The invention discloses a special valve group with automatic and manual isolation bypass functions for a tilt cylinder type steering engine, which comprises two groups of control oil ways and two groups of main oil ways which are arranged in parallel, and each oil way is formed by sequentially connecting a special valve block, a one-way valve, a special electro-hydraulic directional control valve, an electromagnetic ball valve and a manual ball valve; the electro-hydraulic reversing valve is a two-position four-way plate type special electro-hydraulic valve and is installed on the general valve block through threaded connection, and the one-way valve, the electromagnetic ball valve, the manual ball valve and the general valve block are inserted into the valve body through threads to be connected. The manual ball valves are connected to the two side faces of the valve body through the connectors, meanwhile, through the modularized and integrated optimization design, the weight and the size of the product are reduced by about one fourth, the light weight effect is achieved, and installation and use are more convenient. Due to the fact that the pipe hole of the valve block is optimized, noise and vibration are reduced.

    本发明公开了的摆缸式舵机专用具自动和手动隔离旁通功能阀组,包括并联设置的两组控制油路,和两组主油路,各油路由依次连接专用阀块、单向阀、专用电液换向阀,电磁球阀,手动球阀;电液换向阀为二位四通板式专用电液阀,其通过螺纹连接安装在通用阀块上面,单向阀、电磁球阀、手动球阀与通用阀体通过螺纹插入阀体连接;手动球阀通过接头连接在阀体的两侧面,同时通过模块化,集成化的优化设计,使产品的重量和体积减少了约四分之一,达到了轻量化的效果,安装使用更加方便。由于阀块的管孔进行了优化,减少了噪音和振动。
