I-valve ye-diaphragm ingena esikhundleni sokuhlangana kwe-spool ngomzimba onomugqa omelana nokugqwala kanye ne-diaphragm emelana nokugqwala, esebenzisa ukunyakaza kwe-diaphragm ukuze ilawule. Okubalulekile kwe-valve ye-diaphragm eyenziwe ngensimbi ecijile, insimbi ecijile, noma insimbi engagqwali, futhi elayishwe ngezinto ezihlukahlukene ezimelana nokugqwala noma ezingagugi, irabha ye-diaphragm kanye ne-PTFE. I-diaphragm yolwelwesi inokumelana nokugqwala okuqinile, okulungele ukulawulwa kwemithombo yezindaba eyonakalisayo efana ne-asidi eqinile ne-alkali.
I-valve ye-diaphragm inesakhiwo esilula, ukumelana noketshezi oluncane, umthamo wokugeleza mkhulu kunezinye izinhlobo zama-valve anezincazelo ezifanayo; Akukho ukuvuza, kungasetshenziswa ukulungiswa kwe-viscosity ephezulu kanye nezinhlayiya ezimisiwe eziphakathi. I-diaphragm ihlukanisa i-medium ne-stem ekamelweni eliphezulu, ngakho-ke ayikho indlela yokupakisha engeke ivuze. Kodwa-ke, ngenxa yemikhawulo ye-diaphragm nezinto zokwenziwa kolayini, ukumelana nengcindezi nokumelana nezinga lokushisa kubi, ngokuvamile kulungele kuphela i-1.6MPa ingcindezi yegama kanye ne-150 ℃ ngezansi.
Isici sokugeleza se-valve ye-diaphragm siseduze nesici sokuvula ngokushesha, cishe esinomugqa ngaphambi kokushaywa kwe-60%, futhi izinga lokugeleza lishintshile kancane ngemva kuka-60%. Amavalvu e-pneumatic diaphragm angabuye afakwe amasiginali wempendulo, amadivaysi omkhawulo kanye nama-positioner, ukuze ahlangabezane nezidingo zokulawula okuzenzakalelayo, ukulawula uhlelo noma ukulawulwa kokugeleza. Isignali yempendulo yevalve ye-diaphragm ye-pneumatic kusetshenziswa ubuchwepheshe benzwa yokungathintwa. Umkhiqizo usebenzisa ifilimu propulsion cylinder, esikhundleni piston cylinder, ukuqeda piston indandatho kulula ukulimaza, okuholela ukuvuza futhi ayikwazi ukusunduza ukuvulwa valve nokuvala ukonakala. Lapho umthombo womoya wehluleka, usengakwazi ukusebenzisa isondo lesandla ukuze uvule futhi uvale i-valve.
