Butterfly valve |
摘要 |
A butterfly valve has a housing formed from two stamped sheet parts. The shaft of the valve flap is located in shaped-out parts of the housing halves. The two flanges of the housing halves are held together by a clamp, which has an inwardly open, U or V-shaped cross-section and can be secured in articulated manner by two semicircular parts and presses by chamfered inner faces on tori on the flanges. Thus, the valve can be assembled and disassembled by loosening a single screw.
