The invention discloses a circulating valve and a circulating water heater comprising the same. The circulating valve comprises a body, a flexible film and a sealing element, wherein a cold water port, a water return port and a water outlet are formed in the body, and the cold water port separately communicates to the water return port and the water outlet; the first side of the flexible film communicates to the cold water port and the second side of the flexible film communicates to the atmosphere; the sealing element is connected to the flexible film and the sealing element moves between a first position and a second position along with deformation of the flexible film; at the first position, the sealing part plugs an outward channel of the water return port; and at the second position,the sealing element opens the outward channel of the water return port. By way of self deformation of the flexible film, a water return pipeline is opened and closed circularly automatically, and therefore, a condition that the water inlet temperature becomes higher as hot water is extracted back to the water heater is avoided, the pressurizing effect is improved, and the temperature of the hot water is controlled more accurately.
Description
technical field [0001] The invention relates to a circulation valve and a circulation water heater including the same. Background technique [0002] At present, the main function of the circulating water heater without a return pipe is to use the circulating pump to pump the cold water in the pipeline back to the water heater for heating, so that when the user boils the water, it becomes hot water. When using its circulation pump to pressurize the water flow, the effect of the pressurization is not obvious due to the influence of the circulation loop. When the hot water is turned on at the water point, the cold water enters the water heater, and the circulating pump is turned on at this time. Due to the return water path, part of the hot water is pumped back to the water heater through the return water path. The pressurization effect is not obvious, and the hot water from the water point does not increase much. , At the same time, because part of the hot water is pumped bac...
