Abstract
The utility model discloses a high-pressure gas alternative supply valve, which is characterized in that the alternative supply valve comprises a valve body; a gas discharge connector is arranged on the valve body; valve covers respectively provided with gas storage rooms are arranged at two sides of the valve body; left and right punch spindles arranged in the valve body; gas guide grooves are arranged on the left and the right punch spindles which match with the valve covers; electromagnetic coils are arranged on the valve covers; and gas inlets holes are arranged on the valve covers. The left punch spindle and the right punch spindle are connected through a connecting rod, and guide rods matching with the gas inlet holes on the valve covers are arranged on the punch spindles. The axis of the punch spindles coincides with the axis of the gas inlet holes so as to be good for the smooth operation of the punch spindles. By adopting the above structure, the high-pressure gas alternative supply valve has the advantages of improving welding quality, improving production efficiency, reducing welding cost, minimizing pore incidence rate and reducing welding mist.
Description
Technical field
The utility model relates to the electric welding machine apparatus field, specifically a kind of pressurized gas alternative supply valve.
Background technique
As everyone knows, in fields such as machine building industry, shipbuilding industry, aerospace industry, automotive industrys, with inert protective gas weldment is welded, utilize electric welding machine sustainedly and stably workpiece to be welded in the mode of static pressure, the welding speed equilibrium of air pressure, in the melting type welding process, be easy to occur following point: 1, weld strength and plasticity are low, pore incidence rate height; 2, weldering mist incidence rate height; 3, during the thicker slotware of welding, need to increase welding times, the crack of crystallization often occurs, for weldering again need be carried out machine treatment at vertical soldering opening; When 4, large-scale weldment vertically being welded, bulge and not exclusively molten phenomenon take place in regular meeting, need not molten part and molten partly handle, lose time, and 5, if reduce the pore incidence rate, need the use amount of increase gas, increased the welding expense.In non-melting type welding process, have the following disadvantages: 1, a little less than the fusion power of electric arc; 2, poor because of the flowability of liquid metal in the molten bath, postpone the diffusion and the crystallization of the fusion composition at peripheral position; 3, the heterogeneity between the composition of deterioration weldment and alloy boundary strip; 4, when welding aluminum alloy, manganese, scandium, lithium are with non-melting type gas shielded arc welding the time, and the phenomenon that the composition that takes place easily to swim is vaporized can not be carried out stable welding, reduces welding quality, and the weldering mist of generation has polluted environment, has influenced the healthy of welder.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and a kind of pressurized gas alternative supply valve that can intermittently impact propelling, alternative supply gas that can improve welding quality, the generation of minimizing pore, reduce the weldering mist is provided.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of pressurized gas alternative supply valve, it is characterized in that being provided with valve body, valve body is provided with air outlet adapter, the valve body both sides are respectively equipped with the valve gap of band gas storage chamber, be provided with left and right sides drift spindle in the valve body, left and right sides drift spindle is provided with gas guide groove, and the drift spindle matches with valve gap, valve gap is provided with electromagnetic coil, and valve gap is provided with inlet hole.
Left and right sides drift spindle in the utility model is connected through connecting rod, and the drift spindle is provided with guide rod, and guide rod matches with inlet hole on the valve gap.
Drift spindle axis and inlet hole axis in the utility model coincide, and are beneficial to the smooth running of drift spindle.
The utility model is owing to adopt said structure; make shielding gas become dynamic pressure by static pressure; the gas that has improved in the metal solder molten bath overflows; the pore that has suppressed in the metal welding seam produces, and has the welding quality of raising, has improved manufacturing efficiency, has reduced the welding expense, reduces the pore incidence rate, has reduced advantage such as weldering mist generation.
