蒸汽节能中的阀门是什么？怎么用？

日期： 2023-04-21 作者：晟德亿编辑

阀门是用于打开和关闭管道的管道附件，控制流量，调整和控制输送介质的参数（温度、压力和流量）。根据其功能，可分为关闭阀、止回阀、调节阀等。

阀门是流体输送系统的控制部件，具有截止、调节、导流、防止逆流、稳压、分流或溢流泄压等功能。从简单的截止阀到极其复杂的自动控制系统，流体控制系统的阀门有多种和规格。

阀门可用于控制空气、水、蒸汽、各种腐蚀性介质、泥浆、油、液体金属和放射性介质的流动。根据材料，阀门也分为铸铁阀、铸钢阀、不锈钢阀（201.304.316等）、铬钼钢阀、铬钼钒钢阀、双相钢阀、塑料阀、非标定制阀等。

阀门是控制流体方向、压力和流量的装置。

阀门是管道流体输送系统中的控制部件，用于改变路段和介质的流向，具有导流、截止、节流、停止、分流或溢流、卸载等功能。流体控制阀，从简单的截止阀到极其复杂的自动控制系统，从非常小的仪表阀到10m的工业管道阀。可用于控制水、蒸汽、油、气体、泥浆各种腐蚀性介质，液体金属和放射性流体流动，阀门工作压力可以从0.0013mpa到1000mpa，工作温度可为c-270℃至1430℃。

阀门控制可采用手动、电动、液动、电液、气液动、正齿轮、伞齿轮驱动等多种传统方式。在压力、温度或其他形式的传感信号的作用下，可以根据预定要求或不依赖传感信号进行简单的打开或关闭，阀门可以通过驱动或自动机构提升起重机构。滑动、旋转以改变流道面积，以实现其控制功能。
