Description

Technical Field

[0001] The utility model relates to the technical field related to gas installation, in particular to a butt-jointed pipe for gas installation with good sealing effect. Background Art

[0002] A gas installation butt joint with good sealing performance is a pipe component specially designed for use in gas transmission systems. Its main function is to connect two pipe sections and ensure that the joint has excellent sealing performance to prevent gas leakage. Such pipes are usually made of high-strength and corrosion-resistant materials such as stainless steel, galvanized steel or high-density polyethylene (HDPE), which can withstand the pressure and chemical properties of gas.

[0003] After searching, the Chinese patent with the publication number CN221443628U discloses a gas pipeline connector with good sealing effect. The patent records the technical solution of achieving internal sealing by providing an arc block, a first sealing gasket, and a second sealing gasket.

[0004] In this solution, although a good sealing effect is achieved when the pipes are connected, the two pipes are installed by means of bolts and hoops. It is time-consuming and labor-intensive to screw multiple bolts during installation, and there is no positioning component, which makes docking more troublesome. At the same time, the bolts may be damaged due to long-term rotation, resulting in an unstable installation. In order to solve this technical problem, the utility model proposes a docking pipe for gas installation with a good sealing effect. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] Embodiment 1: A gas installation butt-joint pipe with good sealing effect, comprising a connecting pipe 4, a first gas pipe 1 being provided at the left end of the connecting pipe 4, a second gas pipe 2 being provided at the right end of the connecting pipe 4, a limit ring 3 being fixedly connected to the outer wall of one end of the first gas pipe 1 and the second gas pipe 2, a fixed base 5 being fixedly connected to the outer wall of the connecting pipe 4, a rotating column 7 being rotatably connected to the interior of the fixed base 5, a connecting plate 6 being fixedly connected to the outer wall of the rotating column 7, a pair of fixing plates 9 being fixedly connected to the top of the connecting plate 6, a threaded rod 11 being rotatably connected between the fixing plates 9 on both sides, a connecting rod 12 being threadedly connected to the outer wall of the threaded rod 11, and a clamping block 14 being fixedly connected to the bottom end of the connecting rod 12, 14 corresponds to the limiting ring 3, and the block 14 is inserted in the limiting ring 3. At the same time, the first gas pipeline 1 and the second gas pipeline 2 are both inserted in the connecting pipe 4. A pair of positioning rods 8 are fixedly connected between the fixing plates 9 on both sides. At the same time, a pair of sliders 13 are fixedly connected on both sides of the top of the connecting rod 12, and the sliders 13 correspond to the positioning rods 8. The sliders 13 are slidably connected to the outer wall of the slider 13. A turning handle 10 is provided at one end of the threaded rod 11. A slide groove 16 is opened inside the connecting plate 6, and the slide groove 16 corresponds to the connecting rod 12. At the same time, the connecting rod 12 is slidably connected in the slide groove 16. A spring 15 is fixedly connected to the bottom of the connecting plate 6, and the other end of the spring 15 is fixedly connected to the inner wall of the fixed base 5.

[0025] After aligning the limiting rings 3 of the first gas pipeline 1 and the second gas pipeline 2 with the connecting pipeline 4, rotate the connecting plates 6 at both ends and align the block 14 at the bottom end of the connecting rod 12 with the limiting ring 3. Then, turn the handle 10 to drive the threaded rod 11 to rotate. The rotation of the threaded rod 11 drives the connecting rod 12 to move back and forth, and eventually moves the block 14 at the bottom end into the limiting ring 3, thereby fixing the first gas pipeline 1 and the second gas pipeline 2. When moving, the connecting rod 12 will maintain its position on the outer wall of the positioning rod 8 through the slider 13. At the same time, the slide groove 16 limits its movement direction, ensuring that the connecting rod 12 maintains a stable direction during movement. The connecting plate 6 is limited on the fixed base 5 by the rotating column 7, and the resilience of the spring 15 automatically resets the connecting plate 6. Through the coordinated cooperation of these components, the two pipelines can be quickly installed, significantly improving the installation efficiency.

[0026] Example 2: The difference between this example and Example 1 is that a plurality of positioning columns 18 are fixedly connected to the inner wall of the limiting ring 3, a plurality of slots 19 are opened on both sides of the connecting pipe 4, and the slots 19 correspond to the positioning columns 18, and the positioning columns 18 are inserted into the slots 19. A sealing gasket 17 is provided inside the connecting pipe 4, and the inner walls of the openings at both ends of the sealing gasket 17 are arranged in an arc shape, and the two ends of the sealing gasket 17 correspond to the first gas pipe 1 and the second gas pipe 2 respectively.

[0027] After inserting the positioning pin 18 on the retaining ring 3 into the slot 19 to initially position the pipes, continue rotating the threaded rod 11. The rotation of the threaded rod 11 pushes the connecting rod 12, gradually moving the first gas pipe 1 and the second gas pipe 2 into the connecting pipe 4. During this process, the first and second gas pipes 1 and 2 gradually penetrate deeper into the sealing gasket 17, causing the inner wall of the sealing gasket 17 to fit tightly against the outer walls of the two pipes. This fit effectively prevents gas leakage and improves overall sealing performance.

[0028] Working principle: when the staff needs to connect the first gas pipeline 1 with the second gas pipeline 2, the connecting pipe 4 will be used for connection. At this time, the limiting rings 3 on the first gas pipeline 1 and the second gas pipeline 2 are aligned with the connecting pipe 4 respectively. At this time, the positioning column 18 on the limiting ring 3 is inserted into the slot 19 to achieve positioning. At this time, one end of the first gas pipeline 1 and the second gas pipeline 2 is just inserted into the openings at both ends of the positioning column 18. At this time, the connecting plates 6 at both ends are rotated to align the block 14 at the bottom end of the connecting rod 12 with the limiting ring 3 respectively. At this time, the turning handle 10 is turned, and the threaded rod 11 is driven to rotate under the action of the turning handle 10. The rotation of the threaded rod 11 will drive the connecting rod 12 to move back and forth, thereby driving the block 14 at the bottom to move into the limiting ring 3, and the first gas pipeline 1 and the second gas pipeline 2 are connected. When the connecting rod 12 moves, it will be limited on the outer wall of the positioning rod 8 by the slider 13, and then cooperate with the slide groove 16 to limit it, so as to ensure that the connecting rod 12 maintains the same direction when moving. At the same time, the connecting plate 6 is limited on the fixed base 5 by the rotating column 7, and the connecting plate 6 is reset by the resilience of the spring 15. Through the cooperation between them, the effect of rapid installation of the two pipelines is achieved, which greatly improves the installation speed. At this time, continue to rotate the threaded rod 11, and the first gas pipeline 1 and the second gas pipeline 2 will be driven by the connecting rod 12 to continue to move into the connecting pipeline 4. At this time, the first gas pipeline 1 and the second gas pipeline 2 will gradually extend into the sealing gasket 17, thereby prompting the inner wall of the sealing gasket 17 to fit closely with the outer wall of the first gas pipeline 1 and the second gas pipeline 2, thereby preventing gas leakage and improving the sealing.
