Abstract
A multi-outlet channel combination gas valve includes a valve body, a solenoid valve and a flow regulating mechanism. The valve body has a multiple of air outlets, at least two outlet channels formed between each air outlet and an air inlet of the valve body, a regulating port disposed in the at least two outlet channels, and the flow regulating mechanism can regulate the gas flow passing through each regulating port of the valve body at the same time, and a solenoid valve with a dual-coil electromagnet structure. When the valve is opened, a relatively larger current is passed, and then a very small current will be provided thereafter to maintain an operation by low power consumption. Therefore, this gas valve can be used without a mains power, and a low-level regulating structure is provided for presetting a low-level flow of each air outlet.
