Actuator and reversing valve

Disclosed is an actuator which acts on a valve core rod (21), wherein the actuator (31) is provided with a guide surface (32); and a guide path (333) is formed on the guide surface (32). The guide surface (32) is configured to slidably abut against the top end of the valve core rod (21) such that th...

Beschreibung
Zusammenfassung:	Disclosed is an actuator which acts on a valve core rod (21), wherein the actuator (31) is provided with a guide surface (32); and a guide path (333) is formed on the guide surface (32). The guide surface (32) is configured to slidably abut against the top end of the valve core rod (21) such that the top end of the valve core rod (21) can selectively abut against positions at different heights on the guide path (333), so as to adjust the position of the valve core rod (21) in a valve port (11) of a reversing valve (100) and thereby change the through-flow area of the valve port (11). A reversing valve is further disclosed. The actuator can switch the flow direction of a liquid, and can change the through-flow cross-sectional area of an internal flow channel at different valve ports in communication with the same inlet and thereby perform flow distribution for the liquid entering from the inlet.
