Abstract

Disclosed i s an electric-control multimode steering valve. The steering valve comprises: a flow distributing and collecting valve (Y), a first electromagnetic exchange valve (Yl), and a second electromagnetic exchange valve (Y2). A valve body comprises four groups of paired valve oil ports. First oil ports of the first electromagnetic exchange valve (Yl) and the second electromagnetic exchange valve (Y2) are respectively i n communication with a first group of valve oil ports (PR , PL ) of the valve body. Second oil ports of the first electromagnetic exchange valve (Yl) and the second electromagnetic exchange valve (Y2) are respectively in communication with a second group of valve oil ports (Al, Bl) of the valve body. A third oil port of the first electromagnetic exchange valve (Yl) i s in communication with a flow collecting port of the flow distributing and collecting valve (Y). A first flow distributing port of the flow distributing and collecting valve (Y) and a third oil port of the second electromagnetic exchange valve (Y2) are respectively in communication with a third group of valve oil ports (A2, B2) of the valve body. A second flow distributing port of the flow distributing and collecting valve (Y) and the third oil port of the second exchange valve (Y2) are respectively i n communication with a fourth group of valve oil ports (A3, B3) of the valve body. Further disclosed are a steering hydraulic control system and a wheel type crane. The steering valve can implement multimode steering of engineering vehicles, and the working i s reliable and the cost i s low.
