SMC AR系列減壓閥穩(wěn)壓原理
參見上面SMC AR平衡式直動(dòng)式減壓閥結(jié)構(gòu)原理圖。
若進(jìn)口壓力有波動(dòng),譬如壓力瞬時(shí)升高,則出口壓力也隨之升高。作用在膜片上的推力增大,膜片上移,向上壓縮彈簧,從膜片組件中間的溢流孔有瞬時(shí)溢流。并靠復(fù)位彈簧及氣壓力作用,使閥桿上移,閥門開度減小,節(jié)流作用增大,使出口壓力回降,直至達(dá)到新的平衡為止。重新平衡后的出口壓力又基本上恢復(fù)至原值。
如進(jìn)口壓力不變,輸出流量變化,使出口壓力發(fā)生波動(dòng)(增高或降低)時(shí),依靠溢流孔的溢流作用和膜片上力的平衡作用推動(dòng)閥桿,仍能起穩(wěn)壓作用。當(dāng)輸出流量為零時(shí),出口氣壓力通過反饋管進(jìn)入膜片下腔,推動(dòng)膜片上移,復(fù)位彈簧力推動(dòng)閥桿上移,閥芯關(guān)閉,保持出口氣壓力一定。當(dāng)輸出流量很大時(shí),高速流使反饋管處靜壓下降,即膜片下腔壓力下降,閥門開度加大,仍能保持膜片上的力平衡。
