BS1873 valavu yapadziko lonse lapansi

ndi imodzi mwa mapangidwe otchuka a mavavu padziko lonse lapansi, kwa US ndi API system.m'mimba mwake, zipangizo, nkhope ndi maso, khoma makulidwe, kutentha kwapakati, zimatanthauzidwa ndi ASME B16.34.

ndiBS1873 valavu yapadziko lonse lapansiItha kugwiritsidwa ntchito pazifukwa zopukutira komanso.Matupi ambiri okhala ndi ma valve okhala ndi amodzi amagwiritsa ntchito khola kapena zomangamanga kuti asunge mphete yapampando, kupereka chiwongolero cha pulagi ya valavu, ndikupereka njira zokhazikitsira mawonekedwe enaake oyendera ma valve.Itha kusinthidwanso mosavuta ndi kusintha kwa magawo ang'onoang'ono kuti asinthe mawonekedwe otaya kapena kupereka mphamvu yocheperakokuthamanga, kutsitsa phokoso, kapena kuchepetsa kapena kuchotsa cavitation.

ASME Globe Valve Body Patterns, pali mitundu itatu yayikulu ya thupi kapena mapangidwe a mavavu a Globe, omwe ndi:

1).Standard Pattern (yomwe imadziwikanso kuti Tee Pattern kapena T - Pattern kapena Z - Pattern)
2)
3).Oblique Pattern (yomwe imadziwikanso kuti Wye Pattern kapena Y - Pattern)

Mfundo Yogwira Ntchito yaBS1873 valavu yapadziko lonse lapansi

Vavu yapadziko lonse imakhala ndi chimbale chosunthika komanso mpando wa mphete woyima mu thupi lozungulira.Mpando wa valavu yapadziko lonse uli pakati ndikufanana ndi chitoliro, ndipo kutsegula kwa mpando kumatsekedwa ndi diski.pamene gudumu lamanja likuzungulira pamanja kapena ndi actuator, kayendetsedwe ka disc kamayang'aniridwa (kutsika kapena kukwezedwa) pogwiritsa ntchito tsinde la valve.Pamene globe valve disc ikukhala pamwamba pa mphete ya mpando, kutuluka kumayimitsidwa kwathunthu.

Mbali yaikulu ya BS1873 valavu yapadziko lonse lapansi

1)Kukwanitsa kusindikiza bwino
2)) Mtunda waufupi woyenda wa disc (stroke) pakati pa malo otseguka ndi otsekedwa,Ma valve a ASME padziko lonse lapansindi abwino ngati valavu iyenera kutsegulidwa ndi kutsekedwa kawirikawiri;
3).Valavu ya ASME yapadziko lonse lapansi itha kugwiritsidwa ntchito ngati valavu yowunika posintha kapangidwe kake.
4).Tapa pali kuthekera kosiyanasiyana komwe kulipo mu tee, Wye, ndi masitaelo a thupi.

1). Zapangidwira mapaipi pafupipafupi omwe amazimitsa, kapena kutsitsa madzi ndi mpweya
2) .Fluids: Madzi, nthunzi, mpweya, mafuta a petroleum ndi mafuta, gasi, gasi condensate, njira zamakono, mpweya, madzi ndi mpweya wosaopsa.
3).Mafuta ndi Gasi, Madzi a Feedwater, chakudya chamankhwala, Makina oyeretsera, kutulutsa mpweya wa condenser, ndi makina otulutsa.
4).Maboiler ndi ngalande, ntchito za nthunzi, polowera nthunzi zikuluzikulu ndi ngalande, ndi ngalande za heater.
