flange check valve

Hiki i ka Proco ProFlex 710 duckbill check valve ke hoʻopuehu pono i ka hoʻokuʻu ʻia ʻana o ka wai kai ma Istanbul, Turkey.
Loaʻa i ka Istanbul Water Authority kahi lāʻau lapaʻau wai olaola e lawelawe ana ma kahi o 15 miliona mau kānaka ma Istanbul, Turkey. No ka hoʻokō ʻana i nā lula kaiapuni ʻoi aku ka paʻakikī, ua hoʻopili ka Mana Wai i ka Marine Consulting Group (MCG) i ka pūnāwai o 2017 e ʻimi i nā huahana kūpono e hāʻawi i ka diffusion kūpono no kāna hoʻokuʻu ʻana i ka wai ʻino kai.
Ua hana pū ʻo MCG me Proco e hoʻolālā a hoʻolālā i ka duckbill diffuser e hoʻokipa ai i ka puka wai hoʻoheheʻe o ka hale hoʻoheheʻe wai ma o ka paipu kila 87 iniha ke anawaena. Hoʻonui ka paipu i 1.35 mau mile (2230 mika) ma lalo o ka moana a hoʻokuʻu i 154 kapuaʻi ma lalo o ka ʻilikai.
Pono ʻo Proco e mālama i kekahi mau pilikia no kēia papahana. ʻO ka hopohopo, ʻo ka diffuser a me ka duckbill check valve e pōʻino ʻia e ka moku e kaalo ana. I mea e hoʻoponopono ai i kēia pilikia, pono ʻo Proco e hoʻoholo i ka lōʻihi diffuser kūpono. Ma kēia papahana, ʻo ka lōʻihi o ka diffuser ma kahi o 741.5 kapuaʻi ma ka hope loa o ka 1.5-mile lele anti-fall tube.
I ka wā ma mua, ua koi pinepine ʻia nā ʻenekinia a me nā mea hana ʻaelike e hana i nā pili flange puka makapō i kekahi mau awa i hiki ai iā lākou ke hana ma kahi kahe haʻahaʻa haʻahaʻa a wehe ʻia e hiki ai ke kahe nui i ka wā e hiki mai ana. E helu i ka helu kahe nui loa no ka mālama ʻana i ka nui o ka wai ʻino no nā makahiki he 20 e hiki mai ana. Eia nō naʻe, ʻaʻole e hana ka kahe kahe o kēia manawa ma ka hopena kiʻekiʻe. No laila, pono ʻo Proco lāua ʻo MCG e hoʻolālā i kahi pahu kiko nui kūpono e hoʻopau i kēia hopohopo.
Manaʻo ʻo MCG i ka Mana Wai e hoʻohana i ka Proco ProFlex 710 duckbill check valve ma kēia papahana, me ʻelua mau ʻauwai 10-inihi no kēlā me kēia awa. ʻO ka pahu hoʻopaʻa Duckbill me ke anawaena (250 mm).
Hoʻohana ʻia ka pāpaʻi duckbill no ka pale ʻana i ka hoʻihoʻi ʻana i loko o ka pāhana hoʻoheheʻe kai hohonu/diffuser. Ke pale nei ka Proco ProFlex 710 duckbill check valve i nā pāpale makapō ma kekahi mau awa i nā makahiki mua o ka hana. Eia kekahi, ʻo ka hoʻohana ʻana o Proco ProFlex 710 duckbill check valves e hoʻopau i ka pono o nā flanges puka makapō no ka mea hiki i ka pipeline ke holo maikaʻi mai ka hoʻomaka mua ʻana, a laila e hōʻemi ana i ka hana mālama a hoʻemi i ka manawa no nā mea divers e hoʻohui i nā valve hou i ka wā e hiki mai ana.
Hoʻohana ʻia ka pahu hoʻopaʻa duckbill i kēia papahana no ka pale ʻana i ka wai paʻakai mai ke komo ʻana i ka pipeline ke loaʻa ʻole ke kaomi inlet. Ke haʻahaʻa ke kaomi poʻo a ʻaʻohe kahe inlet, ʻo ka ʻokoʻa o ke kaomi poʻo ma waena o ka wai kai a me ka wai hoʻoheheʻe e hoʻokomo ka wai kai i ka pipeline. Inā ʻaʻole pale ʻia kēia hoʻihoʻi ʻana, hiki ke paʻa a paʻa paha ke awa, a komo ke ola moana i ka pipeline. ʻO ka hopena, ʻaʻole hiki ke loaʻa ka ratio dilution i helu ʻia a hoʻolālā ʻia. Hiki ke hoʻonui i ka jet velocity ka duckbill check valve a hāʻawi i kahi waiwai dilution ʻē aʻe mai nā ʻīpuka flap kuʻuna, ʻoiai ma nā kahe kahe haʻahaʻa.
Eia kekahi, hiki i ka elastomer engineering o ka Proco ProFlex 710 duckbill check valve ke mālama i kona hoʻomanaʻo ma hope o ka wehe ʻia ʻana a pani ʻia paha no ka manawa lōʻihi, a ʻo ka valve he 100% kūpaʻa i nā barnacles a me nā algae, kahi mea nui o ka mālama wai paʻakai. papahana. Ua hāʻawi pū ka hui ʻenekinia o Proco i ke kōkua piha i ka hāʻawi ʻana i nā helu pohō poʻo.
Ma hope o ka hoʻokomo ʻana i ka ʻūhā nānā duckbill Proco ProFlex 710, e hoʻopiha i ka ʻaha i hoʻopau ʻia me ka ea e mālama ai i ka buoyancy, a laila e kauo i kahi kūlana, a laila e hāʻule i lalo o ke kai. Hoʻokomo kēia i ka valve Proco 710 i ka hana a hiki i ka hoʻoheheʻe ʻana i ka blowdown kūpono ma kēlā me kēia 46 valves. Ua holo piha ka ʻōnaehana ma ka ʻāina, a ke hoʻomau nei ʻo Proco i ke kōkua a me ka ʻike ʻenekinia e like me kēia ʻōnaehana ma ka pae honua.
Ke kono nei nā limahana Rainwater Solutions i nā ʻoihana ʻoihana e koho i nā mea a lākou e manaʻo ai he ʻoi loa ka maikaʻi a me ka hana hou a me nā hana wai ʻino i ʻike ʻia ma ka Annual Reference Guide. I nā mahina 18 i hala iho nei, pono nā papahana a pau i ka hoʻolālā a i ʻole ke kūkulu ʻana.
