減壓閥

直動(dòng)式減壓閥所示為直動(dòng)式帶溢流閥的減壓閥(簡稱溢流減壓閥)的結(jié)構(gòu)圖。

溢流減壓閥是靠進(jìn)氣口的節(jié)流作用減壓，靠膜片上力的平衡作用和溢流孔的溢流作用穩(wěn)壓；調(diào)節(jié)彈簧即可使輸出壓力在一定范圍內(nèi)改變。為防止以上溢流式減壓閥徘出少量氣體對(duì)周圍環(huán)境的污染，可采用不帶溢流閥的減壓閥(即普通減壓閥)。

先導(dǎo)式

先導(dǎo)式減壓閥

內(nèi)部先導(dǎo)式減壓閥當(dāng)減壓閥的輸出壓力較高或通徑較大時(shí)，用調(diào)壓彈簧直接調(diào)壓，則彈簧剛度必然過大，流量變化時(shí)，輸出壓力波動(dòng)較大，閥的結(jié)構(gòu)尺寸也將加大。為了克服這些缺點(diǎn)，可采用先導(dǎo)式減壓閥。先導(dǎo)式減壓閥的工作原理與直動(dòng)式的基本相同。先導(dǎo)式減壓閥所用的調(diào)壓氣體，是由小型的直動(dòng)式減壓閥供給的。若把小型直動(dòng)式減壓閥裝在閥體內(nèi)部，則稱為內(nèi)部先導(dǎo)式減壓閥；若將小型直動(dòng)式減壓閥裝在主閥體外部，則稱為外部先導(dǎo)式減壓閥。與直動(dòng)式減壓閥相比，增加了由噴嘴4、擋板3、固定節(jié)流孔9及氣室B所組成的噴嘴擋板放大環(huán)節(jié)。當(dāng)噴嘴與擋板之間的距離發(fā)生微小變化時(shí)，就會(huì)使B室中的壓力發(fā)生根明顯的變化，從而引起膜片10有較大的位移，去控制閥芯6的上下移動(dòng)，使進(jìn)氣閥口8開大或關(guān)小、提高了對(duì)閥芯控制的靈敏度，即提高了穩(wěn)壓精度。

在主閥體外部還有一個(gè)小型直動(dòng)式減壓閥由它來控制主閥。此類閥適于通徑在20mm以上，遠(yuǎn)距離(30m以內(nèi))、高處、危險(xiǎn)處、調(diào)壓困難的場合。
