脈沖閥膜片是脈沖閥關鍵部件，是脈沖閥壽命的決定因素之一。
脈沖閥膜片材質：優質進口氟橡膠膜片。
脈沖閥膜片配件：不銹鋼墊片、鋁合金墊片、橡膠墊片、聚四氟乙烯墊片。
脈沖閥膜片材質是由一層特制的織物和附著在上面一層薄薄的彈性體組成，厚度通常在（0.2~1.1mm），膜片的壽命通常在數百萬次以上。
脈沖閥膜片工作原理：脈沖閥膜片是(shi)電(dian)(dian)(dian)磁(ci)脈(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)閥正常運(yun)行的(de)(de)關(guan)鍵(jian)所在(zai)，由脈(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)控制儀控制閥體內的(de)(de)膜(mo)片(pian)(pian)(pian)(pian)震動進街上脈(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)“沖(chong)(chong)(chong)量(liang)”噴(pen)吹(chui)清灰，膜(mo)片(pian)(pian)(pian)(pian)后(hou)控的(de)(de)面(mian)積(ji)大于(yu)前控的(de)(de)面(mian)積(ji)，氣壓(ya)(ya)作(zuo)用(yong)力(li)大。使膜(mo)片(pian)(pian)(pian)(pian)處在(zai)關(guan)鍵(jian)位(wei)置。脈(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)控制儀輸入電(dian)(dian)(dian)信號，使電(dian)(dian)(dian)磁(ci)先(xian)導頭吸合運(yun)性，打開卸(xie)荷孔。膜(mo)片(pian)(pian)(pian)(pian)后(hou)控的(de)(de)壓(ya)(ya)力(li)氣體迅速(su)排出。膜(mo)片(pian)(pian)(pian)(pian)前控的(de)(de)壓(ya)(ya)力(li)氣體將膜(mo)片(pian)(pian)(pian)(pian)抬起(qi)(qi)，打開電(dian)(dian)(dian)磁(ci)脈(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)閥通(tong)道(dao)進街上噴(pen)吹(chui)，電(dian)(dian)(dian)信號消(xiao)失，電(dian)(dian)(dian)磁(ci)先(xian)導頭的(de)(de)彈簧使動柱立即復位(wei)封閉卸(xie)荷孔，脈(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)閥膜(mo)片(pian)(pian)(pian)(pian)后(hou)控氣體壓(ya)(ya)力(li)和彈簧作(zuo)用(yong)力(li)使膜(mo)片(pian)(pian)(pian)(pian)關(guan)閉通(tong)道(dao)，電(dian)(dian)(dian)磁(ci)脈(mo)(mo)(mo)(mo)沖(chong)(chong)(chong)閥停止噴(pen)吹(chui)，膜(mo)片(pian)(pian)(pian)(pian)上的(de)(de)阻(zu)力(li)孔，當(dang)(dang)先(xian)導頭動柱抬起(qi)(qi)，氣體壓(ya)(ya)力(li)卸(xie)荷時(shi)，起(qi)(qi)到(dao)阻(zu)力(li)氣流的(de)(de)作(zuo)用(yong)，當(dang)(dang)卸(xie)荷封閉時(shi)，使壓(ya)(ya)力(li)氣體迅速(su)充(chong)滿到(dao)后(hou)腔，使膜(mo)片(pian)(pian)(pian)(pian)關(guan)閉通(tong)道(dao)，停止噴(pen)吹(chui)。
