Flush tank

FIELD: construction.

SUBSTANCE: tank comprises a vessel with devices of its filling and drain. The body is arranged in the form of a toroidal chamber 1 with a rigidly mounted partition 10 and a piston 9 installed in it with the possibility of reciprocal motion, which in extreme positions interacts by one of two opposite mutually spring-loaded valves 24 of counterpressure to its displacement, with a slide valve 17 of a hydraulic distributor, installed in the partition and connecting two cavities formed by walls of the partition and the piston, alternately - with inlet and outlet holes.

EFFECT: reduced volume of water due the possibility to control its flow and using its flow during wastes direction into a toilet sink, but not afterwards.

 

The invention relates to sanitary engineering and can be used for flushing toilets.

Known flush tank, comprising a housing located in it devices filling and discharge (patent No. 2183707 of the Russian Federation, published 20.06.02,).

Providing a flushing toilets, drain the device of this tank does not differentiate between the amount of water used depending on the degree of contamination and the nature of impurities.

As the prototype is set flush tank, comprising a housing located in it devices filling and discharge, is supplied along with the primary and secondary node discharge a measured amount of water (patent No. 2162498 of the Russian Federation, published 27.01.01,).

The disadvantages include the inability to change the volume of water when dosed discharge directly by the user during operation of the tank - depending on the specific need, and also the lack of ability to control the duration of the rinse cycle. In addition, similar to the flush tank, due to the constant presence of water in the body and, therefore, deposition on the walls of sediment from micro inclusions rust and other items that require periodic maintenance cleaning.

An object of the invention is to increase the efficiency of water use, as well as eliminating the need for periodic is practical sanitation housing and located in a device.

The problem is solved due to the fact that in the flush tank, comprising a housing located in it devices filling and draining the water, the body is made in the form of a toroidal chamber with hard and bassethorn mounted partition and set it to swinging movement of the piston in the extreme positions of interacting, one of two oppositely located there vzaimopodchinennym valves backpressure his move, with the control valve spool installed in the wall and connecting the two cavities formed by the partition walls and the piston, alternately with the inlet and outlet ports. The invention is illustrated by drawings, where

- figure 1 shows a General view of the flush-water tank, front view;

- figure 2 is a side view, in direction of the arrow a in figure 1;

- figure 3 is a section along the plane of the connector toroidal chamber of the tank in one of the end positions of the piston B-B in figure 2;

- figure 4 is a section along the plane of the connector toroidal chamber of the receptacle in the other extreme position of the piston in the initial moment of contact with the control valve spool B-B in figure 2;

- figure 5 is a transverse section of the walls, as In figure 3.

Flush the tank consists of a toroidal chamber 1 (Fig 1), mounted on the plate 2 through the cradle 3, the bracket 4 and the clamping screws 5. SC is BA made with 4 screw holes for mounting of the valve 6 and pipe 7 water supply, as well as the cavity 8. In the toroidal chamber 1 is located the piston 9 and the partition wall 10 is installed therein a valve 11, a valve 12 which is made with shanks 13 and 14 and with the belts 15 and 16. The partition 10 has a system of holes 17 and 18 for supplying water in the cavity 19 and 20 of the toroidal chamber 1 and the holes 21 and 22 of the water drain through the hole 23 in the plate 2. The piston is made with two vzaimopodchinennym and oppositely arranged therein a valve 24 back pressure that occurs when it is moved.

Flush the tank works as follows.

The valve 6 is translated in open position. Due to the location of the spool 12 in one of two fixed positions, the water from the pipe 7 through the cavity 8 in the bracket 3 and, as shown in figure 3, through holes 17 is supplied into the cavity 19 of the toroidal chamber 1. When the piston 9 begins to move and, due to the open system of the holes 22, to displace located in the cavity 20 of the air (when you first use the flush-water tank). Pressure effects on the piston is equal to the pressure of the reaction, which occurs when it is moving, i.e. the magnitude of the back pressure. Valve 24 closed. When the piston 9 to the shank 14 of the spool 12 and the touch of his valve 24, when moving, the latter begins to move inside of the piston 9. Due to the fact that the axial detent gold the ICA 12 exceeds the force of the compressed valve 24 springs tapping the piston 9 partition 10 in the cavity 19, the pressure increases until the pressure in the water supply. The second valve 24 begins to move inward of the piston 9, compressing the spring further and, when reaching the force of its compression magnitude greater than the axial detent spool 12, the last, the first valve 24, is translated into a second position in which the open system of water supply ports 14 and 21 plum and locked previously opened 17 and 22. Starts the return movement of the piston 9 and, respectively, to drain water from the cavity 19, and with a flow rate set by the degree of opening of the valve 6. When the piston 9 to the shank 13 of the valve 12 and moving the latter is translated in the above order in the original position. The drain cycle water is repeated. After cleaning the toilet valve 6 is switched off. The water remaining in the cavities 19 and 20, due to the tightness of the toroidal chamber 1, is not merged. The flow of water into the toilet pulsating flow significantly accelerates the removal from its surface adhered waste, as the initial contact with them moving the front surface water flow is repeated several times. And as you know, with a sudden collision of the flow of water with the last obstacle feels the effect of significantly increasing the pressure (in comparison with the ambient flow), so called aemula hydrodynamic shock. In addition, systematic reciprocating rotational movement of the piston 9 prevents the walls of sediment.

Thus, the execution of the flush-water tank housing in the form of a toroidal chamber with hard and bassethorn mounted partition and set it to swinging movement of the piston in the extreme positions of interacting, one of two oppositely located there vzaimopodchinennym valves backpressure his move, with the control valve spool installed in the wall and connecting the two cavities formed by the partition walls and the piston, alternately with the inlet and outlet ports, can significantly reduce the amount of water due to the possibility of regulation of its flow and use of water flow in the time direction (regardless of duration) waste the toilet and not after. In addition, the pulsating flow of water can increase the number of strikes the front surface of the water about the stuck waste, which greatly reduces the time required to remove them. It also prevents precipitation of impurities contained in the water.

Flush tank, comprising a housing with a device of its filling and discharge, characterized in that the casing is made in the form of a toroidal chamber is rigidly mounted what regardly and set it to swinging movement of the piston, in the extreme positions of interacting, one of two oppositely located there vzaimopodchinennym valves backpressure his move, with the control valve spool installed in the wall and connecting the two cavities formed by the partition walls and the piston, alternately with the inlet and outlet ports.
