Document Type and Number:
WIPO Patent Application WO/2023/060648
Kind Code:
A1
Abstract:
The present invention relates to the field of municipal water supply. Disclosed is a performance testing device for a water supply pipe network pressure management system based on a pressure reduction valve. The device comprises a pool (1), wherein the pool (1) is in communication with a main water intake pipe (7) by means of two pipes, and the main water intake pipe (7) is in communication with a pipe network (13); the two pipes are each provided with a manual valve (3), a pool booster pump (2), a check valve (5) and an electric valve (6), which are arranged in sequence, and a flexible joint (4) is provided on both the front and the back of the pool booster pump (2); the main water intake pipe (7) is provided with a pressure reduction valve (8) and a first electromagnetic flow meter (91); and a water return pipe (12) is led out from the pipe network to be connected to the pool (1), and the water return pipe (12) is provided with the electric valve (6) and a second electromagnetic flow meter (92). In this way, the pressure regulation accuracy, sensitivity and stability of a pressure management system based on a pressure reduction valve can be tested, and the effect of controlling a system leak is verified.
