Abstract

A recirculation valve includes a housing including a hot water fluid passage which is used to allow the hot water to flow through, a cold water fluid passage to allow the cold water to flow through, and a recirculation fluid passage to allow the hot water in the hot water fluid passage to flow into the cold water fluid passage, a water pressure plate provided to close the recirculation fluid passage when the cold water or the hot water is used, and to open the recirculation fluid passage when the cold and hot waters are not used, and a bimetal plate configured to open the recirculation fluid passage as the bimetal plate is spaced apart from a recirculation opening and to close the recirculation fluid passage by making contact with the recirculation opening, and positioned downstream of therecirculation opening in a direction in which the hot water flows.

Description

technical field [0001] The invention relates to a hot water recirculation valve and a hot water recirculation system utilizing the recirculation valve. Background technique [0002] In order to always supply hot water at a temperature above a certain temperature, hot water can circulate in the hot water supply system even when hot water is not flowing out, and the boiler keeps heating. [0003] However, in this type of recirculation system, the hot water continues to flow into the cold water pipe as it continues to be heated. During this process, it is necessary to block the continuous flow of hot water into the cold water pipe, and the impact force that occurs during the process of blocking the flow of hot water into the cold water pipe will act on the pipes and other fittings, thereby accumulating fatigue. [0004] In addition, when users use hot and cold water, they do not want to use the tap to supply high-temperature hot water. When the hot water reaches a temperature ...
