液压系统顺序阀与溢流阀区别
液压系统顺序阀和溢流阀的区别。
液压系统中顺序阀与溢流阀相仿,爲使执行元件准确实现顺序动作,要求调压偏差小。爲此,应减小调压弹簧的刚度。其与溢流阀的区别在于它通过阀门的阻力损失接近于零。
(1)内控式直动顺序阀与直动式溢流阀的区别
内控式直动顺序阀的工作原理与直动式溢流阀相似,区别在于:二次油路即出口压力油不接回油箱,因而洩漏油口必须单独接回油箱,爲减少调压弹簧刚度,设置了控制柱塞。
内控式顺序阀在其进油路压力达到阀的设定压力之前,阀口一直都是关闭的,达到设定压力后,阀口才开啓,使压力油进入二次油路,去驱动另一执行元件。
(2)卸荷溢流阀与外控顺序阀作卸荷阀的区别
卸荷溢流阀主要用于液压系统装有蓄能器的液压回路中,当蓄能器充液压力达到卸荷溢流阀的设定压力时,它自动使液压泵卸荷。卸荷溢流阀内装单向阀,用来防止蓄能器中的压力油倒流。此时,由蓄能器向系统供油并保持压力。当蓄能器中油液压力降到卸荷溢流阀的设定压力时,卸荷溢流阀关闭,液压泵恢複向蓄能器充液。液压蓄能器增速回路,就是因爲在该回路中,应该选用卸荷溢流阀作卸荷阀,而选用了一般外控顺序阀作卸荷阀,从而导緻液压泵出口压力时高时低,造成回路功耗大、油温高,液压系统不能正常工作。
顺序阀职能符号与溢流阀和减压阀的区别如图5所示。
