New utility model registration Dosing device for liquid substances

The subject of the utility model is a device for evenly metering in liquid or dissolved solids Substances in a liquid flow = The device works according to the known injector principle and differentiates differs from conventional devices of this type by their simple design and the resulting small dimensions.

The device essentially consists of a piece of pipe with a thread for connection to the liquid line an adjustable dust cover with dosing spindle and a connection unit for the storage container of the liquid to be dosed, which can optionally be equipped with a backflow preventer *

The dosing device can easily be installed in any pipe system, with the total opening of the dust cover

is matched to the system pressure. The regulation of the amount to be dosed can be done with the dust cover as can also be used for fine adjustment with the dosing spindle. With correct adjustment of the dust cover and the dosing spindle, the desired amount of dosing liquid is sucked in from the reservoir by the flow of liquid and conveyed into the pipeline system «,

The storage container _3, which can consist of metal, plastic or glass, is expediently provided with a ventilation opening which, for example, can be closed with a stopper or provided with a cap that can be cut open. The container can be designed to be stationary or exchangeable and in the latter case also serve as a transport or sales container at the same time. The size of the container is expediently adapted to the effective consumption of dosing liquid in a specific time unit.

The connection of the container to the dosing device can be made with a hose connection, screw thread, bayonet lock or in the usual other way »The dosing liquid can be taken from the storage container ζ, B ₀ via a hose connection through a bottom opening« You can also use a container with a riser * by

which the dosing liquid is sucked in by means of a hose line hose nozzle of the dosing device.

The backflow preventer of the connection unit can consist of a lip valve, ball valve or some other backflow blocker exist. It is mainly used for short-term continu » more dosing and for systems with a long connection line between the storage tank and the connection unit With long-term continuous dosing or short ■ connecting line between feed tank and connection unit can be sealed on a backflow preventer.

In the attached drawing, two embodiments of the dosing device are shown for example »

Figure 1 shows the metering device, consisting of pipe section (l) _; Staublenöe (2), dosing spindle (3) with cap (8) » as well as the connection unit (4)" The connection unit is designed as a hose nozzle (5) and is provided with the non-return valve (7) designed as a lip valve. "The liquid to be dosed passes through the Opening (6) into the liquid flow.

Figure 2 shows the same device * but is the

The hose nozzle of the connection unit has been replaced by a screw connection (9) with an internal thread. This screw connection has a further internal thread (10) ₅ which is used to attach the riser pipe (12). The storage container (11), which is provided with a vent plug (13) _{or the like, is screwed into the device}

The device can be used wherever a certain concentration of liquid or dissolved solid Substances in other liquids are to be produced or maintained, e.g. when introducing liquids Additions in boiler feed water pipes., When introducing cleaning boosters in dry cleaning systems and especially when adding liquid detergents and cleaning agents, A particularly advantageous application is the use of the device for metering of facial cleaning and rinsing agents into the water used in dishwashers.

The device can be made of metal, plastic or glass. The connection of the device to the liquid line In addition to a screw connection, it can also be made by ground joint or fusing.
