Iivalve zebhabhathane zifanelekile kulawulo lokuhamba. Ekubeni ilahleko yoxinzelelo lwevalve yebhabhathane kumbhobho inkulu ngokwentelekiso, emalunga nokuphinda kathathu kwevalve yesango, xa ukhetha ivalve yebhabhathane, impembelelo yelahleko yoxinzelelo kwinkqubo yombhobho kufuneka iqwalaselwe ngokupheleleyo, kunye nokuqina kombhobho webhabhathane elithwele ipleyiti. uxinzelelo oluphakathi xa uvala kufuneka luqwalaselwe. Ukongeza, umda wokushisa osebenzayo wezinto zokuhlala ezilastiki kwiqondo lokushisa eliphezulu kufuneka uqwalaselwe.

Ivalve yebhabhathane inobude obuncinci besakhiwo kunye nokuphakama ngokubanzi, ukuvulwa okukhawulezayo kunye nesantya sokuvala, kunye neempawu 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.

Ngokuqhelekileyo, kwi-throttling kunye nokulawula ukulawula kunye nodaka oluphakathi, ubude obufutshane besakhiwo kunye nokuvula ngokukhawuleza kunye nesantya sokuvala (1 / 4 ukujika) kuyadingeka. Ivalve yokunqunyulwa koxinzelelo oluphantsi (uxinzelelo oluncinci oluhlukileyo), ivalve yebhabhathane iyacetyiswa.

I-valve ye-Butterfly inokukhethwa kwimeko yokulawula indawo ephindwe kabini, i-channel yomhlaba enentamo, ingxolo ephantsi, i-cavitation kunye ne-gasification, ukuvuza okuncinci kwi-atmosphere kunye ne-abrasive medium.

Xa ivalve yebhabhathane isetyenziswa phantsi kweemeko ezikhethekileyo zokusebenza, njengommiselo wokugobhoza, iimfuno ezingqongqo zokutywinwa, okanye ukunxiba okuqatha, ubushushu obuphantsi (cryogenic) kunye nezinye iimeko zokusebenza, kuyafuneka ukuba kusetyenziswe ivalve yebhabhathane eccentric okanye kabini eccentric ngokukodwa. eyenzelwe itywina lentsimbi kunye nesixhobo sokulawula.

Ivalve yebhabhathane ephakathi iyasebenza kumanzi amatsha, ugutyulo, amanzi olwandle, i-brine, umphunga, igesi yendalo, ukutya, iyeza, iimveliso zeoyile, iasidi eyohlukeneyo kunye nealkali kunye neminye imibhobho efuna ukutywinwa okupheleleyo, ukuvuza kovavanyo lwerhasi yero, ubomi benkonzo ephezulu kunye nobushushu bokusebenza. ye – 10 ℃ ~ 150 ℃.

Ivalve yebhabhathane ethambileyo eccentric ilungele ukuvuleka kwendlela ezimbini, ukuvala kunye nohlengahlengiso lombhobho wokuphuma komoya kunye nokususa uthuli. Isetyenziswa kakhulu kumbhobho wegesi kunye nomjelo wamanzi wesinyithi, ishishini lokukhanya, amandla ombane kunye nenkqubo yepetrochemical.

Intsimbi ukuya kwintsimbi etywinwe kabini i-eccentric butterfly valve ilungele ukufudumeza ezidolophini, unikezelo lwerhasi, unikezelo lwamanzi kunye nezinye igesi, i-oyile, isiseko se-asidi kunye neminye imibhobho njengesixhobo sokulawula kunye nokuthomalalisa.
