Chithunzi cha GLV504-PN16
Amapangidwa makamaka kuti azitha kuwononga mankhwala owononga komanso otentha kwambiri, mavavu otsekedwa ndi ma bellow amapangidwa ndi zitsulo zambiri zopindika, zosinthika kuti zisawonongeke ndi mankhwalawa. Mavuvu amawotcherera ku tsinde la valavu ndi boneti, pamodzi ndi kusindikiza koyenera kwa ziwalo, kuthetsa kutayikira komwe kungatheke.Kupangidwa mogwirizana ndi miyezo yapadziko lonse lapansi, mavavu athu otsekedwa ndi mavuvu amadzitamandira ntchito yabwino yosindikiza komanso moyo wautali wozungulira. Akatswiri oyenerera amayesa nthawi zonse ma valve athu apadziko lonse lapansi kuti achepetse kutayikira, motero amachepetsa zofunika kukonza.

Kumanga Thupi
Chifukwa cha ma angles mu thupi la valve ya globe pali kutayika kwakukulu kwa mutu. Kutaya mutu ndi muyeso wa kuchepetsa mutu wonse wamadzimadzi pamene ukuyenda mu dongosolo. Kutayika kwathunthu kwa mutu kumatha kuwerengedwa pofotokoza mwachidule mutu wokwezeka, mutu wa liwiro ndi mutu wopanikizika. Ngakhale kutayika kwa mutu sikungalephereke m'makina amadzimadzi, kumawonjezeka ndi zopinga ndi discontinuities mumayendedwe othamanga monga mawonekedwe a S a globe valve design. Thupi ndi mapaipi othamanga ndi ozungulira komanso osalala kuti apereke kayendedwe ka kayendedwe popanda kuchititsa chipwirikiti kapena phokoso. Kuti mupewe kupangitsa kuti pakhale zotayika zochulukirapo pa liwiro lalikulu mapaipi ayenera kukhala malo osasintha. Mavavu a Globe amapezeka m'magulu atatu akuluakulu a thupi (ngakhale kuti mapangidwe ake aliponso): kapangidwe ka ngodya, mawonekedwe a Y, ndi mawonekedwe a Z.
