Two-position and three-way solenoid valve

一种两位三通电磁阀

Abstract

The invention relates to the technical field of valves, in particular to a two-position and three-way solenoid valve. The two-position and three-way solenoid valve comprises a shell, an electromagnetic driving component, a reset spring, a moving iron core, a push rod, a valve and a valve holder, wherein a limiting groove is formed in one end, which is close to the push rod, of the moving iron core, an adjusting shim is arranged in the limiting groove, and the corresponding end of the push rod is inserted into the limiting groove. According to the two-position and three-way solenoid valve, the limiting groove is formed in one end, which is close to the push rod, of the moving iron core, the adjusting shim is arranged in the limiting groove, the corresponding end of the push rod is positioned in the limiting groove, and therefore, the length dimension deviation of the push rod and the moving iron core can be made up by the adjusting shim in a manufacturing process, thereby realizing correction of rejected products and solving the problems of difficulty in controlling over precision and large manufacturing difficulty of an existing two-position and three-way solenoid valve.
本发明涉及阀门技术领域,特别是涉及到了一种两位三通电磁阀。该两位三通电磁阀包括壳体、电磁驱动部件、复位弹簧、动铁芯、推杆、活门以及活门座,所述动铁芯的靠近推杆的一端处设有限位槽,限位槽中设有调整垫片,推杆的相应端插入至所述限位槽中。由于本发明的两位三通电磁阀的动铁芯的靠近推杆的一端设有限位槽,限位槽中设有调整垫片,并且推杆的相应端位于所述限位槽中,因此,在制造的过程中,推杆以及动铁芯所存在的长度尺寸偏差可通过调整垫片来弥补,从而可实现不合格产品的修整,进而解决现有的两位三通电磁阀存在的精度不易控制和制造难度大的问题。
