Ama-valve e-butterfly afanele ukulawulwa kokugeleza.Njengoba umfutho we-valve uvemvane epayipini mkhulu uma kuqhathaniswa, ocishe uphindwe kathathu kune-valve yesango, lapho kukhethwa i-valve uvemvane, ithonya lokulahlekelwa kwengcindezi ohlelweni lwamapayipi kufanele libhekwe ngokugcwele, kanye nokuqina kwepayipi eliphethe ipuleti uvemvane. ukucindezela okuphakathi lapho uvala kufanele kucatshangelwe.Ngaphezu kwalokho, umkhawulo wokushisa osebenzayo wezinto zokuhlala ezinwebekayo ekushiseni okuphezulu kufanele ucatshangelwe.

I-valve yovemvane inobude obuncane besakhiwo nobude bayo yonke, isivinini sokuvula nokuvala ngokushesha, nezici ezinhle zokulawula uketshezi.Isimiso sesakhiwo se-valve ye-butterfly ifaneleka kakhulu ekwenzeni ama-valve amakhulu.Lapho i-valve ye-butterfly idingeka ukulawula ukugeleza, into ebaluleke kakhulu ukukhetha kahle ubukhulu kanye nohlobo lwe-valve butterfly ukuze lusebenze kahle nangempumelelo.

Imvamisa, ekulawuleni ukudonsa nokulawula kanye nodaka oluphakathi, ubude besakhiwo esifushane kanye nesivinini sokuvula nokuvala (i-1/4 turn) kuyadingeka.I-valve yokusika ingcindezi ephansi (ingcindezi encane yokuhlukanisa), i-valve uvemvane iyanconywa.

I-valve ye-Butterfly ingakhethwa uma kulawulwa isikhundla esiphindwe kabili, isiteshi somhlaba esinentamo, umsindo ophansi, i-cavitation kanye ne-gasification, ukuvuza okuncane emkhathini kanye ne-abrasive medium.

Lapho i-valve uvemvane isetshenziswa ngaphansi kwezimo ezikhethekile zokusebenza, ezifana throttling regulation, izidingo esiqinile uphawu, noma ukugqoka kanzima, izinga lokushisa eliphansi (cryogenic) nezinye izimo zokusebenza, kubalulekile ukusebenzisa ekhethekile ezintathu eccentric noma double eccentric uvemvane valve nge ngokukhethekile. eklanyelwe uphawu lwensimbi kanye nedivaysi yokulawula.

I-valve butterfly ephakathi nendawo isebenza emanzini ahlanzekile, indle, amanzi olwandle, amanzi, umusi, igesi yemvelo, ukudla, imithi, imikhiqizo kawoyela, i-asidi ehlukahlukene kanye ne-alkali namanye amapayipi adinga ukuvalwa ngokuphelele, ukuvuza kokuhlolwa kwegesi okuyiziro, impilo yesevisi ephezulu kanye nezinga lokushisa lokusebenza. kokungu-10 ℃ ~ 150 ℃.

I-valve uvemvane oluthambile uphawu oluthambile ilungele ukuvulwa okubili, ukuvala nokulungiswa kwepayipi lokungena komoya kanye nokukhipha uthuli.Isetshenziswa kabanzi epayipini legesi kanye nesiteshi samanzi se-metallurgy, imboni yokukhanya, amandla kagesi kanye nohlelo lwe-petrochemical.

I-valve uvemvane oluyinsimbi ukuya ensimbi oluvalwe kabili lufanele ukushisisa kwasemadolobheni, ukuhlinzekwa kwegesi, ukuhlinzekwa kwamanzi kanye nenye igesi, uwoyela, isisekelo se-asidi namanye amapayipi njengesisetshenziswa esilawulayo nesiphundu.
