閥門扭矩的計算和蝶閥扭矩表
閥門無非分為氣動閥門和電動閥門兩種，主要銷售的類型也是氣動和電動的居多。氣動閥門和電動閥門主要的區(qū)別在于執(zhí)行器的不同，電動執(zhí)行器比氣動執(zhí)行器較為復雜，關于氣動和電動執(zhí)行器的選型，關鍵在于扭矩，閥門扭矩的數(shù)值決定了執(zhí)行機構。
扭矩指的是操作閥門所需的旋轉作用力，這個所需旋轉作用力的最大值是執(zhí)行機構的選擇要素，這個數(shù)值的計算，通常是來自某個牙齒下，軸承摩擦力和閥座/閥瓣干擾摩擦力所產(chǎn)生的扭矩的總和。由于摩擦力存在不確定因素，扭矩的計算較為復雜，數(shù)值存在差異性，下面是我廠蝶閥的部分扭矩數(shù)值，以供參考對照
