Abstract
The utility model provides a pipeline connecting piece which comprises a first connecting piece, a second connecting piece and a transition surface between the first connecting piece and the second connecting piece, wherein the first connecting piece and the second connecting piece are integrated through the transition surface and are used for sealing connection between two pipelines with the same pipe diameter. The utility model has the beneficial effects that: the transition surface is arranged on the pipeline connecting piece, so that the connecting piece is connected and coated with two pipelines with the same diameter through threads, and a matched connector is added at the joint for sealing and locking, so that the pipeline connecting piece has the advantages of strong sealing performance and difficulty in powder leakage.
Description
Technical Field
The utility model relates to a pipeline connecting piece.
Background
The existing pipeline connection modes for conveying two powdery particle materials with the same pipe diameter are as follows:
the first flange connection is realized by welding flanges at two ends of a pipeline and locking the flanges with gaskets, so that the two pipelines with the same diameter are connected; the second pipeline connector is connected in a mode that two pipelines with the same pipe diameter are directly locked and connected by utilizing the pipeline connector. Its disadvantages are poor sealing performance and easy leakage of powder.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects pointed out by the prior art, the utility model provides the pipeline connecting piece which has the advantages of strong sealing performance and difficulty in powder leakage. The method is realized by the following scheme:
the utility model provides a pipeline connecting piece, includes first connecting piece, second connecting piece and transition face between the two, first connecting piece passes through transition face with the second connecting piece and forms an organic whole for sealing connection between the pipeline of two same pipe diameters.
Furthermore, the first connecting piece is provided with an external thread, the second connecting piece is provided with an internal thread, and the pipe diameter of the first connecting piece is smaller than that of the second connecting piece.
Furthermore, a matching connector is arranged outside the pipeline connecting piece.
Furthermore, a containing cavity is arranged inside the matched connector and used for containing a second connecting piece and a transition surface of the connecting piece.
Further, the transition surface is an inclined surface, a vertical surface or an arc surface.
The utility model has the beneficial effects that: the transition surface is arranged on the pipeline connecting piece, so that the connecting piece is connected and coated with two pipelines with the same diameter through threads, and a matched connector is added at the joint for sealing and locking, thereby achieving the effects of strong sealing performance and difficulty in powder leakage.

Fig. 1 is a schematic view showing a connection manner of a pipe connection member according to an embodiment of the present invention.
Detailed Description
The present invention is further illustrated by the following examples, which are only a part of the examples of the present invention, and these examples are only for explaining the present invention and do not limit the scope of the present invention.
As shown in fig. 1, a pipeline connecting piece comprises a first connecting piece 1, a second connecting piece 2 and a transition surface 3 between the first connecting piece and the second connecting piece, wherein the first connecting piece 1 and the second connecting piece 2 are integrated through the transition surface 3 and are used for sealing connection between two pipelines (4, 5) with the same pipe diameter.
In this embodiment, the first connecting member 1 is provided with an external thread, the second connecting member 2 is provided with an internal thread, and the pipe diameter of the first connecting member 1 is smaller than the pipe diameter of the second connecting member 2.
Specifically, the first connecting piece 1 is connected with a corresponding thread arranged inside the first pipeline 4 and is arranged inside the first pipeline; the second connecting piece 2 is connected with the corresponding thread arranged outside the second pipeline 5 in a wrapping mode, when powder materials flow in from the second pipeline, the powder materials flow into the first pipeline through the inner wall of the connecting piece, and the problem that powder leaks from the traditional connecting piece is solved.
In this embodiment, the outside of the pipe connection is further provided with a mating connector 7, and the top of the mating connector 7 is provided with 2 bolts 6 for locking connection with the first pipe 4 and the second pipe 5 respectively.
In this embodiment, the mating connector 7 is provided with a receiving cavity 8 inside for receiving the second connector 2 and the transition surface 3 of the pipe connector.
In the present embodiment, the transition surface 3 is an inclined surface, a vertical surface or an arc surface, and the transition surface 3 is integrally formed with the first connecting member 1 and the second connecting member 2 by welding.
Specifically, when the connector is installed, the first connecting piece 1 and the second connecting piece 2 are respectively in threaded connection with the pipelines (4 and 5) into a whole, the matched connector 7 is sleeved on the periphery of the connector, the connector 7 is adjusted, the accommodating cavity 8 arranged in the connector is enabled to just wrap the second connecting piece 2 and the transition surface 3 of the connecting pieces, and the matched connector 7 is respectively sealed and locked with the pipelines (4 and 5) with the same pipe diameter through the bolt 8 at the top, so that the whole sealing performance is enhanced.
The utility model is characterized in that: the transition surface is arranged on the connecting piece, so that the connecting piece is connected and coated with two pipelines with the same pipe diameter through threads, and a matched connector is added at the joint for sealing and locking, so that the connecting piece has the advantages of strong sealing performance and difficulty in powder leakage.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
