Description

In order to automatically maintain the working level uniformly, a large mass of water arriving in the HepaBHOMepHON6oflb pool is equipped with siphon outlets, which are automatically quickly discharged to the pool of excess water. Uniform maintenance of a constant working level of the pool water is achieved by placing an additional hole in a special place where the water horizon is completely protected not only from the effects of suction from the main siphon hole, but also from agitation, frosting, etc. the pool to the working level, on which the bottom edge of the secondary siphon visor is located, at the slightest edge detection, atmospheric air is drawn into the resulting gap, entering the siphon and stopping it of action. After stopping the siphon, all the time rising the water horizon, cutting off the bottom edge

the visor stops the entry of air into the additional opening of the siphon, as a result of which the resulting vacuum again turns on the siphon.

In the fixed structures of the above-described siphons, the height of the working level of the basin cannot be precisely adjusted according to the operational mode with the desired exact increase or decrease, without the corresponding rearrangement on the way the siphon took, the lower edge of which determines the working water level of the pool.

The proposed siphon drainage fixture is designed to allow the water level in the pool to be adjusted while the siphon is in progress using simple operations.

Shown in the longitudinal section of the drawing is a device for a siphon drainage system consisting of a screw 2 moved in height, tilted over the water surface, a cap /, hermetically covering, at contact with the underlying surface of the water, an additional opening of an air siphon tube, the end of which is bent upwards and extends below the cap /. at the level of the maximum desired basin water level.

. The rise of the water level in the basin will occur until such time that the visor of the pool comes into contact with the lower edges of the water. In this way, the access of atmospheric air to the additional opening of the siphon pipe will be closed, which will cause, due to the vacuum created in the siphon, an enhanced spillway, which will quickly lower the level of the pool water.

The lowering of the water horizon in the pool will take place until

there is no gap between the lower edge of the cap / and the surface of the water does not reach the lower horizon. Air is drawn into the resulting gap by siphon vacuum to neutralize the vacuum and thereby stop the action of the siphon.

The subject matter of the invention.

Adaptation to the siphon inlet for adjusting the height of the upstream, corresponding to turning the siphon into operation or shutting it down, with the help of an additional pipe and rebuilding parts, which serve to abolish or resume access of air to this pipe during fluctuations in the upstream level, using the cap 7 attached to the bottom hole screw 2 above the upturned end 3 of the additional siphon pipe.
