Lembe mukadho pa dongo pa tic mi valve mi China (1)

Neno wi lembe

Valveubedo piny ma pire tek i tic mi cuma. Jukethe iwi paip matung tung nyo jam tic matung tung pi jwigo mol pa pii ni loko kabedo pa pii ma mol i valve. Tic pare utiye: mako nyo poko piny ma ikin piny, juku piny ma i iye kud udok cen, loko piny ma iye calu tegu pa piny ma iye man mol pa piny, loko yo pa piny ma iye, poko piny ma iye nyo gwoko pipelines man jam tic kud i tegu ma lee, man mange.

Tye kit piny madwong ma juyubu ku valve, ma jupoko ivalve mi dhugola, globe valve,check valve, ball valve,butterfly valve, plug valve, diaphragm valve, safety valve, regulating valve (control valve), throttle valve, pressure reducing valve and Traps, etc.; Nimakere ku piny ma jutiyo kudu, jupoko i copper alloy, cast iron, carbon steel, alloy steel, austenitic steel, ferritic-austenitic dual-phase steel, nickel-based alloy, titanium alloy, engineering plastics man ceramic valves, man mange. Mi medo, nitie valves ma pire tek calu ultra-high pressure valves, vacu valves, valves pi pipeline valves man pipelines, valves pi tic mi nuclear, valves pi meli man cryogenic valves. Kit valve mapol, dit pa DN1 (unit in mm) ni DN9750; kero ma nok kud i ultra-vacuum pa 1× 10-10 mmHg (1mmHg = 133.322Pa) ni ultra-high pressure pa PN14600 (unit pa 105 Pa); Lieth pa tic ucaku ikum lyethu ma piny pa -269°Cni rwom ma malu pa 1200°C.

Piny pa Valve jutiyu kudu lee i thenge matung tung mi ngom, calu oil, natural gas, oil man gas ma juyubu man yub pa pipeline, piny ma juyubu ku kemikol, yore mi yubu yath man cam, kero mi pii, kero mi lyethu man yore mi yubu kero mi nuclear; Kit valve matung tung jutiyu kudu lee i yore mi lyethu man mi mio mac, yore mi yubu cuma, yore mi pii pi yei, mutukari, ndege man cuma mi tugu matung tung, man yore mi poko pii man pii ma mol i ngom mi fur. Mi medo, i thenge mi diro manyen calu ve gwoko kuc man aerospace, jutiyo ku valve matung tung ku kite ma pire tek.

Piny ma juyubu ku valve uketho dul madit pa piny ma juyubu ku cuma. Ni lubre ku wel mi ngom ma woko ma dongo dongo, wel ma wok kud i valves ubedo 5% pa wel ma wok kud i tic mi cuma. Ni lubre ku wel, kabedo macon mi kero pa nuclear ma romo kilowatt million aryo utiye ku 28,000 valves ma jupoko, ma romo 12,000 utiye nuclear island valves. Kabedo madit mi petrochemical ma kawoni mitu valve mapol matung tung, man lim ma jutiyo kudu pi valve ubedo 8% ku 10% pa lim ma jutiyo kudu pi jam tic.

Kite ma tic mi valve ubedo kudu i China macon

01 Kabedo mi nyol pa tic mi valve mi China: Shanghai

I China macon, Shanghai ubedu kabedu mir acel mi yubu valve i China. I 1902, Pan Shunji Copper Workshop, ma nwangire i Wuchang Road, Hongkou District, Shanghai, ucaku yiku dul ma nok pa teapot faucets ku cing. Teapot faucet ubedo kit copper moko ma jucwalo. Etiye jayub valve mir acel i China ma jung'eyo nitundu kawoni. I 1919, Deda (Shengji) Hardware Factory (m'utelo wi Shanghai Transmission Machinery Factory) ucaku ku gari ma nok man ucaku yubu copper cocks, globe valves, gate valves man fire hydrants. Yubu pa valve mi cuma ucaku i 1926, ku dit pa NPS6 (i inches, NPS1 = DN25.4). I kind kare eni, ka yubu piny macalo Wang Yingqiang, Dahua, Lao Demao man Maoxu de oyabere pi yubu valve. I ngeye, pi mediri pa yeny pa valve mi pii i soko, dul mange mi factory mi jam tic, factory mi cuma, factory mi sand foundry (casting) man factory mi cuma oyabere pi yiku valve acel acel.

