M'malo mwake, valavu yowongolera magetsi yagwiritsidwa ntchito kwambiri m'mafakitale ndi migodi. Vavu yowongolera magetsi nthawi zambiri imapangidwa ndi chowongolera magetsi cha angular stroke ndi valavu ya gulugufe kudzera mu kulumikizana kwa makina, mutakhazikitsa ndi kukonza zolakwika. Vavu yowongolera magetsi malinga ndi gulu la machitidwe: mtundu wa switch ndi mtundu wa regulation. Izi ndi zina mwa kufotokozera kwa valavu yowongolera magetsi.
Pali mfundo ziwiri zazikulu pakukhazikitsa valavu yamagetsi yowongolera mpira
1) Malo oyika, kutalika ndi komwe kulowera ndi kutuluka kwa madzi ziyenera kukwaniritsa zofunikira pa kapangidwe kake. Njira yolowera madzi pakati iyenera kugwirizana ndi njira ya muvi wolembedwa pa thupi la valavu, ndipo kulumikizana kuyenera kukhala kolimba komanso kolimba.
2) Musanayike valavu yowongolera magetsi, muyenera kuyang'ana mawonekedwe ake, ndipo dzina la valavu liyenera kutsatira muyezo wadziko lonse wa "manual valve mark" GB 12220. Pa valavu yokhala ndi kuthamanga kogwira ntchito kopitilira 1.0 MPa ndi ntchito yodulira pa chitoliro chachikulu, kuyesa kwa mphamvu ndi kulimba kuyenera kuchitika musanayike, ndipo valavuyo ingagwiritsidwe ntchito pokhapokha itavomerezedwa. Pa nthawi yoyesa mphamvu, kuthamanga koyesa kuyenera kukhala nthawi 1.5 ya kuthamanga kodziwika, nthawi yake siyenera kupitirira mphindi 5, ndipo chipolopolo cha valavu ndi kulongedza ziyenera kuvomerezedwa ngati palibe kutuluka.
Malinga ndi kapangidwe kake, valavu yamagetsi yowongolera mpira imatha kugawidwa m'magawo awiri: mbale yotsekedwa bwino, mbale yoyimirira, mbale yopendekera ndi mtundu wa lever. Malinga ndi mawonekedwe otsekera, imatha kugawidwa m'magulu awiri: mtundu wotsekedwa bwino ndi mtundu wotsekedwa mwamphamvu. Mtundu wotsekedwa wofewa nthawi zambiri umatsekedwa ndi mphete ya rabara, pomwe mtundu wotsekedwa wolimba nthawi zambiri umatsekedwa ndi mphete yachitsulo.
Malinga ndi mtundu wa kulumikizana, valavu yamagetsi yowongolera mpira imatha kugawidwa m'magulu olumikizirana a flange ndi olumikizirana a pair clamp; malinga ndi njira yotumizira, imatha kugawidwa m'magulu awiri: manual, gear transmission, pneumatic, hydraulic ndi electric.
Kukhazikitsa ndi kukonza valavu yamagetsi yowongolera mpira
1. Pa nthawi yoyika, diski iyenera kuyima pamalo otsekedwa.
2. Malo otsegulira ayenera kutsimikiziridwa malinga ndi ngodya yozungulira ya mpira.
3. Pa valavu ya mpira yokhala ndi valavu yodutsa, valavu yodutsa iyenera kutsegulidwa musanatsegule.
4. Vavu yamagetsi yowongolera mpira iyenera kuyikidwa motsatira malangizo oyika a wopanga, ndipo valavu yolemera ya mpira iyenera kukhala ndi maziko olimba.
