Ukuqaliswa kwevalve yebhabhathane

Ivalve yebhabhathane, nekwaziwa ngokuba yivalve eneflap, yivalve elula elawulayo, enokuthi isetyenziselwe ukulawula ukucima kombhobho ophakathi woxinzelelo oluphantsi. Ivalve yebhabhathane luhlobo lwesivalo esinendawo yokuvala (idiski okanye ipleyiti yebhabhathane) iyidiski kwaye ijikeleza iaxis yevalve ukuvula nokuvala. Idlala kakhulu indima yokunqunyulwa kunye ne-throttling kumbhobho. Inxalenye yokuvula kunye nokuvala i-valve ye-butterfly yi-disc-shaped butterfly plate, ejikelezayo kwi-axis yayo kumzimba wevalve, ukuze kufezekiswe injongo yokuvula nokuvala okanye ukulungiswa. Ivalve yebhabhathane iyasebenza kumbhobho ogqithisa ulwelo olwahlukeneyo nolungadlekiyo kwinkqubo yobunjineli bejenereyitha, irhasi, irhasi yendalo, irhasi yepetroleum engamanzi, igesi yesixeko, umoya obandayo noshushu, ukunyibilikiswa kweekhemikhali, ukwenziwa kombane kunye nokhuseleko lokusingqongileyo. Isetyenziselwa ukulawula kunye nokunqumla ukuhamba kwe-medium. Ukusetyenziswa kwevalve yebhabhathane Ivalve yebhabhathane ifanelekile kulawulo lokuhamba. Njengoko ilahleko yoxinzelelo lwevalve yebhabhathane kumbhobho inkulu ngokwentelekiso, emalunga namaxesha amathathu evalve 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. Ukongezelela, umda wokushisa osebenzayo wezinto zokuhlala ezizinzileyo kwiqondo lokushisa eliphezulu kufuneka ziqwalaselwe. Ivalve yebhabhathane ineengenelo zobude besakhiwo esincinci kunye nokuphakama ngokubanzi, ukuvulwa ngokukhawuleza kunye nesantya sokuvala, kunye neempawu ezilungileyo zokulawula ulwelo. Umgaqo-siseko wevalve yebhabhathane yeyona ifanelekileyo ukwenza ivalve enkulu yodayamitha. Xa i-valve butterfly iyadingeka ukulawula ukuhamba, into ebaluleke kakhulu kukukhetha ubungakanani kunye nohlobo lwevalve yebhabhathane ngokufanelekileyo nangempumelelo. Ngokuqhelekileyo, kwi-throttling, ulawulo olulawulayo kunye nodaka oluphakathi, ubude obufutshane besakhiwo kunye nokuvulwa ngokukhawuleza kunye nesantya sokuvala (1 / 4R) siyafuneka. Ukunqunyulwa koxinzelelo oluphantsi (umahluko ophantsi woxinzelelo), ivalve yebhabhathane iyacetyiswa. I-valve ye-Butterfly ingasetyenziselwa ukulungiswa kwendawo ephindwe kabini, ishaneli yentamo, ingxolo ephantsi, i-cavitation kunye ne-gasification, inani elincinci lokuvuza emoyeni kunye ne-abrasive medium. Xa usebenzisa i-valve yebhabhathane phantsi kweemeko ezikhethekileyo zokusebenza, ezifana nommiselo we-throttling, imfuneko yokutywinwa engqongqo, ukunxitywa okukhulu, ubushushu obuphantsi (cryogenic), njl., i-valve ekhethekileyo ye-tri eccentric okanye i-Bi eccentric butterfly enesixhobo esikhethekileyo sokutywinwa kwesinyithi siyafuneka. Ivalve yebhabhathane ephakathi ilungele amanzi amatsha, ugutyulo, amanzi olwandle, i-brine, umphunga, igesi yendalo, ukutya, amayeza, ioyile, iiasidi ezahlukeneyo kunye neziseko kunye neminye imibhobho efuna ukutywinwa okupheleleyo, ukuvuza kwe-zero kuvavanyo lwegesi, ubomi benkonzo ephezulu. kunye nobushushu bokusebenza - 10 ~ 150 ℃. Ivalve yebhabhathane ethambileyo eccentric ilungele ukuvuleka nokuvala indlela emibini 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 yentsimbi etywinwe kabini eccentric ibhabhathane ivelufa ilungele ukufudumeza ezidolophini, ubonelelo ngomphunga, ubonelelo lwamanzi kunye negesi, i-oyile, iasidi kunye nemibhobho yealkali, njengokulawula kunye nezixhobo zokunqanda. Intsimbi ukuya kwintsimbi ubuso etywiniweyo kathathu eccentric butterfly valve ingasetyenziswa ngokubanzi kwipetroleum, petrochemical, chemical, metallurgy, amandla ombane kunye neminye imimandla ngaphandle kokusetyenziswa njengevalve yolawulo lwenkqubo yeyunithi enkulu yokwahlula igesi yePSA. Yindawo efanelekileyo yevalve yesango kunye nevalve yokumisa. Umgaqo wokukhetha wevalve yebhabhathane 1. Xa kuthelekiswa nevalve yesango, ivalve yebhabhathane inolahleko olukhulu loxinzelelo, ngoko ilungele inkqubo yemibhobho eneemfuno zolahleko loxinzelelo lwax 2. Njengoko ivalve yebhabhathane ingasetyenziselwa ukulawula ukuhamba, ifanelekile ukuba ikhethwe. kumbhobho odinga umgaqo wokuqukuqela 3. Ngenxa yokuthintelwa kolwakhiwo lwevalvu yebhabhathane kunye nemathiriyeli yokutywina, ayifanelekanga kubushushu obuphezulu kunye nenkqubo yemibhobho yoxinzelelo oluphezulu. Ngokubanzi, ubushushu bokusebenza bungaphantsi kwe-300 ℃ kwaye uxinzelelo lwegama lungaphantsi kwe-PN40. 4. Ngenxa yokuba ubude besakhiwo sevalve yebhabhathane bufutshane, kwaye bunokwenziwa kwidayamitha enkulu, ngoko ke kwimeko yeemfuno zobude besakhiwo esifutshane okanye ivalve enkulu yedayamitha (efana ne-DN 1000), ivalve yebhabhathane kufuneka ikhethwe. 5. Ngenxa yokuba i-valve ye-butterfly inokuvulwa okanye ivalwe kuphela ngokujikeleza kwe-90 °, ifanelekile ukusebenzisa i-valve butterfly kwintsimi apho iimfuno zokuvula nokuvala zikhawuleza.
