Embodiment Construction
[0102] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the following examples.
[0103] see figure 1 It should be understood that the embodiment of the present invention provides a zero-cooled water gas water heater system, including a circulating water heater 200 , a self-regulating check valve assembly 100 and a water terminal 300 . Wherein, the circulating water heater 200 has a first cold water connection port 220 and a first hot water connection port 210 , cold water enters through the first cold water connection port 220 , and is output through the first hot water connection port 210 after being heated in the circulating water heater 200 . The water end 300 has a second cold water connection port 320 and a second hot water connection port 310; the water end 300 can be a faucet. The self-regulating one-way valve assembly 100 includes four ports, respectively connected to the first cold wate...

The invention discloses a self-regulating one-way valve assembly of a circulating water heater and a zero-cold water gas water heater system, belonging to the technical field of zero-cold water gas water heaters. The self-adjusting one-way valve assembly includes an interface tube, a one-way valve, a first magnetic part, a slide rod and a second magnetic part. One end of the interface tube has a first port and a second port connected to each other, and the other end has a first port connected to the second port. The three ports and the fourth port, the one-way valve is fixed in the middle of the port pipe; the first magnetic part is fixed on the spool of the one-way valve, the sliding rod is fixed in the port pipe, and the moving direction of the sliding rod is perpendicular to the moving direction of the spool ; The second magnetic part is fixed on the slide bar, and the opposite end of the second magnetic part and the first magnetic part is a magnetic pole with the same name. The invention realizes the automatic connection of the second interface and the fourth interface under the action of the water flow, so as to realize the automatic opening of the circulation loop.
Description
technical field [0001] The invention relates to the technical field of zero cold water gas water heaters, in particular to a self-regulating check valve assembly of a circulating water heater and a zero cold water gas water heater system. Background technique [0002] The zero-cold water gas water heater system is equipped with a circulation loop. When no water is used, the circulation water heater will automatically start to heat the water in the circulation loop. The water comes out first, thereby achieving zero cold water. The reliability of the structure at the junction of the hot water pipe and the return pipe directly affects the effect of zero cold water, but in the prior art, the interface at the junction of the hot water pipe and the return pipe is unreliable, resulting in poor self-starting of the circulation loop and poor circulation flow rate. Small. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a...
