본 고안은 가스기기의 가스분사노즐에 관한 것으로, 특히 가스기기에서 사용되는 공급압이 상이한 액화석유가스(LPG) 및 액화천연가스(LNG)에 공용으로 사용할 수 있는 LPG·LNG 공용 가스분사노즐에 관한 것이다.The present invention relates to a gas injection nozzle of a gas appliance, and in particular, to a LPG / LNG common gas injection nozzle that can be commonly used for liquefied petroleum gas (LPG) and liquefied natural gas (LNG). It is about.
일반적으로, 가스기기에서 사용되는 가스분사노즐은 노즐의 단부에 형성되어 있는 가스분출구를 통해 일정한 압력을 갖는 가스를 버너로 분출하며, 이때 발생된 압력으로 1차공기를 흡입하며 가스와 혼합시킨다. 따라서, 가스분사노즐은 일정량의 가스를 버너로 공급하는 동시에 1차공기를 흡입할 수 있는 구동력을 제공한다.In general, a gas injection nozzle used in a gas machine ejects a gas having a constant pressure to a burner through a gas outlet formed at an end of a nozzle, and inhales primary air at the generated pressure and mixes the gas with the gas. Accordingly, the gas injection nozzle provides a driving force capable of supplying a predetermined amount of gas to the burner and at the same time sucking primary air.
상기와 같은 가스분사노즐의 기능은 가스기기의 성능을 결정하는 중요한 요인으로 작용하는데, 가스분출구의 크기가 부적절한 경우에는 가스기기가 제기능을 발휘하지 못하거나 불완전한연소를 일으킬 수 있다.The function of the gas injection nozzle as described above acts as an important factor in determining the performance of the gas equipment. If the size of the gas outlet is inappropriate, the gas equipment may not function properly or may cause incomplete combustion.
또한, 가스분사노즐의 형상이 부적절한 경우에는 1차공기의 흡입이 영향을 받아 불완전연소 및 역화의 원인으로 작용한다.In addition, if the shape of the gas injection nozzle is inappropriate, the suction of the primary air is affected and acts as a cause of incomplete combustion and backfire.
따라서, 현재 가스기기의 연료로 사용되는 공급압이 280±50mmH2O인 LPG와 공급압이 200±mmH2O인 LNG를 버너로 공급하는 가스분사노즐의 가스분출구의 직경도 상이하여야 한다.Therefore, LPG with the supply pressure of 280 ± 50mmH 2 O and 200 ± The diameters of the gas outlets of the gas injection nozzles supplying LNG of mmH 2 O to the burners shall also be different.
제3도는 상기와 같은 이유로 인하여 종래의 가스기기에서 사용되는 LPG 및 LNG용 가스분사노즐을 나타낸 도면이다.3 is a view showing the gas injection nozzle for LPG and LNG used in the conventional gas equipment for the same reason as described above.
도면에 도시된 바와같이, 가스분출구(5,8)의 직경이 상이한 LNG용 가스분사노즐(3)과 LPG용 가스분사노즐(6)이 별개로 형성되어 있고, 가스공급관(1)과 결합되는 가스분사노즐(3,6)의 가스유입구의 외측면 단부에 나사부(4,7)가 각각 형성되어 있으며, 가스공급관(1)의 내측면 단부에도 상기 가스분사노즐(3,6)에 형성된 나사부(4,7)에 대응하는 나사부(2)가 형성되어 있다.As shown in the figure, a gas injection nozzle 3 for LNG and a gas injection nozzle 6 for LPG having different diameters of the gas outlets 5 and 8 are formed separately, and are coupled to the gas supply pipe 1. Screw parts 4 and 7 are formed at the outer end of the gas inlet 3 and 6 of the gas injection nozzles 3 and 6, and the screw parts formed at the gas injection nozzles 3 and 6 are also formed at the inner end of the gas supply pipe 1. The screw part 2 corresponding to (4, 7) is formed.
따라서, 가스기기에 사용되는 가스가 LNG인 경우에는 LNG용 가스분사노즐(3)을 가스공급관(1)에 체결하면 되고, 가스기기에서 사용되는 가스가 LPG인 경우에는 가스공급관(1)에 체결되어 있는 LNG용 가스분사노즐(3)을 제거하고 LPG용 가스분사노즐(6)을 가스공급관(1)에 체결하면 된다.Therefore, when the gas used in the gas equipment is LNG, the gas injection nozzle 3 for LNG may be fastened to the gas supply pipe 1, and when the gas used in the gas equipment is LPG, the gas supply pipe 1 is fastened. The gas injection nozzle 3 for LNG removed may be removed and the LPG gas injection nozzle 6 may be fastened to the gas supply pipe 1.
