Description

Torch {TORCH}

The present invention, even if the operator place the body in the working place in the state of being electrically connected to the oxygen line and the gas inlet coupled to the oxygen inlet and gas inlet of the body, respectively, even if the work place empty for rest, lunch, dinner, etc. To the oxygen line and the gas line of the body to prevent the supply of oxygen and gas, respectively, to a torch that can prevent large fire accidents, explosion accidents and life accidents.

In general, a gas welding device is a fuel gas distributor is supplied to the torch through a fuel gas hose receives a gas fuel from a gas fuel supply source, the oxygen gas distributor is supplied to the torch through an oxygen gas hose to receive oxygen gas from the oxygen gas source. Supplied to.

However, since the actual extension length of the fuel gas hose and the oxygen gas hose of the gas welding device is so long as to reach 100m or more, the fuel gas hose and the oxygen gas hose are damaged as well as the fuel gas and the oxygen gas due to the external force. Leakage concerns are also very high.

In addition, a coupler is provided at the ends of the fuel gas hose and the oxygen gas hose for connecting to the torch, and for ease of use, a coupler is automatically closed when the torch is separated.

When the worker finishes the welding operation, the torch is separated from the fuel gas hose and the oxygen gas hose and stored separately, and the fuel gas hose and the oxygen gas hose are left in a state filled with fuel gas and oxygen.

In this state, when a part of the fuel gas hose and the oxygen gas hose is damaged or cut, the fuel gas and the oxygen gas leak.

A part of the fuel gas hose and the oxygen gas hose is damaged or cut, and there is a problem that a human accident may occur, such as an explosion or suffocation due to a spark, a cigarette fire, etc. in a state where the fuel gas and the oxygen gas are leaked.

Recently, as shown in FIG. 1, when the torch 100 is coupled to and electrically connected to the gas welding apparatus, power of the power supply unit 200 is supplied to the first solenoid valve 80 and the second solenoid valve 90.

A separate delay circuit may be built in the body 610, but is not necessarily limited thereto, and may be provided at various locations.

More specifically, when the switch member 60 made of the magnetic reed switch is operated in the ON state,

The first and second solenoid valves (80 in FIG. 1 and 90 in FIG. 1) may be supplied to the body 10 for a predetermined time so that gas and oxygen may be supplied to the body 10 for the predetermined time in the delay circuit. And a flow path of the oxygen line 120, and after the predetermined time has elapsed in the delay circuit, the first and second solenoid valves (80 in FIG. 1 and 90 in FIG. 1) are connected to the gas line. The flow path of 110 and the flow path of the oxygen line 120 are closed.

When the switch member 60 made of the magnetic reed switch is operated in an OFF state,

The first and second solenoid valves (80 in FIG. 1 and 90 in FIG. 1) are used for the predetermined time in the delay circuit so that the gas and oxygen supplied to the body 10 can be cut off after a predetermined time. The flow path of the line 110 and the flow path of the oxygen line 120 is opened, and after a predetermined time has elapsed in the delay circuit, the first and second solenoid valves (80 in FIG. 1 and 90 in FIG. 1). Is to close the flow path of the gas line 110 and the oxygen line 120.

As a result, the oxygen line 120 and the gas line 110 of the body 10 are coupled to the oxygen line 120 and the gas line 110, respectively, so that the worker is in the peripheral position at the work place. After a certain time so that the oxygen and gas are not supplied to the oxygen line 30 and the gas line 20 of the body 10 even if the work place is empty for a temporary rest, lunch, dinner, etc. You can block.

Next, the gas inlet 20 and the oxygen inlet 30 may be formed of nipples 210 and 310, respectively.

On the other hand, when the gas inlet 20 and the oxygen inlet 30, which may be made of a conductor having a high conductivity and the nipples (210, 310) including an iron plate placed on the floor of the work place,

Power supplied to the gas inlet 20 is continuously supplied to the oxygen inlet 30 due to a large conductivity including an iron plate, and the like. The first and second solenoid valves (80 in FIG. 1 and 90 in FIG. 1) There is a fear that large fire accidents, explosion accidents and life-saving accidents may occur by continuously supplying gas and oxygen to the body 10 by continuously opening the flow paths of the gas line 110 and the oxygen line 120. With that,

In order to prevent this, the surfaces of the nipples 210 and 310 constituting the gas injection hole 20 and the oxygen injection hole 30 are preferably coated with insulation.

The present invention configured as described above is electrically switching between the oxygen inlet 30 and the gas inlet 20 of the body 10 provided with the oxygen inlet 30 and the gas inlet 20 having an insulated structure The oxygen line 120 and the gas line 110 are coupled to the oxygen inlet 30 and the gas inlet 20 of the body 10 through the switch member 60 to allow the worker to be electrically connected. Place the body (10) in the work place around the vacant place for temporary rest, lunch, dinner, etc. Even if the work place is empty and oxygen and gas to the oxygen line 120 and gas line 110 of the body 10, respectively It can be blocked so that there is an advantage that can prevent large fire accidents, explosions and life-saving accidents.
