Abstract:
Disclosed is a control valve, comprising: a valve seat (10), which is provided thereon with a normally open valve port and a plurality of switching valve ports; a bushing assembly, which is sleeved on the valve seat (10); a slider (20), which is rotatably disposed on the valve seat (10), for controlling the opening and closing of the plurality of switching valve ports; a center shaft (30), which is disposed between the valve seat (10) and the bushing assembly, the bottom end of the center shaft (30) being fixed to the valve seat (10), and the slider (20) being rotatably sleeved on the central shaft (30); a rotor member (40), which is sleeved on the central shaft (30), the rotor member (40) including a driving gear (41); an actuating gear (50), which is sleeved on the central shaft (30) and which drives the slider (20) to rotate; a transmission gear, which is disposed between the driving gear (41) and the actuating gear (50), and which meshes with both the driving gear (41) and the actuating gear (50). The control valve solves the issue wherein it is difficult to ensure the concentricity of a driving gear and an actuating gear.
