가스절단기는 아세틸렌이나 LPG 등의 연료가스와 산소가 혼합된 혼합가스를 연소시켜서 발생되는 화염 및 연소열에 의해 금속판재를 예열시키고, 고압의 산소가스를 분사하여 금속 소재를 산화시켜서 절단하는 장치이다. 도 1은 종래의 가스절단장치의 구조를 보여주는데, 도시된 바와 같이, 별체로 구비된 산소탱크(1)와 아세틸렌이나 LPG 등의 연료탱크(2)가 산소호스(3)와 연료호스(4)를 통해 각각 가스절단기(10)의 산소관(12)과 가스관(13)으로 연결된다. 산소탱크(1)와 연료탱크(2)의 상단에는 각각 탱크압력게이지(5)와 압력조절밸브(6) 및 작업압력게이지(7)가 구비되어 산소호스(3) 및 연료호스(4)에 연결된다. 탱크압력게이지(5)를 통해 산소탱크(1)나 연료탱크(2) 내의 기체의 충전압력을 육안으로 확인하고, 압력조절밸브(6)를 통해 고압인 탱크압력을 절단기의 노즐이나 피가공물의 재질에 적합한 범위로 감압시킨다. 그리고, 작업압력게이지(7)를 사용하여 실제로 절단작업에 사용되는 산소나 연료가스의 압력치를 확인하며 조절한다. 그리고, 가스절단기(10)의 선단에는 노즐팁(11)이 구비되어, 노즐의 중앙부에서는 고압의 산소가 분사되고 노즐의 둘레부에서는 연료가스와 산소가 혼합된 혼합가스가 분사되면서 연소되어 화염과 열을 발생하게 된다.The gas cutting machine is a device that preheats the metal sheet by flame and combustion heat generated by burning a mixed gas of fuel gas such as acetylene or LPG mixed with oxygen, and oxidizes and cuts the metal material by injecting high pressure oxygen gas. Figure 1 shows the structure of a conventional gas cutting device, as shown, the oxygen tank (1) and the fuel tank (2), such as acetylene or LPG provided separately, the oxygen hose (3) and fuel hose (4) Through is connected to the oxygen pipe 12 and the gas pipe 13 of the gas cutter 10, respectively. At the upper end of the oxygen tank 1 and the fuel tank 2, a tank pressure gauge 5, a pressure regulating valve 6 and a working pressure gauge 7 are provided to the oxygen hose 3 and the fuel hose 4, respectively. Connected. The tank pressure gauge 5 visually checks the filling pressure of the gas in the oxygen tank 1 or the fuel tank 2 and checks the tank pressure, which is high pressure, through the pressure regulating valve 6. Reduce the pressure to the appropriate range for the material. Then, using the working pressure gauge (7) to check and adjust the pressure value of the oxygen or fuel gas actually used in the cutting operation. And, the tip of the gas cutter 10 is provided with a nozzle tip 11, the high pressure oxygen is injected at the center portion of the nozzle and the mixed gas of fuel gas and oxygen is injected at the circumference of the nozzle is burned and flame and It generates heat.

그런데, 종래의 이러한 가스절단장치는, 절단기용 연료로서 LPG나 아세틸렌 등의 가스만을 사용하도록 되어 있고, 액체연료를 사용하면 연료탱크로부터 액체연료의 토출에 필요한 소요의 가압수단이 없기 때문에 부피 대비 에너지효율이 우수하고 상대적으로 입수가 용이한 액체연료를 사용할 수 없다는 문제점이 있었다.However, the conventional gas cutting device uses only gas such as LPG or acetylene as the fuel for cutting, and when the liquid fuel is used, there is no necessary pressurizing means necessary for discharging the liquid fuel from the fuel tank. There is a problem that can not use the liquid fuel with excellent efficiency and relatively easy to obtain.

