본 발명은 자동차의 우발적인 사고로 인한 차량의 전복되거나 수평상태에서 ±75°이상 기울어졌을 경우에 자동차의 연료가 누출되는 것을 방지할수 있도록 장착하는 자동차의 연료누출 방지용 체크밸브에 관한 것이다.The present invention relates to a check valve for preventing fuel leakage of a vehicle mounted to prevent leakage of fuel in a vehicle when the vehicle is overturned or tilted more than ± 75 ° in a horizontal state due to an accident of the vehicle.

특히, 가솔린과 같은 자동차의 연료는 누출될 경우에 화재가 발생하게 되므로서 많은 인명과재산의 손실을 가져올수 있는 것이므로, 연료의 누출방지에 더욱 신경을 써야 하는 것이다.In particular, the fuel of automobiles such as gasoline can cause a lot of human life and property loss as a fire occurs in case of leakage, more attention should be paid to preventing the leakage of fuel.

그러나, 종래에 사용되던 자동차의 연료 누출 방지용 체크밸브는 어떠한 경우라도 기능상 자동차의 길이방향의 직각방향으로 장착되어야만 정상적으로 제기능을 발휘할 수 있었기 때문에 장착부위가 엔진룸내로 한정되는 단점이 있었다.However, the fuel leakage preventing check valve of the vehicle used in the prior art had a disadvantage in that the mounting portion is limited to the engine room because it can be normally functioned only when it is mounted in a right angle direction in the longitudinal direction of the vehicle in any case.

즉, 종래의 체크밸브는 첨부 도면 제3도에 도시된 바와같이 일측에 고정부재(2)를 형성시킨 밸브몸체(1) 내부에 제1변실(3)을 형성하여 그 단부에 공급관(4)이 취부되게 하고, 상기 공급관(4)과 직각으로 제2변실(6)을 가진 배출관(5)을 취부하였으며, 제1변실(3)과 제2변실(6)내에는 변구(7)(7-1)를 각각 삽입 착설하여서 구성되는 것이다.That is, in the conventional check valve, as shown in FIG. 3, the first valve chamber 3 is formed inside the valve body 1 in which the fixing member 2 is formed on one side thereof, and the supply pipe 4 is formed at the end thereof. The discharge pipe 5 having the second toilet 6 at right angles to the supply pipe 4 was mounted, and the first toilet 3 and the second toilet 6 were provided with a spout 7 and 7. -1) is constructed by inserting and installing each.

이러한 종래의 체크밸브는 제1변실(3)의 유로(3a)와 제2변실(6)의 유로(6a)가 직각으로 만나도록 이루어지며, 두유로(3a)(6a)는 밸브몸체(1)의 수평축(8)에 대하여 등각으로 기울어지면서 자동차의 전후방향축에 직각을 이루도록 고정부재(2)로서 자동차의 엔진룸내에 장착되는 것이다.This conventional check valve is made so that the flow path (3a) of the first side chamber (3) and the flow path (6a) of the second side chamber 6 meet at a right angle, the two flow paths (3a), (6a) is the valve body (1) It is mounted in the engine room of the vehicle as the fixing member 2 so as to be perpendicular to the horizontal axis 8 of the vehicle while being inclined at an angle with respect to the horizontal axis (8).

따라서, 상기와 같은 종래의 연료누출 방지용 체크밸브를 장착시킨 자동차가 정상적인 상태를 유지할때는 제1변실(3)과 제2변실(6)의 변구(7)(7')가 모두 개방상태로서 연료를 공급하게 되는 것으로, 만약에 자동차가 우발적 사고에 의해 좌측으로 기울었을때는 제2변실(6)은 개방상태가 되지만 제1변실(3)이 폐쇄되고, 자동차가 우측으로 기울었을때는 제1변실(3)은 개방상태가 되지만 제2변실(6)은 폐쇄되며, 자동차가 전복되어 뒤집힌 경우에는 제1변실(3)과 제2변실(6)이 모두 폐쇄되어 유로(3a)(6a)가 차단되는 것이다.Therefore, when the vehicle equipped with the conventional fuel leakage prevention check valve as described above maintains the normal state, the valves 7 and 7 'of the first and second side chambers 3 and 6 are open as fuel. If the car is inclined to the left by accidental accident, the second toilet 6 will be open but the first toilet 3 will be closed and the car will be inclined to the right. (3) becomes open, but the second toilet 6 is closed. When the vehicle is overturned and overturned, both the first toilet 3 and the second toilet 6 are closed so that the flow paths 3a and 6a are closed. It is blocked.

이러한 종래의 체크밸브는 자동차가 우발적사고에 의해 좌측 또는 우측으로 기울어지나 뒤집힌 경우의 세가지 자세에서 모두 유로를 차단할수 있도록 2개의 밸브를 직렬로 연결 배열하고 이들이 특정한 자세를 갖도록 특히, 엔진룸내에 취부하여야만 제기능을 발휘할수 있었던 것이다.These conventional check valves are arranged in series so that two valves can be connected in series so as to shut off the flow path in all three positions when the vehicle is inclined to the left or the right side due to an accidental accident or is reversed. Only if it could function properly.

그러나, 최근의 자동차의 개발방향과 수요자의 욕구등에 의하여 특정부품의 탑재나 자동차의 고급화에 따른 장비의 탑재 또는 이들 부품이나 장치의 설치에 따른 상호간섭등에 의하여 엔진룸의 공간이 점차 협소해지므로서, 엔진룸내의 사용가능한 공간이 작아지고 있기 때문에 룸내의 연료누출 방지용 체크밸브는 그 사용에 많은 어려움과 문제점이 수반되었던 것이다.However, due to the recent development direction of the vehicle and the desire of the consumer, the space of the engine room is gradually narrowed due to the mounting of specific parts, the equipment according to the advanced cars, or the mutual interference caused by the installation of these parts or devices. As the available space in the engine room is becoming smaller, the check valve for preventing fuel leakage in the room has been accompanied with many difficulties and problems in its use.

본 발명은 상술한 바와같은 종래의 연료누출 방지용 체크밸브의 장착에 따른 제반 문제점과 어려움을 해결하기 위하여 창출된 것이다.The present invention has been created to solve the problems and difficulties caused by the conventional installation of the fuel leakage prevention check valve as described above.

본 발명 체크밸브의 작동자세는 종래의 것과 동일하게 유지하면서도 취부환경에 따라 적절하게 적용시켜 장착사용할수 있도록, 각변실에 직각되게 예비 유로를 증설하여 공급관과 배출관의 위치를 조절 취부할수 있게끔 구성하므로서 장착부위의 공간에 따라 체크밸브의 구성을 임의의 형태로 적용 구성하여 장착이 간편할 뿐만 아니라, 어떠한 장착부위에서도 충분히 제기능을 발휘할수 있도록 된것이다.The operation position of the check valve of the present invention is configured to be able to adjust the position of the supply pipe and the discharge pipe by adding a preliminary flow path perpendicular to each side chamber so that it can be installed and used appropriately according to the mounting environment while maintaining the same as the conventional one. According to the space of the mounting part, the check valve can be applied in any form to make it easy to install and fully functional at any mounting part.
