TECHNICAL FIELD

[0001] The utility model relates to the technical field of valve body performance detection, specifically, relate to a waterproof breather valve performance detection device. BACKGROUND

[0002] The waterproof breather valve is a device installed on the product shell, which has air pressure balance and waterproof performance. The waterproof breather valve is usually composed of a waterproof membrane, a breather membrane and a bearing glue, and the breather principle mainly depends on the selective screening effect of the breather membrane. The breather membrane usually adopts a microporous structure or a thin film pore structure. These small pores can screen gas molecules and allow water vapor and other small molecule gases to pass through the membrane hole. At the same time, it prevents external water droplets from entering. This feature allows the waterproof breather valve to maintain internal dryness while achieving air pressure balance with the external environment.
