產(chǎn)品詳情
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)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)。
