My factory production well ventilated reed valve uses the steel platewelding manufacture, has the structure size short, the weight islight, characteristic and so on installment convenience. This valvedriving moment is small, opens shuts nimbly, ease of operation. On thevalve body establishes 油密封 the elastic ring, seals vice- betweendoes not have the gap, divulging rate is obviously small. Clearancefor expansion between of the butterfly board and the valve body isbig, can effectively prevent because hotly to rise the deactivationphenomenon which the contraction creates. This valve may provide themany kinds of drive, like hand gear, worm gearing, pneumatics,electrically operated installment. Ventilates the reed valve widely touse in to govern the gold, industry pipeline and so on Shi Hua,electric power, building materials, mine, is mad the control or thecontrol action to the medium gas.

2.Use and characteristic

The circular 百叶 type reed valve and the electrically operatedelectricity implementing agency necessary widely applies to thebuilding materials, governs production process and so on the gold,mine, electric power, can the automatic control or in the hand controladjustment pipeline using of the medium current capacity. Thebutterfly petal uses 百叶 many 轴体 structures, the liquid even,opens shuts the strength evenly, movement keen, the performance isreliable.
