; Description.

1) On the state of the art .

According to my knowledge, and after viewing the display in Hanover, there are already vacuum valves that are installed at the ends of the vacuum lines in a similar way to the valves presented here. However, they are constructed differently in that they can only be used complete with the corresponding shaft. Otherwise, they constantly transport air, which requires energy. The vacuum lines laid in the ground must therefore be provided with high and low points.

' 2) Task .

The aim was to develop a valve that

1. can be operated with or without air supply

2. that it can be installed in existing shafts or domestic sewage treatment plants, so that no expensive shaft construction is required.

The valve should be used especially in wastewater disposal via vacuum sewerage.

3) Solution.

A valve has been developed that works without external energy according to the Archimedes principle, i.e. it uses the free buoyancy of the water. Together with the vacuum in the pipe, it works safely and reliably.

4) Puncture.

As can be seen in Appendix 3, the water first flows into the dosing tank (3) and raises the float pot (5) according to the water level and /»then the valve closes due to the pressure of the buoyancy. As the water level continues to rise, the water enters the float pot

whereby the buoyancy pressure is reduced again. At a point determined by the preload (6), the buoyancy pot begins to sink. This sinking process is accelerated and strengthened by the additional

flooding water from the doiing pan. The sinking depth of the floating pan is limited to approx. 10 cm. In this state, the floating pan is emptied to such an extent that the lower end of the suction pipe remains approx. 5 cm in the water. The constantly increasing buoyancy with emptying and the suction of the vacuum line inevitably close the valve. The frequency of this process depends exclusively on the amount of water. The doiing pan and suction pipe are therefore permanently installed, while the floating pan moves vertically.

5) Building materials«

All components, especially when used in the wastewater sector, are made of acid-resistant, corrosion-free materials.

6) Type of construction .

The individual components can be seen in the drawing (Appendix 3). The dosing tank is rigidly attached to existing walls or to a stand, as is the suction pipe. The floating pot (9) is guided via the rigidly attached valve rod (8). The aeration device is only used to aerate the medium to be pumped in special cases. Both containers, the dosing tank and the floating pot, can also be manufactured in other shapes and dimensions.

7) Application .

The valve is designed especially for the transport of waste water from existing, stationary pits. However, it is also suitable for the transport of other thin-bodied media, especially where a water level must be maintained with almost millimetre accuracy.

The largest area of application is likely to be in the area of wastewater disposal in sparsely populated, rural areas where vacuum disposal already offers advantages*

Claims (4)

Applicant: Herbert" Protection claims. &Lgr; . Vacuum disposal valve- characterized by that it consists of an outer, fixed container located in the water up to the top edge and an inner container that can move vertically by approx. 2 cm and is guided by a valve rod located in the suction pipe, whereby the inner container has a diameter of approx. 3/4 of the outer container and is preloaded with a preload of concrete, stone or iron or something similar to such an extent that it sinks up to 1/4 of its own height into the liquid in the outer container and thus floats in it without direct contact with the outer container. 2. Vacuum disposal valve according to claim &igr; characterized in that that it is circular, rectangular or square in shape. 3. Vacuum disposal valve according to claim 1 and 2, characterized in that that the seal in the valve housing is made of rubber or similarly elastic plastic and is designed as a ball or flat seal and is replaceable, 4. Vacuum disposal valve according to claim 1 to 3» characterized in that that the centrally arranged intake pipe is provided with the valve housing with a side outlet at the upper end and that an air pipe with a metering screw at the top is attached to the side of the intake pipe.
