1. a kind of micro valve device, it is adaptable to a micro pressure power set, it is characterised in that it includes:

  • One valve sheet, with a valve opening, the valve sheet has the thickness between 0.1mm-0.3mm;

    One gas collection plate, with one first through hole, one second through hole, one first release chamber and a first outletChamber, and with a reference surface, the first outlet chamber has a convex portion structure, with to should valve sheetThe valve opening and set, favorably contradict the valve opening formation one prestressing effect, completely enclose the valve opening, the convex portion structureHighly it is higher than the reference surface of the gas collection plate, first through hole is connected with the first release chamber, and this secondThrough hole is connected with the first outlet chamber;

    AndOne exit plate, with one the 3rd through hole, one the 4th through hole, one second release chamber, a second outletChamber and at least a position limiting structure, and there is a convex portion structure through bore ends with a reference surface, the 3rd,The height of the convex portion structure is higher than the reference surface of the exit plate, and the favourable valve sheet quickly contradicts to form a prestressingEffect, completely encloses the 3rd through hole, and the 3rd through hole corresponds to first through hole of the gas collection plate, andBe connected with the second release chamber, the 4th through hole correspond to second through hole, and with the second outlet chamberRoom is connected, and an at least position limiting structure is arranged in the second pressure-releasing cavity room, the height of the position limiting structure betweenThere is a connection stream between 0.3mm-0.5mm, and between the second release chamber and the second outlet chamberRoad;

    Wherein, above-mentioned the gas collection plate, the valve sheet and the exit plate, which sequentially correspond to stack, sets positioning, the valvePiece is arranged between the gas collection plate and the exit plate, and the valve opening of the valve sheet is correspondingly arranged in second through holeAnd the 4th between through hole, gas is transmitted downwards from a minitype gas transmitting device of the micro pressure power setWhen in the micro valve device, entered the first release chamber by first through hole and second through hole and be somebody'"'"'s turn to doIn first outlet chamber, and import gas and progress collection pressure work in the 4th through hole is flowed into by the valve opening of the valve sheetIndustry, collects body of calming the anger and is more than and import gas, collects body of calming the anger from the 4th through hole towards the second outlet chamber, withMake the valve sheet displacement, and the valve opening of the valve sheet is resisted against the gas collection plate and is closed, and at least one spacing knotStructure Auxiliary support valve sheet, to prevent the valve sheet from collapsing, while collecting body of calming the anger in the second outlet chamber interior energyIt is flow to along connection runner in the second pressure-releasing cavity room, now in the valve sheet displacement in the second pressure-releasing cavity room, collection is calmed the angerPhysical efficiency is flowed out by the 3rd through hole, to carry out release operation.
