德國(guó)Rexroth力士樂(lè)溢流閥產(chǎn)品說(shuō)明:
溢流閥是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,穩(wěn)壓,系統(tǒng)卸荷和安全保護(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(huì)使流量需求減小。此時(shí)溢流閥開(kāi)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(dòng)開(kāi)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(yùn)動(dòng)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(dāng)電磁鐵通電時(shí),溢流閥的遙控口通油箱,此時(shí)液壓泵卸荷。溢流閥此時(shí)作為卸荷閥使用。
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(guò)規(guī)定的極限(系統(tǒng)壓力超過(guò)調(diào)定壓力)時(shí)開(kāi)啟溢流,進(jìn)行過(guò)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(jí)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(dòng)型溢流閥 。2、先導(dǎo)式溢流閥。
對(duì)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(dòng)作靈敏,過(guò)載能力大,噪聲小。
