Kukho iintlobo ezininziiivalve butterfly, kubandakanywa ukunqunyulwa ngokukhawuleza kunye nokulungiswa okuqhubekayo.Isetyenziswa kakhulu kwimibhobho yolwelo kunye negesi ephantsi yoxinzelelo olukhulu lobubanzi.Kufanelekile kwizihlandlo apho iimfuno zokulahlekelwa kwengcinezelo zingekho phezulu, ukulungelelaniswa kokuhamba kuyafuneka, kunye neemfuno zokuvula nokuvala zikhawuleza;ngokuqhelekileyo iqondo lokushisa lingaphantsi kwe-300 ℃ kwaye uxinzelelo lungaphantsi kwe-40 kg (iivalve zebhabhathane ngokubanzi zisebenzisa uxinzelelo oluphantsi, njengasekhaya. Bambalwa kakhulu abanokufikelela kwi-CL600), i-medium isetyenziswa ngokubanzi kumanzi kunye negesi, kwaye i-medium ayifuni; kunye ne-granular medium nayo ingasetyenziswa.
Njengevalve yebhabhathane etywiniweyo, yazisa uphuhliso olukhawulezayo emva kokuvela kwerabha eyenziweyo, ngoko ke luhlobo olutsha lwevalve yokuvala.Kwilizwe lam kude kube ngoo-1980, iivalvu zebhabhathane zazisetyenziswa ikakhulu kwiivalvu ezinoxinzelelo oluphantsi, kwaye isitulo sevalvu senziwe ngerabha eyenziweyo.Ngeminyaka yee-1990, ngenxa yotshintshiselwano olwandisiweyo namazwe angaphandle, iivalve zebhabhathane eziqinileyo (zentsimbi-seal) zaphuhliswa ngokukhawuleza.Okwangoku, kukho iifektri ezininzi zevalve ezinokuvelisa i-medium-pressure metal-sealed butterfly valves ngokuzinzileyo, okwenza indawo yokusetyenziswa kweevalve zebhabhathane ibe banzi.
Amajelo osasazo anokuthutha nokulawula ivalve yebhabhathane aquka amanzi, amanzi ajikisiweyo, amanzi ajikelezayo, ilindle, amanzi olwandle, umoya, igesi, igesi yendalo engamanzi, umgubo owomileyo, udaka, udaka lweziqhamo kunye nemixube eneziqina ezimisiweyo.
Iivalve zebhabhathane zifanelekile kulawulo lokuhamba.Ekubeni ilahleko yoxinzelelo lwevalve yebhabhathane kumbhobho inkulu ngokwentelekiso, imalunga nokuphinda kathathu kwevalve.Ngoko ke, xa ukhetha i-valve butterfly, impembelelo yokulahlekelwa kwengcinezelo yenkqubo yombhobho kufuneka iqwalaselwe ngokupheleleyo.Ukulahlekelwa kwengcinezelo ye-butterfly plate kufuneka kuqwalaselwe kwakhona xa i-butterfly plate ivaliwe.Ukuqina.Ukongeza, kuyafuneka ukuba kuthathelwe ingqalelo umda wobushushu obusebenzayo ukuba isitulo se-valve elastic inokumelana namaqondo obushushu aphezulu.Ubude besakhiwo kunye nokuphakama ngokubanzi kwevalve yebhabhathane zincinci, isantya sokuvula kunye nokuvala sikhawuleza, kwaye sineempawu ezilungileyo zokulawula ulwelo.Umgaqo wokwakhiwa kwevalve yebhabhathane yeyona ifanelekileyo ukwenza iivalve ezinobubanzi obukhulu.Xa i-valve butterfly iyadingeka ukulawula ukuhamba, into ebaluleke kakhulu kukukhetha ngokuchanekileyo ubungakanani kunye nohlobo lwevalve yebhabhathane ukuze isebenze ngokufanelekileyo nangempumelelo.
1. Ngokuqhelekileyo, kwi-throttling, ulawulo lokulawula kunye nodaka lodaka, isakhiwo sifunekayo ukuba sibe sifutshane ngobude kwaye sikhawuleze ekuvuleni nasekuvaleni isantya (1/4 revolution).Ukunqunyulwa koxinzelelo oluphantsi (umahluko omncinci woxinzelelo), ivalve yebhabhathane iyacetyiswa.
2. I-valve ye-butterfly ingasetyenziselwa xa ukulungiswa kweendawo ezimbini, ishaneli yokunciphisa, ingxolo ephantsi, i-cavitation kunye ne-gasification phenomenon, inani elincinci lokuvuza kwi-atmosphere, kunye ne-media abrasive.
3. Xa i-valve butterfly isetyenziswe phantsi kweemeko ezikhethekileyo ezifana nokulungelelaniswa kwe-throttling, okanye iimfuno zokutywinwa ngokungqongqo, okanye i-abrasion enzima, ukushisa okuphantsi (cryogenic) kunye nezinye iimeko zokusebenza, kuyimfuneko ukusebenzisa isitywina sesinyithi esilungiselelwe ngokukhethekileyo nge-eccentric kathathu okanye Isixhobo sohlengahlengiso kabini eccentric Ivalve yebhabhathane ezinikeleyo emhlabeni.
4. Ivalve yebhabhathane ephakathi ilungele amanzi amatsha, ugutyulo, amanzi olwandle, amanzi etyuwa, umphunga, igesi yendalo, ukutya, amayeza, kunye neoyile ezifuna ukutywinwa okupheleleyo, ukuvuza kovavanyo lwerhasi zero, ubomi benkonzo ephezulu, kunye nobushushu bokusebenza - 10℃~150℃.Kwaye ezahlukeneyo acid kunye alkali kunye neminye imibhobho.
5. Ivalve yebhabhathane ye-eccentric etywiniweyo ethambileyo ifanelekile ekuvuleni nasekuvaleni ngeendlela ezimbini kunye nohlengahlengiso lwemibhobho yokuphuma komoya kunye nokususa uthuli, kwaye isetyenziswa kakhulu kwimibhobho yegesi kunye neendlela zamanzi kwi-metallurgy, ishishini lokukhanya, amandla ombane, kunye neenkqubo zepetrochemical.
6. Ivalve ye-metal-to-metal yokutywina ibhabhathane ye-eccentric ilungele ukufudumeza ezidolophini, unikezelo lwerhasi, unikezelo lwamanzi kunye neminye imibhobho yerhasi, i-oyile, iasidi kunye nealkali, njengesixhobo sokulawula kunye nokuthomalalisa.
7. Ukongeza ekusetyenzisweni njenge-adsorption enkulu yoxinzelelo lwe-swing adsorption (PSA) igesi yokwahlula i-valve yokulawula inkqubo, i-valve ye-Jinyong yesinyithi etywinwe kathathu i-eccentric butterfly valve ingasetyenziswa ngokubanzi kwi-petroleum, i-petrochemical, ikhemikhali, isinyithi, amandla ombane kunye eminye imimandla.Yivalve yesango kunye nevalve yeglowubhu.Imveliso engenye elungileyo.
