Diaphragm twj, tseem hu ua cov twj tso kua mis tswj, yog thawj hom actuator. Lawv tau txais kev tswj cov teeb liab los ntawm lub chaw tswj kev tswj hwm thiab, los ntawm kev ua haujlwm fais fab, hloov cov kua dej ntws tawm. Lub luag haujlwm ntawm lub twj tso kua mis diaphragm hauv cov txheej txheem tswj yog kom tau txais kev tswj cov teeb liab los ntawm lub tshuab hluav taws xob lossis lub khoos phis tawj, hloov tus nqi ntws ntawm cov tswj nruab nrab, thiab tswj cov kev tswj tsis pub dhau qhov yuav tsum tau ua, yog li ua tiav automation ntawm cov txheej txheem ntau lawm.
Yog tias peb piv cov kev tswj hwm tsis siv neeg mus rau cov txheej txheem tswj kev tswj hwm, lub tshuab kuaj xyuas zoo li tib neeg lub qhov muag, lub chaw tswj hwm zoo li tib neeg lub hlwb, thiab tus actuator - lub twj tso kua mis diaphragm - zoo li tib neeg txhais tes thiab taw. Diaphragm twj yog qhov tseem ceeb rau kev tswj hwm thiab tswj cov kev txwv tshwj xeeb hauv cov txheej txheem, xws li kub, siab, ntws tus nqi, thiab qib kua.
Pneumatic diaphragm twj feem ntau siv tsib cov ntaub ntawv: yas, aluminium alloy, cam khwb cia hlau, stainless hlau, thiab Teflon. Cov twj siv hluav taws xob diaphragm siv plaub ntawm cov ntaub ntawv no: yas, aluminium alloy, cam khwb cia hlau, thiab stainless hlau. Lub diaphragm ntawm lub diaphragm twj tso kua mis yog ua los ntawm ntau yam ntaub ntawv xws li nitrile roj hmab, neoprene roj hmab, fluororubber, polytetrafluoroethylene (PTFE), thiab polytetrafluoroethylene (PTFE) nyob ntawm cov kua nruab nrab, thiab yog ntsia nyob rau hauv ntau yam tshwj xeeb daim ntawv thov mus twj tso kua mis ntau yam xov xwm kom tau raws li cov kev xav tau sib txawv.
