Abstract
The utility model relates to a dirt-proof overflow-against tube which can prevent a common sewage pipe from back flow. The utility model is composed of a tube body, a floating ball, an inner cover plate, a sewage inlet and a sewage outlet. The utility model is characterized in that the floating ball is positioned in the tube body; a gap is arranged between the floating ball and the inner wall of the tube body; the sewage inlet is positioned at the upper end surface of the tube body; the sewage outlet is positioned at the lower end surface of the tube body; the inner cover plate is arranged at the inner end surface of the sewage inlet in the tube body; the sewage inlet can be clogged by the floating ball from the inner part of the inner cover plate. The utility model has the advantages of simple structure, and convenient installation. The utility model can effectively prevent an indoor common sewage pipe from back flow.
Description
The utility model relates to civilian sewer pipe and prevents the backing up of sewage device, specifically a kind of Dirt-proof overflow-against tube that is connected in the sewer pipe.
Existing civilian pond (as vegetable sink, washing basin etc.), its following water all be direct and sewer pipe joins, or join by flexible pipe and sewer pipe, and when sewer pipe was blocked, sewage was easy to pour in down a chimney in the pond, contaminated environment.
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, to propose a kind of Dirt-proof overflow-against tube, making it can prevent that the sewage in the sewer pipe from upwards pouring in down a chimney.
At the foregoing invention purpose, the utility model adopts following technical scheme: a kind of Dirt-proof overflow-against tube, form by cylindrical shell, ball float, inner cover plate, sewage import and outlet of sewer, its special character is that described ball float is positioned at cylindrical shell, gapped between ball float and the cylinder inboard wall, the sewage import is positioned at the cylindrical shell upper surface, and outlet of sewer is positioned at the cylindrical shell lower surface, inner cover plate is contained in sewage import inner face place in the cylindrical shell, can from interior the sewage import be blocked by ball float.
The utility model is installed between the following mouth of a river and blow-off pipe in indoor pond, the mouth of a river under its sewage import water-accepting tank, outlet of sewer connects blow-off pipe, its operating principle is, after indoor blow-off line (shared blow-off line) stops up, the backing up of sewage overflow enters in this Dirt-proof overflow-against tube, under the effect of sewage overflow pressure, the ball float come-up promotes inner cover plate and blocks the sewage import, and the sewage in the shared blow-off line can not be poured in down a chimney to indoor, when shared blow-off line is unimpeded, ball float descends, and inner cover plate is opened, and the utility model is in normal blowdown situation.
The utility model is simple in structure, and installation and maintenance are convenient, and it has thoroughly solved the deficiency that background technology exists, and can effectively prevent pouring in down a chimney of indoor shared sewer pipe sewage.
Below in conjunction with the accompanying drawing illustrated embodiment, describe the utility model in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the vertical view of Fig. 1.
With reference to accompanying drawing, the utility model mainly is made up of cylindrical shell 1, ball float 2, inner cover plate 3, sewage induction pipe 4 and effluent outfall 5, wherein, cylindrical shell 1 is cylindrical, seal by cover plate its top and bottom, sewage induction pipe 4 is installed on the central cover plate of cylindrical shell upper surface, and sewage outlet pipe 5 is installed in the cylindrical shell lower surface to be departed from the cover plate of center.In cylindrical shell 1, be placed with the ball float 2 of two diameters less than cylinder internal diameter.One side of the other articulated inner cover plate 3 of the inner face of sewage induction pipe 4 in cylindrical shell 1, the another side of inner cover plate 3 is free state, can be placed on the ball float 2.Gasket seal 6 is housed on the inner cover plate 3, the inner port of sewage induction pipe 4 can be blocked.Screen pack 7 is housed in sewage induction pipe 4.
