明杆閘閥與暗杆閘閥構造與區别

2015-10-09 09:36:09| 發布者: 廣州富山閥門有限公司| 查看: 2156

閘閥按閥杆的構造可分為:

      
       1、明杆閘閥:閥杆螺母在閥蓋或支架上,開閉閘闆時,用旋轉閥杆螺母來實現閥杆的升降。這種結構對閥杆的潤滑有利,開閉程度明顯,因此被廣泛采用。
      
        2、暗杆閘閥:閥杆螺母在閥體内,與介質直接接觸。開閉閘闆時,用旋轉閥杆來實現。這種結構的優點是:閘閥的高度總保持不變,因此安裝空間小,适用于大口徑或對 安裝空間受限制的閘閥。此種結構要裝有開閉指示器,以指示開閉程度。這種結構的缺點是:閥杆螺紋不僅無法潤滑,而且直接接受介質侵蝕,容易損壞。明杆閘閥 和暗杆閘閥的差異
      
     主要區别:
      
    1.暗杆法蘭閘閥的提升螺杆是隻旋轉而無上和下移動,外露的隻是一根杆,其螺母是固定在閘闆上,通過螺杆的旋轉來提升閘闆,沒有可見的門架;暗杆閘閥的傳動螺紋位于閥體内部,在啟閉過程中,閥杆隻做旋轉動動,閘闆在閥體内升降。因此,閥門的高度尺寸小。明杆法蘭閘閥 的提升螺杆是外露的,螺母緊貼手輪且是固定的(不旋轉也不軸向移動),通過旋轉螺杆來提升閘闆,螺杆與閘闆隻有相對的旋轉運動而無相對的軸向位移,外觀為 有門形支架。明杆閘閥和暗杆閘閥的差異。
      
    2.暗杆閥門就是看不見絲杠,而明杆的就是能看見絲杆的。
      
      3.暗杆閥門在開關時方向盤與閥杆是連接在一起相對不動的,它是通過閥杆在固定點轉動來帶動閥瓣向上提升和下閘來完成啟閉的。明杆閥門則是通過閥杆與方向盤的螺紋傳動來提升或者降下閥瓣。
      4.明杆閘閥的閥杆帶動閘闆一起升降,閥杆上的傳動螺紋在閥體外部,因此,可根據閥杆的運動方向和位置直觀地判斷閘闆啟閉和位置,而且傳動螺紋便于潤滑和不受流體腐蝕,但它要求有較大的安裝空間。
