Boemo bo akaretsang ba indasteri ea li-valve Chaena ea khale
01 Sebaka sa tsoalo ea indasteri ea li-valve tsa China: Shanghai
Chaena ea khale, Shanghai e ne e le sebaka sa pele sa ho etsa li-valve Chaena. Ka 1902, Pan Shunji Copper Workshop, e Seterateng sa Wuchang, Seterekeng sa Hongkou, Shanghai, e ile ea qala ho etsa lihlopha tse nyane tsa lipompo tsa teapot ka letsoho. Thepa ea teapot ke mofuta oa mokōkō oa koporo. Ke moetsi oa li-valve oa pele ka ho fetisisa Chaena ea tsejoang ho fihlela joale. Ka 1919, Deda (Shengji) Hardware Factory (eo e neng e le teng pele ho Shanghai Transmission Machinery Factory) e ile ea qala ka baesekele e nyenyane 'me ea qala ho hlahisa likoti tsa koporo tse bophara bo bonyenyane, li-valve tsa globe, li-valve tsa heke le lisebelisoa tsa mollo. Ho etsoa ha li-valve tsa tšepe tse entsoeng ka tšepe ho qalile ka 1926, ka boholo ba lebitso la NPS6 (ka lisenthimithara, NPS1 = DN25.4). Nakong ena, lifeme tsa hardware tse kang Wang Yingqiang, Dahua, Lao Demao le Maoxu le tsona li ile tsa buloa ho etsa li-valve. Kamora moo, ka lebaka la keketseho ea tlhokahalo ea li-valve tsa lipeipi 'marakeng, sehlopha se seng sa lifeme tsa li-hardware, lifeme tsa tšepe, lifeme tsa lehlabathe (casting) le lifeme tsa mochini li ile tsa buloa ho etsa li-valve ka ho latellana.
Sehlopha sa tlhahiso ea li-valve se thehoa libakeng tsa Zhonghongqiao, Waihongqiao, Daming Road le Changzhi Road Seterekeng sa Hongkou, Shanghai. Ka nako eo, lihlahisoa tse rekisoang ka ho fetisisa 'marakeng oa lehae e ne e le "Hlooho ea Lipere", "Three 8", "Three 9", "Double Coin", "Iron Anchor", "Chicken Ball" le "Eagle Ball". Lihlahisoa tsa li-valve tsa tšepe tse nang le khatello e tlaase li sebelisoa haholo-holo bakeng sa li-valve tsa lipeipi mohahong oa mohaho le oa bohloeki, 'me li-valve tse nyenyane tsa tšepe li sebelisoa hape lekaleng la indasteri ea masela. Lifeme tsena li nyane haholo ka tekanyo, li na le mahlale a morao-rao, lisebelisoa tse bonolo tsa semela le tlhahiso e tlase ea li-valve, empa ke libaka tsa pele tsa indasteri ea li-valve tsa China. Hamorao, ka mor'a ho thehoa ha Shanghai Construction Hardware Association, baetsi bana ba li-valve ba kene mokhatlong o mong ka mor'a o mong 'me ba fetoha sehlopha sa litsela tsa metsi. setho.
02 Limela tse peli tse kholo tsa tlhahiso ea li-valve
Mathoasong a 1930, Shanghai Shenhe Machinery Factory e ile ea etsa li-valve tsa heke ea tšepe e nang le khatello e tlase ka tlase ho NPS12 bakeng sa mesebetsi ea metsi. Ka 1935, feme e ile ea theha khoebo e kopanetsoeng le Xiangfeng Iron Pipe Factory le Xiangtai Iron Co., Ltd. , e nang le 2.6 zhang (1 zhang≈3.33m) lathes le lisebelisoa tsa ho phahamisa, haholo-holo tse hlahisang lisebelisoa tsa indasteri le tsa merafo, lipeipi tsa metsi a tšepe le li-valve tsa tšepe tse entsoeng ka tšepe, boholo ba lebitso la valve ke NPS6 ~ NPS18, 'me E ka rala le ho fana ka lisebelisoa tse feletseng tsa li-valve bakeng sa limela tsa metsi, le lihlahisoa li romelloa ho Nanjing, Hangzhou le Beijing. Ka mor'a hore "August 13" bahlaseli ba Majapane ba hape Shanghai ka 1937, boholo ba setsi le thepa ea fektheri e ile ea senngoa ke lithunya tsa Japane. Selemong se latelang e ile ea eketsa chelete le ho tsosolosa mosebetsi. NPS14 ~ NPS36 li-valve tsa heke ea tšepe, empa ka lebaka la khatello ea maikutlo ea moruo, khoebo e botsoa, le ho putlama ha maemo, ha ba so ka ba khona ho hlaphoheloa ho fihlela bosiung ba ho theoa ha New China.
Ka 1935, beng ba liabo ba bahlano ba kenyelletsang Li Chenghai, rakhoebo oa naha, ka kopanelo ba thehile Shenyang Chengfa Iron Factory (ea pele ho Tieling Valve Factory) tseleng ea Shishiwei, Seterekeng sa Nancheng, Shenyang City. Lokisa le ho etsa li-valve. Ka 1939, feme e ile ea fallisetsoa Beierma Road, Seterekeng sa Tiexi bakeng sa katoloso, 'me ho ile ha hahuoa lithupelo tse peli tse kholo tsa ho etsa le ho etsa mechine. Ka 1945, e ne e se e hōlile ho ba basebetsi ba 400, 'me lihlahisoa tsa eona tse ka sehloohong e ne e le: li-boilers tse kholo, li-valve tsa koporo, le li-valve tsa heke tsa tšepe tse ka tlas'a lefatše tse nang le boholo bo ka tlaase ho DN800. Shenyang Chengfa Iron Factory ke moetsi oa li-valve ea sokolang ho phela Chaena ea khale.
03Indasteri ea li-valve ka morao
Nakong ea Ntoa ea Khahlano le Majapane, likhoebo tse ngata tsa Shanghai le libakeng tse ling li ile tsa fallela ka boroa-bophirimela, kahoo palo ea likhoebo tsa Chongqing le libakeng tse ling tse ka morao e ile ea eketseha, 'me indasteri ea qala ho hola. Ka 1943, Chongqing Hongtai Machinery Factory le Huachang Machinery Factory (feme ka bobeli e ne e le pele ho Chongqing Valve Factory) e ile ea qala ho lokisa le ho etsa likarolo tsa lipeipi le li-valve tsa khatello e tlaase, tse ileng tsa phetha karolo e kholo ho nts'etsopele tlhahiso ea nako ea ntoa ka morao le ho rarolla baahi. li-valve. Kamora tlhōlo ea Ntoa e Khahlanong le Majapane, Lisheng Hardware Factory, Zhenxing Industrial Society, Jinshunhe Hardware Factory le Qiyi Hardware Factory li ile tsa buloa ka tatellano ho hlahisa li-valve tse nyane. Kamora ho theoa ha New China, lifeme tsena li ile tsa kopanngoa ho Chongqing Valve Factory.
Ka nako eo, ba bangbaetsi ba li-valveShanghai le eona e ile ea ea Tianjin, Nanjing le Wuxi ho haha lifeme tsa ho lokisa le ho etsa li-valve. Lifeme tse ling tsa lisebelisoa tsa tšepe, lifeme tsa lipeipi tsa tšepe, lifeme tsa mechini kapa libaka tsa likepe tsa Beijing, Dalian, Changchun, Harbin, Anshan, Qingdao, Wuhan, Fuzhou le Guangzhou le tsona li nkile karolo ho lokisa le ho etsa li-valve tsa lipeipi.
