The invention relates to a reversing valve. The reversing valve comprises a valve body, a valve element assembly and an actuating assembly, wherein an inlet, at least two outlets and internal flow channels communicating the inlet and the outlets are formed in the valve body; a valve port matched with the valve element assembly is formed in each internal flow channel; the valve element assembly is movably arranged on the valve body; the actuating assembly is used for actuating the valve element assembly so that the inlet can selectively and completely communicate with one outlet or simultaneously and partially communicate with the multiple outlets, and flow distribution is achieved by adjusting the through-flow sectional area of the valve ports. A fluid distribution body is formed on each internal flow channel, and a separation barrel is arranged in each fluid distribution body so as to divide the fluid distribution body into a first accommodating cavity and a second accommodating cavity; the valve port is formed at the opening position of the separation barrel; and the first accommodating cavity communicates with the second accommodating cavity through the valve port, one of the first accommodating cavity and the second accommodating cavity always communicates with the inlet in each internal flow channel, and the other one always communicates with the outlet in each internal flow channel.

    本公开涉及一种换向阀,该换向阀包括阀体、阀芯组件和致动组件,阀体上形成有进口、至少两个出口以及将进口与每个出口连通的内部流道,每个内部流道上均形成有与阀芯组件配合的阀口,阀芯组件可移动地设置于阀体,致动组件用于致动阀芯组件使得进口可选择地与其中一个出口完全连通,或同时与多个出口部分连通并通过调节阀口处的通流截面积实现流量分配。每个内部流道上形成有流体分配体,流体分配体中设置有分隔筒体,以将流体分配体分隔为第一容腔和第二容腔,阀口形成为分隔筒体的开口处,第一容腔与第二容腔之间通过阀口连通,第一容腔和第二容腔其中的一者始终与其所在的内部流道上的进口连通,另一者始终与其所在的内部流道上的出口连通。
