佛山贺德克液压阀 电磁溢流阀

贺德克比例减压阀PDM08130-01X-25-G24-Z4;344 属高压阀系列，适用于冶金、石油、液压、水压试验机组上。主要用途:是采用节流耗能达到降压的功能，能使高压、超高压设备和高压管道内的高压水通过此阀将高压水降至低压所需压力后排出，使高压系统压力均匀降低。
工作原理
导阀的开启都是利用顶部的调节螺栓顺时针方向拧动，使弹簧缩产生的弹力，使导阀膜片向下凹陷，作用在导阀连杆上的力，使之向下位移打开导阀。当导阀开启后，上游进汽管段A腔的蒸汽通过α通道(供汽调节通道)，经过导阀进入导阀环形汽腔，由β通道直接送到下面的活塞汽缸上腔。在A腔蒸汽不断的供给下，压力持续升高，推动活塞下行打开主阀，这时蒸汽源源不断从A腔流至B腔。当下游出口管段B腔负荷满足的情况下，余多的蒸汽又使B腔内的压力不断升高。不断升高的压力通过γ通道(压力感应通道)反馈到导阀膜片下腔，使导阀膜片向上突起，克服了上部调节弹簧的压力，导阀被关小或关闭。从而，关小或关闭来自上游α通道的蒸汽源。当活塞汽缸上腔压力下降时，在下面复位弹簧的作用下，主阀被关小或关闭，这时B腔内的压力开始下降，这样周而复始达到调压的目的。3115602;WKM08130C-01-C-N-24DG

贺德克流量节流阀SR08-01-C-N-7.9H;节流阀(Choke valve)的外形结构与截止阀并无区别，只是它们启闭件的形状有所不同。
节流阀的启闭件大多为圆锥流线型，通过它改变通道截面积而达到调节流量和压力。节流阀供在压力降极大的情况下作降低介质压力之用。介质在节流阀瓣和阀座之间流速很大，以致使这些零件表面很快损坏－即所谓气蚀现象。为了尽量减少气蚀影响，阀瓣采用耐气蚀材料（合金钢制造）并制成顶jian角为140～180的流线型圆锥体这还能使阀瓣能有较大的开启高度，一般不推荐在小缝隙下节流。由于节流阀的流量不仅取决于节流口面积的大小，还与节流口前后的压差有关，阀的刚度小，
故只适用于执行元件负载变化很小且速度稳定性要求不高的场合。
对于执行元件负载变化大及对速度稳定性要求高的节流调速系统
，必须对节流阀进行压力补偿来保持节流阀前后压差不变，从而达到流量稳定705787;DRVP-20-01.2;281
