While welding by using argon gas or carbon dioxide, the utility model canavoid a large amount of argon gas or carbon dioxide waste effectively, and has the advantages of simple structure and easy manufacture.
Description
Technical field
The utility model relates to a kind of self closing device that is used for argon gas or carbon dioxide welding, especially for the safety shutoff on argon gas or the carbon dioxide welding machine.
Background technology
At present, when people utilize argon gas or carbon dioxide to weld, gas is connected with welding machine by tracheae through argon gas table or carbon dioxide table, normal barometric pressure in argon gas or the dioxide bottle is 12 atmospheric pressure, through being about 0.03 atmospheric pressure behind the air gauge decompress(ion), just can weld normally then.But when but not carrying out welding job after the welding machine start, the air pressure of section endotracheal residual air of this from the welding machine to the gas cylinder also is 12 atmospheric pressure.When start is welded once more, will spray one violent gas from muzzle and just can get back to 0.03 atmospheric pressure, just can carry out normal welding job then, the violent gas of this strand is the gas of waste.The staff who is engaged in stainless steel and carbon dioxide gas welding job is desultory when welding, and the number of times that opens and closes welding machine is very many.At the end of the day, will waste a large amount of gas, the tolerance that facts have proved waste is 3 times of gas consumption.
Summary of the invention
The purpose of this utility model provides a kind of energy-conservation safety shutoff, is used for argon gas or carbon dioxide welding machine, wastes a large amount of argon gas or carbon dioxide when preventing to weld.
For achieving the above object, the technical solution of the utility model is: a kind of energy-conservation safety shutoff comprises at least one pressure-reducing valve, pressure-reducing valve comprises valve body, valve gap, inlet suction port and air outlet adapter, valve body has step, valve gap compresses barrier film, be connected with pull bar on the barrier film, steam vent is arranged on the valve gap, inlet suction port is connected with piston seat, have air admission hole, air inlet and piston hole on the piston seat, be provided with piston in the piston hole, piston is connected with driving lever, driving lever is connected with pull bar, is connected with return spring on the driving lever.
Have seal groove on the described step, the projection on the barrier film places in the seal groove.
Described piston face has sealing ring, and there is seal gasket the end, and there is boss shape valve the inlet suction port end.
Described inlet suction port is connected with argon gas table or carbon dioxide table.
The beneficial effects of the utility model: should be connected with the argon gas table by inlet suction port by energy-conservation safety shutoff, when welding with argon gas or carbon dioxide, the pressure of gas is 0.03 atmospheric pressure in the energy-conservation safety shutoff, when welding machine quits work the welding machine switch closure, the pressure rises of energy-conservation safety shutoff, when air pressure was 0.04 atmospheric pressure, the barrier film in the energy-conservation safety shutoff moved up, thereby the drive piston is closed the gas outlet of argon gas table.At this moment, the air pressure from energy-conservation safety shutoff to the endotracheal residual air of this section of welding machine is 0.04 atmospheric pressure.When opening welding machine once more and weld, can get back to 0.03 atmospheric pressure again, at this moment just can be more suddenly gas blowout go out, thereby can save a large amount of gases.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of pressure-reducing valve.
Among the figure: 1-valve body 2-valve gap 3-barrier film 4-inlet suction port 5-air outlet adapter 6-piston seat 7-piston 8-pull bar 9-driving lever 10-return spring 11-air inlet 12-steam vent 13-seal groove 14-seal gasket 15-sealing ring 16-support 17-supporting plate 18-air admission hole 19-piston hole 20-boss shape valve (20).
The specific embodiment
As shown in the figure, pressure-reducing valve comprises valve body 1, valve gap 2, inlet suction port 4 and air outlet adapter 5, and valve body 1 has step, has seal groove 13 on the step, and the projection on the barrier film 3 places in the seal groove 13.Valve gap 2 compresses barrier film 3, and the center of barrier film 3 is connected with pull bar 8, and barrier film 3 tops are provided with supporting plate 17; Steam vent 12 is arranged on the valve gap 2, and an end of inlet suction port 4 is connected with piston seat 6, and its other end is connected with argon gas table or carbon dioxide table.Have air inlet 11, air admission hole 18 and piston hole 19 on the piston seat 6, be provided with piston 7 in the piston hole 19, driving lever 9 is hinged with piston seat 6, and piston 7 is stirred in the end of driving lever 9, the other end of driving lever 9 is connected with pull bar 8, is provided with return spring 10 between driving lever 9 and the valve body 1.There is sealing ring 15 on piston 7 surfaces, and there is seal gasket 14 piston 7 ends, and there is boss shape valve 20 inlet suction port 4 ends.Air outlet adapter 5 is connected with welding machine by pipeline.Piston seat 6 usefulness supports 16 support.Can certainly directly this energy-conservation safety shutoff be connected with gas cylinder, perhaps two such pressure-reducing valve serial connection backs be constituted an energy-conservation safety shutoff, be connected with gas cylinder then, can carry out twice step-down like this, can play the effect of saving gas equally; Three such pressure-reducing valve serial connection backs can also be constituted an energy-conservation safety shutoff, be connected with gas cylinder then, can carry out three step-downs like this.
This energy-conservation safety shutoff is connected with the argon gas table by inlet suction port 4, when carrying out welding job, under the effect of return spring 10, driving lever 9 is stirred piston 7 and is moved to the left, seal gasket 14 on the piston 7 just can not blocked air admission hole 18, gas enters in the valve body 1 through air admission hole 18 and air inlet 11, can realize air feed; When stopping to weld, welding machine cuts out, and the gas pressure in the valve body 1 raises, and this moment, barrier film 3 moved up, and by pull bar 8 and driving lever 9, moves right thereby drive piston 7, and the seal gasket 14 on the piston 7 will be blocked air admission hole 18, cuts off air feed.When barrier film 3 moved up, the air in the valve gap 2 was discharged from steam vent 12.
