一、产品概述Product Overview：

　　 引进能够国外*技术的基础上，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，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。该阀采用三偏心结构，阀座与碟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，本阀军邮双向密封功能，产品符合GB/T13927-92阀门压力试验标准。

The introduction of foreign advanced technology can be based on the use of sophisticated J-shaped elastic ring and three eccentric multi-level metal seal structure, is widely used in medium temperature ≤ 425 ℃ of metallurgy, electric power, petrochemical, and municipal water supply and drainage and pipeline construction and other industries, for regulating the flow and load disconnection body to use. The valve is a three-eccentric structure, seat and disc sealing surface and are made ??of stainless steel with different hardness, good corrosion resistance, long service life, the two-way valve military postal sealing function, valve product line with national GB/T13927-92 pressure test standards.

二、产品特点Features：

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, the valve is a three-eccentric sealing structure, seat and disc almost no wear, with a more functional view of the more tight seal.
2, the ring made ??of stainless steel production, with a metal seal and seal the dual advantages of flexibility, both in the case of low and high temperatures, both with excellent sealing performance, corrosion resistance, long service life.
3, the disc sealing surface using cobalt-based alloy welding, sealing surface wear resistance, long service life.
4, large-format disc using lattice structure, high strength, over-flow area, flow resistance.
5, the sealing function with two-way valve, the flow of the installation media from the restrictions, but also from the impact of spatial location, can be installed in any direction.
6, the drive can be multi-position （rotated 90 ° or 180 °） to install, easy to use.
