The purpose of the present invention is to provide a heating water distributor with a proportional control valve capable of precisely controlling the supply amount of heating water in multiple steps according to a heating load using the power of motor. According to the present invention for the above effect, a heating water distributor controlling the flow rate of heating water supplied to each room comprises: a motor (300) of which the rotation amount is controlled in multiple steps by input pulse signals; a primary gear (320) rotated depending on the driving of the motor (300); a flow rate control member (400) on which a secondary gear (420) transmitting the power of the motor (300) when engaged with the primary gear (320) and in which a cam part (450) is formed; a plunger assembly (800) having a valve shaft (911) and a valve stem (912) connected to the lower side thereof, and moved up or down to be linked with the valve shaft (911) and the valve stem (912) when moved up or down according to a contact position between the cam part (450) and the plunger assembly (800); and a distributor body (910) having a heating water flow path formed therein and receiving the heating water returned from each of the rooms, and having an opening (910a) connected to the heating water flow path and having an opening degree controlled by the vertical movement of the valve stem (912), wherein the contact position between the cam part (450) and the plunger assembly (800) is due to the rotation of the flow rate control member (400). |
