Description

Technical Field

[0001] This utility model relates to the field of four-way pipe fittings, and in particular to a rigid connection grooved four-way pipe fitting with high sealing performance. Background Technology

[0002] Grooved four-way fittings are key components in piping systems used to connect main pipes and branch pipes. Their main function is to allow the medium to flow from the main pipe to the branch pipe or from the branch pipe to the main pipe during fluid transportation, thereby creating a flexible pipe network layout. Through the grooved connection structure, pipes and fittings can be quickly assembled. This connection method is characterized by convenient installation and high construction efficiency, and can effectively ensure the connectivity of the piping system.

[0003] High-sealing rigid connection grooved four-way fittings are products that optimize and upgrade the sealing performance and connection strength based on traditional grooved four-way fittings. The core of these fittings lies in the structural design and material selection, which creates a tight sealing interface between the fitting and the pipeline. At the same time, it ensures that the connection part has strong rigidity and can withstand the pressure fluctuations and vibrations of the pipeline system during operation, avoiding leakage or loosening of the connection. This ensures the stable and safe operation of the pipeline system in complex working environments with high sealing requirements.

[0004] In practical applications, existing grooved four-way fittings use rubber sealing rings installed in the grooves. The compression deformation of the sealing rings when the gland bolts are tightened fills the gap between the fitting and the pipe, thus preventing fluid leakage from the connection. However, due to the aging and elasticity decay of the rubber sealing rings under long-term pressure and temperature changes, when the pipeline system is subjected to large vibrations or impact loads, slight displacement will occur between the gland and the fitting, resulting in uneven stress on the sealing rings and a decrease in sealing effect. Summary of the Invention

[0005] The purpose of this utility model is to provide a rigid connection grooved four-way pipe fitting with high sealing performance, which solves the problem that rubber sealing rings will age after long-term use, resulting in uneven stress on the sealing rings and thus a decrease in sealing effect.

[0006] To achieve the above objectives, this utility model provides a high-sealing rigid connection grooved four-way pipe fitting, including a four-way connecting pipe. Connecting rings are fixedly connected to all four sides of the four-way connecting pipe. A sealing mechanism is provided on one side of each of the connecting rings. Supporting mechanisms are provided on both the left and right sides of the four-way connecting pipe. The supporting mechanisms support the four-way connecting pipe.

