Description

The innovation relates to a check valve with an essentially elastic material, such as rubber, existing flap body. It is concerned with the solution to the problem of bringing an advantageous design of components of such valves. Another purpose of it is to be able to attach the renewal _s contemporary door body for the exchange without special conversion even where previously solid metallic, pivoting around a shaft Klappenlcörper were used.

Check valves ρ where the valve body forming elastic material that allows pivoting movement, that is to say serves as a G-joint or hinge, are known. you will be usually held with its upper part by a bracket on the housing. The actual flap part is through a metallic one Plate reinforced on the back. It has been shown in this design that the sharp edge of the metal both from the bracket as well as from the plate after a larger number of folding movements the elastic material more or less strongly damaged. Furthermore, calibration shows a disadvantage that the valve body not fastened along the entire reversible edge is, so that a one-sided opening and closing takes place and therefore the aforementioned damage occurs to an increased extent.

After the hiring, the flap of the check valve should now be like this Be designed that the valve body on a surface of the
