Incamake

Valvenigicuruzwa cyingenzi muri mashini rusange. Ishyirwaho kumiyoboro itandukanye cyangwa ibikoresho kugirango igenzure uburyo bwo hagati muguhindura umuyoboro muri valve. Imikorere yayo ni: Guhuza cyangwa kugabanya uburyo, irinde uburyo bwo gutera inyuma, guhindura ibipimo nkibisanzwe cyangwa bihindura icyerekezo cyo hagati cyangwa kurinda imiyoboro n'ibikoresho byo hejuru, nibindi

Hariho ubwoko bwinshi bwibicuruzwa bya valve, bigabanyijemoIrembo, Globe Valve,Reba Valve, valve y'umupira,ikinyugunyugu, gucomeka valve, varaphragm, valve yumutekano, kugenzura valve (kugenzura valve), valtle ya valve, igituba gigabanya valve numutego, nibindi .; Ukurikije ibikoresho, igabanijwemo ubugome, ibyuma, Alloy Steel, Indangagaciro Zidasanzwe, Imyanya ya Cyiza na pipeline, guhanagura inganda za kirimbuzi, vanga amato na clogenic valves. Umubare munini wa valve, ingano yizina kuva dn1 (igice muri mm) kugeza dn9750; igitutu cyizina kuva ultra-vacuum ya 1× 10-10 mmhg (1Mhhg = 133.322pa) Kuvangaza umuvuduko wa PN14600 (Igice cya 105 P); Ubushyuhe bwakazi buva mu bushyuhe bwa ultra-buke bwa -269℃ku bushyuhe bwa ultra-bushyuhe bwa 1200℃.

Ibicuruzwa Byakoreshejwe cyane mu nzego zitandukanye z'ubukungu bw'igihugu, nka peteroli, gaze karemano, uburyo bwo gutunganya amavuta na gaze, imiti ifite imiti, hyrmasil na sisitemu y'umusaruro na sisitemu y'umusaruro; Ubwoko butandukanye bwa Valves bukoreshwa cyane muri sisitemu yo gutanga amashanyarazi, sisitemu yo gutanga amashanyarazi, sisitemu yamazi y'amazi, ibinyabiziga, imashini zikoresha siporo, no kuhira hamwe na sisitemu yo kuhira hamwe na sisitemu yo kuvoma na sisitemu yo kuvoma no kuvoma no kuvoma kwa sisitemu. Mubyongeyeho, mubijyanye nikoranabuhanga rishya nko kwirwanaho na Aeropace, valve zitandukanye zifite imitungo yihariye nayo irakoreshwa.

Konti y'ibicuruzwa bya Valve kubipimo binini byibicuruzwa bya mashini. Dukurikije imibare y'ibihugu by'amahanga byateye imbere mu mahanga byateye imbere, umusaruro wa Valves konti zigera kuri 5% y'agaciro k'inganda zose. Dukurikije imibare, igihingwa cy'amashanyarazi gakondo kigizwe n'amashanyarazi agizwe na miliyoni ebyiri za Kilowatt ifite impaso 28.000 zasangiye, muri zo zigera ku 12.000 zirwanira ku kirwa cya kirimbuzi. Ingofero nini nini ya peteroli isaba imirongo ibihumbi amagana, kandi ishoramari ryabereye muri rusange kuri 8% kugeza 10% by'ishoramari ryose mu bikoresho.

Ibihe rusange by'inganda za Valve mu Bushinwa

01 Uruganda ruvuvu rwinganda zubushinwa: Shanghai

Mu Bushinwa bwa kera, Shanghai nicyo cya mbere cyo gukora indangagaciro mu Bushinwa. Mu 1902, Pan Shunji Coanthop, iherereye ku muhanda wa Wuchang, Akarere ka Hongkou, yatangiye gukora ibice bito bya waogets mu ntoki. Umuyoboro wa icyayi ni ubwoko bwinkoko yumuringa. Numuco wa kera cyane mubushinwa uzwi kugeza ubu. Mu 1919, Deda (Pregos ya Produbry Uruganda rukora imashini ya Shanghai) yatangiriye ku igare rito kandi batangira kubyara amakagare mato, Globe Ikirangantego cy'umuringa, Globe Ikiranga, Irembo rihanamye n'umuriro. Gukora Icyuma cyatangiye mu 1926, gifite ubunini ntarengwa bwa NPS6 (muri santimetero, NPS1 = DN25.4). Muri iki gihe, ibyuma by'ibikoresho nka Wang Yingqiang, Dahua, Lao Demao na Maoxu na bo bafunguye gukora indangagaciro. Nyuma, kubera ubwiyongere bwo gusaba indabyo ku isoko, ikindi cyiciro cy'ibyuma, inganda z'umucanga (inganda za Catsing (inganda zafashwe) hamwe n'inganda z'imashini zafunguwe mu gukora umurongo umwe umwe.

