TOILET BOWL DISCHARGE VALVE ASSEMBLY

摘要

Disclosed are trap valve assemblies for controlling flow from a toilet bo wl to a trap way. In one form there is a cartridge unit positionable immedia tely below a toilet bowl discharge outlet. It has a pivotable gate in a form of a spherical segment. The gate has an eccentric pivoting motion so that i t can swing from an open position to a blocking/closing position in which it fully contacts a sealing gasket. The spherical segment has a leading edge w hich is approximately between +40° and -40° from vertical when the gate is i n an open position, to minimize the energy required to close the gate. In an other form a ball and socket connection to the gate valve facilitates sealin g.
