Replaceable element for repairing of valve in hydrant, has conical seat surface formed at upper part and co-acting with cylindrical section as replacement valve head, where cylindrical section is set at original valve head

摘要

The element has a ring (25) that is set on a conical ring-shaped valve seat (21). The ring comprises a cylindrical tubular shaped lower lying section that is provided in an upper end of a running sheet (11), and an upper part that is designed as a conical section. A conical seat surface is formed at the upper part. The seat surface co-acts with a cylindrical section as a replacement valve head (32), where the cylindrical section is set at an original valve head. The seat surface is designed in a conical ring shape. A periphery of the lower part comprises a winding section (43) or tooth-work.
