Abstract

In this paper, issues that need to be considered when designing direct-flow gas pressure regulators of direct action are addressed. A constructive scheme of a piston type gas pressure regulator is presented. Experimental studies of gas pressure regulators of standard sizes DN50 and DN80 at the facility of the existing gas pipeline were conducted, and adjustment of regulators was carried out at the pneumatic stand of the university. The influence of friction forces on the quasi-harmonic low-frequency self-oscillations of the control system is shown. This phenomenon is due to the nature of friction when using rubber and fluoroplastic sealing rings in the moving elements of the regulator and the presence (or absence) of a film of lubricant. This is directly related to transients, stability conditions in transients during regulation due to changes in gas flow.