[0025] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a high-sealing rigid connection grooved four-way pipe fitting, including a four-way connecting pipe 1, which serves as the main body to achieve pipe connection in four directions. Connecting rings 2 are fixedly connected to all four sides of the four-way connecting pipe 1 to position the pipe and provide an installation base for the sealing mechanism 3. A sealing mechanism 3 is provided on one side of each of the multiple connecting rings 2 to achieve a high sealing effect at the connection. Supporting mechanisms 4 are provided on both the left and right sides of the four-way connecting pipe 1 to support the four-way connecting pipe 1 and ensure its stability. The sealing mechanism 3 includes multiple sealing rings 301, whose outer sides are fixed to the inner side of the connecting rings 2 to form an initial sealing surface. The outer sides of the multiple sealing rings 301 are fixedly connected to the connecting rings 2. Inside ring 1 2, the position of the fixed sealing ring 301 is fixed. Each of the multiple sealing rings 301 has a sealing groove 302 on one side, which fits against the outer wall of the pipe to form an initial sealing surface. Each of the multiple connecting rings 1 2 has a connecting ring 2 303 slidably connected to its outer wall, sliding along the connecting ring 1 2 to drive the sealing insert ring 304 into the sealing groove 302. Each of the multiple connecting ring 2 303 has a sealing insert ring 304 fixedly connected to its inner side, inserting into the sealing groove 302 to enhance the sealing effect. Each of the multiple connecting rings 1 2 has a fixed ring 305 fixedly connected to one side of its outer wall, providing an installation position for the sliding groove 306 and the locking assembly 312. Each of the multiple fixed rings 305 has multiple sliding grooves 306 on one side, which can cooperate with the sliding block 308 to allow the connecting ring 2 303 to slide along the connecting ring 1 2. 2. Sliding: One side of each of the multiple sliding grooves 306 is connected to a slot 307, which cooperates with the locking block 311 to achieve the initial positioning of the second connecting ring 303. One side of each of the multiple second connecting rings 303 is fixedly connected to multiple sliding blocks 308, which can slide within the sliding grooves 306 to drive the second connecting ring 303 to move. One side of each of the multiple sliding blocks 308 is provided with a groove 309 to accommodate the spring 310 and the locking block 311 and provide them with room to move. The interior of each of the multiple grooves 309 is fixedly connected to a spring 310, which pushes the locking block 311 into the slot 307 to achieve the initial positioning of the second connecting ring 303. The other end of each of the multiple springs 310 is fixedly connected to a locking block 311, which engages with the slot 307 to achieve the initial positioning of the second connecting ring 303 and to lock the connection ring 303. The components 312 work together to achieve a secure lock. The outer walls of the multiple fixed rings 305 are provided with locking components 312 to further lock the locking blocks 311 and prevent the connecting ring 303 from loosening. The locking components 312 include multiple fixing blocks 3121, which are fixed to the outer walls of the fixed rings 305 to provide installation positions for the locking blocks 3122 and locking bolts 3124. One side of each fixing block 3121 is fixedly connected to the outer wall of the corresponding fixed ring 305. One side of each locking block 311 has a locking groove 3123, which cooperates with the locking block 3122 to lock the locking block 311. One side of each fixing block 3121 is slidably connected to a locking block 3122, which is inserted into the locking groove 3123 to lock the locking block 311 and prevent the connecting ring 303 from loosening.One side of each of the multiple locking blocks 3122 passes through the fixing block 3121 and slides within the corresponding locking groove 3123, achieving a locking engagement between the locking blocks 3122 and the locking groove 3123. Each of the tops of the multiple fixing blocks 3121 is rotatably connected to a locking bolt 3124. Tightening the bolts locks the locking blocks 3122 to ensure they do not loosen. One end of each locking bolt 3124 passes through both the fixing block 3121 and the locking block 3122, fixing the locking block 3122 to the fixing block 3121 to securely lock the latch 311.

[0027] Specifically, in this high-sealing rigid connection grooved four-way fitting, the four-way connecting pipe 1 serves as the main body, and the connecting ring 2, which is fixedly connected around the four sides, is used to position the pipe and provide an installation base for the sealing mechanism 3. In the sealing mechanism 3, the sealing ring 301 is fixed inside the connecting ring 2, and the sealing groove 302 on one side of it fits against the outer wall of the pipe to form an initial sealing surface. The sealing insert ring 304 on the inner side of the connecting ring 303, which is slidably connected to the outer wall of the connecting ring 2, can be inserted into the sealing groove 302 to enhance the sealing effect. The sliding groove 306 on the fixed ring 305 fixed on one side of the outer wall of the connecting ring 2 and the connecting ring 303 are connected to the connecting ring 303. The sliding block 308 on the side cooperates to allow the second connecting ring 303 to slide along the first connecting ring 2. The spring 310 in the groove 309 on the sliding block 308 pushes the locking block 311 into the slot 307 to achieve the initial positioning of the second connecting ring 303. The locking block 3122 on the fixing block 3121 on the outer wall of the fixed ring 305 is inserted into the locking groove 3123 of the locking block 311, and then the locking bolt 3124 is tightened to lock it, preventing the second connecting ring 303 from loosening and ensuring that the sealing ring 304 and the sealing groove 302 are tightly fitted to ensure high sealing performance. The support mechanism 4 provides stable support for the four-way connecting pipe 1.

