Introduction to Explosion-proof electric butterfly valve

中英合资天蝶阀门向大家介绍如下几款性价比*的电动蝶阀，并带大家了解一下其运输注意事项。

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.

防爆型蝶阀电动执行器，是工业自动化控制领域中的重要执行单元。
Explosion-proof electric butterfly valve is an important execution unit in the field of industrial automation control.

防爆型蝶阀电动执行器连接方式主要有法兰式和对夹式。

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

1、蝶阀电动执行器具有结构简单、体积小、重量轻、材料耗用省，安装尺寸小，开关迅速、90°往复回转，驱动力矩小等特点，用于截断、接通、调节管路中的介质，具有良好的流体控制特性和关闭密封性能。

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、蝶阀电动执行器可以运送泥浆，在管道口积存液体少。低压下，可以实现良好的密封。 调节性能好。 

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、蝶阀电动执行器蝶板的流线形设计，使流体阻力损失小，可谓是一种节能型产品。

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、蝶阀电动执行器阀杆为通杆结构，经过调质处理，有良好的综合力学性能和抗腐蚀性，抗擦伤性。蝶阀电动执行器启闭时阀杆只作旋转运动而不作升降运行，阀杆的填料不易破坏，密封可靠。与蝶板锥销固定，外伸端为防冲出型设计，以免在阀杆与蝶板连接处意外断裂时阀杆崩出。

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、蝶阀电动执行器连接方式有法兰连接、对夹连接、对焊连接及凸耳对夹连接。驱动形式有手动、蜗轮传动、电动、气动、液动、电液联动等执行机构，可实现远距离控制和自动化操作。

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.

蝶阀电动执行器包装运输注意事项：

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

1.蝶阀电动执行器两侧应设轻质堵板固封。 
1.Light blocking plates should be installed on both sides of the electric butterfly valve.
2.中、小口径蝶阀电动执行器应以草绳捆扎，并以集装箱方式运输为宜。
2.The medium and small diameter electric butterfly valves should be bundled with straw ropes and transported in containers.
3.大口径阀门亦有简易木条框架固体包装，以免运输过程中碰损。
3.The large-diameter valve also should have a simple wooden frame for solid packing to avoid damage during transportation.
4.电动调节蝶阀,调节流量和截断流体的适合装置。
4.Electric adjustable butterfly valve is the best device for adjusting flow and cutting fluid.
