Description

Technical Field

[0001] The utility model belongs to the technical field of pipe fittings, and in particular relates to a multifunctional pipe fitting for fluid transportation. Background Art

[0002] In the existing field of fluid transportation, pipes that need to be connected across materials and pipe diameters are generally realized in two steps through groove quick connection / flange / thread+reducer / bushing. This method has a large installation space, takes a long time to install, and cannot be used in locations where the installation space is small and the operation of personnel is limited. For this reason, many projects and equipment have to be forced to increase the project height and floor space. Among them, the utility model patent with authorization announcement number CN201003664Y discloses an expanded diameter pipe joint, which specifically discloses the following scheme: one end is a small-diameter pipe interface that is expanded by a diffuser and connected to a large-diameter pipe interface. In the sewer pipe of the house or the horizontal water pipe, the water flow rate obviously increases from top to bottom or from the starting end to the terminal. Therefore, the expanded diameter pipe joint can be installed in sections according to the flow rate to implement the section-by-section expansion of the pipe diameter. Although the pipe joint disclosed in the patent can realize the connection of pipes of different diameters, its connection structure is relatively simple and cannot be applied to the connection between two pipes of different materials, different diameters, different connection methods, different axes, etc. Based on this, it is necessary to design a multifunctional connecting pipe fitting suitable for fluid transportation pipelines. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a multifunctional pipe fitting for fluid transportation. The utility model aims to solve the technical problem that traditional pipe fittings need to be completed twice in succession and solve the technical problem that the installation space is limited and cannot be installed.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A multifunctional pipe fitting for fluid transportation, comprising a front adapter part for connecting to a pipe of different material at the front end, a middle diameter reducing part for realizing pipe diameter conversion connection, and a rear connecting pipe part for connecting to a rear end pipeline, wherein the middle diameter reducing part is located between the front adapter part and the rear connecting pipe part to connect the two together, and the front adapter part, the middle diameter reducing part and the rear connecting pipe part are integrally formed.

[0006] As a further limitation of the above solution, the front transition part adopts a flange transition structure, a groove quick-connect transition structure, or a threaded transition structure.

[0007] As a further limitation of the above scheme, the middle reducing portion is a reducing head structure that can adapt to and transitionally connect with the front transition portions and the rear connecting portion on both sides.

[0008] As a further limitation of the above scheme, the middle diameter reducing portion is in the form of a joint with two ends being concentric and of different diameters, formed by a cylindrical surface and a conical surface.

[0009] As a further limitation of the above scheme, the middle diameter reducing portion is in the form of a joint with eccentric diameter reducing ends formed by a cylindrical surface and an arc surface.

[0010] As a further limitation of the above scheme, the rear connecting pipe portion adopts a socket-and-spigot adhesive connection structure, or a welding connection structure, or a groove quick-connect connection structure, or a flange connection structure, or a threaded connection structure, or a hot-melt connection structure.

[0011] As a further limitation of the above scheme, the front transition part, the middle diameter reducing part and the rear connecting pipe part are integrally formed by machining, casting or 3D printing.

[0012] The advantages of this utility model compared with the prior art:

[0013] 1. This solution combines the front transfer part across materials with the middle diameter-changing part across pipe diameters and the rear pipe part through one-piece molding, realizing the connection of pipes across materials and pipe diameters at the same time, solving the technical problem that traditional pipe fittings need to be completed in two steps; for high-difficulty projects with narrow installation space, it can also solve the technical problem that the installation space is limited and cannot be installed, avoiding the situation where the project height and floor space need to be increased, thereby realizing the pipe transfer efficiently and quickly;

[0014] 2. The one-piece combined pipe joint in this solution can not only realize the connection between two pipes of different diameters with the same central axis, but also realize the connection between two pipes of different diameters with different central axes. It is easy to use and multifunctional. BRIEF DESCRIPTION OF THE DRAWINGS
