ʻO ka maʻamau ʻo AWWA ka The American Water Works Association i paʻi mua i nā palapala consensus ma 1908. I kēia lā, aia ma mua o 190 AWWA Standards.Mai ke kumu a hiki i ka mālama ʻana, mai ka mālama ʻana i ka hāʻawi ʻana, uhi ʻo AWWA Standards i nā huahana a me nā kaʻina hana e pili ana i nā wahi āpau o ka mālama wai a me ka lako.ʻO AWWA C504 o ka ʻelele maʻamau, ʻo ia ke ʻano o ka pahu lele lele.
ʻElua mau ʻano o ka valve butterfly AWWA C504, ʻoi aku ka liʻiliʻi o ka midline line soft seal a me ka sila ʻelua eccentric soft seal, maʻamau, ʻoi aku ka liʻiliʻi o ke kumukūʻai o ka midline soft seal ma mua o ka pālua eccentric, ʻoiaʻiʻo, hana ʻia kēia e like me nā koi o nā mea kūʻai aku.ʻO ka mea maʻamau, ʻo ke kaomi hana no AWWA C504 he 125psi, 150psi, 250psi, flange pili kaomi ʻana o CL125, CL150, CL250.
Hoʻohana nui ʻia ka valve butterfly AWWA C504 i nā papahana mālama wai, ʻo ka wai e pono ai ka wai me ka ʻole o ka haumia, ʻo nā hiʻohiʻona o ka sila paʻa e hoʻoikaika i ka hana sealing o ka valve, i hiki ai i ka valve ke hoʻokō i ka leakage 0.I ke koho ʻana i ka mea kino valve, ʻo ka hao ductile ka mea nui, a hiki i ke kila kalapona ke hiki.Loaʻa ka koho o ka valve disc sealing ring, EPDM, NBR, NR, e like me nā koi o ka mea kūʻai aku e koho.
Ke hoʻohālikelike ʻia me ka EN558-13,14 series butterfly valves, ʻo ka AWWA C504 butterfly valve he ʻoi aku ka mānoanoa o ke kino a ʻoi aku ka mānoanoa o ke anawaena spindle, a he mau ʻokoʻa liʻiliʻi nō hoʻi i nā ʻāpana ʻē aʻe, hiki ke ʻike ʻia ma ka papa ʻaina.ʻO kaʻoiaʻiʻo, no ka hana, ʻaʻohe ʻokoʻa nui me nā kīwī pēpē i hoʻopaʻa ʻia i ka lāʻau.
He aha nā mea hana hiki ke hana i ka AWWA C504 butterfly valve ma Kina?E like me kaʻu i ʻike ai, ʻaʻole nui nā mea hana i hiki ke hana i ka valve butterfly AWWA C504, ʻoi aku ka nui o nā ʻoihana i ʻike i ka hana ʻana i ka valve butterfly EN558-13/14 series, a ʻaʻohe ʻike nui i ka hana ʻana i ka valve butterfly AWWA C504, Tianjin Zhongfa ʻO Valve kekahi o nā mea hana i hiki ke hana i ka valve butterfly AWWA C504, aia ʻo Zhongfa Valve i kāna mold ponoʻī a me kāna hale hana hana ponoʻī, hiki ke hoʻopau i ka hana ʻana o ka valve butterfly me ka maikaʻi a me ka nui.
ʻO kēia ka pahu lele o AWWA C504 i hana ʻia e Tianjin Zhongfa Valve, Inā makemake ʻoe e ʻike hou aku e pili ana i nā huahana AWWA C504, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou.
