In the absence of further restrictions, an element defined by the statement "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.
[0037] At present, in the installation of pressure pipelines, most of the pipe elbow structures are installed with fixed brackets on both sides of the elbow. Specifically, the pipe elbow structure generally includes an elbow, a first pipe and a second pipe. The elbow is connected between the first pipe and the second pipe. Fixed brackets are installed on the first pipe and the second pipe to achieve fixed connection between the first pipe and the elbow, and between the second pipe and the elbow. However, since the fixing method of the fixed bracket is rigid fixing, in the specific implementation process, steel fixed brackets are generally installed within 300mm on both sides of the elbow structure.
[0038] After the pipeline system is in operation, problems such as gas collection and surge are likely to occur at the elbow structure due to the excessively high flow rate of the medium in the pipeline, which will form shear force on the pipeline elbow structure, causing the pipeline to burst, crack and fall off, increase the workload of operation and maintenance, and affect the normal use of the pipeline system.
[0039] To solve the above technical problems, please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of a pipeline elbow buffer device 100 provided in some embodiments of the present application; Figure 2 for Figure 1 The present application provides a pipeline elbow buffer device 100 , which may include a first fixing bracket 110 , a second fixing bracket 120 and a buffer assembly 130 .
[0040] Specifically, the first fixing bracket 110 and the second fixing bracket 120 are formed as clamps, and the connection between the first pipeline 300, the elbow 200 and the second pipeline 400 is realized by the clamp connection. The first fixing bracket 110 is clamped on the circumferential outer side of the first pipeline 300, and the second fixing bracket 120 is clamped on the circumferential outer side of the second pipeline 400.
[0041] The buffer assembly 130 is located on the outside of the elbow 200. The buffer assembly 130 may include a connecting plate 131 and an elastic member 132. One end of the connecting plate 131 is connected to the first fixed bracket 110, and the other end is connected to the second fixed bracket 120. The elastic member 132 may include a first end 1321 and a second end 1322. The first end 1321 abuts against the connecting plate 131, and the second end 1322 abuts against the elbow 200.
[0042] In this way, when the elbow 200 is out of service due to excessively high flow velocity in the pipeline or severe gas accumulation in the pipe, a buffer component 130 is provided on the outside of the elbow 200. When the elbow structure vibrates, the buffer component 130 will undergo elastic deformation. The elastic member 132 in the buffer component 130 can absorb energy and convert the shear force exerted on the elbow 200 into elastic potential energy, thereby ensuring the stability of the elbow 200 structure and preventing the pipeline from bursting, cracking and falling off.
[0043] The elastic member 132 may be a spring.
[0044] In some embodiments of the present application, the number of elastic members 132 may be multiple. In a specific implementation, the number of elastic members 132 may be two, three, or four. By providing multiple elastic members 132, the energy absorption capacity of the elastic members 132 may be adjusted to achieve energy absorption effects for elbow 200 structures of different sizes and energy absorption requirements, thereby expanding the overall scope of application of the device.
[0045] In some embodiments of the present application, the first end 1321 of the elastic member 132 is detachably connected to the connecting plate 131. Thus, through the detachable connection between the first end 1321 and the connecting plate 131, the elastic member 132 with a different elastic coefficient can be replaced so that the pipe elbow buffer device 100 can meet the energy absorption requirements of elbow 200 structures of different specifications.
[0046] Specifically, the first end 1321 of the elastic member 132 can be clamped with the connecting plate 131, a first clamping structure is provided on the first end 1321, and a second clamping structure is provided on the connecting plate 131. The first clamping structure and the second clamping structure are clamped to achieve the clamping between the elastic member 132 and the connecting plate 131.
[0047] In some embodiments of this application, please continue to refer to Figure 2 The buffer assembly 130 may further include an abutment plate 133, which is sandwiched between the second end 1322 of the elastic member 132 and the elbow 200. Thus, the abutment plate 133 is provided to increase the abutment area between the elastic member 132 and the elbow 200, thereby increasing the stability of the abutment between the elastic member 132 and the elbow 200.
[0048] In some embodiments of this application, please continue to refer to Figure 2 The abutment plate 133 includes an abutment surface facing the elbow 200, and the abutment surface can be formed as a curved surface matching the elbow 200, so that the abutment plate 133 can fit with the elbow 200, thereby increasing the abutment area between the elastic member 132 and the elbow 200, and ensuring the stability of the abutment between the elastic member 132 and the elbow 200.
[0049] In some embodiments of this application, please continue to refer to Figure 2 An elastic gasket 1331 is provided on the abutting surface. Specifically, the elastic gasket 1331 can be a plastic part, a rubber part, etc. When the abutting plate 133 abuts against the elbow 200, the elastic gasket 1331 is deformed so that the abutting plate 133 can fit the elbow 200, thereby increasing the abutting area between the elastic member 132 and the elbow 200, thereby ensuring the stability of the abutment between the elastic member 132 and the elbow 200.
[0050] In some embodiments of this application, please continue to refer to Figure 2 A contact protrusion 1332 may also be provided on the surface of the elastic gasket 1331 on the side facing the elbow 200. The contact protrusion 1332 is provided to increase the friction between the contact plate 133 and the elbow 200 to prevent the contact plate 133 from being separated from the elbow 200 during the vibration of the elbow 200, thereby further ensuring the stability of the contact between the elastic member 132 and the elbow 200.
[0051] Specifically, the abutting protrusions 1332 can be a plurality of spherical protrusions, a plurality of cylindrical protrusions, special-shaped protrusions, etc.
[0052] In some embodiments of the present application, the pipe elbow buffer device 100 may further include a first connecting rod 140, one end of which is connected to the connecting plate 131, and the other end of which is connected to the first fixing bracket 110. Thus, the connection between the connecting plate 131 and the first fixing bracket 110 is achieved by providing the first connecting rod 140.
[0053] Specifically, the first connecting rod 140 is formed as a telescopic rod. By setting the first connecting rod 140 as a telescopic rod, the pipe elbow buffer device 100 can meet the distance between the connecting plate 131 and the first fixed bracket 110 required by elbows 200 of different specifications, thereby improving the application range of the pipe elbow buffer device 100.
[0054] In some embodiments of the present application, the pipeline elbow buffer device 100 may further include a second connecting rod 150, one end of which is connected to the connecting plate 131, and the other end of which is connected to the second fixing bracket 120. Thus, the connection between the connecting plate 131 and the second fixing bracket 120 is achieved by providing the second connecting rod 150.
[0055] Specifically, the second connecting rod 150 is formed as a telescopic rod. By setting the second connecting rod 150 as a telescopic rod, the pipe elbow buffer device 100 can meet the distance between the connecting plate 131 and the second fixed bracket 120 required by elbows 200 of different specifications, thereby improving the application range of the pipe elbow buffer device 100.
[0056] The above description is only a specific embodiment of the present invention, so that those skilled in the art can understand or implement the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments described herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
