產品結構特點 Construction features
1、蝶板密封圈為軟硬層疊式金屬片,具有金屬硬密封和彈性密封的雙重優點,無論在低溫和高溫情況下,均具有優良的密封性能。
2、采用三維偏心結構,閥座與蝶板幾乎無磨擦,具有越關越緊的密封功能。
3、閥體密封面,采用堆焊不銹鋼、鈷基硬質合金,密封面耐磨損,使用壽命長。
4、結構,操作靈活、省力、方便、不受介質壓力的高、低影響,密封性能可靠,使用壽命長。
1. The butterfly plate sealing ring is a soft and hard laminated metal sheet, which has the double advantages of hard sealing and elastic sealing. It has excellent sealing performance both in low temperature and high temperature.2. Using the three-dimensional eccentric structure, the seat and butterfly plate are almost friction-free, and have the sealing function with the closer and tighter.
3. Body airtight cover, use of stacking stainless steel, cobalt base hard alloy, sealing surface wear resistance, long service life.
4. The structure is unique, the operation is flexible, the labor-saving, convenient, is not subjected to the medium pressure high, the low impact, the sealing performance is reliable, the service life is long.
