flow control valve, polymer control organ, regulation accuracy, speed, workability of the construction


The existing hydraulic devices, with design based on the usage of “spool-and-sleevecylinder”, have disadvantages such as low speed reaction and reliability, due to high sensitivity to the pollution in working fluid and non-workability of the construction. The aim of the research is to substantiate, on the base of mathematical modeling and experimental studies the application in the construction of fluid control valve the control organ, made of the polymer material in the form of the envelope. The influence of geometric shell parameters on the quality of the control process is investigated. The conditions and directions of the most effective use of the regulator are established. The results obtained are engineering basis for the creation of the efficient construction of fluid control valve with polymer control organ of the envelope form with the enhanced technical characteristics.
