Pono ʻoe e kauoha i nā kiwikā pōpō no kahi papahana, akā ʻaʻole ʻoe maopopo i ka nui pololei. ʻO ke kauoha ʻana i ka nui hewa ke ʻano o ka lohi a me nā hoʻihoʻi pipiʻi, he ʻeha poʻo ʻaʻole pono i ka luna kūʻai.
Hoʻokumu ʻia nā nui o ka valve pōpō ma ka nui o ka paipu maʻamau a lākou e hoʻopili ai. Loaʻa pinepine lākou mai nā nui liʻiliʻi 1/2 ʻīniha no ka hoʻohana ʻana i ka home a i nā nui nui 12 ʻīniha no nā noi ʻoihana, e hahai ana i nā kūlana honua e like me NPS a me DN.
ʻO ka loaʻa ʻana o ka nui kūpono ka hana nui loa i ke kauoha ʻana. Me he mea lā he maʻalahi, akā me nā kūlana like ʻole i hoʻohana ʻia a puni ka honua, hiki ke huikau. Hana pū wau me nā hoa hana e like me Budi ma Indonesia, a pono mākou e maopopo loa i ka nui e hōʻoia i ka loaʻa ʻana o kāna mau mea kūʻai aku i ka mea a lākou e pono ai no kā lākou mau papahana. ʻO ka hoʻohana ʻana i ka nui kūpono e hōʻoia i kahi kūpono kūpono, kahi sila hilinaʻi, a me kahi ʻōnaehana e hana e like me ka hoʻolālā ʻana. ʻAʻole kēia e pili ana i kahi ʻāpana wale nō; e pili ana i ka holomua o ke kau ʻana holoʻokoʻa.
He aha nā nui e loaʻa ai nā kiwikā pōpō?
Ke nānā nei ʻoe i kahi papa inoa mea hoʻolako a me he mea lā pau ʻole ka papa inoa o nā nui o ka valve. Ke noʻonoʻo nei ʻoe i nā nui no nā hana maʻamau a me nā papahana ʻoihana kūikawā.
Loaʻa nā kiwikā pōpō i nā nui like ʻole e kūlike me kēlā me kēia ana paipu maʻamau. No ka hapa nui o nā noi PVC, ʻo kēia maʻamau mai 1/2 ʻīniha (DN15) a i 12 ʻīniha (DN300).
ʻO ka laulā o nā nui o ia hoʻi aia kahikiwikā poepoeno aneane kēlā me kēia hana, mai kahi maʻalahipiula wai mālapili i kahi wai nui. ʻO ke kī, ʻo ia ka hoʻomaopopo ʻana i nā nui i hoʻohana ʻia no nā noi. Ma ke ʻano he mea hana, mālama mākou i nā nui maʻamau i hiki i kā mākou mau hoa ke loaʻa i kā lākou mea e pono ai me ka ʻole o nā manawa alakaʻi lōʻihi. No kahi mākeke e like me Indonesia, loaʻa ka lako mākaukau o nā hale noho a menā nui o ka hoʻoinu waimai ka 1/2″ a i ka 4″ he mea koʻikoʻi ia no Budi e lawelawe pono ai i kāna mau mea kūʻai aku. Hōʻoia kēia e hiki i kahi mea hana hana ke loaʻa mau i ka valve a lākou e pono ai no ka hana plumbing a me ke kūkulu ʻana i kēlā me kēia lā.

He aha nā nui o nā valve maʻamau?
Lohe ʻoe i nā huaʻōlelo e like me NPS, DN, Imperial, a me Metric. Hiki i kēia ke hoʻohuikau i ke kauoha ʻana mai nā ʻāina like ʻole a hana i kahi pilikia o ka loaʻa ʻana o kahi ʻāpana i kūpono ʻole i kāu mau paipu.
Hoʻākāka ʻia nā nui o nā kiwikā maʻamau e ka ʻōnaehana NPS (Nominal Pipe Size), e hoʻohana ana i nā ʻīniha, a i ʻole ka ʻōnaehana DN (Diameter Nominal), e hoʻohana ana i nā millimeters. Hōʻoia nā ʻōnaehana ʻelua i ka launa pū ʻana ma waena o nā paipu a me nā mea hoʻopili.
ʻO kēia mau kūlana ka ʻōlelo o ka ʻoihana paipu. Ua hana ʻia lākou i mea e kūpono ai kahi kiwikā i hana ʻia ma kekahi ʻāina i kahi paipu i hana ʻia ma kekahi. ʻO ka helu nui he "nominal," ʻo ia hoʻi he inoa ia no ka nui, ʻaʻole he ana pololei. ʻAʻohe puka o kahi kiwikā 2-ʻīniha he 2,000 ʻīniha pololei. Ua hoʻolālā ʻia e kūpono i kahi paipu 2-ʻīniha. Ke hoʻomaopopo nei i nā mea ʻeluaNPSa meDNhe mea nui ia no kekahi mea e komo ana i ke kālepa honua, e like me aʻu a me kaʻu mau hoa. Hoʻopau ia i nā kānalua āpau a hōʻoia i ka hana pū ʻana o nā ʻāpana me ka ʻole o ka pilikia.
Ke hoʻomaopopo nei i nā kūlana NPS a me DN
Eia kahi pakuhi hoʻololi maʻalahi no nā nui maʻamau. ʻO ka loaʻa ʻana o kēia ma ka lima e maʻalahi ai ke hoʻololi ma waena o nā ʻōnaehana ʻelua a pale i kekahi huikau.

