Detailed ways

As shown in Fig. 1 and Fig. 2, the technical characteristics adopted by a water-gas linkage valve with a gas pressure stabilizing valve of the present invention are: it includes an air intake pipe 9, a solenoid valve cavity 10, a micro switch 12, and a water valve device 13. Linkage valve device 14, water inlet pipe 15, air regulating valve core 4, water regulating valve core 16, the air inlet pipe 9 communicates with the electromagnetic valve cavity 10, and the key point is that the air outlet of the electromagnetic valve cavity 10 is connected to the pressure stabilizing valve The air inlet chamber 1 is connected. When the solenoid valve is not powered, the sealing head of the valve core is blocked on the air outlet, and the air outlet is closed to seal off the gas passage between the solenoid valve chamber 10 and the pressure stabilizing chamber 2; Pressure valve 11 The air intake chamber 1 communicates with the pressure stabilizing chamber 2, the stabilizing chamber 2 is connected to one end of the stabilizing membrane 6, and the other end of the stabilizing membrane 6 is connected to the stabilizing valve 11; the stabilizing membrane 6 is connected to the stabilizing valve core 5, the other end of the pressure stabilizing valve core 5 is provided with a conical cap body 51 and placed in the air inlet of the air flow regulating chamber 3 to automatically adjust the opening of the air inlet. In this specific embodiment, the adjusting device 7 is an adjusting nut, and the voltage stabilizing device 8 is a voltage stabilizing spring.

When working, first open the cold water valve leading into the water heater, tap water enters the water valve device 13 from the water inlet pipe 15, and under the promotion of water pressure, the linkage valve device 14 and the micro switch 12 are opened, and the micro switch 12 acts to control A signal from the controller, the controller will start working according to the program. At this time, the gas enters the pressure-stabilizing valve inlet chamber 1 and the pressure-stabilizing chamber 2 after passing through the intake pipe 9 and the opened solenoid valve 10, and the gas pressure pushes the pressure-stabilizing film 6 to automatically adjust the opening of the voltage-stabilizing valve core 5, so that the gas entering The gas flow rate of the gas flow regulating chamber 3 is effectively controlled according to requirements, so as to achieve the stability of gas pressure output. The gas after the pressure stabilization enters the open linkage valve 14 through the gas regulating valve core 4, and finally enters the burner to ignite and burn, so that the water heater works normally. The adjusting nut in the pressure stabilizing valve 11 can be adjusted before leaving the factory according to different gas types and air pressures in various places; it is by adjusting the compression ratio of the voltage stabilizing spring to achieve the stability of the gas water heater under different gas types and air pressure states. Pressure effect, so that the gas water heater is always in good working condition.
