Abstract
A kind of sealing valve for vacuum container comprising: the cap body (10), the connecting body (11) and the locking portion (12); the cap body (10) is to be jointed to the locking portion (12) through the connecting body (11); the locking portion (12) is formed with the concave portion (13); the locking portion (12) is to lock onto the hole (22) on the upper cap (20) via the concave portion, thus when the vacuum pump (3) proceeds to extract air out of the vacuum container, the cap body (10) is to be deflected and deformed by air flow, so that the air hole (23) of the upper cap (20) is to be opened, and then the cap body (10) is to automatically close the air hole (23) of the upper cap (20) after the pressure difference between the interior and exterior of the vacuum container has reached the predetermined value.
