调压步骤
1、关闭减压阀前的闸阀,开启减压阀后的闸阀,制造下游低压环境;
2、将调节螺钉按逆时针旋转至最上位置(相对最低出口压力),然后关闭减压阀后闸阀;
3、慢慢开启减压阀前的闸阀至全开;
4、顺时针慢慢旋转调节螺钉,将出口压力调至所需要的压力(以阀后表压为准);调整好后,将锁紧
螺母锁紧,打开减压阀后闸阀;
5、如在调整时出口压力高于设定压力,须从第一步开始重新调整,即只能从低压向高压调。期正常工作。
使用技巧
在设定机械泵的驱动压力时,正确的方法是使驱动压力高于背压1-1.

减压阀
5kg/cm2(15-20psig)。这在大多数情况下是正确的。但有时为达到泵的要求排量,需要将驱动压力设得稍高一些。驱动压力高时,不利的一面是容易对进气阀造成磨损。如果驱动压力高于要求值,会对进气阀造成严重的磨损而不得不提前更换进气阀。
在这种情况下,建议使用减压阀或减压阀站。减压阀既可以允许将驱动压力维持在能够满足泵排量的设定压力,同时也可以保护进气阀不受磨损。另外,在应用空间较狭窄时,建议使用带集汽管的减压阀站。在泵泵水过程中,集汽管为泵供汽从而为泵提供了缓冲区。这个缓冲区使整个装置的动作柔和,减少对减压阀的磨损。
DB和DBW类型阀是插装结构先导式溢流阀 ,它们用于限制系统压力(DB)或限制和 电磁卸载(DBW只带螺纹连接
)系统压力。 该阀组主要包括阀体和溢流阀插装元件。管路中的压力作用于阀芯,并经过节流孔同时作用于球
阀芯。当管路中的压力超过弹簧设定的压力值时,球阀芯克服弹簧力开启。此时来自油口的油液经节流孔流入弹
簧腔,并通过控制通道由外部引回油箱。由于在阀芯高压流体流动的平衡状态,油液经A口流向B口,同时保持设
定的工作压力不变。DBW 型溢流阀(仅螺纹连接型)原则上功能与DB型相同。借助顶装方向阀可控制主阀卸荷。
