Description

Multi-channel valve capable of being selected and twisted by oneself

Technical Field

The invention relates to a multi-channel valve, in particular to a self-selecting mixing and twisting multi-channel valve.

Multi-channel valves are widely used. At present, most of multi-channel valves on the market are controlled by hydraulic pressure, the distribution or switching stability, rapidity and reliability of hydraulic energy supply between a steering loop and other working loops in a hydraulic system of a walking machine directly determine the comfort, control characteristics, energy conservation and reliability of operation of a main engine, at present, a valve core valve port of a hydraulic steering priority valve adopts a non-full-periphery opening, namely a throttling groove structure under a small opening and a full-periphery opening form under a large opening, the structure has a valve port area gradient mutation, thus the flow mutation is caused, steering hydraulic impact is easy to be caused, the problems of system vibration, noise, system power consumption and the like are solved, the motion damping in the steering process of the valve core is ensured only by arranging a single damping hole form, the asymmetry of the bidirectional motion of the valve core is not completely matched with that of the valve core, in addition, the existing hydraulic steering priority valve only considers one working form of static signal type or dynamic signal type, the problem of easy modification of the structure between the two valve core valve is not considered, and the universality of elements is reduced.

In addition, as the number of channels increases, the structure tends to be more complex, and the control of the overall structure can be realized only by the linkage structure.

Comparison document: cn201711036781.X provides a multi-way valve with a priority valve in the head-on, which is too complex in structure and which is not too useful for situations where precise regulation is not required.
