Balbulametung yang importanting produktu keng pangkabilugan a makinarya. Iti maka-install ya kareng miyayaliwang pipe o devices para makontrol ing daloy ning medium kapamilatan ning pamagbayu keng channel area keng valve. Deng kayang obra ilapin deng: ikonekta o pututan ing medium, pigilan ing medium a mamagus pabalik, i-adjust ing parameters antimo ing medium pressure ampong flow, alilan ing direksyun ning danum ning medium, pipartian ne ing medium o protektan la reng pipeline ampong kasangkapan ibat king overpressure, atbp.
Dakal la reng uri da reng produktung balbula, a makadake karenggate valve, globe valve,check valve, ball valve,balbula ning parul, plug valve, diaphragm valve, safety valve, regulating valve (control valve), throttle valve, pressure reducing valve ampo Traps, atbp.; Agpang keng materyales, mepitna ya keng copper alloy, cast iron, carbon steel, alloy steel, austenitic steel, ferritic-austenitic dual-phase steel, nickel-based alloy, titanium alloy, engineering plastics ampo ceramic valves, atbp. Dagdag pa, atin yang espesyal a valves antimo reng ultra-high pressure valves, vacuum valves, powerline valves para kareng pipeline valves ampo pipelines, valves para keng nuclear industry, valves para kareng barko ampo cryogenic valves. Malawak a range ning valve parameters, nominal size manibat DN1 (unit in mm) angga DN9750; nominal pressure ibat keng ultra-vacuum ning 1× 10-10 mmHg (1mmHg = 133.322Pa) keng ultra-high pressure ning PN14600 (unit ning 105 Pa); Ing temperatura ning obra manibat ya keng ultra-low temperature a -269°Ckeng matas a temperatura ning 1200°C.
Produktu ning balbula maralas lang magagamit kareng miyayaliwang sektor ning pambansang ekonomiya, antimo ing langis, natural a gas, pamagdalisay ampong pamagprosesu king langis ampong gas ampong sistema ning pamagdala king pipeline, produktung kemikal, sistema ning pamaglalang parmasyutika ampong pamangan, sistema ning pamaglalang king enerhiya ning pali ampong nuclear power; Deng miyayaliwang uri da reng balbula maralas lang magagamit keng heating ampo power supply systems, metalurgical production systems, fluid systems para kareng barko, saken, eroplanu ampo miyayaliwang sports machinery, ampo irrigation ampo drainage systems para keng gabun. Dagdag pa, kareng larangan da reng bayung teknolohiya antimo ing depensa ampong aerospace, miyayaliwang balbula a maki espesyal a katangian ing gagamitan da.
Deng produktung valve ila reng maragul a dake da reng produktung mekanikal. Agpang keng statistics da reng dayu a industrialisadung bangsa, ing output value da reng balbula mag-account ya keng 5% ning output value ning mabilug a industriya ning makinarya. Agpang keng statistics, ing metung a tradisyunal a nuclear power plant a bibilugan da reng adwang milyung kilowatt units atin yang mga 28,000 a shared valves, nung nu mga 12,000 kareti ila reng nuclear island valves. Ing modernung maragul a petrochemical complex mangailangan yang dinalan a libung miyayaliwang balbula, at ing puhunan kareng balbula keraklan mag-account yang 8% anggang 10% ning kabilugan a puhunan kareng kasangkapan.
pangkabilugan a sitwasyun ning industriya ning balbula keng matwang china
01 Ing pibatan ning industriya ning balbula ning Tsina: Shanghai
keng matuang china, ing shanghai ing mumunang lugal na gagawang balbula keng china. Inyang 1902, ing Pan Shunji Copper Workshop, atyu keng Wuchang Road, Hongkou District, Shanghai, megumpisa yang ginawang mangalating batch da reng teapot faucets gamit ing gamat. Ing teapot faucet metung yang uri ning cast copper cock. Iti ing minunang gagawang balbula keng china a balu da angga ngeni. Inyang 1919, ing Deda (Shengji) Hardware Factory (ing minunang Shanghai Transmission Machinery Factory) megumpisa ya keng malating bisikleta at megumpisa yang ginawang malating diameter a copper cocks, globe valves, gate valves ampo fire hydrants. Ing pamaglalang kareng cast iron valves megumpisa ya inyang 1926, a maki maximum a sukad a NPS6 (keng pulgada, NPS1 = DN25.4). Ketang panaun a ita, ding pabrika ning hardware antimo reng Wang Yingqiang, Dahua, Lao Demao ampo ing Maoxu mibuklat la para gawang balbula. Kaybat, pauli ning pamagtas ning pamangailangan kareng balbula ning pipa keng palengki, metung pang batch da reng pabrika ning hardware, pabrika ning bakal, pabrika ning sand foundry (casting) ampo pabrika ning makina ing mibuklat para gawang balbula ing metung kaybat ning metung.
