摘要:
A multiple nozzle holder assembly with increased operating flexibility, comprising a main body provided with an inlet for a working fluid and with at least two outlets for the fluid, the inlet having a fluid connection to each outlet by means of a respective passage duct that is sectioned by corresponding valve elements for flow control with automatic actuation, an additional body being provided with at least three couplings for connection to respective atomizing nozzles, which is associated with the main body so that it can move among several operating configurations, at least two of which are delivery configurations in which selectively at least two of the at least three couplings each have a fluid connection to one of the at least two outlets.
摘要:
A mixer (1) for desedimentation of the precipitate in containment vats of at least one suspension for agricultural use, which comprises means for dispensing at least one pressurized fluid for washing the bottom (2) of a containment vat to lift and disperse the precipitate, the dispensing means comprising a first plurality (4) of nozzles (5) which generate concentrated jets (6) of the dispensed washing fluid which are mutually separate and at least directed toward the bottom (2). The mixer comprises means (3) for spacing the dispensing means from the bottom (2), which are adapted to be jointly associated inside the vat proximate to the bottom, the dispensing means comprising a box-like body (8) which is internally hollow and is provided with at least one inlet (9) for the washing fluid, which can be associated with means (10) for introducing the washing fluid under pressure, comprising a plurality of first seats (11) for accommodating at least the first plurality (4) of nozzles (5) arranged at least on the lower wall (12) of the box-like body (8) that is directed toward the bottom (2), the concentrated jets (6) of the nozzles (5) mutually diverging so that each one dispenses the washing fluid under pressure at least toward a specific region (7) of the bottom and so that the sediment is lifted from the region (7).
摘要:
A device for coupling supports for valves, nozzles, jets or the like to fluid distribution pipes, comprising a ring (6) that is divided into a first arc (7) and a second arc (8), which are mutually complementary and are pivoted (A) at a respective end (7a,8a), are free at the opposite end (7b,8b), and are suitable to surround externally a fluid distribution pipe (T), one of the first and second arcs (7,8) being associable with a support (4) for valves, nozzles, jets or the like, and a lever (10) for closing the ring (6), which is articulated to the opposite end (7b) of the first arc (7) and is provided with at least one tooth (11) for engaging a pin (12) formed at the opposite end (8b) of the second arc (8).
摘要:
A pneumatically-actuated membrane valve (1) for fluid branching ducts (2) comprises an internally hollow cylinder (11) associable with an end (2b) of the duct (2) that is substantially coaxial thereto and inside which a plunger (12) is slidingly accommodated, the head of the plunger (12) being adapted to interact with a circular membrane (13) for closing the end (2b) of the duct (2). The plunger (12) is actuated pneumatically between a closed or open configuration, and an open or closed configuration of the end (2b) of the branching duct (2), at least one abutment (19) for stopping the stroke of said plunger (12) being formed inside the cylinder (11).
摘要:
A universal head (1) for fixing a nozzle (9) to a fluid distribution duct (8) comprises a cap-like sleeve (10) adapted to be associated with the outlet of the duct (8), a nozzle insertion slot (11) formed at the top of the sleeve (10), and wings (12) for locking the nozzle (9) that can expand radially and are formed proximate to the slot (11).
