An installation frame is arranged above the liquid discharge pipeline 4; a guide ring 19 is arranged on the mounting rack; the lifting rod 14 is embedded in the guide ring 19. And a limiting guide plate 20 is arranged at the lower end of the lifting rod 14 in the sliding groove. The stability of the up-and-down movement is ensured by the cooperation of the guide ring 19 and the limit guide plate 20.
A limiting frame 10 with a horizontal structure is arranged in the tank body 1; a guide plate is arranged on the limiting frame 10; the connecting rod 11 is embedded in the guide plate. The floating ball 9 is guided to prevent the floating ball from shaking.
