<p>A normally open solenoid valve and an assembling method thereof are provided. The normally open solenoid valve includes a valve body component (2) and a coil component (1). A fixed iron core assembly (25), a movable iron core component (22) being axially movable under an electromagnetic force and a seal component (257')are disposed in a sleeve of the valve body component (2). The seal component abuts against or separates from a valve port so as to open or close the solenoid valve. The fixed iron core assembly (25) includes a fixed iron core component (251) and a transmission component being axially slidable relative to the fixed iron core component (251). The seal component is disposed at a lower end of the transmission component, and an upper end of the transmission component directly or indirectly contacts with the movable iron core component, thereby driving the seal component to abut against or separate from the valve port. The design of the structure of the present invention is reasonable and reliable, and the whole assembling is more convenient, and the difficulty for machining is reduced. Moreover, a standardization design of the fixed iron core assembly may be realized so as to reduce the controlling steps during assembling, which substantially reduces the errors in assembling.</p> |
