R900410876四通换向阀的结构与工作原理1、四通换向阀的构成四通换向阀主要由四通气动换向阀（主阀）、电磁换向阀（控制阀）及毛细管组成。主阀内由滑块、活塞组成活动阀芯，主阀阀体两端有通孔可使两端的毛细管与阀体内空间相连通，滑块两端分别固定有活塞，活塞两边的空间可通过活塞上的排气孔相通。控制阀由阀体和电磁线圈组成。阀体内有针型阀芯。主阀与控制阀之间有三根（或四根）毛细管相连，形成四通换向阀的整体。2、四通换向阀的工作原理,主阀的管口（4）连接于压缩机高压排气口，管口（2）连接于压缩机低压吸气口。（1）、（3）两个管口分别连接蒸发器的出气口和冷凝器的进气口。（3）接冷凝器进气口，（1）接蒸发器出气口。当电磁阀不通电时，系统工作于制冷状态，控制阀因弹簧1的作用，阀心移至左端，处于释放状态，此时毛细管E与C连通。因为E接在低压吸气管上，所以毛细管C及主阀内左端空间均为低压，高压气体由主阀管口4进入主阀，经活塞I的排气孔使主阀内的右端空间成为高压，推动主阀阀芯移至左端，管口2与管口1连通而管口4与管口3连通，系统形成制冷循环状态。当电磁阀通电时，电磁力吸动控制阀阀芯向右移动，毛细管E与D相连。主阀内右端空间成为低压，高压气体经活塞II的排气孔进入主阀内左端空间，推动阀芯移向右端，管口2与管口3连通而管口4与管口1连通，蒸发器、冷凝器的功能对换，系统转换成制热循环状态。公司名称：武汉晨丰机电设备有限公司武汉晨丰机电设备有限公司欢迎您的来电！联系人：王亚询价热线：027-87183955/87183108
