| Abstract: | By means of static theory analysis, structure optimization design and dynamic simulation simulation, a explosion-proof load sensitive ratio multi-way valve is designed.According to the hydraulic principle of the Explosion-proof load sensitive ratio multi-way valve and load sensitive system,the design requirements of the explosion-proof load sensitive radio multi-way switch valve group are put forward, and the hydraulic schematic diagram of the two-link explosion-proof group is designed. The static theory analysis was used to study the flow characteristics of the valve group;Explosion-proof load sensitive ratio two-way multi-valve group adopts the combination of plate valve and plug valve to optimize the structure layout，complete the structure design of the explosion-proof load sensitive multi-directional valve group; Based on AMESim,the simulation model of the explosion-proof load sensitive ratio multi-way valve is established and dynamic simulation is carried out. The results show that the flow ratio characteristics and pressure flow characteristics of the new type explosion-proof load sensitive multi-directional valve group meet the design requirements of load sensitive multi-way valve. |
