본 고안은 차량 전복시의 연료탱크 연료누출 방지구조에 관한 것으로, 특히 차량의 충돌이나 운전 부주의등으로 인한 차량의 전복사고시 연료탱크로부터 연료가 누출되는 것을 방지하여 차량의 폭발위험과 치명적인 인명피해를 방지할 수 있도록 된 차량 전복시의 연료탱크 연료누출 방지구조에 관한 것이다.The present invention relates to a fuel tank fuel leakage prevention structure when the vehicle is overturned. In particular, it prevents fuel from leaking from the fuel tank when the vehicle is overturned due to a collision or inadvertent driving of the vehicle, thereby reducing the risk of explosion and fatal injury to the vehicle. The present invention relates to a fuel tank fuel leakage preventing structure when the vehicle is overturned.
일반적으로 연료탱크는 본체와, 그 외부에 연료 주입구, 연료 파이프, 연료복귀 파이프, 연료 에미션 파이프, 연료 게이지의 센더 유니트등이 구성되어 있고, 내부에는 차량 주행시 연료의 요동을 방지함과 동시에 탱크의 강도를 증가시키기 위한 격리판이 접합고정되어 있으며, 탱크의 내면은 산화부식을 방지하기 위하여 방청처리되어 있다.In general, the fuel tank is composed of a main body, a fuel inlet, a fuel pipe, a fuel return pipe, a fuel emission pipe, a sender of a fuel gauge, and the like while preventing a fuel fluctuation while driving a vehicle. The separator is bonded to increase the strength of the tank, and the inner surface of the tank is rustproofed to prevent oxidation corrosion.
또한 상기에서 연료 주입구의 캡에는 탱크내부에 부압이 형성되어 기화기나 연료분사 시스템에 연료가 원활하게 공급되지 않는 것을 방지하기 위하여 압력밸브와 부압밸브(진공밸브)가 설치되어 있으며, 연료 에미션 파이프(fuel emission pipe)는 탱크와 차콜 캐니스터 사이를 연결하는 것으로써, 탱크내에서 발생한 증기를 캐니스터로 흡수시키는 통로 역할을 한다.In addition, the cap of the fuel inlet is provided with a pressure valve and a negative pressure valve (vacuum valve) in order to prevent a negative pressure is formed in the tank to prevent the fuel from being supplied smoothly to the vaporizer or the fuel injection system, the fuel emission pipe (fuel emission pipe) is a connection between the tank and the charcoal canister, serves as a passage for absorbing the vapor generated in the tank to the canister.
연료 파이프는 방청처리된 강관이 사용되며, 파이프내에 베이퍼 록(vapour lock)현상이 발생하지 않도록 열이 적은 곳에 배관되어 있다.The fuel pipe is made of rust-proof steel pipe, and is piped in a place where heat is low so that vapor lock does not occur in the pipe.
그러나 이와 같이 연료탱크에는 다수의 파이프가 연결설치되어 있기 때문에 차량의 충돌 또는 전복사고시와 같은 위험발생시 매우 취약하고, 특히 차량의 전복시에는 연료탱크가 뒤집혀지면서 각 파이프의 이탈파손이 발생하여 연료가 누출되는 경우가 빈번한 것은 물론, 고열의 엔진 실린더 주위와 각종 전기장치에 휘발성이 강한 연료가 접촉되어 연료탱크와 차량이 폭발되는 문제점이 있었고, 더욱이 이러한 폭발사고에 따라 운전자와 탑승자가 사망이나 중상등 치명적인 피해를 입는 문제점이 있었다.However, since a large number of pipes are connected to the fuel tank, it is very vulnerable in case of danger such as a collision or rollover of the vehicle, and especially when the vehicle is overturned, the fuel tank is inverted, causing breakage of each pipe, resulting in fuel failure. As well as frequent leaks, fuel tanks and vehicles were exploded due to highly volatile fuels coming into contact with high-temperature engine cylinders and various electrical devices.Furthermore, these accidents resulted in death or serious injury to drivers and passengers. There was a problem of fatal damage.
본 고안의 목적은 차량의 충돌 또는 전복사고시 연료탱크로부터 연료가 누출되는 것을 막아 차량의 폭발은 물론, 운전자와 탑승자와 치명적인 피해를 입게 되는 것을 방지하기 위한 것이다.An object of the present invention is to prevent fuel from leaking from the fuel tank during a vehicle crash or rollover accident, as well as to prevent the vehicle from being damaged, as well as fatal damage to the driver and passengers.
본 고안은 이러한 목적달성을 위하여 연료탱크가 뒤집혀져 각 배관이 파손된 상태에서 연료탱크로부터의 연료가 누출되는 것을 방지할 수 있도록 연료탱크내에 위치하는 각 배관에 고무 가스킷이 부착된 합성수지재의 차단밸브를 회동가능케 설치하여 차량의 전복사고시 차단밸브가 연료탱크의 각 배관을 폐쇄시킴으로써 연료가 누출되는 것을 방지하는 것이 특징이다.In order to achieve this purpose, the present invention is a synthetic resin shutoff valve having a rubber gasket attached to each pipe located in the fuel tank to prevent the fuel tank from being inverted and leaking fuel from the fuel tank when each pipe is broken. Rotor is installed to prevent the fuel leakage by closing the shut-off valve of each fuel tank in the vehicle overturn accident.
