Imyanda yo guteramo ni valve ikozwe na casting.Mubisanzwe, igipimo cyumuvuduko wibikoresho bya castes biri hasi cyane (nka PN16, PN25, PN40, ariko hariho n’umuvuduko ukabije, ushobora kugera kuri 1500Lb, 2500Lb), kandi kaliberi zabo zose ziri hejuru ya DN50.Indangantego zimpimbano zarahimbwe kandi zisanzwe zikoreshwa mumiyoboro yo murwego rwohejuru hamwe na kalibiri ntoya, muri rusange munsi ya DN50.
1. Gukina
1. Gutera: Nuburyo bwo gushonga ibyuma mumazi yujuje ibisabwa hanyuma ukabisuka mubibumbano.Nyuma yo gukonjesha, gukomera, no gukora isuku, casting (igice cyangwa ubusa) ifite imiterere yabigenewe, ingano n'imikorere iraboneka.Ubuhanga bwibanze bwinganda zikora imashini zigezweho.
2. Ubwoya bwakorewe mu bwoya nabwo buri hasi kubiciro, kandi burashobora kwerekana imikorere yubukungu kubice bifite imiterere igoye, cyane cyane hamwe nu mwobo w'imbere;icyarimwe, ifite imiterere nini yo guhuza n'imiterere myiza yubukanishi.
3. Ibikoresho (nk'icyuma, ibiti, lisansi, ibikoresho byo kwerekana, n'ibindi) n'ibikoresho (nk'itanura rya metallurgjiya, ivanga umucanga, imashini zibumba, imashini zikora intoki, imashini zinyeganyeza, imashini ziturika, ibyuma bikozwe mu cyuma, n'ibindi) bisabwa mu guta umusaruro) Nibyinshi, kandi bizatanga umukungugu, gaze yangiza n urusaku kandi bihumanya ibidukikije.
4. Gutera ni ubwoko bwa tekinoroji yo gutunganya ubushyuhe bwabantu abantu bamenye mbere, hamwe namateka yimyaka 6000.
Mu 3200 mbere ya Yesu, muri Mezopotamiya hashyizweho ibikeri by'umuringa.Hagati y'ikinyejana cya 13 mbere ya Yesu mbere y'ikinyejana cya 10 mbere ya Yesu, Ubushinwa bwinjiye mu bihe byiza byo guta umuringa.
Ubukorikori bugeze ku rwego rwo hejuru cyane, nka kg 875 ya Simuwu Fangding Ding yo mu ngoma ya Shang, isahani ya Zenghou Yizun yo mu gihe cy’ibihugu by’Intambara, kandi indorerwamo isobanutse yo ku ngoma y’iburengerazuba ya Han ni yo ihagarariye abakinnyi ba kera.
ibicuruzwa.Gukina hakiri kare byatewe cyane nububumbyi, kandi ibyinshi mubikinisho byari ibikoresho cyangwa ibikoresho byo gukora ubuhinzi, idini, nubuzima.
Ibara ry'ubuhanzi rirakomeye.Mu 513 mbere ya Yesu, Ubushinwa bwataye ibyuma bya mbere ku isi (uburemere bwa kilo 270), ushobora kubisanga mu nyandiko.
Ahagana mu kinyejana cya 8, Uburayi bwatangiye gukora ibyuma.Nyuma ya Revolisiyo yinganda mu kinyejana cya 18, abakinnyi binjiye mu gihe gishya cyo gukorera inganda nini.
Mu kinyejana cya 20, iterambere ryihuse rya casting ryatejwe imbere.Ibyuma bya Nodular, ibyuma byoroshye, ibyuma bya karuboni ntoya cyane, ibyuma bya aluminiyumu, silikoni ya aluminium, hamwe na aluminium-magnesium alloys byakozwe neza.
Gutera ibikoresho byicyuma nka titanium na nikel ishingiye kuri nikel, kandi byavumbuye uburyo bushya bwo gutera icyuma cyumukara.Nyuma ya 1950, kwerekana umuvuduko ukabije wumucanga utose,
Imiti ikomera yumucanga no gukora intangarugero, kwerekana umuvuduko mubi, ubundi buryo budasanzwe bwo gutara, guturika kurasa hamwe nubuhanga bushya.
5. Hariho ubwoko bwinshi bwa casting, bugabanijwemo: cast Gutera umucanga bisanzwe, harimo ubwoko 3 bwumucanga wicyatsi, umucanga wumye numucanga ukomye.CastGukina bidasanzwe, ukurikije ibikoresho byerekana icyitegererezo, birashobora kugabanywamo ibice bidasanzwe hamwe numucanga wamabuye y'agaciro na kaburimbo nkibikoresho byingenzi byerekana urugero (nko gushora imari, gutera ibumba, guteramo ibishishwa byo guteramo ibishishwa, gutera igitutu kibi, guterana cyane, ceramic) Ibikurikira) hamwe no gutara bidasanzwe hamwe nicyuma nkibikoresho byingenzi byingenzi (nko guteramo ibyuma, gutera igitutu, guhora utera, gutera umuvuduko muke, guta centrifugal, nibindi).
6. Igikorwa cyo gukina gikunze kubamo: reGutegura ibishushanyo (kontineri ikora ibyuma byamazi mumashanyarazi akomeye).Ibishushanyo birashobora kugabanywamo umucanga, ibyuma, ceramic, ibumba, grafite, nibindi, ukurikije inshuro zikoreshwa.Kubijugunywa, igice gihoraho kandi gihoraho, ubwiza bwimyiteguro ni ikintu nyamukuru kigira ingaruka kumiterere ya casting;MelGushonga no gusuka ibyuma bikozwe, ibyuma bikozwe (casting alloys) ahanini birimo ibyuma bikozwe mu cyuma, ibyuma bikozwe mu byuma ndetse n’ibishishwa bidafite ferrous;Gutunganya no kugenzura.Gutunganya ibicuruzwa birimo kuvanaho imibiri y’amahanga hejuru yubuso no hejuru ya casting, kuvanaho impanuka zisuka, gutobora burrs hamwe na drape, hamwe no kuvura ubushyuhe, gushiraho, kuvura anti-rust hamwe no gutunganya imashini.Kuzana ibicuruzwa bya pompe

Nortech nimwe mubakora inganda zikora inganda zikomeye mubushinwa hamwe nicyemezo cyiza ISO9001.

Ibicuruzwa byingenzi:Ikinyugunyugu,Umupira,Irembo,Reba Valve,Globe Vavlve,Y-Imyitozo,Amashanyarazi,Indwara ya pneumatike.
