Abstract
The utility model relates to a cast iron drain pipe connecting piece, belonging to a connecting piece of a cast iron piece. The cast iron drain pipe connecting piece mainly comprises a connecting pipe fitting used for connecting two cast iron drain pipes. The cast iron drain pipe connecting piece is characterized in that two side wings are respectively arranged at the two ends of the connecting pipe fitting, a flange pressure plate is fixedly connected with the external side of each side wing through a bolt, and two rubber sealing rings are respectively installed between the two side wings and the flange pressure plates. Since the rubber sealing rings can realize sealing and the flange pressure plates are used for tight connection, the flexible connection between the drain pipes and the connecting pipe fitting is realized, the sealing performance is high, the problem of water seepage is effectively solved, the connection is firm, the corrosion resistance is high, the shock resistance is high and the connecting piece can be disassembled and maintained easily.
Description
Technical field
The utility model belongs to the link of ironcasting, is a kind of connection pipe fitting that connects two iron drain-pipes that is exclusively used in specifically.
Background technique
Iron drain-pipe is widely used in the building such as office building, auditoriums, hotels so that its supportive is strong, safe, is the important component part of drainage system.Present iron drain-pipe all adopts bayonet joint, promptly directly is fastenedly connected by bolt or connects by modes such as welding, cement coatings, for being rigidly connected.There are big, the shortcomings such as sealing is poor, easy to leak of installation and maintenance inconvenience, drainage noise.In this external high level, the skyscraper, because the relative storey displacement that earthquake or blast cause often can reach 20mm-40mm, water leakage phenomenon will occur when relative storey displacement reaches 10mm, therefore there is more problem in rigidly connected iron drain-pipe.
Summary of the invention
The purpose of this utility model is to provide a kind of iron drain-pipe link that flexibly connects.
The utility model is achieved in that
The iron drain-pipe link, mainly comprise the connection pipe fitting that connects two iron drain-pipes, it is characterized in that: the two ends of this connection pipe fitting are respectively arranged with flank, and two flanks outside is fixed with the flange platen respectively by bolt, add O-ring seal between two flanks and the flange platen.
After the utility model adopts said structure, the sealing of employing O-ring seal, be fastenedly connected with the flange platen, realized that waste pipe is connected with the soft of connection pipe fitting, have higher sealability, efficiently solve the seepage problem, have fastening, the corrosion resistant effect of connection, anti-seismic performance is strong, is easy to demolition and maintenance.And can effectively deaden drainage noise, improve living environment quality.
Description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
In the accompanying drawing, 1 is that waste pipe, 2 is that connection pipe fitting, 3 is that flank, 4 is that O-ring seal, 5 is that bolt, 6 is the flange platen.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
As shown in drawings, the utility model is the iron drain-pipe link, mainly comprises the connection pipe fitting 2 of cast iron, and connection pipe fitting 2 is used to connect two iron drain-pipes 1 between two iron drain-pipes 1.Two ports of this connection pipe fitting 2 are respectively arranged with flank 3, and along the port extension.Two flank 3 outsides are respectively arranged with on 6, two flanks 3 of flange platen and the flange platen 6 and are respectively arranged with corresponding screw, the two are fixed together by nut, bolt 5 by screw.Add O-ring seal 4 between two flanks 3 and the flange platen 6.For increasing sealability, sealing cushion rubber 4 is provided with wedge-shaped bar, in the bottom in two flank 3 outsides the wedge slot that cooperates with wedge-shaped bar is set, and the wedge-shaped bar and the wedge slot of O-ring seal 4 fit like a glove.
During use, the connection pipe fitting 2 of same specification is arranged between two iron drain-pipes 1, clamps O-ring seal 4 in two flanks 3 wedge slot outward, makes it to fit like a glove, and installs flange platen 6 at last additional, and waste pipe 1 and connection pipe fitting 2 are fixed together.
Claims (2)
1. iron drain-pipe link, mainly comprise the connection pipe fitting (2) that connects two iron drain-pipes (1), it is characterized in that: the two ends of this connection pipe fitting (2) are respectively arranged with flank (3), two flanks (3) outside is fixed with flange platen (6) respectively by bolt (5), adds O-ring seal (4) between two flanks (3) and the flange platen (6).
2. iron drain-pipe link according to claim 1 is characterized in that: the bottom in described two flanks (3) outside is provided with wedge slot, and described O-ring seal (4) is provided with the wedge-shaped bar that cooperates with wedge slot.
