Embodiment Construction
[0033] The present invention is further described below by way of example, but not to limit the invention thus described embodiments within the scope of embodiments.
[0034] like Figure 1 - Figure 5 , The present embodiment discloses an embodiment of a circulating valve, such as figure 1 and figure 2 , The circulation valve 1 comprises a body 10, a cold water port 11 is provided on the body 10, the communication between the inlet 13 and return outlet 12, a cold water inlet port 11 and return 13, respectively, and a water outlet 12.
[0035] like figure 1 and figure 2 , The circulation valve 1 according to the present embodiment further includes a flexible membrane 3, the first side of the flexible membrane in communication with cold water port 11 3, a second flexible membrane in communication with the atmosphere side 3; flexible membrane 3 may be of film or other flexible material film can be deformed.
[0036] like figure 1 and figure 2 , The circulation valve of the present emb...

The invention discloses a circulation valve and a circulation water heater including the circulation valve. The circulation valve includes a body, and the body is provided with a cold water port, a water return port and a water outlet. The water outlets are connected; the flexible membrane, the first side of the flexible membrane communicates with the cold water port, and the second side of the flexible membrane communicates with the atmosphere; the seal, the seal is connected with the flexible membrane, The sealing member moves between a first position and a second position following deformation of the flexible membrane, wherein, in the first position, the outward passage of the water return port of the sealing member; In the second position, the sealing member opens the outward passage of the water return port. The present invention automatically realizes the opening and closing of the circulation of the return water pipeline through the self-deformation of the flexible membrane, thereby avoiding the increase of the temperature of the incoming water caused by the hot water pumping back to the water heater, improving the pressurization effect, and making the hot water The temperature control is more accurate.
Description
Technical field [0001] The present invention relates to a circulating water heater comprising a valve cycle thereof. Background technique [0002] Currently no return pipe circulating water heater and its main function is to use the pipeline circulation pump cold water pumped back to the water heater is heated to a boiling water users is hot water. When using a pressurized water flow because of its influence circulation pump cycle causes a supercharging effect is not obvious. When hot water is opened point, cold water enters the water heater, the circulation pump is opened at this time, due to return water, causes a portion of the hot water drawn back by a return water heater, the supercharging effect is not obvious, the point of water increases much hot water , and because part of the hot water heater is withdrawn causing the temperature of water becomes higher, the influence of the temperature control heater. Inventive content [0003] The present invention is to solve the tec...
