Description
Technical field
The utility model relates to the switching device that flows to of industrial fluid foods, and more particularly, the utility model relates in particular to the switch valve equipment that flows to of a kind of industrial flammable liquid and combustion-supporting liquid.
Background technique
But industrial often to use two kinds of differences can synergistic fluid foods (being liquid); in order to make two kinds of liquids enter regularly interaction in certain specific device, obtain certain energy or make certain product, conventionally can adopt and flow to switching device is switch valve.For example: two kinds of relevant liquids often using are flammable liquid and combustion-supporting liquid, and wherein flammable liquid enters in certain stove and accessory, in the presence and proper temperature of combustion-supporting liquid, can discharge heat energy; And for energy-saving and emission-reduction, conventionally by exhaust fluid waste heat, heat certain Preheating unit, adopt again selector valve to make fresh flammable liquid and combustion-supporting liquid periodically by this Preheating unit, implement preheating, and then enter and in corresponding stove and accessory, interact, discharge energy storage, thereby realize energy-saving and emission-reduction.
