BURKERT宝德8175型超声波液位计/宝德超声波液位计

BURKERT宝德8175型超声波液位计/宝德超声波液位计
BURKERT宝德8175型超声波液位计是一种利用介质本身的压力变化来进行自我调控，从而保持流经该被控系统的流量不变的阀门，具有流量指示，可在线调节，适用于供热及空调系统等非腐蚀性介质。运行前一次性测试调节，可使系统流量自动互定在预设置的设定直，该阀门流量调节准确，操作简单，运行平稳，可靠，使用寿命长。BURKERT宝德8175型超声波液位计工作时（即把此卸荷油道切断）．油源来油就从该路换向阀进入所控制的执行元件，工作压力大小由图中压力阀限定．采用该种卸荷方式是换向阀阀杆从中立位置→工作位置的移动过程中，卸荷油道是逐渐被关闭的，进入执行元件的油量逐渐增加，系统压力逐渐升高，执行元件启动平稳，无冲击，而且有一定调速，压力阀结构简单．其缺点是卸荷油道长，压力损失大，尤其换向阀路数多时，弊端更为突出，该种卸荷方式多用于路数较少的场合．BURKERT宝德8175型超声波液位计阀芯的移动，使工作泵的来油进入动臂油缸实现动臂上升。比例导减压阀的输出压力越大，控制主换向阀阀芯的位移越大，主换向阀通过的流量越大，动臂上升的速度越快。当操作手柄拉极限位置时，手柄中的限位电磁铁通电，手柄在极限位置被吸合。动臂以zui大的速度上升，当升动臂上位限位开关所限定的位置时，操作手柄限位电磁铁断电，手柄自动恢复到中位，动臂就可保持在所限定的位置。
