The present invention relates to a flow control valve for a heating hot water distributor, and more particularly, to a flow control valve for a heating hot water distributor provided with a diffusion space part between the inlet part of the valve body and the flow control part.

In Korea's ondol-style houses, the bottom of the room is heated to heat the ondol that makes up the room, and the warmth of the bottom convections to the top, thereby heating the room. The modern ondol structure consists of a structure in which pipe piping is installed at the bottom of the room floor, and the hot water heated by the boiler is circulated through the pipe, and the room floor is heated through heat transfer between the hot water and the room floor.

As shown in Fig. 1, the ondol type heating structure includes a heating facility such as a boiler 1010 that heats hot water; A pipe 1040 installed on the lower surface of the room to heat the plurality of rooms R1, R2, and R3 and having a circulation structure through which water can be circulated; A water supply unit 1020 for supplying hot water from the boiler 1010 to the pipe 1040; And a water return unit 1030 through which the water circulated in the pipe 1040 is returned again.

In the ondol type heating structure, in order to control the temperature of the hot water supplied from the boiler to the plurality of rooms, a heating distributor is used as shown in FIG. 2.
