Abstract

L'invenzione concerne una valvola di ritegno, da utilizzarsi specialmente in qualità di valvola di ritegno ad inserzione, comprendente una sede valvolare ed un elemento valvolare che per mezzo di una molla valvolare è precaricato elasticamente nei confronti della sede valvolare. Secondo l'invenzione è previsto un elemento di fissaggio, che è eseguito specialmente in qualità di staffa di fissaggio e che sostiene l'estremità della molla valvolare opposta rispetto all'elemento valvolare ed è elasticamente bloccabile in una rientranza, specialmente in una scanalatura anulare del corpo della valvola. In seguito a ciò viene reso possibile un montaggio veloce e semplice della valvola di ritegno partendo dai suoi singoli componenti.(Figura 1).
