德國原裝Rexroth力士樂單向閥

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(dòng),或者用于氣動(dòng)系統(tǒng)中防止壓縮空氣逆向流動(dòng)。
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(dòng)。但在液壓回路中需要油流反向流動(dòng)時(shí)又可利用控制油壓，打開單向閥，使油流在兩個(gè)方向都可流動(dòng)。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(shí)，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(nèi)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(nèi)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(xiàng)

安裝止回閥時(shí)，應(yīng)特別注意介質(zhì)流動(dòng)方向，應(yīng)使介質(zhì)正常流動(dòng)方向與閥體上指示的箭頭方向相*，否則就會(huì)截?cái)嘟橘|(zhì)的正常流動(dòng)。底閥應(yīng)安裝在水泵吸水管路的底端。
止回閥關(guān)閉時(shí)，會(huì)在管路中產(chǎn)生水錘壓力，嚴(yán)重時(shí)會(huì)導(dǎo)致閥門、管路或設(shè)備的損壞，尤其對(duì)于大口管路或高壓管路，故應(yīng)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(shè)備上流體介質(zhì)逆流的單向啟閉閥。
