The embodiment of the invention relates to a safety guide pile-up valve and a hydraulic interconnection suspension device. In the safety guide pile-up valve, two external oil ports are formed in the outer side of a valve seat and used for being connected with two pipelines of a hydraulic interconnection suspension respectively; two guide valve cavities are formed in the valve seat; a limiting step is arranged in the middle of the guide valve cavity, a first cavity is formed in one side, and a second cavity is formed in the other side; the two safety guide valves are reversely and horizontally arranged in the two guide valve cavities; each safety guide valve comprises a fixed valve element, a movable valve element, a spring, a bearing block and a branch end nut. When the hydraulic interconnection suspension is in a normal working state, the pressure difference between the two sides of the bearing block enables the spring to be compressed, and the safety guide valve is in a closed state and used for pressure maintaining and leakage prevention of two pipelines of the hydraulic interconnection suspension. When the pipelines of the hydraulic interconnection suspension are in a leakage state, the fixed valve element and the movable valve element are in a staggered communication state, and the safety guide valve is in a conducting state, so that oil pressure unloading of the two pipelines of the hydraulic interconnection suspension is achieved.
本发明实施例涉及一种安全导向集成阀及液压互联悬挂装置。安全导向集成阀中,阀座外侧开设两个外接油口用于分别连接液压互联悬架的两路管路;阀座内设有置于两个导向阀腔;导向阀腔的中部具有限位台阶,一侧为第一腔室,另一侧为第二腔室;两个安全导向阀反向水平设置于两个导向阀腔中;每个安全导向阀包括:固定阀芯、移动阀芯、弹簧、承载块和支路端螺母;在液压互联悬架正常工作状态下,承载块两侧的压力差使得弹簧被压缩,安全导向阀处于关闭状态,用以液压互联悬架的两路管路的保压和防泄漏;在液压互联悬架的管路发生泄漏的状态下,固定阀芯与移动阀芯处于错位连通状态,安全导向阀处于导通状态,用以液压互联悬架的两路管路油压卸荷。
