Kwimisebenzi yemizi-mveliso, ukukhetha iivalvu kudlala indima ebalulekileyo ekuqinisekiseni ukusebenza kakuhle kwenkqubo kunye nokuthembeka kwayo. Eyona valve idumileyo kwiminyaka yakutshanje yivalvu yebhabhathane ephindwe kabini ene-flange ephindwe kathathu. Olu yilo lwevalvu lutsha lubonelela ngeenzuzo ezahlukeneyo, nto leyo eyenza ukuba ibe lolona khetho luphambili kwiindidi ezahlukeneyo zemizi-mveliso.

Okokuqala, uyilo olulodwa lwevalvu yebhabhathane ephindwe kabini ene-flange ephindwe kathathu yenza yahluke kwiivalvu zebhabhathane zemveli. Uyilo "oluphindwe kathathu" lubhekisa kwizinto ezintathu ezingaqhelekanga ezikhoyo kwisakhiwo sevalvu, kubandakanya ukungafani kweshaft, ukungafani kwe-cone centerline kunye nokungafani komphezulu wokutywina. Olu yilo lubonelela ngetywina elingenasici nokuba kuxinzelelo oluphezulu kunye nokusetyenziswa kobushushu obuphezulu. Uyilo oluphindwe kathathu lukwanciphisa ukuguguleka kwezinto zesitywina, nto leyo ebangela ubomi benkonzo ende kunye neemfuno zokugcinwa ezinciphileyo.

Ukongeza kuyilo olunemiphetho emithathu, ulwakhiwo lwevalvu olunemiphetho emibini lubonelela ngeenzuzo ezininzi. Uyilo lwemiphetho emibini kulula ukuyifaka nokuyigcina ikwimeko entle kuba ivalvu inokufakwa lula phakathi kweeflanges ngaphandle kwesidingo senkxaso eyongezelelweyo okanye ulungelelwaniso. Oku kwenza ivalvu ilungele ukusetyenziswa apho indawo incinci okanye apho kufuneka ufakelo olukhawulezileyo nolusebenzayo.

Enye inzuzo enkulu yevalvu yebhabhathane ye-double flange triple offset kukuba iyakwazi ukuguquguquka. Ezi valve zifanelekile kwiintlobo ngeentlobo zezicelo kuquka ioyile negesi, i-petrochemical, ukuveliswa kombane kunye nonyango lwamanzi. Ukukwazi kwayo ukujongana noxinzelelo oluphezulu kunye namaqondo obushushu kwenza ukuba ibe lukhetho oluthembekileyo kwiindawo zoshishino ezifuna amandla. Ukongeza, amandla okuvala ivalvu angangeni moya ayenza ifaneleke kwiizicelo apho ukuthintela ukuvuza kubalulekile, njengaxa iphatha ulwelo olunetyhefu okanye oluyingozi.

Ukongeza, ivalvu yebhabhathane e-double flange triple eccentric ineempawu ezibalaseleyo zokulawula ukuhamba kwamanzi. Uyilo lwediski kunye nesihlalo olucwangcisiweyo lunciphisa ukumelana nokuhamba kwamanzi, lunciphisa ukuhla koxinzelelo kwaye longa amandla. Oku kwenza le valve ibe lukhetho olusebenzayo lokulawula ukuhamba kwamanzi kwimibhobho nakwiinkqubo zenkqubo. Amandla okuthomalalisa achanekileyo evalvu ayenza ifaneleke kwizicelo ezifuna ulawulo oluchanekileyo lokuhamba kwamanzi.

Ngokuphathelele ukhetho lwezinto, iivalvu zebhabhathane ezi-double flange triple eccentric zinokwenziwa ngezinto ezahlukeneyo, kuquka intsimbi yekhabhoni, intsimbi engatyiwayo kunye nee-alloys ezinqabileyo. Oku kuvumela ukuhambelana neentlobo ngeentlobo zolwelo lwenkqubo kunye neemeko zokusebenza. Ukukwazi ukwenza ngokwezifiso izixhobo zevalvu kuqinisekisa ukuba ziyahlangabezana neemfuno ezithile zamashishini kunye nezicelo ezahlukeneyo.

Ukongeza, ivalvu yebhabhathane ye-double flange triple offset yenzelwe ukusebenza okuthembekileyo nokuhlala ixesha elide. Ulwakhiwo oluqinileyo kunye nezixhobo ezisemgangathweni ophezulu ezisetyenziswa kwinkqubo yokuvelisa ziqinisekisa ukuba ivalvu inokumelana neemeko ezinzima zokusebenza kwaye ibonelele ngokusebenza rhoqo kulo lonke ixesha layo lokusebenza. Oku kuthembeka kubalulekile ekugcineni ukuthembeka nokusebenza kakuhle kweenkqubo zoshishino.

Ngamafutshane, iDouble Flange Triple Offset Butterfly Valve inikezela ngeenzuzo ezahlukeneyo ezenza ukuba ibe yimpahla exabisekileyo kwizicelo zoshishino. Uyilo lwayo olunemiqolo emithathu, ulungelelwaniso lwemiqolo emibini, ukuguquguquka, amandla okulawula ukuhamba kwamanzi, ukukhethwa kwezinto kunye nokuthembeka kwenza ukuba ibe lukhetho lokuqala kumashishini afuna izisombululo zokulawula ukuhamba kwamanzi ezisebenzayo nezithembekileyo. Ngokuqhubeka kweteknoloji, ivalvu yebhabhathane eneemiqolo emithathu eenxantathu kulindeleke ukuba idlale indima ebaluleke ngakumbi ekuqinisekiseni ukusebenza kakuhle kweenkqubo zoshishino.
