摘　　要：工程机械多路阀阀芯、阀体切削加工后残余应力重新释放和分布,形成微小变形,是卡阀的主要因素。我国工程机械液压件行业都不做消除残余应力处理。该文简要介绍了残余应力形成及消除办法,对解决液压阀卡阀问题提出了新思路。The main factor of stuck valve is that engineering machinery＇s multi valve core and valve body by machining lead to the residual stress release and distribution,so small deformation was caused.Engineering machinery hydraulic parts have been not eliminated the residual stress in china industry.The formation of residual stress and it＇ s elimination methods were introduced briefly in paper.New ideas with solving the hydraulic stuck valve was suggested.
