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是壓縮空氣，其特點是動作快，但速度不易控

制，當載荷變化較大時，容易產生“爬行”或“自走”現象；而液壓缸采用的工作介質是通常認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，

當載荷變化較大時，采用措施得當，一般不會產生“爬行”和“自走”現象。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，單向閥關閉，油只能通過節(jié)流

閥流入液壓缸右腔及油杯內，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)流閥閥口關小，液壓缸左腔排油受阻，兩活塞

運動速度會減慢。這樣，調節(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是氣缸中壓縮空氣產生的力（推力或拉力）與液壓缸中

油的阻尼力之差。

產品介紹SMC內部先導式減壓閥@smc中國有限公司

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

即使在大或者小流量時它也應該能夠對正作用或者反作用控制信號做出響應。這些閥門應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進口先導式減壓閥是采用控制閥體內的啟閉件的開度來調節(jié)介質的流量，將介質的壓力降低，同時借助閥后壓力的作用調節(jié)啟閉件的開度，使閥后壓力保持在一定范圍內，在進口壓力不斷變化的情況下，保持出口壓力在設定的范圍內，保護其后的生活生產器具。本類閥門在管道中一般應當水平安裝。

是氣動調節(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，以便于調節(jié)閥能夠獲得穩(wěn)定的氣源動力用于調節(jié)控制。按結構形式可分為膜片式、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。當壓力感應器檢測到閥門壓力指示升高時，減壓閥閥門開度減?。划敊z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自身能量來調節(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,通過調節(jié)閥減壓導閥,即可調節(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定植上，并可根據需要調節(jié)設定值達到減壓的目的。該閥減壓精確，性能穩(wěn)定、安全可靠、安裝調節(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、城市給水管網水壓過高的區(qū)域、礦井及其他場合，以保證給水系統中各用水點獲得適當的服務水壓和流量。
