Abstract

FIELD: sanitary engineering equipment, applicable for flushing of water-closet pans, low-ground bowls, bidets installed in toilets of buildings of various purpose. SUBSTANCE: the flush device comprises a water conduit, feed pipe with an angle valve and a flush cock; a tee branch pipe with a mounted-in nozzle connected to the water conduit is made between the water conduit and feed pipe; the feed pipe of the flush cock is connected to the tee branch pipe opposite the nozzle and coaxially with it, connected to the tee branch pipe on one side by means of an elbow is a vertical supply tank with a tankage of 2-2.65 times lower than that of the known flush tanks; the diameter of the water conduit is smaller than the diameter of the flush tank feed pipe by 2-2.65 times. EFFECT: use of flush cocks instead of flush tanks. 1 cl, 1 dwg

Description

 The invention relates to sanitary equipment and can be used to flush toilets, floor bowls and viduars installed in sanitary units of buildings for various purposes.

 Flushing taps (1) are known for flushing toilets. However, they can work effectively only in specially designed water supply systems with increased diameters of risers and eyeliners, which does not allow them to be used instead of closure tanks in systems with smaller diameters of risers and eyeliners.

 The technical result of the invention is the provision of the possibility of using flushing taps instead of flushing cisterns for washing toilet bowls, floor bowls and viduars.

 To achieve this goal in the claimed invention between the water supply leading from the riser, and the flush valve mounted on the toilet, a device is made including a nozzle, tee, elbow and a pressurized pressure tank with a capacity of 2 - 2.5 times less than the useful capacity of a known pressureless flush tank .

 The drawing shows a diagram of the flushing device assembly and its nodes in section.

 The device comprises: a water supply pipe 1, a sleeve 2, a lock nut 3, a nozzle 4, a tee 5, a supply pipe 6 with an angle valve 7, a flush valve 8 with a trigger handle 11, a flush pipe 9, a toilet bowl 10.

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

 When pressing the handle 11 for 1 - 2 s, the flushing valve 8 opens and water from the water supply pipe goes through the inlet 1, nozzle 4 to the tee 5, creates a vacuum in it and sucks the water through the elbow 12 from the tank 13.

 Mixed water from the inlet 1 and the tank 13 with a flow rate of 2 -2.5 times greater than the flow rate of the water from the inlet 1 ,; enters through the inlet pipe to the flush valve 8, the flush pipe 9 and to the toilet 10. After 3 to 7 seconds after starting, the flush valve automatically closes (this is the principle of the flush valve) and the entire device, including the pressure tank 13, is quickly filled with tap water and, being under its pressure, ready to restart.

Claims (1)

 A flushing device for washing toilet bowls, floor bowls and fidgets, including a water supply pipe, a supply pipe with an angle valve and a flush valve, characterized in that a tee is made between the water supply pipe and the supply pipe of the flush valve connected to it with a water supply pipe, supplying the flush pipe is connected to the tee opposite the nozzle and coaxially with it; on the side of the tee, a vertical pressure tank with a capacity of 2 - 2.5 times less than the capacity is connected using a square known cisterns, the diameter of the tap fittings 2 - 2.5 times less than the supply pipe to the cistern.
