一、產(chǎn)品概述Product Overview：

　　 引進(jìn)能夠*技術(shù)的基礎(chǔ)上，采用精密的J形彈性密封圈和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℃的治金 、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。該閥采用三偏心結(jié)構(gòu)，閥座與碟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(zhǎng)，本閥軍郵雙向密封功能，產(chǎn)品符合國(guó)家GB/T13927-92閥門(mén)壓力試驗(yàn)標(biāo)準(zhǔn)。

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、產(chǎn)品特點(diǎn)Features：

1、本閥采用三偏心密封結(jié)構(gòu)，閥座與蝶板幾乎無(wú)磨損，具有越觀(guān)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(diǎn)，無(wú)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(zhǎng)等特點(diǎn)。
3、碟板密封面采用堆焊鈷基硬質(zhì)合金，密封面耐磨損，使用壽命長(zhǎng)．
4、大規(guī)格蝶板采用絎架結(jié)構(gòu)，強(qiáng)度高，過(guò)流面積大，流阻小。
5、本閥具有雙向密封功能，安裝時(shí)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(dòng)裝置可以多工位（旋轉(zhuǎn)90°或180°）安裝，便于用戶(hù)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.
