Description
Technical Field
The utility model relates to a pipeline interface technical field especially relates to an interface structure for different pipe connections.
Background
The flange is used for connecting parts which are connected with each other when the pipeline is connected and is positioned at the pipe end, and the upper part of the flange is provided with holes for penetrating bolts so that the flanges are tightly connected. The flange pipe fitting can be formed by pouring or by threaded connection or welding, and the flange deforms through the nut and the gasket after the nut is screwed down and the specific pressure on the surface of the gasket reaches a certain numerical value, and fills up the uneven part of the sealing surface.
The flange sealing mode mainly comprises: the plane sealing surface is suitable for medium with small pressure and is non-toxic; the concave-convex sealing surface has higher applicable pressure; and the tongue-and-groove sealing surface is suitable for inflammable, explosive and toxic media and has higher pressure.
At present, in the municipal aspect, the technology for connecting pipelines by using flange plates is mature, but the connection requirement of a vertical pipe and a vertical pipe is increased in development, and the conventional flange interface is not suitable for the change of scenes; when the flange is used for connecting the three-way connector, the functionality of the flange is weak.

(II) technical scheme
In order to achieve the above object, the utility model discloses a main technical scheme include:
an interface structure for connection of different pipes, comprising: the flange plate body, the medium discharge orifice has been seted up at the center of flange plate body, a terminal surface extension in medium discharge orifice is formed with the side and connects the body, the top of side connection body upwards extends and is formed with the hi-neck body of outside slope.
Further, the wall thickness of the high-neck pipe body gradually transits to the wall thickness of the side connecting pipe body along the height direction.
Furthermore, a plurality of bolt holes are formed in the flange plate body, and the bolt holes are distributed in an annular array mode by taking the medium overflowing holes as circle centers.
Furthermore, a reinforcing boss is formed between the end part of the side connecting pipe body and the end face of the medium overflowing hole.
Furthermore, the outer wall of the side connecting pipe body is provided with interface grooves.

Detailed Description
For a better understanding of the present invention, reference will now be made in detail to the present invention, examples of which are illustrated in the accompanying drawings.
The utility model discloses an interface structure for different pipe connections of an embodiment, as shown in fig. 1, fig. 2, it includes: the flange plate body 1, the medium overflow hole 11 has been seted up at the center of flange plate body 1, be equipped with a plurality of bolt holes 12 on the flange plate body 1, a plurality of bolt holes 12 use the medium overflow hole 11 to be the annular array mode distribution as the centre of a circle, can make the flange plate locking force when connecting more even.
Specifically, a side connection pipe body 2 is formed to extend from one end surface of the medium overflowing hole 11, and a reinforcing boss 3 is formed between the end portion of the side connection pipe body 2 and the end surface of the medium overflowing hole 11 in order to more stably connect the end portion of the side connection pipe body 2 and the end surface of the medium overflowing hole 11.
Specifically, the top end of the side connecting pipe body 2 extends upwards to form a high-neck pipe body 4 which inclines outwards, the wall thickness of the high-neck pipe body 4 gradually transits to the wall thickness of the side connecting pipe body 2 along the height direction, and the discontinuity of stress is improved, so that the strength of the flange plate is increased; the flange plate is not easy to deform and has good sealing performance.
Further, in order to facilitate connection, the outer wall of the side connection pipe body 2 is provided with connector grooves 21.
In implementation, as shown in fig. 3, two interface structures are prepared, when the first interface structure is installed, a connecting hole 91 is formed in the main pipe 9, the size of the connecting hole 91 is not smaller than the pipe diameter of the side connecting pipe body 2, the side connecting pipe body 2 and the main pipe 9 are welded through the hole opening, the weld joint should reach certain strength, and the relevant regulations of the weld joint of the main pipe 9 are met;
secondly, matching the flange plate of the second interface structure with the flange plate of the first interface structure, connecting the two flange plates by using bolt holes 12 of the two interface structures through bolts 8, enabling the two flange plates to generate deformation after the specific pressure on the surfaces of the gaskets reaches a certain value after the nuts and the gaskets are screwed down, filling up the uneven positions of the sealing surfaces, and sealing the two flange plates by using the gaskets; then, the connector groove line 21 on the side connecting pipe body 2 of the second connector structure is connected with the plastic branch pipe of the groove line with the corresponding specification of the outer side belt 7, and the water stop belt 10 is arranged at the connector to fill the hole and stop water effectively.
The utility model discloses a but interface structure wide application in municipal traffic engineering, building engineering etc. interface structure uses the seal, scour resistance and the durability that have not only greatly improved the pipeline interface, effectively adapts to the pipeline of different materials and pipe diameter simultaneously, has good adaptability.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
