Ivalve yebhabhathaneluhlobo lwevalvu esebenzisa idiskhi yokuvula kunye nelungu lokuvala ukubuyisela malunga ne-90 ° ukuvula, ukuvala okanye ukulungelelanisa ukuhamba kwe-medium.I-valve ye-Butterfly ayinayo nje isakhiwo esilula, ubungakanani obuncinci, ubunzima obulula, ukusetyenziswa kwezinto eziphantsi, ubungakanani obuncinci bokufakelwa, i-torque encinci yokuqhuba, ukusebenza okulula kunye nokukhawuleza, kodwa kunomsebenzi wokulawula ukuhamba kakuhle kunye neempawu zokuvala ngexesha elifanayo.Yenye yeentlobo zevalvu ezikhula ngokukhawuleza kule minyaka ilishumi idlulileyo.Izivalo zebhabhathane zisetyenziswa kakhulu kumashishini amaninzi.Iindidi kunye nobuninzi bokusetyenziswa kwayo zisakhula, kwaye ziphuhlisela ubushushu obuphezulu, uxinzelelo oluphezulu, ububanzi obukhulu, ukusebenza kokutywinwa okuphezulu, ubomi obude, iimpawu ezihle kakhulu zokulungelelanisa, kunye nokusebenza okuninzi kwevalve enye.Ukuthembeka kwayo kunye nezinye iimpawu zokusebenza zifikelele kwinqanaba eliphezulu.
Ngokusetyenziswa kwerabha yokwenziwa kweekhemikhali kwivalve yebhabhathane, ukusebenza kwevalve yebhabhathane kuye kwaphuculwa.Ekubeni irabha yokwenziwa ineempawu zokunganyangeki, ukukhukuliseka, ukuzinza komda, ukomelela okulungileyo, ukubunjwa lula, kunye neendleko eziphantsi, irabha yokwenziwa eneempawu ezahlukeneyo inokukhethwa ngokweemfuno ezahlukeneyo zokusetyenziswa ukuhlangabezana neemeko zokusebenza.iivalve butterfly.
Ngenxa yokuba i-polytetrafluoroethylene (PTFE) inokumelana nokugqwala okuqinileyo, ukusebenza okuzinzile, akulula ukuguga, i-coefficient ephantsi ye-friction, kulula ukwenza, kwaye izinzile ngobukhulu, kunye neempawu zayo ezibanzi zingaphuculwa ngokuzaliswa kunye nokongeza izinto ezifanelekileyo, okubangela amandla angcono ingxabano.Izinto zokutywinwa kwevalve yebhabhathane kunye ne-coefficient ephantsi iyoyisa imida yerabha eyenziweyo, ngoko ke izinto zepolymer ezimelwe yi-PTFE kunye nokuzaliswa kwayo kunye nezinto eziguqulweyo ziye zasetyenziswa ngokubanzi kwiivalvu zebhabhathane, ukwenzela ukuba kuphuculwe ukusebenza kweevalvu zebhabhathane.I-valve ye-butterfly eneqondo lokushisa elibanzi kunye noluhlu loxinzelelo, ukusebenza okuthembekileyo kokutywinwa kunye nobomi obude benkonzo buye iveliswa.
Ukuze kuhlangatyezwane neemfuno zesicelo sobushushu obuphezulu nobuphantsi, ukhukuliseko olunamandla, ubomi obude kunye nezinye izicelo zamashishini,ivalve yebhabhathane etywiniweyoziphuhliswe kakhulu.Ngokusetyenziswa kokumelana nobushushu obuphezulu, ukuxhathisa ubushushu obuphantsi, ukuxhathisa okuqinileyo, ukuxhathisa okuqinileyo kokhukuliseko, kunye nezixhobo eziphezulu zamandla ealloyi kwiivalvu zebhabhathane, iivalve zebhabhathane ezitywinwe ngentsimbi ziye zasetyenziswa kakhulu kwimimandla yemizi-mveliso efana nobushushu obuphezulu kunye nobushushu obuphantsi, bomelele. ukhukuliseko, kunye nobomi obude.
Xa ivalve yebhabhathane ivulwe ngokupheleleyo, inokumelana nokuhamba okuncinci.Xa ukuvulwa kuphakathi kwe-15 ° kunye ne-70 °, ulawulo olucacileyo lokuhamba lunokwenziwa, ngoko ke kwintsimi yokulungelelaniswa kwe-diameter enkulu, ukusetyenziswa kweevalve zebhabhathane kuxhaphake kakhulu.
Ngenxa yokuba ukuhamba kwepleyiti yebhabhathane kusula, iivalve ezininzi zebhabhathane zingasetyenziselwa imidiya kunye namasuntswana aqinileyo amisiweyo.Ngokuxhomekeke kumandla esitywina, ingasetyenziselwa i-powder kunye ne-granular media.
Iivalvu zebhabhathane zifanelekile kulawulo lokuhamba.Ngenxa yokuba ilahleko yoxinzelelo lwevalve yebhabhathane kumbhobho inkulu ngokwentelekiso, malunga nokuphindaphinda kathathuivalve yesango, xa ukhetha i-valve ye-butterfly, impembelelo yokulahlekelwa koxinzelelo lwenkqubo yombhobho kufuneka iqwalaselwe ngokupheleleyo, kwaye amandla e-butterfly plate ukumelana noxinzelelo lombhobho wepayipi kufuneka kuqwalaselwe xa ivaliwe.Ukongeza, ukunyinwa kobushushu bokusebenza kwezinto zokuhlala kwe-elastomeric kumaqondo obushushu aphakamileyo kufuneka kuqwalaselwe.
Iivalvu zebhabhathane zinobude obuncinci besakhiwo kunye nobude bubonke, ukuvulwa okukhawulezayo kunye nesantya sokuvala, kunye neempawu ezilungileyo zokulawula ulwelo.Umgaqo-siseko wevalve yebhabhathane yeyona ifanelekileyo ukwenza ivalve yobubanzi obukhulu.Xa i-valve butterfly iyadingeka ukuba isetyenziswe ukulawula ukuhamba, into ebaluleke kakhulu kukukhetha ngokuchanekileyo inkcazo kunye nohlobo lwevalve yebhabhathane ukuze isebenze ngokufanelekileyo nangempumelelo.
Ngokuqhelekileyo, kwi-throttling, ulawulo olulawulayo kunye nodaka oluphakathi, lufuneka ukuba lube nobude obufutshane besakhiwo, ukuvulwa ngokukhawuleza kunye nesantya sokuvala, ukunqunyulwa kwengcinezelo ephantsi (umlinganiselo omncinci woxinzelelo), kunye ne-valve butterfly inconywa.I-valve ye-Butterfly ingasetyenziselwa ukulungiswa kweendawo ezimbini, ukunciphisa ishaneli yobubanzi, ingxolo ephantsi, i-cavitation kunye ne-vaporization, inani elincinci lokuvuza emoyeni, kunye ne-abrasive medium.Ivalve yebhabhathane nayo ingasetyenziselwa uhlengahlengiso lwe-throttling phantsi kweemeko ezikhethekileyo zokusebenza, okanye isetyenziswe phantsi kweemeko zokusebenza ezinje ngokutywinwa okungqongqo, ukunxiba kakhulu, ubushushu obuphantsi (cryogenic), njl.