Pehea e ʻike ai i ka nui o ka valve?
Aia ʻoe ma kahi hana a pono ʻoe e hoʻololi i kahi kiwikā kahiko. Ua lepo ka kiwikā, a ʻaʻohe ʻōpala a pepa paha, no laila ʻaʻole ʻoe maopopo i ka nui e kauoha ai.
No ka ʻike ʻana i ka nui o ka valve, e nānā i ke kino valve no nā māka i kālai ʻia a paʻi ʻia paha. E ʻike ʻoe i kahi ana ʻīniha (e laʻa, "2") a i ʻole kahi waiwai DN (e laʻa, "DN50").
Hoʻokomo pinepine nā mea hana i ka māka nui ma luna o ka huahana. ʻO kēia ke ala wikiwiki loa a hilinaʻi hoʻi e ʻike ai. E nānā pono i ke kino nui o ka valve. I kekahi manawa ʻoi aku ka ʻike ʻia o ka logo brand a i ʻole ka helu kaomi, akā e kau ʻia ka hōʻailona nui ma laila. Ma lunanā kiwikā poepoe uniona maoli, e ʻike paha ʻoe i ka nui i hōʻailona ʻia ma nā nati uniona. Ke loaʻa iā ʻoe kēia helu, hiki iā ʻoe ke hilinaʻi piha i ke kauoha ʻana i kahi pani kūpono. Mālama kēia nānā maʻalahi i ka manawa nui a pale i ka hoʻonāukiuki o ka loaʻa ʻana o ka ʻāpana hewa.
He aha e hana ai inā ʻaʻohe mau hōʻailona
Inā ua ʻelemakule loa a ua ʻino paha ka valve a ʻaʻole hiki iā ʻoe ke loaʻa kekahi mau māka, he mau koho kāu. Mai ana wale i ka ʻaoʻao o waho o ka valve, no ka mea, hiki i kēia ke kuhihewa.
- E nānā i ka paipu:ʻO kēia ke ʻano hana maikaʻi loa. ʻO ka paipu i hoʻopili ʻia ai ka valve e paʻi ʻia kona nui ma kona lōʻihi. E nānā i nā māka e like me "PVC Schedule 40 2 INCH" a i ʻole "UPVC PN10 DN50". E kūlike ka nui o ka valve me ka nui o ka paipu.
- E ana i ka puka o loko:E ana pono i ke anawaena o loko o ka puka kahi e kahe ai ka wai. E kokoke loa kēia ana i ka nui maʻamau. No ka laʻana, ʻo kahi valve 2-'īniha e loaʻa kahi anawaena o loko ma kahi o 2 'īniha.
- Hoʻohālikelike i kahi Valve i ʻike ʻia:Inā loaʻa iā ʻoe nā valves ʻē aʻe o ka nui i ʻike ʻia, hiki iā ʻoe ke hana i kahi hoʻohālikelike kino pololei.
He aha ka manaʻo o DN50 ma kahi valve?
Ke nānā nei ʻoe i kahi palapala kikoʻī loea mai kahi mea hoʻolako ʻEulopa. ʻIke ʻoe iā "DN50" a pono ʻoe e ʻike pono i ka nui o ia mea ma nā huaʻōlelo e maopopo ai i kāu hui kūloko.
ʻO DN50 ke kū nei no "Diameter Nominal 50 millimeters". ʻO ia ka nui maʻamau metric honua e like me ka nui 2-'īniha (NPS) i hoʻohana ʻia ma ʻAmelika Hui Pū ʻIa a me nā wahi ʻē aʻe.
Hoʻokumu ka ʻōnaehana DN i kahi kūlana honua no nā mea āpau.Anawaena Nominal"ʻo ia hoʻi ka inoa no ka nui, ʻaʻole he ana paʻa. Ma ka hoʻohana ʻana iā DN, hiki i kahi luna papahana ma Indonesia e like me Budi ke kauoha mai kahi mea hana e like me aʻu ma Kina, a ʻike maopopo mākou i ka mea a mākou e kamaʻilio nei. Hoʻopau ia i ka huikau ma waena o nā ʻōnaehana metric a me nā imperial a ʻo ia ke kumu o ka hoʻohālikelike honua i kā mākou ʻoihana. Ke ʻike ʻoe iā DN, ʻike ʻoe e hoʻohana ana ʻoe i kaKūlana ISOHōʻoia kēia e kūpono kahi valve DN50 i kekahi paipu DN50 a i ʻole ke kūpono, me ka nānā ʻole i kahi o ka honua i hana ʻia ai.
Nā Nui DN Maʻamau a me ko lākou ʻīniha like
ʻO ka hoʻomaopopo ʻana i kēia pilina he mea nui ia no ka hana ʻana me nā huahana o ka honua.

ʻO kēia kūlana hoʻohālikelike ka mea e hiki ai iā mākou ke kūkulu i nā ʻōnaehana wai hilinaʻi ma ka pae honua.
