Ivalve yebhabhathane ifanelekile kulawulo lokuhamba. Ngenxa yelahleko enkulu yoxinzelelo lweivelufa butterflykwipayipi, amandla epleyiti yebhabhathane xa ivaliwe kwaye imelana noxinzelelo lwemibhobho ephakathi kufuneka iqwalaselwe. Ukongeza, umda weqondo lokushisa elisebenzayo elinokumelana ne-valve ye-elastic seat kumaqondo obushushu aphezulu kufuneka uqwalaselwe. Ubude besakhiwo kunye nokuphakama ngokubanzi kwevalve yebhabhathane kuncinci, ivula kwaye ivale ngokukhawuleza, kwaye ineempawu ezilungileyo zokulawula ulwelo. Umgaqo-siseko wevalve yebhabhathane yeyona ifanelekileyo ukwenza iivalvu ezinobubanzi obukhulu. Xa i-valve butterfly iyadingeka ukuba isetyenziswe ukulawula ukuhamba, into ebaluleke kakhulu kukukhetha ngokuchanekileyo ubungakanani kunye nohlobo lwevalve yebhabhathane ukuze isebenze ngokufanelekileyo nangempumelelo.
Ngokuqhelekileyo, kwi-throttling, ulawulo olulawulayo kunye nodaka oluphakathi, kufuneka ukuba ubude besakhiwo bube bufutshane kwaye isantya sokuvula kunye nokuvala ngokukhawuleza (1/4 ukujika). Kwi-cutoff ephantsi yoxinzelelo (kunye nomehluko omncinci woxinzelelo), ivalve yebhabhathane iyacetyiswa.
Xa ujongene nokulawulwa kweendawo ezimbini, iziteshi ezinqamlekileyo, ingxolo ephantsi, i-cavitation kunye ne-vaporization phenomena, ukuvuza okuncinci kwi-atmosphere, kunye ne-media abrasive, i-valve butterfly ingakhethwa.
Xa usebenzisa iibhabhathane ivalve phantsi kweemeko ezikhethekileyo zokusebenza ezifana nokulawulwa kwe-throttling, iimfuno ezingqongqo zokutywinwa, ukunxiba kakhulu, ukushisa okuphantsi (cryogenic) kunye nezinye iimeko, intsimbi yokutywina eyenzelwe ngokukhethekileyo kunye nesixhobo sokulawula i-eccentricity emithathu okanye i-double eccentricity ezinikele i-butterfly valve kufuneka isetyenziswe.
I-valve ye-butterfly ifanelekile kwizicelo apho kufuneka ukutywinwa okupheleleyo, ukuvuza kwe-zero ngexesha lokuvavanya igesi kuyimfuneko, ubomi obude benkonzo bufunwa, kwaye ubushushu bokusebenza buvela kwi--10 degrees ukuya kwi-150 degrees. Isetyenziswa kumanzi acocekileyo, amanzi amdaka, amanzi olwandle, amanzi anetyuwa, umphunga, igesi yendalo, ukutya, amayeza, iimveliso zeoyile, iiasidi ezahlukeneyo, iziseko kunye neminye imibhobho.
Ivalve yebhabhathane etywiniweyo etywiniweyo ilungele ukuvuleka nokuvalwa kwendlela emibini kunye nolawulo lwemibhobho yokuphuma komoya nokususa uthuli. Isetyenziswa kakhulu kwimibhobho yegesi kunye nemijelo yamanzi yesinyithi, ishishini lokukhanya, amandla, kunye neenkqubo zepetrochemical.
I-valve ye-butterfly ye-metal-to-metal etywinwe kabini i-eccentric butterfly ifanelekile kwimibhobho eyahlukeneyo efana nokufudumeza kwedolophu, ukunikezelwa kwegesi, ukunikezelwa kwamanzi, njl., kwiigesi, i-oyile, i-acids, i-alkali, njl. Isetyenziswe njengesixhobo sokulawula kunye ne-throttling.
I-metal-to-metal face-sealed three eccentric butterfly valve ayinakusetyenziswa kuphela njengevalve yokulawula inkqubo yoxinzelelo olukhulu lwe-adsorption swing adsorption (PSA) izixhobo zokwahlula igesi, kodwa ikwasetyenziswa ngokubanzi kwimimandla efana nepetroleum, iikhemikhali zepetroli, iikhemikhali, isinyithi, kunye namandla. Yimveliso engenye elungileyo kwiivalvu zesango kunye neevalvu zeglowubhu.
