簡介

我公司引進能夠國外先進技術(shù)的基礎(chǔ)上，采用精密的三偏心多層次金屬硬密封結(jié)構(gòu)，被廣泛用于介質(zhì)溫度≤425°C的冶金、電力、石油化工、以及給排水和市政建設(shè)等工業(yè)管道上，作調(diào)節(jié)流量和載斷流體使用。閥座與蝶板密封面均采用不同硬度和不銹鋼制作，具有良好的耐腐蝕性，使用壽命長，本閥均由雙向密封功能，產(chǎn)品符合國家GB/T13927閥門壓力試驗標準。

特點

1、本閥采用三偏心密封結(jié)構(gòu)，閥座與蝶板幾乎無磨損，具有越觀越緊的密封功能。

2、密封圈選用不銹鋼制作，具有金屬硬密封和彈性密封的雙重優(yōu)點，無論在低溫和高溫的情況下，均具有優(yōu)良的密封性能，具有耐腐蝕，使用壽命長等特點。

3、蝶板密封里采用堆焊鈷基硬質(zhì)合金，密封面耐磨損，使用壽命長。

4、大規(guī)格蝶板采用桁架結(jié)構(gòu)，強度高，過流面積大，流阻小。

5、本閥具有雙向密封功能，安裝時不受介質(zhì)流向的限制，也不受空間位置的影響，可在任何方向安裝。

6、驅(qū)動裝置可以多工位（旋轉(zhuǎn)90°或180°）安裝，便于用戶使用。

 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.

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.
