How to Achieve Valve Automation Through the Use of Control Tops

全部阀s在一个过程中，工厂包含所谓的阀门执行器, which are simply the valve mechanisms that actually open and close the valves. Simple valves that are opened and closed manually typically use a lever or a wheel to operate the valve.

但是，具有大量阀门的大多数工艺厂具有用于打开和关闭阀的自动阀致动器。该阀门自动化通过空气压力，液压或电子方式操作。自动阀门执行器通常在制药制造厂和食品和饮料加工行业的过程植物中找到。

这y are typically used to controlbutterfly valves,seat valves， 和lol滚球 雷竞技 在含有大量阀门的过程管道中。

在加工管道安装中，包含大量自动阀门，在阀门执行器上安装控制顶部可以提供许多优点。

• 这y notify the pipeline operator if each and every valve in their system is operating properly, and set to the correct position for the intended operation.
• Automation provides significant cost savings. For example, without a control top a PLC may think that a particular valve is open when it actually isn’t. As a result,价值数千美元的产品可能会意外地送到废物排水或污染大型储存筒仓。

由于控制顶部所提供的和平，大多数大型过程管道系统运营商将支付额外成本以在其自动阀门执行器上安装控制顶部作为风险缓解措施。

ThinkTop™ V50 & V70

这ThinkTop™ V50 and V70 control tops来自CSI供应商Alfa Laval设计用于该公司的隔膜，蝴蝶，单座椅和混合阀。雷电竞它们常用于乳制品,food,beverage， 和biopharmaceutical制造业。

Sleek and compact, the ThinkTop’s control unit uses a single sensor that may be fitted with up to three solenoids. Inside the ThinkTop’s head, this sensor detects the valve stem movement and valve position to an accuracy of +/- 0.004 inches.

Thinktop单元使用安装在阀门执行器的杆上的物理传感器目标来转换PLC的电气输出来激励或断电空气电磁阀。然后，处理管道中的每个阀的精确阀位置基本上由在每个阀门执行器上的Thinktop控制顶部提供的详细信息管理。

ThinkTop control units are intuitive, reliable, and quick to set up。这自动设置和实时设置功能设计入thanktop基于其DNA型材识别阀门类型，并且可以在没有任何操作员干预的情况下完成阀门设置。

Bürkert Control and Communication

For certain types of requirements, there’s another variant of an automated control top that’s known as a阀门定位器。Valve positioners are used to control valves that may need to be partially opened, and not actuated into either the fully open or fully closed positions.

这se applications can include valve actuators used with certain steam-based processes, valves used for the mixing of hot and cold liquid media to a precise temperature (i.e., a thermostatic mixing valve), and some sanitary valve applications used for reducing pressure in process pipelines.

For the precise control of throttling and regulating valves that may be operated in a partially opened position, CSI offers a line of specialized control top valve positioners manufactured byBürkert控制和通信。Burkert的阀门定位器型号的范围从简单的橱柜安装的封装到时尚，公共汽车兼容装置，具有背光显示和直观的编程。
