一、进口防爆型蝶阀用电动执行器概述

进口电动防爆蝶阀采用精密的U形弹性密封圈和三偏心多层次金属硬密封结构，被广泛用于介质温度≤425℃的治金 、电力、石油化工、以及给排水和市政建设等工业管道上。

The electric explosion-proof butterfly valve adopts a precise U-shaped elastic sealing ring and a three eccentric multi-level metal hard sealing structure, which is widely used in industrial pipelines such as metallurgy, power, petrochemical, water supply and drainage, and municipal construction with a medium temperature ≤ 425 ℃

二、进口防爆型电动蝶阀电动执行器特点

1、本阀采用三偏心密封结构，阀座与蝶板几乎无磨损，具有越观越紧的密封功能。

2、密封圈选用不锈钢制作，具有金属硬密封和弹性密封的双重优点，无论在低温和高温的情况下，均具有优良的密封性能,具有耐腐蚀,使用寿命长等特点。

3、碟板密封面采用堆焊钴基硬质合金，密封面耐磨损，使用寿命长。

4、大规格蝶板采用绗架结构，强度高，过流面积大，流阻小。

5、本阀具有双向密封功能，安装时不受介质流向的限制，也不受空间位置的影响，可在任何方向安装。

6、驱动装置可以多工位（旋转90°或180°）安装，便于用户使用。

1. This valve adopts a three eccentric sealing structure, with almost no wear on the valve seat and butterfly plate, and has a sealing function that becomes tighter and tighter.

2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance in both low and high temperature conditions, corrosion resistance, and long service life.

3. The sealing surface of the disc plate is made of cobalt based hard alloy, which is wear-resistant and has a long service life.

4. The large-sized butterfly plate adopts a quilted frame structure, which has high strength, large overcurrent area, and low flow resistance.

5. This valve has a bi-directional sealing function, and is not limited by the flow direction of the medium or affected by spatial position during installation. It can be installed in any direction.

6. The drive device can be installed at multiple workstations (rotating 90 ° or 180 °) for user convenience.
