Moʻolelo o ka hoʻomohala ʻana o ka ʻoihana Valve Kina (1)

Nānā nui

Valvehe huahana koʻikoʻi i ka mīkini maʻamau.Hoʻokomo ʻia ma luna o nā paipu like ʻole a i ʻole nā ​​​​mea hana e hoʻomalu i ke kahe o ka waena ma o ka hoʻololi ʻana i ka wahi o ke kahawai i loko o ka valve.ʻO kāna mau hana: hoʻohui a ʻoki ʻia i ka waena, pale i ke kahe ʻana i hope, hoʻoponopono i nā ʻāpana e like me ke kaomi ʻana a me ke kahe ʻana, hoʻololi i ke ala kahe o ka waena, hoʻokaʻawale i ka waena a pale paha i nā pipelines a me nā lako mai ka overpressure, etc.

Nui nā ʻano o nā huahana valve, i māhele ʻia ikiwi puka, pāpū honua,hoʻopaʻa pahu, pahu kinipopo,lele lele.E like me ka mea, ua maheleia i ke keleawe kila, hoolei hao, kalapona kila, hao hao, austenitic kila, ferritic-austenitic lua-phase kila, nickel-ma muli o ka hao, titanium huila, 'enekinia plastics a me ka ceramic kiwikā, etc. , aia nā'ōmole kūikawā e like me nā kumukūʻai kiʻekiʻe e like me nā kumukūʻai kiʻekiʻeKa laulā o nā ʻāpana valve, ka nui inoa mai DN1 (unit in mm) a i DN9750;kaomi nominal mai ultra-vacuum o 1× 10-10 mmHg (1mmHg = 133.322Pa) i ke kaomi ki'eki'e loa o PN14600 (unit o 105 Pa);ʻO ka mahana hana mai ka wela haʻahaʻa loa o -269i ka wela kiʻekiʻe loa o 1200.

Nā huahana valve hoʻohana nui ʻia i nā ʻāpana like ʻole o ka hoʻokele waiwai o ka ʻāina, e like me ka aila, ke kinoea maoli, ka aila a me ka hoʻomaʻemaʻe ʻana a me ka hoʻomaʻamaʻa ʻana a me nā ʻōnaehana kaʻa pipeline, nā huahana kemika, nā lāʻau lapaʻau a me nā ʻōnaehana meaʻai, hydropower, thermal power and nuclear power production system;Hoʻohana nui ʻia nā ʻano valve like ʻole i nā ʻōnaehana hoʻomehana a me ka mana, nā ʻōnaehana hana metallurgical, nā ʻōnaehana wai no nā moku, nā kaʻa, nā mokulele a me nā mīkini haʻuki like ʻole, a me nā ʻōnaehana wai a me nā ʻōnaehana wai no ka ʻāina mahiʻai.Eia kekahi, ma nā kahua o nā ʻenehana hou e like me ka pale a me ka aerospace, hoʻohana pū ʻia nā ʻano valve me nā waiwai kūikawā.

ʻO nā huahana Valve ka hapa nui o nā huahana mechanical.Wahi a nā helu helu o nā ʻāina ʻoihana ʻē aʻe, ʻo ka waiwai hoʻopuka o nā valves e pili ana i ka 5% o ka waiwai hoʻopuka o ka ʻoihana mīkini holoʻokoʻa.Wahi a nā helu helu, he 28,000 mau pahu kaʻa kaʻana like ʻana o kahi mea kanu nuklea kuʻuna i haku ʻia me ʻelua miliona kilowatt, a ma kahi o 12,000 he mau mokuahi nuklea.ʻO kahi paʻakikī petrochemical nui hou e koi ai i nā haneli haneli o nā kiwi like ʻole, a ʻo ka hoʻopukapuka ʻana i nā valves ma ke ʻano he 8% a 10% o ka huina kālā i nā lako.

