Description

The field of technology.

The claimed technical solution relates to the field of water installations for fresh water used inside buildings, and is intended for use in residential premises and houses, as well as in public restrooms (including cafes, restaurants, shopping centers, gas stations, train stations and airports ), where taps are used to organize the flow of fresh water (sinks, wash basins, sinks, showers).

The prior art.

The prior art device for saving water (patent for utility model RU 125214, IPC E03C 1/04, 2013), comprising a water inlet and a water outlet, between which a channel is organized. A locking unit is installed in the channel, which is a ball with a through hole, mounted in the channel with the possibility of rotation. In the fully open position, the ball hole is placed along the channel and water can pass through it. In the fully closed position, the hole of the ball is oriented across the channel and the channel is completely blocked. In the intermediate position, a partial overlap of the channel and the hole of the ball is provided.

The specified analogue provides full or partial closure of the channel, which allows you to use it as a device to save water. To supply water with a reduced flow rate, the channel of the device for saving water should be partially closed.

The disadvantage of this analogue is the presence of a rotary locking ball. This complicates the design, increases the material consumption of the product and the complexity of its manufacture. In addition, the use of a rotary ball with a long partial opening leads to the formation of deposits on the outer surface of the ball in the place where it partially protrudes into the channel. It is known that this leads to the fact that the crane ceases to completely shut off when the complete overlap of the channel is required.

Also known is a water-saving element made of synthetic resin (Japanese patent document JP-A-2000-96645 (P2000-96645A), IPC E03C 1/086, 2000) containing a water inlet and outlet, between which a narrowing channel is organized, in the narrowest section having circular cross section, the diameter of which is from 2 to 6 mm. A water-saving device is a faucet with an outlet for draining tap water, to which a water-saving element is fixed. The water-saving element is fastened by clamping it between the edge of the outlet and the holder having threads for this. The thickness of the water-saving element is from 5 to 10 mm.

The disadvantage of this analogue is the design complexity of a water-saving device, consisting of several structural parts that must be interconnected. In addition, the complexity of the shape of the water-saving element leads to the need for finishing processing of the element on both sides.

A water-saving device, known from a patent publication in Japan, is the closest analogue of the claimed technical solution.

Disclosure of the claimed technical solution.

The technical problem, to the solution of which the claimed technical solution is directed, is to ensure water savings with minimal user control.

The technical result provided by the claimed technical solution is to simplify the design, reduce the material consumption of the device and the complexity of its manufacture.

The essence of the claimed technical solution lies in the fact that the device for saving water contains an inlet and outlet of water, between which a narrowing channel is organized. It differs in that the channel is conical and in the narrowest section has a circular cross section, the diameter of which is from 2 to 10 mm.

The above essence is a combination of essential features of the claimed technical solution, ensuring the achievement of the claimed technical result.

In special cases, it is permissible to carry out the technical solution as follows.

In the narrowest section, the channel preferably has a circular cross section, the diameter of which is from 2.7 to 3.3 mm. This design is appropriate for most apartments. In other applications, this diameter can be from 2 to 3 mm (for an individual water saving device for each tap) or from 3.8 to 4.7 mm (for apartments with two shower rooms).

The author of the claimed technical solution made a prototype of this solution, the tests of which confirmed the achievement of the technical result. Saving water when using the device ranged from 40 to 50%. At the same time, sufficient water flow is provided for the washbasin, sink and shower.

A brief description of the drawings.

The figure shows a longitudinal section of a device for saving water.

Implementation of a technical solution.

A device for saving water has an inlet (1) and an outlet (2) of water, between which a channel (3) is organized. The water inlet and outlet are preferably configured to be connected to a household water supply engineering network.

The channel is made with a variable cross section. In the narrowest section, the channel has a circular cross section, the diameter of which is from 2 to 10 mm. For apartments and houses with two bathrooms or shower rooms and one kitchen sink, it is preferable to make a channel in the narrowest section with a diameter of 3.8 to 4.7 mm. For apartments and houses with one bath or shower room and one or two kitchen sinks, it is preferable to make a channel in the narrowest section with a diameter of 2.7 to 3.3 mm. When installing a device for saving water individually on one tap, it is preferable to run the channel in the narrowest section with a diameter of 2 to 3 mm.

The channel is made conical. In this case, a smooth narrowing of the water flow in the channel and a slight decrease in hydraulic resistance are ensured.

Examples of specific performance.

Example 1. The water saving device is made of metal, for example, of brass. The water inlet and outlet are made with a circular cross section with an internal diameter of 1/2 inch and are provided with a thread on the outer surface. The diameter of the internal section of the inlet and / or outlet may be 3/4 inch or 1 inch. The inlet and / or outlet may be provided with a union nut instead of a thread.

Example 2. The water saving device is made of painted metal. The water inlet and outlet are made with a circular cross section with an internal diameter of 1/2 inch and are provided with a thread on the outer surface.

Example 3. The water saving device is made of plastic or metal plastic. The water inlet and outlet are made with a round cross-section with an inner diameter of 1/2, 3/4 or 1 inch.

The implementation of the proposed technical solution is not limited to the above examples. In particular, the device can be made of any steel, stainless steel, aluminum or aluminum alloy, bronze, copper.

Description of work.

A device for saving water is preferably installed at the water inlet into the room (apartment, house) after the water meter and the filtration system. When used individually for a crane, the device is installed directly in front of the crane.

When the tap is opened, the device for saving water limits the flow of water due to the narrowing in the channel (3). At the same time, the diameter of the narrowest place in the channel ensures comfortable use of water (for washing and washing hands, for taking a shower, for washing dishes), while saving water.

Industrial applicability.

The claimed technical solution is implemented using industrially produced materials, can be manufactured at any industrial enterprise, and will find wide application in the field of plumbing installations.
