ʻO ka valve butterfly, he ʻano ia o ka valve-turn valve e hoʻomalu i ke kahe ʻana o kahi huahana i loko o kahi paipu.
ʻO nā kiwi kīpēHoʻohui pinepine ʻia i ʻelua ʻano: lug-style a me wafer-style.ʻAʻole hiki ke hoʻololi ʻia kēia mau ʻāpana mechanical a loaʻa iā lākou nā pōmaikaʻi a me nā noi.ʻO ke alakaʻi ma lalo nei e wehewehe i nā ʻokoʻa ma waena o nā ʻano valve butterfly ʻelua a pehea e koho ai i ka valve kūpono no kāu pono.
ʻO nā kiwi lele lele ʻano Lug ka mea maʻamau i haku ʻia me ka metala e like me ka hao ductile a i ʻole ke kila.Hōʻike lākou i nā lugs i hoʻopaʻa ʻia i hoʻopaʻa ʻia ma luna o nā flanges valve no nā pili bolt.He kūpono nā kiwi lele lele ʻano Lug no ka lawelawe hope o ka laina akā ʻōlelo mau ʻia ka flange makapō.
Hoʻohana ʻia ka hapa nui o nā kiwi wailele ʻano wafer me nā puka ʻehā e kūlike me ka pipeline pili.Hoʻolālā ʻia ka valve e hoʻopaʻa ma waena o ʻelua flanges i kāu hana paipu.ʻO ka hapa nui o nā pahu wafer butterfly kūpono i ka hapa nui o nā kūlana flange.Hoʻokumu ka pahu pahu a EPDM i kahi sila ikaika loa ma waena o ka valve a me ka pili flange.ʻAʻole e like me nā kiwi lele lele, ʻaʻole hiki ke hoʻohana ʻia nā kiwi lele ʻano wafer ma ke ʻano he paipu a i ʻole ka lawelawe hope o ka laina.Pono e pani ʻia ka laina holoʻokoʻa inā pono e mālama ʻia kēlā me kēia ʻaoʻao o ka valve.
