Abstract
The utility model relates to a gas spray nozzle comprising a gas inlet pipe (1), a reducing way (2) and a gas spraying pipe (4). The position on the gas spraying pipe near the reducing way is provided with a plurality of air inlet holes and the wall of the reducing way (2) is provided with a small hole (5). The small hole can provide first air compensation. Because the position of the reducing way has large flow rate of gas and large negative pressure, the absorbed air quantity is very large, which can break the balance flow state of the gas flow so as to make the gas and the air very evenly mixed. Therefore, the burning becomes more sufficient and the heating load of the burner is enlarged. The consumption of the gas is less than the increment of the fire power.
Description
The utility model relates to the structure of nozzle that equipment such as a kind of gas-cooker, gas heater are used.
Gas nozzle commonly used is a tubular object, and an end is an air inlet pipe, and the other end is an air jet pipe, and it is a undergauge that several air inlets, middle part are arranged on the jet tube wall.Because the aperture of undergauge is more much smaller than air inlet pipe and air jet pipe, combustion gas is very big at the flow velocity at undergauge place, and pressure is especially little, from the combustion gas of undergauge ejection the air of the air inlet on the air jet pipe is had a swabbing action, extraneous air is flowed into from air inlet, finish with combustion gas and mix for the first time.
The purpose of this utility model is the structure that proposes a kind of gas nozzle, has more performance.
This gas nozzle comprises air inlet pipe, undergauge and air jet pipe, and air inlet pipe, undergauge, air jet pipe are connected together successively, near the undergauge place several fresh air inlets is arranged on the air jet pipe, also has an aperture on the wall of undergauge.
This gas nozzle, owing on the wall of undergauge, have an aperture, combustion gas from undergauge fast by the time, have air in certain amount suck in the aperture as the first time air mend into because negative pressure herein is bigger, amount of air drawn is very big, and making gas-flow break the state of smooth flow, the air inlet on air jet pipe sucks air once more then, can make combustion gas and Air mixing even especially, it is more abundant to burn, and has increased the thermic load of burner.Adopt original burner, other size constancy of nozzle, only increase undergauge wall aperture after, about the height of flame can double, and the consumption of combustion gas is significantly less than the recruitment of firepower.
Accompanying drawing 1 is the structure chart of this gas nozzle;
Accompanying drawing 2 is the practical application figure of this gas nozzle;
As shown in Figure 1, the air inlet pipe of gas nozzle (1), undergauge (2) and air jet pipe (4) are connected together successively, and (3) are fresh air inlet, and (5) are the aperture on the undergauge wall.Fresh air inlet (3) can have several, for example, and six.For the number that makes fresh air inlet can change, just the secondary air amount is adjustable, fresh air inlet (3) can be made screwed hole, can load onto bolt in the part fresh air inlet it is blocked when needed like this.
A kind of form that shown in Figure 2 is when this gas nozzle is contained on the gas-cooker.The air jet pipe of nozzle is contained in the inlet of burner pneumatic duct (7), forms the 3rd air intake (6) with the porch of pneumatic duct, herein can be by the air door of adorning a hand adjustment.(8) are collection chamber among the figure, and (9) are burner port, and (10) are burner housing.
This gas nozzle can be used on the devices such as domestic gas-fired water heater, kitchen range, also can be used on the kitchen range of dining room, restaurant's use, all can play the raising thermic load, saves the effect of combustion gas.
Claims (2)
1, a kind of gas nozzle, comprise air inlet pipe (1), undergauge (2) and air jet pipe (4), air inlet pipe, undergauge, air jet pipe are connected together successively, have located several fresh air inlets (3) near undergauge (2) on the air jet pipe, it is characterized in that having an aperture (5) on the wall of described undergauge (2).
2, gas nozzle as claimed in claim 1 is characterized in that described fresh air inlet is a screwed hole.
