力士樂dbda 6 k1x/315溢流閥特點(diǎn)
rexroth溢流閥db和dbw型閥門是插入結(jié)構(gòu)的先導(dǎo)型溢流閥，用來限制系統(tǒng)壓力(db)，或者限制(dbw只有螺紋連接)系統(tǒng)的壓力。此閥組主要包括閥體和溢流閥的插入元件。管路內(nèi)的壓力作用在閥芯上，通過節(jié)流孔作用于球閥芯。管路內(nèi)的壓力超過了彈簧所設(shè)定的壓力值，球閥芯克服了彈力開啟。這時(shí)從油口流出的油液通過節(jié)流孔流入彈簧腔，由外部控制通道引導(dǎo)到油箱內(nèi)。當(dāng)閥芯內(nèi)高壓流體處于平衡狀態(tài)時(shí)，油液通過a口流入b口，同時(shí)保持設(shè)定的工作壓力恒定。dbw型溢流閥(只有螺紋聯(lián)接)的功能與db型一樣。利用頂向閥可以控制主閥的卸荷。
1.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)溢流閥開啟,使多余流量溢回油箱,保證溢流閥進(jìn)...
2.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。
3.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。
