DBDS10P1X/50V力士樂DBD直動式溢流閥

?溢流閥是一種液壓壓力控制閥。在液壓設備中主要起定壓溢流作用，穩(wěn)壓，系統(tǒng)卸荷和安全保護作用。 　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。當系統(tǒng)壓力增大時，會使流量需求減小。此時溢流閥開啟，使多余流量溢回油箱，保證溢流閥進口壓力，即泵出口壓力恒定（閥口常隨壓力波動開啟）。 　　

穩(wěn)壓作用：溢流閥串聯(lián)在回油路上，溢流閥產(chǎn)生背壓運動部件平穩(wěn)性增加。 　　

系統(tǒng)卸荷作用：在溢流閥的遙控口串接溢小流量的電磁閥，當電磁鐵通電時，溢流閥的遙控口通油箱，此時液壓泵卸荷。溢流閥此時作為卸荷閥使用。 　　

安全保護作用：系統(tǒng)正常工作時，閥門關閉。只有負載超過規(guī)定的極限（系統(tǒng)壓力超過調(diào)定壓力）時開啟溢流，進行過載保護，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)最高工作壓力高10%～20%）。 　　

實際應用中一般有：作卸荷閥用，作遠程調(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構：1、直動型溢流閥 。2、先導型溢流閥。 　　

對溢流閥的主要要求：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。DBDS10K1X/315-220
