Therefore, the correct analysis and design of reciprocating pump valves are to ensure efficient
safe and reliable work and to extend the pump life cycle of one of the important elements. Firstly
some elementary knowledge of reciprocating pump and the structural characteristics of pumps and
valves are introduced simply, as well as the classification and movement of the parameters and so
on. Then, according to design requirement, the force applied to reciprocating pump valves was
initially analyzed, then the three-dimensional model and motion Simulation of reciprocating
pump valves with engineering software Pro/E Wildfire were completed, finally the finite element
method was used, and the model to the finite element analysis software was imported to analyze
its stress and identify the deficiencies. The basis of optimizing the final design is provided.
Key words: reciprocating pump; pump valve; finite element method
