diffuser assembly for diffusing a liquid into irrigation installations, and irrigation installation comprising a plurality of diffuser assemblies

摘要

a diffuser assembly (1) for diffusing a liquid in irrigation installations (2) having a supply line (3) comprising a diffuser (10) with a nozzle (12) adapted to direct a jet of liquid along a longitudinal axis (l), at least one deflector (13) facing the nozzle (12) for radial outward spraying of the jet, and a connecting device (18) to ensure the fluid connection of the diffuser (10) to a supply (3) of the installation (2). the diffuser (3) is mounted in the irrigation system (2) with the shaft (1) extending in a substantially vertical direction and with the nozzle (12) facing upwards, and the deflector (13) is susceptible to pivot in around the longitudinal axis (l) thus causing oscillations in the assembly (1). the connecting device (18) comprises a tubular body (27) with end joints (28, 29) for connection to the diffuser (10) and the supply duct (3) and the body (27) is monolithic with the joints ( 28, 29) and is made of a thermoplastic elastomeric base material. furthermore, the body (27) comprises an outer surface (38) with annular folds (39), which impart elasticity and dampen the oscillations induced by the deflector (13). a pivoting or linear irrigation installation (2) comprising a plurality of said diffuser assemblies (1).
