                  雙向流硬碰硬旋球閥安裝調試及安裝方向注意事項

                  雙向流硬碰硬旋球閥安裝調試及安裝方向注意事項:

                  1、雙向流硬碰硬旋球閥前后1DN長度內的管道上不能有縮徑、彎管、波紋管等;

                  2、如果雙向流硬碰硬旋球閥前后緊湊著安裝蝶閥、液力自動閥、蝶式止回閥或蝶式緩閉止回閥,相鄰兩閥之間相隔直管段為不小于1DN的距離;

                  3、閥板在裝配、安裝、運輸、維護檢修或拆開時,要注意不能碰密封面,要采取嚴格的保護措施;

                  4、雙向流硬碰硬旋球閥在裝配、運輸、安裝、保管時閥板要呈關閉狀態;

                  5、如有必要需拆開雙向流硬碰硬旋球閥時,注意不要損壞軸套,防止圓錐丟失和軸套的散失;

                  6、裝配、安裝、維護檢修完畢要清除干凈雙向流硬碰硬旋球閥內的金屬屑、污物、雜質,堆焊的密封面要抹拭干凈;

                  7、無論臥式安裝或立式安裝,一定要注意旋球閥的安裝方向,當無法確定流道方向時,雙向流硬碰硬旋球閥打開時,閥板為大面端頭朝向進水方向;

                  8、長期不使用雙向流硬碰硬旋球閥請用黃油涂復密封面或油紙、蠟紙覆蓋密封面。
