Introduction to Explosion-proof electric butterfly valve

中英合資天蝶閥門向大家介紹如下幾款性價比*的電動蝶閥，并帶大家了解一下其運輸注意事項。

The Sino-British joint venture Tandy Valve would like to introduce the following several cost-effective electric butterfly valves,and take you to know its transport matters.

防爆型蝶閥電動執行器，是工業自動化控制領域中的重要執行單元。
Explosion-proof electric butterfly valve is an important execution unit in the field of industrial automation control.

防爆型蝶閥電動執行器連接方式主要有法蘭式和對夾式。

Explosion-proof electric butterfly valve connection methods are mainly divided into flange type and wafer type.

1、蝶閥電動執行器具有結構簡單、體積小、重量輕、材料耗用省，安裝尺寸小，開關迅速、90°往復回轉，驅動力矩小等特點，用于截斷、接通、調節管路中的介質，具有良好的流體控制特性和關閉密封性能。

1. The electric butterfly valve has the characteristics of simple structure, small size, light weight, low material consumption, small installation size, rapid switch, 90° reciprocal rotation, small drive torque, etc. It is used to cut off, connect, adjust the medium in the pipeline. It has good fluid control characteristics and closing and sealing performance.

2、蝶閥電動執行器可以運送泥漿，在管道口積存液體少。低壓下，可以實現良好的密封。 調節性能好。 

2. The electric butterfly valve can transport mud, and it will accumulate least liquid in the pipeline mouth. Under low pressure，it can achieve good seal. It also has good adjustment performance.

3、蝶閥電動執行器蝶板的流線形設計，使流體阻力損失小，可謂是一種節能型產品。

3. The streamlined design of the butterfly plate on electric butterfly valve can reduce the loss of fluid resistance, which is an energy-saving product.

4、蝶閥電動執行器閥桿為通桿結構，經過調質處理，有良好的綜合力學性能和抗腐蝕性，抗擦傷性。蝶閥電動執行器啟閉時閥桿只作旋轉運動而不作升降運行，閥桿的填料不易破壞，密封可靠。與蝶板錐銷固定，外伸端為防沖出型設計，以免在閥桿與蝶板連接處意外斷裂時閥桿崩出。

4. The electric butterfly valve stem is a through-rod structure. After quenching and tempering, it has good comprehensive mechanical properties, corrosion resistance and scratch resistance. When the electric butterfly valve is opened and closed, the valve stem only performs a rotary motion and does not perform lifting operation. The packing of the valve stem is hard to damage, and the seal is reliable. The utility model is fixed with a butterfly taper pin, and the outstretched end is of an anti-bump type design, so as to prevent the valve stem from collapsing when the stem and the disc plate are accidentally broken.

5、蝶閥電動執行器連接方式有法蘭連接、對夾連接、對焊連接及凸耳對夾連接。驅動形式有手動、蝸輪傳動、電動、氣動、液動、電液聯動等執行機構，可實現遠距離控制和自動化操作。

5. Connection modes of the electric butterfly valve are flange connection, clamp connection, butt welding and lug connection. The drive forms include manual, worm wheel drive, electric, pneumatic, hydraulic, electrohydraulic linkage and other actuators, which can realize remote control and automatic operation.

蝶閥電動執行器包裝運輸注意事項：

Noticeable tips to the packaging and transportation of electric butterfly valves: 

1.蝶閥電動執行器兩側應設輕質堵板固封。 
1.Light blocking plates should be installed on both sides of the electric butterfly valve.
2.中、小口徑蝶閥電動執行器應以草繩捆扎，并以集裝箱方式運輸為宜。
2.The medium and small diameter electric butterfly valves should be bundled with straw ropes and transported in containers.
3.大口徑閥門亦有簡易木條框架固體包裝，以免運輸過程中碰損。
3.The large-diameter valve also should have a simple wooden frame for solid packing to avoid damage during transportation.
4.電動調節蝶閥,調節流量和截斷流體的適合裝置。
4.Electric adjustable butterfly valve is the best device for adjusting flow and cutting fluid.
