Research on Green Design of Valve Products Based on Response Surface Method

In order to realize the green design requirement of 550 mm gate valve in a valve system of an enterprise, the response surface method was used to optimize the body structure by single factor objective. Body wall thickness, height of stiffener, and thickness of stiffener as the objective factor, gate parameterized model is set up, using the finite element analysis software to optimize the former body strength that is numerically simulated, and based on DOE target optimization design for the parameters of optimized body coupling analysis, get the body by the maximum equivalent stress is 103 MPa. The results show that the strength of the improved valve body can apply to the requirements of the actual working condition, and the consumption of raw materials of the product is greatly reduced compared with the original design, which meets the requirements of the green design of valve products.
