Mokhoa oa ho kenya pele le ka mor'a hore kakaretso e se ke ea beha valve ea karohano, feela maemong a motho ka mong, e ka sebelisoa. Haeba matla a mahareng a na le likaroloana tse tiileng, tse amang valve ea tšireletso e ke ke ea koaloa ka mor'a ho tloha, ho kenya valve ea heke e tiisitsoeng pele le ka morao, valve ea heke e lokela ho ba sebakeng se bulehileng ka ho feletseng, valve ea heke. le valve ea tšireletso e nang le valve ea ho hlahloba DN20 ka ho toba sepakapakeng.
Ha ho imoloha boka ba linotsi le mecha ea litaba tse ling ka mocheso kamoreng bakeng sa boemo bo tiileng, kapa fokotsa khatello ea gasification le e le hore leseli mokelikeli mahareng mocheso ka tlase 0 likhato Celsius, belofo polokeho hloka mocheso mouoane. Balofo ea tšireletso bakeng sa mecha ea phatlalatso e senyang, ho itšetlehile ka ho hanyetsa ha valve, nahana ka ho eketsa filimi e thibelang ho phatloha e thibelang ho phatloha ha valve e kenang. Hangata valve ea tšireletso ea khase e fanoa ka valve ea bypass ho ea ka boholo ba eona, e le mochine oa letsoho.
Lisebelisoa tse sireletsang tsa valve ea ho fokotsa khatello
Lisebelisoa tsa ho kenya li-valve tse fokotsang khatello hangata li na le mefuta e meraro. Li-gauge tsa khatello li kenngoa pele le ka mor'a valve e fokotsang ho thusa ho shebella khatello pele le ka mor'a valve. Ho na le sephahla se sireletsehileng se koaletsoeng ka ho feletseng ka mor'a valve ho thibela ho hlōleha ha sekhahla sa ho fokotsa khatello, valve ka mor'a hore khatello e fete khatello e tloaelehileng ha e qhoma, ho akarelletsa le valve ka mor'a tsamaiso.

Ts'ebetso ea kamehla ea fluorine lined anticorrosive valve
1, fluorine lined plastic valve medium mocheso: Mefuta e fapaneng ea k'hamphani ea rona ea li-valve tsa polasetiki tse nang le fluorine, tšebeliso ea polasetiki ea fluorine ke F46 (FEP), ts'ebeliso ea mocheso o mahareng o ke ke oa feta 150 ℃ (mocheso o mahareng o ka ba 150 ℃ ka nako e khuts'oane). nako, mocheso oa tšebeliso ea nako e telele o lokela ho laoloa ka 120 ℃), ho seng joalo, likaroloana tsa valve tse nang le F46 li bonolo ho nolofatsa, deformation, e leng se etsang hore valve e koalehe undead, ho lutla ho hoholo.
Haeba mocheso oa mochine o sebelisoang o le ka tlase ho 180 ℃ ka nako e khutšoanyane, 'me mocheso o ka tlase ho 150 ℃ ka nako e telele, ho ka khethoa mofuta o mong oa polasetiki ea fluorine; PFA, empa e kentsoeng ka polasetiki ea fluorine ea PFA e theko e boima ho feta e kentsoeng ka F46 ka theko.
2, ha ba na khatello e mpe. Fluorine lined polasetiki valve e lokela ho qoba tšebeliso ea khatello e mpe pompong, haeba ho na le khatello e mpe, ho bonolo ho etsa hore lesela la polasetiki le kentsoeng ka fluorine le phunyeletse ka ntle (drum out), le phunya, le lebisang ho buleheng ha valve le ho koala ho hlōleha. .
3, khatello, phapang ea khatello e lokela ho laoloa sebakeng se lumelletsoeng. Haholo-holo bellows seal lined fluorine polasetiki e laolang valve, globe valve. Hobane melumo e entsoe ka thepa ea tetrafluoric, phapang ea khatello le khatello e kholo, e ka lebisang habonolo ho phatloheng ha melumo.
Bellows seal lined fluorine polasetiki e laolang valve, tšebeliso ea khatello ea maemo, phapang ea khatello e kholo, e ka fetoloa ho PTFE packing seal.
