供应 法兰式金属硬密封蝶阀

产品详情

 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、蝶板密封里采用堆焊钴基硬质合金，密封面耐磨损，使用寿命长。

4、大规格蝶板采用桁架结构，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.The valve uses three eccentric sealing structure，the valve seat and disc almost no wear，with the more closely the sealing function.

2.Sealing ring selection of stainless steel production，with a metal hard sealing and flexible sealing double advantages，both in the case of low temperature and high temperature，have excellent sealing performance，with corrosion resistance，long life and so on.

3.The disc sealing surface using cobalt based alloy welding，sealing surface wear resistance，long service life.

4.Large formatdiscusinglatticestructure，high strength，large flow area，flow resistance is small.

5.The valve has a two-way sealing function，the installation is not restricted by the direction of the media，nor by the impact of spatial position，can be installed in any direction.

6.The driving device can be multi station (rotating 90°or180°)to install，easy to use.
