LC25DR40E7X插装式减压阀

性能

(1)调压范围：它是指减压阀输出压力P2的可调范围，在此范围内要求达到规定的精度。调压范围主要与调压弹簧的刚度有关。

(2)压力特性：它是指流量g为定值时，因输入压力波动而引起输出压力波动的特性。输出压力波动越小，减压阀的特性越好。输出压力必须低于输入压力—定值才基本上不随输入压力变化而变化。

(3)流量特性：它是指输入压力—定时，输出压力随输出流量g的变化而变化的持性。当流量g发生变化时，输出压力的变化越小越好。一般输出压力越低，它随输出流量的变化波动就越小

减压阀是通过调节，将进口压力减至某一需要的出口压力，并依靠介质本身的能量，使出口压力自动保持稳定的阀门。从流体力学的观点看，减压阀是一个局部阻力可以变化的节流元件，即通过改变节流面积，使流速及流体的动能改变，造成不同的压力损失，从而达到减压的目的。然后依靠控制与调节系统的调节，使阀后压力的波动与弹簧力相平衡，使阀后压力在一定的误差范围内保持恒定。

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。

挖掘机是工程机械主力机种，是建设工程的主要生产工具，因此对挖掘机提出了很高的要求。要求节能低排放、**率、良好的操纵性和降低对环境的负荷等，要实现这些要求必须对挖掘机进行控制，由于液压控制信息处理能力差，不能光靠液压控制主要要靠电子控制。液压动力由液压泵提供，要知道液压泵是挖掘机液压系统的能源装置，将电机的机械能转换为液压能，输出流量和压力，在液压系统中占有非常重要的地位。如果液压泵出现故障，将会影响到整个液压系统的正常工作。
