描述
1.智能阀门定位器（核心推测）
核心功能：
阀门位置控制：通过接收4-20mA或数字信号（如HART、Profibus-PA），精确控制阀门开度（精度±0.5%），支持线性、等百分比、快开等流量特性。
自诊断与维护：集成传感器监测阀门行程、气源压力、执行器状态，实时反馈故障代码（如气源不足、机械卡滞），支持预测性维护。
通信接口：支持HART、Foundation Fieldbus、Profibus-DP/PA等工业协议，可与DCS、PLC系统无缝集成。
防爆设计：若”BE”中”E”指防爆，可能通过ATEX、IECEx认证，适用于化工、油气等爆炸性环境。
典型应用：
石油天然气管道调节阀控制。
化工装置反应釜温度/压力调节。
电力锅炉给水阀自动化。
2.阀门控制器扩展模块
核心功能：
信号转换与隔离：将4-20mA信号转换为气动信号（如3-15psi），驱动气动执行器；或实现电气隔离，提高系统抗干扰能力。
多阀门协同控制：支持2-4台阀门联动控制（依”724″中”4″推测），适用于复杂流程工业（如精馏塔温度分层控制）。
本地/远程切换：通过面板按钮或通信指令切换控制模式，适应调试与运行场景。
典型应用：
多阀组控制（如污水处理厂加药系统）。
旧有阀门系统升级（保留原有执行器，仅更换控制模块）。
1.Smart Valve Positioner(Core Speculation)
Core Functions:
Valve Position Control:Precisely controls valve opening(±0.5%)by receiving 4-20mA or digital signals(such as HART and Profibus-PA),supporting flow characteristics such as linear,equal percentage,and quick opening.
Self-Diagnostics and Maintenance:Integrated sensors monitor valve travel,air supply pressure,and actuator status,providing real-time feedback on fault codes(such as air supply shortage and mechanical jams)to support predictive maintenance.
Communication Interface:Supports industrial protocols such as HART,Foundation Fieldbus,and Profibus-DP/PA,enabling seamless integration with DCS and PLC systems.
Explosion-Proof Design:If the”E”in”BE”indicates explosion-proof,the product may be ATEX or IECEx certified,making it suitable for explosive environments such as chemical,oil and gas industries.
Typical Applications:
Oil and gas pipeline regulating valve control.
Chemical plant reactor temperature/pressure regulation.
Power boiler feedwater valve automation.2.Valve Controller Expansion Module
Core Functions:
Signal Conversion and Isolation:Converts 4-20mA signals into pneumatic signals(e.g.,3-15psi)to drive pneumatic actuators;or provides electrical isolation to improve system anti-interference capabilities.
Multi-Valve Collaborative Control:Supports coordinated control of 2-4 valves(based on the”4″in”724″),suitable for complex process industries(e.g.,temperature stratification control of distillation towers).
Local/Remote Switching:Switches control modes via panel buttons or communication commands,adapting to debugging and operation scenarios.
Typical Applications:
Multi-valve manifold control(e.g.,dosing systems in sewage treatment plants).
Upgrading legacy valve systems(retaining the existing actuators and replacing only the control modules).
