Description

Technical Field

[0001] The utility model relates to the field of slip-on flanges, in particular to a slip-on flange structure which is convenient for quick installation. Background Art

[0002] A slip-on flange is a flange that is loosely fitted onto the flange of a container or pipe. The flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices. A slip-on flange is a loose flange, and the flange can be made by flanging, direct machining or welding a ring. The advantage is that when the flange is deformed, no additional torque is generated on the container or pipe. It is easy to manufacture and can be made of a material different from that of the container or pipe, which saves precious metals.

[0003] The slip-on flange is a loose flange. The flange can be made by flanging, direct machining or welding a ring. When installing, the slip-on flange is directly sleeved on the outer surface of the connecting pipe. After aligning the two connecting pipes with slip-on flanges, the slip-on flanges on the surfaces of the two connecting pipes are aligned and clamped by bolts. However, fluid is usually transported inside the pipeline, and the impact of the fluid on the pipeline will generate vibration, thereby affecting the stability of the bolt installation. There is looseness between the flanges, and the effect of clamping only by bolts is poor.

[0004] In the process of connecting two pipes, in order to smoothly transport liquid or gas after the pipes are connected, it is necessary to fix the connection between the flange and the connector. Most of the existing fixing methods use fixing bolts for fixing. If there is air leakage or liquid leakage between the two flanges, the two flanges need to be disassembled for maintenance. This method of fixing with bolts is very inconvenient to disassemble and assemble. For example, a slip-on flange structure that is easy to install quickly is disclosed in publication number CN220910773U. When the flange and the connector need to be installed, a long rod is inserted into the vertical grooves inside the flange and the connector, and the short rod is bent with the rotating rod as the center to drive the plug to be inserted into the slot for fixing. Since the material of the plug is a magnet, it is magnetically connected to the slot on the upper surface of the connector, thereby completing the connection between the flange and the connector. However, the slip-on flange structure allows the flange and the connector to be quickly disassembled through the cooperation of the internal components of the disassembly mechanism, which can save a lot of time when inspecting or repairing it. However, the biggest advantage of the slip-on flange is that it can be rotated on the surface of the connecting pipe to adjust the position of the threaded holes on the flange surface. The slip-on flange structure, which is easy to install quickly, inserts a long rod into the vertical grooves inside the flange and the connector, and moves the short rod with the rotating rod as the center to drive the plug to be inserted into the slot for fixation, resulting in the flange being unable to rotate on the flange surface, thereby changing the practicality of the slip-on flange.

[0005] Therefore, it is necessary to provide a slip-on flange structure that is easy to install quickly to solve the above technical problems. Utility Model Content

[0034] The communicating groove 10 is provided in the middle of the top of the flange 1 , a placing block 11 is fixedly installed at the bottom of the inner cavity wall of the communicating groove 10 , and a clamping groove 12 is provided in the middle of the inner cavity wall surface of the communicating groove 10 .

[0035] The fixing rod 81 is fixedly installed inside the opening hole 7 , the limiting block 83 is fixedly installed on one end of the fixing rod 81 , and the first spring 82 is sleeved on the outer surface of the fixing rod 81 .

[0036] The moving block 91 is sleeved on one side of the outer surface of the fixing rod 81 , the connecting hole 92 is opened in the middle of one side of the moving block 91 , the limiting cavity 93 is opened in the middle of the moving block 91 , and the clamping block 94 is fixedly installed on the other side of the moving block 91 .

[0037] Threaded holes 4 are provided around the top of the flange 1 , and a screw 5 is engaged with the internal threads of the threaded holes 4 . An adjusting block 6 is fixedly mounted on one end of the screw 5 .

[0038] One end of the first spring 82 is fixedly connected to the inside of the opening 7 , and the other end of the first spring 82 is fixedly connected to the surface of the moving block 91 .

[0042] When the flange 1 needs to be rotated, the user rotates the flange 1.