 

Kūlana maʻamau o ka ʻoihana valve ma Kina kahiko

01 Ka wahi hānau o ka ʻoihana valve o Kina: Shanghai

Ma Kina kahiko, ʻo Shanghai ka wahi mua e hana ai i nā kīwaha ma Kina.I ka makahiki 1902, ua hoʻomaka ʻo Pan Shunji Copper Workshop, aia ma Wuchang Road, Hongkou District, Shanghai, e hana i nā ʻāpana liʻiliʻi o nā kīʻaha kīʻaha ma ka lima.He ʻano moa keleawe i hoʻolei ʻia ke kī kī.ʻO ia ka mea hana valve mua loa ma Kina i ʻike ʻia i kēia manawa.I ka makahiki 1919, ua hoʻomaka ʻo Deda (Shengji) Hardware Factory (ka mea ma mua o Shanghai Transmission Machinery Factory) mai kahi kaʻa kaʻa liʻiliʻi a hoʻomaka e hana i nā moa keleawe liʻiliʻi liʻiliʻi, nā kīwaha honua, nā ʻīpuka puka a me nā hydrants ahi.Ua hoʻomaka ka hana ʻana i nā kiwi hao hao i ka makahiki 1926, me ka nui o ka inoa inoa ʻoi loa o NPS6 (ma nā iniha, NPS1 = DN25.4).I loko o kēia manawa, ua wehe ʻia nā hale hana lako e like me Wang Yingqiang, Dahua, Lao Demao a me Maoxu e hana i nā kiwi.Ma hope iho, ma muli o ka piʻi ʻana o ka noi no nā kīwī paipu ma ka mākeke, ua wehe ʻia kekahi pūʻulu o nā ʻoihana lako, nā hale hana hao, nā hale hana one (casting) a me nā ʻoihana mīkini e hana i nā kīwaha ma hope o kekahi.

Hoʻokumu ʻia kahi hui hana valve ma nā wahi o Zhonghongqiao, Waihongqiao, Daming Road a me Changzhi Road ma Hongkou District, Shanghai.I kēlā manawa, ʻo nā hōʻailona kūʻai maikaʻi loa ma ka mākeke kūloko ʻo "Horse Head", "Three 8", "Three 9", "Double Coin", "Iron Anchor", "Chicken Ball" a me "Eagle Ball".Hoʻohana nui ʻia nā huahana haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka hao pahu pahu no nā kiwi paipu i ke kūkulu ʻana a me nā keʻena maʻemaʻe, a ua hoʻohana pū ʻia ka liʻiliʻi o nā pahu hao hao ma ka ʻoihana lole lole māmā.He liʻiliʻi loa kēia mau hale hana, me ka ʻenehana hope, nā mea kanu maʻalahi a me nā puka valve haʻahaʻa, akā ʻo lākou ka wahi hānau mua loa o ka ʻoihana valve o Kina.Ma hope mai, ma hope o ka hoʻokumu ʻia ʻana o ka Shanghai Construction Hardware Association, ua hui pū kēia mau mea hana valve i ka hui ma hope o kekahi a lilo i hui wai.lālā.

 

02 ʻElua mau mea kanu valve nunui

I ka hoʻomaka ʻana o 1930, ua hana ʻo Shanghai Shenhe Machinery Factory i nā ʻīpuka hao haʻahaʻa haʻahaʻa haʻahaʻa ma lalo o NPS12 no ka hana wai.I ka makahiki 1935, ua hoʻokumu ka hale hana i kahi hui pū me Xiangfeng Iron Pipe Factory a me Xiangtai Iron Co., Ltd. nā mea kuleana e kūkulu i Daxin Iron Factory (ka mea ma mua o Shanghai Bicycle Factory), ma 1936 Hoʻopau a hoʻokomo i ka hana, aia ma kahi o 100 mau limahana. , me 2.6 zhang (1 zhang3.33m) nā lathes a me nā mea hoʻokiʻekiʻe, ka mea nui e hana ana i nā mea hana ʻenehana a me nā mea mining, hoʻolei i nā paipu wai hao a me nā pahu hao, ʻo ka nui o ka nui o ka valve ʻo NPS6 ~ NPS18, a hiki iā ia ke hoʻolālā a hāʻawi i nā ʻāpana piha piha no nā mea kanu wai, a lawe ʻia nā huahana i Nanjing, Hangzhou a me Beijing.Ma hope o ka “August 13″ ka poʻe hoʻouka kaua o Iapana i Shanghai i ka makahiki 1937, ua hoʻopau ʻia ka hapa nui o nā mea kanu a me nā mea hana i loko o ka hale hana e nā pū kī a Iapana.I ka makahiki aʻe, hoʻonui ʻia ke kapikala a hoʻomaka hou i ka hana.NPS14 ~ NPS36 i hoʻolei ʻia i nā ʻīpuka hao, akā ma muli o ke kaumaha o ka hoʻokele waiwai, nā ʻoihana palaualelo, a me nā hana austerity, ʻaʻole hiki iā lākou ke hoʻōla a hiki i ka pō o ka hoʻokumu ʻana o New Kina.

