DB20-2-50/50力士乐溢流阀
溢流阀一般有两种结构:1、直动型溢流阀 。2、先导式溢流阀。
对溢流阀的主要要求:调压范围大,调压偏差小,压力振摆小,动作灵敏,过载能力大,噪声小。
先导型溢流阀的导阀部分结构尺寸较小,调压弹簧不必很强,因此压力调整比较轻便。但因先导型溢流阀要在先导阀和主阀都动作后才能起控制作用,因此反应不如直动型溢流阀灵敏。
与三节同心结构相比,二节同心结构的特点是:①主阀芯仅与阀套和主阀座有同心度要求,免去了与阀盖的配合,故结构简单,加工和装配方便。②过流面积大,在相同流量的情况下,主阀开启高度小;或者在相同开启高度的情况下,其通流能力大,因此,可做得体积小、重量轻。③主阀芯与阀套可以通用化,便于筹备批量生产。
液压阀是用来控制液压系统中油液的压力、流量和液体流动方向。
二、液压阀的分类
按功能分:
方向控制阀(单向阀、换向阀)
压力控制阀(溢流阀、减压阀、顺序阀、压力继电器)
流量控制阀(节流阀、调速阀)
按操纵方式分:
手动和脚踏、机动、电动、液动、电液动等。
共同点
(1) 在结构上,所有的阀都有阀体、阀芯(转阀或滑阀)和驱使阀芯动作的部件(如弹簧、电磁铁)组成。
(2)在工作原理上,所有阀的开口大小,阀进、出口压差以及流过阀的流量之间的关系都符合孔口流量公式,仅是各种阀控制的参数各不相同而已。
三、对液压阀的基本要求
(1)动作灵敏,使用可靠,工作时冲击和振动小。
(2)油液流过的压力损失小。
(3)密封性能好。
(4)结构紧凑,安装、调整、使用、维护方便,通用性大。
DB20-2-50/50力士乐溢流阀
DB 型阀是先导控制式的溢流阀; DBW 型阀是先导控制式的电磁溢阀。 DB
型阀是用来控制液压系统的压力; DBW 型阀也可以控制液压系统的压力, 并且
能在任意时刻使系统卸荷。
DB 型阀主要是由先导阀和主阀组成。 DBW 型阀是由电磁换向阀、 先导阀和
主阀组成。
DB 型溢流阀:
A 腔的压力油作用在主阀芯下端的同时,
通过阻尼器 、 和通道 、 、
作用在主阀芯上端和先导阀 的锥 阀
上。 当系统压力超过弹簧 的调定值时, 锥阀
被打开。 同时主阀芯上端的压力油通过阻尼
器 、 通道 、 弹簧腔 及通道
流回 B 腔(控制油内排型) 或通过外排口
流回油箱(控制油外排型) 。 这样, 当压力油通过阻尼器 、 时在主阀
芯 上产生了一个压力差, 主阀芯在这个压差的作用下打开, 这样在调定的
工作压力下压力油从 A 腔流到 B 腔(即卸荷) 。

二通插装阀以其独特的优点以及经济和技术上的明显优势被广泛应用到各个行业。在集成的液压元件中,当通径小于32mm时,可采用叠加
阀,当通径大于中32mm时,应考虑采用插装阀。在一个液压系统中,可根据需要,液压控制阀全部采用二通插装阀;也可以部分液压控制阀采用滑阀式,另一部分液压控制阀采用二通插装阀,充分发挥两种液压控制阀各自的优点。
压力机械属于重型机械,主要应用于冶金行业.重型机械制造、化工等行业,如冲压机、锻造机、剪切机、粉末制品压力机、挤压机等。压力机械的动力及控制部分多数采用液压传动,由于液压系统所需的压力高、流量大,故适于用二通插装阀来控制液压系统的压力、流量和流动方向。
