Definitions

  • the invention relates to a spray device for metering in a chemical concentrate with a pressurized water connection, nozzle spray head with a mixing chamber and an outlet valve to be opened by a trigger, as well as a rigid container placed in a metering outlet line and displaced with the aid of the water to be metered in via a concentrate outlet valve and a concentrate line into the mixing chamber of the nozzle spray head to be emptied, flexible chemical container.
  • Spray devices of conventional type for example injector sprayers or orifice metering devices, meter relatively imprecisely, that is to say that when the water flow rate changes and also when the water flow pressure changes, the percentage admixture of the metering chemical changes.
  • the devices also lack a shutdown in the event of a lack of chemicals or a drop in water pressure.
  • the overall solution according to the invention is characterized by the combination of the features of the characterizing part of the independent claim.
  • the minimum pressure valve unit preferably contains a valve piston which blocks the water inflow from the pressurized water connection below a predetermined water pressure by the force of an elastic spring.
  • the pressure of the water connection or the water system pressure generally does not need to be reduced within the sprayer.
  • the rigid container containing the chemical, in particular in a flexible bladder, preferably in a disposable design, can therefore be subjected to the water system pressure during operation.
  • dosing that is independent of pressure and flow is therefore proportional to the quantity and spraying achieved.
  • the pressurized water supply preferably contains a multi-way valve, in particular a 4/2-way valve, with a common outlet to the nozzle spray head and to the metering pump and with further - alternately acting - outlets on the two sides of the drive piston of the water motor.
  • a multi-way valve in particular a 4/2-way valve
  • the suction line of the metering pump i.e. H. the branch line leading to this pump is connected to the pressurized water supply before or after the multi-way valve.
  • a spray gun is shown in section as an exemplary embodiment.
  • These include a pressurized water connection 1 on the handle 2, a spray head connection 3 with mixing chamber 4 and actuating valve 5 with linkage 6 and trigger 7, as well as a metering pump, designated overall with 8, with a pump drive designed as overall with 9 designated water motor for metering proportionally one from a as Disposable bladder 10 formed chemical container coming chemical concentrate via a concentrate outlet valve 11 and a line 12 into the mixing chamber 4.
  • the water coming from the direction of the arrow 13 (with an interposed fine sieve 14) is opposed by a piston 15 by the force of the spring 16 so that the pressurized water can only flow into the device when a certain threshold or minimum pressure is exceeded.
  • the details of the minimum printing unit, denoted overall by 17, result directly from the drawing.
  • the feed water line 19 leads to a 4/2-way valve 20.
  • the valve 20 has a first outlet 21 with a branch line 23 containing a branch 18 and a check valve 22 to the mixing chamber 4 as well as two further outlets to be acted upon alternatively 24 and 25 to the two sides of the drive piston 26 in the cylinder 27 of the water motor 9.
  • the 4/2-way valve 20 can be switched over by a piston 28 by means of the piston 26 during the reciprocating movement of the piston.
  • a second branch line 29 leads via a check valve 30 to the double-acting metering pump 8.
  • the metering piston 31 of the metering pump 8 is firmly coupled to the piston 26 of the water motor. It should be noted that the area ratio of the piston 26 of the water motor to the piston 31 of the metering pump must be predetermined. The remaining details of the metering pump 8 result from the accompanying drawing.
  • a rigid container 33 (which has solid walls) is placed in a metering outlet line 32 of the metering pump 8 which contains a valve 38 and is displaced with the aid of the water to be metered in (displacement principle) via the concentrate outlet valve 11 and the line 12 with the mixing chamber 4 of the Spray head connector 3 coupled flexible chemical container provided as a disposable bladder 10.
  • the valve 38 placed in the metering outlet line 32 is closed when the container 33 is removed and is opened by plugging the container on.
  • Another feature of the invention explained with the aid of the spray gun is that of the pressure water supply line from the metering cylinder 34 to a rigid container 33 to be pressurized in the metering pump 8 or in the case of a rigid container 33 to be pressurized with water by the pump or when the valve 38 is blocked 36 leading feedback line 37.
