A tlangpi in
Valvecu a tlangpi in seh thilri ah a biapi mi thilri a si. Valve chung i channel area thlennak in medium a luannak uk khawhnak ding caah pipe asiloah thilri phunphun ah chiah a si. A riantuannak cu: thilri kha pehtlaih asiloah tan, thilri kha a luan tthan lonak hnga lo kham, thilri nih a chuahpimi hneknak le a luannak tibantuk parameter pawl kha remh, thilri a luannak lam kha thlen, thilri kha tthen asiloah pipeline le thilri pawl kha a hlei in a luangmi in huhphenh, tbk.
Valve thilri phunphun tampi an um, cu hna cukutka valve, vawleicung valve,check valve, ball valve,butterfly valve, plug valve, diaphragm valve, safety valve, regulating valve (control valve), throttle valve, pressure reducing valve le Traps, tbk.; Thilri ning in, dar cawhmi, thir cawhmi, carbon thir, cawhmi thir, austenitic thir, ferritic-austenitic dual-phase thir, nickel-based cawhmi, titanium cawhmi, engineering plastics le ceramic valves, tbk. ah tthen a si. le pipeline, nuclear industry caah valve, tilawng caah valve le cryogenic valve hna. Valve parameters phunphun, DN1 (mm in unit) in DN9750 tiang a ngan ning; ultra-vacuum 1 in a chuakmi hneknak× 10-10 mmHg (1mmHg = 133.322Pa) in PN14600 (105 Pa unit) a sang tukmi hneknak tiang; Riantuannak lumnak cu a niam tukmi lumnak -269 in aa thawk°C1200 tluk a sang tukmi lumnak tiang°C.
Valve thilri ramchung sipuazi riantuannak phunphun ah tam deuh in hman an si, cu hna cu chiti, natural gas, chiti le gas thianhnak le sernak le pipeline phurhnak system, chemical thilri, sii le rawl chuahnak system, ti thazaang, lumternak thazaang le nuclear thazaang chuahnak system hna an si; Valve phunphun cu lumternak le thazaang peknak system, thir sernak system, tilawng, mawtaw, vanlawng le lentecelhnak seh phunphun caah ti system, le loram caah ti thletnak le ti chuahnak system ah tampi hman a si. Cun, ralvennak le vanlawng tibantuk thiamnak thar lei ah, a hleiin thilri a ngeimi valve phunphun zong an hman.
Valve thilri hna nih hin seh thilri hna lakah a tam deuh an lak. Ramdang sipuazi a tthangchomi ram hna cazin ning in, valve chuahmi man cu seh sernak riantuannak dihlak chuahmi man 5% hrawng a si. Statistics ning in, hlanlio nuclear mei thazaang chuahnak sehzung cu kilowatt unit nuai hnih in sermi a si i, aa hrawmmi valve 28,000 hrawng a ngei, cu chung ah 12,000 hrawng cu nuclear tikulh valve an si. Chanthar a nganmi petrochemical complex nih hin valve phunphun thong tampi a herh, cun valve ah hmanmi tangka cu thilri ah hmanmi tangka dihlak i 8% in 10% tiang a si tawn.
Tuluk ram hlun ah valve riantuannak dirhmun tlangpi
01 Tuluk ram valve sernak hmun: Shanghai
Tuluk ram hlun ahcun, Shanghai cu Tuluk ram ah valve sernak hmun hmasa bik a si. 1902 ah, Pan Shunji Copper Workshop, Wuchang Lam, Hongkou District, Shanghai ah a ummi nih kut in ti kholhnak kuang hme tete ser hram a thawk. Ti dinnak kuang cu dar in sermi ar phunkhat a si. Tuluk ram ah atu tiang theihmi valve sertu hmasa bik a si. 1919 ah, Deda (Shengji) Hardware Factory (Shanghai Transmission Machinery Factory hlan i a rak ummi) cu cycle hmete in aa thawk i a hmetemi dar cock, globe valve, gate valve le meithat hydrant pawl chuah hram aa thawk. Thir valve sernak cu 1926 ah aa thawk, a tam bik NPS6 (inches in, NPS1 = DN25.4) a si. Hi caan chungah, Wang Yingqiang, Dahua, Lao Demao le Maoxu tibantuk thilri sernak sehzung hna zong nih valve sernak caah an on. Cu hnu ah, market ah ti luhchuahnak valve a herhnak a karh caah, thilri sernak sehzung, thir sehzung, thetse sernak sehzung le seh sernak sehzung hna cu pakhat hnu pakhat in valve sernak caah an hun.
