Abstract
The utility model provides a dirt return prevention connecting pipe, which includes a sewer dirt prevention sealing bag and an expansion liner tube inserted into the sewer dirt prevention sealing bag, wherein the sewer dirt prevention sealing bag includes an annular pipe body, a transitional part integrated with the annular pipe body and an elastic film bag body integrated with the transitional part; the opposite films of the elastic film bag body are closely attached, and two folded lines are formed on the two sides of the elastic film bag body; and the expansion liner tube includes a tube body, an annular platform arranged at the upper end of the tube body and expanding pieces arranged at the lower end of the tube body. The utility model has the benefits that the dirt return prevention connecting pipe has a simple structure, is simple to operate, can prevent slipping off, and can adjust flow rate.
Description
Technical field
The utility model belongs to anti-and returns dirty device, especially relates to a kind of anti-dirty adapter of returning.
Background technology
Pond of the prior art sewage drainage pipe anti-returns dirty structure, adopts the trap structure, in the sewer process; Dirt can remain in bend, causes gutter to stop up, and sewage is overflowed; Use the worry bowl can not dirt be removed fully, can only trap be opened, clear up; But the trap place is narrow, not easy to clean.After adopting the antifouling sealing bag of a kind of sewer, the antifouling sealing bag of sewer is enclosed within the outlet of the inlet of sewer or gutter, removed trap; Also can not cause returning of dirt, but the antifouling sealing bag of existing sewer is an elastic film bag, just that one section opening support is big in use; Be enclosed within on gutter or the sewer mouth, the antifouling sealing bag of sewer occur through regular meeting and come off, cause the sewer phenomenon of blocking; And the bag length of the antifouling sealing bag of existing sewer can't be adjusted after use; The prominent drain discharge of meeting has part of contaminated water row and does not go out bigger the time, and the phenomenon that flows out from the inlet of sewer.
Summary of the invention
The purpose of the utility model provide a kind of simple in structure, simple to operate, prevent to come off, flow is adjustable anti-ly returns dirty the adapter.
The technical scheme of the utility model is: a kind of anti-dirty adapter of returning comprises antifouling sealing bag of sewer and the expansion bushing pipe that is plugged in the antifouling sealing bag of said sewer.Expand tubing and can pass through the antifouling sealing bag bag of appropriate change sewer water-sealing part length, change the displacement of the antifouling sealing bag of sewer.
The transition part that the antifouling sealing bag of said sewer comprises annular body, connect as one with said annular body, the elastic film bag that links into an integrated entity with said transition part; Said elastic film bag opposite film is close together, and both sides form twice backfin line.Realize sealing through the film that is close together each other, after in the antifouling sealing bag of sewer current being arranged, the tension force reason owing to water between the film can form moisture film, and moisture film can not evaporate for a long time, has guaranteed sealing effectiveness, makes dirt etc. to return.
The external side of said ring pipe is provided with some annular protrusions.When the antifouling sealing bag of sewer inserted sewer, annular protrusion arrived the effect with sewer pipe inner wall sealing and chucking.
Said annular body upper end is provided with annular lip.Annular lip makes the antifouling sealing bag of sewer be stuck in the entrance of sewer, makes that the antifouling sealing bag of sewer can be owing to artificial installing force not be spent greatly, descends perhaps that the water current are excessive to be caused the antifouling sealing bag of sewer to come off and get into sewer.
Said expansion bushing pipe comprises body, be arranged at the ring-shaped platform of said body upper end and be positioned at the expanding plate of said body lower end.The expansion bushing pipe is protected the effect of the antifouling sealing bag of sewer in addition; When gutter plugs in the antifouling sealing bag of sewer repeatedly; The expansion bushing pipe prevents that effectively the antifouling sealing bag of sewer from being damaged by gutter, prolongs the application life of the antifouling sealing bag of sewer, reduces the trouble of changing the antifouling sealing bag of sewer; The convenient on the one hand expansion bushing pipe of ring-shaped platform is installed in the antifouling sealing bag of sewer; On the other hand the antifouling sealing bag of sewer further is stuck in inlet of sewer place, prevents that further the antifouling sealing bag of sewer from coming off, expanding plate is used to enlarge the opening of the antifouling sealing bag of sewer upper end; Making has the pocket portion of water seal to shorten, and makes the flow of the antifouling sealing bag of sewer become big.
Said expanding plate is two, and said expanding plate is taper seat or round table surface one section.The periphery of expanding plate is taper seat or round table surface, makes that the expanding plate outer wall is the circular arc transition, does not have water caltrop, prevents to be damaged the seal failure problem that causes by expanding plate because of the antifouling sealing bag of sewer.
The length of said expanding plate is greater than the length of said transition part.The length of expanding plate is long, can be so that expanding plate be directly expanded the suitable for reading of elastic film bag, and expansion effect is better.

The specific embodiment
As shown in Figure 1, the utility model comprises antifouling sealing bag 1 of sewer and the expansion bushing pipe 2 that is plugged in the antifouling sealing bag 1 of said sewer.
Like Fig. 2, shown in Figure 3; The transition part 4 that the antifouling sealing bag 1 of said sewer comprises annular body 3, connect as one with said annular body 3, the elastic film bag 5 that links into an integrated entity with said transition part 4; Said elastic film bag 5 opposite films are close together, and both sides form twice backfin line 6.
Said annular body 3 arranged outside have some annular protrusions 7.
Said annular body 3 upper ends are provided with annular lip 8.
Like Fig. 4, shown in Figure 5, said expansion bushing pipe 2 comprises body 9, be arranged at the ring-shaped platform 10 of said body 9 upper ends and be positioned at the expanding plate 11 of said body 9 lower ends.
Said expanding plate 11 is two, and said expanding plate 11 is taper seat or round table surface one section.
The length of said expanding plate 11 is greater than the length of said transition part 4.
The course of work of this instance: the antifouling sealing bag 1 of sewer is inserted inlet of sewer place, will expand bushing pipe 2 then and insert in the antifouling sealing bag 1 of sewer, when displacement does not reach the draining demand; To expand bushing pipe 2 takes out; Expanding plate 11 is crooked laterally, insert again in the antifouling sealing bag 1 of sewer, because the distance between two expanding plates 11 is greater than original distance; Make the upper end of elastic film bag 5 open; Thereby make the moisture film water-sealing part in the elastic film bag 5 shorten, make the resistance to water-flow of passing through diminish, increase streamflow.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
