Abstract
The utility model discloses a device preventing odorant and sewage water backflow, in particular to an anti-overflow floor drain which comprises a pipe with a column-shaped chamber interface and an air backflow preventing cover which is arranged inside the column-shaped chamber interface, and is covered on the convex end of the pipe, and has a flow-through gap with the column-shaped chamber interface, a floor drain valve sealed with the pipe internal chamber is fixed inside the pipe, the floor drain valve is a column-shaped structure, an upper end cover with a round-shaped water inlet is fixed on the upper end of the floor drain valve, while a drop stopping plate provided with a through-hole or a gap is arranged on the lower end, a floating ball is arranged in the chamber of the floor drain valve, the round-shaped water inlet is provided with a joint surface matching tightly with the outer surface of the floating ball. The utility model has simple structure, low cost and easy popularization, which can not only prevent the backflow of dirt air, but also prevent the backflow of sewage water.
Description
Affiliated technical field
The utility model relates to device a kind of deodorization and that bilge water resisting refluxes, particularly a kind of anti-overflow floor drain.
Technical background
Existing floor drain, comprise the pipeline of column cavity interface and place in the column cavity interface and be buckled in the top of pipeline jag, and and there is the anti feedback in circulation slit to cover between the described column cavity interface, when this floor drain uses on building, if generation line clogging, sewage will come out to enter in the resident family of lower floor from floor drain, not only cause resident's property loss, also have a strong impact on neighborhood relationship.
Summary of the invention
At existing problem in the above-mentioned prior art, the utility model provides a kind of anti-overflow floor drain, and it not only can play the effect of anti-foul smell, can also prevent sewage backflow.
The technical scheme that the utility model adopted is this kind anti-overflow floor drain, comprise the pipeline of column cavity interface and place in the column cavity interface and be buckled in the top of pipeline jag, and and there is the anti feedback in circulation slit to cover between the described column cavity interface, it is characterized in that described pipeline in be fixed with floor drain valve with inner cavity of pipe sealing, described floor drain valve is a column structure, the upper end is fastened with the upper end cover with circular water inlet, the lower end is provided with the falling stop plate in band through hole or slit, be equipped with ball float at the floor drain valve insertion, described circular water inlet has the bonding surface that is sealed and matched mutually with the ball float external surface.
Further, described floor drain valve and inner cavity of pipe are by seal ring seal or pass through thread seal; Can also be provided with a pair of pin symmetrically in described floor drain valve appearance, be provided with the inner convex platform of the band L type groove that matches with pin, the appearance sealing of the bottom of this inner convex platform and floor drain valve at inner-walls of duct.Can be to described pipeline jag for being fixed on the upper end of the floor drain valve in the pipeline.
The beneficial effects of the utility model are that the ball float come-up has prevented sewage backflow with circular water inlet sealing when line clogging, has avoided the loss and the dispute that cause thus owing to be provided with ball float in the floor drain valve.The anti feedback lid can prevent that dirty gas from refluxing.And simple in structure, cost is low, is easy to promote.
Description of drawings
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the sectional view of the utility model first embodiment;
Fig. 2 is the sectional view of the utility model second embodiment.
Among the figure, 1-column cavity interface, 2-anti feedback lid, 3-upper end cover, 4-pipeline jag, 5-joint ring, 6-pipeline, 7-ball float, 8-falling stop plate.
The specific embodiment
Embodiment shown in the accompanying drawing 1 is the structure that the utility model is transformed the pipeline floor drain of existing building.In the present embodiment, this kind anti-overflow floor drain, comprise the pipeline 6 of band column cavity interface 1 and place in the column cavity interface 1 and be buckled in the top of pipeline jag 4, and and there is the anti feedback in circulation slit to cover 2 between the described column cavity interface 1, generally speaking, sewage enters pipeline 6 by the circulation slit between column cavity interface 1 and the anti feedback lid 2 and flows out, and anti feedback lid 2 has the effect that prevents that dirty gas refluxes in the pipeline 6.Be fixed with floor drain valve in the inner chamber of described pipeline 6 with the inner cavity of pipe sealing, this floor drain valve is a column structure, the upper end is provided with the upper end cover 3 with circular water inlet, and this upper end cover 3 is by the external screw thread secure fit on internal thread and the floor drain valve, and this purpose is to change easily ball float 7; The lower end is provided with the falling stop plate 8 with a plurality of through holes or slit, is equipped with hollow float 7 at the floor drain valve insertion, and this ball float 7 is movable between falling stop plate 8 and upper cover plate 3.Described circular water inlet have with the ball float external surface be sealed and matched mutually in conjunction with the conical surface.Ball float 7 can move with liquid level between falling stop plate and upper end cover to the greatest extent.Described floor drain valve and inner cavity of pipe are by rubber seal ring 5 sealings.
When line clogging, the sewage level height rises, and ball float also rises to the circular water inlet conical surface on the upper end cover 3 thereupon and combine and sealing, thereby reaches the purpose of bilge water resisting backflow.
The pipeline drain structure that embodiment shown in the accompanying drawing 2 uses on newly-built building for the utility model.In the present embodiment, floor drain valve and pipeline 6 inner chambers pass through thread seal, can also be provided with a pair of pin symmetrically in described floor drain valve appearance, be provided with the inner convex platform of the band L type groove that matches with pin, the appearance sealing of the bottom of this inner convex platform and floor drain valve at inner-walls of duct.Described pipeline jag 4 can be for being fixed on the upper end of the floor drain valve in the pipeline.Other aspects are same as the previously described embodiments, repeat no more.
Claims (5)
1, anti-overflow floor drain, comprise the pipeline of column cavity interface and place in the column cavity interface and be buckled in the top of pipeline jag, and and there is the anti feedback in circulation slit to cover between the described column cavity interface, the inner chamber that it is characterized in that described pipeline is fixed with the floor drain valve that seals with inner cavity of pipe, described floor drain valve is a column structure, the upper end is fastened with the upper end cover with circular water inlet, the lower end is provided with the falling stop plate in band through hole or slit, be equipped with ball float at the floor drain valve insertion, described circular water inlet has the bonding surface that is sealed and matched mutually with the ball float external surface.
