Abstract

PURPOSE: A distributing valve for preventing counter flow in a waste gas treatment system is provided to discharge waste gas through a curved discharge pipe, and to restrict counter flow of waste gas by changing the discharge direction with turning a rotating body right and left in operating an actuator. CONSTITUTION: A distributing valve comprises a valve body having an inlet pipe(32) and two curved discharge pipes(34,35), an input hole(33), and a position detecting sensor(64) between the discharge pipe and the inlet pipe; rotary disks(38,39) having shaft housings(36) mounting thrust bearings(48,49) in upper and lower parts; a rotating body(40) having an inlet and an outlet according to position of rotation, and injection holes(41) communicated with the input hole; a flat cover(50) mounting an actuator(60) having a rotating shaft(62) in a through hole(56); and a counter flow restricting unit placed in stepped securing portions in the inlet and the outlet of the rotating body.
