进口电动蝶阀产品信息：

美国《LAINE》莱恩--进口电动蝶阀，也叫电动控制蝶阀，电控蝶阀，电动法兰蝶阀，电动对夹蝶阀，电动调节蝶阀，是指由角行程的电动执行机构和蝶阀组成，电动执行器驱动蝶阀开启和关闭或者带定位器调节的阀门。连接方式主要有：法兰式和对夹式。是工业自动化控制领域中的重要执行单元。电动蝶阀电动执行器分为普通开关型、无源触点开关型、电位计反馈型、开关控制模拟量输出型、智能调节型。

Lane imported electric butterfly valve, also known as electric control butterfly valve, electric control butterfly valve, electric flange butterfly valve, electric wafer butterfly valve and electric regulating butterfly valve, refers to the valve composed of electric actuator and butterfly valve with angular stroke. The electric actuator drives the butterfly valve to open and close or with positioner adjustment. The connection modes mainly include: flange type and wafer type. It is an important executive unit in the field of industrial automation control. The electric actuator of electric butterfly valve is divided into ordinary switch type, passive contact switch type, potentiometer feedback type, switch control analog output type and intelligent regulation type.

进口电动蝶阀特点:

安装在泵出口时，电动蝶阀同时具有止回阀和闸阀的共同功能，因此可以一阀代两阀，节约安装空间，节省管网造价。

电动启闭，具有任意调整、止回和截止功能。操作方便，安全稳定。

电动蝶阀可连续实现慢开、快开或快关、慢关的动作，并防止了泵出口介质倒流和水锤的产生。

流阻小。本阀全开时流阻系数不超过0.3，因此可以节约能源，降低管路的运行费用。

当发生事故或停电时，可以通过手动操作控制蝶阀启闭。

节能驱动，与普通蝶阀同样的驱动电机即可实现快关段高速小转矩和慢关低段大转矩的功能。

When installed at the pump outlet, the electric butterfly valve has the common function of check valve and gate valve at the same time. Therefore, one valve can replace two valves, saving installation space and pipe network cost.

Electric opening and closing, with arbitrary adjustment, check and cut-off functions. Easy to operate, safe and stable.

The electric butterfly valve can continuously realize the action of slow opening, fast opening, fast closing and slow closing, and prevent the backflow of medium at the pump outlet and the generation of water hammer.

Low flow resistance. When the valve is fully open, the flow resistance coefficient does not exceed 0.3, so it can save energy and reduce the operation cost of the pipeline.

In case of accident or power failure, the opening and closing of butterfly valve can be controlled by manual operation.

Energy saving drive, the same drive motor as ordinary butterfly valve can realize the functions of high-speed small torque in fast closing section and large torque in slow closing low section.