Metung a grupung gagawang balbula ing mebuu kareng lugal ning Zhonghongqiao, Waihongqiao, Daming Road ampo Changzhi Road keng Hongkou District, Shanghai. Kanita, deng pekamasanting a tatak keng domestic market ilapin deng "Horse Head", "Three 8", "Three 9", "Double Coin", "Iron Anchor", "Chicken Ball" ampo "Eagle Ball". Deng low-pressure cast copper ampo cast iron valve products keraklan gagamitan da la para kareng plumbing valves kareng gusali ampo sanitary facilities, ampo ditak a cast iron valves magagamit la naman keng light textile industry sector. Deng pabrika a reni malati la mu, atin lang backward a teknolohiya, simpleng kasangkapan keng planta ampo mababang valve output, pero ila reng minunang pibatan ning valve industry ning china. Kaybat, kaybat ning pangatatag ning Shanghai Construction Hardware Association, deng gagawang balbula mekiabe la keng asosasyun metung kaybat ning metung at meging grupu da reng waterway. miyembru.
02Adwa lang maragul a planta ning pamaglalang balbula
keng umpisa ning 1930, ing Shanghai Shenhe Machinery Factory ginawa yang low-pressure cast iron gate valves lalam ning NPS12 para keng obra keng danum. Inyang 1935, ing pabrika mitatag yang joint venture kareng Xiangfeng Iron Pipe Factory ampo Xiangtai Iron Co., Ltd. shareholders para gawan ing Daxin Iron Factory (ing minunang Shanghai Bicycle Factory), inyang 1936 Meyari ya at milub keng produksyun, atin yang halus 1000 a empleyadu, a maki import a zhang (26 zhang).≈3.33m) lathes ampo lifting equipment, keraklan gagawang industrial ampo mining accessories, cast iron water pipes ampo cast iron valves, ing nominal size ning valve yapin ing NPS6 ~ NPS18, ampo malyari yang magdesign ampo magsupply kumpletung set da reng valves para kareng water plants, ampo deng produktu mi-export la keng Nanjing, Hangzhoung ampo Beijing. Kaybat ning “August 13′′ a sinakup da reng Japanese invaders ing Shanghai inyang 1937, keraklan kareng planta ampo kasangkapan keng pabrika mesira la keng Japanese artillery fire. Ing tutuking banua meragdagan ing capital ampo mibalik ing obra. NPS14 ~ NPS36 cast iron gate valves, pero pauli ning economic depression, mabagal a negosyu, ampo ing pamaglayoff, e la mesira bang mibawi angga king bisperas ning pangatatag ning Bayung Tsina.
Inyang 1935, limang shareholders kayabe ya i Li Chenghai, metung a pambansang negosyanti, miyabe-abe lang mitatag king Shenyang Chengfa Iron Factory (ing minunang Tieling Valve Factory) king Shishiwei Road, Nancheng District, Shenyang City. Ayus at gawa kang balbula. Inyang 1939, linipat de ing pabrika king Beierma Road, Distritu ning Tiexi para king pamagpalawak, at mitalakad lang aduang maragul a talyer para king pamag-cast ampong pamag-machine. Inyang 1945, miras yang 400 a empleyadu, at deng peka-produktu na ilapin deng: mangaragul a boiler, cast copper valves, ampong underground cast iron gate valves a maki nominal a sukad lalam ning DN800. Ing Shenyang Chengfa Iron Factory metung yang valve manufacturer na mag struggle para mabye keng matwang China.
03Ing industriya ning balbula keng gulut
Anyang Anti-Japanese War, dakal a negosyu keng Shanghai ampo kareng aliwang lugal ing miglakbe keng maulingalbugan, inya ing bilang da reng negosyu keng Chongqing ampo kareng aliwang lugal keng gulut a lugal meragul ya, ampo ing industria megumpisa yang miunlad. Inyang 1943, ing Chongqing Hongtai Machinery Factory ampo ing Huachang Machinery Factory (parehu lang pabrika deng minunang pabrika ning Chongqing Valve Factory) megumpisa lang mig-repair ampo mig-manufacture kareng plumbing parts ampo kareng low-pressure valves, na mika maragul a papil keng pamaglalang keng gera keng gulut ampo keng pamaglutas kareng civilian valves. Kaybat ning tagumpe ning Anti-Japanese War, ing Lisheng Hardware Factory, Zhenxing Industrial Society, Jinshunhe Hardware Factory ampo ing Qiyi Hardware Factory mibuklat la para gawang mangalating balbula. Kaybat ning pangatatag ning Bayung Tsina, deting pabrika misasanmetung la king Chongqing Valve Factory.
Kanita, atingagawang balbulakeng Shanghai minta ya naman keng Tianjin, Nanjing ampo Wuxi para gawang pabrika para mag-ayus ampo gawang balbula. Deng mapilan a pabrika ning hardware, pabrika ning bakal a pipa, pabrika ning makina o shipyard king Beijing, Dalian, Changchun, Harbin, Anshan, Qingdao, Wuhan, Fuzhou ampo Guangzhou ila ring makiabe king pamag-ayus at pamaglalang kareng mapilan a balbula ning pipa.
