Kwintsimi yeevalve zoshishino, iibhola ze-valve ezifakwe kwi-trunnion zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza ngokufanelekileyo nokuthembekileyo kweenkqubo ezahlukeneyo. Ezi zixhobo zikhethekileyo ziyilelwe ukuba zimelane noxinzelelo oluphezulu, amaqondo obushushu agqithisileyo kunye neendawo ezinobungozi, zibenza zibaluleke kakhulu kuluhlu olubanzi lwezicelo kwi-oyile kunye negesi, i-petrochemical, ukuveliswa kwamandla kunye namanye amashishini.
Iivalvu zebhola ezifakwe kwi-Trunnion zizivalvu zebhola ezine-trunnion esisigxina esezantsi kunye ne-trunnion ephezulu eshukunyiswa ngokukhululekileyo. Olu luyilo luvumela ukuzinza okukhulu kunye nokulawula, ngakumbi kuxinzelelo oluphezulu kunye nezicelo eziphezulu zokushisa. Uyilo olufakwe kwi-trunnion lukwabonelela ngokutywinwa okukhuselekileyo, ukunciphisa umngcipheko wokuvuza kunye nokuqinisekisa ukuthembeka kwenkqubo.
Enye yeenzuzo eziphambili zeebhola zevalve ezifakwe kwi-trunnion kukukwazi kwabo ukuphatha iimeko ezinoxinzelelo oluphezulu. Kumashishini afana neoli kunye negesi, apho imisebenzi ihlala ibandakanya ukuthutha kunye nokuphatha ulwelo kwiingcinezelo eziphezulu kakhulu, iibhola ze-valve ezifakwe kwi-trunnion zibalulekile ekugcineni ukhuseleko lwenkqubo kunye nokusebenza kakuhle. Uyilo lwe-trunnion lusasaza uxinzelelo oluphezulu kwibhola yonke, ukunciphisa umngcipheko womonakalo kunye nokuqinisekisa ukusebenza okuthembekileyo.
Ukongezelela, i-trunnion-mounted ball design inokumelana namaqondo okushisa aphezulu, okwenza ukuba ilungele izicelo apho ukumelana nobushushu kubaluleke kakhulu. Nokuba kumaziko ombane apho umphunga kunye neegesi ezishushu zikhona, okanye kwiindawo zokusetyenzwa kweekhemikhali eziphatha imichiza eyonakalisayo, iibhola zevalve ezifakwe kwi-trunnion zibonelela nge-elasticity eyimfuneko ukuze kugcinwe ukusebenza kwazo phantsi kweemeko ezinzima ngolo hlobo.
Ukumelana nokukhula ngomnye umba obalulekileyo kwizicelo zemizi-mveliso, ngakumbi kwiindawo apho ulwelo oluphathwayo lwenza umhlwa ngokwendalo. Iibhola zevalvu ezifakwe kwi-Trunnion ziqhele ukwenziwa ngemathiriyeli efana nentsimbi engatyiwa, intsimbi exutywe nentsimbi, okanye ezinye iialloyi ezikwaziyo ukumelana nokudumba, ziqinisekisa ukuba ziyakwazi ukumelana neziphumo zezinto ezityiwayo kunye nokugcina ukusebenza kwazo ekuhambeni kwexesha. Oku kuxhathisa i-corrosion kubalulekile ekuthinteleni ukusilela kwenkqubo kunye nokuqinisekisa ukuba ixesha elide levalvu kwiindawo zokusebenza ezinzima.
Ngaphandle kokumelana noxinzelelo oluphezulu, amaqondo okushisa kunye neendawo ezinobungozi, iibhola ezifakwe kwi-trunnion zibonelela ngolawulo oluchanekileyo kunye nokutywinwa okuthembekileyo. Uyilo lwe-trunnion luvumela ukusebenza okugudileyo, okuchanekileyo, okwenza kube lula ukuvula nokuvala ivalve naphantsi kweemeko ezinzima. Eli nqanaba lolawulo libalulekile ekugcineni ukusebenza kakuhle kunye nokhuseleko lweenkqubo zoshishino.
Ukongezelela, isitywina esikhuselekileyo esinikezelwa yibhola efakwe kwi-trunnion ibalulekile ekuthinteleni ukuvuza kunye nokuqinisekisa ukunyaniseka kwenkqubo eyinxalenye yayo. Ubunakho bokutywina obuthembekileyo bezi zivalo bubalulekile ekuthinteleni ukuvuza kolwelo kunye neegesi, okubaluleke kakhulu kushishino apho nokuvuza okuncinci kunokuba neziphumo ezibi.
Ngokubanzi, iibhola zevalve ezifakwe kwi-trunnion zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza ngokukhuselekileyo nangokufanelekileyo kweenkqubo zemizi-mveliso. Ukukwazi kwabo ukumelana noxinzelelo oluphezulu, amaqondo obushushu agqithisileyo kunye neendawo ezitshabalalisayo, ezidityaniswa nolawulo oluchanekileyo kunye nokutywinwa okuthembekileyo, kubenza babe ngamacandelo ayimfuneko kwizicelo ezahlukeneyo. Ingaba kwishishini leoli kunye negesi, ukuveliswa kwamandla, ukusetyenzwa kweekhemikhali, okanye ezinye iindawo zoshishino, iibhola zevalve ezifakwe kwi-trunnion zibalulekile ekugcineni ukuthembeka kunye nokusebenza kweenkqubo ezibalulekileyo.
