Study on the characteristics of a new type pneumatic pressure regulator

ressure regulators are very important elements in pneumatic systems. Purely mechanical pressure regulators are commonly used to control the supply pressure to the desired value. The intelligent pneumatic pressure regulator (IPPR) is designed as the demands of pressure control precision increase. Its prominent advantage is the ability to achieve accurate output pressure, remote control and centralized management. In this paper, the IPPR consists of a mechanical valve body, a stepping motor, a microcontroller, a pressure sensor. Herein, its pneumatic characteristics were analyzed, and the pressure control algorithm was presented. The superior performance of IPPR was shown in AMEsim simulation, especially in terms of avoiding affects from upstream pressure and downstream flow disturbances.
