REXROTH比例方向阀是工业过程自动化控制系统用的执行器,它在接受电控信号后能自动开启或关闭阀门,实现对管道中流体介质的通断或流量调节控制从而对次同中的温度、流量、压力等参数进行自动调节或远程控制。
REXROTH比例方向阀产品可广泛应用于纺织、印刷、化工、塑料、橡胶、制药、食品、建材、机械、电器、表面处理等生产和科研部门以及浴室、食堂、空调等人们日常生活设施中,ZQDF系列主要用于空气、蒸汽、煤气等气体介质的控制;ZQDF-Y系列电磁阀主要用于自来水、蒸馏水、冷冻盐水、电镀废液等液体介质,同时也用于粘度小于4°E的油类。
REXROTH比例方向阀的工作原理:电磁阀里有密闭的腔,在不同位置开有通孔,每个孔都通向不同的油管,腔中间是阀,两面是两块电磁铁,哪面的磁铁线圈通电阀体就会被吸引到哪边,通过控制阀体的移动来档住或漏出不同的排油的孔,而进油孔是常开的,液压油就会进入不同的排油管,然后通过油的压力来推动油刚的活塞,活塞又带动活塞杆,活塞竿带动机械装置动。这样通过控制电磁铁的电流就控制了机械运动。 实际上,根据流过介质的温度,压力等情况,比如管道有压力和自流状态无压力。电磁阀的工作原理是不一样的。
