Beschreibung
Zusammenfassung:	The invention provides a bypass valve and a gas water heater, and relates to the technical field of water heaters. The bypass valve comprises a valve body, and the valve body is provided with a water inlet channel, a water outlet channel, a first bypass and a second bypass. The first valve element is arranged in the first bypass and used for moving in the direction close to the water outlet channel under the action of water flow, the first reset piece is used for applying acting force to the first valve element, the acting force enables the first valve element to move in the direction away from the water outlet channel, and the driving piece is used for driving the first valve element to rotate in the axial direction of the first bypass. In the process that the second valve element rotates from the first position to the second position, the opening degree of the second bypass is gradually reduced, and the first transmission part is used for acting on the second transmission part and pushing the second transmi
