Description
본 고안은 가스 배출 장치에 관한 것으로 특히 LPG 차량에 있어서 프로판 가스가 누출될 경우 압력센서를 이용하여 이를 감지하고 강제로 배출함으로써 차량 안에 프로판 가스가 축적되어 일어날 수 있는 사고를 미연에 방지하기 위한 압력센서를 이용한 LPG 누출가스 배출장치에 관한 것이다.The present invention relates to a gas discharge device. In particular, when a propane gas leaks in an LPG vehicle, a pressure sensor is used to detect and forcibly discharge the pressure to prevent an accident that may occur due to accumulation of propane gas in the vehicle. The present invention relates to an LPG leak gas discharge device using a sensor.
LPG는 액화석유가스(Liquified Petroleum Gas)를 말하여 가솔린 기관과는 연료장치가 다르고, 가솔린의 연료비의 부담 증가로 보다 경제적인 연료로서 보급되었다. LPG는 일산화탄소 함유량이 적어 대기오염을 방지하며 옥탄가가 높기 때문에 노킹을 방지할 수 있는 이점도 있다.LPG refers to Liquified Petroleum Gas, which has a different fuel system than gasoline engines, and has been supplied as a more economical fuel due to an increase in the fuel cost of gasoline. LPG has a low carbon monoxide content to prevent air pollution and has a high octane number to prevent knocking.
LPG로는 프로판, 부탄, 프로필렌, 부틸렌 등이 사용되며 LPG 연료장치는 연료 탱크, 여과기, 솔레노이드 밸브, 증발기, 기화기 등으로 구성된다.LPG includes propane, butane, propylene, butylene, etc. LPG fuel system is composed of a fuel tank, a filter, a solenoid valve, an evaporator, a vaporizer, and the like.
이 중 솔레노이드 밸브는 기관 키 스위치에 의해 작동하며 연료 통로를 개폐하고, 증발기는 LPG를 감압 기화시켜 일정한 압력으로 유지시키고 엔진 부하의 증감에 따라 기화량을 조절함으로써 액체연료를 강제적으로 증발시켜 기관에 필요한 기체 연료를 공급시키며, 기화기는 증발기로부터 보내어진 기체상의 연료와 공기를 혼합하는 장치이다.Among them, solenoid valve is operated by engine key switch, opening and closing fuel passage, evaporator forcibly evaporating liquid fuel by forcibly evaporating liquid fuel by controlling vaporization according to increase or decrease of engine load. Supplying the necessary gaseous fuel, the vaporizer is a device for mixing air with gaseous fuel sent from the evaporator.
그런데 이러한 LPG 연료를 쓰는 경우는 기체연료를 사용하는 것이므로 잘못하여 기체가 누출될 염려가 있고 이들 연료들은 쉽게 불이 붙으므로 잘못하면 화재의 염려가 있다. 그러나 기존의 차량에는 이들 가스가 누출시 발생하는 사고를 미연에 방지할 수단이 없었다.However, when using such LPG fuel, gas fuel is used, and there is a risk of accidental gas leakage, and these fuels easily catch fire, and thus, there is a risk of fire. However, existing vehicles had no means of preventing accidents when these gases leaked out.
이에 본 고안은 상기한 문제점을 해결하기 위해 마련된 것으로 LPG 연료 장치에 있어서 기체연료의 누출시 이를 미리 감지하여 사전에 외부로 배출함으로써 사고를 미연에 방지할 수 있도록 하는 수단을 제공하는 것을 목적으로 한다.Accordingly, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a means for preventing an accident in advance by detecting a gas fuel leak in advance and discharging it to the outside in advance. .
상기한 목적을 달성하기 위하여 본 고안은 LPG 차량의 연료 탱크에서 엔진측으로 연결되는 가스 유로에 설치되어 LPG 가스의 압력을 감지하는 압력센서와, 상기 압력센서의 신호를 전달하는 제어 스위치와, 상기 제어 스위치의 신호에 따라 작동되는 배기팬을 포함하여 구성된 것임을 특징으로 하는 LPG 가스 누출시 가스 배출장치를 제공하고 있다.In order to achieve the above object, the present invention is installed in the gas flow path connected to the engine side of the fuel tank of the LPG vehicle, a pressure sensor for detecting the pressure of the LPG gas, a control switch for transmitting a signal of the pressure sensor, and the control It provides a gas discharge device in the case of LPG gas leakage, characterized in that it comprises an exhaust fan operated in accordance with the signal of the switch.

