Throttling intensification of the flow part of flow control regulators

  • Published:
Atomic Energy Aims and scope

The objective of this article is to validate the possibility of increasing the effectiveness of flow-part throttling to produce intensified flow control regulators which are stable and noise-, vibration-free in their entire operating range while preserving the required parameters and lowering the flow velocity. The problems arising during the operation of flow regulators and the reason why such problems appear are described. A concept is proposed for intensifying the throttling of the flow part of flow regulators, making it possible to eliminate the undesirable phenomena arising during operation of regulators: vibration, cavitation, noise and instability. The experimental coefficients of hydraulic resistance of the throttling adjustment windows are presented. The possibility of intensifying the flow parts of existing (currently used) flow regulators is analyzed. The results of intensification of a real flow control regulator are presented.
