Valavu yoponyera imaponyedwa mu valavu, kalasi ya kuthamanga kwa valavu yoponyera ndi yotsika (monga PN16, PN25, PN40, koma palinso kuthamanga kwakukulu, kumatha kukhala 1500Lb, 2500Lb), caliber yambiri ndi yoposa DN50. Valavu yopangira imapangidwa, nthawi zambiri imagwiritsidwa ntchito mu mapaipi apamwamba, caliber ndi yaying'ono, nthawi zambiri imakhala pansi pa DN50.

Choyamba, kuponyavalavu
1, kuponya: ndi kusungunula chitsulocho kukhala madzi omwe amakwaniritsa zofunikira zina ndikuchiponya mu nkhungu, pambuyo poziziritsa ndi kulimbitsa, kuyeretsa kuti chipeze mawonekedwe, kukula ndi magwiridwe antchito a njira yoponyera (zigawo kapena zopanda kanthu). Ukadaulo woyambira wa makampani opanga makina amakono.

2, kupanga zinthu zotsika mtengo, chifukwa cha mawonekedwe ovuta, makamaka ndi ziwalo zovuta, zambiri zimatha kuwonetsa chuma chake; Nthawi yomweyo, imakhala yosinthasintha kwambiri komanso imakhala ndi mawonekedwe abwino a makina.

3, koma kupanga zinthu zoponyera zinthu kunafuna zinthu (monga chitsulo, matabwa, mafuta, zipangizo zoumbira zinthu, ndi zina zotero) ndi zipangizo (monga ng'anjo yachitsulo, makina osakanizira mchenga, makina oumbira zinthu, makina opangira zinthu pakati, makina ogwetsa mchenga, makina ophulitsira zinthu, mbale yachitsulo, ndi zina zotero) zambiri, ndipo zidzapanga fumbi, mpweya woipa, phokoso ndi kuipitsa chilengedwe.

4, kuponya ndi njira yoyambirira yopangira chitsulo chotentha, chitukuko cha liwiro la kuponya ndi chachangu kwambiri, chapanga chitsulo chosungunuka, chitsulo chosapanga dzimbiri cha kaboni chotsika kwambiri komanso mkuwa wa aluminiyamu, silicon ya aluminiyamu, aloyi ya magnesium ya aluminiyamu, titaniyamu, aloyi ya nickel ndi zinthu zina zachitsulo zoponyera, komanso njira yatsopano yopangira chitsulo chosungunuka cha imvi. Pambuyo pa zaka 50, padawonekera chitsanzo cha mchenga wonyowa, kupanga chitsanzo cha mchenga wolimba ndi pakati, kupanga chitsanzo cha kupanikizika koipa ndi kuponyera kwina kwapadera, kuyeretsa ndi kuwombera ndi ukadaulo wina watsopano.

5, pali mitundu yambiri ya kuponyera, malinga ndi njira yopangira chitsanzo yomwe mwachizolowezi imagawidwa m'magulu awa: (1) kuponyera mchenga wamba, kuphatikizapo mchenga wonyowa, mchenga wouma ndi mtundu wa mchenga wouma wa mankhwala. 3. ② Kuponyera kwapadera, zipangizo zomangira makina osindikizira ndi mchenga wamchere wachilengedwe zimatha kugawidwa m'magulu awiri: mchenga wamchere wachilengedwe monga zinthu zazikulu zopangira kuponyera (monga kuponyera ndalama, kuponyera nkhungu, kuponyera nkhungu, kuponyera nkhungu ya chipolopolo, kuponyera koipa, kuponyera nkhungu, kuponyera nkhungu ya ceramic, etc.) ndi chitsulo ngati zinthu zazikulu zopangira nkhungu zapadera (monga kuponyera nkhungu yachitsulo, kuponyera kopanikizika, kuponyera kosalekeza, kuponyera kotsika, kuponyera kwa centrifugal, etc.).

6, njira yopangira zinthu nthawi zambiri imaphatikizapo: (1) kuponyedwa (zotengera) kumapanga chitsulo chamadzimadzi chopangidwa ndi kuponyedwa kolimba, kuponyedwa molingana ndi zipangizo kungagawidwe m'magulu a mchenga, chitsulo, ceramic, matope, graphite, ndi zina zotero, kungagawidwe pogwiritsa ntchito mtundu wotayidwa, theka lokhazikika komanso lokhazikika, khalidwe la kukonzekera nkhungu ndi zinthu zazikulu zomwe zimakhudza khalidwe la kuponyedwa; (2) kusungunuka ndi kuponyedwa kwa chitsulo chopangidwa ndi kuponyedwa, chitsulo chopangidwa ndi kuponyedwa (chopangidwa ndi aloyi) makamaka ndi chitsulo chopangidwa ndi kuponyedwa, chitsulo chopangidwa ndi aloyi wosakhala ndi chitsulo; Kukonza ndi kuyang'anira kuponyedwa, kuponyedwa kwa mankhwala kuphatikizapo kuchotsa pakati ndi pamwamba pa matupi akunja, kuchotsa chopopera chothira, kupukuta kwa fosholo ndi msoko ndi zina zotuluka ndi kutentha, pulasitiki, chithandizo cha dzimbiri ndi kukonza molakwika. Valavu ya pampu yolowera

Nortech ndi m'modzi mwa opanga ma valve otsogola ku China omwe ali ndi satifiketi ya ISO9001 yapamwamba.

Zinthu zazikulu:Valavu ya Gulugufe,Valavu ya Mpira,Valavu ya Chipata,Valavu Yowunikira,Globe Vavlve,Zipangizo za Y,Chotsukira Magetsi,Zipangizo zoyezera mpweya (Pneumatic Acurators).
