I kēia manawa, ua hoʻopau mākou i ka hana maʻamau o ka DN1200 150LB kalapona kila poepoenā puka pāno nā mea kūʻai aku honua. Hana ʻia me ke kila kalapona SJ235, ua hana kūikawā ʻia kēia puka flange poepoe no nā puka hoʻokahe wai mālie. Hoʻolaha nui ʻia ia ma nā hoʻokahe wai kahe o ke kūlanakauhale, nā hale hana hoʻomaʻemaʻe wai ʻino, nā kikowaena pamu kahakai a me nā paipu mālama wai, e hana ana ma ke ʻano he lako hana anti-backflow hilinaʻi no nā ʻōnaehana hoʻokahe wai.

Hoʻohana kēia puka ʻīpuka poepoe kila kalapona i ka wili hao kalapona i hoʻohui ʻia no ka ikaika kūkulu kiʻekiʻe, ke kūpaʻa wai maikaʻi loa a me ke kūpaʻa hopena. Hoʻokomo ʻia nā iwi ʻaoʻao i hoʻoikaika ʻia ma ka lau puka me nā loulou hinge i hoʻomaikaʻi ʻia e hōʻoia i ka hana maʻalahi me ka ʻole o ka jamping. Pale aku nā pine hinge kila kila i ka popo a me ka hopu ʻana ma lalo o nā kūlana wai lōʻihi a hoʻolōʻihi i ke ola lawelawe o ka puka ʻīpuka.

Mālama ka uhi epoxy hana kiʻekiʻe i ka puka pā mai ka waikawa, alkali, wai ʻino a me ka pala o ka wai kai, e kūpono ai no nā wahi waho, nā wahi pulu ma lalo o ka honua a me ke kahakai e pīpī ai i ka paʻakai. Hana aunoa ka puka pā ma o ka ʻokoʻa o ke kaomi wai, ʻaʻohe pono o ka lako mana a i ʻole nā ​​mea hoʻoikaika kōkua. Hoʻopau ia i nā ʻōnaehana hoʻomalu uila keu, e hōʻemi nui ana i ka hoʻopukapuka kālā a me nā kumukūʻai mālama lōʻihi no nā papahana hoʻokahe wai.

Kūlike ka flange me nā kūlana ANSI 150LB. Hoʻokō ka lua DN1200 nui i nā koi hoʻokahe wai kahe kiʻekiʻe. Hoʻololi ka ʻōnaehana sila elastic composite i ka deformation liʻiliʻi o ke ʻano e hoʻokō ai i ka pani hilinaʻi, e pale pono ana i ke kahe hou ʻana o ka wai kai a me ka wai muliwai a me ka haumia o ka pipeline. Hāʻawi ka ʻōnaehana i hoʻomaikaʻi ʻia i ka mīkini i ka hana anti-seismic maikaʻi loa e kū i nā piʻi wai koke i nā kau waikahe. Kākoʻo ka pilina flange i ka hoʻokomo wikiwiki ʻana ma kahi a me ka mālama maʻalahi. Loaʻa nā nui maʻamau, nā helu kaomi a me nā uhi anti-corrosion no ka puka flap poepoe. Hoʻomaʻamaʻa ʻia kēlā me kēia ʻāpana i ka paʻa hydrostatic a me ka hoʻāʻo ikaika ma mua o ka hoʻouna ʻana.

Ke hoʻohālikelike ʻia me nā puka sluice maʻamau, ʻo ka puka flap kila kalapona e noho ana i kahi liʻiliʻi a ʻaʻole pono e nānā lima mau. ʻO ia ka hopena anti-backflow makemake ʻia no nā puka kikowaena pamu, nā paipu interception sewer a me nā papahana kaohi waikahe. Hāʻawi mākou i nā kiʻi loea piha a me nā palapala hōʻoia nānā a ʻae i nā kauoha i hana nui ʻia no nā papahana honua. Welina i nā nīnau mai nā ʻoihana ʻenekinia honua a me nā mea kūʻai aku i ka ʻoihana wai.
