Amavalvu we-butterfly zilungele amapayipi athutha iindaba ezihlukahlukeneko ezigugako nezingaguliko eenhlelweni zobunjiniyela ezifana negesi yamalahle, igesi yemvelo, igesi yephethroliyamu, igesi yedorobha, umoya otjhisako nobandako, ukuncibilikisa ngamakhemikhali, ukukhiqizwa kwamandla nokuvikelwa kwebhoduluko, begodu zisetjenziselwa ukulungisa nokuvala ukugeleza kwemidiya.
Amavalvu we-butterfly zilungele ukulawulwa kokugeleza. Ngombana ukulahlekelwa mfutho we-butterfly valve ngaphakathi kwepayipi kukhulu, okuphindwe kathathu kune-gate valve, lokha nawukhetha i-butterfly valve, umthelela wehlelo lephayiphi ngokulahlekelwa mfutho kufanele uqalwe ngokuzeleko, begodu ukuqina kwepuleti ye-butterfly ukujamelana nomfutho wephayiphu kufanele kuqalwe lokha nayivaliweko. ubulili. Ukungezelela, ukulinganiselwa kwamazinga womtjhiso wokusebenza wezinto zesihlalo se-elastomeric emazingeni womtjhiso aphakemeko kufanele kuqalwe.
Ubude besakhiwo nokuphakama okuphelelekoivalvu yevivanezincani, ijubane lokuvula nokuvala lirhaba, begodu lineemfanelo ezihle zokulawula amanzi. Umthetho wokwakheka kwe-valve ye-butterfly ufaneleke khulu ekwenzeni ama-valve amakhulu. Lokhaivalvu yevivane kuyatlhogeka bona isetjenziselwe ukulawula ukugeleza, into eqakatheke khulu kukhetha kuhle ubukhulu nomhlobo wevalvu ye-butterfly ukwenzela bona isebenze kuhle begodu ngepumelelo.
Ngokuvamileko, ekuthomeni, ukulawula ukulawula nodaka, ubude besakhiwo esifitjhani kanye nejubane lokuvula nokuvala elirhabako (1/4r) kuyatlhogeka. Ukunqunywa kwegandelelo eliphasi (umfutho omncani womehluko), ivalvu ye-butterfly iyaphakanyiswa.Ivalvu ye-butterflyingasetjenziswa ekulungiseni iindawo ezimbili, umzila omncani, umsindo omncani, ukuvuleka nokutjhuguluka kwegesi, ukuvuza okuncani emkhathini, kanye nendawo yokukhuhla.
I-concentric ivalvu yevivane ilungele amanzi afretjhi, indle, amanzi welwandle, amanzi anetswayi, umtjhiso, irhasi yemvelo, ukudla, imithi, amafutha kanye namapayipi ahlukahlukeneko we-Acid-base namanye.
Ivalvu ye-butterfly evalwe ngokuthambileko ilungele ukuvulwa nokuvala ngeendlela ezimbili nokulungiswa kwamapayipi wokungenisa umoya nokususa ithuli begodu isetjenziswa khulu emaphayiphini wegesi kanye neendlela zamanzi ze-metallurgy, ibubulo elilula, amandla kagesi, kanye neenhlelo ze-petrochemical.
