Apparatus for valve installation in a flume

摘要

A valve installation for a flume wherein a preinstalled liner is cast in place at the time of flume construction. The valve body with sealing gasket is later installed within the liner. Wedge plates and associated force-applying bevelled washers are installed around the periphery of the valve body within the cast groove which receives the liner. The bevelled washer can be actuated to force the valve body against a gasket compressing the gasket to form a seal and for locking the valve body in the liner. Removal for servicing is easily accomplished by the removal of the bevelled washers.
