Makhalidwe Ofunika

Kodi malire ogwirira ntchito ndi otani?

Vavu ya carbon steel globe iyi imakhala ndi ntchito yokhazikika yotetezeka mkati mwa kutentha kwapakati pa -29 ℃ mpaka 425 ℃. Ikagwira ntchito pansi pa gulu lake lofananira, imasunga chisindikizo chokhazikika popanda kutayikira, ndipo mawonekedwe ophatikizika a valve amakhalabe osasunthika komanso osasinthika. Imagwira ntchito mosasunthika panthawi yogwira ntchito m'mafakitale usana ndi usiku, kuthana ndi kutsegulira ndi kutseka pafupipafupi komanso kusinthasintha kwa kutentha kwa ntchito.

Amagwiritsidwa ntchito chiyani?

Valavu iyi idapangidwa kuti izigwira ntchito ziwiri zazikuluzikulu zapamalo: kuwongolera bwino kuyenda komanso kudzipatula kwathunthu kwa mapaipi. Zimagwira ntchito bwino ndi madzi, mafuta amafuta, gasi wachilengedwe, nthunzi komanso madzi ambiri omwe amapangidwa m'mafakitale. Mutha kuzipeza kuti zimayikidwa pamapaipi amagetsi a mafakitale amafuta, mizere yopangira mafuta a petrochemical, malo opangira magetsi otentha, malo oyeretsera madzi oyipa komanso malo opangira zinthu wamba, ndikuwongolera kuperekera kwapakatikati mumitundu yonse yamafakitale apakati komanso kutentha kwambiri.

Chifukwa chiyani kusankha chitsulo cha carbon?

Timagwiritsa ntchito A216 WCB zitsulo za carbon poponyera thupi la valve. Nkhaniyi imakhala ndi kuuma kwamphamvu, kukana kukakamiza bwino ndipo imatha kupirira kutentha kwambiri. Sichidzawonongeka mosavuta pansi pa zovuta zogwirira ntchito, mtengo wake ndi wotsika mtengo komanso moyo wautumiki ndi wautali, choncho ndiye chisankho chodziwika bwino cha ma valve okhazikika padziko lonse lapansi.

Ndi media iti yomwe ingagwire? Ndi media iliyonse yoti mupewe?

Oyenera madzi oyera, nthunzi, mafuta otentha, wothinikizidwa mpweya, mafuta kuwala. Osati amphamvu asidi/alkali mkulu-zimbiri madzimadzi; pewani sing'anga yokhala ndi tinthu tating'ono tambiri tomwe timakanda pamwamba.

Chifukwa chiyani musankhe valavu ya globe m'malo mwa valavu yachipata cha chingwe cha nthunzi?

Valavu ya Globe imathandizira kutseguka kosinthika pakuwongolera kolondola & kuwongolera kuthamanga. Vavu yachipata imagwira ntchito yotseguka / yotseka kwathunthu popanda kuwongolera ntchito. Valavu ya Globe imakhala yomata kwambiri pansi pa nthunzi yotentha kwambiri ndipo imapewa nyundo yamadzi yapaipi.         

Zofunikira pakuyika flange?

Chotsani chosindikizira cha flange kuti muchotse slag ndi dzimbiri; gwiritsani ntchito ma graphite a GB / PTFE gasket; kumangitsa mabawuti symmetrically wogawana kuteteza flange kutayikira; osapitirira-torque kuti muphwanye gasket.

Kodi valavu yapadziko lonse lapansi ili ndi malire oyika?

Inde. Ikani motsatira muvi wothamanga pa thupi la valve (media kutuluka kuchokera pansi pa diski kupita pamwamba pa diski). Kuyikira kumbuyo kumayambitsa kusasindikiza bwino, kugwira ntchito molimba komanso kubwerera m'mbuyo. Tsinde liyenera kukhala loyima pakuyika.
