Muyezo wadziko lonse womwe umagwiritsidwa ntchito kwambirivalavu ya chipatandi valavu ya chipata cha wedge. Kapangidwe kake ndi kakuti malo awiri otsekera pa chipata cha wedge ndi malo otsekera a mizere iwiri yoyenda pa thupi la valavu amapanga awiri otsekera kuti akwaniritse zotsatira zotsekera. Kapangidwe kake ndi kosavuta, ndipo madzi ake ndi ochepa, ndipo nthawi zambiri amagwiritsidwa ntchito poyendetsa mtunda wautali, mapaipi ndi zida zamadzi, mafuta, gasi ndi zina. Cholinga chogwiritsa ntchito chipata cha wedge ndikuwonjezera katundu wothandizira wotsekera, kuti valavu ya chipata cha mode yotsekedwa ndi chitsulo itseke kuthamanga kwapakati komanso kuthamanga kwapakati kochepa. Mukatseka, tembenuzani tsinde la valavu mozungulira kuti pamwamba pa valavu ya chipata ndi pamwamba pa thupi la valavu zikhale pafupi kuti mupeze chisindikizo. Komabe, kuthamanga kwapadera kwa seal kumapeto kwa valavu ya chipata cha mode yotsekedwa ndi chitsulo komwe kumapangidwa ndi wedding action nthawi zambiri sikokwanira kuti mupeze chisindikizo cha polowera. Chifukwa chake, valavu ya chipata cha mode yotsekedwa ndi chitsulo ndi chisindikizo chokakamizidwa cha mbali imodzi.
Nthawi zogwiritsira ntchito valve ya chipata cha mode:
Kuchuluka kwa ntchito ndi mawonekedwe a valavu ya wedge ya dziko lonse, pakati pa mitundu yosiyanasiyana ya mavalavu, valavu ya chipata ndiyo yomwe imagwiritsidwa ntchito kwambiri. Nthawi zambiri imangoyenera kutsegulidwa kwathunthu kapena kutsekedwa kwathunthu, ndipo singagwiritsidwe ntchito pokonza ndi kutsekereza.
Ma valve a chipata cha mode nthawi zambiri amagwiritsidwa ntchito nthawi zina pamene palibe lamulo lokhwima pa miyeso yakunja ya valavu, ndipo mikhalidwe yogwiritsira ntchito ndi yovuta kwambiri. Monga malo ogwirira ntchito otentha kwambiri komanso kuthamanga kwambiri, ndikofunikira kuti ziwalo zotsekera zitsekedwe kwa nthawi yayitali.
Kawirikawiri, mikhalidwe kapena zofunikira pakugwiritsa ntchito zimafuna magwiridwe antchito odalirika otsekera, kuthamanga kwambiri, kudula kwa kuthamanga kwambiri (kusiyana kwakukulu kwa kuthamanga), kudula kwa kuthamanga kochepa (kusiyana pang'ono kwa kuthamanga), phokoso lochepa, kutsekeka ndi nthunzi, kutentha kwapakati kwambiri, kutentha kochepa (cryogenic), tikulimbikitsidwa kugwiritsa ntchito valavu ya chipata cha Wedge. Monga makampani opanga magetsi, kuyeretsa mafuta, mafakitale a petrochemical, mafuta akunyanja, uinjiniya wopereka madzi ndi uinjiniya wochizira zimbudzi m'mafakitale omanga m'mizinda, makampani opanga mankhwala ndi madera ena.
