PRESSURE RELIEF TYPE ONE-WAY VALVE DEVICE

WIPO Patent Application WO/2018/166041

A1

Disclosed is a pressure relief type one-way valve device, inside a valve body (10) thereof being a first port (11) and a second port (12) connected to each other, and a channel between the two ports being a pressurized channel (13). A pressurization control device is mounted at the first port (11). There is a pressure relief opening (14) connected to the pressurized channel (13) on a side of the valve body (10), and a pressure relief control device is mounted at the pressure relief opening (14). The pressurized control device comprises a closing element (22) and a sealing element (23). The sealing element (23) having a pressurized via hole (24) connectable to the pressurized channel (13) is fixed at the end face of the first port (11). The closing element (22) is movably mounted inside the pressurized channel (13), and the diameter of the closing element (22) is greater than the aperture of the pressurized via hole (24) and less than the diameter of the pressurized channel (13) at the position thereof. The one-way valve device has a higher reliability, can increase the maximum of the air pressure in a container and helps to save on costs.
