Embodiment Construction

[0052] The present invention will be further described below with reference to the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0053] like 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 port and a hot water port.

[0055] The cold water supply end 130 is used to supply cold water, and the cold water here refers to the cold water that has not been heated by the gas water heater 110 , rather than 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 disposed in the pipeline connecting the cold water interface and the hot water in...

Abstract

The invention discloses a one-way valve and a gas water heater system comprising the same. The one-way valve comprises a shell, a valve plug, a linkage mechanism and a resistance component, wherein the valve plug, the linkage mechanism and the resistance component are arranged in the shell; the shell is provided with a first fluid outlet and a second fluid outlet; the valve plug is arranged between the first fluid outlet and the second fluid outlet and used for opening and closing a main flow channel between the first fluid outlet and the second fluid outlet; the resistance component is arranged at the second fluid outlet; and the linkage mechanism is connected with the valve plug and the resistance component and arranged to drive the resistance component to be switched from a first position to a second position when the main flow channel is opened by the valve plug. The one-way valve prevents the water outlet resistance from being too small when water flows out of the second fluid outlet of the one-way valve. The gas water heater system using the one-way valve can avoid accidental starting of a water heater due to the fact that resistance of a cold water connector at a water usingend is smaller than that of a hot water connector.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a one-way 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, when the water heater detects that the water temperature in the pipe is lower than the set temperature, it will start the water heater. The self-contained circulating water pump will make the water in the pipeline flow into the water heater for heating after the water pump runs, 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] For families that do not have a return water pipeline installed, the gas water heater will find the faucet at the farthest end of the waterway in the family dur...
