Hard Seal Globe Valve

Zimabwera ndi zolumikizira za flanged ndipo zimakhala ndi zomangira zosindikizira zachitsulo mpaka zitsulo. Imadula kutulutsa kwamadzimadzi ndi zero kutayikira ndikukulolani kuti musinthe molondola kuchuluka kwamayendedwe mkati mwa mapaipi. Matembenuzidwe a WCB amagwira ntchito bwino pazanja ndi zoulutsira mawu zamakampani, pomwe mitundu yazitsulo zosapanga dzimbiri imalimbana ndi madzi owononga. Vavu iyi imagwirizana bwino ndi petrochemical, malo opangira magetsi, zitsulo ndi ntchito zopangira madzi m'mafakitale.

Ndife akatswiri opanga ma valve okhala ndi ziphaso zathunthu za ISO, CE ndi API. Timayendetsa zida zonse zotsogola za CNC ndikuwunika mosamalitsa njira zonse zowunikira kuti zitsimikizire kuti zinthu zikuyenda bwino pamagiredi onse. Custom OEM ndi ntchito za ODM zilipo ndi MOQ yosinthika kuti ikwaniritse zofuna zosiyanasiyana. Mavavu athu olimba olimba padziko lonse lapansi amatumiza kumsika padziko lonse lapansi ndikupeza mayankho abwino kuchokera kwa anzathu apadziko lonse lapansi.

Makhalidwe Ofunika

Kodi pali kusiyana kotani pakati pa valavu yolimba ya globe yosindikizira ndi valve yofewa yapadziko lonse lapansi?

Mosiyana ndi mavavu ofewa osindikizira padziko lonse lapansi omwe amadalira PTFE, mphira kapena zida zosindikizira za pulasitiki, mavavu athu olimba osindikizira amatengera kusindikiza kolimba kwazitsulo ndi zitsulo, zokhala ndi stellite alloy hardfaced pa valve disc ndi mpando. Zisindikizo zofewa zimakhala ndi kutentha kwa chipinda, kutsika kwapansi ndi zofalitsa zoyera. Poyerekeza, mawonekedwe achitsulo chosindikizira cholimba amadzitamandira kwambiri kukana kutentha, kulekerera kwapakatikati, kukana kuvala komanso kukana kukokoloka. Sichidzawotcha, kupunduka kapena kutayikira m'malo ovuta kwambiri monga nthunzi yotentha kwambiri, mpweya wochuluka wa mafakitale ndi ma media abrasive okhala ndi tinthu tating'onoting'ono, kusungitsa kutsekedwa kolimba kwa nthawi yayitali kwa mafakitale olemetsa.

Ndi zinthu ziti za thupi zomwe ndingasankhe pa mankhwalawa, ndipo ndi ziti zomwe zikugwirizana ndi mapaipi anga?

Timapereka zida ziwiri zomwe zimagwiritsidwa ntchito kwambiri ndi mavavu kuti zigwirizane ndi zochitika zosiyanasiyana zamafakitale: WCB carbon steel, komanso 304 ndi 316L chitsulo chosapanga dzimbiri.

WCB carbon steel ili ndi mawonekedwe olimba komanso kuthamanga kwakukulu konyamula mphamvu pamtengo wopikisana. Zimagwira ntchito bwino ndi zofalitsa zosawononga zinthu monga nthunzi ya mafakitale, madzi ozungulira, mpweya woponderezedwa ndi mafuta okhazikika a mafakitale, ndipo amagwiritsidwa ntchito kwambiri m'malo opangira magetsi, mapaipi otenthetsera ndi makina opangira mapaipi a fakitale.

Ngati payipi yanu ili ndi acidic, alkaline kapena oxidizing madzi, sankhani 304 kapena 316L chitsulo chosapanga dzimbiri. Maphunzirowa amalimbana ndi dzimbiri ndi kukokoloka kwa mankhwala bwino kwambiri, zomwe zimawapangitsa kukhala oyenerera zomera zamankhwala, mizere yamankhwala, kuthira madzi onyansa komanso malo ogwirira ntchito akunyanja.

