Isakhiwo se-i-valve ye-diaphragmihluke kakhulu kuleyo yama-valve ajwayelekile.Kuwuhlobo olusha lwe-valve kanye nohlobo olukhethekile lwe-valve yokuvala.Ingxenye yayo yokuvula nokuvala i-diaphragm eyenziwe ngokuthambile Umgodi wangaphakathi wekhava kanye nengxenye yokushayela ihlukaniswe, futhi manje isetshenziswa kabanzi emikhakheni ehlukahlukene.Amavalvu e-diaphragm asetshenziswa kakhulu ahlanganisa amavalvu e-diaphragm anerabha, ama-diaphragm ane-fluorine-lined diaphragm, ama-diaphragm valves angenantambo, namavalve epulasitiki e-diaphragm.
I-valve ye-diaphragm ifakwe i-diaphragm eguquguqukayo noma i-diaphragm ehlanganisiwe emzimbeni we-valve kanye nesembozo se-valve, futhi ingxenye yayo evalayo iyithuluzi lokucindezela elixhunywe ne-diaphragm.Isihlalo se-valve singaba uhlobo lwe-weir noma uhlobo oluqondile.
Inzuzo ye-valve ye-diaphragm ukuthi indlela yokusebenza yayo ihlukaniswe ne-medium passage, engagcini nje ngokuqinisekisa ukuhlanzeka kwendawo yokusebenza, kodwa futhi ivimbela ukuthi kungenzeka ukuthi i-medium emgqeni ithinte izingxenye zokusebenza zendlela yokusebenza.Ukwengeza, alukho uphawu oluhlukile lwanoma yiluphi uhlobo oludingekayo esiqwini, ngaphandle njengesici sokuphepha ekulawuleni imidiya eyingozi.
Ku-valve ye-diaphragm, njengoba isisetshenziswa esisebenzayo sithintana kuphela ne-diaphragm kanye nomzimba we-valve, kokubili ongasebenzisa izinto ezihlukahlukene ezihlukahlukene, ngakho-ke i-valve ingakwazi ukulawula kahle izinhlobonhlobo zemidiya yokusebenza, elungele ikakhulukazi ukugqwala kwamakhemikhali noma izinhlayiya ezimisiwe.okuphakathi.
Izinga lokushisa elisebenzayo le-valve ye-diaphragm ngokuvamile lilinganiselwe izinto ezisetshenziselwa ulwelwesi lwe-diaphragm kanye ne-valve yomzimba, futhi izinga lokushisa layo lokusebenza liba ngu-50 kuya ku-175 °C.I-valve ye-diaphragm inesakhiwo esilula futhi yakhiwe izingxenye ezintathu eziyinhloko kuphela: umzimba we-valve, i-diaphragm kanye nokuhlanganiswa kwesembozo se-valve.I-valve kulula ukuyihlakaza nokulungisa ngokushesha, futhi ukushintshwa kwe-diaphragm kungenziwa esizeni nangesikhathi esifushane.
I-valve ye-diaphragm:
I-Lining material (ikhodi), izinga lokushisa lokusebenza (℃), i-medium efanelekile
Irabha eqinile (NR) -10â85℃ Hydrochloric acid, 30% sulfuric acid, 50% hydrofluoric acid, 80% phosphoric acid, alkali, usawoti, isixazululo sensimbi, i-sodium hydroxide, i-potassium hydroxide, i-neutral saline solution, 10% i-sodium hypochlorite , i-chlorine efudumele, i-ammonia, utshwala obuningi, ama-organic acid nama-aldehydes, njll.
Irabha Ethambile (BR) -10～85℃ Usimende, ubumba, umlotha we-cinder, umanyolo we-granular, uketshezi oluqinile olunokuqina okuqinile, ukugxila okuhlukahlukene kwamafinyila aminyene, njll.
Irabha ye-Fluorine (CR) -10～85℃ Amafutha ezilwane nemifino, okothambisa kanye nodaka olugqwalayo olunohlu olubanzi lwamanani e-pH.
Irabha ye-Butyl (HR) -10～120℃ I-Organic acid, i-alkali ne-hydroxide compounds, usawoti we-inorganic kanye nama-acids angenayo, i-elemental gas alcohols, i-aldehydes, i-ethers, i-ketone, njll.

Insimbi esakazwayo ngaphandle kolwelwesi Sebenzisa izinga lokushisa ngokwempahla yevalvu ye-diaphragm Engagqwali.
Insimbi engagqwali engafakwanga Imidiya egqwalayo.
Ukugcina ama-Diaphragm Valves
1. Ngaphambi kokufaka i-valve ye-diaphragm, hlola ngokucophelela ukuthi izimo zokusebenza zepayipi ziyahambisana yini nohlu olubekiwe lokusetshenziswa kwevalvu, futhi imbobo yangaphakathi kufanele ihlanzwe ukuze kuvinjelwe ukungcola ekubhajweni noma ukulimaza izingxenye zokuvala.
2. Ungapendi ingaphezulu lesendlalelo serabha yerabha kanye ne-diaphragm yerabha ngamafutha ukuze uvimbele irabha ekuvuvukeni futhi ithinte impilo yesevisi ye-valve ye-diaphragm.
3. Isondo lesandla noma indlela yokudlulisa ayivunyelwe ukuthi isetshenziselwe ukuphakamisa, futhi ukushayisana kwenqatshelwe ngokuphelele.
4. Uma usebenzisa i-valve ye-diaphragm ngesandla, i-lever eyisizayo akufanele isetshenziselwe ukuvimbela ukulimala ezingxenyeni zokushayela noma izingxenye zokuvala ngenxa ye-torque ngokweqile.
5. Ama-valve e-diaphragm kufanele agcinwe ekamelweni elomile nelingena umoya, futhi ukupakisha kuvinjelwe ngokuqinile.Zombili iziphetho ze-valve ye-diaphragm yesitoko kufanele zivalwe, futhi izingxenye zokuvula nokuvala kufanele zibe sesimweni esivuleke kancane.
Xazulula amaphutha avamile amavalvu e-diaphragm
1. Ukusebenza kwesondo lesandla akuguquguquki: ①Isiqu se-valve sigobile ②Intambo yonakele ①Buyisela isiqu se-valve ②Phatha intambo bese wengeza okokugcoba
2. I-valve ye-diaphragm yomoya ayikwazi ukuvuleka nokuvala ngokuzenzakalelayo: ①Umfutho womoya uphansi kakhulu ②Amandla asentwasahlobo makhulu kakhulu ③I-diaphragm yerabha yonakalisiwe ①Khulisa umfutho wokuphakelwa komoya ②Yehlisa amandla asentwasahlobo ③Shintsha i-diaphragm
3. Ukuvuza ekuxhumekeni phakathi kwe-valve yomzimba nebhonethi: ①Ibhawodi yokuxhuma iyaxega ②Isendlalelo senjoloba emzimbeni we-valve siphukile ①Qinisa ibhawodi lokuxhuma ②Buyisela indawo ye-valve