이하, 본 고안의 구체적인 실시예를 도면을 참조하여 상세히 설명한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.
제1도는 일반적인 연료탱크의 사시도이고, 제2도는 본 고안 연료탱크의 연료누출 방지를 위한 차단밸브가 부착된 파이프 조립체의 요부확대 사시도이며, 제3도는 본 고안 연료탱크의 연로누출 방지구조를 보인 요부확대 측단면도서, 연료탱크(11)와, 연료탱크(11)와 통하여 그 외부에 연결설치된 다수의 파이프(12)와, 연료탱크(11)내에 위치된 각 파이프(12)의 하단일측에 돌출형성된 지지돌기(13)와, 상기 지지돌기(13)의 하단에 힌지핀(14)으로 회동용이하게 연결설치된 합성수지재의 차단밸브(15)와, 차단밸브(15)의 상면에 부착되어 차량의 전복사고시 차단밸브(15)와 함께 파이프(12)에 닫혀 연료탱크(11)내의 연료가 각 파이프(12)의 연결부 틈새를 통해 외부로 누출되는 것을 방지하는 고무재질의 패킹(16)으로 구성된 것이다.FIG. 1 is a perspective view of a general fuel tank, and FIG. 2 is an enlarged perspective view of a main part of a pipe assembly with a shutoff valve for preventing fuel leakage of a fuel tank of the present invention, and FIG. 3 is a fuel leakage preventing structure of the fuel tank of the present invention. Enlarged sectional side view of the main part, on the fuel tank 11, a plurality of pipes 12 connected to the outside through the fuel tank 11, and the lower end of each pipe 12 located in the fuel tank 11 The protruding support protrusion 13 and the shutoff valve 15 of the synthetic resin material which are installed to be pivotally connected to the lower end of the support protrusion 13 by the hinge pin 14 are attached to the upper surface of the shutoff valve 15. It is composed of a rubber packing 16 which is closed to the pipe 12 together with the shutoff valve 15 to prevent the fuel in the fuel tank 11 from leaking to the outside through the gap of the connection portion of each pipe 12 in the event of a full roll accident. .
따라서 본 고안은 제1도 내지 제3도의 (a)에서 보는 바와 같이, 차량의 정상 주행시에는 각 파이프(12)를 통해 연료탱크(11)의 연료공급 및 연료회수동이 이루어지게 되고, 이때 연료탱크(11)내에 위치되는 각 파이프(12)에 힌지핀(14)으로 연결된 차단밸브(15)는 그 자중에 의해 하방으로 개방된 상태를 유지하게 된다.Therefore, the present invention, as shown in (a) of Figures 1 to 3, during the normal driving of the vehicle, the fuel supply and fuel recovery of the fuel tank 11 is made through each pipe 12, at this time the fuel tank The shutoff valve 15 connected by the hinge pin 14 to each pipe 12 located in the (11) is kept open downward by its own weight.
여기서 차량의 충돌 또는 전복사고등이 발생하여 연료탱크(11)가 뒤집혀지면서 연료탱크(11)에 연결설치된 각 파이프(12)가 이탈, 파손되면, 이때 제3도의 (b)와 같이 차단밸브(15)가 자중에 의해 닫힘과 동시에 고무재질의 패킹(16)둘레면이 파이프(12)의 홀에 밀착되고, 따라서 파이프(12)를 폐쇄, 차단함으로써 연료탱크(11)로부터의 연료가 외부로 누출되는 것을 방지할 수 있게 되며, 아울러 차량의 폭발사고위험을 미연에 제거하여 운전자나 탑승자의 신체 사상사고와 같은 더이상의 사고위험을 방지할 수 있게 된다.Here, when the fuel tank 11 is inverted and the pipes 12 connected to the fuel tank 11 are separated or damaged due to a collision or a rollover accident of the vehicle, the shutoff valve (b) of FIG. 15 is closed by its own weight, and the rubber 16 packing surface is in close contact with the hole of the pipe 12. Therefore, the fuel from the fuel tank 11 is brought to the outside by closing and blocking the pipe 12. The leak can be prevented, and the risk of explosion of the vehicle can be eliminated in advance to prevent further accident risks such as bodily accidents of the driver or passenger.
이와 같이 본 고안은 연료탱크의 각 파이프 하단에 차단밸브를 회동가능케 연결설치함으로써 차량의 충돌이나 전복등과 같은 사고에 따라 연료탱크가 뒤접혀 각 파이프가 이탈, 파손되는 겨우 차단밸브에 의해 각 파이프를 차단시켜 연료가 외부로 누출되는 것을 방지할 수 있고, 따라서 차량의 폭발사고나 운전자 또는 탑승자의 신체 사상사고를 대폭 경감시킬 수 있데 된 것이다.As such, the present invention is connected to the lower end of each pipe of the fuel tank so that the shutoff valve can be rotated so that the fuel tank is folded over and the pipe is detached and damaged due to an accident such as a vehicle collision or overturning. By preventing the fuel from leaking to the outside to prevent the explosion of the vehicle or the accident of the driver or the rider can significantly reduce the accident.
