The invention discloses an electromagnetic valve, and relates to the field of hydraulic pressure. The electromagnetic valve comprises a reset piece, an armature, a valve seat and a valve rod, a valve rod cavity is formed in the end, away from the reset piece, of the armature, the valve rod is arranged in the valve rod cavity, a first positioning part is arranged in the valve rod cavity, a second positioning part matched with the first positioning part is arranged on the valve rod to position a relative position of the valve rod and the valve rod cavity, and therefore the valve rod can move along with the armature in the axis direction of the armature so as to block or open an oil outlet. According to the electromagnetic valve, the first positioning part and the second positioning part are arranged and matched with each other, the relative position of the valve rod and the armature is determined, positioning between the valve rod and the armature is more stable, and the valve rod can still be accurately controlled according to the magnitude of electromagnetic force borne by the armature under the condition that the large flow of hydraulic oil is guaranteed.
本发明公开了一种电磁阀,涉及液压领域,电磁阀包括复位件、衔铁以及阀座,还包括阀杆,在衔铁远离复位件的一端开设阀杆腔,阀杆设置于阀杆腔内,阀杆腔内设置有第一定位部,阀杆上设置有与第一定位部配合的第二定位部,以定位阀杆和阀杆腔的相对位置,阀杆能够随衔铁沿衔铁的轴线方向运动,以封堵或者打开出油口。本发明提供的电磁阀,设置第一定位部和第二定位部,使之相互配合,确定阀杆和衔铁的相对位置,阀杆和衔铁之间的定位也更加稳定,在保证液压油大流量的情况下,阀杆仍能根据衔铁所受电磁力的大小做精准控制。
