將多功能水泵控制閥、微阻緩閉蝶閥和普通止回閥三種設置情況正造成的停泵水錘結果列表比較如下:水錘邊界條件多功能水泵控制閥電動蝶閥+普通止回閥電動蝶閥+微阻緩閉蝶閥Hmax/Ho1.2251.52.4βmax/βo.4.43種閥水錘邊界條件比較Hmanx—停泵壓力峰值Ho—正常工作壓力βmax—停泵后機組逆轉速βo—額定轉速(145r/min)從上表可以看出,多功能水泵控制閥對于消除停泵水錘有明顯效果,完全符合《泵站設計規(guī)范》以及《水泵操作規(guī)程》;多功能水泵控制閥還能實現(xiàn)啟泵緩慢開啟,能夠消除開泵水錘。

此外還可按用途對螺紋鋼進行分類,如分為鋼筋混凝土用普通鋼筋及鋼筋混凝土用熱處理鋼筋等。我國的鋼筋混凝土用熱軋帶肋鋼筋按標準,牌號由HRB和牌號的屈服點值構成。R、B分別為熱軋(Hotroll帶肋(Ribb鋼筋(Bars)三個詞的英文首位字母。熱軋帶肋鋼筋分為HRB335(老牌號為2MnSi)、HRB4(老牌號為2MnSiV、2MnSiN2Mnti)、HRB5三個牌號。
