TH7466B - Spray nozzle for faucets used with sinks, crockery or the like. - Google Patents

Abstract

Spray nozzle (1) for faucets used on sinks (2) or similar devices. which this spray nozzle Suitable for connection to low pressure storage tanks. (Open hot water tanks) with a water outlet (4) Normal spray emitter (7), especially located in the central part. The spray emitter (9) is located especially around the normal spray emitter (7) concentrically. And there are many small spray holes (10) and adjustable tongue (13) which when in the normal position. The adjusting valve (13) will connect the emitter. the normal spray current (7) and the outlet (4) and separate the spray emitter (9) from the outlet (4) and when in spray position The adjustment valve connects the spray emitter (9) to the water outlet (4) and separates the normal spray emitter (7) from the water outlet (4), suitable for use in connection with the tank. Very low pressure is kept by the drain hose (21) operating in the spray position. provided in the adjustment valve (13) between the water supply path (4) and the normal spray emitter (7), and the discharge pipe flow resistance (21) is greater than the resistance of the spray emitter ( 9) When no spray hole (10) is added, but the maximum working kinetic pressure generated at the source from the drain (21) when spray hole (10) is added is less. Nominal low pressure storage tank explosion pressure

Claims (4)

Disclaimers (all) that will not appear on the advertisement page: 1. Spray nozzle (1) for faucet used with crockery sink (2) for connection to low pressure tank. The spray nozzle consists of a water supply unit (4), a conventional discharge unit (7), a spraying discharge section (9), which surrounds a common concentric discharge (7). It has many small spray holes (10) and reversible valves (13) where in its normal position, the reversible valve (13) connects the normal discharge section (7) to the water supply. (4) and separate the spray discharge section (9) from the water supply section (4) and in the spray position, the spraying discharge section (9) is connected to the water supply (4) and blocks the flow of water. To the normal discharge section (7) from the water supply section (4) where the drain hose (21) acting in the spray position is placed in a reversible valve. So that there is a flow path between the water supply section (4) and the normal discharge section (7) and where the drain flow resistance (21) is greater than the flow resistance. Of the spray discharge section (9), when the spray hole (10) is not clogged to make the flow Special to the spray discharge section But it is low enough to let the flow through the vent hose during the spray nozzle operation. When there is a blockage of the spray hole to the limit Dun kin max Occurring at the pressure from the drain pipe (21) to the tongue where there is less pressure than pressure Related low pressure storage tanks explosion 2. The spray nozzle (1) according to claim 1, where the drain hose (21) is placed in the tongue body (16) of the reversible tongue (13). 3. Spray nozzle (1) according to claim 2, where the tongue body (16) is a shoulder-type tongue. Supports that can be moved in an axial direction And where the drain pipe (21) is made as a central axial channel in the tongue (16) 4. The spray nozzle (1) according to claim 3, where the valve body (16) is positioned on the connecting rod (19) with a slit along the central axis, and with the connecting rod (19) facing forward. The end facing the normal discharge section (7) and the side facing the normal discharge section. The spray flow (9) has a side inlet (22) to the channel formed by a drain (21).
