Title:
VALVE CORE AND ONE-WAY VALVE
Document Type and Number:
WIPO Patent Application WO/2023/185916
Kind Code:
A1
Abstract:
A valve core (3) and a one-way valve. The valve core (3) comprises a body (31) and a plurality of wing plates (32). A side surface of the body (31) is provided with at least one variable-diameter portion (314); the plurality of wing plates (32) are arranged on the side surface of the body (31) in a protruding manner, and are arranged at intervals from each other in the circumferential direction of the body (31), and flow channels (61, 62, 63) are formed between every two adjacent wing plates (32); the variable-diameter portion (314) is provided in at least one of the flow channels (61, 62, 63), such that the flow area of the flow channel corresponding to the variable-diameter portion (314) is not equal to the flow area of at least one of the remaining flow channels; and an outer wall surface of the variable-diameter portion (314) and a virtual plane (7) form a line segment (71), radial distances H between each point on the line segment (71) and an axis L of the body (31) are not completely equal, and the virtual plane (7) is perpendicular to the axis of the body (31). In the process of fluid passing through the valve core (3), the magnitudes of forces received by the valve core (3) in the radial direction thereof are not uniform, such that a radial resultant force along the valve core (3) is not zero, and the radial resultant force causes the valve core (3) to abut against an inner wall surface of an inner cavity of the valve body, thereby preventing the valve core (3) from impacting the valve body to generate noise.
