Ezisetshenzisweni zezimboni, ukukhethwa kwama-valve kudlala indima ebalulekile ekuqinisekiseni ukusebenza kahle kwesistimu nokuthembeka kwayo. I-valve ethandwa kakhulu eminyakeni yamuva nje i-valve ye-butterfly e-double flange triple eccentric. Lo mklamo we-valve omusha unikeza izinzuzo eziningi, okwenza kube ukukhetha kokuqala kuzo zonke izimboni ezahlukahlukene.

Okokuqala, umklamo oyingqayizivele wevalvu yebhamvane ephindwe kabili e-flange ephindwe kathathu e-eccentric uyenza ihluke kumavalvu ebhamvane endabuko. Umklamo "ophindwe kathathu" ubhekisela ezintweni ezintathu ezingavamile ezikhona esakhiweni sevalvu, okuhlanganisa ukungavamile kweshaft, ukungavamile kwe-cone centerline kanye nokungavamile kokuvala ubuso. Lo mklamo uhlinzeka ngesivalo esingenamoya ngisho nasezisetshenzisweni zokucindezela okuphezulu kanye nokushisa okuphezulu. Umklamo we-triple-eccentric uphinde unciphise ukuguguleka kwezingxenye zesivalo, okuholela empilweni yenkonzo ende kanye nezidingo zokunakekelwa ezincishisiwe.

Ngaphezu komklamo ohlanganisa izingxenye ezintathu, ukwakheka kwe-valve enezingqimba ezimbili kunikeza izinzuzo eziningana. Umklamo we-flange ezimbili kulula ukuwufaka nokuyinakekela ngoba i-valve ingafakwa kalula phakathi kwama-flange ngaphandle kwesidingo sokusekelwa okwengeziwe noma ukuhambisana. Lokhu kwenza i-valve ifaneleke kakhulu ekusetshenzisweni lapho isikhala silinganiselwe noma lapho kudingeka ukufakwa okusheshayo nokusebenzayo.

Enye inzuzo enkulu yevalvu ye-butterfly ye-double flange triple offset ukuthi iyakwazi ukuguquguquka. Lawa mavalvu afanelekela izinhlelo zokusebenza eziningi okuhlanganisa uwoyela negesi, i-petrochemical, ukukhiqizwa kukagesi kanye nokwelashwa kwamanzi. Ikhono layo lokusingatha ukucindezeleka okuphezulu kanye namazinga okushisa lenza kube ukukhetha okuthembekile ezindaweni zezimboni ezidinga kakhulu. Ngaphezu kwalokho, amakhono okuvala ivalvu angangenisi umoya ayenza ibe yindawo ekahle yokusebenzisa lapho ukuvimbela ukuvuza kubalulekile khona, njengalapho kuphathwa uketshezi olunobuthi noma oluyingozi.

Ngaphezu kwalokho, ivalvu ye-butterfly e-double flange triple eccentric inezici ezinhle kakhulu zokulawula ukugeleza. Umklamo wediski nesihlalo ohlelekile unciphisa ukumelana nokugeleza, kunciphisa ukwehla kwengcindezi futhi konga amandla. Lokhu kwenza leli valve libe yisinqumo esisebenzayo sokulawula ukugeleza kwamapayipi nezinhlelo zenqubo. Amandla okugoqa anembile evalvu ayenza ifaneleke ezinhlelweni ezidinga ukulawulwa okunembile kokugeleza.

Ngokuphathelene nokukhethwa kwezinto, amavalvu e-butterfly aphindwe kabili ane-flange e-eccentric angenziwa ngezinto ezahlukahlukene, okuhlanganisa insimbi yekhabhoni, insimbi engagqwali kanye nama-alloy angavamile. Lokhu kuvumela ukuhambisana nezinhlobo ezahlukene zoketshezi lwenqubo kanye nezimo zokusebenza. Ikhono lokwenza ngezifiso izinto ze-valve liqinisekisa ukuthi ziyahlangabezana nezidingo ezithile zezimboni ezahlukene kanye nezinhlelo zokusebenza.

Ngaphezu kwalokho, ivalvu ye-butterfly ye-double flange triple offset yenzelwe ukusebenza okuthembekile nokuhlala isikhathi eside. Ukwakhiwa okuqinile kanye nezinto ezisezingeni eliphezulu ezisetshenziswa enqubweni yokukhiqiza kuqinisekisa ukuthi ivalvu ingakwazi ukumelana nezimo zokusebenza ezinzima futhi inikeze ukusebenza okulinganayo kuyo yonke impilo yayo yokusebenza. Lokhu kuthembeka kubalulekile ekugcineni ubuqotho nokusebenza kahle kwezinqubo zezimboni.

Ngamafuphi, i-Double Flange Triple Offset Butterfly Valve inikeza izinzuzo eziningi ezenza ibe yimpahla ebalulekile ekusetshenzisweni kwezimboni. Umklamo wayo ohlanganisa izingxenye ezintathu, ukumiswa kwe-dual-flange, ukuguquguquka, amakhono okulawula ukugeleza, ukukhethwa kwezinto kanye nokuthembeka kwenza kube ukukhetha kokuqala kwezimboni ezifuna izixazululo zokulawula ukugeleza ezisebenzayo nezithembekile. Ngokuthuthuka okuqhubekayo kobuchwepheshe, i-double flange triple eccentric butterfly valve kulindeleke ukuthi idlale indima ebaluleke kakhulu ekuqinisekiseni ukusebenza kahle kwezinhlelo zezimboni.
