Abstract

The article deals with the design of a perspective throttle valve with an elastic tubular element designed to reduce the vibration and noise of hydraulic systems, which are subject to increased requirements for vibro-acoustic characteristics. The analysis of known similar devices is carried out and the design of the valve-throttle is proved. A detailed analysis of the deformed state of the elastic tubular element is performed and the relationship between the deformations of this element and the hydraulic parameters of the working medium in the flowing part of the valve is shown. The experimental flow characteristics of the valve under study are analyzed, the analysis of which has made it possible to identify the parts of the characteristics at which the constant flow rate remains constant when the pressure drop across the valve changes. The substantiation of this feature of the hydraulic characteristics of a valve with an elastic element is given. The ways of further research directions of the prospective valve are shown.
