DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0019] like Figures 1 to 5 As shown, the pipeline adjustment connection device is used to connect a pipeline 1 with a ring groove connection end and a pipeline 2 with a flange connection end, wherein the outer surface of the pipeline 1 with the ring groove connection end is provided with at least two ring grooves, and the ring grooves are arranged at a relatively close distance, so as to achieve fine adjustment of the connection position when the two pipelines are connected, which helps to ensure the smoothness of the pipeline connection and the accuracy of pipeline laying. Specifically, this embodiment includes two semi-annular and oppositely arranged pipeline holding connection plates 3, and a pipeline connection sealing ring 4 is sandwiched between the inner arc surface of the two pipeline holding connection plates 3 and the outer wall of the pipeline 1 with the ring groove connection end. When the two pipelines are installed and connected, the pipeline connection sealing ring 4 can form a seal on the connection surface of the two to prevent the leakage of the conveying medium in the pipeline, thereby ensuring the smooth and safe transportation of the medium.

[0020] like Figure 3 and Figure 5As shown, the pipeline connection sealing ring 4 includes a sealing ring body 41 with a teardrop-shaped cross section, an assembly limiting flange 42 extending outward is provided at the upper end of the sealing ring body 41, and a sealing ring groove for accommodating the pipeline connection sealing ring 4 is provided at the bottom end of the two pipeline holding connection plates 3. When the two pipeline holding connection plates 3 are installed and fixed, a certain extrusion force will be formed on the pipeline connection sealing ring 4, so that the thicker part at the bottom of the sealing ring body 41 will be severely deformed to fill the annular groove on the pipeline 1 with annular groove connection end adjacent thereto, which not only realizes the sealing of the two pipeline connection surfaces, but also can further limit and fix the sealing ring body 41 with the help of the annular groove on the pipeline 1 with annular groove connection end, thereby ensuring the sealing effect and assembly fixity of the pipeline connection sealing ring 4.

[0021] A semi-circular pipeline reinforcing holding plate 5 is also connected to the surface of each pipeline holding connection plate 3, and the pipeline reinforcing holding plate 5 is arranged perpendicular to the pipeline holding connection plate 3, and the inner arc surface of the pipeline holding connection plate 3 also abuts against the outer wall of the pipeline 1 with the annular groove connection end. The arrangement of the pipeline reinforcing holding plate 5 increases the contact area between the present embodiment and the pipeline 1 with the annular groove connection end, thereby helping to improve the firmness of the pipeline connection.

[0022] In this embodiment, a pipeline holding and fixing device is detachably provided between the two pipeline reinforcing holding plates 5, and the pipeline holding and fixing device is used for connecting and fixing the two pipeline reinforcing holding plates 5, so that the two pipeline reinforcing holding plates 5 and the pipeline holding connection plate 3 can firmly embrace the outside of the pipeline 1 with the annular groove connection end. The pipeline holding and fixing device can be provided in two pieces and arranged oppositely on both sides of the pipeline 1 with the annular groove connection end, so that the force is evenly applied to the pipeline 1 with the annular groove connection end when clamping and fixing it.

[0023] Specifically, the pipe holding and fixing device includes holding and fixing vertical plates 6 that are arranged opposite to each other and extend outward respectively on the surfaces of the two pipe reinforcing holding plates 5, and the two holding and fixing vertical plates 6 that penetrate the same side of the pipe 1 with the annular groove connecting end are detachably provided with vertical plate fasteners 7. The two holding and fixing vertical plates 6 that are opposite to each other on the same side of the pipe can be fixedly connected together by the vertical plate fasteners 7 to achieve the connection and fixation between the two pipe reinforcing holding plates 5. The bottom wall of the holding and fixing vertical plates 6 is fixedly connected to the pipe holding connection plate 3, which can strengthen the fixation of the installation of the holding and fixing vertical plates 6, making it more stable and reliable during use. The vertical plate fasteners 7 are generally selected from bolts and nuts that are used in combination, which are convenient and simple to operate.

[0024] A protruding pipe holding clamping plate 8 is also provided on the inner arc surface of the pipe holding connecting plate 3 or the pipe reinforcing holding plate 5. In this embodiment, the pipe holding clamping plate 8 is arranged at the top of the pipe reinforcing holding plate 5. The pipe holding clamping plate 8 is used to clamp with the annular groove on the pipe 1 with the annular groove connecting end, and has a good anti-slip effect, which can improve the stability and firmness of the pipe 1 with the annular groove connecting end after connection.

[0025] In this embodiment, detachable connection plate fasteners 9 are evenly distributed throughout the pipe holding connection plate 3, and the connection plate fasteners 9 are arranged around the pipe 1 with the annular groove connection end. The pipe holding connection plate 3 can be connected to the flange on the pipe 2 with the flange connection end through the connection plate fasteners 9 to achieve the installation and fixation of the device. At the same time, the pipe holding clamping plate 8 and the annular groove on the pipe 1 with the annular groove connection end are clamped together to finally achieve the connection of the two pipes. The connection plate fasteners 9 are generally selected from bolts and nuts used in combination, which are convenient and simple to operate.

[0026] The description of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
