Title:
EXHAUST VALVE
Document Type and Number:
WIPO Patent Application WO/2020/111057
Kind Code:
A1
Abstract:
An exhaust valve (100) that comprises a casing (1), a valve seat (4), a float receiver (6), and a float (5). When a fluid is not flowing in the casing (1), the float (5) is on the float receiver (6) in an initial position, and the valve port (41) is open. When a gas flows into the casing (1) from an inflow port (31), the float (5) keeps the valve port (41) open and allows the gas to flow out from an outflow port (32). When a liquid flows into the casing (1) from the inflow port (31), the float (5) is lifted by the buoyant force of the liquid, closes the valve port (41), and prevents the liquid from flowing out from the outflow port (32). The initial position of the float receiver (6) can be adjusted by changing the distance therefrom to the valve seat (4).
