ʻIke pinepine wau i nā nīnau a ka mea kūʻai aku e like me lalo: "Aloha, Beria, makemake wau i ka valve puka, hiki iā ʻoe ke haʻi mai no mākou?"ʻO nā kīpē puka kā mākou huahana, a kamaʻāina mākou iā lākou.ʻAʻole pilikia ka ʻōlelo, akā pehea wau e hāʻawi ai iā ia i kahi ʻōlelo e pili ana i kēia nīnau?Pehea e hiki ai i ka haʻi ʻōlelo ke kōkua i nā mea kūʻai aku e loaʻa nā kauoha, a kūʻai paha i nā huahana e pono ai nā mea kūʻai aku?Akaka, ʻaʻole lawa kēia mau ʻikepili wale nō.I kēia manawa, nīnau pinepine au i ka mea kūʻai aku "he aha ke ʻano o ka valve puka e pono ai ʻoe, he aha ke kaomi, he aha ka nui, loaʻa iā ʻoe ka waena a me ka mahana?"E huhū loa kekahi mau mea kūʻai, makemake wau i kahi kumukūʻai, nīnau mai ʻoe iaʻu i nā nīnau he nui, pehea ʻoe ʻaʻole ʻoihana.ʻAʻole nīnau kekahi poʻe, a hāʻawi wale mai iaʻu i kahi ʻōlelo.Akā, he ʻoiaʻiʻo anei kā mākou hana ʻole?ʻO ka mea ʻē aʻe, no ka mea ʻoihana mākou a kuleana iā ʻoe e nīnau mākou i kēia mau nīnau.ʻAe, maʻalahi ka haʻi ʻana, akā ʻaʻole maʻalahi ke kōkua i nā mea kūʻai aku e loaʻa nā kauoha.I kēia manawa, e noʻonoʻo kākou i nā kikoʻī e pono e hoʻolohe ʻia i ka nīnau a me ka haʻi ʻana o nā ʻīpuka puka mai nā ʻaoʻao aʻe.
ʻO ka ʻōlelo maʻamau, ʻo nā ʻano huaʻōlelo o nā kīwaha ʻīpuka e pili ana i ke ʻano (kookoo hāmama a i ʻole koʻokoʻo ʻeleʻele), kaomi, anawaena, mea, a me ke kaumaha.Ma kēia ʻatikala, kūkākūkā wale mākou i nā ʻīpuka paʻa i hoʻopaʻa ʻia.
1. Ke ano: Elua ano o na kiwi puka paa pahee, kiwi puka puka puka a me pu kiwi puka puka huna.Pono ka ʻīpuka piʻi kiʻekiʻe i kahi wahi hana nui a ʻoi aku ka kūpono no nā papahana pipeline ma ka honua.ʻAʻole e neʻe ka puʻu valve i luna a i lalo, no laila kūpono ia no nā papahana pipeline ma lalo.
2. Pumi: No nā ʻīpuka i hoʻopaʻa ʻia i ka palupalu, ʻo ke kaomi maʻamau ʻo PN10-PN16, Class150.No ke ʻano o ke kiʻekiʻe o ke kaomi, e hoʻopōʻino ʻia ka pā i uhi ʻia i ka lāʻau.ʻAʻole mākou e paipai i ka hoʻohana ʻana i nā ʻīpuka paʻa i hoʻopaʻa ʻia;
3. Nui: He mea maʻalahi kēia, ʻoi aku ka nui o ka caliber, ʻoi aku ka pipiʻi o ka valve;
4. Material: Ma keʻano o ka mea,ʻoi aku ka kiko'ī.ʻO ka mea maʻamau, ke kamaʻilio nei mākou e pili ana i nā mea mai kēia mau ʻaoʻao, ke kino valve, ka pā valve, ka lāʻau;no nā ʻīpuka i hoʻopaʻa paʻa ʻia, ʻo ka mea maʻamau i hoʻohana ʻia ʻo ke kino hao ductile.ʻO ka pā kīpē he pāpaʻi ductile hao.Nui nā koho no ka pahu valve, ka pahu kila kalapona, ka lāʻau 2cr13, ka lāʻau kila kila, a ʻokoʻa ka ʻili o ka ʻīpuka o ka ʻīpuka mai ka hao hao a me ke keleawe keleawe.No ka pāpaʻi ʻino, maʻamau Ua ʻōlelo ʻia e hoʻohana i nā nati keleawe a me nā ʻeke keleawe, ʻaʻole i loaʻa i ka media corrosive, a ua lawa nā nati hao maʻamau a me nā kini hao.
5. Kaumaha: ʻO ke kaumaha maʻaneʻi e pili ana i ke kaumaha o kahi valve hoʻokahi,ʻo ia hoʻi kahi mea i maʻalahi ke nānāʻoleʻia.Ua hoʻoholo ʻia ka mea, a ua hoʻoholo ʻia ke kumukūʻai no ka valve puka o ka nui like?ʻino ka pane.I mea e hoʻokō ai i nā koi mākeke like ʻole, hana nā mea hana valve i ka mānoanoa o nā valves, ʻo ia ka hopena inā ʻo ka mea like, ʻo ka nui ka nui, ka lōʻihi o ke kūkulu ʻana, ʻo ke anawaena o waho o ka flange a ua like ka mamao waena o ka lua flange, akā ʻaʻole like ka mānoanoa o ke kino valve, a ʻokoʻa hoʻi ke kaumaha o ka ʻīpuka o ka nui like.No ka laʻana, ʻo ka DN100 like, DIN F4 ʻeleʻele ʻeleʻele ʻeleʻele i ka ʻīpuka kīwaha, loaʻa iā mākou 6 mau ʻano o ke kaumaha, 10.5kg, 12kg, 14kg, 17kg, 19kg, 21kg, maopopo, ʻoi aku ke kaumaha o ke kaumaha, ʻoi aku ka pipiʻi o ke kumukūʻai.Ma ke ʻano he mea kūʻai ʻoihana, pono ʻoe e ʻike i ke ʻano o ke kūlana hana e hoʻohana ʻia ai ka huahana āu e makemake ai, he aha ka maikaʻi o ka mea kūʻai aku, a me ke ʻano o ke kumukūʻai e ʻae ʻia e ka mea kūʻai.No kā mākou hale hana, makemake maoli mākou i nā mea kūʻai aku e kūʻai i nā huahana kiʻekiʻe, no laila e emi loa ke kūʻai aku ma hope.Eia nō naʻe, ma muli o ke koi mākeke, pono mākou e hoʻokaʻawale i kā mākou huahana i mea e loaʻa ai ka ʻāpana mākeke.
Ma o ka nānā ʻana i nā ʻaoʻao i luna, manaʻo wau e ʻoi aku ka maikaʻi o kou ʻike ʻana i ke kūʻai ʻana i nā ʻīpuka i hoʻopaʻa ʻia.Inā he mau nīnau kāu e pili ana i ke kūʻai ʻana i nā ʻīpuka puka, e ʻoluʻolu e kelepona iā Zhongfa Valve, a e hana mākou i ka mea maikaʻi loa e kōkua iā ʻoe e hoʻoponopono i nā pilikia.
