阀门专业术语及英文注解

阀门行业术语
强度性能
阀门的强度性能是指阀门承受介质压力的能力。

阀门是承受内压的机械产品，因而必须具有足够的强度和刚度，以保证长期使用而不发生破裂或产生变形。

密封性能
阀门的密封性能是指阀门各密封部位阻止介质泄漏的能力，它是阀门最重要的技术性能指标。

阀门的密封部位有三处：启闭件与阀座两密封面间的接触处；填料与阀杆和填料函的配和处；阀体与阀盖的连接处。

其中前一处的泄漏叫做内漏，也就是通常所说的关不严，它将影响阀门截断介质的能力。

对于截断阀类来说，内漏是不允许的。

后两处的泄漏叫做外漏，即介质从阀内泄漏到阀外。

外漏会造成物料损失，污染环境，严重时还会造成事故。

对于易燃易爆、有毒或有放射的介质，外漏更是不能允许的，因而阀门必须具有可靠的密封性能。

流动介质
介质流过阀门后会产生压力损失（既阀门前后的压力差），也就是阀门对介质的流动有一定的阻力，介质为克服阀门的阻力就要消耗一定的能量。

从节约能源上考虑，设计和制造阀门时，要尽可能降低阀门对流动介质的阻力。

启闭力和启闭力矩
启闭力和启闭力矩是指阀门开启或关闭所必须施加的作用力或力矩。

关闭阀门时，需要使启闭件与发座两密封面间形成一定的密封比压，同时还要克服阀杆与填料之间、阀杆与螺母的螺纹之间、阀杆端部支承处及其他磨擦部位的摩擦力，因而必须施加一定的关闭力和关闭力矩，阀门在启闭过程中，所需要的启闭力和启闭力矩是变化的，其最大值是在关闭的最终瞬时或开启的最初瞬时。

设计和制造阀门时应力求降低其关闭力和关闭力矩。

启闭速度
启闭速度是用阀门完成一次开启或关闭动作所需的时间来表示。

一般对阀门的启闭速度无严格要求，但有些工况对启闭速度有特殊要求，如有的要求迅速开启或关闭，以防发生事故，有的要求缓慢关闭，以防产生水击等，这在选用阀门类型时应加以考虑。

动作灵敏度和可靠性
这是指阀门对于介质参数变化，做出相应反应的敏感程度。

对于节流阀、减压阀、调节阀等用来调节介质参数的阀门以及安全阀、疏水阀等具有特定功能的阀门来说，其功能灵敏度与可靠性是十分重要的技术性能指标。

使用寿命
它表示阀门的耐用程度，是阀门的重要性能指标，并具有很大的经济意义。

通常以能保证密封要求的启闭次数来表示，也可以用使用时间来表示。
