意大利ATOS溢流閥一種液壓壓力控制閥,在液壓設(shè)備中主要起定壓溢流作用和安全保護(hù)作用。定壓溢流作用：在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中，定量泵提供的是恒定流量。當(dāng)系統(tǒng)壓力增大時(shí)，會使流量需求減小。此時(shí)溢流閥開啟，使多余流量溢回油箱，保證溢流閥進(jìn)口壓力，即泵出口壓力恒定（閥口常隨壓力波動開啟）。安全保護(hù)作用：系統(tǒng)正常工作時(shí)，閥門關(guān)閉。只有負(fù)載超過規(guī)定的極限（系統(tǒng)壓力超過調(diào)定壓力）時(shí)開啟溢流，進(jìn)行過載保護(hù)，使系統(tǒng)壓力不再增加（通常使溢流閥的調(diào)定壓力比系統(tǒng)zui高工作壓力高10%～20%）。實(shí)際應(yīng)用中一般有：作卸荷閥用，作遠(yuǎn)程調(diào)壓閥，作高低壓多級控制閥，作順序閥，用于產(chǎn)生背壓（串在回油路上）。溢流閥一般有兩種結(jié)構(gòu)：1、直動型溢流閥 。2、先導(dǎo)型溢流閥.溢流閥的主要要求：調(diào)壓范圍大，調(diào)壓偏差小，壓力振擺小，動作靈敏，過載能力大，噪聲小。ATOS溢流閥型號：AGMZA-A-10/250/M AGMZA-A-10/250/M先導(dǎo)式溢流閥 AGMZA-A-10/250/M比例閥 AGMZA-A-10/250/PA-M AGMZA-A-10/250/PA-M先導(dǎo)式溢流閥 AGMZA-A-10/250/PA-M比例閥
