Z2FSK6-2-1X/2QV力士乐单向阀 

结构原理

1）MK型单向节流阀 该阀是管式联接的单向节流阀，其节流口采用轴向三角槽式结构。旋转调节螺母3，可改变节流口通流面积的大小，以调节流量。正向流动时起节流阀作用；反向流动时起单向阀作用，这时由于有部分油液可在环形缝隙中流动，可以清除节流口上的沉积物。在阀体2左端有刻度槽，调节螺母3上有刻度，用以标志调节流量的大小。

2）F型准确节流阀 该阀主要由阀体1，调节件2和节流套3组成。在节流口4处实现对从A到B的流动的节流。转动节流杆5，可调节节流断面。由于节流口制成薄壁孔，故节流不易受温度的影响。

节流口堵塞原因：

1、油液中的机械杂质或因氧化析出的胶质、沥青、碳渣等污物堆积在节流缝隙处。

2、由于油液老化或受到挤压后产生带电的较化分子，而节流缝隙的金属表面上存在电位差，故较化分子被吸附到缝隙表面，形成牢固的边界吸附层，吸附层厚度一般为5~8微米，因而影响了节流缝隙的大小。以上堆积、吸附物增长到一定厚度时，会被液流冲刷掉，随后又重新附在阀口上。这样周而复始，就形成了流量的脉动。

3、阀口压差较大时，因阀口温度高，液体受挤压的程度增强，金属表面也更易受摩擦作用而形成电位差，因此压差大时容易产生堵塞现象。

减轻节流口堵塞的措施：

1、选择水力半径大的薄刃节流口。

2、准确过滤并定期更换油液。

3、适当减小节流口前后的压差。

4、采用电位差较小的金属材料、选用舒缓反应稳定性好的油液、减小节流口表面粗糙度。

Z2FSK6-2-1X/2QV力士乐单向阀 

Z2FS 型阀是一种采用叠加阀板设计的双单向节流阀。它用于限制一个或两个执行机构油口的主油流量或先导流量。

彼此对称排列的两个单向节流阀可限制一个方向上的流量，同时允许相反方向上的自由回流。

如果是供油节流，则液压油将通过由阀座 (2) 和节流阀芯 (3) 形成的节流点 (1)，经通道 A? 导入执行机构 A?。节流阀芯 (3) 可通过调节螺钉 (4) 进行轴向调节，从而允许调节节流点 (1)。

从执行机构 A? 流回的液压油沿着节流阀芯 (3) 的方向相对弹簧 (5) 移动阀座 (2)，从而使液压油通过单向阀不受阻碍地流动。根据安装位置，节流效应可能发生在供油或排放中。

主流量限制 （型号“2Q”）

要调节执行机构的速度（主流量限制），应在方向阀和底板之间安装双单向节流阀。

先导流量限制 （型号“1Q”）

通过先导式方向阀，可使用双单向节流阀来调节切换时间（先导流量限制）。在这种情况下，该阀安装在先导控制阀和主阀之间。
