Kodi valavu ya Gate ya mafuta ndi chiyani?
Monga ma valve achizolowezi a chipata cha wedge, magawo otsegulira ndi kutseka a valavu ya Gate ya mafuta ndi chipata, chooneka ngati wedge, ndichifukwa chake amatchedwa valavu ya chipata cha wedge. Vavu ya chipata cha wedge imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu ndipo singasinthidwe ndikukokedwa. Vavu ya chipata idapangidwa kuti igwiritsidwe ntchito yotseguka kwathunthu kapena yotsekedwa kwathunthu, chifukwa chifukwa cha mawonekedwe a zotchingira zake zomwe zimakhala ndi mawonekedwe a wedge, ngati itagwiritsidwa ntchito pang'ono, padzakhala kutayika kwakukulu kwa kuthamanga ndipo pamwamba potseka padzawonongeka madzi akakhudzidwa.Chinthu chachikulu cha valavu ya chipata cha DIN-EN wedge ndichakuti malo ake otsekera pakati pa "chipata" ndi mpando wake ndi athyathyathya, zomwe zimapangitsa kuti kuthamanga kwa mpweya kuchepe kwambiri.
