Constructive-Functional Analysis and Calculation of Flow Control Valves

Abstract

In hydraulic installations, the flow regulation is performed in two ways: volume regulation (by variable flow pump) and resistive regulation, with the help of the flow regulation equipment. The second variant, although with lower energy efficiency, is most often preferred in small and medium power installations, due to the constructional simplicity and easy maneuverability of the equipment, as well as the ease of performing operation control. The paper presents the construction of the most important devices for resistive flow regulation, the mode of operation and installation in the structure of the systems, as well as certain elements of their calculation.
