Abstract

SUMMARY OF THE INVENTION: The siphon is connected to a flush pipe whose diameter is equal to the diameter of the siphon fixed in the bottom of the chamber, the height of which is greater than the height of the siphon. The outlet of the exhaust pipe is placed with a gap above the bottom of the chamber. The bend radius of the siphon is equal to its diameter. The cross section of the chamber is equal to the width of the siphon in plan. The supply valve is made in the form of a safety valve that is closed after a predetermined period of time by the pressure of water in the water supply network and with a manual drive to open the valve. The supply valve is located above the chamber or in its upper part. The diameter of the inlet and outlet pipes is 1/3 of the diameter of the siphon, the gap between the outlet opening of the outlet pipe and the bottom of the chamber is the diameter of the outlet. 1 s.p. f-ly, 1 ill.

Description

The invention relates to sanitary equipment and can be used to flush toilets, floor chag and visuals installed in the sanitary facilities of buildings for various purposes.

The aim of the present invention is to expand the field of application of flush taps, reduce the flow rate of water supplied by the tap (3 times) while maintaining the required flow rate of water for flushing (1.5-1.8 l / s), reduce the diameters and material consumption of the feed system water supply.

To achieve this goal, in contrast to the known 1 flushing device, the bend radius of the siphon is equal to its diameter, the cross-section of the chamber is equal to the width of the siphon in plan, and the supply valve is made in the form of a safety valve that can be closed after a specified interval

time pressure of water in the water supply network and with a manually operated valve opening.

According to the calculated and experimental data, the useful capacity of the tubular container is 2-3 liters.

On top of the container is closed by a lid. A supply valve with a water flow rate of 0.5-0.6 l / s is placed above the tank or in its upper part, the inlet and outlet pipes of which have diameters that make up one third of the diameter of the siphon and flush pipe based on calculated and experimental data. In this case, the flow rate of the supply valve also makes up only one third of the flow rate of water flowing from the flush pipe (1.5-1.8 l / s). The outlet pipe is inserted into the container so that its outlet is located above the bottom of the container at a distance of its diameter, which ensures

quiet and silent filling of the tank due to the spreading of the jet along its bottom.

The drawing shows a flushing device in section.

The flushing device includes a supply pipe 1 through which water is supplied from the water supply system, a supply valve 2, made in the form of a safety valve, manually opened and automatically closed after a predetermined period of time by the pressure of water in the supply pipe, an outlet pipe 3 fixed in the lid or located at the top of the intermediate tubular tank A, a siphon flush pipe 5, tightly fixed in the bottom of the intermediate tank 4, a handle (or button) b. for manually opening the flush valve.

 The diameter of the exhaust pipe 3 is less than the diameter of the flush pipe 5. These diameters 8 are selected depending on the desired ratio of water flow from the exhaust pipe 3 and the flush pipe 5, which is 1: 3 according to the calculated and experimental data.

The principle of operation of the inventive device is as follows.

When you press the knob (or button) b, the supply valve 2 opens and water from the inlet pipe 1 through the outlet pipe 3 enters the intermediate tubular tank 4, quickly fills it and closes the siphon wash pipe 5, through which water with a flow rate necessary for smysha enters the toilet. At the same time, the water flow through the exhaust pipe 3 is 3 times less than the flow through the flush pipe 5, which makes it possible to use flushing devices in mass housing without increasing the diameters of the supply pipelines (racks, inlets). The operating time of the supply valve 2 is set such that after emptying the intermediate tank 4

automatically (by water pressure in the inlet) closes until the next manual start.

Use of the claimed flushing

devices in comparison with flushing tanks will ensure the complete elimination of water leaks and save drinking water, reducing the manufacture, installation and operation by simplifying the design and increasing

reliability in work.

The economic effect can approximately amount to 5 rubles per one flush valve. The manufacture of flushing devices of the proposed design is planned at the factories of the safety engineering industry. . .
