Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model automatic dewatering device for storage tank.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, the utility model discloses a kind of automatic dewatering device for storage tank, comprise a cylindrical shell 1 and be positioned at the upper cover 2 of this cylindrical shell 1 upper end, one ball float 3 is set in this cylindrical shell 1, there is a sewage draining exit 6 bottom cylindrical shell 1, bottom cylindrical shell 1, side has a discharge port, upper cover 2 has inlet point 4 and an exhausr port 5.
Bottom cylindrical shell 1, a dehydration valve 8 is installed at discharge port 7 place of side, and this dehydration valve 8 is fixedly mounted on the outside of discharge port 7 by a flange; A floating lever rod 9 is installed in the bottom of ball float 3, and this floating lever rod 9 is by location supporting rod 10 kinematic support in cylindrical shell 1, and location supporting rod 10 is fixed in discharge port 7, and extends along discharge port 7 inwall long axis direction, and stretches out cylindrical shell 1 inwall and floating lever rod 9 is hinged; Floating lever rod 9 is positioned at a front end also hinged valve shaft pipe link of floating lever rod 9 and location supporting rod 10 hinged place, and this valve shaft pipe link can drive it to move, and realizes closedown and the opening action of dehydration valve 8.
