INLET VALVE WITH LATERAL WATER SUPPLY

The utility model relates to flushing devices with tanks, in particular, to inlet valves with side water inlet, and is intended to ensure the flow of water into the tank of the compact chamber in the specified volume.

Known inlet valve, comprising a housing, inside of which a filter is located at one end, and the other end is connected to a guide cover, in front of which a membrane is installed, and connected with a lever connected to a rod passing through the float in the center connected with the rod a cover-guide, while a water drain pipe is attached to the body (RU 138258, 03/10/2014).

The disadvantages of the known solutions include insufficient reliability in operation due to the complexity of the design, which does not provide a stable level of water in the tank and save water consumption.

The technical problem to which the proposed utility model is aimed is to expand the arsenal of technical means and create an inlet valve with side water inlet, the parameters of which support the fast water supply until it is completely closed and excludes the water supply when the water pressure in the network increases, and eliminate the above disadvantages and provide improved performance.

The technical result achieved by the implementation of this utility model is to simplify the design by eliminating the rods and the guide and, as a result, increasing the reliability in operation by ensuring a stable water level in the tank and saving water consumption.

The specified technical result in the inlet valve with lateral water inlet containing a float, a housing inside which there is a filter at one end and the other end connected to a cover connected with a lever, is achieved by the fact that the float contains a housing consisting of two open chambers: the upper and bottom, and mounted on the lever, and the cover is made with a spout for water drain, functionally connected with the open upper chamber of the float.

The float is installed with the possibility of shifting along a lever made of gear, which allows you to adjust the float placement according to the height of the tank and, as a result, more accurately adjust the level of water entering the tank, which further increases reliability in operation and saves water consumption.

The open upper chamber of the float is a water storage and is made with a groove in its side wall at the point of contact with the spout for water drainage. The groove serves for the outflow of water, which facilitates the float and increases the force of overlapping the calibrated hole in the cover, which additionally ensures reliability in operation of the intake valve.

A membrane is installed through the washer in the housing in front of the cover, which allows for quick water collection and instantaneous shutdown of the water (liquid) set and affects the reliability of the intake valve and saves water consumption.

The lever passes through the center of the float, held on it with an elastic element, which eliminates jamming and distortions of the float, simplifies the design of the intake valve and improves performance.

A water supply pipe is attached to the body, which serves to direct a jet of water to the bottom of the tank, thereby reducing valve noise characteristics, which also improves operational characteristics.

The cover has a calibrated hole, made with the possibility of overlapping through the liner of the lever when the float.

The membrane contains a membrane sleeve, on the core of which a groove is made, by means of which water enters the membrane cavity formed in the lid.

The implementation of the float from two open chambers: the upper (upper cavity) and lower (lower cavity), provides a stable level of water in the tank by changing the mass of the float during operation and eliminates the flow of water with increasing water pressure in the network over the entire range of its operating pressures, since the water entering through the nozzle of the lid into the upper chamber of the float, accumulating, increases the mass of the float and leads to its later ascent (water with its mass prevents premature float of the float, which supports the rapid flow into odes until the valve closes), and flowing out immediately after the float emerges, it creates a force capable of holding the valve in the closed position at maximum working pressure, while the valve design maintains simplicity in production and operation, increases reliability, and, as a result, improves operational characteristics of the intake valve, and the installation of the float directly on the lever greatly simplifies the design of the intake valve, eliminates jamming and distortions of the float, which ensures uniform filling The upper open chamber of the float and the stable water level in the tank also increase the reliability and performance of the intake valve.

Thus, in the claimed utility model, simplification of the inlet valve design, reduction of breakdowns and increased reliability in production and operation, saving water consumption are achieved.

The essence of the utility model is illustrated by the drawing, which shows a General view of the inlet valve with lateral water supply for the flush tank.

The inlet valve is installed through an opening in the side wall of the tank and secured with a nut 2. In this case, the gasket 3 should be located inside the tank. Using beveled washers 1, a horizontal arrangement of the intake valve body 9 is achieved when it is installed.

A water supply hose is attached to the housing 9 by means of a union nut. Inside the housing 9, a filter 6 is located at one end thereof. The other end of the housing 9 is connected to a cover 12 having a spout (tongue) for draining water 16.

A washer 10 and a membrane 8 are installed in front of the cover 12 in the housing 9. The cover 12 is connected to the lever 13. The cover 12 has a calibrated hole and is mounted on the housing 9 using a bayonet clamp, which also greatly simplifies the design of the intake valve. To the housing 9 is connected to the drain pipe 4.

The membrane 8 contains a membrane sleeve 7, on the core of which a groove (not shown) is made, through which water enters the membrane cavity formed in the cover 12.

"G" -shaped lever 13 is gear and is connected directly to the float 11, which also greatly simplifies the design of the intake valve.

The float 11 has an oval profile in cross section and two open chambers: the upper 14 and lower 15 (unclosed parts: lower and upper). The float 11 is made with the possibility of shifting the height of the tank on the lever 13. The open upper chamber 14 of the float 11 is a water storage and is made with a groove 17 in its side wall in contact with the spout for water drain 16. The float 11 is mounted on the lever 13, which made gear and passes through the center through the float 11.

Water enters the tank through an opening in the housing, squeezing the membrane. At the same time, through a groove made on the shaft of the membrane sleeve, water enters the membrane cavity formed in the lid. A calibrated hole is made in the lid, through which water in a small amount through the nozzle to drain the lid water enters the open upper chamber of the float, after which the water overflows also into the tank. As the tank is filled, the incoming water acts on the float, forcing it to rise and through the lever with a rubber insert to close the calibrated hole in the lid.

As a result, pressure increases in the membrane cavity and, due to the difference in area in the sub- and membrane cavities, the membrane closes the inlet in the valve body. The water supply to the tank stops. At the same time, water in the open upper chamber of the float flows out through a groove in its side wall, facilitating the float and increasing the force of overlapping of the calibrated hole in the cover.

After the water is drained from the tank, the float, falling together with the water level, through the lever with the liner, opens a calibrated hole in the lid, the pressure in the membrane cavity drops and the membrane opens the inlet in the housing, the cycle repeats.

Adjusting the water level in the tank is achieved by moving up or down the float, which is held on the lever with the help of an elastic element.
