Device to change kind of gas in gas device
专利汇可以提供Device to change kind of gas in gas device专利检索，专利查询，专利分析的服务。并且PURPOSE: To change the kind of gas easily only by opening or closing a stop valve by providing a stop valve in the gas circuit with a nozzle and inserting an orifice in a bypass circuit which goes round the stop valve and specifying the diameters of the nozzle and orifice.
CONSTITUTION: When a gas of a low calorific value is burned, a stop valve 11 is opened and the gas is supplied to a gas burner B from a gas circuit 1 to bun it. And, at the same time, an air suction fan F is driven to supply the combustion air. On the other hand, when the kind of gas is changed to a gas of a high calorific value, the stop valve 11 is closed. Then the gas goes through a bypass circuit 12 and is supplied to a nozzle N. At this time the gas volume that is set by an orifice 13 inserted into the bypass circuit 12 is set smaller than the gas volume set by a nozzle N and at a value suitable for the gas of a high calorific value. The adjustment work at the time of changing the kind of gas can be, therefore, made easily by opening or closing the stop valve 11.
