Yintoni ivalvu yokujonga i-DIN EN?

Ivalvu yokujonga i-DIN ENmnaYenzelwe ukuthintela ukuguquka kokuhamba kwamanzi kwinkqubo yemibhobho. Isetyenziswa kakhulu kwiinkqubo zemibhobho apho iivalvu zeglobe zisetyenziswa khona njengevalvu yokulawula ukuhamba kwamanzi. Zineendawo zokuhlala ezifanayo neevalvu zeglobe. Iivalvu zokujonga ukuphakama zifanelekile ukufakwa kwimigca ethe tye okanye ethe nkqo enokuhamba okuphezulu.

AIvalvu yokujonga i-DIN ENyivalvu ethintela umgca wokufunxa ukuba ungasebenzi ungenanto, umz. emva kokuba ipompo imisiwe. Ukuyibeka iprimer yepompo ngaphambi kokuba uyiqalise kwakhona akusafuneki. Iivalvu zokujonga ukuphakama

Iivalvu zokuhlola ukuphakama zentsimbi efakwe entwasahlobo zinokufakwa kwimibhobho phantse kuyo nayiphi na indawo yokuyibeka. Xa kuthelekiswa neevalvu zokujonga ukujika, iintloko zazo zilahlekile kakhulu njengoko ukuphambuka kokuhamba kwamanzi kubaluleke kakhulu. Iivalvu zokujonga ukuphakama zikhethwa xa usetyenziso lufuna ububanzi obuncinci.

Iimpawu eziphambili zevalvu yokujonga i-DIN EN

Iimpawu kunye neenzuzo zeIvalvu yokujonga i-DIN EN

1) Ukuvala ngokukhawuleza kunye nokusebenza okuzinzileyo: Ukubetha okuncinci kwediski yevalvu kwenza kube nokwenzeka ukuvala ngokukhawuleza, idiski efakwe entwasahlobo iyinto entle kakhulu, yenza ukuvala kukhawuleze kwaye kuthembeke.
2) Ukuvala ngokuzenzekelayo ngediski efakwe entwasahlobo.
3) Ulwakhiwo olulula kakhulu kwaye kulula ukulugcina.
