REXROTH液控單向閥R900403578 SV10PA2-4X/V

節(jié)流閥是通過改變節(jié)流截面或節(jié)流長度以控制流體流量的閥門。將節(jié)流閥和單向閥并聯(lián)則可組合成單向節(jié)流閥。節(jié)流閥和單向節(jié)流閥是簡易的流量控制閥，在定量泵液壓系統(tǒng)中，節(jié)流閥和溢流閥配合，可組成三種節(jié)流調(diào)速系統(tǒng)，即進(jìn)油路節(jié)流調(diào)速系統(tǒng)、回油路節(jié)流調(diào)速系統(tǒng)和旁路節(jié)流調(diào)速系統(tǒng)。節(jié)流閥沒有流量負(fù)反饋功能，不能補償由負(fù)載變化所造成的速度不穩(wěn)定，一般僅用于負(fù)載變化不大或?qū)λ俣确€(wěn)定性要求不高的場合。

SV系列液控單向閥液控單向閥有一個開啟比的參數(shù),同樣結(jié)構(gòu)形式的閥,外泄式的比內(nèi)泄時的開啟比要大.在選擇液控單向閥時要注意開啟比要與油缸的面積比匹配要比油缸的面積比大,目前使用的油缸的面積比一般在2左右,而目前現(xiàn)有的液控單向閥產(chǎn)品的開啟比都比2大得多,都可以直接選擇不必進(jìn)行匹配計算.但如果由于特殊情況需要采用大面積比的油缸時,就要考慮閥的開啟比的問題

SV型閥是錐閥結(jié)構(gòu)的液控單向閥,它可以在關(guān)閉方向開啟而讓油液自由流動.

此類閥用于有壓液壓回路部分的隔離,當(dāng)管路破裂時,作為防止負(fù)載失壓的安全措施,或避免執(zhí)行器在液壓閉鎖時的爬行或漂移.
