DBETE-6X/420G24K31F1V比例溢流阀

电液比例溢流阀

组成:

比例电磁铁 直动式溢流阀主体

工作原理:

输入一I，产生一电磁力，作用于阀心上，得到- -控制压力，其pI, I变化，p也变化。

比例溢流阀的压力控制阀

比例溢流阀的特点是调定的压力与输入电流大小成正比，即输入的电流大，调定的压力高。

当通过计算机键盘输入被折板料的抗拉强度，厚度，长度以及下模V型槽开口宽度后，计算机按折弯力计算公式求得所需折弯力，经数模转换后，通过控制比例溢流阀的电控器，向比例溢流阀输入适当的电流值，从而达到控制折弯力大小的目的。板料折弯机所需小折弯力和允许的大折弯力要与比例溢流阀的压力特征曲线相对应，并且使调定的压力稍大于所需折弯力，以利于板料的顺利折弯。

比例溢流阀的压力控制一般为开环，如接入压力传感器，可进行闭环控制。

DBETE-6X/420G24K31F1V比例溢流阀

DBET 型比例溢流阀是带座设计的遥控阀，用于系统压力限制。通过带有中心螺纹和可拆卸线圈的比例电磁铁进行操作。电磁阀的内部连接到端口 T 或 Y，并充满液压油。根据电气控制值，这些阀门可用于无级设置系统压力限制。阀门主要由壳体（1）、比例电磁铁（2）、阀座（3）和阀芯（4）组成。

为了设置系统压力，在控制电子装置上指定了一个控制值。根据控制值，电子设备以电流驱动电磁线圈。比例电磁阀将电流转换为机械力，通过电枢柱塞 (5) 作用在阀芯 (4) 上。阀芯 (4) 推到阀座 (3) 上并阻塞 P 和 T 或 Y 口之间的连接。如果阀芯 (4) 上的液压力等于电磁力，阀门通过提升来控制设定压力阀座 (4) 离开阀座 (3)，从而使液压油能够从端口 P 流到 T 或 Y。如果控制值为零，则控制电子设备仅将*小控制电流施加到比例电磁阀 (2 ) 并设置*小设定压力。
