Description

AUTOMATIC CONTROL VALVE FOR HEATING}

The present invention relates to an automatic regulating valve for heating, and more particularly, to an automatic regulating valve capable of finely adjusting the opening degree in an open state as well as being openable and open according to an operation signal of a temperature controller.

In general, a hot water distributor used for heating a house is provided with a valve for supplying or cutting off hot water to each room, and the valve is equipped with an actuator electrically connected to a thermostat and operating according to a set temperature. Therefore, the valve can be controlled by the driver according to the set temperature, and regulates the hot water supply through opening and closing.

However, such a valve only supplies or shuts off hot water by the operation of the actuator, and it is difficult to precisely control the flow rate according to the size of each room, thereby limiting energy saving and balanced heating.

In order to overcome this functional limitation, a flow control valve for controlling the flow rate of hot water supplied to each room should be installed in the supply pipe or the return pipe of the hot water distributor. Given the installation in one space, not only space constraints, but also to bear the economic burden of having a separate flow control valve.

In addition, due to the characteristics of the flow control valve, the valve body structure must have the shape of a globe valve. Since the globe valve must reduce the inflow flow path to form the flow control portion, noise is generated due to the orifice phenomenon caused by the reduced flow path. Problem occurs.
