The invention discloses an integrated oil tank isolation valve. The integrated oil tank isolation valve comprises a shell, an integrated electromagnetic valve, a negative pressure valve assembly, a positive pressure valve assembly and a plug. A first cavity and a second cavity are sequentially formed in the shell from top to bottom, and a vent plate is arranged between the first cavity and the second cavity; a center vent hole is formed in the center of the vent plate and matched with the positive pressure valve assembly, a first-stage opening vent hole is formed in the positive pressure valveassembly, and a plurality of second-stage opening vent holes are further formed in a vent partition plate and evenly distributed in the periphery of the center vent hole; and the integrated electromagnetic valve located above the shell is pressed downwards into the shell. The integrated oil tank isolation valve is reasonable in structural design, fewer in component number and more compact in structure, the mounting steps, the number of tools and the risk of neglected mounting or wrong mounting are reduced, the phenomenon that flow and pressure change sharply during opening and closing is avoided, stable pressure change is ensured, secondary opening is achieved, and the application prospect is wide.

    一种集成式油箱隔离阀,包括壳体、集成电磁阀、负压阀组件、正压阀组件、堵头;所述壳体内部从上至下依次设置有第一腔体和第二腔体并且第一腔体和第二腔体之间设置有通气板;所述通气板中心处开设有中心通气孔,所述中心通气孔与正压阀组件相配合,所述正压阀组件开设有一级开启通气孔,所述通气隔板上还开设有若干个二级开启通气孔并且均匀布置于中心通气孔外周;位于壳体上方的所述集成电磁阀向下压入壳体中。本发明所述的集成式油箱隔离阀,结构设计合理,部件数量更少,结构更加紧凑,减少了安装步骤、工装数量、漏装或错装风险,解决了开启、关闭时流量、压力急剧变化的现象,确保压力平稳变化,实现了二级开启,应用前景广泛。
