單向閥Check Valve[1]
單向閥又稱止回閥或逆止閥。用于液壓系統(tǒng)中防止油流反向流動,或者用于氣動系統(tǒng)中防止壓縮空氣逆向流動。
單向閥有直通式和直角式兩種。直通式單向閥用螺紋連接安裝在管路上。直角式單向閥有螺紋連接、板式連接和法蘭連接三種形式。液控單向閥也稱閉鎖閥或保壓閥,它與單向閥相同,用以防止油液反向流動。但在液壓回路中需要油流反向流動時又可利用控制油壓,打開單向閥,使油流在兩個方向都可流動。液控單向閥采用錐形閥芯,因此密封性能好。在要求封閉油路時,可用此閥作為油路的單向鎖緊而起保壓作用。液控單向閥控制油的泄漏方式有內泄式和外泄式二種。在油流反向出口無背壓的油路中可用內泄式;否則需用外泄式,以降低控制油壓力。單向閥就是止回閥 旋啟式止回閥安裝位置不受限制,通常安裝于水平管路,但也可以安裝于垂直管路或傾斜管路上。
注意事項
安裝止回閥時,應特別注意介質流動方向,應使介質正常流動方向與閥體上指示的箭頭方向相*,否則就會截斷介質的正常流動。底閥應安裝在水泵吸水管路的底端。
止回閥關閉時,會在管路中產生水錘壓力,嚴重時會導致閥門、管路或設備的損壞,尤其對于大口管路或高壓管路,故應引起止回閥選用者的高度注意。
止回閥只供防止各類管路或設備上流體介質逆流的單向啟閉閥。