Udul mi yiku valve juyike i kabedo mi Zhonghongqiao, Waihongqiao, Daming Road man Changzhi Road i Hongkou District, Shanghai. I kare meno, piny ma jucwalo maber uloyu i soko mi ng'om ubedo "Horse Head", "Three 8", "Three 9", "Double Coin", "Iron Anchor", "Chicken Ball" man "Eagle Ball". Low-pressure cast copper man cast iron valve products pol kare jutiyo kudu pi plumbing valves i ot man kabedo mi gwoko leng pa kum, man cast iron valves manok de jutiyo kudu i light textile industry industry. Factory eni gi nok mandha, ku diro ma rwinyo, jam tic ma yot man valve ma nok, ento gi ubedo kabedu ma kwong mi tic mi valve i China. I ngeye, ingey yik pa Shanghai Construction Hardware Association, ju ma yiku valve gimondo i dul ne acel acel man gidoko dul pa pii. jatel wi dhanu.

02Kabedo ario madongo mi yiku valve

I acaki pa 1930, Shanghai Shenhe Machinery Factory utimo low-pressure cast iron gate valves piny pa NPS12 pi tic mi pii. I 1935, factory ne ucaku tic karacelu ku Xiangfeng Iron Pipe Factory man Xiangtai Iron Co., Ltd. ju ma gi julonyo pi gier Daxin Iron Factory (m'utelo wi Shanghai Bicycle Factory), i 1936 Judaru man jukethe i tic, jurutic 100, ku 26 zhang ma jukelo kudi ngom mange.≈3.33m) lathes man jam tic mi tingo piny, ma pol kare juyubu piny mi tic man mining, paip mi pii ma juyubu ku cuma man valve mi cuma, dit pa valve utiye NPS6 ~ NPS18, man ecopu yubu man mio valve mapol pi kabedo mi pii, man piny ne jucwalo i Nanjing, Hangzhoung man Beijing. I ngei "Nindo 13 mi dwi mir abora", ju Japan ma gimondo i Shanghai i 1937, pol pa cuma man jam tic i factory ne unyothere ku mac pa Japan. I oro mukende, jumedo lim man jucaku tic kendu. NPS14 ~ NPS36 cast iron gate valves, ento pi can pa lim, tic ma nok, man weko tic, gibedo ngo maber ni dwoko piny nitundu ikare ma jucaku kudu New China.

I 1935, juwil piny abic ikinde Li Chenghai, jalonyo mi ngom, gicaku Shenyang Chengfa Iron Factory (ma ubedo Tieling Valve Factory ma kwong) i Shishiwei Road, Nancheng District, Shenyang City. Yub man yiku valves. I 1939, judwoko factory ne i Beierma Road, Tiexi District pi medo, man jugiero kabedo ario madongo mi tic ku jam tic. I 1945, edongo ni jurutic 400, man piny pare madit ubedu: boilers madongo, valves mi copper, man valves mi cast iron ma piny ma dit migi tiye piny pa DN800. Shenyang Chengfa Iron Factory ubedo ka yubu valve ma ube temo kwo i China macon.

03Jutic mi valve in the rear

I kare mi lwiny ikum Japan, kampuni madwong i Shanghai man kabedo mange gicidho yo piny yo reto, ci wel kampuni i Chongqing man kabedo mange i ngeye umedere, man tic ne ucaku dongo. I 1943, Chongqing Hongtai Machinery Factory man Huachang Machinery Factory (factory ario zoo ubedu macon pa Chongqing Valve Factory) ucaku yiko man yiku jam tic mi pii man valve ma rwom pare lapiny, ma ukelo tic madit i dongo pa tic mi kare mi lwiny i ngeye man mi cobo peko pa dhanu. I ngei loyo lwiny mi lwiny ikum Japan, Lisheng Hardware Factory, Zhenxing Industrial Society, Jinshunhe Hardware Factory man Qiyi Hardware Factory ugam oyabere pi yubu valve ma nok. I ngei yik pa New China, juyike kabedo eni i Chongqing Valve Factory.

I saa maeca, jumokoju ma yiku valveI Shanghai de ucidho i Tianjin, Nanjing man Wuxi pi gieru ka yiku man yiku valve. Ka yubu piny moko, ka yubu paip mi cuma, ka yubu cuma nyo ka yubu yei i Beijing, Dalian, Changchun, Harbin, Anshan, Qingdao, Wuhan, Fuzhou man Guangzhou de gibedu ka yubu man yubu valve moko mi pii.
