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，嘉興液壓閥油路。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(fù)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，嘉興液壓閥油路。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(yīng)能維持恒定，嘉興液壓閥油路，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(yīng)使壓差恒定或它們的比值恒定。液壓閥可用于遠(yuǎn)距離控制水電站油、氣、水管路系統(tǒng)的通斷。嘉興液壓閥油路</p><div

style="text-indent:25px">比例壓力控制閥是一個新的自力式調(diào)節(jié)閥種類。相對于手動調(diào)節(jié)閥，它的優(yōu)點是能夠自動調(diào)節(jié)；相對于電動調(diào)節(jié)閥，它的優(yōu)點是不需要外部動力。應(yīng)用實踐證明，在閉式水循環(huán)系統(tǒng)(如熱水供暖系統(tǒng)、空調(diào)冷凍水系統(tǒng))中，正確使用這種閥門，可以很方便地實現(xiàn)系統(tǒng)的流量分配；可以實現(xiàn)系統(tǒng)的動態(tài)平衡；可以很大簡化系統(tǒng)的調(diào)試工作；可以穩(wěn)定泵的工作狀態(tài)等。比例壓力控制閥屬于控制閥系列，主要作用是調(diào)節(jié)介質(zhì)的壓力、流量、溫度等等參數(shù)，是工藝環(huán)路中較終的控制元件。調(diào)節(jié)閥按行程特點可分為：直行程和角行程。直行程包括：單座閥、雙座閥、套筒閥、角形閥、三通閥、隔膜閥；角行程包括：蝶閥、球閥、偏心旋轉(zhuǎn)閥、全功能超輕型調(diào)節(jié)閥。調(diào)節(jié)閥按驅(qū)動方式可分為：氣動調(diào)節(jié)閥、電動調(diào)節(jié)閥和液動調(diào)節(jié)閥；按調(diào)節(jié)形式可分為：調(diào)節(jié)型、切斷型、調(diào)節(jié)切斷型；按流量特性可分為：線性、等百分比、拋物線、快開。調(diào)節(jié)閥適用于空氣、水、蒸汽、各種腐蝕性介質(zhì)、泥漿、油品等介質(zhì)。</p><p style="text-indent:25px">定壓溢流作用：在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中，定量泵提供的是恒定流量。當(dāng)系統(tǒng)壓力增大時，會使流量需求減小。此時溢流閥開啟，使多余流量溢回油箱，保證溢流閥進(jìn)口壓力，即泵出口壓力恒定（閥口常隨壓力波動開啟）。穩(wěn)壓作用：溢流閥串聯(lián)在回油路上，溢流閥產(chǎn)生背壓，運動部件平穩(wěn)性增加。系統(tǒng)卸荷作用：在溢流閥的遙控口串接溢小流量的電磁閥，當(dāng)電磁鐵通電時，溢流閥的遙控口通油箱，此時液壓泵卸荷。溢流閥此時作為卸荷閥使用。安全保護(hù)作用：系統(tǒng)正常工作時，閥門關(guān)閉。只有負(fù)載超過規(guī)定的極限（系統(tǒng)壓力超過調(diào)定壓力）時開啟溢流，進(jìn)行過載保護(hù)，使系統(tǒng)壓力不再增加（通常使溢流閥的調(diào)定壓力比系統(tǒng)較高工作壓力高10%～20%）。通斷式開關(guān)閥:這種閥是液壓系統(tǒng)中使用為普遍的。</p><div

style="text-indent:25px">伺服閥:這種閥主要是指電液伺服閥，在接收電氣模擬信號后，可相應(yīng)的調(diào)制流量與壓力，將信號再放大，它較早出現(xiàn)于二戰(zhàn)時期，目的在于滿足液壓系統(tǒng)向高速、高精度、大功率、高度自動化方向發(fā)展的需求，武器成為該技術(shù)的較早受益對象。隨著時間的推移，在響應(yīng)速度要求快、控制精度要求高的液壓伺服系統(tǒng)中，使用伺服閥作為控制閥，是基于該閥具有輸出效率高、反應(yīng)速度快和可電氣操縱、控制性良好等明顯優(yōu)勢，由此其被普遍應(yīng)用于要求控制準(zhǔn)確、迅速和程序控制能靈活變動的特定場合。電液伺服閥是一種理想的電子→液壓接口，可便捷高效的實現(xiàn)電信號→機(jī)械位移量→液壓信號的切換，并經(jīng)放大輸出與電控信號“連續(xù)成比例”的液壓功率。與通斷式開關(guān)閥相比，這類閥的成本較高，對液壓系統(tǒng)有嚴(yán)格染控制要求以及閉環(huán)系統(tǒng)的反饋要求，這都使得電氣控制變得更為復(fù)雜，維修難度也相應(yīng)提高，一定程度上限制了該元件的應(yīng)用。流量閥適用于需要進(jìn)行流量控制的水系統(tǒng)中，尤其適合于供熱。江蘇汽車液壓閥</p><p style="text-indent:25px">比例控制閥的結(jié)構(gòu)相對簡單，價格也較為便宜，可稱之為廉價的電液伺服元件。嘉興液壓閥油路</p><p style="text-indent:25px">換向型方向控制閥(簡稱換向閥)，是通過改變氣流通道而使氣體流動方向發(fā)生變化，從而達(dá)到改變氣動執(zhí)行元件運動方向目的。它包括氣壓控制換向閥、電磁控制換向閥、機(jī)械控制換向閥、人力控制換向閥和時間控制換向閥等一個完整的液壓系統(tǒng)由五個部分組成。液壓閥是用來控制液壓系統(tǒng)中油液的流動方向或調(diào)節(jié)其壓力和流量的，因此它可分為方向閥、壓力閥和流量閥三大類。一個形狀相同的閥，可以因為作用機(jī)制的不同，而具有不同的功能。壓力閥和流量閥利用通流截面的節(jié)流作用控制著系統(tǒng)的壓力和流量，而方向閥則利用通流通道的更換控制著油液的流動方向。這就是說，盡管液壓閥存在著各種各樣不同的類型，它們之間還是保持著一些基本共同之點的。嘉興液壓閥油路</p><p
