Abstract
An actuating member is provided. The actuating member acts on a valve core rod. A guide surface is arranged on the actuating member. A guide path is formed on the guide surface. The guide surface is configured to slidably abut against a top end of the valve core rod, so that the top end of the valve core rod selectively abuts against a position on the guide path at a different height, so as to adjust a position of the valve core rod in a valve port of a reversing valve, thereby changing a flow area at the valve port.
Claims17
An actuating member, comprising:
- a guide surface on the actuating member having a rotating shaft;
- and
- a guide path formed on the guide surface,
- wherein the guide surface is configured to slidably abut against a top end of a valve core rod, so that the top end of the valve core rod selectively abuts against a position on the guide path at a different height, to adjust a position of the valve core rod in a valve port of a reversing valve to change a flow area at the valve port,
- wherein the guide surface comprises two first guide portions disposed at highest portions of the guide surface and two second guide portions disposed at lowest portions of the guide surface, wherein the first guide portions are symmetric with each other with respect to a center of the rotating shaft, the second guide portions are symmetric with each other with respect to the center of the rotating shaft, and the first guide portions and the second guide portions are alternately disposed on the guide surface.
A reversing valve, comprising:
- a valve body;
- a valve core assembly;
- and
- an actuating assembly,
- wherein an inlet, at least two outlets, and an internal flow channel that connects the inlet with the outlets are formed on the valve body;
- a valve port engaged with the valve core assembly is formed on the internal flow channel;
- the valve port is in a one-to-one correspondence with the valve core assembly;
- the valve core assembly is movably arranged on the valve body;
- and the actuating assembly is configured to actuate the valve core assembly, so that the inlet is selectively in communication with at least one of the outlets, and flow distribution is realized by adjusting a cross sectional flow area at the valve port,
- wherein the actuating assembly comprises an actuating member comprising:
- a guide surface on the actuating member having a rotating shaft;
- and
- a guide path formed on the guide surface,
- wherein the guide surface is configured to slidably abut against a top end of a valve core rod of the valve core assembly, so that the top end of the valve core rod selectively abuts against a position on the guide path at a different height, to adjust a position of the valve core rod in the valve port to change a flow area at the valve port,
- wherein the guide surface comprises two first guide portions disposed at highest portions of the guide surface and two second guide portions disposed at lowest portions of the guide surface, wherein the first guide portions are symmetric with each other with respect to a center of the rotating shaft, the second guide portions are symmetric with each other with respect to the center of the rotating shaft, and the first guide portions and the second guide portions are alternately disposed on the guide surface.
A reversing valve, comprising:
- a valve body having an inlet, a plurality of outlets, and an internal flow channel that connects the inlet with the plurality of outlets and includes a valve port;
- a valve core rod movable within the valve port;
- and
- an actuating member having a rotating shaft, an arcuate guide surface, and a guide path formed on the guide surface,
- wherein the guide surface is configured to slidably abut against a top end of a valve core rod, so that the top end of the valve core rod selectively abuts against a position on the guide path at a different height, to adjust a position of the valve core rod in the valve port to change a flow area at the valve port,
- wherein the guide surface comprises two first guide portions disposed at highest portions of the guide surface and two second guide portions disposed at lowest portions of the guide surface, wherein the first guide portions are symmetric with each other with respect to a center of the rotating shaft, the second guide portions are symmetric with each other with respect to the center of the rotating shaft, and the first guide portions and the second guide portions are alternately disposed on the guide surface.
