各类液压阀的共同点与不同点
液压阀是工业生产中Zui为常用的系统,主要用于控制液压系统中的油液的流动方向,还可以 有效地调节压力以及流量。液压阀主要有三种,即压力阀、方向阀和流量阀。对于形状相同 的阀而言,企业可以根据其作用机制的不同而选择不同的功能。虽然液压阀的种类多种多 样,便这些液压阀之间总是有着基本的共同点。
从液压阀的结构上来看,所有的 液压阀都包含有阀体、阀芯以及驱动液压阀芯动作的元部件,这里的元部件主要是指弹簧以 及电磁铁。其实所有液压阀的工作原理就是相同的,他们的开口大小、阀进、出口间压差以 及流过阀的流量都需要符合一定的比例关系,而且各种液压阀可以根据实际需要控制其各自 不同的参数。
液压阀在实际工作中需要满足哪些要求呢?专家指出,液压阀必需 要动作灵敏,而且还要做到使用可靠,工作时要保证较小的冲击以及振动,另外,油液所流 过的压力要保证较少的损失,而且密封性能要好。紧凑的结构是液压阀的Zui基本的要求,而 且维护、安装、调整与使用起来也非常的方便,通用性也要强。
为了保证液压系 统的正常工作,企业平时一定要做好液压内部的清洁,因此在新的设备运行之前一定要保证 液压系统不受污染。但是,使用过程中会造成液压阀内部的污染是不可避免的,这就需要大 家注意元件本身的内部清洁。如果新元件内部含有毛刺、切屑等污染物,那就说明该元件受 到了不良的储存与搬运的影响,这时候就需要对油箱进行充分的清理,必要时还需要采取措 施将污染物取出,以免设备运行会引发安全故障。
液压系统离不开液压阀的存在,质量优良的液压阀可以使液压系统的设计更合理、性能更优良、安装更简便。每个企业在选择液压阀时都应该考虑其额定的压力,同时还要考虑流量、安装形式以及经济性等方面的因素。
在选择液压阀之前,企业应该根据系统的功能要求确定液压阀的类型,然后再根据实际情况选择合理的液压阀连接方式,也可以是管式连接,也可以是板式连接。接下来,大家就需要根据液压系统所设计的Zui高工作压力来确定液压阀的额定压力,然后再根据液压阀的Zui大流量来确定企业所需要的液压阀的流量规格。举例而言,溢流阀应根据液压泵的Zui大流量来选取,而流量阀则要根据回路所控制的流量范围来选取,企业在生产过程中尽量的选择标准系统的通用产品。
以方向阀为例,大家在选择时可以根据系统的工作要求来选择方向阀的种类,例如,如果物体的流动方向为一个方向,那就需要选择单向阀,而如果执行元件需要完成工作循环或者往复运动,那就需要选用可以换向阀来确定油流的方向,也可以接通或者关闭油路。如果要完成两个工作状态,那就需要使用二位换向阀。
接下来我们再来看一下压力阀。压力阀是用于控制液压系统的重要器件,大家可以根据液压系统的工作压力以及压力的实际需求来选取合适的控制阀。在实际的生产过程中,为了防止系统过载,大家可以选择在泵的出口再并联一下安全阀,这样就可以保持整个系统的安全了。大家在选择液压阀时一定要从安全的角度出发,确保生产安全,这才是选择的核心所在。
