液压高频换向阀的设计

Design of hydraulic high frequency directional valveAbstractLinear friction welding technology is a relatively advanced solid-phaseconnection technology at home and abroad.One of the key parts of the weldingmachine is the reciprocating vibration moving parts.The comprehensive performanceof hydraulic reciprocating vibration is particularly excellent.The high frequencydirectional valve is a key component to realize hydraulic reciprocating vibration.There are many designs of directional valves on the market,but they lack newideas.There are few cases that can be referenced,and the type of valve has not changedmuch.In order to solve the problem of hydraulic high-frequency reversing valvereversing,I consulted relevant literature and listed various types of reversingvalves,and gradually eliminated them,in order to select and optimize the design ideaand direction of the reversing valve.The thesis is to optimize and improve on the basis of the original hydraulichigh-frequency directional valve design.Which refers to the movement principle ofthe revolver weapon Gatling,after analyzing it,disassemble and combine thecomponents of Gatling,optimize the original design ideas,and design a morereasonable hydraulic high-frequency commutation valveKeywords:linear friction welding:high frequency directional valve
