Boemo bo akaretsang ba indasteri ea li-valve Chaena ea khale
01 Sebaka seo indasteri ea li-valve ea Chaena e qalileng ho hlaha ho sona: 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 fumanehang Wuchang Road, Seterekeng sa Hongkou, Shanghai, e ile ea qala ho etsa lihlopha tse nyane tsa lipompo tsa teapot ka letsoho. Faucet ea teapot ke mofuta oa cock ea koporo e entsoeng ka foreimi. Ke moetsi oa pele oa li-valve Chaena ea tsejoang ho fihlela joale. Ka 1919, Deda (Shengji) Hardware Factory (e neng e le pele ho Shanghai Transmission Machinery Factory) e qalile ka baesekele e nyane 'me ea qala ho hlahisa li-cock tsa koporo tse bophara bo bonyenyane, li-valve tsa globe, li-valve tsa heke le li-hydrant tsa mollo. Tlhahiso ea li-valve tsa tšepe e entsoeng ka foreimi e qalile ka 1926, ka boholo bo phahameng 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. Ka mora moo, ka lebaka la keketseho ya tlhokeho ya di-valve tsa diphaephe mmarakeng, sehlopha se seng sa difeme tsa di-hardware, difeme tsa tshepe, difeme tsa ho etsa di-foundry tsa lehlabathe le difeme tsa mechini di ile tsa bulwa ho etsa di-valve ka ho latellana.
Sehlopha sa tlhahiso ea li-valve se thehiloe libakeng tsa Zhonghongqiao, Waihongqiao, Daming Road le Changzhi Road Seterekeng sa Hongkou, Shanghai. Ka nako eo, lihlahisoa tse rekisoang haholo 'marakeng oa lehae e ne e le "Horse Head", "Three 8″, "Three 9″, "Double Coin", "Iron Anchor", "Chicken Ball" le "Eagle Ball". Lihlahisoa tsa li-valve tsa koporo le tšepe e lahlehileng tse nang le khatello e tlase li sebelisoa haholo bakeng sa li-valve tsa liphaephe mehahong ea kaho le ea bohloeki, 'me palo e nyane ea li-valve tsa tšepe e lahlehileng le eona e sebelisoa indastering ea masela a bobebe. Lifeme tsena li nyane haholo ka tekanyo, ka theknoloji e khutlelang morao, lisebelisoa tse bonolo tsa limela le tlhahiso e tlase ea li-valve, empa ke sebaka sa pele sa tsoalo sa indasteri ea li-valve ea Chaena. Hamorao, kamora ho theoa ha Mokhatlo oa Lisebelisoa tsa Kaho oa Shanghai, bahlahisi bana ba li-valve ba kene mokhatlong ka bonngoe 'me ba fetoha setho sa sehlopha sa metsi.
02Lifeme 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, fektheri e ile ea theha khoebo e kopanetsoeng le Xiangfeng Iron Pipe Factory le beng ba likarolo tsa Xiangtai Iron Co., Ltd. ho haha Daxin Iron Factory (e neng e le pele ho Shanghai Bicycle Factory), ka 1936. E phethiloe 'me ea kenngoa tlhahisong, ho na le basebetsi ba ka bang 100, ka zhang tse 2.6 tse tsoang kantle ho naha (zhang e le' ngoe).≈3.33m) di-lathe le disebediswa tsa ho phahamisa, haholo-holo di hlahisa disebediswa tsa indasteri le tsa merafo, diphaephe tsa metsi tsa tshepe e lahletsweng le di-valve tsa tshepe e lahletsweng, boholo bo tlwaelehileng ba valve ke NPS6 ~ NPS18, mme E ka rala le ho fana ka disete tse felletseng tsa di-valve bakeng sa dipolante tsa metsi, mme dihlahiswa di romelwa Nanjing, Hangzhou le Beijing. Kamora hore bahlasedi ba Majapane ba “La 13 Phato” ba hapile Shanghai ka 1937, boholo ba fektheri le disebediswa fekthering di ile tsa senngwa ke mollo wa dibetsa tsa Majapane. Selemong se latelang ho ile ha eketseha tjhelete mme ha qalwa mosebetsi. Di-valve tsa tshepe tse lahletsweng tsa NPS14 ~ NPS36, empa ka lebaka la ho putlama ha moruo, kgwebo e diehang, le ho kgaolwa ha mesebetsi ka lebaka la ho fokotsa tjhelete, ha di a kgona ho hlaphoheloa ho fihlela mantsiboya a ho thehwa ha New China.
Ka 1935, beng ba likarolo ba bahlano ho kenyeletsoa le Li Chenghai, rakhoebo oa naha, ba thehile hammoho Shenyang Chengfa Iron Factory (e neng e le pele ho Tieling Valve Factory) Tseleng ea Shishiwei, Setereke sa Nancheng, Motseng oa Shenyang. Lokisa le ho etsa li-valve. Ka 1939, fektheri e ile ea fallisetsoa Beierma Road, Seterekeng sa Tiexi bakeng sa katoloso, 'me li-workshop tse peli tse kholo tsa ho lahla le ho sebetsa li ile tsa hahoa. Ka 1945, e ne e se e holile ho fihlela ho basebetsi ba 400, 'me lihlahisoa tsa eona tse ka sehloohong e ne e le: liboiler tse kholo, li-valve tsa koporo tse entsoeng ka tšepe, le li-valve tsa heke ea tšepe e entsoeng ka tlas'a lefatše tse nang le boholo bo tloaelehileng bo ka tlase ho DN800. Shenyang Chengfa Iron Factory ke moetsi oa li-valve ea loanelang ho phela Chaena ea khale.
03 Indasteri ea li-valve ka morao
Nakong ea Ntoa ea Khahlanong le Majapane, likhoebo tse ngata Shanghai le libakeng tse ling li ile tsa fallela boroa-bophirima, kahoo palo ea likhoebo Chongqing le libakeng tse ling sebakeng se ka morao e ile ea eketseha, 'me indasteri ea qala ho hola. Ka 1943, Fektheri ea Mechini ea Chongqing Hongtai le Fektheri ea Mechini ea Huachang (lifektheri ka bobeli e ne e le tsa pele ho Fektheri ea Valve ea Chongqing) li ile tsa qala ho lokisa le ho etsa likarolo tsa liphaephe le li-valve tse nang le khatello e tlase, tse ileng tsa phetha karolo e kholo ho nts'etsopele ea tlhahiso ea nakong ea ntoa ka morao le ho rarolla li-valve tsa sechaba. Kamora tlholo ea Ntoa ea Khahlanong le Majapane, Fektheri ea Lisheng Hardware, Mokhatlo oa Liindasteri oa Zhenxing, Fektheri ea Hardware ea Jinshunhe le Fektheri ea Hardware ea Qiyi li ile tsa buloa ka tatellano ho hlahisa li-valve tse nyane. Kamora ho theoa ha New China, lifektheri tsena li ile tsa kopanngoa ho ba Fektheri ea Valve ea Chongqing.
Ka nako eo, ba bangbahlahisi ba li-valveShanghai le yona e ile ya ya Tianjin, Nanjing le Wuxi ho ya haha difeme tsa ho lokisa le ho etsa di-valve. Difeme tse ding tsa hardware, difeme tsa diphaephe tsa tshepe, difeme tsa mechini kapa dibaka tsa dikepe Beijing, Dalian, Changchun, Harbin, Anshan, Qingdao, Wuhan, Fuzhou le Guangzhou le tsona di bile le seabo ho lokiseng le ho hlahiseng di-valve tse ding tsa diphaephe.
