Abstract
The utility model provides a sewage-return-proof tube core which comprises a tube core body. The tube core body comprises a nesting portion, a close-in portion and a close portion which are sequentially connected into a whole from top to bottom. The nesting portion is a hollow tube body. The upper end of the close-in portion is matched with the shape of an outlet of the nesting portion. The lower end of the close-in portion is bonding, and the bonding position is line bonding or face bonding. The close portion is an elastic film tube, wherein side edges of the close portion are connected and the inner wall of the close portion is bonding. An outlet of the tail end of the close portion is higher than a lowest position of the tube core body. The sewage-return-proof tube core has the advantages that the structure is simple, dirt articles and dirt water can be prevented from flowing back, and bad air is prevented from returning upwards.
Description
Technical field
The utility model relates to be prevented returning dirty device field, especially relates to a kind of anti-dirty tube core that returns.
Background technology
The sewage drainage pipe of pond of the prior art or toilet drainage position anti-returns dirty structure, adopt trap structure, in the sewer process, dirt can remain in pipe bent position, causes gutter to stop up, sewage is overflowed, use the worry bowl dirt can not be removed fully, trap can only be opened, clear up, but the trap place is narrow, not easy to clean.After adopting a kind of anti-fouling sealing bag for sewer, anti-fouling sealing bag for sewer is installed in pond or toilet drainage position, removed trap, can not cause returning of dirt yet, but existing anti-fouling sealing bag for sewer is an elastic film bag, when card in the bag has effluent, causes the bag closure not tight, cause dirt and sewage to flow backwards, return on the dirty gas.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, simple to operate, production efficiency is high anti-ly returns dirty tube core.
The technical solution of the utility model is: prevent returning dirty tube core, the body that comprises tube core, described body comprises nesting part, closing in section and the closure that is in turn connected into one from top to bottom, described nesting part is hollow tube, the upper end of described closing in section and described nesting part go out mouth-shaped and are complementary, and the lower end fits, and the joint place is that line is fitted or face is fitted, described closure is that side links to each other and inwall elastic film pipe bonded to each other, and the end outlet position of described closure is higher than the lowest positions of described body.
Further, the sidewall of described closing in section increases the closing force of closing in section for facing directly or cambered surface.
Further, described closure is that one section side links to each other and inwall elastic film pipe bonded to each other, the joint place, lower end of the direct and described closing in of its opening section is connected, its exit position is higher than the position, joint place, lower end of described closing in section, perhaps, described closure is that two sections sides that are connected link to each other and inwall elastic film pipe bonded to each other, and one section vertically arranges, the other end arranges the bottom of the elastic film pipe of the vertically section of setting that described closure exit position is higher than along the oblique top of level.After effluent being arranged and reaches constant weight, closure is under the effect of effluent weight, and outlet is sunk and naturally opened effluent is discharged, after the discharge, the closure Natural closure, outlet upwarps and is closed, and has a certain amount of liquid in closing in section, forms fluid-tight, and in the time of can effluent not being arranged because of card in the bag, cause the bag closure not tight, cause dirt and sewage to flow backwards, return on the dirty gas.
Further, the vertical plane of the fitting part, lower end of described closing in section and the central axis of described nesting part are positioned at same vertical plane, perhaps, the vertical plane of the fitting part, lower end of described closing in section is between the vertical plane of the central axis of described nesting part and described closure end outlet position.The sidewall of described closing in section is as stress surface, when the vertical plane of the fitting part, lower end of closing in section is between the vertical plane of the central axis of described nesting part and described closure end outlet position, the stress surface that stress surface is positioned at than the central axis of the vertical plane of the fitting part, lower end of described closing in section and described nesting part in the situation of same vertical plane is large, open so that the end outlet of closure is easier, also make things convenient for according to different effluent weight requirements and discharge complexity and select.
Further, the upper orifice of described nesting part is provided with outer eaves.Outer eaves is so that this tube core is stuck in the entrance of passing away, and the contact surface of outer eaves and passing away fits, so that this tube core can be owing to artificial installing force not be spent greatly, perhaps the discharge water current are excessive causes this tube core to come off and enter passing away.
Further, be provided with at least the projection of an annular on the external surface of described nesting part.When this tube core inserted passing away, the projection of annular arrived the effect with discharge pipe inner wall sealing and chucking, and described projection can be so that this tube core be applicable to the discharge line of more different inner diameters sizes.
