The invention relates to a solenoid valve, which comprises a valve body and a valve component, wherein a fluid channel and a containing cavity are arranged in the valve body; the valve component is installed in the containing cavity; the fluid channel and the containing cavity communicate; the valve component comprises a valve core seat, a valve core, a driving mechanism and a sealing shell, wherein the valve core seat is installed on the bottom of the containing cavity; the valve core is cooperated with the valve core seat for opening or closing the fluid channel; the driving mechanism drivesthe valve core to carry out reciprocating motion; the sealing shell and the containing cavity form a sealed space; the driving mechanism comprises a lead screw and a driving element capable of driving the lead screw to rotate; an axial through hole is arranged in the valve core; the lead screw and the axial through hole are connected through a thread; the rotation of the lead screw is converted into the straight line motion of the valve core through the thread; the lead screw and/ or valve core is provided with a pressure balance channel; and fluid which enters the valve body passes through the pressure balance channel to fill a cavity body where the upper end surface and the lower end surface of the valve core are positioned. Compared with the prior art, the solenoid valve has the advantages that the valve core can be easily driven, the valve body is miniaturized, flow regulation is accurate and stable and the like.

    本发明涉及一种电磁阀,包括内部设有流体通道和容纳腔的阀体以及安装于容纳腔内的阀组件,流体通道和容纳腔连通;阀组件包括安装于容纳腔底部的阀芯座、与阀芯座配合用于关闭或打开流体通道的阀芯、驱动阀芯往复运动的驱动机构以及与容纳腔形成密封空间的密封壳体;驱动机构包括丝杆和带动丝杆转动的驱动元件,阀芯的内部设有轴向通孔,丝杆和轴向通孔通过螺纹连接,该螺纹将丝杆的转动转化为阀芯的直线运动;丝杆和/或阀芯上设有压力平衡通道,进入阀体的流体经过压力平衡通道充满阀芯的上端面和下端面所在的腔体。与现有技术相比,本发明具有阀芯容易驱动、阀体小型化、流量调节精确稳定等优点。
