Problems solved by technology

Since the flow rate is controlled through a continuous feedback process between the flow sensor 40, the control unit 80, and the flow control valve 20 to reduce the flow rate to a desired level, hot water of a desired temperature cannot be quickly supplied to users due to low response speed

Embodiment Construction

[0024] The configuration and operation of a preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] figure 2 is a perspective view illustrating the appearance of the flow control valve according to the embodiment of the present invention. image 3 yes figure 2 An exploded perspective view of the flow control valve shown. Figure 4 yes figure 2 Cross-sectional view of the flow control valve shown.

[0026] The flow control valve 1 includes: a motor 111, which can rotate in both directions; a switch part 154, which reciprocates vertically by the rotation of the motor 111, to control the opening ratio of the passage; a position changing part, whose position is related to the switch by the rotation of the motor 111. The part 154 is integrally changed; and a valve opening ratio sensing unit which senses the opening ratio of the switching part 154 from the output voltage which changes with the posit...

Abstract

The present invention relates to a flow control valve that is capable of rapidly supplying hot water at a user's desired temperature by promptly controlling the opening rate of a valve depending on the flow of supplied direct water. In order to implement this, the flow control valve according to the present invention includes a motor that rotates in both directions; an opening and closing member that reciprocates by rotation of the motor to control the opening rate of a channel; a position varying member of which a position varies integrally with the opening and closing member by the rotation of the motor; and a valve opening rate sensing unit that senses the opening rate of the valve from an output voltage varying depending on the position of the position varying member.

Description

technical field [0001] The present invention relates to a flow control valve, and more particularly, to a flow control valve installed in a boiler or a water heater and capable of controlling the flow of direct water supplied to a heat exchanger. Background technique [0002] Generally, a flow control valve capable of controlling the flow of water supplied through a direct water pipe is provided in a boiler or a water heater that supplies hot water. [0003] figure 1 is a schematic diagram showing a hot water supply system provided with a known flow control valve. refer to figure 1 , the hot water supply system includes: a direct water pipe 10 through which direct water flows; a flow control valve 20 which controls the flow of direct water supplied through the direct water pipe 10; a direct water temperature sensor 30 which senses the The temperature of the direct water at 20; the flow sensor 40, which is used to measure the flow of the direct water flowing through the di...
