意大利先导式电磁阀,ODE型号21T2BV22-F
在这个电磁阀系列中必须有一个小值入口管和出口管之间的压差确保电磁阀正常工作。
但入口之间的压差过大和出口,与2路常开直接作用的底部无阀,
导致所需的力的增加打开导向孔,所以如果这个压力差是大于螺线管的值
阀门已经设计,后者可能不会重新打开均匀当线圈未通电时。
为了正确操作电磁阀,并避免隔膜的快速磨损,建议启动阀关闭,
the latter may open even when
the coil is not energized. Proportional solenoid valves are tared
individually, at the moment of installation and inspection testing,
with the adjustment screws in the fixed core: any modification of
this taring may make the valve work in a different way with
regard to the data shown on the label.
实际流量不高于Kv(即流量通过压力损失为1巴的阀门)。
因此,阀门打开时入口压力应高于1巴不宜使用具有自由出口的阀门本身,
即没有出口限制,使压降降至1巴的值。
此外,在设计液压回路时,必须特别注意问题可能引起超压,
如撕裂隔膜或水锤损坏电磁阀的其他部分。
causes a reduction in the pressure
required to open the valve: if the pressure difference between
inlet and outlet is greater than the maximum value for which the
solenoid valve has been tared,
比例直动电磁阀具有入口管和出口管。
安装有密封垫圈的柱塞直接用于打开和关闭主孔电磁阀。
不同于只有2路常闭电磁阀两种状态,
开和关,比例电磁阀,in线圈中电流运行的功能可以部分打开。
On these valves, unlike the other models, the fluid shall enter
into the valve so to pass through the main orifice from the lower
side towards the higher one.
In this family of solenoid valves an increase in pressure, as with
three way solenoid valves,
