Abstract

본 발명은 물이나 가스를 공급할때의 유량을 조절하는 유량제어밸브와, 이 유량제어밸브를 사용하는 특히 급탕장치에 관한 것으로서, 열교환기를 우회하는 바이패스로에 유량제어밸브를 설치하고, 이 유량 제어밸브의 개방도에 의해 출탕온도를 제어하는 급탕기에 있어서, 유량제어밸브의 전류에 대한 유량의 변화를 직선으로 하는 스프링정수가 비선형인 탄성체를 구비한 동시에 비통전시에는 유량제어밸브를 완전개방이 되도록 구성하고, 급탕정지시에는 소정의 지연시간후에 유량제어밸브를 완전패쇄로 하도록 제어하므로, 급탕의 개시시나 재출탕시 등의 과도적인 탕온변화를 작게 할 수 있고 샤워등의 쾌적한 급탕을 제공할 수 있다. 또 정전이나 고장시등에 열탕이 토출되는 일이 없기 때문에, 안전한 급탕을 제공할 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow rate control valve for adjusting a flow rate when supplying water or gas, and particularly to a hot water supply apparatus using the flow rate control valve, wherein a flow rate control valve is provided in a bypass passage bypassing a heat exchanger. In a hot water heater, which controls the tapping temperature by the opening of the control valve, a spring constant having a linear change in flow rate with respect to the current of the flow control valve is provided with a nonlinear elastic body, and the flow control valve is completely opened during non-energization. When the hot water stop is stopped, the flow control valve is controlled to be completely closed after a predetermined delay time, thereby making it possible to reduce excessive hot water temperature change at the start of hot water supply or when re-water tapping is performed and to provide a comfortable hot water supply such as a shower. Can be. In addition, since hot water is not discharged at the time of power failure or failure, safe hot water supply can be provided.
