Description

The utility model relates to medical equipment and can be used to increase the efficiency of water treatment for washing and disinfecting plants, intended primarily for the processing of flexible endoscopes and other channel medical instruments.

The prior art water treatment device for washing and disinfecting installations, including an inlet pipe connected to a cold water main, to which a coarse filter, a gearbox, a fine filter, a pump equipped with a flow sensor, and an outlet pipe (RU 173452 Ul , A61L2 / 02, 2017). The main disadvantage of this technical solution in the presence of constructive complexity is the lack of means to ensure the supply of prepared water to consumers with a decrease in pressure in the cold water main, which reduces the reliability of the water treatment device.

The technical result, to which the utility model is directed, is to increase the reliability of the water treatment device by providing consumers with prepared water while reducing the pressure in the cold water supply.

The solution of this problem and the achievement of the claimed technical result is ensured by the fact that in the water treatment device for washing and disinfecting installations, containing an inlet pipe connected to a cold water supply line, to which a coarse filter, a gearbox, a fine filter, a pump equipped with a sensor are connected in series flow, and the outlet pipe, according to a utility model, between the pump and the outlet pipe included a hydraulic accumulator with elastic diaphragm, and the gearbox at the outlet is equipped with a check valve.

In addition, shutoff valves are installed at the inlet and outlet pipelines.

The presence of a hydraulic accumulator with an internal elastic membrane that separates the internal volume into air and water chambers, the last of which is connected to the water circulation system, ensures that the pressure in the water treatment system is stable and, when the pressure in the cold water supply line is reduced, it supplies the prepared water to consumers, which increases reliability the operation of the water treatment device.

The drawing shows a diagram of the circulation system of the claimed water treatment device for washing and disinfecting installations.

The device of the water treatment circulation system includes an inlet pipe 1 connected to a cold water supply line, equipped with shutoff valves - a valve 2, and a coarse filter 3, a gearbox 4, equipped with a check valve 5, a fine filter 6, a pump 7, equipped with a sensor 8 flow, a hydraulic accumulator 9 with an internal elastic membrane 10 dividing the internal volume into a water chamber 11 connected to the circulation system, and an air chamber 12, and an outlet pipe wire 13 with stop valve - cock 14. Water circulation system provided with a pressure gauge 15 monitors the pressure at the inlet and outlet water treatment device.

The claimed water treatment device for washing and disinfecting installations works as follows.

When the valve 2 is opened on the inlet pipe 1 and the closed valve 14 on the output pipe 13, cold water enters the circulation system from the cold water supply line, which sequentially passes through the filter 3 for rough cleaning, where the mechanical impurities are cleaned, the gearbox 4, equipped with a check valve 5 , which stabilizes and reduces the pressure of the water coming from the cold water supply to the required pressure in the circulation system, a fine filter 6, where bacteriological impurities up to 0.1 ÷ 0.2 microns in size, and enters the hydraulic accumulator 9, filling the water chamber 11, and compressing the previously pumped air in the air chamber 12. Then open the valve 14 on the outlet pipe 13 and the prepared water from the circulation system of the device enters the washing and disinfecting installation.

When the pressure in the cold water supply line decreases, a pump 7 is turned on, which maintains the pressure of the prepared water in the circulation system of the device at the required level. After filling the washer-disinfecting installation with prepared water, close the valve 14 at the outlet pipe 13, while the flow rate of the prepared water reaches zero and the flow sensor 8 turns off the pump 7.

With a significant decrease in pressure or lack of water in the cold water supply, the prepared water enters the washing and disinfecting installation from the water chamber 11 of the hydraulic accumulator 9 under the action of compressed air pressure in the air chamber 12.
