Title:
TRANSMISSION MEMBER, VALVE DRIVING ASSEMBLY, AND VALVE
Document Type and Number:
WIPO Patent Application WO/2022/126732
Kind Code:
A1
Abstract:
A transmission member, a valve driving assembly (100), and a valve (10). The valve (10) comprises the valve driving assembly (100), and the transmission member can be applied to the valve driving assembly (100). The valve driving assembly (100) comprises a first transmission member (110), a second transmission member (120), and a driving member (140). The first transmission member (110) is configured to detachably connect to a rotating shaft (210) of the valve (10); the second transmission member (120) is in transmission connection with the first transmission member (110) and can move relative to the first transmission member (110) in the axial direction of the rotating shaft (210); and the driving member (140) is used to drive the second transmission member (120) to rotate so as to drive the first transmission member (110) and the rotating shaft (210) of the valve (10) to rotate. In the valve driving assembly (100), even if the rotating shaft (210) moves axially during rotation, the first transmission member (110) can move along with the rotating shaft (210), and can always remain matched with the second transmission member (120) to achieve transmission between the two. Therefore, the valve driving assembly (100) can adapt to the axial displacement of the rotating shaft (210), and has good adaptability.
