Optimización mediante el rediseño de la válvula de control con accionamiento neumático para la máquina dosificadora de líquidos viscosos de pistón único regulable de 100cc a 1000cc con alimentadora por gravedad.

Abstract

This document details the design and construction of a dosing machine for viscous liquids with a capacity of 100cc to 1000cc in Stainless Steel 304 food grade, in order to improve the accuracy of the dosing of the working fluid, the selection of the appropriate type of valve for handling fluids with high viscosity to achieve an accuracy of at least 97% is performed, For this purpose, a 3-way 2-position ball valve is designed using SOLIDWORKS software. For the validation of the generated design, flow behavior simulations are performed using ANSYS software with the FLUENT module for Tomato Sauce, Body Cream and Shampoo, in search of a laminar flow at the time of fluid dosing. After the validation of the generated valve design, the G codes were generated for machining on a 3-axis CNC lathe owned by the author of this thesis using SOLIDWORKS-CAM and CIMCO Edit. 8 software for the correction of the generated codes, proceeding to the machining of the valve applying slow advances and construction of the machine looking for good surface finishes. Finally, after the process of testing the operation of the machine and dosing accuracy of different volumes of work of the control valve was achieved to obtain an error of less than 3% fulfilling the objective of optimizing the efficiency of 3-way 2-positions control valve.
