Ma valve a Globe ndi ma valve otsekera oyenda omwe amagwiritsidwa ntchito poyambira, kuyimitsa kapena kuwongolera kuyenda pogwiritsa ntchito membala wotseka wotchedwa disc.Mpando wa valavu ya globe uli pakati ndi yofanana ndi chitoliro, ndipo kutsegula pampando kumatsekedwa ndi diski kapena plug.The globe valve disc ikhoza kutseka kwathunthu njira yotuluka kapena ikhoza kuchotsedwa kwathunthu.Kutsegula kwa mpando kumasintha mofanana ndi kuyenda kwa chimbale chomwe ndi choyenera kwa ntchito zokhudzana ndi kayendetsedwe ka kayendetsedwe kake.Mavavu a globe ndi oyenera kwambiri ndipo amagwiritsidwa ntchito kwambiri kuwongolera kapena kuyimitsa kutuluka kwamadzi kapena gasi kudzera papaipi kuti ayendetse ndikuwongolera kutuluka kwamadzimadzi ndipo nthawi zambiri amagwiritsidwa ntchito pamapaipi ang'onoang'ono.

ASME Globe valvendi 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.

Komanso, malingana ndi kamangidwe ka mpando ndi chimbale, mipando katundu waMa valve a ASME padziko lonse lapansiikhoza kuyendetsedwa bwino ndi tsinde lopindika.Mphamvu yosindikiza yavalavu yapadziko lonse ya ASMEndi mkulu kwambiri.Atha kugwiritsidwa ntchito paopanda ntchito. Chifukwa cha mtunda waufupi wa diski pakati pa malo otseguka ndi otsekedwa,Ma valve a ASME padziko lonse lapansindi abwino ngati valavu iyenera kutsegulidwa ndi kutsekedwa kawirikawiri.Chifukwa chake, ma valve a globe amatha kugwiritsidwa ntchito zosiyanasiyana.

ndiMavavu a ASME GlobeItha kugwiritsidwa ntchito pazifukwa zopukutira komanso.Matupi ambiri okhala ndi ma valve okhala ndi amodzi amagwiritsa ntchito khola kapena zomangamanga kuti asungire mphete yapampando, kupereka chiwongolero cha pulagi ya valavu, ndikupereka njira zokhazikitsira mawonekedwe enaake oyenda valavu.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)

Valavu yapadziko lonse imakhala ndi chimbale chosuntha 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 likuyendetsedwa 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.
