Construction and assembly can be conveniently carried out, the sewage draining assembly is directly transported to a laying fixed point after being prefabricated, produced and formed in a factory, the construction time is shortened, and in the using process, the sewage draining assembly can assist in pipeline dredging, and waste impurities are prevented from being accumulated in a pipe body to cause pipe body blockage.

The invention relates to the technical field of pedestal pans, and discloses a water-saving pedestal pan which comprises a flushing part, an accelerating part, a sewage discharging part and a sewage discharging pipe which are sequentially communicated, at least one flushing opening is formed in the rear portion of the flushing part, the width of a water sealing surface at the top of the sewage discharging part is gradually reduced from back to front, and / or at least one boss is arranged on the inner wall of the accelerating part. The slope portion of the boss can play a role in guiding water flow passing through the slope portion, force facing the pollution discharge portion is applied to the part of water flow, and part of water flow is directly guided to the pollution discharge portion, so that water flow rushing to the pollution discharge portion from top to bottom along the inner wall of the acceleration portion is formed under the interaction of the water flow and other water flow. And the part of water flow can generate direct larger impact force on the dirt floating on the water sealing surface and the dirt in the dirt discharge part, so that the dirt can be discharged more easily.

The present invention relates to a time-delayed slow-closing control valve with a sewage discharge function, comprising a valve body, a valve seat, a valve disc and a valve stem, wherein the valve seat is mounted inside the valve body, the valve disc is mounted on the valve stem, and further comprises a spring and a valve cover with a cavity, the valve stem can be relatively slidably mounted on the valve seat, the valve disc is subjected to a preset spring preload force to form a sealing pair with the valve seat, the valve cover is mounted on the valve body, and a diaphragm is provided between the valve cover and the valve body, the valve disc is mounted on the lower side of the diaphragm and can be subjected to the pressure of a medium inside the valve cover cavity, a bypass pipe connecting the valve cover cavity and the valve body inlet end is provided between the valve cover and the valve body, and a sewage discharge bypass pipe is provided on the valve cover.

The utility model belongs to the technical field of facility fishery breeding, and particularly relates to a circular fishpond breeding system. The actual activity range of fish can be increased, and the discharge effect of solid pollutants such as fish excrement and feed residues in the fishpond can be improved. The water distributor is inclined upward along the direction from the center of the circular fishpond to the edge, drives the upper water body to flow along the direction from the center of the circular fishpond to the edge, and makes the upper water body flow downward at the arc-shaped flow guide section. The lower water body of the circular fishpond flows along the bottom wall to the center of the circular fishpond. Part of the lower water body of the circular fishpond and part of the solid pollutants flow along the bottom wall, and are finally discharged from the sewage outlet. Another part of the lower water body of the circular fishpond flows upward along the outer wall of the vertical drainage pipe, enters the vertical drainage pipe from the upper end of the vertical drainage pipe through the drainage channel, flows vertically downward in the vertical drainage pipe, and is finally discharged from the sewage outlet. Another part of the solid pollutants is discharged from the sewage outlet along the water flow.
