电磁先导阀作为气动换向阀的主要部件,在气动技术的发展中具有举足轻重的地位。以装甲螺管式电磁铁作结构形式的先导阀,又是最常见的。图1是典型的螺管式先导阀结构。螺管式电磁铁,由于其衔铁伸入到线圈的内腔,因而存在比较密集的漏磁通,而在磁场中线圈总是力图链上更多的磁通,衔铁的机械 Electromagnetic pilot valve as the main components of pneumatic valve, pneumatic technology in the development of a pivotal position. Pilot solenoid valves with armored solenoid solenoids are the most common. Figure 1 is a typical solenoid pilot valve structure. Due to its armature extends into the coil lumen, so there is a more intensive leakage flux, and in the magnetic field coil is always trying to chain more flux, the armature of the machinery