Itsinda rya Valve ryakozwe mu turere twa Zhonghongqiao, waihongqiao, waihongqiao, kwangiza umuhanda n'umuhanda wa Charkai mu karere ka Hongkou, Shanghai. Muri icyo gihe, ibirango byagurishijwe mu gihugu byari "umutwe w'ifarashi", "bitatu 8", "inanga ebyiri", "umupira w'inkoko" n "umupira wa kagoma". Umuvuduko-muto wateye umuringa kandi wa Scope Valve Ibicuruzwa bikoreshwa cyane muguterana hejuru yinyubako no ku nyungu zikoreshwa nazo zikoreshwa mu nzego z'inganda. Ibi bikoresho ni bito cyane mubipimo, hamwe nikoranabuhanga ryinyuma, ibikoresho byoroheje byo gutera no gusohoka bya valve, ariko niyo mvugo yambere yubushinwa. Nyuma, nyuma yo gushinga ibyuma bya Shanghai yubatswe shanghai, aba bande ba valve binjiye mu ishyirahamwe rimwe nyuma yizindi bagahinduka itsinda ryamazi. umunyamuryango.

02To nini-nini ya valve ingana

Mu ntangiriro za 1930, Shanghai Shenhe Groug Great Mackin yakorewe umuvuduko ukabije witwa SHAKA Irembo rya NPS12 kumazi. Mu 1935, uruganda rwashyizeho uruganda ruhuriweho n'ibyuma bya Xiangfeng na Xiangtai CO.≈3.33m) Lathes n'ibikoresho byo guterura ibikoresho, cyane cyane bikora ibikoresho by'inganda no gucukura amabuye y'agaciro, bikaba byatangaga impamyabumenyi yuzuye ku bimera by'amazi, kandi bikaba byarateganijwe kandi bikaba byatangaga kandi bikaba byatangajwe na Nanjing, Hangzhou na Beijing. Nyuma ya "13 Kanama" Abateye Abayapani bigaruriye Shanghai mu 1937, ibyinshi mu bimera n'ibikoresho biri mu ruganda byasenyutse n'umuriro w'abayapani. Umwaka ukurikira wongerewe umurwa mukuru kandi wongeye imirimo. NPS14 ~ NPS36 Fata Irembo ryicyuma, ariko kubera ubucuruzi bwihungabana mu bukungu, ubucuruzi bunebwe, n'ubugome bwateye ubwoba, ntibyashoboye gukira kugeza ku ibanzi w'Abashinwa bashinzwe.

Mu 1935, abanyamigabane batanu barimo Li Chenghai, umucuruzi w'igihugu, yashinze umutwe Shenyang Chengfa (uwabanjirije Uruganda ruhambiriye) ku muhanda wa Shishiwei, Akarere ka Nancheng, Umujyi wa Nancheng, Shenyang. Gusana no gukora indangagaciro. Mu 1939, uruganda rwimuriwe mu muhanda wa Beiesma, akarere ka TIEXI kaguka, kandi amahugurwa abiri manini yo guta no gucuruza yubatswe. Kugeza mu 1945, yari yarakuze ku bakozi 400, n'ibicuruzwa byayo nyamukuru byari: Abakandara-nini, bajugunye indangagaciro z'umuringa, kandi mu nsi zo munsi irembo ry'icyuma munsi ya DN800. Shenyang Chengfa Uruganda rwicyuma ni uruganda rukora valve rurwana no kubaho mu Bushinwa bwa kera.

03Inganda za valve inyuma

Mu ntambara yo kurwanya abayapani, imishinga myinshi i Shanghai n'ahandi kwimukira mu majyepfo y'uburengerazuba, bityo umubare w'imigeri muri Chongqing n'ahandi mu gace k'inyuma byarazamutse. Mu 1943, uruganda rwa Chongqing Uruganda rwa Hongtai n'imashini z'imashini za Huachang (rubanjirije abanjirije uruganda rwa Chongqing) rwatangiye gukora ibintu byinshi ndetse n'umuvuduko w'igituba. Nyuma yo gutsinda intambara yo kurwanya ikiyapani, uruganda rwibyuma rwa Lisheng, umuryango winganda wa Zhenxing, uruganda rwibikoresho bya jiyi na jiyi. Nyuma yo gushingwa mu Bushinwa bushya, ibyo bikoresho byahujwe mu ruganda rwa Chongqing valve.

Icyo gihe, bamweAbakora ValveI Shanghai na we yagiye i Tianjin, Nanjing na Wuxing kubaka inganda zo gusana no gukora indangagaciro. Inganda zimwe na zimwe z'ibyuma, inganda z'icyuma, imashini zinganda cyangwa abapadiri muri Beijing, Harbin, Fuzhao, Fuzshao na Guangzhou na bo bagize uruhare mu gusana no gukora indangagaciro.
