SMC小型集裝式減壓閥導(dǎo)致?lián)醢?與噴嘴4之間的間距加大，空氣減壓閥G室和D室的氣壓下降。由于B室壓力增高，D室壓力下降，膜片15在壓差的作用下向上移動，使主閥口減小，輸出壓力下降，直到穩(wěn)定到調(diào)定壓力上。此外，在輸入壓力上升時，E室壓力和F室瞬時壓力也上升，膜片3在上下差壓的作用下上移，就會使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，使進(jìn)氣閥口8開大或關(guān)小、提高了對閥芯控制的靈敏度，即提高了穩(wěn)壓精度。 先導(dǎo)式減壓閥所用的調(diào)壓氣體，是由小型的直動式減壓閥供給的。若把小型直動式減壓閥裝在閥體內(nèi)部，則稱為內(nèi)部先導(dǎo)式減壓閥；若將小型直動式減壓閥裝在主閥體外部，則稱為外部先導(dǎo)式減壓閥。 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），圖14—2所示為內(nèi)部先導(dǎo)式減壓閥的結(jié)構(gòu)圖，與直動式減壓閥相比，該閥增加了由噴嘴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，其工作原理與直動式相同。在主閥體外部還有一個小型直動式減壓閥（圖中末示出），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、危險處、調(diào)壓困難的場合。
