Ua hoʻonoho mua ʻia ka valve butterfly ma ke ʻano he leakage valve a hoʻohana wale ʻia ma ke ʻano he pā valve.
ʻAʻole hiki i ka makahiki 1950 ka hoʻohana maoli ʻia ʻana o ka lāʻau synthetic, a ua hoʻohana ʻia ka lāʻau synthetic i ke apo noho o ka valve butterfly, a ʻo ka valve butterfly ma ke ʻano he ʻoki ʻoki i hoʻomaka ai.
ʻO ka hoʻokaʻawale ʻana o nā valve butterfly:
Hoʻokaʻawale ʻia nā kīwaha Butterfly e like me ke ʻano, pili piping, plate, etc.
Kiwikā lele lele waena:
He hale kahi e noho ai ka ʻili o ka noho ma waho o ka ʻōpala valve ma ka ʻili like me ke kikowaena o ke kumu valve.
Hoʻopili ʻia ka ʻili o loko o ke kino valve me ke ʻano o ke apo noho lāʻau.ʻO kēia ka valve i hōʻike ʻia e ka valve butterfly plate i kapa ʻia ʻo waena.E like me ka hoʻopili ʻana o ka lāʻau, hoʻohana maikaʻi ʻia ka ikaika repulsive elastic o ka valve butterfly a me ka ʻili o ka noho, i hiki ke hoʻopaʻa ʻia ka noho maikaʻi.
ʻO ka valve lele lele eccentric:
Aia ke kikowaena hoʻololi (stem) o ka diski ma ke kikowaena o ke anawaena o ka valve, a ʻo ke kumu o ka disc he ʻano eccentric.ʻO ke apo o ka noho e like me ke ʻano eccentric hoʻokahi a he hana hoʻopaʻa maikaʻi.
ʻO ka valve butterfly tri-eccentric:
He hale ia e hoʻohui ʻia ai ka eccentricity ʻelua, a ʻo ke kikowaena cone o ka pā peʻapeʻa e hili ʻia mai ke kikowaena o ke anawaena valve o ka hanana.
ʻAʻole pili ka triple eccentricity i ke apo o ka noho metala i ka wā e wehe ʻia ai a pani ʻia ka papa pepeke, a ʻo ka papa pepeke wale nō ka mea e hoʻoikaika ai i ke apo noho e like me ka pahu pani i ka wā e paʻa pono ai.
Wafer butterfly valve:
Hoʻohana ka valve butterfly wafer i nā bolts stud e hoʻohui i ka valve ma waena o nā ʻāpana paipu ʻelua.Aia ʻelua ʻano o ka protrusions, ke ʻano lug piha a me ke ʻano lug piha ʻole.
Hiki ke hana ʻia kēia mau valve e kā mākouMīkini Valve Kūikawā.
