Plug valve with adjustable actuation actuation phases for controlling flow rate by means of plug axial movement

A plug valve with adjustable actuation phases for controlling a flow rate by means of plug axial movement, comprising:

• a power disk, wherein one end of the power disk is matched with an outer spline by an inner spline, the outer spline is connected to a plug body by a valve stem,
• a bearing that supports the power disk during rotation of the power disk,
• a pushing ring is disposed on the valve stem, the pushing ring is clamped in a clamping groove of a pushing fork;
• when moving along the axial direction, the pushing fork drives the outer spline, the valve stem, the pushing ring and the plug body to move along the axial direction;
• the plug body is matched with a valve body and rotates within the valve body, the plug body is provided with a plug special-shaped through hole thereon, the plug special-shaped through hole is provided radially through the plug body, the valve body is provided with a valve through hole thereon, the valve through holes are provided in pairs in each group and radially passes through the valve body;
• and
• the plug special-shaped through hole is of a shape in which a left portion thereof is narrow and a right portion thereof is wide.
