电动调节阀
摘要
一种电脑控制的带先导阀的电动调节阀,在主阀上装一先导阀,在阀门从关闭装态开启时先打开先导阀,使主阀上下压力平衡后再打开主阀。为了消除累积误差和对阀门上下死点进行控制,在驱动阀杆的蜗杆上装有一个传感器,其上有三个控制点,计算机可以通过此三点控制调节阀的上死点,下死点和消除累积误差。驱动电动机上还装有一个传感器,电脑可以通过此传感器对阀门位置和速度进行测量和控制。

1.一种电动调节阀,特别是一种电脑控制的带先导阀的电动调节阀。其特征在于在主阀上装一先导阀,阀门开启时先打开先导阀,再打开主阀,在主阀与阀杆间装有一弹簧,在阀杆上行时,阀杆直接带动主阀,下行时阀杆通过弹簧推动主阀,先导阀由一个滑套固定,在先导阀与阀杆之间装有一个弹簧,开启阀门时阀杆通过滑套打开先导阀,关闭时通过弹簧使先导阀关闭严密又不使阀杆顶死,在驱动阀杆的螺杆上装有一个传感器,计算机可以通过此传感器控制调节阀的上死点,下死点和消除累积误差,驱动电动机上还装有一个传感器,电脑可以通过此传感器对阀门位置和速度进行测量和控制。
