一种船用电动调节阀 技术领域
本发明涉及调节阀技术领域，具体涉及一种船用电动调节阀。
背景技术
电动调节阀是工业自动化过程控制中的重要执行单元仪表。随着工业领域的自动化程度越来越高，正被越来越多地应用在各种工业生产领域中。与传统的气动调节阀相比具有明显的优点：电动调节阀节能只在工作时才消耗电能，无碳排放更加环保，无需复杂的气动管路和气泵工作站，安装快捷方便。电动调节阀的流量特性，是在阀两端压差保持恒定的条件下，介质流经电动调节阀的相对流量与它的开度之间关系。电动调节阀的流量特性有三种：线性特性、等百分比特性及抛物线特性。电动调节阀一般包括执行器、阀门，阀门的阀杆与执行器相联，通过执行器来控制阀门进行调节，也可根据控制需要，组成智能化网络控制系统，优化控制实现远程监控。工作原理：执行器里面有控制器，控制器把电流信号转换为步进电机的角行程信号，电机转动，由齿轮，杠杆，或者齿轮加杠杆，带动阀杆运作，实现阀芯的直线行程或转动角度行程。
调节阀是过程控制系统中的一个重要环节。过程控制系统由控制对象、测量变送装置、调节器和调节阀组成。调节阀的作用是接收调节器送来的控制信息，调节管道中介质的流量，从而实现过程自动化。
电动调节阀由于具有不需要增加气源液泵、不用敷设管路、调试方便、结构简单等特点，在船舶动力装置中应用广泛，但运行中也存在着诸多问题，比如稳定性差、维修困难、卡阀等问题。
