SU147546A1 - Flush tank - Google Patents

Description

Known flush tanks with bellows valve with attached} th to the upper open end of its float. However, such tanks do not ensure reliable closure of the drain hole, as a result of which continuous water leaks occur.

The described invention relates to the same type of flush cisterns and is intended to protect against water leaks. This is achieved by the fact that the drain hole of the gate in the initial position is located above the water level in the tank. In addition, in this tank, in order to ensure the constancy of the flow rate, the water during flushing due to the constant distance between the level of the drain hole, a floating P1 siphon was used.

FIG. 1 shows a flush tank; in fig. 2 - the same, with a floating siphon.

In the ceramic case /, closed by a cover 2, there is a bellows valve 3, the lower end of which is fixedly attached to the drain pipe 4, and a plastic float 5 is attached to the upper open end, which is the drain hole.

Thus, the drain hole in the initial position is located above the water level in the tank.

Water is drained from the tank by pressing the handle of the rod 6, which passes in the guide sleeve of the lid and is fixed in the center of the float. At the same time, the float is lowered below the water level, compressed sylphop, causing the water to rush into the drain hole.

Simultaneously interacting with the float lever 8 presses the ball valve 9 and opens the access of water to the tank, which, filling this, raises the float 5 to its original position. In this position, the lever releases the valve 9, which pops up and is pressed by pressure from the water line to the rubber nozzle 10.

In the event of a malfunction of the valve, the water will not exceed the permissible level, as it will be drained through the open drain port of the bellows.

In the embodiment illustrated in FIG. 2, the float V / has a siphon cavity 12 for automatically draining water by siphoping. This effect is formed with a slight initial immersion of the float as a result of external influence. Such a float with a combined siphon ensures the constancy of the water flow during the flush by maintaining a constant distance between the water level and the drain hole.
