上海喜开理切换阀 CKD切换阀的开关是由通过电磁阀来的信号压缩空气控制的。根据在流程中起的作用不同，有空气、污氮切换阀，纯氮抑制阀、污氮三通阀等。从结构型式分，有立式和卧式两种。立式切换阀又可以分为气开式和气闭式两种。气开式是指信号压缩空气断气时，阀瓣依靠自重能自动打开；反之为气闭式。气开、气闭的选择由装置的安全性确定。氮气切换阀用气开式，空气切换阀用气闭式。4GA110-M5-AC220V

喜开理切换阀的动作是由电磁阀来控制的，除了注意选择气开、气闭式，以防止气源故障带来危害之外，还应注意电磁阀状态与切换阀状态的配合，以使电源发生故障时不致危及设备安全。现分别说明如下：
1、污氮切换阀。当四通电磁阀有电时，切换阀关闭。失电时，切换阀开。而且当电源失电时，气源失压时，也能借自重打开。从而保证了出现故障时，上塔气体能通过蓄冷器放空，不致造成超压。
2、空气切换阀。当四通电磁阀有电时，切换阀打开。失电时，切换阀关闭。当控制电源故障失电时，切换阀关闭；当控制气源故障失压时，切换阀借自重关闭，保证出现故障时原料空气不进入空分塔。
3、污氮（纯氮）三通切换阀。四通电磁阀有电，三通切换阀处于排送位置；四通电磁阀失电，三通切换阀处于放空位置。当电源故障失电时，三通切换阀处于放空位置；当气源故障失压时，三通切换阀能借自重处于放空位置。