본 발명은 전술한 바와 같은 종래의 가스절단기의 문제점에 착안하여 제안된 것으로서, 본 발명은 액체연료는 물론, 부피 대비 에너지 효율이 우수하게 상대적으로 입수가 용이한 액체연료를 사용할 수 있는 새로운 구조의 절단기를 제공하고자 하는 것이다. The present invention has been proposed in view of the problems of the conventional gas cutting machine as described above, and the present invention provides a liquid structure, as well as a novel structure that can use liquid fuel, which is relatively easy to obtain with excellent energy efficiency to volume. It is to provide a cutter.

According to the present invention, an oxygen tube 12 to which the oxygen hose 3 is connected and a fuel tube 13 to which the fuel hose 4 is connected to the rear end of the cutter body 10 are extended to form the cutter body 10. At the front end of the), the high-pressure oxygen tube 14 and the low-pressure oxygen tube 15 and the fuel pipe 13 or the mixed gas pipe flowing by mixing the low-pressure oxygen and fuel, respectively branched from the oxygen tube 12 is extended, In the gas cutting machine in which the nozzle tip 11 is connected to the tip portion thereof, a bypass pipe 8 is connected between the oxygen pipe 12 and the fuel pipe 13, and the bypass pipe 8 is opened and closed. A cutter is provided, characterized in that (9) is provided, and a check valve (17) is provided that opens only from the oxygen pipe (12) toward the fuel pipe (13).

이하에서 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다. 도 2는 본 발명의 실시예의 구조도이다. 도시된 바와 같이, 본 발명에 따르면, 절단기 본체(10)의 후단으로 산소호스(3)가 연결되는 산소관(12)과, 연료호스(4)가 연결되는 연료관(13)이 연장형성된다. 그리고, 절단기 본체(10)의 전방으로는 상기 산소관(12)이 분기된 고압산소관(14)과 저압산소관(15)이 연장되고, 그 하부에는 상기 연료관(13)이 그대로 연장된다. 그러나, 저압산소관(15)과 연료관(13)이 별도로 구비되는 대신 저압산소관(15)과 연료관(13)이 하나의 혼합가스관으로 합쳐져서 절단기 본체(10) 내부에서 저압산소와 연료가 혼합되어 이 혼합가스관을 통해 흐를 수도 있을 것이다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. 2 is a structural diagram of an embodiment of the present invention. As shown, according to the present invention, the oxygen tube 12 to which the oxygen hose 3 is connected to the rear end of the cutter body 10 and the fuel tube 13 to which the fuel hose 4 is connected are extended. . The high pressure oxygen tube 14 and the low pressure oxygen tube 15 branched from the oxygen tube 12 extend in front of the cutter body 10, and the fuel tube 13 extends in the lower portion thereof. . However, the low pressure oxygen pipe 15 and the fuel pipe 13 are not provided separately, but the low pressure oxygen pipe 15 and the fuel pipe 13 are combined into one mixed gas pipe so that the low pressure oxygen and the fuel are reduced inside the cutter body 10. It may be mixed and flow through this mixed gas pipe.

또한, 이들 관(13,14,15)의 선단부에는 노즐팁(11)이 접속되고, 이들 관(13,14,15) 상에는 상기 절단기 본체(10)에 구비되는 유량조절밸브(21,22,23)가 각각 접속된다. 산소관(12)의 유량조절밸브(21) 전단에는 압력조절밸브(6)가 접속된다. 그리고, 절단기 본체(10)의 후방에는 손잡이(19)가 연장 형성된다.In addition, a nozzle tip 11 is connected to the distal end of the pipes 13, 14, and 15, and on the pipes 13, 14, and 15, the flow control valves 21, 22, 23) are respectively connected. The pressure regulating valve 6 is connected to the front end of the flow regulating valve 21 of the oxygen pipe 12. And, the handle 19 is formed to extend behind the cutter body (10).

