style="text-indent:25px">簡稱液壓閥在液壓系統(tǒng)中的功用是通過控制調節(jié)液壓系統(tǒng)中油液的流向、壓力和流量，使執(zhí)行器及其驅動的工作機構獲得所需的運動方向、推力（轉矩）及運動速度（轉速）等。任何一個液壓系統(tǒng)，不論其如何簡單，都不能缺少液壓閥；同一工藝目的的液壓機械設備，通過液壓閥的不同組合使用，可以組成油路結構截然不同的多種液壓系統(tǒng)方案。因此，液壓閥是液壓技術中品種與規(guī)格較多、應用較普遍、較活躍的部分（元件）；一個新設計或正在運轉的液壓系統(tǒng)，能否按照既定要求正?？煽康剡\行，在很大程度上取決于其中所采用的各種液壓閥的性能優(yōu)劣及參數(shù)匹配是否合理。</p><p style="text-indent:25px">減壓閥是通過調節(jié)，將進口壓力減至某一需要的出口壓力，并依靠介質本身的能量，使出口壓力自動保持穩(wěn)定的閥門。從流體力學的觀點看，減壓閥是一個局部阻力可以變化的節(jié)流元件，即通過改變節(jié)流面積，使流速及流體的動能改變，造成不同的壓力損失，從而達到減壓的目的。然后依靠控制與調節(jié)系統(tǒng)的調節(jié)，使閥后壓力的波動與彈簧力相平衡，使閥后壓力在一定的誤差范圍內保持恒定。調壓范圍：它是指減壓閥輸出壓力P2的可調范圍，在此范圍內要求達到規(guī)定的精度。調壓范圍主要與調壓彈簧的剛度有關。換向閥：改變不同管路間的通、斷關系。</p><div

1）由于節(jié)流閥、調速閥在液壓系統(tǒng)中的主要功能是調節(jié)系統(tǒng)或所在支路的流量，所以統(tǒng)稱流量閥。 2）有時流量閥實際上是指調速閥。 3）從壓力流量基本公式看，節(jié)流閥只是改變閥口過流面積的大小，所控制的流量還要受其前后壓差變化的影響；調速閥（有時直接稱流量閥）采取或者串聯(lián)定差減壓閥，或者并聯(lián)定差溢流閥，分別構成二通調速閥（可串聯(lián)配置在前、后，或并聯(lián)于執(zhí)行器前）和三通調速閥（只能串聯(lián)于執(zhí)行器前，而且只能控制一個負載）；液壓閥按功能分類：流量閥（節(jié)流閥、調速閥，分流集流閥）。金華液壓閥批發(fā)</p><p style="text-indent:25px">液壓閥按安裝方式分：板式閥，管式閥，疊加閥，螺紋插裝閥，蓋板閥。金華液壓閥批發(fā)</p><p style="text-indent:25px">液壓控制閥——減壓閥: 1.工作原理：按工作原理和結構，減壓閥分直動式和先導式兩類。 2.功用及性能要求：減壓閥用來降低系統(tǒng)中某一回路的壓力。使其出口壓力降低且恒定的減壓閥稱為定值輸出減壓閥；使其出口壓力與某一負載壓力之差恒定的減壓閥稱為定差減壓閥；使其入口壓力與出口壓力比值一定的減壓閥稱為定比減壓閥。對定值輸出減壓閥的要求是：不管入口壓力如何變化，出口壓力應能維持恒定，且不受通過閥的流量變化的影響。對定差或定比減壓閥來說，則要求不管入口壓力或出口壓力如何變化，應使壓差恒定或它們的比值恒定。金華液壓閥批發(fā)</p></p><br
