產品簡介

D673H氣動彈性金屬密封蝶閥采用一個“U”型不銹鋼密封圈，

該精密的彈性密封圈與經過拋光的蝶板三維偏心接觸。

解決了傳統偏心蝶閥在啟閉0°～10°瞬間密封面仍處于滑動接觸摩擦的弊病,

實現蝶板在開啟瞬間密封面即分離,關閉接觸即密封的效果,達到延長使用壽命、密封性能最佳的目的。

因此被廣泛地應用到介質溫度≤550℃的冶金、電力、石油、化工、空氣、

煤氣、可燃氣體以及給排水等腐蝕性介質的管道上，是調節流量和截斷流體的最佳裝置

產品特點

1、該蝶閥結構簡單、緊湊、重量輕、易于安裝和拆卸、維修方便；

2、本蝶閥采用不銹鋼“U”型密封圈，具有一定的彈性無論在高溫、低溫的情況下，它與蝶板均具有優良的密封性；

3、本蝶閥的三維偏心距，經過嚴格的計算，“U”型密封圈與蝶板幾乎無磨擦，使用壽命長，并具有越關越緊的功能；

4、蝶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；

5、本蝶閥結構獨特，“開關”僅需轉動閥桿90°即可完成。操作靈活、方便、省力、

不受介質壓力的高低影響，密封性能可靠；

采用標準

設計標準 :GB/T12238-1989

法蘭連接尺寸: GB/T9113.1-2000；GB/T9113.2-2000 GB/T9115.1-2000；GB/T9115.2-2000

結構長度:GB/T12221-1989

壓力試驗:GB/T13927-1992；JB/T9092-1999 執行機構

采用新型系列GT型氣動執行器，有雙作用式和單作用式（彈簧復位），齒輪傳動，安全可靠；

大口徑閥門采用系列AW型氣動執行器拔叉式傳動，結構合理，輸出扭矩大，有雙作用式和單作用式

1、齒輪式雙活塞，輸出力矩大，體積小。

2、氣缸選用鋁金材料，重量輕、外形美觀。

3、可在頂部、底部安裝手動操作機構。

4、齒條式連接可調節開啟角度、額定流量。

5、執行器可選帶電訊號反饋指示及各類附件以實現自動化操作。

6、IS05211標準連接為產品的安裝更換提供了方便。

7、兩端調的節螺釘可使標準產品在0°和90°有±4°的可調范圍。確保與閥門的同步精度。
