Yintoni ivalve yokujonga ipiston yentsimbi?

Ivalve yokujonga ipiston yentsimbiis eyilelwe ukuthintela ukuguqulwa kokuhamba kwindlela yokubhobhoza.isetyenziswa ngokuqhelekileyo kwiinkqubo zemibhobho apho iivalvu zeglowubhu zisetyenziswa njengevalve yokulawula ukuhamba.Zineendawo zokuhlala ezifanayo njengeevalve zeglobhu.Iivalve zokujonga i-lift zifanelekile ukufakwa kwimigca ethe tye okanye ethe nkqo kunye nokunyuka okunyukayo.

Ziyacetyiswa ukuba zisetyenziswe kunye nomphunga, umoya, igesi, amanzi, kunye nemigca yomphunga enesantya esiphezulu sokuhamba kwe-velocities.i-valve zokujonga i-lift ziqhele ukuyilwa ngentwasahlobo, ivalwe ngokungagqibekanga, ifuna uxinzelelo olungakumbi lokuvula ucango lwazo kunye nokuvumela ulwelo ludlule.

Ivalve yokujonga ipiston yentsimbi sisivalo esithintela umgca wokufunxa ukuba usebenze ungenanto, umz. emva kokuba impompo imisiwe.Ukukhupha impompo ngaphambi kokuba kuqale kwakhona akusafuneki. Phakamisa iivalvu zokujonga

Iimpawu eziphambili zeCast steel piston check valve

Iimpawu kunye neenzuzo zeIvalve yokujonga ipiston yentsimbi

I-1) Ukuvala ngokukhawuleza kunye nokusebenza okuzinzileyo: i-stroke encinci ye-valve disc yenza ukuba kube lula ukuvala ngokukhawuleza, i-spring elayishiwe i-disc idibanisa, yenza ukuvala ngokukhawuleza kwaye kuthembekile.
2) Ukuvala ngokuzenzekelayo nge-spring elayishiwe idiski.
3) Ulwakhiwo olulula kakhulu kunye nokugcinwa lula.