Shanghai, Hongkou pengkulh Zhonghongqiao, Waihongqiao, Daming lam le Changzhi lam hna ah valve sernak phu pakhat dirh a si. Cu lio ahcun, ramchung chawlehnak ah a zuar bikmi thilri pawl cu “Rang Lu”, “Pathum 8′′, “Pathum 9′′, “Double Coin”, “Iron Anchor”, “Chicken Ball” le “Eagle Ball” an si. A tlawmmi dar le thir valve thilri hna cu inn saknak le thianhlimnak hmun ah ti luhchuahnak valve caah hman a si bik, cun thir valve tlawmpal cu thilthuam tlawmte sernak lei zongah hman a si. Hi sehzung hna hi an hmete tuk, hnulei ah a ummi thiamnak, sehzung thilri sawhsawh le valve chuahmi a tlawmmi an si, asinain Tuluk valve industry a chuahkehnak hmun hmasa bik an si. A hnu ah, Shanghai Construction Hardware Association dirh a si hnu ah, hi valve sertu hna nih bu ah pakhat hnu pakhat an i tel i ti lam phu ah an cang. chungtel.
02Valve sernak sehzung nganpi pahnih
1930 kum hramthawk ah, Shanghai Shenhe Machinery Factory nih ti riantuannak caah NPS12 tang ah a niam deuhmi thir kutka valve a ser. 1935 ah, sehzung nih Xiangfeng Thir Pipe Sehzung le Xiangtai Thir Co., Ltd. share ngeitu hna he Daxin Thir Sehzung (Shanghai Cycle Sehzung hlan i a rak ummi) saknak ding caah riantuan ttinak an dirh, 1936 ah an lim i chuah hram an thawk, riantuantu 1000 hrawng an um i, ramdang in luhpi mi zhang (2612) an um.≈3.33m) lathes le lifting thilri, a bik in riantuannak le lungmeihol chuahnak thilri, thir ti pipe le thir valve, valve a ngan ning cu NPS6 ~ NPS18 a si, cun ti sernak sehzung caah valve set tling tein a suai khawh i a pek khawh, cun thilri pawl cu Nanjing, Hangzhoung le Beijing ah kuat an si. “August 13′′ Japan ralkap nih 1937 ah Shanghai an lak hnu ah, sehzung chung i sehzung le thilri tam deuh cu Japan meithal kahnak nih a hrawh hna. A hnu kum ah tangka a karh i rian a thawk tthan. NPS14 ~ NPS36 thir kutka valves, asinain sipuazi tlaknak, a tlawmmi chawlehnak le rian dinhternak ruangah an si kho ti lo Tuluk ram thar dirh ni hlan tiang damter than ding.
1935 ah, ram pumpi chawlettu Li Chenghai telh in share ngeitu panga nih Shenyang khuapi, Nancheng peng, Shishiwei lam ah Shenyang Chengfa thir sehzung (Tieling Valve sehzung hlan i a rak ummi) kha hmunkhat ah an dirh. Valve remh le ser. 1939 ah, sehzung cu Beierma Lam, Tiexi Peng ah kauhternak caah an ṭhial i, thil sernak le seh sernak caah rianṭuannak hmun nganpi pahnih an sak. 1945 ah, riantuantu 400 tiang a karh, cun a thilchuak bik cu: a nganmi lumternak seh, dar in sermi valve, le vawlei tang thir in sermi kutka valve hna cu DN800 tang ah a ummi an si. Shenyang Chengfa thir sernak sehzung cu Tuluk ram hlun ah nun khawhnak ding caah aa zuammi valve sernak sehzung a si.
03Hnulei ah valve riantuannak
Japan dohnak ral lio ah, Shanghai le hmun dangdang ah chawlehthalnak tampi cu nitlak thlanglei ah an i thial, cucaah Chongqing le a hnulei hmun dangdang ah chawlehthalnak an karh tuk caah, chawlehnak cu a thangcho. 1943 ah, Chongqing Hongtai Machinery Factory le Huachang Machinery Factory (sehzung pahnih ningin Chongqing Valve Factory hlan i an rak si) nih ti chuahnak thilri le low-pressure valve pawl remh le ser hram an thawk, cu nih cun hnulei valve le civilian valve pawl ah ral lio thilchuah khawhnak ah hmunhma nganpi a lak. Japan dohnak ral ah teinak an hmuh hnu ah, Lisheng Hardware Factory, Zhenxing Industrial Society, Jinshunhe Hardware Factory le Qiyi Hardware Factory hna cu a hnu hnu in valve hmete chuah khawhnak ding caah an hun. Tuluk ram thar an dirh hnu ah, hi sehzung hna cu Chongqing Valve Factory ah an fonh hna.
Cu lio ahcun, cheukhatvalve sertu hnaShanghai zongah Tianjin, Nanjing le Wuxi ah valve remh le sernak sehzung saknak ah a kal. Beijing, Dalian, Changchun, Harbin, Anshan, Qingdao, Wuhan, Fuzhou le Guangzhou ah a ummi thilri sernak sehzung cheukhat, thir hri sernak sehzung, sehzung cheukhat asiloah tilawng sernak sehzung hna zong nih ti luhchuahnak valve cheukhat remhnak le sernak ah an i tel ve.
