Atunci c\u00e2nd alegem robinete cu bil\u0103, ar trebui s\u0103 \u0219tim ce fel de supape cu bil\u0103 avem nevoie. Supapa cu bil\u0103 este esen\u021bial\u0103 \u0219i vor exista unele probleme de scurgere, cum ar fi defec\u021biunea. Ast\u0103zi v\u0103 voi spune motivele scurgerii supapei cu bil\u0103.<\/p>\n<p>Cauzele scurgerilor interne<br \/>\n1.

Contactul dintre garnitur\u0103 \u0219i flan\u0219\u0103 devine slab din cauza defec\u021biunii de \u00eemb\u0103tr\u00e2nire sau a vibra\u021biilor mecanice.

Supapa din font\u0103 este deteriorat\u0103 dup\u0103 ce a fost lovit\u0103 de obiecte grele.<\/p>\n<p>Cauza scurgerii externe<br \/>\n1. Ambalajul nu este selectat corect, nu este rezistent la coroziune medie \u0219i nu este rezistent la utilizarea presiunii \u00eenalte sau vidului, temperaturii ridicate sau temperaturii sc\u0103zute a supapei.<br \/>\n2.
