Description

Technical Field

[0001] The utility model relates to the technical field of two-way pipes, and specifically relates to a hot-forged two-way pipe fitting. Background Technique

[0002] In the field of hot-forged pipe fittings, two-way pipe fittings, as common connecting components in pipeline systems, are widely used in various industrial occasions, such as industries like petroleum, chemical industry, metallurgy, and energy. Among them, the T-shaped two-way pipe, due to its unique structural characteristics (including a long arm and a cross arm, with the middle of the cross arm perpendicularly fixed to and communicating with the long arm), can achieve the branching or merging of fluid flow directions, and thus plays an important role in fluid transmission systems;

[0003] However, when connecting the T-shaped two-way pipe to a pipeline, one of the common connection methods is to use flanges and multiple bolts for fastening. When one or more of the multiple fastening bolts rust due to reasons such as a humid environment or medium corrosion, the difficulty of disassembly will increase significantly. The rusty bolts are not only difficult to loosen with conventional tools but may also break or be damaged due to excessive force, thereby affecting the integrity and stability of the entire connection structure. This not only increases the difficulty and cost of maintenance work but may also lead to more serious consequences due to delayed maintenance. Therefore, we propose a hot-forged two-way pipe fitting to solve the above problems. Content of the Utility Model

[0025] Embodiment

[0026] As Figures 1-5As shown in the figure, a hot forging two-way pipe fitting proposed by an embodiment of the present utility model includes a two-way pipe main body 1. The bottom of the two-way pipe main body 1 is communicated and fixed with a lower through pipe 18. First sealing rings 2 are fixedly connected to both ends of the two-way pipe main body 1 and the bottom end of the lower through pipe 18. Two cavities 3 are opened on the first sealing ring 2. Moving rings 4 are provided on both ends of the two-way pipe main body 1 and the lower through pipe 18. Two flexible steel ropes 5 are fixedly connected to one side of the moving ring 4. A fixed pulley 6 is rotatably connected to the inner wall of one side of the cavity 3. The end of the flexible steel rope 5 bypasses one side of the corresponding fixed pulley 6 and is fixedly connected to a connecting block 7. A fixing rod 8 is welded to the inner wall of one side of the cavity 3. A latch 9 is slidably connected to the fixing rod 8. A first spring 10 is fixedly connected between the end of the latch 9 and the inner wall of one side of the corresponding cavity 3. One side of the connecting block 7 is fixedly connected to one side of the corresponding latch 9. A second sealing ring 12 is in movable contact with one side of the first sealing ring 2. A pipe 11 is communicated and fixed to one side of the second sealing ring 12. Two mounting blocks 13 are fixedly connected to the other side of the second sealing ring 12. A clamping groove 14 is opened on the mounting block 13. The clamping groove 14 is clamped with the corresponding latch 9. Move the moving ring 4. The moving ring 4 slides on the corresponding T-shaped rod 16 and compresses the second spring 17. The moving ring 4 drives the corresponding connecting block 7 to move through the flexible steel rope 5. The connecting block 7 drives the corresponding latch 9 to slide on the fixing rod 8. The latch 9 compresses the corresponding first spring 10 during the movement. Then, the mounting block 13 on the second sealing ring 12 is inserted into the corresponding cavity 3 through the rectangular hole 15. When one side of the first sealing ring 2 contacts one side of the corresponding second sealing ring 12, at this time, release the force on the moving ring 4. The first spring 10 in the compressed state resets. Under the action of the self-elastic force of the first spring 10, the first spring 10 drives the corresponding latch 9 to be clamped with the clamping groove 14, so as to connect the pipe 11 with the two-way pipe fitting. During disassembly and assembly, just move the moving ring 4, so the operation is simple and convenient during the disassembly and assembly process. At the same time, through the setting of the first sealing ring 2 and the second sealing ring 12, the sealing performance after connection is improved.

[0027] In some embodiments, the first spring 10 is movably sleeved on the corresponding fixing rod 8. The setting of the first spring 10 plays a role in resetting.

[0028] In some embodiments, two T-shaped rods 16 are fixedly connected to the other side of the first sealing ring 2. The T-shaped rods 16 are slidably connected to the corresponding moving rings 4.

[0029] In some embodiments, a second spring 17 is fixedly connected between the inner wall of one side of the T-shaped rod 16 and the other side of the corresponding moving ring 4. The second spring 17 is movably sleeved on the corresponding T-shaped rod 16.

[0030] In some embodiments, a rectangular hole 15 is formed in the inner wall on the other side of the cavity 3. The inner wall of the rectangular hole 15 is in movable contact with the outer side of the corresponding mounting block 13. The setting of the mounting block 13 plays a connecting role.

[0031] In some embodiments, two guiding holes are formed in the moving ring 4. The moving ring 4 is slidably connected with the corresponding T-shaped rod 16 through the guiding holes. The setting of the T-shaped rod 16 plays a limiting role.

[0032] In some embodiments, a flow guiding block 19 is fixedly connected to the inner wall of the top of the two-way pipe body 1. The flow guiding block 19 is triangular, and arc-shaped portions 20 are provided on both sides of the flow guiding block 19.

[0033] During the working principle or structural principle, during use and installation, move the moving ring 4. The moving ring 4 slides on the corresponding T-shaped rod 16 and compresses the second spring 17. The moving ring 4 drives the corresponding connecting block 7 to move through the flexible steel cable 5. The connecting block 7 drives the corresponding latch 9 to slide on the fixed rod 8. The latch 9 compresses the corresponding first spring 10 during the movement. Then, insert the mounting block 13 on the second sealing ring 12 into the corresponding cavity 3 through the rectangular hole 15. When the first sealing ring 2 contacts one side of the corresponding second sealing ring 12, at this time, release the force on the moving ring 4. The first spring 10 in the compressed state resets. Under the action of the self-elastic force of the first spring 10, the first spring 10 drives the corresponding latch 9 to be engaged with the card slot 14, so as to connect the pipeline 11 with the two-way pipe fitting. During disassembly and assembly, just move the moving ring 4, so the operation is simple and convenient during the disassembly and assembly process. At the same time, through the settings of the first sealing ring 2 and the second sealing ring 12, the sealing performance after connection is improved. When the liquid enters the lower through pipe 18 from the two-way pipe body 1, the bottom end of the flow guiding block 19 can divide the liquid entering the two-way pipe body 1, and then under the action of the arc-shaped portions 20 on both sides of the flow guiding block 19, the liquid is guided smoothly, avoiding the liquid entering the two-way pipe body 1 from directly hitting the inner wall of the lower through pipe 18, so as to protect the T-shaped two-way pipe.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
