Yintoni i-DIN EN yokujonga ivalve?

DIN EN ivalve yokujongais 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.

ADIN EN ivalve yokujongasisivalo esithintela umgca wokufunxa ukuba usebenze ungenanto, umz. emva kokuba impompo imisiwe.Ukukhupha impompo ngaphambi kokuba kuqale kwakhona akusafuneki. Phakamisa iivalvu zokujonga

Iivalvu zetshekhi zentsimbi ezifakwe emthonjeni zinokufakwa kwimibhobho phantse kuyo nayiphi na indawo yokuxhoma.Xa kuthelekiswa neevalve zokujonga ujingi, iilahleko zentloko yazo ziphezulu njengoko ukuphambuka kokuhamba kubaluleke kakhulu. iidayamitha ezincinci ezincinci.

Iimpawu eziphambili ze-DIN EN zokujonga i-valve

Iimpawu kunye neenzuzo zeDIN EN ivalve yokujonga

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.
