Ukucubungula
Isivalwanangumkhiqizo obalulekile emishini ejwayelekile. Ifakwe kumapayipi ahlukahlukene noma kumadivayisi ukulawula ukuhamba kwe-Medium ngokushintsha indawo yesiteshi kwi-valve. Imisebenzi yayo yile: Xhuma noma unqume okuphakathi, vimbela okuphakathi kusuka emuva, lungisa amapharamitha anjengengcindezi ephakathi nendawo, shintsha indlela yokugeleza okuphakathi, njyela amapayipi nemishini kusuka ekucindezelweni ngokweqile, njll.
Kunezinhlobonhlobo eziningi zemikhiqizo ye-valve, ehlukanisweI-SAGE VALVVVE, i-valve yomhlaba,Bheka i-valve, ibhola valve,I-butterfly valve, i-valve ye-plug, i-valve ye-diaphragm, i-valve yokuphepha, ukulawula i-valve (i-valve yokulawula), i-throttle valve, ingcindezi yehlisa i-valve kanye nezicupho, njll. Ngokusho kwezinto ezibonakalayo, ihlukaniswe nge-post alloy, i-carbon iron, i-carbon yensimbi, i-aorditic-auntenitutic, i-alloy ye-allves, ama-talves aphezulu, ama-talves aphezulu, ama-valves aphezulu, ama-valves ama-pipelines futhi Amapayipi, ama-valve emboni yenuzi, ama-valves wemikhumbi nama-cryogenic valves. Uhla olubanzi lwamapharamitha we-valve, usayizi ogama kusuka ku-DN1 (unit ku-MM) ku-DN9750; Ingcindezi efingqiwe evela ku-Ultra-Vacuum ye-1× I-10-10 mmhg (1mmhg = 133.322PA) ekucindezelweni kwe-PN14600 (iyunithi le-105 pa); Izinga lokushisa elisebenzayo lisuka ekushiseni okuphansi okuphansi kwe--269℃ekushiseni okuphezulu okuphezulu kwe-1200℃.
Imikhiqizo ye-Valve asetshenziswa kabanzi emikhakheni ehlukahlukene yomnotho wezwe, njengamafutha, igesi yemvelo, amafutha kanye nezinhlelo zokuhamba zegesi kanye nePiperaceine zokuhamba, ama-hydropower, amandla okukhiqiza amakhemikhali kanye nezinhlelo zokukhiqiza amakhemikhali; Izinhlobo ezahlukahlukene zama-valves zisetshenziswa kabanzi ezinhlelweni zokushisa nezinhlelo zokukhiqiza ama-metallurgical, amasistimu omanzi wemikhumbi, izimoto, izindiza nemishini yezemidlalo ehlukahlukene, kanye nokunisela nezinhlelo zokunisela kanye nokunisela nezinhlelo zokunisela nezinhlelo zokunisela nezinhlelo zokunisela nezinhlelo zokunisela nezinhlelo zokunisela nezinhlelo zokunisela nezinhlelo zokunisela nezinhlelo zokunisela nezinhlelo zokunisela nezinhlelo zokunisela nezinhlelo zokunisela ze-Fradul. Ngaphezu kwalokho, emikhakheni yobuchwepheshe obusha njengokuvikela kanye ne-aerospace, ama-valves ahlukahlukene anezakhiwo ezikhethekile ayasetshenziswa.
I-Akhawunti yemikhiqizo ye-Valve ngengxenye enkulu yemikhiqizo emishini. Ngokwezibalo zamazwe akwamanye amazwe athuthukile, inani lokukhipha lama-valves ama-5% enani lokukhipha lomkhakha wemishini. Ngokusho kwezibalo, isitshalo samandla entshiseko senuzi esakhiwa ama-geowatt ezigidi ezimbili sinamavalve angama-28,000 okwabiwe, kwazo cishe ama-12,000 angama-valve angama-nuclear asland. I-petrochemical yanamuhla ye-petrochemical idinga amakhulu ezinkulungwane zama-valves ahlukahlukene, kanye nokutshalwa kwezimali kuma-valves ngokuvamile ama-8% kuya ku-10% wokutshala imali okuphelele kwemishini.
Isimo esijwayelekile somkhakha wama-valve e-Old China
01 Indawo yokuzalwa embonini ye-valve yaseChina: Shanghai
E-China yakudala, kwaseShanghai kwakuyindawo yokuqala yokwenza ama-valve eChina. Ngo-1902, i-Pan Shunji Copper Workshop, etholakala eWuchang Road, eDongkou esifundeni, eShanghai, yaqala ukukhiqiza ama-batch amancane ama-teapot faucets ngesandla. I-Teapot Faucet uhlobo lwe-cast Copper comp. Kungumkhiqizi we-valve wokuqala eChina owaziwa kuze kube manje. Ngo-1919, i-Deda (Shengji) i-Hardware Factory (eyandulela imishini yokudlulisela imishini yaseShanghai) yaqala ngebhayisekili elincane futhi yaqala ukukhiqiza ama-cocks amancane ama-comples, ama-valves omhlaba, ama-valves ama-hydrate. Ukwenziwa kwama-iron valves aqala ngo-1926, ngosayizi omkhulu we-NPS6 (kuma-Iches, NPS1 = DN25.4). Ngalesi sikhathi, amafektri we-Hardware anjengeWang Yingqiang, Dahua, uLao Demao noMaoous baphinde bavula ama-valve. Kamuva, ngenxa yokwanda kwesidingo sama-valves amapayipi emakethe, elinye i-batch of fafectories ye-hardware, amafektri ensimbi, amafektri e-sandry areny (ukusakaza) avulwe ukukhiqiza ama-valve.
