ʻOkoʻa ma waena o ka Wafer a me ka Lug Type Butterfly Valve

ʻO ka valve butterfly kahi ʻano valve hapaha-huli e kaohi ana i ke kahe o kahi huahana i loko o kahi pipeline.

Nā kiwikā pepekeua hoʻokaʻawale pinepine ʻia i ʻelua ʻano: ʻano lug a me ke ʻano wafer. ʻAʻole hiki ke hoʻololi ʻia kēia mau ʻāpana mechanical a he mau pono a me nā noi like ʻole. Hōʻike ke alakaʻi ma lalo nei i nā ʻokoʻa ma waena o nā ʻano valve butterfly ʻelua a pehea e koho ai i ka valve kūpono no kāu mau pono.

Kiwikā Pepeiao Kaila-Lug

ʻO ka maʻamau, hana ʻia nā kiwikā pepeke ʻano lug i ka metala e like me ka hao ductile a i ʻole ke kila. Loaʻa iā lākou nā lugs i hoʻopaʻa ʻia me nā wili i kau ʻia ma nā flanges valve no nā pilina bolt.He kūpono nā kiwikā pulelehua kaila lug no ka lawelawe hopena-o-ka laina akā ua ʻōlelo mau ʻia kahi flange makapō.

Kiwikā Pulelehua Kaila-Wafer

ʻO ka hapa nui o nā kiwikā pepeke ʻano wafer ua hana ʻia me nā lua ʻehā e kūlike ana me ka pipeline i hoʻopili ʻia. Ua hoʻolālā ʻia ka kiwikā e hoʻopaʻa ma waena o ʻelua mau flanges i kāu hana paipu. Kūpono ka hapa nui o nā kiwikā pepeke wafer i ka hapa nui o nā kūlana flange. Hoʻokumu ka noho kiwikā rapa a i ʻole EPDM i kahi sila ikaika loa ma waena o ka kiwikā a me ka pilina flange.ʻAʻole e like me nā kiwikā pepeke ʻano lug, ʻaʻole hiki ke hoʻohana ʻia nā kiwikā pepeke ʻano wafer ma ke ʻano he mau wēlau paipu a i ʻole ka lawelawe hopena o ka laina. Pono e pani ʻia ka laina holoʻokoʻa inā pono ka mālama ʻana i kekahi ʻaoʻao o ka kiwikā.
