一、进口对夹式硬密封蝶阀产品概述

进口对夹式硬密封蝶阀（美国威盾VTON），Wafer type hard sealing butterfly valve也叫双偏心硬密封蝶阀，金属硬密封蝶阀，采用精密的J形弹性密封圈和三偏心多层次金属硬密封结构的蝶阀，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，作调节流量和载断流体使用。

Wafer type hard sealing butterfly valve (VTON), also known as double eccentric hard sealing butterfly valve, is a metal hard sealing butterfly valve that uses a precision J-shaped elastic sealing ring and a three eccentric multi-level metal hard sealing structure. It is widely used in industrial pipelines such as metallurgy, power, petrochemical, water supply and drainage, and municipal construction, where the medium temperature is ≤ 425 ℃, for regulating flow and breaking fluid.

二、进口对夹式硬密封蝶阀产品特点

1、对夹式硬密封蝶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、对夹式硬密封蝶阀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、对夹式硬密封蝶阀蝶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、对夹式硬密封蝶阀大规格蝶板采用绗架结构，强度高，过流面积大，流阻小

5、对夹式硬密封蝶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. The clamp type hard sealed butterfly 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 as it is observed

2. The sealing ring of the clamp type hard sealed butterfly valve 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 butterfly plate of the clamp type hard sealed butterfly valve is made of cobalt based hard alloy by overlay welding, which is wear-resistant and has a long service life

4. The large-sized butterfly plate of the clamp type hard sealed butterfly valve adopts a quilted frame structure, which has high strength, large flow area, and small flow resistance

5. The clamp type hard sealed butterfly valve has a bi-directional sealing function, and is not limited by the flow direction of the medium or the influence of spatial position during installation. It can be installed in any direction

6. The driving device can be installed at multiple workstations (rotating 90 ° or 180 °), making it convenient for users to use
