简介
我公司引进能够*进技术的基础上，采用精密的三偏心多层次金属硬密封结构，被广泛用于介质温度≤425°C的冶金、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。阀座与蝶板密封面均采用不同硬度和不锈钢制作，具有良好的耐腐蚀性，使用寿命长，本阀均由双向密封功能，产品符合国家GB/T13927阀门压力试验标准。
Company introduction to on the basis of foreign advanced，the precision of the three eccentric multi-level metal hard seal structure，is widely used in medium temperature≤425°C of the metallurgy，electric power，petrochemical，and to the drainage and municipal construction and other industrial pipeline，adjust the flow and load flow.Valve seat and disc sealing surface life，the valve is a two-way sealing function，the product conforms to the national GB/T13927 valve pressure test standards.
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.
