压力控制阀有液压和气压两种,但原理几乎一样。
这里说一下液压的 阀门结构:
1—调节螺杆;2—阀体;3—调压弹簧;4—偏流盘;
5—锥阀;6—阻尼活塞 作用 阻尼活塞作用一是在锥阀开启或闭合时起阻尼作用
,用来提高阀的调压稳定性;二是对锥阀起导向作用,
以提高阀的密封性能。 偏流盘的作用:偏流盘上开有环形槽,
用以改变锥阀出油口的液流方向。于是偏流盘受到了一个液动力,
此液动力与弹簧力的作用方向相反,并随溢流量的增加而加大。
当溢流量增加时,由于锥阀开口增大,引起弹簧力增加。
但由于液动力也同时增加,结构抵消了弹簧力的增量。
因此这种阀的进口压力不受流量变化的影响,其p-Q特性曲线比较理想,
启闭特性好,有利于提高阀的额定流量。
