組合組合氣缸一般指氣缸與液壓缸相組合形成的氣-液阻尼缸、氣-液增壓缸等。*，通常氣缸采用的工作介質(zhì)是壓縮空氣，其特點是動作快，但速度不易控

制，當(dāng)載荷變化較大時，容易產(chǎn)生“爬行”或“自走”現(xiàn)象；而液壓缸采用的工作介質(zhì)是通常認(rèn)為不可壓縮的液壓油，其特點是動作不如氣缸快，但速度易于控制，

當(dāng)載荷變化較大時，采用措施得當(dāng)，一般不會產(chǎn)生“爬行”和“自走”現(xiàn)象。把氣缸與液壓缸巧妙組合起來，取長補短，即成為氣動系統(tǒng)中普遍采用的氣-液阻尼

缸。氣-液阻尼缸工作原理見圖42.2-5。實際是氣缸與液壓缸串聯(lián)而成，兩活塞固定在同一活塞桿上。液壓缸不用泵供油，只要充滿油即可，其進出口間裝有

液壓單向閥、節(jié)流閥及補油杯。當(dāng)氣缸右端供氣時，氣缸克服載荷帶動液壓缸活塞向左運動（氣缸左端排氣），此時液壓缸左端排油，單向閥關(guān)閉，油只能通過節(jié)流

閥流入液壓缸右腔及油杯內(nèi)，這時若將節(jié)流閥閥口開大，則液壓缸左腔排油通暢，兩活塞運動速度就快，反之，若將節(jié)流閥閥口關(guān)小，液壓缸左腔排油受阻，兩活塞

運動速度會減慢。這樣，調(diào)節(jié)節(jié)流閥開口大小，就能控制活塞的運動速度?？梢钥闯?，氣液阻尼缸的輸出力應(yīng)是氣缸中壓縮空氣產(chǎn)生的力（推力或拉力）與液壓缸中

油的阻尼力之差。

設(shè)定壓力：0.05～0.7Mpa于先導(dǎo)活塞式減壓閥。由主閥和導(dǎo)閥兩部分組成。主閥主要由閥座、主閥盤、活塞、彈簧等零件組成。導(dǎo)閥主要由閥座、閥瓣、膜片、彈簧、調(diào)節(jié)彈簧等零件組成。通過調(diào)節(jié)調(diào)節(jié)彈簧壓力設(shè)定出口壓力、利用膜片傳感出口壓力變化，通過導(dǎo)閥啟閉驅(qū)動活塞調(diào)節(jié)主閥節(jié)流部位過流面積的大小，實現(xiàn)減壓穩(wěn)壓功能。先導(dǎo)式減壓閥——該閥門的減壓比必須在一定程度上高于系統(tǒng)值；

即使在大或者小流量時它也應(yīng)該能夠?qū)φ饔没蛘叻醋饔每刂菩盘栕龀鲰憫?yīng)。這些閥門應(yīng)該針對有用控制范圍選擇，即大流量的20%到80%。正常為等比型或者具有等比特性。這些類型的閥門本身具有比例控制所要求的佳流量特性及流量范圍。

SMC減壓閥，SMC進口先導(dǎo)式減壓閥是采用控制閥體內(nèi)的啟閉件的開度來調(diào)節(jié)介質(zhì)的流量，將介質(zhì)的壓力降低，同時借助閥后壓力的作用調(diào)節(jié)啟閉件的開度，使閥后壓力保持在一定范圍內(nèi)，在進口壓力不斷變化的情況下，保持出口壓力在設(shè)定的范圍內(nèi)，保護其后的生活生產(chǎn)器具。本類閥門在管道中一般應(yīng)當(dāng)水平安裝。

是氣動調(diào)節(jié)閥的一個*配件，主要作用是將氣源的壓力減壓并穩(wěn)定到一個定值，以便于調(diào)節(jié)閥能夠獲得穩(wěn)定的氣源動力用于調(diào)節(jié)控制。按結(jié)構(gòu)形式可分為膜片式、彈簧薄膜式、活塞式、杠桿式和波紋管式；按閥座數(shù)目可人為單座式和雙座式；按閥瓣的位置不同可分為正作用式和反作用式

自力式減壓閥的工作由閥后壓力進行控制。當(dāng)壓力感應(yīng)器檢測到閥門壓力指示升高時，減壓閥閥門開度減??；當(dāng)檢測到減壓閥后壓力減小，減壓閥閥門開度增大，以滿足控制要求。

減壓閥是一種利用介質(zhì)自身能量來調(diào)節(jié)與控制管路壓力的智能型閥門。用于生活給水、消防給水及其他工業(yè)給水系統(tǒng),通過調(diào)節(jié)閥減壓導(dǎo)閥,即可調(diào)節(jié)主閥的出口壓力。出口壓力不因進口壓力、進口流量的變化而變化，安全可靠地將出口壓力維持在設(shè)定植上，并可根據(jù)需要調(diào)節(jié)設(shè)定值達(dá)到減壓的目的。該閥減壓精確，性能穩(wěn)定、安全可靠、安裝調(diào)節(jié)方便，使用壽命長。

減壓閥是一種自動降低管路工作壓力的專門裝置，它可將閥前管路較高的水壓減少至閥后管路所需的水平。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。
