CONSTRUCTIONAL-FUNCTIONAL ANALYSIS AND GRAPHIC DESIGN OF ELECTRO-HYDRAULIC VALVE DISTRIBUTOR

Abstract

Among the machines which distribute fluid discharge in hydrostatic installations, valve distributors are the most important and differ in terms of a series of criteria related to the number of grooves, the distribution sketch, the nature of the switchboard etc. A valve distributor is comprised of a fixed part (the valve body), a mobile part (valve) and actuator elements. The operation of this type of distributors is based on the translation and shut down of the valve in the body in certain positions. These positions are fixed and the correspondence with certain paths from the body is specific for each type of distributor. This correspondence determines the transfer of the fluid according to the distribution sketch. The work presents the construction-functional analysis and CAD design in the CATIA graphic design environment of a basic distributor component – the valve, CAE analysis, with its finite element, as well as CAM simulation with the help of Sinumerik 840D software and system control of machining operations and phases by cutting the valve.
