Technical Field

[0001] This utility model relates to the technical field of gas pipeline connection equipment, specifically to a quick connection clamp. Background Technology

[0002] Natural gas pipeline transportation offers advantages such as low transportation costs, small land occupation, rapid construction, large oil and gas transport capacity, high safety performance, low transportation losses, no emissions of waste gas, wastewater, and solid waste, low risk of leakage, low environmental pollution, minimal impact from severe weather, low equipment maintenance requirements, ease of management, and ease of remote centralized monitoring. However, during the laying or maintenance of natural gas pipelines, it is often necessary to repeatedly disassemble and reassemble certain pipeline connections. These connections rely on flanges, which are then secured with bolts. Therefore, repeated disassembly and reassembly are extremely laborious, and existing connection methods are not conducive to this operation. Utility Model Content

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] Example: Please refer to Figure 1-2 A quick-connect clamp includes a first clamping block 14, a second clamping block 10 hinged to the first clamping block 14, and a locking mechanism 6 mounted on the second clamping block 10 for quickly locking the first clamping block 14 and the second clamping block 10. Both the first clamping block 14 and the second clamping block 10 have inverted V-grooves 15 inside. The outer circles of two flanges 16 are in close contact with the sidewalls of the inverted V-grooves 15. The end faces of the two flanges 16 without mounting holes are in close contact under the clamping of the first clamping block 14 and the second clamping block 10. When it is necessary to disassemble or assemble pipes 7, simply align the flanges 16 on the end faces of the two pipes 7, then open the first clamping block 14 and the second clamping block 10, and then connect the aligned flanges 16. 6. Insert the flange 16 into the inverted V-groove 15 of the second clamping block 10, and then rotate the first clamping block 14 so that the other part of the aligned flange 16 is inserted into the inverted V-groove 15 of the first clamping block 14. Then, by locking the first clamping block 14 and the second clamping block 10, the aligned flange 16 will be tightly pressed against each other under the action of the inverted V-groove 15, thereby achieving the locking of the two flanges 16 and thus achieving the quick locking of the two pipes 7. When it is necessary to disassemble, simply loosen the first clamping block 14 and the second clamping block 10 to disassemble the two pipes 7. Therefore, this utility model eliminates the method of fixing the flanges 16 with bolts, making the repeated disassembly and removal of the pipes 7 easier and more convenient.

[0021] In this embodiment, a first sealing gasket 18 is provided at the top of the inverted V-groove 15, and the bottom of the first sealing gasket 18 is in close contact with the outer circular end faces of the two flanges 16, thereby effectively preventing gas in the pipeline 7 from escaping through the gap between the two flanges 16; and the end face of the flange 16 is provided with a chamfer that matches the bevel of the inverted V-groove 15, which is beneficial for the flange 16 to slide in the side wall of the inverted V-groove 15 and improves the service life of the clamp; and the interior of the first clamping block 14 and the second clamping block 10 are both provided with sealing grooves that communicate with the bottom of the inverted V-groove 15, and a second sealing gasket 17 is provided on the side wall of the sealing groove. The tight fit between ring 17 and the end face of flange 16 facilitates the guidance of flange 16 and improves the clamping seal, ensuring the clamping quality of the two pipes 7. The end faces of the first clamping block 14 and the second clamping block 10 are also provided with clamping plates 9 for clamping the pipes 7. A third sealing gasket 8 is provided between the clamping plate 9 and the pipes 7, further improving the clamping quality of the two pipes 7 and enhancing the sealing performance of the clamp. Several reinforcing ribs 13, fixed to the clamping plates 9, are provided on the side walls of the first clamping block 14 and the second clamping block 10, increasing the strength of the clamp, preventing deformation, and ensuring the clamping quality of the two flanges 16. The clamping quality is improved. First clamping plates 12 are provided on both end faces of the first clamping block 14, and second clamping plates 11, which are in close contact with the first clamping plates 12, are provided on both end faces of the second clamping block 10. One first clamping plate 12 is hinged to the adjacent second clamping plate 11, and the other first clamping plate 12 is connected to the adjacent second clamping plate 11 via a locking mechanism 6. Both the first clamping plate 12 and the second clamping plate 11 are provided with fourth sealing gaskets 19, further improving the sealing performance of the device. A groove is provided on the first clamping plate 12 near the locking mechanism 6. The locking mechanism 6 includes a component rotatably connected to the second clamping plate 11. The sleeve 3 has a rotating shaft 5, a screw 1 fixedly connected to the rotating shaft 5, and a sleeve 3 threadedly connected to the screw 1. The bottom of the sleeve 3 is provided with a base plate 4, the diameter of which is larger than the width of the groove. The screw 1 is located in the groove. The side wall of the sleeve 3 is provided with a rotating lug 2. When it is necessary to lock the first clamping block 14 and the second clamping block 10, simply rotate the rotating shaft 5 to rotate the screw 1 into the groove, and then rotate the rotating lug 2. The sleeve 3 will move downward, thereby pressing the base plate 4 against the first clamping plate 12, and then pressing the first clamping plate 12 against the second clamping plate 11, thereby locking the first clamping block 14 and the second clamping block 10.

[0022] Working principle

[0023] When it is necessary to disassemble or assemble pipe 7, simply align the flanges 16 on the end faces of the two pipes 7, then open the first clamping block 14 and the second clamping block 10, and then place the aligned flange 16 into the inverted V-groove 15 in the second clamping block 10. Then rotate the first clamping block 14 so that the other part of the aligned flange 16 is placed into the inverted V-groove 15 in the first clamping block 14. When the first clamping block 14 is close to the second clamping block 10 to the appropriate position, rotate the rotating shaft 5 to rotate the screw 1 into the inside of the groove, and then rotate the rotating lug 2. The sleeve 3 will move downward, thereby pressing the base plate 4 against the first clamping plate 12, thus clamping the first clamping plate 12 with the second clamping plate 10. The plate 11 is pressed together, thereby locking the first clamping block 14 and the second clamping block 10. During this process, the aligned flanges 16 will be pressed together by the inverted V-groove 15, thereby locking the two flanges 16 and quickly locking the two pipes 7. When disassembly is required, simply rotate the rotating ear 2 in the opposite direction, and the sleeve 3 will move upward, thereby moving the base plate 4 away from the first clamping plate 12, thereby loosening the first clamping block 14 and the second clamping block 10, and thus disassembling the two pipes 7. Therefore, this invention eliminates the method of fixing the flanges 16 with bolts, making the repeated disassembly of the pipes 7 easier and more convenient.
