Abstract
The utility model discloses a sewage pipes prevents counterflow unit, including a barrel that constitutes airtight space, has the baffle in the barrel with airtight space separation into two, there is the circulation clearance between baffle bottom and the barrel bottom the barrel top lies in wherein half the airtight spatial join has an inlet tube the airtight spatial join that the barrel bottom lies in second half has the outlet pipe, and the inlet tube is followed the barrel top and is stretched into and be connected with the duckbill valve among this sewage pipes prevents counterflow unit, and the duckbill valve is opened through rivers gravity, and when stopping the drainage, the duckbill valve is closed, prevents effectively that returning of waste gas or waste water is excessive, and then forms effective the wall, in addition, the clearance of circulating can form the liquid seal bottom the barrel, and the airtight space of two halves forms the air and cuts off, and then forms the two -stage wall, completely cuts off the inlet tube and is connected with the water route between the outlet pipe, effectively prevents the refluence of waste gas waste water.
Description
Technical field
The utility model relates to blowdown apparatus technical field, particularly a kind of blow-off line anti-backflow device.
Background technology
Requiring in higher toilet or sterilizing chamber to air ambient, when the blow-off line of equipment is connected with the sewer pipe of underground, if lack necessary anti-backflow device, the waste gas in sewer pipe or waste water easily flow backwards.At present, existing anti-backflow device complex structure, maintenance inconvenience, be difficult to effectively blow-off line and sewer pipe be cut off.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of blow-off line anti-backflow device that can effectively prevent waste gas waste water from flowing backwards.
For solving the problems of the technologies described above adopted technical scheme: a kind of blow-off line anti-backflow device, comprise the cylindrical shell of a formation confined space, there is dividing plate so that confined space is separated into two halves in described cylindrical shell, passage gaps is there is between described dividing plate bottom and cylindrical shell bottom, the confined space being positioned at wherein half at described cylinder top is connected with water inlet pipe, and the confined space being positioned at second half in described cylindrical shell bottom is connected with outlet pipe.
Further, described outlet pipe stretches into from cylindrical shell bottom and higher than passage gaps.
Further, described water inlet pipe stretches into from cylinder top and is connected with duckbill valve.
Further, the passage gaps distance between described dividing plate bottom and cylindrical shell bottom is 25 ~ 30mm, and the distance that described outlet pipe stretches into from cylindrical shell bottom is 40 ~ 50mm, and described water inlet pipe is 30 ~ 40mm from the distance that cylinder top stretches into.
Further, described cylinder top is provided with the cover with straight-through sight glass, is provided with sealing ring and with bolts between described cylindrical shell and cover.
Further, described cylindrical shell, cover, water inlet pipe and outlet pipe all adopt stainless steel material to make, and described water inlet pipe and cover are welded to connect, and described outlet pipe and cylindrical shell bottom are welded to connect.
Beneficial effect: in this blow-off line anti-backflow device, water inlet pipe stretches into from cylinder top and is connected with duckbill valve, and duckbill valve is opened by current gravity, when stopping draining, duckbill valve is closed, and effectively prevents returning of waste gas or waste water excessive, and then is formed and effectively cut off; In addition, passage gaps can form fluid-tight at cylinder body bottom, and the confined space of two halves forms air partition, and then forms two-stage partition, and isolated water route between water inlet pipe with outlet pipe is connected, and effectively prevents waste gas waste water from flowing backwards.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further;
Fig. 1 is the generalized section of the utility model embodiment;
Fig. 2 is the top view of the utility model embodiment;
Fig. 3 is the scheme of installation of the utility model embodiment.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, a kind of blow-off line anti-backflow device of the utility model, comprise the cylindrical shell 1 of a formation confined space, there is dividing plate 2 so that confined space is separated into two halves in cylindrical shell 1, passage gaps 3 is there is between dividing plate 2 bottom and cylindrical shell 1 bottom, the confined space being positioned at wherein half on cylindrical shell 1 top is connected with water inlet pipe 4, and the confined space being positioned at second half in cylindrical shell 1 bottom is connected with outlet pipe 5.
In the present embodiment, cylindrical shell 1 is bottom end closure, the stainless steel cylinder of open top, cylindrical shell 1 top is provided with cover 6, there is sealing ring to carry out effective sealing to confined space between cover 6 and cylindrical shell 1, adopt with bolts between cover 6 and cylindrical shell 1, be easy to remove and repair, in the middle of cover 6, there is straight-through sight glass 7, observe maintenance to facilitate.
In cylindrical shell 1, middle part is separated by the dividing plate 2 of stainless steel, but not exclusively cut off bottom cylindrical shell 1, namely there is passage gaps 3 bottom cylindrical shell 1, to make the confined space of two halves be connected, wherein, water inlet pipe 4 stretches into from cylindrical shell 1 top and is connected with duckbill valve 8, duckbill valve 8 is opened by current gravity, and when stopping draining, duckbill valve 8 is closed, effectively prevent returning of waste gas or waste water excessive, and then formed and effectively cut off.In addition, outlet pipe 5 stretches into from cylindrical shell 1 bottom and higher than passage gaps 3, to form fluid-tight bottom cylindrical shell 1, the confined space of two halves forms air partition, and then formation two-stage partition.
Wherein, passage gaps 3 distance between dividing plate 2 bottom and cylindrical shell 1 bottom is 25 ~ 30mm, and outlet pipe 5 is 40 ~ 50mm from the distance that cylindrical shell 1 bottom is stretched into, and water inlet pipe 4 is 30 ~ 40mm from the distance that cylindrical shell 1 top is stretched into.
Water inlet pipe 4 and cover 6 adopt and are welded to connect, and outlet pipe 5 and cylindrical shell 1 bottom adopt and be welded to connect, and water inlet pipe 4 adopts ready-package to be connected with the port junction of outlet pipe 5, is convenient to the waterpipe that runs in.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that described technical field those of ordinary skill possesses, various change can also be made under the prerequisite not departing from the utility model aim.