I ka makahiki 1935, ʻelima mau mea kuleana e like me Li Chenghai, he kanaka pāʻoihana aupuni, i hoʻokumu pū ʻia ʻo Shenyang Chengfa Iron Factory (ka mea mua o Tieling Valve Factory) ma ke alanui Shishiwei, Nancheng District, Shenyang City.Hoʻoponopono a hana i nā kiwi.Ma 1939, ua hoʻoneʻe ʻia ka hale hana i Beierma Road, Tiexi District no ka hoʻonui ʻana, a ua kūkulu ʻia ʻelua mau hale hana nui no ka hoʻolei ʻana a me ka mīkini.Ma ka makahiki 1945, ua ulu ia i 400 mau limahana, a ʻo kāna mau huahana nui: nā boilers nui, nā kiwi keleawe keleawe, a me nā kiwi puka hao ma lalo o ka honua me ka nui o ka inoa ma lalo o DN800.ʻO Shenyang Chengfa Iron Factory kahi mea hana valve e hakakā nei e ola ma Kina kahiko.

 

03 ʻO ka ʻoihana valve ma hope

I ka wā o ke Kaua Anti-Iapana, nui nā ʻoihana ma Shanghai a me nā wahi ʻē aʻe i neʻe i ke komohana hema, no laila ua piʻi ka nui o nā ʻoihana ma Chongqing a me nā wahi ʻē aʻe ma hope, a hoʻomaka ka ʻoihana e ulu.I ka makahiki 1943, ua hoʻomaka ʻo Chongqing Hongtai Machinery Factory a me Huachang Machinery Factory (ʻo nā ʻoihana ʻelua nā mea ma mua o Chongqing Valve Factory) i hoʻomaka e hoʻoponopono a hana i nā ʻāpana paipu a me nā puʻu haʻahaʻa haʻahaʻa, kahi i hana nui i ka hoʻomohala ʻana i ka hana kaua ma hope a me ka hoʻoponopono ʻana i nā kīwila. kiwikā.Ma hope o ka lanakila o ka Anti-Japanese War, Lisheng Hardware Factory, Zhenxing Industrial Society, Jinshunhe Hardware Factory a me Qiyi Hardware Factory i wehe ʻia e hana i nā kiwi liʻiliʻi.Ma hope o ka hoʻokumu ʻia ʻana o New China, ua hoʻohui ʻia kēia mau hale hana i Chongqing Valve Factory.

I kēlā manawa, kekahinā mea hana valvema Shanghai ua hele pū i Tianjin, Nanjing a me Wuxi e kūkulu i nā hale hana no ka hoʻoponopono ʻana a me ka hana ʻana i nā kiwi.ʻO kekahi mau hale hana lako, nā hale paipu hao, nā ʻoihana mīkini a i ʻole nā ​​​​hale moku ma Beijing, Dalian, Changchun, Harbin, Anshan, Qingdao, Wuhan, Fuzhou a me Guangzhou ua hana pū kekahi i ka hoʻoponopono ʻana a me ka hana ʻana i kekahi mau pahu paipu.
