摘要
通过借鉴传统的二通插装阀,研发专门针对注塑机行业的一种新型的先导式主动型带位置监测安全阀,利用电磁换向阀的通、断控制先导油向主阀控制油腔供油,实现主安全阀的强制打开,并通过位置监测开关的指示灯显示主阀的通断关系,监控插装阀动作,为判断液压回路故障和执行元件安全保护提供信号。
By referring to the traditional two-way cartridge valve, The essay developed a new pilot active belt position monitoring safety valve specialized in the injection molding machine industry, using electromagnetic directional valve to control pilot oil supplying oil for the main valve control oil cavity and force the main safety valve open, and through position monitoring switch indicator light shows the main valve broken relationships, monitors valve action, and provides a signal for determining the hydraulic circuit＇ s fault and execute element＇ s safety.
