Mfundo yogwirira ntchito ndi gulu la ma check valve
Chongani valavu: valavu yoyang'ana imadziwikanso kuti cheke valavu kapena valavu, ntchito yake ndikuletsa payipi yapakati kubwerera.Kukoka kwa pampu yamadzi kuchokera pansi pa valve kumakhalanso kwa valve yowunika.Magawo otsegulira ndi otseka amatsegulidwa kapena kutsekedwa ndi kuyenda ndi mphamvu yapakati kuti ateteze kubwereranso kwa valve yapakati yotchedwa check valve.Vavu yowunikira ndi ya gulu la ma valve okha, valavu yowunikira imagwiritsidwa ntchito makamaka panjira imodzi ya media papaipi, imangolola media kuti iziyenda mbali imodzi, kuteteza ngozi.Chongani valavu molingana ndi kapangidwe, akhoza kugawidwa mu kukweza cheke valavu, swing cheke valavu ndi valavu gulugufe cheke atatu.Nyamulani valavu yoyang'ana imatha kugawidwa kukhala valavu yoyang'ana yoyima ndi valavu yoyang'ana yopingasa iwiri.Valavu yoyang'ana ya swing imagawidwa kukhala valavu imodzi yoyang'ana ma disc, valavu yoyang'ana ma disc awiri ndi valavu yoyang'ana ma disc ambiri.Gulugufe loyang'ana valavu ya valavu yowongoka, mavavu angapo omwe ali pamwambawa atha kugawidwa mu valavu yolumikizira ulusi, valavu yolumikizira ma flange ndi valavu yowotcherera atatu.

Kuyika ma valve kuyenera kulabadira izi:
Osakweza ma cheke ma valve pamzere.Ma valve akuluakulu a chekeni ayenera kuthandizidwa paokha kuti awateteze ku kukakamizidwa kopangidwa ndi mzere.
Mukayika, samalani ndi momwe mayendetsedwe a media akuyenera kukhalira mogwirizana ndi momwe muvi wamagetsi amayendera.
Nyamulani ma valavu oyang'ana chotchinga choyimilira amayenera kuyikidwa pamapaipi oyima.
Mavavu okweza ma disc okwera ayenera kuyikidwa pamapaipi opingasa.
Zigawo zazikulu zogwirira ntchito za valve cheke:

Zigawo zazikulu zogwirira ntchito za valve cheke:
Kupanikizika mwadzina kapena kupanikizika: PN1.0-16.0mpa, ANSI Class150-900, JIS 10-20K, m'mimba mwake mwadzina kapena m'mimba mwake: DN15 ~ 900, NPS 1/4~36, njira yolumikizira: flange, kuwotcherera matako, ulusi, socket kuwotcherera, etc., kutentha koyenera: -196 ℃~540 ℃, zakuthupi: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8(304), CF3(304L), CF8M(316), CF3M(316L), Ti.Sankhani zipangizo zosiyanasiyana, valavu cheke akhoza ankalemekeza oyenera madzi, nthunzi, mafuta, asidi nitric, asidi asidi, oxidizing sing'anga, urea ndi TV zina.
Nortech ndi m'modzi mwa otsogola opanga ma valve ku China omwe ali ndi chiphaso cha ISO9001.
Zogulitsa zazikulu:Valve ya Butterfly,Valve ya Mpira,Chipata cha Chipata,Onani Vavu,Globe Vavlve,Y-Strainers,Electric Acurator,Pneumatic Acurators .
