WZ Series Valve ya gede ya OS&Y leyi tshameke hi nsimbi
Nhlamuselo:
WZ Series Valve ya gede ya OS&Y leyi tshamaka hi nsimbi yi tirhisa gede ya nsimbi yo olova leyi nga na swirhendzevutani swa bronze ku tiyisisa ku pfariwa loku nga ngheniwiki hi mati. Valve ya gede ya OS&Y (Outside Screw and Yoke) yitirhisiwa ngopfu eka tisisiteme ta swifafazeri swo sirhelela ndzilo. Kuhambana lokukulu kusuka eka standard NRS (Non Rising Stem) gate valve hileswaku stem na stem nut swivekiwa ehandle ka miri wa valve. Leswi swiendla leswaku swi olova ku vona loko valve yi pfulekile kumbe yi pfariwile, tani hileswi kwalomu ka ku leha hinkwako ka nsinya ku vonakaka loko valve yi pfulekile, kasi nsinya aya ha vonaki loko valve yi pfariwile. Hiku angarhela leswi i xilaveko eka tinxaka leti ta tisisiteme ku tiyisisa vulawuri bya mahlo bya xihatla bya xiyimo xa sisiteme
Nxaxamelo wa swilo leswi tirhisiwaka:
| Swiphemu | Swilo |
| Miri | Nsimbi leyi hoxiweke,Nsimbi ya ductile |
| Disc | Nsimbi leyi hoxiweke,Nsimbi ya ductile |
| Nsinya | SS416,SS420,SS431 |
| Ring ya xitulu | Bronze/Brass |
| Bonnet | Nsimbi leyi hoxiweke,Nsimbi ya ductile |
| Nati ya nsinya | Bronze/Brass |
Xiphemu:
Wedge nut:Wedge nut yi endliwe hi copper alloy leyingana vuswikoti byo tola leswi nyikaka ku fambisana lokunene na stainless steel stem.
Wedge:Wedge yi endliwe kusuka eka ductile iron leyingana ti copper alloy face rings letinga machnined kuya eka fine surface finish kutiyisisa optimum contact seal na body seat rings.The wedge face rings yi endliwe kahle hi muchini naswona ti khomiwile swinene eka wedge.The guides eka wedge titiyisisa ku pfala loku fanaka kunga khathariseki ntshikelelo wale henhla.The wedge yina throught bore housing leyikulu ya nsinya leyi tiyisisaka leswaku kungari na stagnant mati kumbe thyaka swinga hlengeletana.Wedge yi sirheleriwa hiku hetiseka hi coating ya fusion bonded epoxy.
