본 발명은 캐니스터(canister)의 대기측 통로를 차단/개방하는 캐니스터 클로스밸브(canister close valve)에 관한 것으로서, 특히 전자제어유닛(ECU)의 제어신호에 따라 연료계를 밀폐하는 캐니스터 클로스밸브의 기밀성을 향상시켜 전기작동을 하는 캐니스터 클로스밸브의 솔레노이드를 습분 또는 물로부터 보호/차단하면서 제품에 대한 품질향상은 물론, 기밀불량으로 인한 오작동을 방지하는 캐니스터클로스밸브의 수밀구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a canister close valve for blocking / opening an air passage of a canister, and in particular, the airtightness of a canister close valve for sealing a fuel system according to a control signal of an electronic control unit (ECU). This invention relates to a watertight structure of a canister cloth valve which improves the quality of the product as well as prevents malfunction due to poor airtightness while protecting / blocking the solenoid of the canister cloth valve which is electrically operated to improve the quality thereof from moisture or water.

일반적으로, 캐니스터 클로스밸브는 캐니스터의 대기측에 장착된 후 개방상태로 연료탱크와 대기의 교환이 자유롭게 이루어지도록 하는 환기통로 역할을 한다.In general, the canister cloth valve acts as a ventilation passage to exchange the fuel tank and the atmosphere freely after being mounted on the atmosphere side of the canister.

이러한, 캐니스터 클로스밸브는 도 1에 도시된 바와같이, 전기장에 의해 플런저(plunger)(2)를 작동시키는 솔레노이드(1)와, 상기 플런저(2)의 작동으로 부터 직선왕복운동을 하는 로드(3) 및, 상기 로드(3)의 왕복운동에 따라 연동되어 밸브의 통로(a)(b)를 기밀 또는 차단하여 연료탱크와 대기의 환기통로 역할을 수행하는 기밀판(4)으로 구성된다.As shown in FIG. 1, the canister cloth valve includes a solenoid 1 for operating a plunger 2 by an electric field and a rod 3 for linear reciprocation from the operation of the plunger 2. ), And an airtight plate 4 interlocked with the reciprocating motion of the rod 3 to seal or block the passages (a) and (b) of the valve to serve as a ventilation passage between the fuel tank and the atmosphere.

이때, 상기 캐니스터 클로스밸브는 전자제어유닛의 제어신호에 따라 폐쇄가 이루어지게 되는데, 이는 폐쇄가 이루어진 캐니스터 클로스밸브의 내부압력 변화를 계산하므로서 연료시스템의 기밀여부를 체크하여 연료의 누설여부를 검지하기 위한 것이다.At this time, the canister cloth valve is closed in accordance with the control signal of the electronic control unit, which checks the airtightness of the fuel system by calculating the change in the internal pressure of the closed canister cloth valve to detect whether the fuel is leaked. It is for.

그러나, 상기와 같은 종래의 캐니스터 클로스밸브는 연료가스 및 대기중의 습분과 항상 접촉하는 구조를 갖고 있는 바, 습분의 응축 등에 의한 부식 또는 장마철의 경우 노면의 물이 직접 캐니스터 클로스밸브로 흡입되면서 밸브의 작동불량 및 이에따른 기밀불량으로 그 수명이 짧아질뿐만 아니라 운전석의 체크엔진램프(check engine lamp)가 자주 점등되면서 소비자의 품질 만족도를 크게 저하시키는 단점을 갖고 있다.However, the conventional canister cloth valve as described above has a structure that is always in contact with the fuel gas and the moisture in the air, in the case of corrosion due to moisture condensation or rainy season, the road surface water is directly intake into the canister cloth valve valve In addition to shortening its lifespan due to poor operation and consequent airtightness, the check engine lamp of the driver's seat is frequently turned on, which has a disadvantage of greatly degrading consumer's quality satisfaction.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서 본 발명의 목적은, 솔레노이드 및 플런저의 작동시 왕복운동하는 로드의 움직임을 자유롭게 하도록 캐니스터 클로스밸브의 케이스 내면으로 고무판을 밀착하고 로드의 주변은 오링을 통해 단단하게 기밀하므로서, 전자제어유닛의 제어신호에 따라 연료계를 밀폐하는 캐니스터 클로스밸브의 기밀성을 향상시키고, 더불어 전기작동을 하는 솔레노이드를 습분 또는 물로부터 보호/차단하면서 제품에 대한 품질향상은 물론, 기밀불량으로 인한 오작동을 방지할수 있도록 하는 캐니스터 클로스밸브의 수밀구조를 제공하려는 것이다.Accordingly, the present invention has been made to solve the conventional problems as described above, the object of the present invention is to adhere the rubber plate to the inner surface of the case of the canister cloth valve to free the movement of the rod reciprocating during operation of the solenoid and plunger The periphery of the rod is tightly sealed through the O-ring, which improves the airtightness of the canister cloth valve that seals the fuel system according to the control signal of the electronic control unit, and protects / blocks the electric solenoid from moisture or water. It is to provide a watertight structure of the canister cloth valve, which can prevent the malfunction due to poor sealing as well as improving the quality.
