Abstract
The utility model relates to a novel sewer cover capable of preventing sewage from flowing back, which comprises a filter screen (1), wherein the filter screen (1) is arranged at the top end of a flat cylinder (2), the inner diameter and the outer diameter of the cylinder (2) match with those of a sewer pipe, the middle of the cylinder wall protrudes towards the inside of a cylinder cavity to form a circle of annular projection (3), a sealing tongue (4) is arranged on the lower side of the projection (3), a tongue handle is inlaid into the cylinder wall on the lower side of the projection (3), the sealing tongue (4) can be opened downwardly by the aid of the tongue handle; a sealing gasket is arranged at the contact position of the sealing tongue (4) with the projection (3), and the sealing tongue (4) closely contacts with the projection (3) to form water sealing under the action of a spring. As the novel sewer cover is provided with the filter screen and the sealing tongue and the sealing tongue can only be opened in one direction, the novel sewer cover can not only filter fragments in the sewage but also prevent the sewage from flowing back, and is simple in structure and high in practicability.
Description
Technical field:
The utility model relates to a kind of sewer lid, especially a kind of building sewer lid.
Background technology:
The sewer lid is located at the sewer mouth; traditional sewer lid is a filter screen normally; can only play a role in filtering; prevent that bigger chip from stopping up sewer; but after other section of sewer is stopped up; sewage takes place from sewer mouth refluence phenomenon in regular meeting, and traditional sewer lid does not prevent the structure that sewage flows backwards, and can not satisfy people's needs.
The utility model content:
The technical problems to be solved in the utility model is: a kind of novel sewer lid that can prevent that sewage from flowing backwards is provided.
For realizing that above-mentioned technical problem the technical solution adopted in the utility model is:
The novel sewer lid comprises filter screen, and filter screen is installed in the top of a flat cylinder, and the interior external diameter of cylinder and the interior external diameter of sewer pipe are complementary; The middle part of cylindrical wall is the outstanding projection that forms a circle annular in the tube chamber, the projection below is provided with a sealed tongue, the tongue handle is embedded in the cylindrical wall of projection below, sealed tongue can be opened downwards by the tongue handle, the contacted position of sealed tongue and projection is provided with sealing mat, and sealed tongue contacts the formation water-stop closely with projection under the effect of spring.
After adopting technique scheme, the beneficial effects of the utility model are:
Because this novel sewer lid not only is provided with filter screen, also be provided with sealed tongue, sealed tongue can only be opened to a direction, so the novel sewer lid can filter the chip in the sewage, can prevent the refluence of sewage again, and simple and practical property is strong.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing 1 is the surface structure schematic diagram of a specific embodiment of this novel sewer lid.
The specific embodiment:
As shown in Figure 1: the novel sewer lid comprises filter screen 1, and filter screen 1 is installed in the top of a flat cylinder 2, and the interior external diameter of cylinder 2 and the interior external diameter of sewer pipe are complementary; The middle part of cylindrical wall is the outstanding projection 3 that forms a circle annular in the tube chamber, projection 3 belows are provided with a sealed tongue 4, the tongue handle is embedded in the cylindrical wall of projection 3 belows, sealed tongue 4 can be opened downwards by the tongue handle, sealed tongue 4 is provided with sealing mat with projection 3 contacted positions, and sealed tongue 4 contacts the formation water-stop closely with projection 3 under the effect of spring.
This novel sewer lid is installed in the entrance of sewer, and after sewage entered, sealed tongue 4 was opened downwards under the effect of hydraulic pressure, and sewage flows into sewer smoothly; When no effluent stream is fashionable, sealed tongue 4 contact closely with projection 3 under the effect of spring and forms water-stops, can prevent the sewage refluence, can prevent that again sewer from returning flavor.
