Abstract

The discloses relates to an actuating piece and a reversing valve. The actuating piece acts on a valve element rod of the reversing valve; the actuating piece is provided with a guide surface; a guide path is formed on the guide surface; the guide surface is used for being pressed against the top end of the valve element rod in a sliding manner, so that the top end of the valve element rod can be selectively pressed against the positions at different heights on the guide path to adjust the position of the valve element rod in a valve port of the reversing valve, thereby changing the flow area at the valve port. According to the technical scheme, the actuating piece can adjust the flow area of the valve port of the reversing valve, so that the flow direction of liquid in the reversing valve can be switched or the flow of the liquid flowing through the reversing valve can be distributed.

Description

technical field [0001] The present disclosure relates to the field of electric vehicle thermal management systems, in particular, to an actuator and a reversing valve. Background technique [0002] The electric vehicle thermal management system includes a coolant circulation system. Some vehicles only have one PTC heater. When the ambient temperature is low, the PTC heater needs to provide heated coolant for the heater core and power battery pack at the same time. , At this time, it is necessary to properly distribute the coolant output by the PTC heater. However, the current electronic water valve has a very complicated structure for controlling the driving part of the valve, and cannot adjust the flow area of ​​the valve, the control and driving effect is poor, and the complexity of the system is high. Contents of the invention [0003] The purpose of the present disclosure is to provide an actuator and a reversing valve, the actuating member can adjust the flow area at...
