DREBE6X-1X/175MG24K31A1M比例减压阀

特点

1)可实现压力、速度的无极调节，避免了常通的开关式气阀换向时的冲击现象。

2)能实现远程控制和程序控制。

3)与断续控制相比，系统简化，元件大大减少。

4)与液压比例阀相比，体积小、重量轻、结构简单、成本较低，但响应速度比液压系统慢得多，对负载变化也比较敏感。

5)使用功率小、发热少、噪声低。

6)不会发生火灾，不污染环境。受温度变化的影响小。

比例阀三种形态

（1）电磁式 电磁式是指采用比例电磁铁作为电气一机械转换元件的比例阀，比例电磁铁将输入的电流信号转换成力、位移机械信号输出．进而控制压力、流量及方向等参数。

（2）电动式 电动式是指采用直流伺服电动机作为电气一机械转换元件的比例阀，直流伺服电动机将输入的电信号．转换成旋转运动转速，再经丝杆螺母、齿轮齿条或齿轮凸轮等减速装置和变换机构，输出力与位移，进一步控制液压参数。

（3）电液式 电液式是指采用力矩马达和喷嘴挡板的结构为先导控制级的比例阀。对力矩马达输入不同的电信号，并通过同它连接在一起的挡板（有时力矩马达的衔铁就是挡板）输出位移或角位移，改变挡板和喷嘴之间的距离，使喷嘴喷出的油液流阻产生变化，进而控制输小参数。

内控内泄顺序阀与外控顺序阀

内控内泄顺序阀的图形符号和工作原理与溢流阀相同。

多串联在液压系统的回油路上，使回油具有一定压力。

外控内泄顺序阀等同于二位二通阀，可作卸载阀。

外控外泄顺序阀可作液动开关和限速锁。

压力继电器

压力继电器是一种将液压系统的压力信号转换为电信号输出的元件。

其作用是实现执行元件的顺序控制或安全保护。