Ziribe kanthu kuti mungasankhe chiyani, ziwalo zonse zosindikizira zamkati zimabwera ndi zokutira zolimba za stellate. Mavavu onse amalandila chithandizo chofananira cha stellite, kotero gawo lililonse limapereka kukana kolimba komanso kusindikiza kosasintha.

Kodi mavavu azitsulo zolimba zosindikizira amasindikiza popanda kutayikira kulikonse?

Mavavu ambiri achitsulo olimba osindikizira amalimbana ndi kutayikira kwapang'onopang'ono chifukwa cha makina ovuta komanso kusalondola bwino. Komabe, zogulitsa zathu zimagwiritsa ntchito ukadaulo wokometsedwa wa stellite hardfacing ndi njira yolondola kwambiri yolumikizirana, ikukwaniritsa miyezo yotseka ya API. Mosiyana ndi kusindikiza zotanuka kwa mavavu osindikizira ofewa, kusindikiza kwathu kwachitsulo kumadalira kuyika kwakuthupi kolondola kwambiri. Timasindikiza chigawo chilichonse ndi zida zenizeni za CNC ndikugaya malo osindikizira kangapo pamanja. Izi zimalola ma disc a valve ndi mpando kuti zigwirizane mwamphamvu popanda mipata. Valavu imakhala ndi kutayikira kwa zero pansi pa kutentha kwa ntchito ndi kukakamizidwa, ndipo chisindikizocho chimakhala chodalirika ngakhale pambuyo pa ntchito zambiri zotseguka.

Kodi ntchito zogwirira ntchito ndi zoletsa zotani za ma valve olimba a globe?

Mndandanda wa ma valve osindikizira olimba awa amapangidwira mwapadera kutentha kwambiri, kuthamanga kwambiri, kusokoneza komanso kugwirira ntchito kwa mafakitale. Imasinthasintha pama media osiyanasiyana ovuta monga nthunzi yotentha kwambiri, mafuta osapsa, gasi wachilengedwe, njira zowononga mankhwala, tinthu tating'onoting'ono tating'ono komanso gasi wosakanikirana wamakampani. Amagwiritsidwa ntchito kwambiri mu petrochemical, magetsi opangira magetsi, zitsulo, migodi, mankhwala opangira madzi m'mafakitale ndi ntchito zatsopano zamagetsi.

Chifukwa chiyani ma valve osindikizira olimba amakhala ndi moyo wautali wautumiki kuposa ma valve wamba amakampani?

Moyo wautali wautumiki umatsimikiziridwa ndi ubwino wapawiri wa zipangizo zamakono ndi kupanga. Choyamba, thupi la vavu limatenga njira yoponyera yophatikizika yokhala ndi mawonekedwe amkati, opanda mabowo amchenga kapena porosity, komanso mphamvu yolimbana ndi kupsinjika komanso kutsutsa-deformation. Kachiwiri, zigawo zapakati zosindikizira zimakutidwa ndi aloyi olimba kwambiri a stellite, omwe kukana kwawo kuvala komanso kukhazikika kwa kutentha kuli bwino kwambiri kuposa malo wamba osindikizira zitsulo zosapanga dzimbiri. Pakadali pano, mawonekedwe apadera oyenda a valve yapadziko lonse lapansi amapewa kukhudza kwapakatikati pamadzi osindikizira, kuchepetsa abrasion bwino.

Kodi ma valve olimba osindikizira ndi ovuta kuwayika ndikuwongolera?

Ayi ndithu. Ma valve athu onse olimba osindikizira amatengera kulumikizidwa kwa flange, kutsata miyezo yapadziko lonse lapansi ya API, CE ndi ISO, yomwe imagwirizana ndi mapaipi ambiri apadziko lonse lapansi ndipo imathandizira kusinthira mwachindunji pamalowo ndikuyika mwachangu. Mapangidwe ophatikizika a modular ndi osavuta komanso omveka, okhala ndi tsinde la valve, disc ndi mpando kuti musinthe pang'ono. Kukonza tsiku ndi tsiku ndikosavuta kwambiri: kungochotsa zonyansa zamapaipi ndi kuthirira koyenera kwa tsinde ndikofunikira, kupulumutsa nthawi komanso mtengo wamalonda pambuyo pake.
