Abstract

This bachelor thesis focuses on the selection of a suitable check valve to optimize the operation of a pump and reduce pressure losses within a piping system. The thesis includes a theoretical analysis of the functions, designs, and operational principles of various types of check valves and non-return flaps. Attention is also paid to the issue of local pressure losses and the influence of operational parameters on valve behavior. In the practical part, experimental measurements of two specific check valves – a non-slam check valve and a swing check valve – were conducted on a test rig under laboratory conditions. The measured data were evaluated with an emphasis on pressure losses under different flow conditions, supporting the proposal of an optimal solution for the defined pump system.
