The present invention relates to a fuel tank isolation valve, in which a locking groove is formed at the lower end of a solenoid pot and the end of a core plate is inserted into the locking groove to support the lower end of the solenoid pot, so as to prevent the deformation of the solenoid pot due to injection pressure during injection molding of a solenoid housing. Therefore, shape defects in the product are prevented, and a decrease in magnetic force is prevented by preventing a gap between the core and the solenoid pot.
본 발명은 연료탱크 차단밸브에 관한 것으로, 솔레노이드팟의 하단부에 걸림홈이 형성되고, 코어 플레이트의 단부가 상기 걸림홈에 삽입되어 솔레노이드팟의 하단부를 지지함으로써 솔레노이드하우징 사출 성형시 사출압력에 의한 솔레노이드팟의 변형이 방지된다. 따라서 제품의 형상 불량이 방지되고, 또한 코어와 솔레노이드팟 사이에 간극이 발생하지 않게 됨으로써 자기력 감소 현상이 방지된다.
