安沃驰AVENTICS换向阀工作时借着阀外的驱动传动机构转动驱动轴,带动摇拐臂,启动阀板,使工作流体时而从左入口通向阀的下部出口,时而从右入口变换通向下部出口,
实现了周期变换流向的目的。利用阀芯对阀体的相对运动,使油路接通、关断或变换油流的方向,从而实现液压执行元件及其驱动机构的启动、停止或变换运动方向。
安沃驰AVENTICS换向阀特点是启动力较大,换向时间短,价廉。但当阀芯卡住或吸力不够而使铁芯吸不上时,电磁铁容易因电流过大而烧坏,故工作可靠性较差,动作时有冲击,寿命较低。
直流电磁铁电压一般为24伏。其优点是工作可靠,不会因阀芯卡住而烧坏,寿命长,体积小,但启动力较交流电磁铁小,而且在无直流电源时,需整流设备。为了提高电磁换向阀的工作可靠性和寿命,
近年来,国内外正日益广泛地采用湿电磁铁,这种电磁铁与滑阀推杆间无须密封,安沃驰AVENTICS换向阀消除了O形密封圈处的摩擦力,它的电磁线圈外面直接用工程塑料封固,不另作金属外壳,
这样既保证了绝缘,又利于散热,所以工作可靠,冲击小,寿命长。电磁换向阀只是采用电磁铁来操纵滑阀阀芯运动,而阀芯的结构及型式可以是各种各样的,所以电磁滑阀可以是二位二通、
二位三通、二位四通、三位四通和三位五通等多种型式。安沃驰AVENTICS换向阀一般二位阀用一个电磁铁,三位阀需用两个电磁铁。是利用电磁铁推动阀芯来控制液流方向的。
采用电磁换向阀可以使操作轻便,容易实现自动化操作,因此应用极广。
