For a certain type of needle valve coupler under the working condition, the high pressure oil is easy to leak from the contact end face of the needle valve body and the needle spring seat, so the Solidworks software was used to establish the overall 3D model of the needle valve coupler and design different micro concave structures. Then use Ansys simulation analysis software to simulate the working conditions to statically simulate the micro-concave structure on the needle body. According to the simulation analysis results, the micro-concave structure on the needle valve body was optimized, so that the high-pressure oil leakage problem was improved.
