产品结构特点 Construction features
1、蝶板密封圈为软硬层叠式金属片，具有金属硬密封和弹性密封的双重优点，无论在低温和高温情况下，均具有优良的密封性能。
2、采用三维偏心结构，阀座与蝶板几乎无磨擦，具有越关越紧的密封功能。
3、阀体密封面，采用堆焊不锈钢、钴基硬质合金，密封面耐磨损，使用寿命长。
4、结构独特，操作灵活、省力、方便、不受介质压力的高、低影响，密封性能可靠，使用寿命长。
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.
