同时由于间隙1～3处水垢的生成,降低了轴套及动、静环密封面的表面粗糙度,也会促进密封面的磨损,造成机械密封出现泄漏。水垢的进一步增加使间隙2～3处更加减小,使冷却水传热效率进一步下降。当水垢在静环波纹管内圆和水套外圆处堆集并堵死静环环座与水套的径向间隙时,将产生以下两个结果:石墨静环的密封面磨损后,波纹管的弹力与部分不平衡力之和克服不了水垢对静环座的摩擦阻力,静环不能向密封面补偿,必将出现比较严重的泄漏。

失调阀归于调理阀范围，它的任务原理是经过改观阀芯与阀座的间隙（即开度），改观流体走过阀门的呆滞屏障，到达调理流量的手段。失调阀相等于一个全部屏障能够改观的节食部件，对于没有可紧缩流体，由流量方程式可得。Kv为失调阀的阀门系数。它的界说是：当失调阀始终差压为1bar（约1kgf/cm2）时，走过失调阀的流量值（m3/h）。失调阀全开时的阀门系数相等于一般阀门的呆滞威力。假如失调阀开度没有变，则阀门系数Kv没有变，也就是说阀门系数Kv由开度而定。

涂覆阀门电动装置是实现阀门程控、自控和遥控不可缺少的设备，它在运动过程中可由行程、转矩或轴向推力的大小来控制。由于阀门电动装置的工作特性和利用率取决于阀门的种类、装置工作规范及阀门在管线或设备上的位置，正确如何选择阀门电动装置，对防止出现超负荷现象至关重要。操作推力阀门电动装置的主机结构有两种：一种是不配置推力盘，直接输出力矩;另一种是配置推力盘，输出力矩通过推力盘中的阀杆螺母转换为输出推力。
