S型單向閥-力士樂液壓閥樣本

1、S型單向閥 特點(diǎn)S型單向閥的作用是使油液只能向一個(gè)方向流動(dòng)而另一個(gè)方向止流，如圖1-1所示。管式連接直通單向閥有一個(gè)方向無泄漏的封閉有五種開啟壓力板式連接插入式連接 圖1-1 S型單向閥功能說明 S型單向閥閥芯的行程受到卡圈的限制，內(nèi)裝彈簧支承開閉行程并保持閥芯處于關(guān)閉狀態(tài)。S型單向閥為錐閥式結(jié)構(gòu)，壓力損失小，有五種開啟壓力和三種連接方式，管式和板式閥結(jié)構(gòu)如圖2-1和圖2-2所示。該閥主要用于泵的出口處，作背壓閥和旁路閥用。 圖2-1 板式閥結(jié)構(gòu)圖 圖2-2 板式閥結(jié)構(gòu)圖機(jī)能符號(hào)型號(hào)意義直通式K1K2K3規(guī)格6301889301896301903規(guī)格8301890301897301904規(guī)格1
