Abstract
The utility model provides a self-closed, sealed and anti-sludge-return pipe core comprising a pipe core body and an upper cover installed on the body, wherein the body comprises an embedding part, a necking part and a closing part, which are connected in sequence from top to bottom, the upper cover comprises a cover body and a cover eave at the upper end of the cover body, the inside diameter of the cover body is reduced gradually from top to bottom, and the upper cover is inserted into the embedding part of the body through the cover body. The self-closed, sealed and anti-sludge-return pipe core has the beneficial effects of simple structure, easiness for installation, good self-closing and sealing effects, large water flow and capability of preventing backflow of sludge and sewage and upward movement of waste gases.
Description
Technical field
The utility model relates to be prevented returning dirty device field, especially relates to a kind of self-closing sealing and prevents returning dirty tube core.
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 arranged on to 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 bag has effluent, cause the bag closure not tight, cause dirt and sewage to flow backwards, return on dirty gas.
The utility model content
The purpose of this utility model be to provide a kind of simple in structure, be easy to installation, self-closing and good sealing effect, discharge and greatly, can not cause dirt and sewage to flow backwards, a kind of self-closing sealing of returning on dirty gas is anti-returns dirty tube core.
The technical solution of the utility model is:
A kind of self-closing sealing is anti-returns dirty tube core, and comprise the body of tube core and be arranged on the upper cover on body,
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, and the upper orifice of described nesting part is provided with outer eaves, on the external surface of described nesting part, is provided with at least one anti-slip ring, the length of described anti-slip ring cross sectional shape is greater than its height, make the sealing after inserting pipeline of this product tighter, and the scope of application is wider
The upper end of described closing in section and described nesting part go out mouth-shaped and are complementary, and its lower end fits, and joint place is line laminating or face laminating, and the sidewall of described closing in section is cambered surface, and cambered surface can increase the closing force of closing in section,
Described closure is by the elastic film pipe that side is connected and inwall is bonded to each other,
The side wall thickness of described closure is greater than the sidewall wall thickness of described closing in section, and the sidewall of closing in section is thin, when there being current out-of-date, closure easily open and discharge large, the side of closure is thick, makes the closure effect of closure good, not yielding, long service life,
Described upper cover comprises that internal diameter is lid wide at the top and narrow at the bottom, and is arranged on the lid eaves of described lid upper end,
Described upper cover is plugged in the described nesting part of described body by described lid.
Further, the lower end external surface of described closure is provided with the magnetic stripe that two sides are connected and fit, and makes closure effect more guaranteed.
Further, the soffit of described outer eaves is plane.
Further, the upper surface of described outer eaves is plane, arcwall face.
