Abstract
A diverter valve adapted for use in a pneumatic conveying system for transporting bulk materials comprising a housing having a chamber provided with a cylindrical wall, the cylindrical wall having an inlet port communicating with an inlet passageway in the housing and first and second outlet ports communicating with first and second passageways in the housings, respectively, a rotor disposed in the chamber and having a cylindrical wall disposed in opposed relation to the chamber cylindrical wall, the rotor cylindrical wall having first and second ports and an intercommunicating passageway, the rotor ports being spaced apart a sufficient distance whereby upon the rotor being rotated into a first position relative to the housing, the first rotor port will register with the housing inlet port and the second rotor port will register with the first housing outlet port to intercommunicate the housing inlet passageway with the first housing outlet passageway, and upon the rotor being rotated into a second position relative to the housing, the second rotor port will register with the housing inlet port and the first rotor port will register with the second housing outlet port to intercommunicate the housing inlet passageway with the second housing outlet passageway, the rotor cylindrical wall having a groove disposed about each port thereof and an inflatable seal disposed in each of the grooves.
