본 고안은 철판을 절단하는 수동가스 절단기에 관한 것으로서, 특히 고압산소를 제어하는 고압산소 제어레버를 부착하여 동일 작업 장내에서 작업 위치를 옮길때 고압 산소의 공급을 중단시켜 불필요한 소모를 줄이고, 또한 절단작업을 멈추었다가 다시 동일한 절단작업을 행하여야 할 경우 고압 산소의 분출량을 조절할 필요없이 고압 산소 제어레버를 누르면 앞에서 행하던 절단 작업의 조건과 동일한 불꽃조정이 이루어지도록한 가스 절약형 수동 가스 절단기에 관한 것이다.The present invention relates to a manual gas cutting machine for cutting a steel plate, in particular, by attaching a high pressure oxygen control lever for controlling high pressure oxygen to stop the supply of high pressure oxygen when moving the work position in the same workplace to reduce unnecessary consumption, and also cutting It is a gas-saving manual gas cutter which makes it possible to control the same flame as the conditions of the cutting operation by pressing the high-pressure oxygen control lever without having to adjust the amount of high-pressure oxygen ejection when it is necessary to stop the work and perform the same cutting operation again. .

종래에 일반적으로 사용하는 수동 가스 절단기(100)는 연료가스 보급밸브(1)와 연료가스 조절밸브(2)을 열여 연료가스(3)가 절단기손잡이(4)와 연료가스 공급파이프(5)를 통하여 토오치(6)의 화구(7)에서 분출되도록한후, 이 연료가스(3)를 점화하고, 고압산소 보급밸브(8)열어 고압산소 공급파이프(10)를 통하여 화구(7)에 이르도록 하여 고압산소(9)와 연료가스(3)의 혼합비를 절단 작업조건에 맞도록 고압산소 보급밸브(8)를 조절하여야 한다.The manual gas cutter 100 generally used in the art opens the fuel gas supply valve 1 and the fuel gas control valve 2 so that the fuel gas 3 opens the cutter handle 4 and the fuel gas supply pipe 5. After being discharged from the crater 7 of the torch 6, the fuel gas 3 is ignited, and the high-pressure oxygen supply valve 8 is opened to reach the crater 7 through the high-pressure oxygen supply pipe 10. In order to adjust the mixing ratio of the high pressure oxygen (9) and the fuel gas (3) to the cutting operation conditions, the high pressure oxygen supply valve (8) should be adjusted.

이렇게 알맞은 불꽃으로 조절하여 작업을 실시하다가 동일한 작업장에서 작업위치를 이동하여야 할 경우 절단작업을 행하던 불꽃 상태로 위치를 이동함으로써, 불필요한 고압산소를 소모하는 폐단이 발생되었으면, 이와 같은 소모를 줄이기 위하여 밸브(8)를 잠근후 이동하면 다시 동일한 절단작업을 위한 불꽃 조절시간에 의한 시간낭빌르 가져오는 폐단이 발생하고, 또한 작업자의 휴식등과 같은 장시간의 작업 중단후 다시 동일한 절단작업을 할 경우도 절단작업에 알맞은 불꽃으로 조절하는 시간이 필요하였다.If the work is to be adjusted to the appropriate flame and the work position is to be moved in the same workplace, if the closed end of unnecessary high pressure oxygen is generated by moving the position to the flame state where the cutting work was performed, the valve is used to reduce the consumption. If you move after locking (8), you will get a waste of time by the flame control time for the same cutting work again, and if you make the same cutting work again after a long time interruption such as worker's rest, It took time to adjust to the right flame for the job.

본 고안은 종래와 같은 고압산소의 불필요한 소모를 억제하고, 동일한 절단작업을 위한 불꽃 조절시간을 생략할수 있는 수동식 가스 절단기를 제공하려는 것이다.The present invention is to provide a manual gas cutter that can suppress unnecessary consumption of high-pressure oxygen as in the prior art, and can omit the flame control time for the same cutting operation.

