性能

(1)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)。

(2)壓力特性：它是指流量g為定值時，因輸入壓力波動而引起輸出壓力波動的特性。輸出壓力波動越小，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。

(3)流量特性：它是指輸入壓力—定時，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，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就越小

減壓閥

減壓閥是利用液流流過縫隙產(chǎn)生壓力損失，使其出口壓力低于進(jìn)口壓力的壓力控制閥。

按調(diào)節(jié)要求不同，有定值減壓閥，定差減壓閥，定比減壓閥。

定值減壓閥的結(jié)構(gòu)原理

減壓閥起減壓作用且保證出口壓力為定值的條件是:當(dāng)出口壓力大于減壓閥的調(diào)定壓力，使其先導(dǎo)閥開啟。

直動式減壓閥

減壓閥的功用與特點：

減壓閥用在液壓系統(tǒng)中獲得壓力低于系統(tǒng)壓力的二次油路上

與溢流閥比較:

減壓閥是出口壓力控制，保證出口壓力為定值;溢流閥是進(jìn)口壓力控制，保證進(jìn)口壓力為定值。

減壓閥閥口常開;

溢流閥閥口常閉。

減壓閥有單獨的泄油口;溢流閥彈簧腔的泄漏油經(jīng)閥體

內(nèi)流道內(nèi)泄至出口。

減壓閥與溢流閥-樣有遙控口。

減壓閥可將閥前管路較高的液體壓力減少至閥后管路所需的水平。這里的傳輸介質(zhì)主要是水。減壓閥廣泛用于高層建筑、城市給水管網(wǎng)水壓過高的區(qū)域、礦井及其他場合，以保證給水系統(tǒng)中各用水點獲得適當(dāng)?shù)姆��?wù)水壓和流量。鑒于水的漏失率和浪費程度幾乎同給水系統(tǒng)的水壓大小成正比，因此減壓閥具有改善系統(tǒng)運行工況和潛在節(jié)水作用，據(jù)統(tǒng)計其節(jié)水效果約為30%。

作用原理：減壓閥的是靠閥內(nèi)流道對水流的局部阻力降低水壓，水壓降的范圍由連接閥瓣的薄膜或活塞兩側(cè)的進(jìn)出口水壓差自動調(diào)節(jié)。定比減壓原理是利用閥體中浮動活塞的水壓比控制，進(jìn)出口端減壓比與進(jìn)出口側(cè)活塞面積比成反比。這種減壓閥工作平穩(wěn)無振動；閥體內(nèi)無彈簧，故無彈簧銹蝕、金屬疲勞失效之慮；密封性能良好不滲漏，因而既減動壓（水流動時）又減靜壓（流量為0時）；特別是在減壓的同時不影響水流量。

DR型壓力閥是先導(dǎo)式減壓閥。它用于降低系統(tǒng)壓力。

它主要由旋入式插裝閥（濾芯）和外殼組成，可以選擇是否帶有止回閥（僅用于底板安裝）。

在靜止位置，閥門打開。液壓油能夠從輸入通道通過主控制閥芯（1）自由流動到輸出通道。出口通道中的壓力通過孔（2）施加到主控制閥芯（1）的彈簧加載側(cè)。同時，壓力通過孔（3）和（4）作用在主控制閥芯（1）的與彈簧相對的一側(cè)。

如果出口通道中的壓力超過在彈簧（6）上設(shè)定的值，則先導(dǎo)提升閥（5）打開。

液壓油從主控制閥芯（1）的彈簧加載側(cè)通過噴嘴（7）和先導(dǎo)提升閥（5）流入彈簧腔（8）。

主控制閥芯（1）處于其控制位置，并將彈簧（6）上設(shè)定的出口通道中的值保持恒定。從彈簧腔（8）返回的先導(dǎo)油總是通過Y口（9）從外部實現(xiàn)。

在底板安裝版本“ P”中，可以選擇安裝一個止回閥（10），以實現(xiàn)從通道A到B的自由回流。

換向閥主要由閥體、密封組件、凸輪、閥桿、手柄和閥蓋等零部件組成(圖1)。閥門由手柄驅(qū)動，通過手柄帶動閥桿與凸輪旋轉(zhuǎn)，凸輪具有定位驅(qū)動與鎖定密封組件的開啟與關(guān)閉功能。手柄逆時針旋轉(zhuǎn)，兩組密封組件分別在凸輪的作用下關(guān)閉下端的兩個通道，上端的兩個通道分別與管道裝置的進(jìn)口相通。反之，上端的兩個通道關(guān)閉，下端兩個通道與管道裝置的進(jìn)口相通，實現(xiàn)了不停車換向。
