ʻO Valves nā huahana me nā palena haʻahaʻa haʻahaʻa, a he ikaika loa ka hoʻokūkū mākeke.E pili ana i ka hāʻawi ʻana i ka mākeke valve, ua hoʻokumu ʻia ma ke kūkulu ʻana i nā hana ʻenehana.ʻO nā mea hoʻohana nui loa o nā valve ʻo ia ka ʻoihana petrochemical, ʻāpana mana, ʻāpana metallurgical, ʻoihana kemika a me ka ʻoihana kūkulu kūlanakauhale.Hoʻohana nui ʻia ka ʻoihana petrochemical i nā kiwi puka maʻamau API, nā kiwi honua a me nā kiwi nānā;ke hoʻohana nui nei ka ʻāpana mana i nā ʻīpuka puʻupuʻu kiʻekiʻe, nā kīwaha honua, nā kiwi nānā a me nā kiwi palekana no nā hale mana a me kekahi mau kiwi lele haʻahaʻa haʻahaʻa a me nā kiwi puka no ka hoʻolako ʻana i ka wai a me nā kiwi wai;ʻO ka ʻoihana kemika e hoʻohana nui i nā ʻīpuka ʻīpuka Stainless steel, nā kiwi honua, nā kiwi nānā;ʻO ka ʻoihana metallurgical ka hoʻohana nui ʻana i nā puʻupuʻu butterfly anawaena haʻahaʻa haʻahaʻa, nā kiwi hoʻopaʻa oxygen a me nā kiwi pōpō oxygen;Hoʻohana nui nā keʻena kūkulu kūlanakauhale i nā kiwi puʻu haʻahaʻa, e like me nā pipelines wai o ke kūlanakauhale ka hoʻohana nui ʻana i nā ʻīpuka puka puka nui, a ʻo ke kūkulu hale ka hoʻohana nui ʻana i ka laina waena No nā kiwi lele, hoʻohana nui ʻia nā kiwi lele lele i hoʻopaʻa ʻia no ka hoʻomehana kūlanakauhale;hoʻohana nui ʻia nā kiwi puka pāpaʻa a me nā kinipōpō no nā paipu aila;hoʻohana nui ʻia nā ʻili kinipōpō kila kila ma ka ʻoihana lāʻau lapaʻau;hoʻohana nui ʻia nā kiwi pōpō kila kila ma ka ʻoihana meaʻai.Hoʻohana nui ʻia nā valves i ka ʻoihana mālama wai, ʻoi aku ka nui o nā huahana valve haʻahaʻa haʻahaʻa, e like me nā kīwaha butterfly, nā ʻīpuka puka, a me nā kiwi.Ua hoʻomaopopo ʻia aia i kēia manawa ʻoi aku ma mua o 2,000 mau hui valve me kahi pae ma ka mākeke, ʻo ka hapa nui o ia mau mea aia ma Jiangsu, Zhejiang a me Central Plains.Ma muli o nā koi haʻahaʻa no ka ʻenehana huahana, ʻoi aku ka ikaika o ka hoʻokūkū.

Mai ka 1980s, ua hoʻomaka koʻu ʻāina e hoʻonohonoho i nā ʻoihana koʻikoʻi e hoʻolauna i ka ʻenehana holomua a me nā lako hana e like me ka hoʻolālā ʻana a me ka ʻenehana o nā huahana like ʻole mai nā ʻāina ʻē, no laila ua hoʻomaikaʻi wikiwiki ʻia ka ʻenehana hana valve a me ka maikaʻi o ka huahana. ka pae o nā ʻāina ʻē i ka makahiki 1980.I kēia manawa, ua hiki i nā mea hana valve kī home ke hoʻolālā a hana i nā ʻano valve like ʻole e like me nā kūlana honua e like me nā kūlana honua ISO, DIN German standards, AWWA American standards, a ua hōʻea kekahi mau mea hana i ka pae kiʻekiʻe o ka honua.ʻOiai ua hoʻomaikaʻi maikaʻi ʻia ka pae holoʻokoʻa o ka ʻoihana valve i ka Makahiki Hou, ʻaʻole paʻa ka maikaʻi, e like me ka holo ʻana, kahe, kahe ʻana, a me ka leakage e ʻike pinepine ʻia i loko o nā valve home.Eia kekahi, aia kekahi ʻokoʻa ma waena o koʻu ʻāina e kākoʻo ana i ka valve a me nā ʻāina kūkulu.

