進(jìn)口油用減壓閥德國(guó)洛克品牌品質(zhì)保證

進(jìn)口油用減壓閥結(jié)構(gòu)特點(diǎn)：

◆調(diào)壓范圍：它是指減壓閥輸出壓力P2的可調(diào)范圍，在此范圍內(nèi)要求達(dá)到規(guī)定的精度。調(diào)壓范圍主要與調(diào)壓彈簧的剛度有關(guān)。

◆壓力特性：它是指流量g為定值時(shí)，因輸入壓力波動(dòng)而引起輸出壓力波動(dòng)的特性。輸出壓力波動(dòng)越小，減壓閥的特性越好。輸出壓力必須低于輸入壓力—定值才基本上不隨輸入壓力變化而變化。

◆流量特性：它是指輸入壓力—定時(shí)，輸出壓力隨輸出流量g的變化而變化的持性。當(dāng)流量g發(fā)生變化時(shí)，輸出壓力的變化越小越好。一般輸出壓力越低，它隨輸出流量的變化波動(dòng)就越小。