Kwakhiwa iqembu le-valve ezindaweni zaseZhonghongQiao, WaihongQiao, ediliza umgwaqo kanye no-Changzhi Road eHongkou District, eShanghai. Ngaleso sikhathi, imikhiqizo ethengiswa kakhulu emakethe yasekhaya yayithi "inhloko yamahhashi", "ezintathu 8", "ezintathu zensimbi", "i-anchor ephindwe kabili", "I-Iron Anchor", "Ibhola Lenkukhu" kanye "ne-Eagle Ball". I-Low-Pressure Cost Prepper kanye nemikhiqizo ye-Iron Valve isetshenziselwa ama-valves amapayipi ekwakheni nasezindaweni zokuhlanzeka, kanti inani elincane lama-cast ama-iron valves asetshenziswa emkhakheni wezimboni ezikhanyayo. Lawa mafektri amancane kakhulu esikalini, ngobuchwepheshe emuva emuva, imishini yezitshalo elula kanye nokukhipha okuphansi kwe-valve, kepha yindawo yokuqala yokuzalwa kwemboni ye-valve yaseChina. Kamuva, ngemuva kokusungulwa kweShanghai Construction Hardware Association, laba bakhiqizi be-valve bajoyine le nhlangano ngokulandelana futhi baba yiqembu lamanzi. Ilungu.
I-02TWO ENGCONO EBONAKALAYO ZOKUGCINA IZIMALI
Ekuqaleni kuka-1930, uShanghai Shenhe Imishini Yefekthri akhiqizwa ama-value we-Iron-Iron Cression ephansi ye-NPS12 ngaphansi kwemisebenzi yamanzi. Ngo-1935, ifektri yasungula i-ventini ehlanganyelwe nge-Xiangfeng Iron Pipe Factory kanye ne-Xiangtai Iron Co, Ltd. Amasheya wamasheya wokwakha i-Daxin Iron Chores (ngo-1936 aqediwe, acishe abe yizisebenzi eziyi-100, ane-zhang engenisiwe (1 Zhang≈3.33m) Ukulahla kanye nokuphakamisa imishini, ikakhulukazi ukukhiqiza izesekeli zezimboni nezokumbiwa phansi, amapayipi e-Iron wamanzi kanye nama-valve ama-valve, futhi kungahle ukuklama ama-nanjing, i-hangzhou neBeijing. Ngemuva kwe "Agasti 13" Abahlaseli BaseJapan bahlala eShanghai ngo-1937, iningi lesitshalo nemishini efektri babhujiswa ngumlilo we-artillery aphilisi waseJapan. Ngonyaka olandelayo wandisa imali enkulu futhi waqala kabusha. I-NPS14 ~ NPS36 I-Iron Iron Galog valves, kepha ngenxa yokudangala kwezomnotho, ibhizinisi elivilaphayo, kanye nama-austerity i-layoffs, abakwazanga ukululama kuze kube yilapho u-Eva yokusungulwa kweNew China.
Ngo-1935, abanikazi bamasheya abahlanu kubandakanya uLi Chenghai, usomabhizinisi kazwelonke, asungulwe ngokuhlanganyela uShenyang Chengfa Iron Factory (umsunguli we-veling valve) kwiShishiwei Road, esifundeni saseShenyang, eShenyang City. Ukulungisa nokwenza ama-valve. Ngo-1939, leli Factory lathuthelwa eBeierma Road, isifunda se-Tiexi ekwandisweni, kwakhiwa ama-workshop amabili emijondolo emibili yokuphonsa kanye nemishini. Ngo-1945, yayikhule yabasebenzi abangama-400, futhi imikhiqizo yayo eyinhloko ibi: I-Shenyang Chengfa Iron Factory ngumkhiqizi we-valve elwa nobunzima bokusinda eChina yakudala.
Imboni ye-03 Imboni ye-valve ngemuva
Ngesikhathi sempi ye-anti-Japanese, amabhizinisi amaningi eShanghai nakwezinye izindawo athuthela eningizimu-ntshonalanga, ngakho-ke inani lamabhizinisi eChongqing nezinye izindawo ezakhiwe zanda, futhi imboni yaqala ukuthuthuka. Ngo-1943, amakhekheli emishini yaseHongtaing Hongtaing kanye ne-Huachang Michch Pactory (womabili lawo mafektri ayengaphambi kwawo efektri yama-chongqing valve) aqala ukulungisa futhi akhiqize indima enkulu ekwakheni ukukhiqizwa kwempi ngemuva nasekuxazululeni ama-valve ebusuku. Ngemuva kokunqoba kwempi ye-anti-Japanese, ifektri yehadiwe ye-libeng, i-Zhenxing Industrial Inhlangano, i-JinShwenherware Factory kanye ne-Qiyi Hardware Factory evule ngempumelelo ukukhiqiza ama-valve amancanyana. Ngemuva kokusungulwa kweNew China, la mafektri ahlanganiswa abe yimboni ye-chongqing valve.
Ngaleso sikhathi, ezinyeAbakhiqizi be-ValveEShanghai nakho kwaya eTianjin, eNanjing kanye ne-WUXI ukwakha amafektri ukulungisa nokwenza ama-valve. Amanye amafektri we-Hardware, amafektri e-Iron Pipe, amafektri wemishini noma ama-Shipching eBeijing, Dalian, Changchun, Harbin, Wuhan, Fuzhou noGuangzhou baphinde bakhiqiza ama-valves.
