Specifically, the declaration device of the gas water heater can have three working conditions, (1) no steady flow, (2) primary steady flow (for example, steady flow rise 7L), and (3) secondary steady flow (for example, steady flow rise 11L);
the secondary steady flow is provided: when the gas water heater works normally, the sliding block drives the coil to electrify, the sliding block is far away from the MK steady flow valve under the thrust of the sliding block spring, at the moment, the corresponding channel is opened, and the MK steady flow valve does not work. The coil of the water electromagnetic valve is electrified, the sealing piston closes the corresponding channel under the action of the push rod, and the main flow stabilizing valve works at the moment. The pressure-bearing disc of the main flow-stabilizing valve can move downwards when the water pressure is high, the distance from the pressure-bearing disc to the base is reduced, the strain spring of the main flow-stabilizing valve can be thinned under the action of pressure, the internal channel is thinned to increase the flow passage resistance, and the flow-stabilizing effect is achieved.
No steady flow exists: when the gas water heater is in a pressurizing or circulating state, the sliding block drives the coil to be electrified, the sliding block is far away from the MK flow stabilizing valve under the thrust action of the sliding block spring, at the moment, the corresponding channel is opened, and the MK flow stabilizing valve does not work. The coil of the electromagnetic valve is powered off, the sealing piston opens the corresponding channel under the action of the return spring, and the steady flow assembly does not work at the moment, so that the two channels are ensured to be opened, and the supercharging flow and the circulating flow are kept at larger values.
Has the primary steady flow: the slide block driving coil is not electrified, the slide block is close to the MK steady flow valve under the thrust of the slide block spring, at the moment, the corresponding channel is closed, and only the other channel can be moved. At this time, the primary steady flow is intervened to work, and the maximum flow is determined by the primary steady flow valve and is only 7L.
According to the embodiment, the working states of the slider driving coil and/or the water valve and the main flow stabilizing valve are controlled according to the obtained comparison result of the current water flow and the preset water flow of the gas water heater, so that the water temperature of the gas water heater reaches the preset water temperature, the water flow can be adjusted according to the requirements, the problem that the water temperature is too high or too low is solved, and the use experience of a user is improved.
