自動(dòng)再循環(huán)閥可用于給其中的壓力可能升至超過系統(tǒng)壓的輔助系統(tǒng)提供補(bǔ)給的管路上。自動(dòng)再循環(huán)閥主要可分為旋啟式自動(dòng)再循環(huán)閥（依重心旋轉(zhuǎn)）與升降式自動(dòng)再循環(huán)閥（沿軸線移動(dòng)）。自動(dòng)再循環(huán)閥這種類型的閥門的作用是只允許介質(zhì)向一個(gè)方向流動(dòng)，而且阻止反方向流動(dòng)。通常這種閥門是自動(dòng)工作的，在一個(gè)方向流動(dòng)的流體壓力作用下，閥瓣打開；流體反方向流動(dòng)時(shí)，由流體壓力和閥瓣的自重合閥瓣作用于閥座，從而切斷流動(dòng)。其中自動(dòng)再循環(huán)閥就屬于這種類型的閥門。自動(dòng)再循環(huán)閥結(jié)構(gòu)簡(jiǎn)略、體積小、重量輕，只由少量幾個(gè)零件組成。江蘇三通回流閥報(bào)價(jià)多少錢自動(dòng)再循環(huán)閥可將閥前管路較高的水壓減少至閥后管路所需的水平.</p><div
