                安裝不銹鋼閥門時的注意事項
                發布時間:2013-09-09 12:14:35
                不銹鋼閥門安裝的質量直接影響到它的使用,所以必須認真注意,仔細按照說明進行安裝操作。
                  安裝施工必須小心,切忌撞擊脆性材料制作的閥門。
                  安裝前,應將閥門作一檢查,核對規格型號,鑒定有無損壞,尤其對于閥桿。還要轉動幾下,看是否歪斜,因為運輸過程中,最易撞歪閥桿。還要清除閥內的雜物。
                  閥門起吊時,繩子不要系在手輪或閥桿上,以免損壞這些部件,應該系在法蘭上。
                  對于閥門所連接的管路,一定要清掃干凈??捎脡嚎s空氣吹去氧化鐵屑、泥砂、焊渣和其他雜物。這些雜物,不但容易擦傷閥門的密封面,其中大顆粒雜物(如焊渣),還能堵死小閥門,使其失效。
                  安裝螺口閥門時,應將密封填料(線麻加鉛油或聚四氟乙烯生料帶),包在管子螺紋上,不要弄到閥門里,以免閥內存積,影響介質流通。
                  安裝法蘭氣動閥門時,要注意對稱均勻地把緊螺栓。閥門法蘭與管子法蘭必須平行,間隙合理,以免閥門產生過大壓力,甚至開裂。對于脆性材料和強度不高的閥門,尤其要注意。須與管子焊接的閥門,應先點焊,再將關閉件全開,然后焊死。
