Furthermore, the distance between the front end surface of the air outlet nozzle and the front end surface of the gun cover is 20-40 mm.
Furthermore, the clearance between the outer side surface of the air baffle ring and the inner wall of the gun cover is 3-10 mm.
Due to the adoption of the structure, the utility model discloses following beneficial effect has:
1. the utility model improves the structure of the welding gun, the gas is sprayed out from the front end of the gun cover to be burnt, and the inner diameter of the gun cover is far larger than the diameter of the gun core nozzle, so the gas is not easy to be blocked by the substances generated by burning; and the position of gas burning is far away from the gas outlet nozzle of the welding gun, the gas outlet nozzle of the gun core cannot be blocked by substances generated by burning, and the welding gun is not easy to damage. The service life of the improved welding gun is at least more than 2 months. The extension of welder life can reduce the work load that the workman changed welder on the one hand, and the production time of having practiced thrift simultaneously has improved production efficiency, and on the other hand has also reduced the expenditure of equipment cost, has reduced manufacturing cost.
2. The utility model discloses 3-4 ventholes have been opened to welder's branch on the outer circumference of gas-out round bar equipartition, in addition the air outlet nozzle, and 4-5 department positions are given vent to anger altogether, and the gas that comes through a plurality of ventholes of branch gas-out round bar branch flows out blocks the direction back through keeping off the gas ring, and gas is to keeping off the peripheral diffusion of gas ring, and the dispersion of giving vent to anger is even, more does benefit to the abundant burning of natural gas.
The technical features of a gas brazing welding torch according to the present invention will be further described with reference to the accompanying drawings and examples.
