Ductile Iron Dual Plate Check Valve
✧ Hōʻike
ʻO ka ductile iron dual plate check valve he ʻano o ka ʻenehana ʻenehana i hoʻolālā ʻia e pale i ka hoʻihoʻi ʻana i loko o kahi pipeline a i ʻole ka ʻōnaehana kaʻina.Hana ʻia kēia ʻano valve me ka hao ductile, kahi mea i ʻike ʻia no kona ikaika a paʻa.ʻO ka hoʻolālā pālua pālua e pili ana i ka hoʻonohonoho ʻana o ka valve, aia i loko o ʻelua mau papa hinged a i ʻole disc e wehe ana i ka pane ʻana i ke kahe i mua a kokoke i ka pale ʻana i ka hoʻihoʻi. , a me nā hana ʻoihana.Hoʻokomo pinepineʻia lākou i loko o nā pipelines e hōʻoia i ke kahe unidirectional o ka wai a iʻole ke kinoea i ka wā e pale ana i ka holoʻana o ka hoʻohuli i hiki ke alakaʻi i ka pōʻino o ka pūnaewele a iʻole inefficiency.Ductile hao ua kohoʻia e like me ka mea no kēia mau kiwikā ma muli o kona maikaʻi loa mechanical a me ka corrosion. kūpono ia no nā noi koi.Hāʻawi ka hoʻolālā papa ʻelua i kahi hopena paʻa a maikaʻi no ka pale ʻana i ka hoʻihoʻi ʻana, a ʻo nā papa hinged e ʻae i ka pane wikiwiki i ka hoʻololi ʻana, e hoʻemi ana i nā poho kaomi. nā koi noi like ʻole.Hoʻolālā maʻamau a hana ʻia lākou e like me nā kūlana ʻoihana e like me API, AWWA, a me ISO e hōʻoia i kā lākou hana, hilinaʻi, a me ka palekana. nā alakaʻi, a i ʻole ka launa pū me kāu noi, e ʻoluʻolu e haʻi mai iaʻu i hiki iaʻu ke kōkua hou aku iā ʻoe.
✧ Nā hiʻohiʻona o ka Ductile Iron Dual Plate Check Valve Wafer type
1. He pōkole ka lōʻihi o ka hale, ʻo 1/4 a i ka 1/8 wale nō ka lōʻihi o ka pahu hoʻopaʻa flange maʻamau.
2. liʻiliʻi liʻiliʻi, māmā ke kaumaha, ʻo kona kaumaha he 1/4 a 1/20 wale nō o ka pahu hoʻopaʻa lohi lohi maʻamau.
3. paʻa koke ka disc o ka pahu hoʻopaʻa paʻa, a liʻiliʻi ke kaomi hāmare wai
4. Hiki ke hoʻohana ʻia ka paipu hoʻopaʻapaʻa a i ʻole ka paipu kū pololei, maʻalahi ke hoʻouka
5. He maʻemaʻe ke ala kahe o ka pahu hoʻopaʻa paʻa, liʻiliʻi ke kūpaʻa wai
6. hana koʻikoʻi, hana hoʻopaʻa maikaʻi
7. He pōkole ka hahau diski, he liʻiliʻi ka hopena pani pani pani
8. ka hale holoʻokoʻa, maʻalahi a paʻa, nani ke ʻano
9. lōʻihi lawelawe ola, hilinaʻi kiʻekiʻe
✧ ʻO nā pono o ka Ductile Iron Dual Plate Check Valve Wafer type
I ka wā o ka wehe ʻana a me ka pani ʻana o ka pahu kila kila, no ka mea, ʻoi aku ka liʻiliʻi o ka friction ma waena o ka disc a me ka ʻili hoʻopaʻa ʻana o ke kino valve ma mua o ko ka valve puka, ʻaʻole hiki ke ʻaʻahu.
ʻO ka wehe ʻana a i ʻole ka pani ʻana o ka pahu valve he pōkole, a he hana ʻokiʻoki hilinaʻi loa ia, a no ka mea ʻo ka hoʻololi ʻana o ke awa noho valve e like me ka hahau ʻana o ka disc valve, kūpono loa ia no ka hoʻoponopono. o ke kahe ana.No laila, kūpono loa kēia ʻano valve no ka ʻoki ʻoki a i ʻole ka hoʻoponopono a me ka throttling.

✧ Mahope o ke kuai ana
Ma ke ʻano he Ductile Iron Dual Plate Check Valve Wafer type a me ka mea kūʻai aku, hoʻohiki mākou e hāʻawi i nā mea kūʻai aku me ka lawelawe ma hope o ke kūʻai aku kiʻekiʻe, me kēia mau mea:
1. Hāʻawi i nā alakaʻi hoʻohana huahana a me nā manaʻo mālama.
2.No nā hemahema i hana ʻia e nā pilikia maikaʻi o ka huahana, hoʻohiki mākou e hāʻawi i ke kākoʻo ʻenehana a me ka hoʻoponopono pilikia i loko o ka manawa pōkole loa.
3.Except no ka pōʻino i hanaʻia e ka hoʻohana maʻamau, hāʻawi mākou i nā lawelawe hoʻoponopono manuahi a me nā pani pani.
4. Ke hoʻohiki nei mākou e pane wikiwiki i nā pono lawelawe o ka mea kūʻai aku i ka wā o ka hōʻoia huahana.
5. Hāʻawi mākou i ke kākoʻo ʻenehana no ka wā lōʻihi, nā lawelawe kūkākūkā pūnaewele a me nā lawelawe hoʻomaʻamaʻa.ʻO kā mākou pahuhopu ka hāʻawi ʻana i nā mea kūʻai aku i ka ʻike lawelawe maikaʻi loa a hoʻolilo i ka ʻike o nā mea kūʻai aku i mea ʻoluʻolu a maʻalahi.
