摘要:
An aeration nozzle (11) for spraying water infused with air into an above-ground water cavity (13) defined by a wall (4) comprises a nozzle body (17) having at least a first internal conical portion including an upstream end and a downstream end, the downstream end being smaller than the upstream end; a water way (15) extending through the nozzle body (17) and the first internal conical portion; an air way (14) extending through the nozzle body (17), the air way (14) intercepting the water way (15) within the nozzle body (17) downstream of the first internal conical portion, and a check valve (22) disposed along the air way (14) that permits air to be pulled through the air way (14) and into the water way (15) by way of a vacuum force caused by water flowing within the water way (15) through the first internal conical portion and prevents water from entering the air way (14).
摘要:
An inflatable spa (100) is disclosed comprising a water cavity (112). The inflatable spa (100) further comprises a control system (200) having an air pump (232), a first check valve (260), positioned in an air passageway (230), and a drain valve (280). The first check valve (280) closes when the air pump (232) is stopped to prevent a backflow of water from the water cavity (112) to the air pump and opens under pressure from the air pump. The drain valve (200) opens when the air pump (232) is stopped to drain any water from the air passageway (230) and closes under air pressure from the air pump.
摘要:
It is described a fluid jet generating and conveying circuit (1) for a whirlpool tank (2), provided with a blower (3), distribution means (4) supplied by said blower (3) by means of a conveying conduit (5) and connected to one or more outlets (6) of said bath (2), primary safety means (8) comprising a check valve (15) arranged along said conduit (5) to prevent backflows of water from the bath (2) from reaching said blower (3), and secondary safety means (10) having the same function as the primary safety means (8) and acting in the event of malfunctioning of the latter; the secondary safety means (10) comprise a chamber (25) having an outward opening (26) connected to said conduit (5) in a position so as to entirely receive possible flows of water from the primary safety means (8), and a float (27) housed in the chamber (25) in a closed position of said opening (26) and shiftable, by effect of the presence of water, to an ajar position of said opening (26) to allow the evacuation of the water itself.
摘要:
An air bath (10) has air outlets (22) extending around the side walls (16) of the water basin (12). Air is delivered to the air outlets through a ring-like air manifold (24) coupled to a blower (26) by conduit (30). The conduit has a bypass vent (80) that siphons off a portion of the air flow otherwise passing to the air outlets and maintains the blower in communication with ambient air. The air delivery system provides a wider range of bubble densities by allowing the blower to operate at lower speeds without overheating or stalling from back pressure arising from the pressure head of the water in the basin.
摘要:
An apparatus (10A) for removing standing water from the hydraulic plumbing system that circulates water in a whirlpool bath. The apparatus includes a pneumatic pump (50A) fluidly coupled to the whirlpool hydraulic plumbing system of a whirlpool bathtub (20A), such that air pressure from the pneumatic pump can be used to flush standing water out of the hydraulic plumbing system after each use. A pneumatic plumbing system connecting the pneumatic pump to the hydraulic plumbing system is positioned substantially above maximum water level allowed in the tub and also substantially above the hydraulic plumbing system.
摘要:
Die Erfindung bezieht sich auf eine Wanne (1) mit einer eine Luftaustrittsdüse bildenden Luftzuführungseinrichtung zum Erzeugen eines Luftsprudels in dem Wannenwasser, mit einem Ventil (2) zur Vermeidung des Rückflusses von Wannenwasser in die Luftzuführungsleitung (3), wobei das Ventil (2) einen mit einem Ventilsitz zusammenwirkenden Verschlußkörper (4) aufweist, welcher mittels eines Druckfluids gegen die Wirkung einer Rückstellkraft, z.B. die Wirkung einer Rückstellfeder (5), aus einer Schließstellung in eine Öffnungsstellung bewegbar ist, in welcher Druckluft in den Wanneninnenraum (6) austreten kann. Zur Gewährleistung einer sicheren Schließfunktion und zur Vermeidung eines Eintretens von Wannenwasser in das Ventilgehäuse (10) und die Luftzuführungsleitung (3) ist vorgesehen, daß die Rückstellkraft auf den Verschlußkörper (4) in einer Richtung einwirkt, welche der Strömungsrichtung der dem Wanneninnenraum (6) unter Erzeugung des Luftsprudels zuzuführenden Druckluft im Bereich des Ventilsitzes (19) gleichgerichtet ist und daß das Druckfluid zur Erzeugung des Luftsprudels über eine Betätigungseinrichtung (7) auf den Verschlußkörper (4) in einer Richtung einwirkt, welche der Strömungsrichtung der dem Wanneninnenraum (6) zur Erzeugung des Luftsprudels zuzuführenden Druckluft im Bereich des Ventilsitzes (19) entgegengerichtet ist.

摘要:
In a hydromassage fitting (10) a first sleeve (54), a jet generator mounted on an orientable spherical body (12) and containing an axially movable nozzle (60),actuated by an external actuator (82), said nozzle being retracted under the control of said external actuator (82) to leave a passage space for the jet water, said nozzle (60) comprining a non return valve (100) adapted to permit the flow of fluids from inside to outside of the nozzle but not viceversa, thus acting as a check valve to prevent the backflow of water from a tub served by said fitting (10) to the air pipings of said fitting, said nozzle (60) cooperating with the sleeve (54) to prevent, in the extended position, the backflow of water from said tub to water circulation circuits of said fitting.
