- ÍtemDiseño funcionamiento y aplicabilidad de una valvula controladora de flujo de cuerpo biseccional y triple sistema de accionamiento integrado(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Escalante Niño, Carlos Fernando; Villalba, Jorge ArmandoThe management of working fluids in industries such as hydrocarbons, water treatments, oil production, refineries and among others, is a task that involves the design, calculation and construction of complex pipeline networks with control and instrumentation elements. integrated that seek to give security and meaning to the process itself. The selection of these components starts from the idea of controlling the multiple variables of these fluids in motion from the effective interaction of these elements and the functional compression of them. However, the marked diversification of these elements leads to the design and budget of a project specific problems that range from the cost of a very varied stock of valves, spare parts and parts, to the factory restrictions that a valve has by construction and limit the range of its applicability. Thinking about how to minimize these problems in a practical and viable way, this thesis develops a multifunctional valve model that integrates 3 typical models of different operation into one, considering and attending to the regulatory guidelines for these equipment and real border conditions on the which these valves work on. In the first stay of this document, a conceptual environment was considered, which alludes to basic concepts of theory and calculation that allow us to understand the basis of the design and conception of the proposed model in its aspects of operation and physical form. Later, the valve design was developed in a CAD work environment, supported by the formulation of calculations and selection of materials for certain base components of the model, as well as the reference to technical parameters that are necessary to understand in order to make logical sense of certain internal valve systems and their effective selection. The simulation and validation of the model is made from specific tests of static pressure, by dynamic regime, vorticity in the CAE-CFD work environment, from which the results obtained were analyzed and the feasibility of the internal geometry and the reliability of the design concepts formulated in the previous part of the document. Similarly, the evaluation of these results allowed inferring elements of judgment in the valve operation recommendations and their comparison with commercial models of the same level. Finally, a commercial evaluation of the model was carried out in order to estimate economic costs as well as its technical feasibility
