Specifically, as shown in fig. 1 to 3, the adjusting module is connected to the valve body 1 for adjusting the conduction size of the second passage 3 to adjust the size of the small fire state. The adjusting module comprises: an adjusting screw 61 and a flow-through channel 62. The adjusting bolt 61 is in threaded connection with the valve body 1, the adjusting bolt 61 cuts off the second passage 3, the second passage 3 is divided into an air inlet section 31 and an air outlet section 32, the air inlet section 31 is communicated with the air inlet 11, and the air outlet section 32 is communicated with the air outlet 12; the flow-through channel 62 is arranged on the adjusting bolt 61, and the flow-through channel 62 is communicated with the air inlet section 31 and the air outlet section 32. During the use, through the entering position of adjustment bolt 61, realize the regulation of the size that switches on of second passageway 3, and then realize the regulation of little fiery state size, when adjusting bolt 61 twists completely, the gas only circulates between inlet segment 31 and the section 32 of giving vent to anger through circulation stack 62, carries the gas of minimum flow, when adjusting bolt 61 not twists completely, the gas can circulate between inlet segment 31 and the section 32 of giving vent to anger through circulation stack 62, adjusting bolt 61 and valve body 1's clearance.
Further, as shown in fig. 2 to 3, the adjusting module further includes: and the third sealing ring is arranged between the adjusting bolt 61 and the valve body 1, so that the sealing performance is improved.
When the small-fire regulating valve is used, the small-fire regulating valve is communicated with an external pipeline of an original switch valve in a matching mode, when gas needs to be conveyed, the switch valve is opened, the gas is conveyed to the small-fire regulating valve, enters from the gas inlet 11 and is conveyed to the gas inlet section 31 in the second passage 3, then the small-flow gas is conveyed to the gas outlet section 32 through the flow passage 62 or the flow passage 62 and the gap between the regulating bolt 61 and the valve body 1 according to the screwing position of the preset regulating bolt 61, and finally the small-fire state is achieved by discharging the gas outlet 12. When the big fire state needs to be changed, the valve is opened by switching on the forward voltage, and the power is cut off after the valve is opened, so that the large-flow gas is conveyed through the first passage 2 and is discharged from the gas outlet 12, and the small-flow gas is also continuously conveyed at the moment, thereby realizing the big fire state. When the state of the small fire needs to be replaced again, the reverse voltage is switched on to close the valve, the power is cut off after the valve is closed, only the gas outlet section 32 discharges the gas with small flow, and the state of the small fire is realized.
Above, having described with reference to fig. 1 to 3 the small fire regulating valve according to the embodiment of the present invention, the present case is produced and manufactured at a lower cost, and the present case only needs to be power-consumptive when opening and closing the valve, does not need to be power-consumptive when maintaining the state of opening and closing the valve, can greatly save the consumption of electric energy, and the present case can realize the switching function of the large and small fire by adding the mode of this valve on the basis of the pipeline of the original switch valve through the design of two passages, and satisfy the requirement of the specific control function.
