ntalisyo yakusala chibelesyo cha magesi cha butterfly valve

A. Nguzu zyakubeleka

Nguzu zyakubeleka nchintu chipati loko mukusalavvalavu ya butterflychintu chibelesya magesi. Nguzu zyakuzwa zyamagesi zyeelede kuba 1.2~1.5 ziindi zyanguzu zyakubeleka zyavvalavu ya butterfly.

B. Nguzu zyakubeleka

Kuli zibeela zyobile zipati zyavvalavu ya butterfly chintu chibelesya magesi: chimwi tachikwe chintu chakusunka, mpawo nguzu zyakuzungaanya zilazwa biyo; aimwi ilijisi bbazu lyakusunka, mpawo nguzu zyakuzwa zilasandulwa kuba ntalisyo yakuzwa kwiinda muchikozyano cha valve mupuleti yakusunka.

C. Mweelwe wamajokoloka aamugoti wakuzwa

Mweelwe waziindi zyakuzungaana kwamugoti wakuzwa wa valve magesi ulaswaangene abwaamba bwa valve, pitch ya valve stem, antoomwe amweelwe wamitwe iijisi nsinga. Kweelede kubalwa kweendelanya a M=H/ZS (M mweelwe woonse wazinguluka eezyo chibelesyo chamagesi ncheelede kusika, mpawo H nibulamfu bwakujula kwavalvu, S nimweelwe wantambo ya valve stem drive, Z nimweelwe wamitwe yantambo zya stem).

D. Bulamfu bwamusamu

Kumavwili aatanta aazinguluka ziindi zyiingi, ikuti bupati bupati buzumizyidwe aachitila chamagesi tabukonzyi kwiinda mumulyango wamavwili aajisi zibelesyo, tabukonzyi kusanganyigwa kuba mavwili aamagesi. Aboobo, bupati bwamukati bwachikozyano chamagesi bweelede kuba bupati kwiinda bupati bwaanze bwachikobela chachikobela chitanta. Kumavwili aakonzya kujokoloka zibeela-beela alimwi amavwili aajisi nsinga zyamudima mumavwili aakonzya kujokoloka ziindi zinji, nokuba kuti takuyandiki kulanga-langa kwiinda kwabwamba bwacikobela, bupati bwacikobela alimwi abwaamba bwanzila yakukkiya azyalo zyeelede kulanga-langwa cakumaninina ciindi notusala, kutegwa vvavuvu libeleke kabotu ciindi nolyabunganizigwa.

E. Kufwambaana kwakuzwa

Kuti kujalula akujala kwakufwambaana kwa valve ya butterfly kwafwambaana loko, nchuubauba kupanga nkomo yamaanzi. Aboobo, kufwambaana kwakujalula akujala kweelede kusalwa kweendelanya abukkale bwakubelesya bwiindene.
