Abstract
The utility model discloses a drainage pipeline joint, which comprises two cast iron pipe ends, wherein one cast iron pipe end is provided with a bell end, and the other one is provided with a corresponding spigot; the spigot is inserted into the bell end. The bottom end inside the bell end is provided with a plane for the top end of the spigot to press against; the bottom end outside the spigot is provided with a plane for the top end of the bell end to press against; the contact positions of the respective top ends and the planes which the top ends are respectively pressed against are provided with sealing rubber rings; and the inside surface of the pipe wall of the bell end and the outside surface of the pipe wall of the spigot are correspondingly provided with positioning convex rings which are clamped with each other in a sliding mode. Compared with the prior art, the utility model has the advantages of simple structure, convenient installation and maintenance, great reduction of production cost, complete avoidance of leakage by arranging two sealing rubber rings at the positions of the bell end and the spigot, convenient and rapid clamping by correspondingly arranging the positioning convex rings which are clamped with each other in a sliding mode on the inside surface of the pipe wall of the bell end and the outside surface of the pipe wall of the spigot and ingenious design.
Description
Technical field
The utility model relates to a kind of pipeline field, relates in particular to a kind of drainage pipe interface.
Background technology
At present, employed drainage pipe interface on the domestic market, be mainly the flexible interface cast iron pipe that bell and spigot formula flange connects, during this product maintenance cost, can't guarantee non-leakagely, and annex is too many, no matter is from making processing or from installing, all increase certain degree of difficulty, also improved the cost of product simultaneously.
The utility model content
In view of this, technical problem to be solved in the utility model is: provide a kind of installation and maintenance the convenient and low drainage pipe interface of cost.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of drainage pipe interface, the termination that comprises two cast iron pipes, wherein, one in two described cast iron pipe terminations has bellmouth, another has corresponding socket, described socket inserts in the bellmouth, the bottom is provided with the plane for the top butt of socket in the described bellmouth, the outer bottom of socket is provided with the plane for the top butt of bellmouth, top separately is provided with O-ring seal with the plane contact place of butt separately, and corresponding being equipped with slided fixing positioning convex ring each other on the tube wall medial surface of described bellmouth and the tube wall lateral surface of described socket.
As preferably, described bellmouth is provided with corresponding screw with the tube wall place of socket, wears according to screw thread in two screws and is bolted with set bolt.
Compared to existing technology, the utility model is simple in structure, and installation, maintenance is convenient, and greatly reduces cost of production; And, avoided the generation of seepage phenomenon fully by being provided with the two seals cushion rubber at bellmouth and spigot; Simultaneously, slide fixing positioning convex ring each other, fix convenient and swiftly, design ingenious by corresponding being equipped with on the tube wall medial surface of bellmouth and socket tube wall lateral surface.
Description of drawings
Fig. 1 is a sectional structure schematic diagram of the present utility model.
The specific embodiment
In order to make those skilled in the art can further understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing.
See also shown in Figure 1, the utility model provides a kind of drainage pipe interface, the termination 1 and 2 that comprises two cast iron pipes, wherein, one in two described cast iron pipe terminations has bellmouth 3, another has corresponding socket 4, described socket 4 inserts in the bellmouth 3, the bottom is provided with the plane 5 for the top butt of socket 4 in the described bellmouth 3, socket 4 outer bottoms are provided with the plane 6 for the top butt of bellmouth, top separately is provided with O-ring seal 7 with the plane contact place of butt separately, and corresponding being equipped with slided fixing positioning convex ring 8 and 9 each other on the tube wall medial surface of described bellmouth and the tube wall lateral surface of described socket.In order to strengthen fastness fixing between bellmouth 3 and the socket 4, described bellmouth also can be provided with corresponding screw with the tube wall place of socket, and interior the wearing according to screw thread of two screws is bolted with set bolt 10.
But the above only is a preferable possible embodiments of the present utility model, is not in order to limit to claim of the present utility model, so the equivalent structure that all utilization the utility model manuals and accompanying drawing content are done changes, all in like manner to be included in the scope of the present utility model.
