Valavu ya diaphragm imalowa m'malo mwa spool ndi thupi lokhala ndi mzere wosagwirizana ndi dzimbiri komanso diaphragm yolimbana ndi dzimbiri, yomwe imagwiritsa ntchito kayendedwe ka diaphragm kuti iziwongolera. Mavavu a diaphragm amapangidwa ndi chitsulo chosungunula, chitsulo chosapanga dzimbiri, kapena chitsulo chosapanga dzimbiri, chokhala ndi zinthu zosiyanasiyana zosagwira dzimbiri kapena zosavala, mphira wa diaphragm ndi PTFE. The diaphragm of the lining is a strong corrosion resistance, yomwe ili yoyenera kuwongolera njira zowononga zowonongeka monga asidi amphamvu ndi alkali.
Valavu ya diaphragm ili ndi dongosolo losavuta, kukana kwamadzimadzi kakang'ono, mphamvu yothamanga ndi yayikulu kuposa mitundu ina ya ma valve omwe ali ndi zofanana; No kutayikira, angagwiritsidwe ntchito kusintha kwa mkulu mamasukidwe akayendedwe ndi inaimitsidwa particles sing'anga. The diaphragm imalekanitsa sing'anga kuchokera ku tsinde lapamwamba chipinda, kotero palibe chotengera cholongedza chomwe sichingatayike. Komabe, chifukwa cha malire a diaphragm ndi zida zomangira, kukana kukakamiza komanso kukana kutentha kumakhala kocheperako, nthawi zambiri kumakhala koyenera kukakamiza mwadzina kwa 1.6MPa ndi 150 ℃ pansipa.
Mayendedwe a valve ya diaphragm ali pafupi ndi mawonekedwe otsegula mofulumira, omwe amakhala pafupifupi mzere pamaso pa 60% sitiroko, ndipo kuthamanga kwake kumasinthidwa pang'ono pambuyo pa 60%. Ma valve a pneumatic diaphragm amathanso kukhala ndi zizindikiro zowonetsera, zochepetsera ndi zoikapo malo, kuti akwaniritse zofunikira zodziwongolera zokha, kuwongolera pulogalamu kapena kuyendetsa bwino. Chizindikiro cha ma valve a pneumatic diaphragm pogwiritsa ntchito ukadaulo wosalumikizana. Chogulitsacho chimagwiritsa ntchito silinda yoyendetsa filimu, m'malo mwa silinda ya pisitoni, kuti athetse mphete ya pistoni ndiyosavuta kuwononga, zomwe zimapangitsa kutayikira ndipo sangathe kukankhira zovuta zotsegula ndi kutseka kwa valve. Pamene mpweya gwero kulephera, akadali ntchito gudumu dzanja kutsegula ndi kutseka valavu.
