Abstract
The utility model relates to the technical field of pipeline materials, in particular to a backflow prevention sewage draining device. A hollow tubular device with the thick middle, two thin ends and a ball internally arranged in the thick middle is additionally mounted on the lower surface of the wastewater inlet of the original draining device; the lower end of the device is connected with a U-shaped bent pipe; and the highest part of the bent pipe is parallel to one-third part at the lower end of the thick part of the device. When the pipeline is unblocked, wastewater is drained from the circumference of the ball; when the pipeline is blocked, the wastewater flows back, the ball is pushed to a water inlet at the upper part of the device, and the wastewater is stopped below the ball, therefore, the effect of preventing the wastewater from flowing back is effectively achieved. The device has the advantages of simple structure, easy processing, lower cost and wide application range, and has a certain value of popularization and application.
Description
Technical field
The utility model belongs to the pipeline material technical field, specifically is a kind of anti-back flow drainage device.
Background technique
The water inlet of civil building drainage prevents that with U type bend pipe or at a small amount of sparge water of water closet prodelta clay foul smell is excessive usually at present.But when the water main pipe stops up under the residential building layer, upper strata row is rushed down the sewage that gets off and can be broken through the water seal of U type, blows back into tank or indoor, gently then pollutes indoor, influence clean environment, heavy then flow out from entering house door, pollute corridor, cause very burden for this floor, and be penetrated into lower floor from the floor slit, stained body of wall influences circuit, makes troubles for whole unit resident.Therefore, invention is a kind of prevents that the device of sewage refluence is very necessary.
Summary of the invention:
In order to overcome the deficiency of above existence, the utility model provides a kind of anti-back flow drainage device, and this device can effectively prevent particularly flexible contaminants counterflow of sewage.
The technological scheme that the utility model adopted is:
The place installs the anti-back flow drainage device additional at original drainage pipe sewage inlet, this device is suitable for reading slightly to be coarser than former pipeline, former pipeline tail end can be inserted wherein, end opening is slightly less than former U type bend pipe diameter, it is suitable for reading this device tail end can be inserted former U type bend pipe, makes the middle thick subordinate of U type bend pipe highest point and this device hold 1/3rd places parallel; Thicker between this device upper and lower opening, a wherein built-in ball, when pipeline was unimpeded, sewage flowed out by device around ball from top to bottom; When pipeline below was stopped up, because of sewage flows backwards, swimming in ball above the sewage, to be pushed to device suitable for reading, shuts suitable for reading greater than back cut diameter because of the ball diameter, and sewage is blocked under the ball, plays bilge water resisting refluence effect.In effluent stream following time,, ball is floated by water, and sewage flows down around ball; Because slightly the lower end 1/3rd of portion is parallel in the middle of the U type bend pipe highest point that the bottom connects and this device, so guaranteed this bottom of device liquid of having a surplus all the time, ball is in floating condition all the time, can not drop on the outlet port.
The beneficial effects of the utility model are to prevent that effectively sewage from flowing backwards under the prerequisite that does not influence the normal discharging of sewage; And this device only is to have inserted a little ball in the pipeline of pupa shape, simple in structure, be easy to processing, cost is lower, applied widely, has certain application value.
Description of drawings
Accompanying drawing is a sectional structure chart of the present utility model.
Among the figure: 1 top water intake, 2 pupa shape pipes, 3 balls, 4 bottom water outlets.
Embodiment
The utility model is further specified as follows below in conjunction with accompanying drawing:
As shown in the figure, a kind of anti-back flow drainage device is made of top water intake 1, pupa shape pipe 2, ball 3, bottom water outlet 4; Water intake 1 diameter in top is greater than bottom water outlet 4 diameters; Ball 3 diameters are greater than top water intake 1 diameter; Ball 3 places in the pupa shape pipe 2.
When sewage was let out under former drainage pipeline drain opening, sewage flowed directly into pupa shape pipe 2 from this device top water intake 4, flowed down around ball 3, flowed into U type drain pipe from lower outlet 4 at last, entered the main sewer road.When sewage is stopped up can not be unimpeded the time in the main pipe somewhere, last floor row's sewage down flows backwards through lower outlet 4 inflow pupa shape pipes 2 from U type pipe, promote ball 3 and rise to device top water intake 1, because ball 3 materials are softer, the sewage that is flow backwards overlays on this device top water intake 1, the sewage of refluence is blocked in below the ball ball, thereby effectively plays the sewage refluence effect that prevents.
Claims (2)
1. anti-back flow drainage device, comprise top water intake (1), pupa shape pipe (2), ball (3), bottom water outlet (4), it is characterized in that top water intake (1) diameter is greater than bottom water outlet (4) diameter, ball (3) diameter is greater than top water intake (1) diameter, and ball (3) places in the pupa shape pipe (2).
2. a kind of anti-back flow drainage device according to claim 1 is characterized in that the highest point of the U type bend pipe that connects with this device bottom water outlet (4) is parallel with 1/3rd places, pupa shape pipe (2) bottom.