이하 첨부된 도면에 도시된 실시예를 참고로 하여 본 고안에 의한 압력센서를 이용한 LPG 누출가스 배출장치에 대해 설명하도록 한다.Hereinafter, an LPG leak gas discharge device using a pressure sensor according to the present invention will be described with reference to the embodiment shown in the accompanying drawings.
LPG 차량의 연료 탱크(1)에서 연료가 기화되어 엔진(2) 측으로 연결되는 가스 유로(6) 사이에는 압력센서(3)가 설치되어 있는데, 이 압력센서(3)는 상기 가스 유로(6)상의 LPG 가스의 압력을 감지하는 역할을 한다.A pressure sensor 3 is installed between the gas flow passages 6 in which fuel is vaporized in the fuel tank 1 of the LPG vehicle and connected to the engine 2 side, and the pressure sensor 3 has the gas flow passage 6. It serves to detect the pressure of LPG gas on the bed.
한편 상기 압력센서(3)의 신호를 전달하는 제어 스위치(5)가 있고, 상기 제어 스위치(5)의 신호에 따라 작동되는 배기팬(4)이 차량의 후방의 하단에 설치되어 있다.On the other hand, there is a control switch 5 for transmitting the signal of the pressure sensor 3, the exhaust fan 4 which is operated in accordance with the signal of the control switch 5 is installed at the lower end of the rear of the vehicle.
이하 상기한 바와 같이 구성된 본 고안에 의한 장치의 작용을 설명하도록 한다.Hereinafter will be described the operation of the device according to the present invention configured as described above.
평소 LPG는 연료 탱크(1)에는 액체상태로 있으나 연료로 이용시 기화하여 사용된다. 그런데 이 때 가스의 이동시 가스 유로(6)의 손상 등으로 인해 가스가 누출되는 경우가 있다. 이 때 가스 유로(6)에는 평소와는 다른 압력이 형성될 것이다. 그러므로 가스 유로(6)에 설치된 압력센서(3)가 이를 감지하여 제어 스위치(5)를 온하여 차량 후방 하단에 설치된 배기팬(4)을 작동시킨다. 그럼으로써 차량내에 배출된 LPG 가스는 외부로 빠져나가게 되어 차량 안에 가스가 축적됨으로써 발생할 수 있는 사고를 미연에 방지할 수 있게 되는 것이다.LPG is usually in a liquid state in the fuel tank 1, but when used as fuel, it is used by vaporization. However, at this time, the gas may leak due to damage of the gas flow path 6 when the gas moves. At this time, a pressure different from the usual will be formed in the gas flow passage 6. Therefore, the pressure sensor 3 installed in the gas flow path 6 detects this and turns on the control switch 5 to operate the exhaust fan 4 installed in the lower rear of the vehicle. As a result, the LPG gas discharged in the vehicle is released to the outside to prevent accidents that may occur due to the accumulation of gas in the vehicle.
이제까지 설명한 바와 같이 본 고안에 의한 압력센서를 이용한 LPG 누출가스 배출장치는 LPG 차량의 연료 탱크에서 엔진 측으로 연결되는 가스 유로에 설치되어 LPG 가스의 압력을 감지하는 압력센서와, 상기 압력센서의 신호를 전달하는 제어 스위치와, 상기 제어 스위치의 신호에 따라 작동되는 배기팬을 포함하여 구성됨으로써 LPG 가스 차량에 있어서 가스의 누출시 이를 감지하여 미리 외부로 배출함으로써 차량내 가스 축적으로 인한 사고 발생을 막을 수 있는 효과가 있다.As described above, the LPG leak gas discharge device using the pressure sensor according to the present invention is installed in the gas flow path connected to the engine side from the fuel tank of the LPG vehicle to detect the pressure of the LPG gas, and the pressure sensor signal It is configured to include a control switch for transmitting and an exhaust fan operated according to the signal of the control switch to prevent the occurrence of accidents due to gas accumulation in the vehicle by detecting the gas leakage in advance in the LPG gas vehicle and discharged to the outside in advance. It has an effect.