Ma kekahi ʻaoʻao, ke kū nei nā huahana valve o koʻu ʻāina i nā manawa hoʻomohala maikaʻi.Me ka hoʻololi ʻana o ka hoʻomohala ʻana i ka aila i uka a me nā māla aila o waho, a me ka hoʻomohala ʻana o ka ʻoihana mana mai ka mana wela ma lalo o 300,000 kilowatts i ka mana wela, hydropower a me ka mana nuklea ma luna o 300,000 kilowatts, pono e hoʻololi nā huahana valve i kā lākou hana a me nā loli like. ma ke kahua o ka noi lako.ʻāpana.Hoʻohana maʻamau nā ʻōnaehana kūkulu kūlanakauhale i ka nui o nā puʻupuʻu haʻahaʻa haʻahaʻa, a ke ulu nei i ka mālama ʻana i ke kaiapuni a me ka mālama ʻana i ka ikehu, ʻo ia hoʻi, ka hoʻololi ʻana mai nā ʻīpuka hao haʻahaʻa haʻahaʻa i hoʻohana ʻia i ka wā i hala a i nā kiwi palapa pāpaʻi pili i ka honua, ke kaulike. nā kiwikā, nā kiwikā lele lele sila, a me nā kiwi lele lele waena.ʻO ka hoʻomohala ʻana i nā papahana kaʻa aila a me ke kinoea i ke kuhikuhi o nā pipelines e pono ai ka nui o nā ʻīpuka palahalaha a me nā kiwi pōpō.ʻO ka ʻaoʻao ʻē aʻe o ka hoʻomohala ʻana i ka ikehu, ʻo ia ka mālama ʻana i ka ikehu, no laila, mai ka manaʻo o ka mālama ʻana i ka ikehu, pono e hoʻomohala a hoʻomohala ʻia nā pahele mahu i nā palena kiʻekiʻe subcritical a supercritical.

Ke hoʻomohala nei ke kūkulu ʻana i ka mana mana i ka hoʻomohala nui, no laila, pono nā kīwaha palekana nui-caliber a me ke kiʻekiʻe a me nā puʻupuʻu hoʻohaʻahaʻa hoʻohaʻahaʻa, a koi pū ʻia nā kīwaha wehe wikiwiki a pani.No nā pono o nā papahana piha, ua hoʻomohala ka hoʻolako ʻana i nā valves mai kahi ʻano like ʻole i nā ʻano like ʻole a me nā kikoʻī.Ke piʻi aʻe nei ke ʻano e hāʻawi ʻia nā valve i koi ʻia e kahi papahana ʻenekinia e ka mea hana valve.

Akā ma kekahi ʻaoʻao, pono mākou e lawe i nā pilikia he nui i ka mākeke valve.ʻOiai ua hoʻokumu ʻia ka mākeke valve o koʻu ʻāina i kahi hui pū ʻana o nā mokuʻāina, hui, hui pū, ʻoihana a me nā hui pilikino.I ka hoʻokūkū ikaika o ka mākeke, e koi ana i ka hoʻomohala mau ʻana, ke nānā nei nā ʻoihana i kēia mau pilikia: hana ikaika e hōʻemi i nā kumukūʻai hana, e kālele ana i ka hoʻomaikaʻi ʻana i ka hana a me ka pono o ka huahana;ka hoʻomohala ʻana i nā huahana ʻenehana kiʻekiʻe kiʻekiʻe a i ʻole ka hana ʻana i kahi ʻāpana liʻiliʻi o nā huahana maʻamau ʻole;e hele ana i ka palapala hōʻoia maikaʻi International o nā huahana valve;pono e ulu nā huahana valve i ke ala o ka mālama ʻana i ke kaiapuni a me ka mālama ʻana i ka ikehu.Eia nō naʻe, ʻaʻole hiki ke ʻae ʻia kekahi mau mea hana hewa ʻole e ʻimi nei i ka waiwai e like me kā lākou kumu a ʻaʻole kānalua e hōʻino i ka pono o nā poʻe ʻē aʻe e hoʻopau i ka ulu ʻana o ka mākeke huahana valve.
