Study on Stability of Gas Pressure Regulator with a Built-In Silencer

Gas pressure regulators are widely used in gas transportation and distribution systems. They designed for deep reduction maintainance with high accuracy over a wide flow range. Operation at drop is accompanied by level of noise, which, silencers used. However, installation noise suppressor into the regulator design has significant impact on its static dynamic characteristics. This can lead to decrease accuracy, loss stability occurrence self-oscillations valve. These, turn, increasing vibration, wear contact surfaces premature failure regulator. The paper presents results study characteristics modernized serial built-in suppressor. A mathematical model was compiled carried out SimulationX software package. joint influence system parameters muffler block throttles, adjust characteristic regulator, considered. It shown that proper choice throttle resistances ensure control range rates. be when designing suppressors.
