Abstract:
Disclosed is a ball valve, including a drive mechanism (10), a transmission mechanism (12), a valve body assembly (11) and a valve core component (13). The transmission mechanism (12) is configured to drive the valve core component (13) to act through the drive mechanism (10). The valve body assembly (11) includes a first valve body component (4) and a second valve body component (6). The first valve body component (4) is fixedly connected to the second valve body component (6). The valve body assembly (11) is formed with a containing cavity (50, 65). The transmission mechanism (12) includes a first gear ring (22), and at least part of the valve core component (13) is fixedly connected to or in position-limiting fit with the first gear ring (22). The valve core component (13) includes a platform part (131) and a plane part (132). The platform part (131) is located at or adjacent to a rotating center of the valve core component (13). One side of the first gear ring (22) facing toward the valve core component (13) abuts against the platform part (131), and the one side of the first gear ring (22) facing toward the valve core component (13) keeps a preset distance from the plane part (132).
