智能阀门的控制模式是其实现精准调节与高效运行的核心，不同模式根据应用场景的需求，展现出各异的功能特性。这些模式通过集成传感器、执行器和控制算法，让阀门摆脱传统手动操作的局限，实现自动化、智能化的运行管理。

　　The control mode of intelligent valves is the core of achieving precise regulation and efficient operation. Different modes exhibit different functional characteristics according to the needs of application scenarios. These modes integrate sensors, actuators, and control algorithms to free valves from the limitations of traditional manual operation and achieve automated and intelligent operation management.

　　手动控制模式是智能阀门的基础功能，即使在智能化系统中，也保留了手动操作接口。当系统出现故障或需要紧急干预时，操作人员可通过现场旋钮、手柄或远程手动指令直接控制阀门的开关或开度。这种模式为设备运行提供了安全冗余，确保在特殊情况下仍能维持基本操作，尤其适用于对可靠性要求极高的场景。

　　Manual control mode is the basic function of intelligent valves, and even in intelligent systems, manual operation interfaces are retained. When the system malfunctions or requires emergency intervention, operators can directly control the opening or closing of valves through on-site knobs, handles, or remote manual commands. This mode provides safety redundancy for device operation, ensuring that basic operations can still be maintained in special circumstances, especially suitable for scenarios with extremely high reliability requirements.

　　自动控制模式是智能阀门的核心应用模式，其通过接收外部信号实现自主调节。常见的自动控制包括比例控制和 PID 控制：比例控制根据输入信号与设定值的偏差，按固定比例调整阀门开度，适用于负荷变化平缓的场合；PID 控制则通过比例、积分、微分三个环节的协同作用，动态修正偏差，能快速响应参数波动，在温度、压力、流量等需要高精度控制的系统中广泛应用。例如，在供水系统中，智能阀门可根据管道压力传感器的实时数据，自动调节开度以稳定管网压力。

　　Automatic control mode is the core application mode of intelligent valves, which achieves autonomous adjustment by receiving external signals. Common automatic controls include proportional control and PID control: proportional control adjusts the valve opening according to a fixed ratio based on the deviation between the input signal and the set value, which is suitable for situations with gentle load changes; PID control dynamically corrects deviations through the synergistic effect of proportional, integral, and derivative processes, and can quickly respond to parameter fluctuations. It is widely used in systems that require high-precision control such as temperature, pressure, and flow rate. For example, in the water supply system, smart valves can automatically adjust their opening based on real-time data from pipeline pressure sensors to stabilize pipeline pressure.

　　定时控制模式通过预设时间参数实现阀门的周期性动作。操作人员可设定阀门的开启时间、关闭时间及动作间隔，适用于有规律运行需求的场景。比如在农业灌溉中，智能阀门可按预设的时间段自动开启或关闭，实现定时定量灌溉，既节省人力成本，又能保证灌溉的规律性和均匀性。定时控制模式还可与节假日模式结合，在非工作日自动调整运行策略，进一步提升能源利用效率。

　　The timed control mode achieves periodic action of the valve through preset time parameters. The operator can set the opening time, closing time, and action interval of the valve, which is suitable for scenarios with regular operating requirements. For example, in agricultural irrigation, intelligent valves can automatically open or close according to preset time periods, achieving timed and quantitative irrigation, which not only saves labor costs but also ensures the regularity and uniformity of irrigation. The timed control mode can also be combined with the holiday mode to automatically adjust the operation strategy on non working days, further improving energy utilization efficiency.

　　远程控制模式借助网络通信技术，让操作人员在中控室或移动终端上实现对阀门的远程操作与监控。通过物联网平台，操作人员可实时查看阀门的运行状态、开度、压力等参数，并根据需要发送控制指令。这种模式打破了空间限制，尤其适用于分散式布置的阀门系统，如城市管网、污水处理厂等，能大幅提高管理效率，减少现场巡检的工作量。同时，远程控制模式支持数据记录与分析，为系统优化提供依据。

　　The remote control mode utilizes network communication technology to enable operators to remotely operate and monitor valves from the control room or mobile terminals. Through the Internet of Things platform, operators can view the real-time operation status, opening, pressure and other parameters of valves, and send control instructions as needed. This mode breaks the spatial limitations and is particularly suitable for valve systems arranged in a decentralized manner, such as urban pipelines, sewage treatment plants, etc. It can greatly improve management efficiency and reduce the workload of on-site inspections. Meanwhile, the remote control mode supports data recording and analysis, providing a basis for system optimization.

　　联动控制模式是智能阀门与其他设备协同运行的关键，通过系统集成实现多设备的联动响应。例如，在空调系统中，智能阀门可与温度传感器、风机等设备联动，当室内温度高于设定值时，阀门自动增大开度，同时风机加速运转，快速降低室温；当温度达到设定值后，阀门与风机协同调整至节能运行状态。联动控制模式能实现整个系统的协调优化，避免局部设备单独运行导致的能源浪费，提升整体运行效率。

　　The linkage control mode is the key to the coordinated operation of intelligent valves and other devices, achieving linkage response of multiple devices through system integration. For example, in an air conditioning system, smart valves can be linked with temperature sensors, fans, and other devices. When the indoor temperature exceeds the set value, the valve automatically increases its opening and the fan accelerates to quickly lower the room temperature; When the temperature reaches the set value, the valve and fan cooperate to adjust to the energy-saving operation state. The linkage control mode can achieve coordinated optimization of the entire system, avoid energy waste caused by individual operation of local devices, and improve overall operational efficiency.

　　应急控制模式是保障系统安全的重要机制，当检测到异常情况时，智能阀门会自动触发保护动作。例如，当管道压力超过安全阈值、阀门卡涩或电机过载时，系统会立即发出警报，并控制阀门快速关闭或切换至安全开度，防止事故扩大。应急控制模式的响应速度通常以毫秒级计算，能在短时间内切断危险源头，为设备和人员安全提供有力保障。

　　The emergency control mode is an important mechanism to ensure system safety. When an abnormal situation is detected, the intelligent valve will automatically trigger a protective action. For example, when the pipeline pressure exceeds the safety threshold, the valve becomes stuck, or the motor is overloaded, the system will immediately issue an alarm and control the valve to quickly close or switch to a safe opening to prevent the accident from escalating. The response speed of emergency control mode is usually calculated in milliseconds, which can quickly cut off the source of danger and provide strong protection for equipment and personnel safety.
