力士樂直動(dòng)式溢流閥DBDH6G1A/50
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)開啟）。

壓力控制按用途分為溢流閥﹑減壓閥和順序閥。⑴溢流閥：能控制液壓系統(tǒng)在達(dá)到調(diào)定壓力時(shí)保持恒定狀態(tài)。用於過載保護(hù)的溢流閥稱為安全閥。當(dāng)系統(tǒng)發(fā)生故障，壓力升高到可能造成破壞的限定值時(shí)，閥口會(huì)打開而溢流，以保證系統(tǒng)的安全。⑵減壓閥：能控制分支回路得到比主回路油壓低的穩(wěn)定壓力。減壓閥按它所控制的壓力功能不同，又可分為定值減壓閥（輸出壓力為恒定值）﹑定差減壓閥（輸入與輸出壓力差為定值）和定比減壓閥（輸入與輸出壓力間保持一定的比例）。⑶順序閥：能使一個(gè)執(zhí)行元件（如液壓缸﹑液壓馬達(dá)等）動(dòng)作以后，再按順序使其他執(zhí)行元件動(dòng)作。油泵產(chǎn)生的壓力先推動(dòng)液壓缸1運(yùn)動(dòng)，同時(shí)通過順序閥的進(jìn)油口作用在面積A 上，當(dāng)液壓缸1運(yùn)動(dòng)完全成后，壓力升高，作用在面積A 的向上推力大於彈簧的調(diào)定值后，閥芯上升使進(jìn)油口與出油口相通，使液壓缸2運(yùn)動(dòng)。

力士樂直動(dòng)式溢流閥DBDH6G1A/50
定流量閥和橫流量調(diào)節(jié)閥都是變阻力設(shè)備，它們是以流體的差壓作為動(dòng)力，并根據(jù)系統(tǒng)工況（差壓）變化，自動(dòng)改變阻力系數(shù)，保持流量閥和橫流量的恒定，通過恒定各個(gè)支路的流量來實(shí)現(xiàn)整個(gè)系統(tǒng)流量的均衡輸配，消除冷熱不均的現(xiàn)象。在總流量足夠的條件下，各個(gè)支路的流量變化不會(huì)互相影響，系統(tǒng)比較穩(wěn)定。
