充液閥主要由控制活塞、缸體、閥體、閥座、主閥芯、卸荷閩等組成。根據需要，我們設計有帶預卸荷閥和不帶預卸荷閥的兩種充液閥。如果采用系統(tǒng)卸壓．即系統(tǒng)中設置了卸荷回路，則采用不帶預卸荷閥的充液閥，這種情況尤其適用干大型液壓機。Dg50～Dg125規(guī)格的充液閥的主閥芯與閥桿做成一體，即采用整體構造；Dg150～Dg350規(guī)格的充液閥的主閥芯與閥桿采用分體結構。

2防松措施

參見圖l充液閥結構原理圖，a處防松采用GB858—76圓螺母用止動墊圈；b處安裝螺釘的防松采用c船54一鼴單耳止動墊圈；c處主閥芯與閥桿之問的防松采用左旋、右旋螺母擰緊后點焊；d處卸荷閥蓋的防松采用了彈簧墊圈及帶孔螺栓用鐵絲串聯鎖緊。

3主悶計算

已知當量通徑Dg(m)，主闊開啟行程h(m),閥口錐角2α =120。則：

當量通流面積Ag=πDg 2／4。主閥口直徑。

4控制活塞計算

控制活塞直徑應盡可能小，但必須滿足兩個條件：

1)當主缸油壓為最大工作壓力(p=2.5×107Pa)和控制油壓為最小油壓(pc=1.5×106Pa)時，控制活塞應能將充液閥中的卸載閥打開，即：?

式中：dv-卸載閥口直徑(m)；

Dc-控制活塞直徑(m)。

(2)主缸活塞回程時充液閥的主閥芯不關閉，即：
