap by hexagon socket head cap screw, and the bolt hole that valve gap has is for Motionless electromagnetic retort stand 1, and cantilever tip has the counterbore for assembling hexagon socket head cap screw, and is used for fixing electromagnet 2.Have a pulling force (setting this power as F4) upwards to valve core rod after the energising of upper electromagnet 2, lower electromagnet 3, like this, what valve core rod was subject to makes a concerted effort for F1+F2+F3+F4, and | F4| is greater than | F1+F2+F3|, therefore resultant direction is upwards, thus upper electromagnet 2, lower electromagnet 3 electric after, what valve core rod 29 was subject to makes a concerted effort upwards, valve core rod 29 moves up, until two electromagnetic actuation contacts, spool moves, and valve is opened, gas enters lumen 22, and discharges from relief opening 12.
When not connecing source of the gas: valve is under spring 6 acts on, and valve is in closed condition all the time.
When connecting the power-off of source of the gas electromagnet: gas enters cavity of resorption 19 by inlet hole 16 part, pressure F1 is produced to valve core rod 29, a part enters lower gas guide channel 18, side air guide channel 23, upper gas guide channel 25, enter epicoele 27 again, pressure F2 is produced to valve core rod, and under spring force F3 effect, the power that valve core rod 29 is subject to is downward all the time, valve cuts out, and does not have gas to discharge.
Connect source of the gas electromagnet when obtaining electric: the power F4 that upper electromagnet 2, lower electromagnet 3 produce makes valve core rod 29 moves, until the adhesive completely of upper electromagnet 2, lower electromagnet 3, at this moment, valve is opened, and gas enters into lumen 22 by cavity of resorption 19 and discharges from relief opening 12.When electromagnet power-off, under the effect of F1+F2+F3, valve cuts out automatically.
