Gongyi Daewoo vacuum pressure release valve is placed in the reservoir Ash top, ash silo intake, exhaust overpressure and abnormal temperature changes, try to take care of ash storage repository without exceeding the limits of the positive and negative effects. Vacuum pressure release valve office principle: vacuum pressure release valve Construction: Vacuum pressure release valve from the flat cap, spring rings, activity ring, diaphragm retaining ring springs, retaining rings, valve cover, valve seats and other components. Valve rest position (tightly closed): When the ash silo or library pressure is maintained at a selected pressure value inside the valve, the valve cover to maintain the rest position. Because ash silo library or utility pressure force at the initiation of a flexible diaphragm (parts 4) Emergency contact with the top surface of the diaphragm into the valve seat (key 8), and therefore achieve tightly closed. 508 pressure vacuum release valve placed in the ash storage library affordable top of the ash silo intake, exhaust overpressure and abnormal temperature changes, try to take care of ash storage repository without exceeding limits the impact of positive and negative pressure is Ash must have to try to take care of one kind of device. Pressure release valve: When the ash silo library or a selected pressure increasing pressure to the valve when the pressure grapple clothing warehouse seat cover (part 7) weight, the bonnet lifted from the seat, while the pressure released, or until the ash silo library reduced pressure and the valve of the same value selected pressure, valve cap back to its normal position. www.gydayu.com material sealed pump www.hndyzg.com biaxial wetting mixer www.kuosanhanji.net molecular diffusion welding http://www.chuchenqidy.com/ baghouse http://www.dyqilishusong.com/ pneumatic conveying vacuum pressure release valve is mainly installed in the top of your library as an ash silo try to take care devices. Vacuum pressure release valve is mainly used top of your library release positive and negative pressure, can also be applied to other explosion-proof requirements of the occasion. Vacuum release valve: When the ash silo or large library pressure below atmospheric pressure, in the library or gray silo initiation vacuum, carefully empty value falls below the vacuum valve selected value, because of the large atmospheric pressure utility to the diaphragm, vacuum lifting ring to float position, this time the air into the silo or gray library until its value is less than the vacuum inside the selected value, the vacuum ring back to the normal position against the membrane. Release valve, vacuum release valve, vacuum pressure release valve, vacuum pressure release valve 508, professional production Ash try to take care devices, vacuum release valve, vacuum pressure release valve, vacuum pressure release valve 508.
