Abstract

The invention discloses a balance breather valve which comprises a shell, a first waterproof breathing film and a dynamic sealing structure, wherein a protruding part is arranged on the top surface of the shell; the first waterproof breathing film is fixed at the bottom of the protruding part; the dynamic sealing structure is used for hermitically isolating the first waterproof breathing film from an inner cavity of the shell or communicating the first waterproof breathing film to the inner cavity of the shell; the dynamic sealing structure comprises a driving mechanism, a first sealing body which is hermitically arranged on the shell and surrounds the side wall of the first waterproof breathing film and a second sealing body opposite to the first sealing body along the vertical direction; the first waterproof breathing film is located in a cavity encircled by the first sealing body and the second sealing body; and the driving mechanism drives the second sealing body to move towards or away from the direction of the first sealing body, so that the second sealing body can be hermitically matched with the first sealing body or separated from the first sealing body. In case of an abnormal working condition, the first sealing body and the second sealing body realize sealing to prevent external water vapors from entering a box body, so that components in the box body can operate under constant humidity, and the sealing property of the balance breather valve is improved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a balanced breathable valve. Background technique [0002] The balance vent valve can be applied to electric vehicle battery pack boxes, or high-pressure control boxes, or some sealed boxes that require high air pressure or humidity. Especially in the new energy auto parts pack battery pack, the balance vent valve is installed on the installation surface of the battery pack product. The vent valve can balance the internal and external air pressure balance when the internal pressure of the installation box changes, and the internal air pressure rises sharply. , the internal pressure can be released; at the same time, the breather valve plays the role of sealing and isolating the inside of the installation box from the outside world. [0003] The structure of the existing balance breathable valve is mostly as the balance breathable valve disclosed in Chinese patent document CN10609...
