多個開啟壓力

功用：正向流通，反向受控流通

結(jié)構(gòu)：普通單向閥 液控裝置

工作原理：K不通壓力油，工作方式同普通單向閥；K通壓力油，閥口打開，可以反向流通

應(yīng)用：∵液控單向閥具有良好的反密封性

常用于保壓、鎖緊和平衡回路

安裝位置

單向閥就是止回閥 旋啟式止回閥安裝位置不受限制，通常安裝于水平管路，但也可以安裝于垂直管路或傾斜管路上。

注意事項

安裝單向止回閥時，應(yīng)特別注意介質(zhì)流動方向，應(yīng)使介質(zhì)正常流動方向與閥體上指示的箭頭方向相一致，否則就會截斷介質(zhì)的正常流動。底閥應(yīng)安裝在水泵吸水管路的底端。

止回閥關(guān)閉時，會在管路中產(chǎn)生水錘壓力，嚴(yán)重時會導(dǎo)致閥門、管路或設(shè)備的損壞，尤其對于大口管路或高壓管路，故應(yīng)引起止回閥選用者的高度注意。

止回閥只供防止各類管路或設(shè)備上流體介質(zhì)逆流的單向啟閉閥。

流量控制閥 利用調(diào)節(jié)閥芯和閥體間的節(jié)流口面積和它所產(chǎn)生的局部阻力對流量進(jìn)行調(diào)節(jié)，從而控制執(zhí)行元件的運(yùn)動速度。流量控制閥按用途分為 5種。(1)節(jié)流閥：在調(diào)定節(jié)流口面積后，能使載荷壓力變化不大和運(yùn)動均勻性要求不高的執(zhí)行元件的運(yùn)動速度基本上保持穩(wěn)定。(2)調(diào)速閥：在載荷壓力變化時能保持節(jié)流閥的進(jìn)出口壓差為定值。這樣，在節(jié)流口面積調(diào)定以后，不論載荷壓力如何變化，調(diào)速閥都能保持通過節(jié)流閥的流量不變，從而使執(zhí)行元件的運(yùn)動速度穩(wěn)定。

平衡閥的組成主要包括閥體，主閥芯，先導(dǎo)體，控制閥芯，彈簧座和阻尼孔。提升負(fù)載時，流動從A到B，使主閥芯打開。如果壓力下降（例如由于管子破裂），由于腔通著負(fù)載壓力，主閥芯立即關(guān)閉。下放負(fù)載（典型回路）這時流動從B至A。油口A經(jīng)方向閥通到油箱。足夠的油液進(jìn)入缸的有桿腔以造成所需的速度。油口X處的控制壓力與油口B的負(fù)載壓力之比為1:20。達(dá)到控制壓力時，主閥芯打開�？刂崎y芯使先導(dǎo)體升離閥座，而腔經(jīng)其內(nèi)孔和油口A向油箱回油。與此同時，在油口B中的負(fù)載壓力由于先導(dǎo)體在主閥芯中的縱向運(yùn)動而不再作用在腔。于是主閥芯卸載。

流量閥的工作原理主要取決于一個手動調(diào)節(jié)閥組和一個自動平衡閥組。其中，調(diào)節(jié)閥組作用是設(shè)定流量，而自動平衡閥組作用是維持流量恒定。系統(tǒng)流體的工作壓力為P1，手動調(diào)節(jié)閥的前后壓力分別為P2、P3。工作時，當(dāng)手動調(diào)節(jié)閥調(diào)到某一位置時，即人為確定了“設(shè)定流量”Kv即手動調(diào)節(jié)閥的流量系數(shù)，流量G=Kv（P2-P3），Kv為，Kv設(shè)定后，只要P2－P3不變，則流量G不變。當(dāng)系統(tǒng)流量加大時，(P2—P3)的實(shí)際值超過了允許的給定值，此時通過感壓膜和彈簧作用使自動調(diào)節(jié)閥組自動關(guān)小，直至流量重新維持到設(shè)定流量，反之亦然。
