Gas supply system`s pressure regulator, has spring designed such that spring has minimum pressure, where spring subjected to blower air provides additional force for pressure boosting from minimum pressure by regulator

摘要

The regulator has a compression spring (3) designed in a manner such that the spring has a minimum pressure, where the spring is contributed as basic force over entire control range, and the minimum pressure is held by the regulator in a blower independent manner. The spring subjected to blower air provides additional force for pressure boosting from minimum pressure by the regulator, where the spring pressure on a diaphragm (2) is adjusted by hand or a motor, so the downstream of spring is regulatable.