이를 첨부 도면에 의거 상세하게 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

연료가스(3)는 연료가스 보급밸브(1)를 열면 절단기(200)의 손잡이(4)를 통과하여 연료가스 공급파이프(5)를 지나 토오치(6)의 화구(7)로 분출되며, 고압산소(9)는 고압산소 호스니플(16)로 유입되어 고압산소 보급밸브(8)를 통과하여손잡이(4) 내부를 지나는 고압산소 공급파이프(10)에 의해 스핀들 밸브(12)에 연결된 공급로(10')에 인입되고, 하측에 로크(14)를 돌설한 로크버튼(13)이 중앙에 슬라이드 운동될수 있도록 설치된 고압산소 제어레버(11)가 힌지(11')를 중심으로 상하 회전 동작될수 있도록 하여 이에 연동되는 스핀들 밸브로드(11'')를 하측에 접속시켜서 이 스핀들 밸브로드(11'')는 공급로(10'')를 관통하여 단이 스핀들 밸브(12)이 상부에 닿도록 설치되며, 공급로(10'')는 또 다른 고압산소 공급파이프(10a)에 연결시켜 이를 통과하는 고압산소(9)는 토오치(6)의 중앙을 지나 화구(7)에서 연료가스(3)와 혼합되도록 한다.When the fuel gas 3 opens the fuel gas supply valve 1, the fuel gas 3 passes through the handle 4 of the cutter 200, passes through the fuel gas supply pipe 5, and is ejected to the crater 7 of the torch 6. The high pressure oxygen (9) flows into the high pressure oxygen hose nipple (16), passes through the high pressure oxygen supply valve (8), and is connected to the spindle valve (12) by the high pressure oxygen supply pipe (10) passing through the handle (4). The high-pressure oxygen control lever 11 which is inserted into the furnace 10 'and installed so that the lock button 13 which protrudes the lock 14 on the lower side can be slid in the center is rotated up and down about the hinge 11'. By connecting the spindle valve rod 11 " to the lower side so that the spindle valve rod 11 " penetrates through the supply passage 10 " The supply passage 10 '' is connected to another high pressure oxygen supply pipe 10a so that the high pressure oxygen 9 passing therethrough is the torch 6 And allowed to mix with the fuel gas (3) from the surface units through the center (7).

또한 로크버튼(13)의 하부위치 즉 손잡이(4) 선단 상부에는 로크걸이(15)가 설치된 구조이다.In addition, a lock hook 15 is installed at a lower position of the lock button 13, that is, at the top of the handle 4.

이렇게 구성된 본 고안의 작용과 효과를 설명하면, 연료가스 보급밸브(1)와 연료가스 조절밸브(2)를 열어 연료가스(3)가 손잡이(4)와 연료가스 공급파이프(5)를 지나 토오치(6)의 화구(7)에서 분출되게 한후 점화하고, 고압산소 보급밸브(8)를 열어 고압산소(9)가 고압산소 공급파이프(10)를 통하여 공급로(10')에 인입되게 한후, 고압산소 제어레버(11)를 눌러 힌지(11')를 중심으로 회전되도록 하면 그 하부에 접속된 스핀들 밸브로드(11')가 밀리면서 스핀들 밸브(12)를 열어주어 공급로(10')와 또 다른 공급로(10'')를 연결하면 고압산소(9)는 공급로(10')(10'')를 통과하여 고압산소 공급파이프(10a)를 따라 토오치(6)의 중앙을 지나 화구(7)에서 연료가스(3)와 혼합되어 고온의 불꽃을 내로도록 한다.Referring to the operation and effects of the present invention, the fuel gas supply valve 1 and the fuel gas control valve 2 are opened to allow the fuel gas 3 to pass through the handle 4 and the fuel gas supply pipe 5. After ejected from the crater (7) of the ochi (6) and ignited, open the high pressure oxygen supply valve (8) to allow the high pressure oxygen (9) to be introduced into the supply path (10 ') through the high pressure oxygen supply pipe (10) When the high pressure oxygen control lever 11 is pressed to rotate about the hinge 11 ', the spindle valve rod 11' connected to the lower part of the cylinder is pushed and the spindle valve 12 is opened to open the supply passage 10 '. And another supply path 10 ", the high pressure oxygen 9 passes through the supply paths 10 ' and 10 " to follow the center of the torch 6 along the high pressure oxygen supply pipe 10a. Gina is mixed with the fuel gas (3) in the crater (7) to produce a high temperature flame.

이때 고압산소 공급밸브(8)를 조절하여 절단작업에 알맞은 불꽃으로 조절한다.At this time, by adjusting the high pressure oxygen supply valve (8) to adjust the flame suitable for the cutting operation.

