Flow rate regulator in liquid conveying pipe - has shaped plug and spring loaded cylinder valve preventing turbulence

摘要

A capacity limiter used to regulate the flow of liquid in pipes so that no more than a predetermined quantity can flow. Control is achieved by means of a plug head, tension rod, cylinder valve, spring and a transmission element (5). The head of the plug (1) is flat on one side and the pressure can be calculated from the hydraulic equation. The other side of the plug is cone shaped in order to prevent turbulent flow. The forces are transmitted to the cylinder valve (3) via the tension rod (2). The bored cylindrical valve fits into the flow-through element. The closure of the flow-through opening starts when the force on the valve exceeds the tension in the spring. This will occur when a given rate of flow Q produces a force K on the plug-head via the tension rod.
