Embodiment Construction
[0052] The present invention will be further described by means of embodiments below in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.
[0053] Such as figure 1 As shown, the gas water heater system 100 includes a gas water heater 110 , a water end 120 , a one-way valve 140 and a cold water supply end 130 .
[0054] The water end 120 is generally in the form of a faucet, and the water end 120 has a cold water interface and a hot water interface.
[0055] The cold water supply end 130 is used for supplying cold water, and the cold water here refers to the cold water that has not been heated by the gas water heater 110 , and does not mean that its temperature must be lower than a certain value. The cold water supply end 130 is generally a municipal water supply system.
[0056] "Connected" herein includes fluid communication through tubing.
[0057] The one-way valve 140 is arranged in the pipeline connect...

The invention discloses a one-way valve and a gas water heater system containing the same. The one-way valve includes: a casing, a valve plug arranged in the casing, a linkage mechanism, and a resistance member; the casing has a first fluid outlet and a second fluid outlet. The fluid outlet; the valve plug is arranged between the first fluid outlet and the second fluid outlet and is used to open and close the main channel between the first fluid outlet and the second fluid outlet; the resistance member is arranged at the second fluid outlet; the linkage mechanism is respectively connected The valve plug and the resistance member, wherein the linkage mechanism is configured to drive the resistance member to switch from the first position to the second position when the valve plug opens the main channel. The one-way valve prevents the resistance of the water outflow from being too small when the second fluid outlet of the one-way valve is outflowed. The gas water heater system using the check valve can avoid accidental start-up of the water heater due to the resistance of the cold water interface at the water end being smaller than the resistance of the hot water interface.
Description
technical field [0001] The invention relates to the field of water heaters, in particular to a check valve and a gas water heater system including the same. Background technique [0002] The working principle of the water heater with zero cold water function (circulating water heater without return pipe) and its water system is: when the user is not in the process of using hot water, the water heater will start the water heater when it detects that the water temperature in the pipeline is lower than the set temperature. The built-in circulating water pump, after the water pump is running, the water in the pipeline will flow into the water heater for heating, until the water in the pipeline is heated to the specified temperature, the water pump will stop running, and the water heater will also stop working. [0003] Households that do not have return water pipes, at present, when installing gas water heaters, they will find the faucet at the farthest end of the waterway in th...
