Title: BALL VALVE FOR FERMENTATION TANK AND FERMENTATION TANK HAVING BALL VALVE
Abstract:
A ball valve for a fermentation tank and a fermentation tank having the ball valve. The ball valve (100) comprises: a body (10), inside of which a chamber (11) is enclosed and a first inlet (12) and a first outlet (13) are provided, the side wall of the body (10) being provided with a liquid discharge port (14); a ball (20), rotatably provided in the chamber (11) of the body (10) and provided therein with a flow channel (21) which passes through the ball, both ends of the flow channel (21) respectively forming a second inlet (22) and a second outlet (23), a gap being formed between the ball (20) and the inner wall of the chamber (11); a rotation mechanism, configured such that when the ball (20) is positioned in an opening position, the second inlet (22) is in communication with the first inlet (12), and the second outlet (23) is in communication with the first outlet (13); and a cleaning duct (70), both ends of which respectively form a third inlet (71) and a third outlet (72), the third inlet (71) being connected to the side wall of the body (10) at the first inlet (12) so as to be in communication with the first inlet (12), the third outlet (72) being connected to the side wall of the chamber (11) of the body so as to be in communication with the chamber (11). The inside of the ball valve can be thoroughly cleaned without disassembling the ball valve; moreover, the waste liquid left over from washing can be discharged via the liquid discharge port, preventing the fermentation tank from becoming polluted.
