(完整word版)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。一管式連接直通單向閥一有一個(gè)方向無泄漏的封閉一有五種開啟壓力一板式連接一插入式連接圖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)不帶彈簧型號(hào)意義S二單向閥地徑管式板式K6=6一68=S810=10101015=15一1520=20202025=2
