电磁式压力调节阀
摘要：
本发明涉及共轨系统性能测试技术领域，具体地说是一种电磁式压力调节阀，包括阀体，阀体的台阶孔中压配有导向套，阀体后端设有电磁铁，衔铁组件贯穿所述导向套与电磁铁设置并从阀体的通孔中伸出，衔铁组件后端设有隔磁盖板，在衔铁组件与隔磁盖板之间设置弹簧，紧帽将隔磁盖板、电磁铁及阀体固定连接，阀体前端设有阀座，阀座中心设有燃油通道，阀座内端面围绕燃油通道的端部设有一锥面，球通过衔铁组件压设于燃油通道上。该调节阀的阀体与电磁铁为分体结构，电磁铁可以整体更换。
摘要（英）：

The invention relates to the technical field of common rail system performance test, in particular to an electromagnetic pressure regulating valve. The electromagnetic pressure regulating valve comprises a valve body; a guiding sleeve is arranged in a stepped hole of the valve body in press fit; an electromagnet is arranged at the rear end of the valve body; an armature component penetrates through the guiding sleeve and arranged with the electromagnet and stretches out of a through hole of the valve body; a magnetism isolating cover plate is arranged at the rear end of the armature component; a spring is arranged between the armature component and the magnetism isolating cover plate; the magnetism isolating cover plate, the electromagnet and the valve body are fixedly connected through a locking cap; a valve seat is arranged at the front end of the valve body; a fuel oil channel is formed in the center of the valve seat; a conical surface is formed on the inner end face, surrounding the fuel oil channel, of the valve seat; and a ball is arranged on the fuel oil channel in a pressed manner through the armature component. According to the electromagnetic pressure regulating valve, the valve body and the electromagnet are of a split structure, and the electromagnet can be replaced entirely.
