Vali zo gucukura ni vali zikorwa hakoreshejwe icyuma. Muri rusange, igipimo cy'umuvuduko wa vali zo gucukura kiri hasi cyane (nka PN16, PN25, PN40, ariko hari n'izifite umuvuduko mwinshi, zishobora kugera kuri 1500Lb, 2500Lb), kandi inyinshi mu mashini zazo ziri hejuru ya DN50. Vali zo gucukura ni vali kandi muri rusange zikoreshwa mu miyoboro yo mu rwego rwo hejuru ifite caliber ntoya, muri rusange munsi ya DN50.
1. Gutera icyuma
1. Gushongesha: Ni inzira yo gushongesha icyuma mu mazi yujuje ibisabwa runaka no kugisuka mu ibumba. Nyuma yo gukonjesha, gukonja no gusukura, haboneka gushongesha (igice cyangwa ubusa) bifite imiterere, ingano n'imikorere byagenwe. Ikoranabuhanga ry'ibanze ry'inganda zigezweho zikora imashini.
2. Ubwoya bukozwe mu byuma nabwo burahendutse, kandi bushobora kugaragaza ubushobozi bwabwo buhendutse ku bice bifite imiterere igoye, cyane cyane bifite imyobo y’imbere igoye; ariko kandi, bufite ubushobozi bwo kwihutisha ibintu kandi bufite imiterere myiza y’ikoranabuhanga.
3. Ibikoresho (nk'ibyuma, ibiti, lisansi, ibikoresho byo kwerekana ibishushanyo, nibindi) n'ibikoresho (nk'amatanura y'icyuma, imashini zivanga umucanga, imashini zibumba, imashini zikora igice cy'imbere, imashini zizunguza, imashini zirasa, amasahani y'icyuma, nibindi) bikenewe mu gukora ibumba) Birushaho kuba byinshi, kandi bizatanga ivumbi, umwuka mubi n'urusaku kandi bihumanya ibidukikije.
4. Gucukura ni ubwoko bw'ikoranabuhanga ryo gutunganya ubushyuhe bw'icyuma abantu bamaze kumenya mbere, rifite amateka y'imyaka igera ku 6000.
Mu 3200 mbere ya Yesu, hagaragaye uburyo bwo gucukura ibikeri by'umuringa muri Mezopotamiya. Hagati y'ikinyejana cya 13 mbere ya Yesu n'ikinyejana cya 10 mbere ya Yesu, Ubushinwa bwinjiye mu bihe bikomeye byo gucukura ibikeri by'umuringa.
Ubukorikori bugeze ku rwego rwo hejuru cyane, nka Simuwu Fangding Ding ya kilometero 875 yo mu gihe cy'ingoma ya Shang, icyapa cya Zenghou Yizun cyo mu gihe cy'intambara, n'indorerwamo imurika yo mu ngoma ya Han y'Iburengerazuba byose bigaragaza uburyo ibintu bya kera byakozwe.
umusaruro. Gucukura byakozweho cyane n'ibumba, kandi inyinshi mu bikoresho byacukurwaga byari ibikoresho cyangwa ibikoresho byo mu buhinzi, idini, n'ubuzima.
Ibara ry'ubuhanzi rirakomeye. Mu 513 Mbere ya Yesu, Ubushinwa bwakoze ibumba rya mbere ku isi ku byuma bicukurwa (bipima ibiro bigera kuri 270), riboneka mu nyandiko.
Ahagana mu kinyejana cya 8, u Burayi bwatangiye gukora imashini zisuka ibyuma. Nyuma y'impinduramatwara y'inganda mu kinyejana cya 18, imashini zisuka ibyuma zinjiye mu gihe gishya cyo gukorera inganda nini.
Mu kinyejana cya 20, iterambere ryihuse ry’ubucukuzi ryaratewe imbere. Ibyuma bikozwe mu buryo bwa "nodular cast iron", "malleable cast iron", "ultra-low carbon stainless steel", "aluminium copper", "aluminium silicon", na "aluminium-magnesium alloys" byagiye bitera imbere uko bikurikirana.
Gucukura ibikoresho by'icyuma nka titanium-based na nickel-based alloys, kandi bavumbuye uburyo bushya bwo gutera icyuma cy'umukara. Nyuma y'imyaka ya 1950, hagaragaye icyitegererezo cy'umucanga utose gifite umuvuduko mwinshi,
Gukora ibishushanyo mbonera by'umucanga wo gukomera hakoreshejwe imiti no gukora igice cy'umucanga, gukora ibishushanyo mbonera by'umuvuduko mubi, ubundi buryo bwo gukata budasanzwe, guturitsa amasasu n'ubundi buryo bushya.
5. Hari ubwoko bwinshi bwo gucukura, bugabanyijemo: ①Gucukura umucanga usanzwe, harimo ubwoko butatu bw'umucanga w'icyatsi kibisi, umucanga wumye n'umucanga ukomeye cyane. ②Gucukura byihariye, hakurikijwe ibikoresho byo gucukura, bishobora kugabanywamo gucukura byihariye hamwe n'umucanga w'amabuye y'agaciro karemano n'amabuye nk'ibikoresho by'ingenzi byo gucukura (nk'ishoramari, gucukura ibumba, gucukura imashini yo mu iduka, gucukura umuvuduko mubi, gucukura bikomeye, gucukura ceramic) n'ibindi) hamwe no gucukura byihariye hamwe n'icyuma nk'ibikoresho by'ingenzi byo gucukura (nk'icukura icyuma, gucukura umuvuduko, gucukura bidatinze, gucukura umuvuduko muke, gucukura centrifugal, nibindi).
6. Uburyo bwo gucukura busanzwe burimo: ①Gutegura ibumba (ibikoresho bikora icyuma cy'amazi mu gucukura bikomeye). Ibumba rishobora kugabanywamo umucanga, icyuma, ceramic, ibumba, grafiti, nibindi, hakurikijwe inshuro zikoreshwa. Ku bijyanye n'ikoreshwa rishobora gukoreshwa, rihoraho kandi rihoraho, ubwiza bw'ibumba ni cyo kintu cy'ingenzi bigira ingaruka ku bwiza bw'ibumba; ②Gushonga no gusuka ibyuma, ibyuma bicukurwa (ibumba rikozwe mu buryo bwa alloys) birimo icyuma gikozwe mu buryo bwa alloys, icyuma gikozwe mu buryo bwa alloys n'ibumba rikozwe mu buryo bwa alloys zitarimo feri; ③ Gutunganya no kugenzura ibumba. Gutunganya ibumba birimo gukuraho ibyavuye mu mahanga ku gice cyo hagati no hejuru cy'ibumba, gukuraho imashini zisuka, gukata ibumba n'imigozi, hamwe no gutunganya ubushyuhe, gushushanya, kurwanya ingese no gukora imashini ikaze. Valve y'ipompo yo mu gihugu

Nortech ni imwe mu nganda zikomeye mu gukora valve mu Bushinwa ifite icyemezo cy’ubuziranenge cya ISO9001.
