電動蝶閥的常用規(guī)格涵蓋了多個方面，包括公稱通徑、閥體材料、控制信號、管路連接方式、力矩等關(guān)鍵參數(shù)。以下是對電動蝶閥常用規(guī)格的詳細(xì)歸納：

　　The common specifications of electric butterfly valves cover multiple aspects, including nominal diameter, valve body material, control signal, pipeline connection method, torque and other key parameters. The following is a detailed summary of commonly used specifications for electric butterfly valves:

　　一、公稱通徑

　　1、 Nominal diameter

　　電動蝶閥的公稱通徑范圍較廣，常見的規(guī)格有DN50至DN600，也有部分產(chǎn)品可達(dá)到更大的通徑。具體選擇時，需根據(jù)管道系統(tǒng)的實(shí)際需求來確定。

　　The nominal diameter range of electric butterfly valves is relatively wide, with common specifications ranging from DN50 to DN600, and some products can achieve larger diameters. The specific selection needs to be determined based on the actual requirements of the pipeline system.

　　二、閥體材料

　　2、 Valve body material

　　閥體材料的選擇對于電動蝶閥的性能和使用壽命至關(guān)重要。常見的閥體材料包括灰鑄鐵（適用于DN50至DN150的較小通徑）、球墨鑄鐵（適用于DN200至DN600的較大通徑）以及不銹鋼等。不銹鋼材料具有優(yōu)異的耐腐蝕性和耐高溫性能，適用于對介質(zhì)有特殊要求或工作環(huán)境惡劣的場合。

　　The selection of valve body material is crucial for the performance and service life of electric butterfly valves. Common valve body materials include gray cast iron (suitable for smaller diameters from DN50 to DN150), ductile iron (suitable for larger diameters from DN200 to DN600), and stainless steel. Stainless steel material has excellent corrosion resistance and high temperature resistance, and is suitable for occasions with special requirements for media or harsh working environments.

　　三、控制信號

　　3、 Control signal

　　電動蝶閥通常接受標(biāo)準(zhǔn)的控制信號來實(shí)現(xiàn)開關(guān)或調(diào)節(jié)功能。常見的控制信號包括0-10vDC、4-20mA等模擬信號，以及開關(guān)量信號。這些信號可以通過電動執(zhí)行器接收并轉(zhuǎn)換為閥門的動作指令。

　　Electric butterfly valves usually accept standard control signals to achieve switching or regulating functions. Common control signals include analog signals such as 0-10vDC and 4-20mA, as well as switch signals. These signals can be received by electric actuators and converted into valve action commands.

　　四、管路連接方式

　　4、 Pipeline connection method

　　電動蝶閥的管路連接方式多樣，常見的包括法蘭連接和對夾式連接。法蘭連接適用于需要較高密封性能和承壓能力的場合，而對夾式連接則更加簡便快捷，適用于對安裝空間有要求的場合。

　　There are various pipeline connection methods for electric butterfly valves, including flange connections and clamp connections. Flange connections are suitable for situations that require high sealing performance and pressure bearing capacity, while clamp connections are more convenient and efficient, suitable for situations that require installation space.

　　五、力矩

　　5、 Torque

　　電動蝶閥的力矩是指執(zhí)行器驅(qū)動閥門動作時所需的扭矩大小。力矩的大小與閥門的尺寸、介質(zhì)壓力以及密封面的摩擦力等因素有關(guān)。常見的力矩范圍從50N.M至4000N.M不等，具體選擇時需根據(jù)閥門的實(shí)際需求和執(zhí)行器的性能來確定。

　　The torque of an electric butterfly valve refers to the amount of torque required for the actuator to drive the valve action. The magnitude of torque is related to factors such as valve size, medium pressure, and frictional force on the sealing surface. The common torque range is from 50N M to 4000N M varies, and the specific selection needs to be determined based on the actual requirements of the valve and the performance of the actuator.

　　六、其他常用規(guī)格

　　6、 Other commonly used specifications

　　除了上述關(guān)鍵參數(shù)外，電動蝶閥的常用規(guī)格還包括工作壓力、介質(zhì)溫度、流量特性等。工作壓力通常根據(jù)管道系統(tǒng)的實(shí)際需求來確定，介質(zhì)溫度則需考慮閥門的材質(zhì)和密封材料的耐溫性能。流量特性則決定了閥門在調(diào)節(jié)介質(zhì)流量時的性能表現(xiàn)。

　　In addition to the key parameters mentioned above, common specifications for electric butterfly valves also include working pressure, medium temperature, flow characteristics, etc. The working pressure is usually determined based on the actual needs of the pipeline system, while the medium temperature needs to consider the temperature resistance of the valve material and sealing material. The flow characteristics determine the performance of the valve in regulating the flow rate of the medium.

　　綜上所述，電動蝶閥的常用規(guī)格涵蓋了多個方面，具體選擇時需根據(jù)管道系統(tǒng)的實(shí)際需求、工作環(huán)境以及介質(zhì)特性等因素進(jìn)行綜合考慮。在選擇時，建議咨詢專業(yè)的閥門制造商或供應(yīng)商，以確保所選產(chǎn)品符合實(shí)際需求并具有優(yōu)異的性能表現(xiàn)。

　　In summary, the common specifications of electric butterfly valves cover multiple aspects, and the specific selection needs to be comprehensively considered based on factors such as the actual needs of the pipeline system, working environment, and medium characteristics. When choosing, it is recommended to consult a professional valve manufacturer or supplier to ensure that the selected product meets actual needs and has excellent performance.
