As shown in FIGS. 1 to 3, the mixed gas opening and closing device of the gas cutting torch of the present invention is provided with handles 10 and 10a in which a pair is assembled, and one side of the handles 10 and 10a is provided with a gas. The gas supply port 14 is supplied in parallel with the oxygen supply port 12 is supplied with oxygen is installed in parallel, and the gas and oxygen introduced through the gas supply port 14 and the oxygen supply port 12 While controlling the supply amount by the gas control valve 20 and the oxygen control valve 22 to supply the mixed gas through the gas supply pipe 24 and the oxygen supply pipe 26 provided at the front end of the handle (10) (10a) A gas cutting torch 100 that can be mixed and discharged through a tip 16 mounted at the tip of the head bracket 28 connecting the gas supply pipe 24 and the oxygen supply pipe 26 is formed.

The gas supply port 14 and the oxygen supply port 12 are connected to the check valve 30, and oxygen and gas introduced through the gas supply port 14 and the oxygen supply port 12 are check valves 30. It is controlled by the gas control valve 20 and the oxygen control valve 22 installed in the distribution body 60 disposed in a predetermined region of the gas supply pipe 24 and the oxygen supply pipe 26 connected to the.

The check valve 30 is disposed on one side of the pair of handles 10 and 10a and is opened and closed by the trigger 41. In addition, the pilot valve 80 is connected to the gas supply port 14 and the oxygen supply port 12 and connected to the gas supply port 14 and the gas supply pipe 24 separately in the upper predetermined region to open and close. have.

The trigger 40 is in close contact with the control plate 34 supported by the spring 32 at the lower portion of the check valve 30 interferes with the vertical movement and the pin shaft 42 formed on the pair of handles 10 and 10a. It is fitted to be able to flow in and the locking jaw 44 is formed on one side, it is to achieve the vertical motion by the bolt (70).

One side of the chuck 70 corresponds to the engaging jaw 44 of the trigger 40 and the center portion of the pair of handles 10 and 10a is rotatably coupled to the pin shaft 42a and the other side of the pair A push rod 48 is inserted through a spring 46 while being inserted into a predetermined region of the handles 10 and 10a.

A lighter container 50 is attached to any one of the gas supply pipe 24 and the oxygen supply pipe 26 to accommodate the ordinary lighter 52 in a retractable manner.

The cutting operation of the gas cutting torch mixed gas opening and closing device of the present invention having such a configuration is to hold the handle (10) (10a), press the trigger (40), and then press the push rod 48 to the spring (46) The elastically supported burl 70 is raised from the bottom to the top.

At this time, since one end of the trigger 70 supports the locking jaw 44 of the trigger 40, the trigger 40 loses the return force and stops in the pressed state, and the protrusion of one side of the trigger 40 is stopped. Is inserted and the check valve 30 is opened because the adjustment plate 34 supported by the spring 32 is lowered to the lower end of the check valve 30.

Therefore, gas and oxygen introduced through the check valve 30 are supplied with gas and oxygen through the gas supply port 14 and the oxygen supply port 12, and operate the gas control valve 20 and the oxygen control valve 22. To adjust the supply amount of gas and oxygen, and oxygen and gas introduced through the gas supply pipe 24 and the oxygen supply pipe 26 are mixed in the distribution body 60 through the tip 16 connected to the head bracket 28. As it is discharged, ignition occurs.

Since the cutting operation is made only by making a strong flame of the ignition flame, the cutting is performed while controlling the strong flame state with the oxygen control valve 22.

In this way, the mixed gas discharged to the tip 16 is ignited, and a predetermined cutting operation is performed with a strong flame.

When the gas cutting torch 100 is stopped for a while after the cutting operation is adjusted in this manner, the trigger 40 is held in the state that the gas control valve 20 and the oxygen control valve 22 are not blocked. When slightly pressed upward, the trigger (70) supported by the locking jaw 44 of the trigger 40 is released, so that the trigger 40 is lowered without any obstacle and is supported at one end of the trigger 44. As the control plate 34 returns to its original state, the check valve 30 is closed to achieve a safe state in which gas and oxygen are blocked.

Therefore, the gas cutting torch 100 in a safe state is placed on a safety stand in the workplace and stored until the next cutting operation, and during the next cutting operation, the gas control valve 20 and the oxygen control valve 22 are not touched. When only the trigger 40 is pressed, the control plate 34 is lowered and at the same time, the check valve 30 is opened, and the amount of gas and pressure discharged to the tip 16 are discharged as they were previously worked. Create and run the job.
