    Valavu ya Gulugufe Yozungulira Katatu

    Thevalavu ya gulugufe yozungulira katatu— yomwe imadziwikanso kuti valavu ya gulugufe ya triple offset — ndi valavu ya gulugufe yokhala ndi zitsulo yolimba kwambiri yopangidwira ntchito zoyendera pa kuthamanga kwambiri, kutentha kwambiri, komanso pafupipafupi pomwe mavalavu okhala ndi mipando yofewa sangagwiritsidwe ntchito. Mavavu atatuwa amachotsa kukangana kulikonse pakati pa diski ndi mpando potsegula ndi kutseka, zomwe zimapangitsa kuti mpando usakhale wovala bwino pa nthawi iliyonse. Mpandowo ndi wofunikira kwambiri pa thupi la valavu, wokutidwa ndi zinthu zotsutsana ndi kusweka komanso ma angles okhala bwino, pomwe mphete zofewa kapena zotsekera zachitsulo zokhala ndi zigawo zambiri zimakhazikika pa diski — zomwe zimapereka kukana kwakukulu ku kutentha, kupanikizika, ndi dzimbiri. Yopangidwa molingana ndi API 609, ANSI B16.10 yoyang'anizana ndi nkhope, kutentha kwa kupanikizika pa ASME B16.34. Kuchuluka kwa kupanikizika ANSI Class 150/300/600/900. Kukula kwake ndi DN50–DN1500 (2″–60″). Zipangizo za thupi zimaphatikizapo chitsulo cha kaboni, chitsulo chosapanga dzimbiri, Monel, ndi Hastelloy. Zosankha za mipando: chisindikizo chofewa chokhala ndi zigawo zambiri kapena chitsulo chokhala ndi zitsulo. Nortech ndi kampani yotsogola yopanga ma valavu a gulugufe atatu komanso yogulitsa zinthu ku China.

  • Valavu ya Gulugufe Yogwira Ntchito Kwambiri Yokhala ndi Mphamvu Yaikulu

    Valavu ya Gulugufe Yogwira Ntchito Kwambiri Yokhala ndi Mphamvu Yaikulu

    Thevalavu ya gulugufe iwiri yosiyana— yomwe imadziwikanso kuti valavu ya gulugufe ya double offset — ili ndi ma offsets awiri osiyana omwe amachotsa diski kuchoka pampando nthawi yomweyo ikatsegulidwa, zomwe zimapangitsa kuti mpando usakhudze nthawi zonse pamene ukugwira ntchito. Kapangidwe kameneka kamachepetsa kukangana ndi kuwonongeka, kamachepetsa mphamvu yogwirira ntchito, komanso kamaonetsetsa kuti itseka bwino ngakhale kutentha kapena kupanikizika kwasintha mwadzidzidzi. Yoyenera malo ogwirira ntchito omwe ali ndi mphamvu zambiri, kutentha kwambiri, komanso ovuta kugwiritsa ntchito.Kapangidwe kosapsa ndi moto,Satifiketi ya ATEX,Yoyesedwa ku ANSI Class 150/300/600 ndi PN16–PN100, kukula kwake ndi DN50–DN1800 (2″–72″). Yopangidwa kutengera API 609, yoyang'anizana ndi ANSI B16.10, kutentha kwa kuthamanga pa ASME B16.34. Thupi lake ndi chitsulo cha kaboni kapena chitsulo chosapanga dzimbiri, disc mu chitsulo chosapanga dzimbiri, mpando wake ndi PTFE kapena RPTFE. Yotsimikizika ku mayeso a moyo wa 1,000,000-cycle ndi magwiridwe antchito a zero-leakage bi-directional. Kuchuluka kwa ma valve body castings — kutumizidwa mkati mwa masabata 3-5 pa maoda ambiri. Nortech ndi kampani yopanga ma valve a butterfly komanso yogulitsa ma valve amitundu iwiri ku China.
