Abstract

The invention provides a two-gas source gas valve. A gas inlet channel is communicated with the gas inlets of a first gas channel and a second gas channel in a valve body; a containing cavity is arranged on the valve body and is sealed with the second gas channel through a leather diaphragm; a pressure regulation spring is arranged in the containing cavity; a pressure regulation bolt is arranged in the second gas channel and is articulated with the leather diaphragm; a sealing ring is arranged in the second gas channel and is matched with the pressure regulation bolt; a valve core is arranged in the valve body and comprises an upper cavity of the valve core and a lower cavity of the valve core; the upper cavity of the valve core is arranged at the gas outlet of the second gas channel, and the lower cavity of the valve core is arranged at the gas outlet of the first gas channel; and an electromagnetic valve is arranged at the gas inlet channel. According to the invention, nozzles can be selected automatically according to gasses, the manual replacement is not required, and use and operation are convenient.

Description

technical field [0001] The invention relates to a valve, more precisely a double gas source gas valve. Background technique [0002] There is such a valve in the gas industry, which has the function of a switch valve and the nozzle is integrated in the valve, and it is directly connected to the burner when used. Because different gases have different calorific values ​​and different pressures, once the gases are different, corresponding parts such as nozzles need to be replaced. Therefore, the existing valves of this type cannot be directly applied to gas appliances with dual gas sources. [0003] Usually, the gas system is either natural gas or liquefied petroleum gas; since the pressure and calorific value of different gases are different, to achieve the same power, the nozzle sizes required for different gases are different. Therefore, it is necessary to manually replace the nozzle. Contents of the invention [0004] Due to the above-mentioned shortcomings of the pri...
