Development of a sequential hydraulic valve

Sekvenčni hidravlični ventili se uporabljajo za vzporedno ali zaporedno krmiljenje hidravličnih sestavin. Na podlagi podanih vhodnih parametrov smo dimenzionirali in nato s pomočjo programa Solidworks izrisali 3D modele dveh prototipov ventila, ki sta bila nato izdelana. Na izdelanih prototipih smo izvedli meritve padcev tlaka v ventilu in določili ustrezna prednapetja vzmeti, da ventil zagotavlja vzporedno krmiljenje hidravličnih valjev. Med seboj smo primerjali vse koncepte in izdelane prototipe ventilov ter na podlagi dobljenih izračunov in meritev predlagali rešitve za optimizacijo izdelka.Sequential hydraulic valves are used for parallel or sequential control of hydraulic components. Based on the given input parameters, we dimensioned two prototype valves and drew their 3D-models using the Solidworks program. After that, the prototype valves were constructed. We carried out the measurements of valve pressure drops on the constructed prototypes and determined the appropriate spring pre-stressing that allowed the valve to provide parallel control of hydraulic cylinders. We compared all the concepts and valve prototypes and, based on the measurements and calculations obtained, proposed solutions for product optimization
