节流阀按通道方式可分为直通式和角式两种；按启闭件的形状分，有针形、沟形和窗形三种。节流阀的安装与维护应注意以下事项：
该阀经常需要操作，因此应安装在易于方面便操作的位置上。
安装时要注意介质方向与阀体所标箭头方向保持一致。
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极化分子，而节流缝隙的金属表面上存在电位差，故极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、精密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、选用抗氧化稳定性好的油液、减小节流口表面粗糙度。
