图文讲解液压系统溢流阀分类与工作原理
液压系统的溢流阀按照结构不同,溢流阀可分爲直动式和先导式两种。先导式溢流阀与电磁换向阀複合可构成电磁溢流阀,先导式溢流阀与单向阀複合可构成卸荷溢流阀。下面给大家介绍下液压系统溢流阀的分类以及工作原理。
液压系统分类及详细说明:
直动式溢流阀:
直动式溢流阀有锥阀式、球阀式、滑阀式三种结构。下图爲滑阀式结构的直动式溢流阀的工作原理。
压力油经阻尼孔进入阀芯底部,当作用在阀芯上的作用力大于弹簧力时,阀口打开,使油液溢流。通过转动手轮可以调节弹簧预紧力,从而调节溢流阀的开啓压力,通过更换不同刚度的弹簧可以调整溢流阀的调压范围。直动式溢流阀结构简单,灵敏度高,但不适于在高压大流量的场合。
下图爲溢流阀的剖面图,原理与上图相同。
先导式溢流阀:
在中高压和大流量场合中,一般采用先导式溢流阀,包含先导阀和主阀两部分。下图爲先导式溢流阀的工作原理。
如上图所示,上端爲先导阀,下端爲主阀,压力油经阻尼孔进入主阀上腔和先导阀右腔。压力不高时,主阀上下两腔压力相等,在弹簧力作用下,先导阀和主阀都爲关闭状态;当压力升高到可以打开先导阀芯时,油液经阻尼孔在主阀上下两腔産生压差,将主阀芯推开,油液溢流。在先导阀右端有个遥控口,可以接二位换向阀控制溢流阀是否卸荷,也可以接个调定压力较小的溢流阀进行远程调压。通过调节先导阀弹簧的预紧力可调节溢流阀的调定压力,而主阀的弹簧刚度较小,隻起複位主阀芯的作用。下图爲闆式先导溢流阀的剖面图及其符号。
说明:该阀的先导阀的洩露油爲内洩,x爲遥控口,可以进行远程调压。
电磁溢流阀:
电磁溢流阀是在先导溢流阀的基础上加二位电磁换向阀,通过控制先导阀的控制油路是否通油箱,以实现液压系统的卸荷和加载。下图爲电磁溢流阀的应用场合。电磁阀不得电时,溢流阀发挥作用;当电磁阀得电时,系统卸荷。
卸荷溢流阀:
卸荷溢流阀又称爲单向溢流阀,下图爲卸荷溢流阀的结构和职能符号。当系统压力不高时,单向阀打开,泵向系统供油;当压力升高,溢流阀开啓溢流,系统卸荷,此时单向阀关闭。卸荷溢流阀可以实现系统的自动加载和卸荷,常与蓄能器配合使用。
以上就是液压系统溢流阀的详细分类及说明,提醒大家,需要特别注意的是,液压系统中容易産生噪声的元件一般认爲是泵和阀,阀中又以溢流阀和电磁换向阀等爲主。