그리고, 본 발명에 따르면, 산소관(12)과 연료관(13) 사이에는 바이패스관(8)이 접속된다. 바이패스관(8)의 바람직한 위치는 유량조절밸브(2122,23)의 전단이다. 이 바이패스관(8)에는 개폐수단(9), 바람직하게는 개폐버튼이 구비되어 이 바이패스관(8)을 작업자가 필요시에 임의적으로 개폐조작할 수 있다. 그리고, 이 개폐수단(9)의 일측, 즉, 연료관(13)쪽에는 체크밸브(17)가 구비되어, 산소관(12)으로부터의 고압 산소가 연료관(13) 쪽으로 유입될 수 있으나, 연료관(13)으로부터산소관(12)으로 연료가 역류하는 것을 방지한다. 이러한 구성은 종래의 가스절단기와 달리, 연료로서 휘발유나 벤젠 등의 액체연료를 사용하는 경우에,고압의 산소를 산소관(12)으로부터 바이패스관(8)을 통해 연료탱크(2)로 주입시켜서 연료탱크(2)에 담긴 액체연료를 가압시킴으로써, 절단작업시에 가압된 액체상태의 연료를 이 연료관(13)을 통해 용이하게 분출시킬 수 있도록 할 수 있다. 따라서, 노즐팁(11)의 구조를 액체연료의 무화가 용이하도록 구조변경하고, 연료탱크(2)의 폭발을 방지하는 구조만 강구된다면 절단기에서 액체연료의 사용이 강구된다.According to the present invention, the bypass pipe 8 is connected between the oxygen pipe 12 and the fuel pipe 13. The preferred position of the bypass pipe 8 is the front end of the flow regulating valves 2122 and 23. The bypass tube 8 is provided with an opening / closing means 9, preferably an opening / closing button, so that the bypass tube 8 can be opened and closed by the operator if necessary. And, one side of the opening and closing means 9, that is, the fuel pipe 13 side is provided with a check valve 17, the high-pressure oxygen from the oxygen pipe 12 may be introduced into the fuel pipe 13, The fuel flow back from the fuel pipe 13 to the oxygen pipe 12 is prevented. This configuration is different from the conventional gas cutting machine, in the case of using liquid fuel such as gasoline or benzene as fuel, high-pressure oxygen is injected from the oxygen tube 12 into the fuel tank 2 through the bypass tube 8. By pressurizing the liquid fuel contained in the fuel tank 2, it is possible to easily eject the pressurized liquid fuel through the fuel pipe 13 during the cutting operation. Therefore, if the structure of the nozzle tip 11 is changed to facilitate the atomization of the liquid fuel, and only the structure for preventing the explosion of the fuel tank 2 is used, the use of the liquid fuel in the cutter is taken.

이상에서 설명한 본 발명에 따르면, 산소관(12)과 연료관(13) 사이에 바이패스관(8)을 연결하고, 여기에 개폐수단(9)과 체크밸브(17)을 접속함으로써, 액체연료를 사용하는 경우에는 개폐수단(9)을 개방하여 고압의 산소를 산소관(12)으로부터 연료관(13)을 통해 연료탱크(2)를 가압시킴으로써, 액체상태의 연료를 고압으로 가압시킬 수 있게 되어, 나중에 절단작업시에 가압된 액체상태의 연료가 연료관(13)을 통해 용이하게 분출됨으로써, 액체연료를 사용할 수 있다. According to the present invention described above, the liquid fuel is connected by connecting the bypass pipe 8 between the oxygen pipe 12 and the fuel pipe 13 and connecting the opening / closing means 9 and the check valve 17 thereto. In the case of using, the opening / closing means 9 is opened to pressurize the fuel tank 2 from the oxygen tube 12 through the fuel tube 13 through the high pressure oxygen, so that the fuel in the liquid state can be pressurized to a high pressure. The liquid fuel pressurized during the later cutting operation is easily ejected through the fuel pipe 13, so that the liquid fuel can be used.
