一、電動對夾式硬密封球閥產品概述Product Overview:
上海湖泉閥門有限公司生產的電動對夾式硬密封球閥引進能夠*技術的基礎上,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構,被廣泛用于介質溫度≤425℃的治金 、電力、石油化工、以及給排水和市政建設等工業管道上,作調節流量和載斷流體使用。該閥采用三偏心結構,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,本閥軍郵雙向密封功能,產品符合國家GB/T13927-92閥門壓力試驗標準。
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 otherindustries, 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、電動對夾式硬密封球閥產品特點Features:
1、本閥采用三偏心密封結構,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點,無論在低溫和高溫的情況下,均具有優良的密封性能,具有耐腐蝕,使用壽命長等特點。
3、碟板密封面采用堆焊鈷基硬質合金,密封面耐磨損,使用壽命長.
4、大規格蝶板采用絎架結構,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、驅動裝置可以多工位(旋轉90°或180°)安裝,便于用戶使用。
1, the valve is a three-eccentric sealing structure, seat and disc almost no wear, with a more functional view ofthe 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 fromthe 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.
