Abstract
The utility model relates to a fuel gas welding nozzle which comprises a spraying nozzle. The spraying nozzle is provided with a channel, the air inlet end of the spraying nozzle is connected with a welding torch, a combustion head is arranged at the air inlet end of the spraying nozzle, and a flow guiding chamber is arranged on the combustion head and is communicated with the gas in the channel, combustion holes are arranged on the combustion head and communicated with the gas in the flow guiding chamber, and the mixed fuel gas delivered from the welding torch is portioned after being further fully mixed in the flow guiding chamber, a great amount of gas directly enters into a main combustion hole and a small amount of gas enters into an auxiliary combustion hole. After the mixed fuel gas is ignited, because the main combustion hole and the channel are coaxial, the airflow velocity is high, the flow capacity is large, the diameter of the flame is thick and long, and the fire is main heating flame and a main body for welding and heating; while smaller airflow, lower flow velocity and small flame can be obtained through the radially distributed auxiliary combustion hole, and the fire is auxiliary heating flame used for assisting the main flame to heat, so that the high welding temperature can be further increased, and when the possibility that the main flame extinguishes happens, the main flame is ignited so that the flame cannot extinguish.
Description
Technical field
The utility model relates to a kind of gas welding torch, specifically, relates to a kind of Gas welding nozzle.
Background technology
At present, using gas welding torch at mechanical field, to carry out metal solder be welding manner very widely, the structure of common gas welding torch generally comprises the welding torch that combustion gas and oxygen are mixed, and tip with a burner port, the tip of this gas welding torch is owing to have only a burner port, therefore existence is easily flame-out, flame diameter is thin, the shortcoming that the efficiency of heating surface is slow.
Summary of the invention
Technical problem to be solved in the utility model is at above defective, provides a kind of flame diameter thick, fast, the difficult flame-out Gas welding nozzle of the efficiency of heating surface.
For addressing the above problem, the utility model adopts following technical scheme: Gas welding nozzle, comprise nozzle, described nozzle has passage, and the inlet end of described nozzle is connected with welding torch, it is characterized in that: the gas outlet end of described nozzle is provided with combustion head, described combustion head is provided with a diversion chamber, described diversion chamber is communicated with passage gas, and described combustion head is provided with burner port, and described burner port is communicated with diversion chamber gas.
Below be further improvement in the technical proposal:
Described burner port comprises a main burner port and several secondary burner ports, described main burner port and passage concentric.
Described combustion head is provided with an annular construction member, and the gas outlet end of described annular construction member and nozzle is tightly connected, and the gas outlet end of described nozzle, combustion head, annular construction member constitute diversion chamber.
The gas outlet end of described nozzle is provided with boss, and this boss has the through hole with channel connection, and the gas outlet of boss is apart from 3～5 millimeters of the air inlet end faces of combustion head.
The gas outlet end of described main burner port is provided with boss, and described boss has the through hole that is communicated with main burner port.
Beneficial effect
The utility model adopts technique scheme, have the following advantages: the setting of main burner port, secondary burner port and diversion chamber on the combustion head, can make the air mixture that transports from welding torch, further fully mixing the back in diversion chamber distributes, most of gas directly enters main burner port, and small part gas enters secondary burner port.After lighting, because main burner port is coaxial with passage, air-flow velocity height, flow are big, and flame diameter is slightly grown, and is main heating flame, is the main body of weld heating; Radially-arranged secondary burner port obtains less air-flow, less flow velocity, and flame is little, for attached helping adds thermal-flame, assists main flame heating, further improves welding temperature, and when there was flame-out possibility in main flame, the main flame that ignites guaranteed flame-out.
Below in conjunction with drawings and Examples the utility model is further described:
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 be among Fig. 1 A to structural representation.
The specific embodiment
The 1-nozzle, 2-passage, 3-combustion head, 4-master's burner port, the secondary burner port of 5-, 6-diversion chamber, 7-annular boss, 8-annular boss, 9-annular construction member
Embodiment, as shown in Figure 1, Gas welding nozzle, comprise nozzle 1, nozzle 1 has passage 2, the inlet end of nozzle 1 is connected with welding torch, the gas outlet end of nozzle 1 is provided with combustion head 3, combustion head 3 is provided with an annular construction member 9, and annular construction member 9 is tightly connected the gas outlet end of nozzle 1 with the gas outlet end of nozzle 1, combustion head 3, annular construction member 9 constitutes diversion chamber 6, diversion chamber 6 is communicated with passage 2 gas, main burner port 4 and passage 2 concentrics, main burner port 4 and secondary burner port 5 are communicated with diversion chamber 6 gas, and the gas outlet end of nozzle 1 is provided with boss 8, this boss 8 has the through hole that is communicated with passage 2, the gas outlet of boss 8 is apart from 4 millimeters of the air inlet end faces of combustion head 3, and the gas outlet end of main burner port 4 is provided with boss 7, and boss 7 has the through hole that is communicated with main burner port 4.
As shown in Figure 2, combustion head 3 is provided with a main burner port 4 and 8 radially equally distributed secondary burner ports 5, and the aperture of secondary burner port 5 is littler than the aperture of main burner port 4.
During use, nozzle, combustion head are connected on the welding torch, the air mixture from welding torch transports mixes in diversion chamber, distributes, and most of gas directly enters main burner port, and small part gas enters secondary burner port.After lighting, because main burner port is coaxial with passage, air-flow velocity height, flow are big, and flame diameter is slightly grown, it is main heating flame, be the main provider of weld heating thermal source, radially-arranged secondary burner port obtains less air-flow, less flow velocity, flame is little, for attached helping adds thermal-flame, assist main flame heating, further improve welding temperature; And when there was flame-out possibility in main flame, the main flame that ignites guaranteed flame-out.
