The installation and operation methods of the electric butterfly valve

中英合資天蝶閥門生產的蝶閥有各種不同的驅動方式：手柄蝶閥、渦輪蝶閥、電動蝶閥、氣動蝶閥。其中電動蝶閥精度高，省力。現在天蝶閥門給大家介紹一下電動蝶閥的安裝與操作方法。

Sino-British joint venture - Tandy Valve 's butterfly valves are driven in a variety of different ways: handle butterfly valve, turbine butterfly valve, electric butterfly valve, pneumatic butterfly valve .Among them, the electric butterfly valve precision is high, the most labor-saving.Now  Sino-British joint venture - Tandy Valve introduce to you，the installation and operation methods  of the electric butterfly valve.

蝶閥常見到的驅動方式有手動的、氣動的、液動的和電動的。本篇文章主要介紹電動執行器電動蝶閥。電動執行器電動蝶閥又可以細分為手柄蝶閥和渦輪蝶閥。兩者對于電動執行器電動蝶閥的安裝沒有什么大的影響，區別更多的是在于操作使用上面。
The most common driving methods for butterfly valves are manual, pneumatic, hydraulic and electric. This article mainly introduces electric butterfly valves. electric butterfly valve can be subdivided into handle butterfly valve and turbine butterfly valve. Both have little impact on the installation of electric butterfly valves. The difference is more in operational use.

電動執行器電動蝶閥的安裝注意事項
Precautions of the electric butterfly valve installation 

1.電動執行器電動蝶閥在安裝前的準備工作，要先確認產品是否適用于管道中介質的工況，蝶閥的內部必須是干凈的，包括密封圈，閥軸，蝶板上都不能有雜質異物。在沒有對蝶閥做清洗之前，不要關閉蝶板，以防對密封圈造成損傷。
1. Before the installation of the electric butterfly valve, it is necessary to confirm whether the product is suitable for the working condition of the medium in the pipeline. The interior of the butterfly valve must be clean, including the sealing ring, the valve shaft, and the butterfly plate. Do not close the disc before cleaning the butterfly valve to prevent damage to the seal.

2.對夾式的電動執行器電動蝶閥在安裝時需要使用蝶閥法蘭。
2. The clip-on electric butterfly valve requires the use of a special butterfly valve flange.

3.在管道上應該立裝，不能倒著裝。
3. It is better to stand upright on the pipeline and not to reverse it.

4.當需要做調節流量用時，推薦使用渦輪蝶閥。
4. When it is necessary to adjust the flow, it is recommended to use a turbine butterfly valve.

5.安裝之后，使用過程中要定期對閥門每一處部件進行檢查，發現故障及時排除。
5. After installation, check every part of the valve periodically during the use process and remove any faults.

電動執行器電動蝶閥的操作方法
The operation methods of the electric butterfly valve

從上面我們知道蝶閥分為手動蝶閥和電動蝶閥，他們的操作方法當然也會有所區別。手柄蝶閥的操作是，扳動手柄，逆時針旋轉打開閥門，順時針旋轉則閥門關閉。渦輪蝶閥是在蝶閥的閥桿上加裝一個蝸輪減速器。渦輪裝置讓蝶閥的操作更加省力，應對更大的介質壓力環境，同時還能對閥門的操作性做出改善。
From the above we know that electric butterfly valves are divided into handle butterfly valves and turbine butterfly valves. Their operation methods will of course be different. The operation of the handle butterfly valve is to pull the handle, turn it counterclockwise to open the valve, and turn it clockwise to close the valve. The turbine butterfly valve is equipped with a worm gear reducer on the stem of the butterfly valve. The turbine device makes the operation of the butterfly valve more labor-saving and can cope with a larger medium pressure environment while improving the operability of the valve.

蝶閥口徑在150mm以下的，推薦使用手柄驅動，超過150mm口徑，則推薦使用電動執行器，操作起來更加省力。手柄蝶閥大口徑只能做到250mm，超過這個大口徑，就不再適用，需要裝配電動或者氣動執行器。
If the diameter of the butterfly valve is less than 150mm, it is recommended to use the handle to drive. If the diameter of the butterfly valve is more than 150mm, it is recommended to use a turbine device to make it easier to operate. The maximum diameter of the handle butterfly valve can only be 250mm. If it exceeds this maximum diameter, it will no longer be suitable and electric or pneumatic actuators will be required.

在工業工程中，我們推薦使用電動蝶閥，因為除了省力外，電動蝶閥的密封性要好過手柄蝶閥。還要一點，在開關頻率較高的工況管道中，電動蝶閥的使用壽命高于手柄蝶閥。
In industrial engineering, we recommend the use of a turbine butterfly valve, because in addition to effort, the turbine butterfly valve is better than the handle butterfly valve. In addition, the life of the turbine butterfly valve is higher than that of the handle butterfly valve in the pipeline with high switching frequency.
