Problems solved by technology
Existing standards require that there must be two sealing structures in the gas appliance, but in the valve structure of the combination of proportional valve and stop valve used in the related art, the gas outlet of the proportional valve has a direct connection to the gas channel of the inner ring or outer ring of the stove. , so that there is only one sealing structure in this road. In order to meet the standard requirements, it is necessary to arrange a stop valve on the main air intake pipe, which makes the gas valve of the complete gas appliance have many parts, high production cost and reliable gas valve. In addition, there are many sealing ports of the whole machine, which increases the hidden danger of air leakage
And due to the existence of the shut-off valve in the main intake pipe, the length of the main intake pipe is longer, which also increases the cost

The embodiment of the present invention relates to a gas valve and a gas appliance. The gas valve includes a cock valve having a first cock valve air inlet, a second cock valve air inlet, a cock valve connection port and at least one cock valve air outlet; proportional valve air inlet, the first proportional valve air outlet, and the proportional valve of the second proportional valve air outlet; wherein, the proportional valve air inlet is only directly connected with the cock valve connection port, and the second proportional valve The air outlet is only in communication with the air inlet of the second plug valve. In the embodiment of the present invention, the cock valve and the proportional valve are used in combination to realize a two-way sealing structure, which meets the standard requirements. There is no need to set a stop valve on the main air intake pipe of the gas appliance, which reduces the parts of the gas valve and reduces the overall cost. The sealing port of the machine increases the reliability and reduces the cost. The gas appliance adopting the gas valve of the embodiment of the present invention can realize precise control of the burner flame through the cooperation of the proportional valve and the cock valve.
Description
technical field [0001] The invention relates to the field of gas appliances, in particular to a gas valve and a gas appliance. Background technique [0002] The gas valve is the core control part of the gas appliance, which is used to realize the on-off of the gas pipeline or the adjustment of the gas intake volume. Existing standards require that there must be two sealing structures in the gas appliance, but in the valve structure of the combination of proportional valve and stop valve used in the related art, the gas outlet of the proportional valve has a direct connection to the gas channel of the inner ring or outer ring of the stove. , so that there is only one sealing structure in this road. In order to meet the standard requirements, it is necessary to arrange a stop valve on the main air intake pipe, which makes the gas valve of the complete gas appliance have many parts, high production cost and reliable gas valve. In addition, there are many sealing ports in the w...
