單向閥的工作原理基于流體的壓力和?彈簧的彈力之間的平衡。它主要由閥體、閥芯和彈簧組成，閥體內(nèi)部設(shè)有通道，與進(jìn)出口相連通。在沒有外部作用力的情況下，單向閥的閥芯會(huì)停留在關(guān)閉位置，阻止液體從進(jìn)口流向出口。當(dāng)液體從進(jìn)口流入時(shí)，液體壓力作用于閥芯，克服彈簧的阻力，推動(dòng)閥芯移向打開位置。當(dāng)液體通過單向閥時(shí)，彈簧會(huì)逐漸恢復(fù)彈性，試圖將閥芯拉回關(guān)閉位置，但由于流體的慣性力和出口壓力的作用，閥芯不會(huì)立即回到關(guān)閉位置，因此液體可以持續(xù)流動(dòng)。當(dāng)液體從出口流出時(shí)，出口壓力降低，由于彈簧的作用力和液體流出的速度較慢，閥芯會(huì)迅速回到關(guān)閉位置，阻止液體的反向流動(dòng)。?
