"Shut-off device, especially for liquids"

The invention relates to a shut-off element with a slightly tapering shut-off body, which is in the manner of a slide is guided approximately perpendicular to the direction of flow of the housing and is covered with a cover made of a flexible material places openings in front of the housing and its drive parts are sealed against the medium flowing through.

The termination of the medium against the moving parts of the drive can be done by a corrugated tube made of elastic material, or by a rigid cylinder with the closing element is adjusted using an additional sealing insert.

The object of the invention is the closing organ in such a way train that it can be used for medium or higher pressures without the need for an additional sealing insert. Will the closing element is made of rubber or a flexible material such as synthetic rubber and the like, so it is chemical resistant and sufficiently elastic, but not enough

According to the invention, the tubular closing organ, which is angled like a collar at its ends, is made of a smooth one cylindrical or conical tube made of solid but under corresponding Load stretchable plastic, such as Vulcanol, is made. As a result of its smooth shape, there is such a connector much more resistant to external pressure than a corrugated pipe-like body, especially when the valve is normally opened and the closing body is undamaged as a result.

Another possible embodiment of the invention is that a type of metal hose is used as the closing body can, whose helical reinforcement is a relatively has great axial movement, while the actual seal by a relatively thin elastic Coating is achieved on the outer surface of the reinforcement, or through a thin but stretchable covered tube. The metallic reinforcement can with rubber, plastic or the like. encased be.

Finally, according to the invention, the closing body can also consist of two telescopically slidable cylinders made of hard Material or rubber, preferably plastic, exist that unta? stand a certain tension and thus seal properly.