그러나, 종래에는 가스분사노즐을 교체하는 경우에 상기와 같이 기장착되어 있는 가스분사노즐을 가스공급관으로부터 제거하고 새로운 가스분사노즐을 가스공급관에 체결하여야 함에 따라 가스공급노즐 교체시 2단계의 동작이 요구된다. 따라서, 가스분사노즐 교체작업이 불편하고, 또한 교체작업시간이 오래 걸린다는 문제점이 있었다.However, in the case of replacing the gas injection nozzle, the operation of the two-stage operation when replacing the gas supply nozzle has to be performed by removing the gas injection nozzle previously mounted from the gas supply pipe and fastening a new gas injection nozzle to the gas supply pipe. Required. Therefore, there is a problem that the replacement operation of the gas injection nozzle is inconvenient, and the replacement operation takes a long time.
이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 가스분사노즐 교체시 1단계의 동작만으로 가스분사노즐의 교체가 가능하여 가스분사노즐 교체작업이 용이할 뿐만 아니라 작업시간을 단축시킬 수 있는 가스기기의 LPG·LNG 공용 가스분사노즐을 제공하는 것을 그 목적으로 한다.Therefore, the present invention has been devised to solve the above problems, and it is possible to replace the gas injection nozzles with only one step of operation when replacing the gas injection nozzles. It is an object of the present invention to provide an LPG / LNG common gas injection nozzle for an existing gas machine.
상기와 같은 목적을 달성하기 위하여 본 고안은, 가스공급관의 내측면 단부에 형성된 제1나사부와 체결되는 제2나사부가 가스유입구의 외측면 단부에 형성되어 있는 LNG용 제1가스분사노즐과, 상기 제1가스분사노즐의 가스분출구의 외측면 단부에 형성되어 있는 제3나사부에 체결되는 제4나사부가 가스유입구의 내측면 단부에 형성되어 있는 LPG용 제2가스분사노즐을 구비하는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a first gas injection nozzle for LNG, wherein a second screw portion coupled to a first screw portion formed at an inner surface end of the gas supply pipe is formed at an outer surface end of the gas inlet; And a second gas injection nozzle for LPG, in which a fourth screw portion engaged with the third screw portion formed at the outer surface end of the gas injection port of the first gas injection nozzle is formed at the inner surface end of the gas inlet. .
이하, 본 고안의 바람직한 일실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention will be described in detail.

The fourth screw part 32 is formed also in the edge part.
따라서, 가스기기에서 사용되는 연료가 LNG인 경우에는, 제2(a)도에 도시된 바와같이, 가스고급구(10)의 내측면 단부에 형성된 제1나사부(11)에 LNG용 제1가스분사노즐(20)의 가스유입구의 외측면 단부에 형성되어 있는 제2나사부(21)를 체결하면 된다.Therefore, when the fuel used in the gas machine is LNG, as shown in FIG. 2 (a), the first gas for LNG is provided in the first screw portion 11 formed at the inner end of the gas advanced port 10. What is necessary is just to fasten the 2nd screw part 21 formed in the outer surface edge part of the gas inlet of the injection nozzle 20. As shown in FIG.
또한, 가스기기에서 사용되는 연료가 LPG인 경우에는, 제2(b)도에 도시된 바와 같이, 가스공급구(10)에 LNG용 제1가스분사노즐(20)이 체결된 상태에서 가스분출구(23)가 형성되어 있는 상기 제1가스분사노즐의 외측면 단부에 형성되어 있는 제3나사부(22)에 LPG용 제2가스분사노즐(30)의 내측면 단부에 형성되어 있는 제4나사부(32)를 체결하면 된다.In addition, in the case where the fuel used in the gas equipment is LPG, as shown in FIG. 2 (b), the gas ejection port is connected with the first gas injection nozzle 20 for LNG to the gas supply port 10. The fourth screw portion formed at the inner surface end of the second gas spray nozzle 30 for LPG at the third screw portion 22 formed at the outer surface end of the first gas injection nozzle having the 23 formed therein ( 32).
상기와 같이 본 고안은, 가스분사노즐 교체시 LPG용 가스분사노즐을 LNG용 가스분사노즐에 체결하거나 LNG용 가스분사노즐에 체결되어 있는 LPG용 가스분사노즐을 제거하는 1단계의 동작만으로 가스분사노즐의 교체가 가능하므로, 가스분사노즐의 교체작업이 용이할 뿐만 아니라 교체작업시간을 단축시킬 수 있다.As described above, the present invention, when replacing the gas injection nozzle, the gas injection nozzle by fastening the LPG gas injection nozzle to the LNG gas injection nozzle or removing the LPG gas injection nozzle which is fastened to the LNG gas injection nozzle, Since the nozzle can be replaced, the gas injection nozzle can be easily replaced and the replacement time can be shortened.
본 고안은 도면에 도시된 일실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 당해 기술분야에 통상의 지식을 지닌자라면 이로부터 다양한 변형 및 균등한 타실시예가 가능하다는 점을 이해할 것이다. 따라서, 본 고안의 진정한 기술적 보호범위는 첨부된 실용신안등록청구의 범위에 의해서만 정해져야 할 것이다.Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible.
