Rexroth力士樂先導式比例方向閥
(力士樂rexroth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。
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。
溢流閥的作用
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)壓力增加(通常使溢流閥的調(diào)定壓力比系統(tǒng)工作壓力高10%~20%)。
