s3, when the butterfly plate (25) is seriously worn due to impact and needs to be maintained, the fixing screw (20) is rotated, the sleeve (10) is screwed out, the sleeve (10) drives the second rectangular rod (29) to be screwed out, at the moment, the sliding circular plate (11) vertically moves downwards under the action of gravity and the action of the elastic force of the second spring (7), the sliding circular plate (11) drives the third rectangular rod (30) to vertically move downwards, the top of the third rectangular rod (30) is not clamped with the second rectangular hole (31), at the moment, the butterfly plate (25) can be directly pushed out from the inside of the valve body (8), a new butterfly plate (25) is put in, the fixing screw (20) is screwed again, so that the second rectangular rod (29) is clamped into the third rectangular hole (32), the third rectangular rod (30) is pushed into the second rectangular hole (31), and the connection between the first valve rod (24) and the second valve rod (28) is completed again, the installation is accomplished, easy operation reduces the change time.
