ROTATABLE WEDGE CARTRIDGE VALVE MECHANISM AND METHOD FOR ASSEMBLY AND DISASSEMBLY

摘要

A rotatable wedge cartridge valve has a cartridge body defining a cartrid ge chamber of a defined internal width having flow ports in communication wi th the cartridge chamber. A rotatable wedge valve cartridge assembly is remo veably positioned within the cartridge chamber and has a controllable width. A core member defines a flow passage and has a spherical outer surface port ion. A valve seat is located within the cartridge chamber. A rotatable wedge valve member is mounted for rotation relative to the core and has a concave surface portion in rotary guided relation with the spherical outer surface. The rotatable wedge valve member also has an external convex surface that i s positioned for sealing engagement with the valve seat and has a geometry d eveloping a non-uniform wall thickness along the rotatable wedge valve membe r.
