Abstract
The utility model discloses a spray gun head of anaerobic welding torch. This spray gun head comprises barrel, nozzle and oxygen uptake hole, is equipped with a plurality of oxygen uptake hole, its characterized in that on the barrel around the terminal round of nozzle: an auxiliary nozzle is arranged at the adjacent position of the nozzle, and a plurality of secondary oxygen inhalation holes are arranged on a circle of gun barrel surrounding the tail end of the auxiliary nozzle. The auxiliary nozzle is added to the spray gun head, so that the combustible gas is mixed with oxygen in the air and then is gathered and sprayed again, and the combustible gas is fully mixed with oxygen sucked by the secondary oxygen suction hole again, the oxygen content of the combustible gas is further increased on the premise of ensuring that the spraying force is not obviously reduced, and the temperature of a sprayed heat source is increased.
Description
Technical Field
The utility model relates to a welding equipment especially relates to the anaerobic welding torch, specifically is a spray gun head of anaerobic welding torch.
Background
The welding torch is also called a welding torch, and is a tool for welding metal by using the mixture of oxygen and acetylene as a heat source. The oxygen-free welding torch does not need a special oxygen tank, and the oxygen in natural air and combustible gas sprayed from the acetylene compression tank are mixed to form a heat source.
The oxygen-free welding torch consists of mainly combustible gas compressing tank, pressure regulating valve, guide pipe and torch head, and the combustible gas is jetted from the compressing tank via the pressure regulating valve, the guide pipe and the torch head and ignited to form jet heat source.
The spray gun head consists of a gun barrel, a nozzle and oxygen absorbing holes, wherein a circle of the gun barrel surrounding the tail end of the nozzle is provided with a plurality of oxygen absorbing holes, oxygen in air can be absorbed by the oxygen absorbing holes according to the ejection and absorption principle to be mixed with combustible gas ejected by the nozzle and then ejected out of the gun barrel, and the mixture is ignited to form an ejection-shaped heat source for metal welding.
Currently, the known oxygen-free welding torch sprays heat sources with temperatures between 1500 and 1600 degrees, which can only weld copper tubes below 19 mm. Due to the fact that the living standard is continuously improved, more and more copper pipes used for central air conditioners, floor heating systems and the like are larger than 19mm, construction difficulty is increased due to the fact that the temperature of a heat source sprayed by a welding torch is limited when the copper pipes are welded, and construction quality is reduced. Therefore, how to increase the temperature of the heat source for the oxygen-free torch jet is a problem to be solved.
SUMMERY OF THE UTILITY MODEL
The utility model discloses solve the limited problem of heat source temperature that present anaerobic welding torch sprays, will improve heat source temperature so that the welding is greater than 19 mm's copper pipe.
The utility model discloses the spray gun head of anaerobic welding torch comprises barrel, nozzle and oxygen uptake punch combination, is equipped with a plurality of oxygen uptake hole, its characterized in that on the barrel around the terminal round of nozzle: an auxiliary nozzle is arranged at the adjacent position of the nozzle, and a plurality of secondary oxygen inhalation holes are arranged on a circle of gun barrel surrounding the tail end of the auxiliary nozzle.
The utility model provides a spray gun head of this kind of anaerobic welding torch is owing to increased a secondary nozzle for gather once more after the oxygen in combustible gas and the air mixes and spray, and with the inspiratory oxygen intensive mixing once more of secondary oxygen uptake hole, further increase combustible gas's oxygen content under the prerequisite of guaranteeing not obviously to reduce the injection force, thereby improve the heat source temperature who sprays. According to flame temperature lifting principle, the oxygen content of every increase 1 degree can make flame temperature improve 80 degrees, the utility model discloses utilize twice to penetrate to inhale the principle and increased and inhaled oxygen volume and make flame temperature improve 300 to 400 degrees to the heat source temperature of injection is close 2000 degrees, has made things convenient for the welding to be greater than 19 mm's copper pipe.
Drawings
The attached drawings are the structure schematic diagram of the utility model, wherein: 1. a conduit; 2. a barrel; 3. a nozzle; 4. an oxygen inhalation hole; 5. a secondary nozzle; 6. and (5) secondary oxygen inhalation holes.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As can be seen from the attached drawing, the conduit 1 is connected with the spray gun head of the oxygen-free welding torch, and the other end can be connected with a pressure regulating valve and an acetylene compression tank. The gun head is a barrel-shaped hollow cylinder, a nozzle 3 is arranged at the connecting end of the gun head and the guide pipe 1, a plurality of oxygen absorbing holes 4 are formed in the barrel 2 which surrounds the circle at the tail end of the nozzle 3, when combustible gas in the compression tank is ejected from the nozzle 3 through the guide pipe 1, oxygen in the air is absorbed through the oxygen absorbing holes 4 by using the injection and absorption principle, then the combustible gas is gathered through the auxiliary nozzle 5 arranged at the adjacent position of the nozzle 3 and then is ejected, the combustible gas which has absorbed a certain oxygen content is ejected again and then is subjected to oxygen absorption again through the secondary oxygen absorbing holes 6 formed in the barrel 2 which surrounds the circle at the tail end of the auxiliary nozzle 5, so that the oxygen content of the combustible gas is improved, the flame temperature is increased along with the increase of the oxygen content, the temperature of an ejected heat source is close to 2000 ℃, the welding of copper pipes larger than 19 mm.