이렇게 조절이 완료된 가스절단기(200)를 연속적으로 사용할때는 제2(b)도에서와 같이 하부로 눌려진 고압산소 제어레버(11)의 상부 중앙에 설치한 로크버튼(13)을 전방 즉, 토오치(6)쪽으로 밀면 로크버튼(13)의 하단에 돌설된 로크(14)가 손잡이(4) 선단상부에 고정설치된 로크걸이(15)에 끼워지면서 고압산소제어레버(11)가 고정되어 스핀들 밸브(12)를 지속적으로 열어주게 된다.In this case, when the gas cutter 200 of which adjustment is completed is continuously used, the lock button 13 installed at the upper center of the high pressure oxygen control lever 11 pressed downward as shown in FIG. 6, the high pressure oxygen control lever 11 is fixed while the lock 14 protruding from the lower end of the lock button 13 is fitted to the lock hook 15 fixed to the upper end of the handle 4. 12) will continue to open.

이렇게 절단작업 중간에 작업 위치를 이동할때는 고압산소(9)의 소모를 줄이기 위하여 로크버튼(13)을 후방으로 밀면 로크(14)가 로크걸이(15)에서 이탈되어 스핀들 밸브(12)의 내부에 개재된 스프링 탄성에 의해 스핀들밸브(12)가 공급로(10')(10'')를 차단함과 동시에 스핀들밸브로드(11'')를 밀어 고압산소 제어레버(11)를 원위치시킴으로서 고압산소(9)의 공급을 중단하게 된다.When the working position is moved in the middle of the cutting operation in this way, when the lock button 13 is pushed backward to reduce the consumption of the high pressure oxygen 9, the lock 14 is released from the lock hanger 15 and the inside of the spindle valve 12. The spindle valve 12 blocks the supply passages 10 'and 10 " by the intervening spring elasticity, and simultaneously pushes the spindle valve rod 11 " to return the hyperbaric oxygen control lever 11 to its high pressure oxygen. The supply of (9) is stopped.

이렇게 필요없는 고압산소(9)의 소모를 중단하였다가 작업 위치 이동을 완료한후 다시(9)동일 절단작업을 행할때는 고압산소 제어레버(11)를 눌러 스필들 밸브(12)를 열어주면 고압산소(9)와 연료가스(3)의 혼합 비율은 앞에서 절단 작업할때 이미 조절되어 있으므로 별도의 조절을 하지 않아도 동일한 작업 조건으로 절단 작업을 행할수 있으며, 또한 휴식등과 같은 장시간의 중단후 다시동일한 절단 작업을 행햐여햐 할 경우 연료가스 보급밸브(1)를 잠그고 고압산소제어레버(11)를 놓아 스핀들밸브(12)도 잠그면 불꽃을 소화할수 있고 다시 작업을 행할때는 연료가스 보급밸브(1)를 열어 점화한후 스핀들 밸브(12)를 열면 별도의 불꽃 조절없이 동일한 조건의 불꽃을 낼수 있게 된다.After stopping the consumption of high pressure oxygen (9), which is not necessary, and after completing the movement of the working position (9), when the same cutting operation is performed again, the high pressure oxygen control lever (11) is pressed to open the spill valve (12). Since the mixing ratio of oxygen (9) and fuel gas (3) is already adjusted when cutting, the cutting operation can be performed under the same working conditions without any adjustment. When performing the same cutting operation, close the fuel gas supply valve (1) and release the high pressure oxygen control lever (11) to lock the spindle valve (12) to extinguish the sparks. After opening the ignition and open the spindle valve 12, it is possible to produce the flame of the same condition without additional flame control.

이렇게 동작되는 본 고안은 작업의 일시 중단후 다시 동일한 절단 작업을 행할때 앞에서 행하던 작업조건을 만들기 위한 조절시간을 기할수 있으며, 작업 위치의이동시 발생하던 불필요한 고압 산소의 낭비를 해소할수 있는 유용한 고안인 것이다.The present invention, which is operated in this way, allows for adjustment time for creating the working conditions that were previously performed when performing the same cutting work again after the suspension of work, and is a useful design for eliminating unnecessary high-pressure oxygen waste generated during movement of the working position. will be.
