ʻO Valve kekahi o nā mea hana nui i ka ʻōnaehana hoʻokele wai.I kēia manawa, ʻo ka hoʻohana nui ʻana o ka valve me ka ʻaila a me ke kinoea, ka mana, ka ʻenekinia kemika, ka lako wai a me ka mālama ʻana i ka wai, ka hana pepa a me ka metallurgy.Ma waena o ia mea, ʻo ka aila a me ke kinoea, ka mana a me ka ʻoihana kemika nā mea nui loa o ka valve.Wahi a ka wānana a McIlvaine, ka mea wānana mākeke, e piʻi ka noi o ka valve ʻoihana i 100 biliona kālā.Ua manaʻo ʻia mai 2015 a 2017, e mālama ka nui o ka ulu ʻana o ka mākeke valve ʻoihana ma kahi o 7%, ʻoi aku ka kiʻekiʻe ma mua o ka ulu ʻana o ka ulu ʻana o ka ʻoihana valve ʻoihana honua.

ʻO Valve ka mea hoʻomalu no ka ʻōnaehana hoʻoili wai, loaʻa nā hana o ka ʻoki ʻana, hoʻoponopono, hoʻololi i ka muliwai, pale ʻana i ka countercurrent, stabilization voltage, shunt or overflow and decompression.Hoʻokaʻawale ʻia ʻo Valve i ka valve control industry a me ka valve civilian.Hoʻohana ʻia ka valve ʻoihana e hoʻomalu i ke kahe o ka media, ke kaomi, ka mahana, ke kahua wai a me nā ʻāpana ʻenehana ʻē aʻe.Ma muli o nā kūlana like ʻole, hiki ke hoʻokaʻawale ʻia ka valve ʻoihana i nā ʻano like ʻole.No nā ʻano hoʻoponopono, hoʻokaʻawale ʻia ka valve i ka hoʻoponopono, ʻoki ʻana, hoʻoponopono a ʻoki ʻia;e pili ana i nā mea o ka valve, ua hoʻokaʻawale ʻia ka valve i ka metala, non-metal a me ka liner metala;ma muli o nā ʻano hoʻokele, hoʻokaʻawale ʻia ka valve ʻoihana i ke ʻano uila, ʻano pneumatic, ʻano hydraulic a me nā ʻano manual;ma muli o ka mahana, ua hoʻokaʻawale ʻia ka valve i loko o ka valve wela ultralow, valve haʻahaʻa haʻahaʻa, valve wela maʻamau, valve wela wela a me ka valve wela kiʻekiʻe a hiki ke hoʻokaʻawale ʻia ka valve i loko o ka valve vacuum, valve haʻahaʻa haʻahaʻa. kiʻekiʻe kaomi valve.

Hoʻokumu ʻia ka ʻoihana valve Kina mai ka makahiki 1960.Ma mua o 1980, hiki iā Kina ke hana ma mua o 600 mau ʻano a me 2,700 mau ana o nā huahana valve, nele i ka hiki ke hoʻolālā i ka valve me nā ʻāpana kiʻekiʻe a me nā ʻike loea kiʻekiʻe.No ka hoʻokō ʻana i ke koi no ka valve i loaʻa nā ʻāpana kiʻekiʻe a me nā ʻike loea kiʻekiʻe i hoʻokumu ʻia e ka ʻoihana a me ka mahiʻai ma Kina e ulu nui nei, mai ka makahiki 1980.Ua hoʻomaka ʻo Kina e hoʻohana i ka manaʻo e hoʻohui i ka hoʻomohala kūʻokoʻa a me ka hoʻokomo ʻana i ka ʻenehana e hoʻomohala i nā ʻenehana valve.Hoʻonui kekahi mau ʻoihana valve koʻikoʻi i ka noiʻi ʻenehana a me ka hoʻomohala ʻana, e hoʻonui ana i ke kai kiʻekiʻe o ka lawe ʻana i ka ʻenehana valve.I kēia manawa, ua hana mua ʻo Kina i ka valve puka, ka valve honua, ka valve throttle, ball valve, butterfly valve, diaphragm vale, plug valve, check valve, safety valve, reduction valve, drain valve a me nā valve ʻē aʻe, me 12 mau ʻano, ʻoi aku ma mua o 3,000 nā hiʻohiʻona a me 40,000 ana.

Wahi a nā statics o Valve World, ʻo ka noi o ka mākeke honua no ka valve ʻoihana i loaʻa i ka drilling, transport and petrifaction.ʻO ka aila a me ke kinoea ka hapa kiʻekiʻe loa, hiki i 37.40%.Ke koi nei no ka mana a me ka ʻenekinia kemika, ʻo ia ka helu no 21.30% a me 11.50% o ka noi ʻana o ka mākeke valve ʻoihana honua.ʻO ka noi mākeke ma nā palapala noi mua ʻekolu he 70.20% o ka nui o ka noi mākeke.Ma Kina, ʻenehana kemika, mana a me ka aila a me ke kinoea ka mākeke kūʻai nui o ka valve.ʻO ka koi no ka valve i kēlā me kēia helu no 25.70%, 20.10% a me 14.70% o ka nui o ka noi.ʻO ka nui o ka noi no 60.50% o ka nui o ka noi valve.

Ma ke ʻano o ka noi mākeke, ʻo ka koi no ka valve i ka mālama wai a me ka hydropower, ka mana nuklea a me ka ʻoihana ʻaila aila e hoʻomau i ke ʻano ikaika i ka wā e hiki mai ana.

I ka mālama ʻana i ka wai a me ka hydropower, ʻo ka hoʻolālā i hoʻopuka ʻia e ke Keʻena Nui o ka ʻAha Moku'āina e kuhikuhi ana i ka makahiki 2020, hiki i ka mana o ka hydropower maʻamau ma kahi o 350 miliona kilowatts.ʻO ka ulu ʻana o ka hydropower e koi nui i ka valve.ʻO ka ulu mau ʻana o ka hoʻopukapuka ʻana ma ka hydropower e hoʻoulu i ka pōmaikaʻi i ka valve ʻoihana.
