数控剪板机具备自我诊断功能，更能方便客户操作

　　数控剪板机液压阀原理集流阀作用与分流阀相反，使流入集流阀的流量按比例分配。调速阀在载荷压力变化时能保持节流阀的进出口压差为定值。这样，在节流口面积调定以后，不论载荷压力如何变化，调速阀都能保持通过节流阀的流量不变，从而使执行元件的运动速度稳定。分流集流阀兼具分流阀和集流阀两种功能。
　　（1）溢流阀：能控制液压系统在达到调定压力时保持恒定状态。用于过载保护的溢流阀称为安全阀。当系统发生故障，压力升高到可能造成破坏的限定值时，阀口会打开而溢流，以保证系统的安全。
（2）减压(ya)(ya)(ya)(ya)阀(fa)：能(neng)(neng)控(kong)制分支回路(lu)得(de)到比(bi)主回路(lu)油压(ya)(ya)(ya)(ya)低的(de)稳定(ding)(ding)压(ya)(ya)(ya)(ya)力(li)。减压(ya)(ya)(ya)(ya)阀(fa)按它所控(kong)制的(de)压(ya)(ya)(ya)(ya)力(li)功(gong)能(neng)(neng)不同，又(you)可𓄧分为定(din🐬g)(ding)值减压(ya)(ya)(ya)(ya)阀(fa)（输(shu)出压(ya)(ya)(ya)(ya)力(li)为恒定(ding)(ding)值）、定(ding)(ding)差减压(ya)(ya)(ya)(ya)阀(fa)（输(shu)入与输(shu)出压(ya)(ya)(ya)(ya)力(li)差为定(ding)(ding)值）和定(ding)(ding)比(bi)减压(ya)(ya)(ya)(ya)阀(fa)（输(shu)入与输(shu)出压(ya)(ya)(ya)(ya)力(li)间(jian)保持一(yi)定(ding)(ding)的(de)比(bi)例）。
