The shut-off device for c alIdust tank consists of a cylindrical body 1, made in the form of a glass, on which a cover 2 is put on top, having a hole in which the valve 3 moves, made in the form of a hollow rod. At the bottom (L N9 CO with ND 00 with "

Description

the housing 1 has drain ports, and in its middle part a fitting 7 is placed, on which a supply flexible hose 8 is put on to be connected to the supply valve of the tank. On the valve 3 is fixed float 9. The upper and lower surfaces of the float are made

This invention relates to sanitary engineering equipment.

The purpose of the invention is to increase the efficiency of the cistern.

FIG. 1 shows the closure device in the closed position, general view; in fig. 2 - the same in the position of release of water; FIG. 3 is a section A-A in FIG. 1; FIG. 4 is a section BB in FIG. 2

The shutoff device for the flush tank consists of a cylindrical body 1, made in the form of a glass, on which is attached the top 2 of the cap, which has a funnel-shaped opening in which the valve 3 moves in the vertical direction, made in the form of a hollow rod.

A drain hole is made in the lower part of the body, in which the spokes 4 have a ribbed rod 5 fixed, which serves to guide when the valve 3 is moved in the axial direction.

In the lower cylindrical part of the housing there are overflow ports 6, and in its middle part there is a fitting 7 pressed together with the housing, on which a flexible hose 8 is put on the power supplies for connection to the supply tank of the tank.

On the valve 3 in its lower part there is a float 9, which is centered | A washer 10. For centering the float 9 is pulled on the washer 10. The upper and lower surfaces of the float are conoidal in shape, with the lower part serving as a locking element of the valve.

In the upper part of the valve 3 there is a lid 11 having a series of overflow holes 12 for overflow

conoidal jurma. The water entering through the nozzle 7. and the hose 8 forms a shock jet that acts on the lower conoidal surface of the float 9, keeping it in the upper position until the final discharge of water from the tank. 4 il.

dy in case of failure of the supply hose 8.

To increase the reliability, the device has two ways to lift the valve 3: with the help of a rod 13 located in the opening of the cover 11, and with the help of a fork 14 J abutting against the flange 15, which protects the lower part of the cover 11, for fastening At the bottom of the flush tank on the housing 1, brackets 16 with holes are provided. In order to prevent the float 9 from sticking to the inner surface of the crack 2, on its upper part there are protrusions 17 about 1 mm high, which form slots dp draining water from the funnel-like part of the krppka 2.

The device works as follows

Using one of these methods, the valve 3 is raised with the float 9, which opens the drain hole of the housing 1. From the moment the flow of the set dose of water begins, it begins to flow through the flexible hose 8 and fitting 7, thus forming a shock jet acting on the lower conoidal surface of the float 9, holding it in the upper end position until the final discharge of a dose of water. When the water level in the tank is lowered, the part of it remaining in the funnel-shaped part of the cover 2, draining into case 5, prevents air from penetrating into it, which in turn prevents the valve from prematurely dropping into the drain hole and thus disrupting the drain mode, 0 This is achieved due to the fact that the capacity of the funnel-shaped part of the krsh: - ki 2 is chosen so that the time for draining water from the funnel to the body

0

five

1 and the time for lowering the water level from the upper edge of the funnel to the upper edge of the windows 6 was the same.

When the descending level of the upper edge of the drain ports 6 is reached, air enters inside the housing 1, while the valve 3 is lowered into the drain opening.
