                       諾冠節(jié)流閥的應(yīng)用與故障排除
    英國(guó)NORGREN諾冠節(jié)流閥定義：
    節(jié)流閥是通過改變節(jié)流截面或節(jié)流長(zhǎng)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(jiǎn)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(bǔ)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(chǎng)合。
    英國(guó)NORGREN諾冠節(jié)流閥的特點(diǎn)
    1、構(gòu)造較簡(jiǎn)單，便于制造和維修，成本低。
    2、調(diào)節(jié)精度不高，不能作調(diào)節(jié)使用。
    3、密封面易沖蝕，不能作切斷介質(zhì)用。
    4、密封性較差。
    英國(guó)NORGREN諾冠安裝與維護(hù)事項(xiàng)節(jié)流閥的安裝與維護(hù)
    應(yīng)注意以下事項(xiàng)：
    該閥經(jīng)常需要操作，因此應(yīng)安裝在易于方面便操作的位置上。
    安裝時(shí)要注意介質(zhì)方向與閥體所標(biāo)箭頭方向保持一致。
