摘要： Disclosed is a control valve (10). The control valve comprises a valve body (1) and a flow pre-setting assembly (8). The flow pre-setting assembly (8) comprises an adjusting rod (81), a control component (83) and an adjusting component (82), and the control component (83) is arranged on the bottom side of the valve body (1) in a manner of being capable of rotating around an axis and is connected, in a shape-matching manner, to an end of the adjusting rod (81) which extends out of the valve body (1), so as to drive the adjusting rod (81) to rotate; the adjusting component (82) is arranged in an inner cavity and fixedly connected to the adjusting rod (81), and the adjusting component (82) can be driven by the adjusting rod (81) to rotate between a first position and a second position, so as to set the maximum opening degree of the control valve (10). The control component (83) is provided with an indication part (831) on a surface facing the valve body (1) and/or on a surface facing away from the valve body (1), the deviation of the indication part relative to a reference position can indicate the maximum flow corresponding to the position of the adjusting component (82), the reference position is fixed relative to the valve body (1), the control valve is convenient for an operator to observe and realize flow pre-setting, and the above operation can be completed without disassembling and reassembling an actuator connected to the top of the valve body.

摘要： A connection mechanism for connecting a first component and a second component is provided. The connection mechanism includes a gripping part, a connection part, and a fixing part. The gripping part has a first connection portion and a second connection portion, a pair of first through holes is disposed symmetrically on the first connection portion, and a through slot is disposed symmetrically between the first connection portion and the second connection portion. The connection part has a free end and a fixing end, and the free end passes through the first through hole, so as to limit a radial movement of the connection part. The fixing part passes through the through slot, one end of the fixing part is fixed on the gripping part, and the other end of the fixing part is used to limit an axial movement of the connection part. A valve and an actuating mechanism in cooperation with the connection mechanism are also provided. By employing the connection structure, components connected therewith are conveniently and quickly connected and dismounted.
