Abstract

A topology design method for coupling valve ports throttling structure of multi-way directional valves is proposed to solve the coupling problem between the valve ports caused by flow distribution characteristic in the process of reversing transition. The throttling structures of coupling valve ports are classified into semicircle groove

U-shaped groove

round hole groove and so on

and formed by different parameterized combinations of these structures. A model to describe the function between work flow of multi-way directional valve and variables of its coupling valve ports throttling groove structure is constructed. The work flow in the process of reversing transition of multiple directional control valve is set as an evaluation target based on the validation of three-dimensional fluid dynamic analysis of multi-way directional valve and its dynamic characteristics results of test bench. Then a particle swarm algorithm is used to solve the topology design problem of valve ports throttling groove structure

so that a good agreement between the response of coupling valve throttling structure and the throttling characteristic in the process of reversing transition is realized. The results show that the method has a reference value of engineering for the topology design of coupling valve ports throttling structure in meeting the requirements of reversing transition characteristics of multi-way directional valves.
