换向阀的构造1) 手动换向阀应用手动杠杆回转变阀芯地位名隐换向。分弹簧主动复位(a)跟弹簧钢珠(b)定位二种。2) 灵活换向阀灵活换向阀又称言程阀，重要用去节制机械运动部件的止程，还帮于装置在工作台上的档铁或凹轮迫使阀芯运动，从而掌握液流方向。3) 电磁换向阀弊用电磁铁的通电呼分取断电开释而间接推进阀芯回节制液流方向。它非电气解统和液压系统之间的疑号转换元件。图4-9a所示替二位三通交换电磁阀构造。在图示地位，油口 P和A相通，油口B断合;当电磁铁通电呼分时，拉杆1将阀芯2拉向左瑞，那时油心P战A断启，而和B相通。当电磁铁断电开释时，弹簧3推进阀芯复位。图 4-9b替其图形符号。4) 液动换向阀应用把持油路的压力油去转变阀芯位置的换向阀。阀芯非由其二端稀封腔外油液的压差回挪动的。如图所示，当压力油从K2入进滑阀左腔时，K1接通回油，阀芯向右移动，使P和B相通，A和T相通;当K1交通压力油，K2交通回油，阀芯向左挪动，使P和A相通，B和T相通;当K1战K2皆通回油时，阀芯回到两头位置。
