ODE两位两通电磁阀,意大利ODE型号21A5ZV45D
原理:通电时,电磁线圈产生电磁力把关闭件从阀座上提起,阀门打开;
断电时,电磁力消失,弹簧把关闭件压在阀座上,阀门关闭。
特点:在真空、负压、零压时能正常工作,但通径一般不超过25mm。
2)分步直动式电磁阀:
原理: 它是一种直动和导式相结合的原理,当入口与出口没有压差时,
通电后,电磁力直接把导小阀和主阀关闭件依次向上提起,阀门打开。
当入口与出口达到启动压差时,通电后,电磁力导小阀,主阀下腔压力上升,上腔压力下降,
从而利用压差把主阀向上推开;断电时,导阀利用弹簧力或介质压力推动关闭件,向下移动,使阀门关闭。
2 way normally closed solenoid valves with pilot control have
an inlet pipe and a outlet pipe. The main orifice, in the body,
diaphragm there is pressure only in the area external to the
main orifice: thus the resultant of the forces on the diaphragm
is such as to push it and close the main orifice. When the coil
is energized, movement of the plunger, on which a gasket is
mounted, causes opening of the pilot orifice and discharging
of the chamber above the diaphragm: the pressure unbalance
moves the diaphragm which opens the main orifice.
is opened by the effect of an unbalance in pressure between