[0028] Reference Figure 2 , Figure 5 and Figure 6The support mechanism 4 includes two support rings 401, whose inner sides are fixed to the left and right sides of the outer wall of the four-way connecting pipe 1 to provide the mounting base for the support structure. The inner sides of the two support rings 401 are respectively fixedly connected to the left and right sides of the outer wall of the four-way connecting pipe 1 to fix the position of the support rings 401. The outer walls of the two support rings 401 are each provided with annular grooves 402, which cooperate with arc-shaped blocks 403 to realize circumferential adjustment of the support position. Arc-shaped blocks 403 are slidably connected inside the two annular grooves 402, and slide along the annular grooves 402 to adjust the support position. Hollow plates 404 are fixedly connected to the bottom of the two arc-shaped blocks 403, fixing the hollow plates 404 and transmitting the support force. The inner sides of the two hollow plates 404 are slidably connected to the bottom of the two arc-shaped blocks 403. The hollow plate 404 is dynamically connected to a movable plate 405, which moves up and down within the hollow plate 404 to adjust the support height. Support plates 406 are rotatably connected to the bottom of each movable plate 405, fitting against the support surface and rotating with the angle of the support surface to enhance support stability. Adjustment components 407 are provided on adjacent sides of each of the two support rings 401 to adjust the angle of the hollow plate 404 relative to the support rings 401, thereby changing the support direction. Limiting components 408 are provided on the opposite sides of each of the two hollow plates 404 to lock the position of the movable plates 405 and fix the support height. The adjustment components 407 include two adjusting blocks 4071, which are fixed on adjacent sides of the hollow plate 404 to provide mounting positions for adjusting bolts 4073. Two adjusting blocks 4071 are fixedly connected to adjacent sides of the hollow plate 404, fixing the position of the adjusting blocks 4071. Multiple adjusting holes 4072 are provided on adjacent sides of the two supporting rings 401, which cooperate with adjusting bolts 4073 to adjust the angle of the hollow plate 404. Adjusting bolts 4073 are rotatably connected to adjacent sides of the two adjusting blocks 4071, passing through the adjusting blocks 4071 and screwed into the adjusting holes 4072 to adjust the angle of the hollow plate 404. The far ends of the two adjusting bolts 4073 both pass through the adjusting blocks 4071 and are rotatably connected to the interior of the corresponding adjusting holes 4072. Adjustment of the support direction is achieved by screwing into different adjusting holes 4072. (Limiting component) 408 includes two limiting bolts 4081, which are rotatably connected to the hollow plate 404 on the opposite side and inserted into limiting holes 4082 to lock the moving plate 405. The adjacent ends of the two limiting bolts 4081 are rotatably connected on the opposite side of the hollow plate 404 to fix the rotation position of the limiting bolts 4081. The opposite sides of the two moving plates 405 are provided with multiple limiting holes 4082, which cooperate with the limiting bolts 4081 to limit the movement of the moving plate 405. The adjacent ends of the two limiting bolts 4081 pass through the hollow plate 404 and are rotatably connected to the interior of the corresponding limiting holes 4082. The position of the moving plate 405 is fixed by screwing into the limiting holes 4082 to lock the support height.

[0029] Specifically, in the support mechanism 4, the inner sides of two support rings 401 are fixed to the left and right sides of the outer wall of the four-way connecting pipe 1. The annular groove 402 of its outer wall cooperates with the arc-shaped block 403, allowing the arc-shaped block 403 to slide along the annular groove 402, thereby realizing the circumferential adjustment of the support position to adapt to different installation scenarios. The movable plate 405, which is slidably connected inside the hollow plate 404 fixed at the bottom of the arc-shaped block 403, can move up and down in the hollow plate 404 to adjust the support height and meet the support requirements of different heights. The support plate 406, which is rotatably connected at the bottom of the movable plate 405, can adaptively rotate with the angle of the support surface, enhancing the fit with the support surface and improving the support stability. In the adjustment component 407, the adjustment block 4071 is fixed to the adjacent side of the hollow plate 404, and the adjustment bolt 4073 passes through the adjustment block 4071 and is connected to the adjustment bolt on the adjacent side of the support ring 401. The joint hole 4072 is rotatably connected. By screwing the adjusting bolt 4073 into different adjusting holes 4072, the tilt angle of the hollow plate 404 relative to the supporting ring 401 can be changed, thereby adjusting the support direction and allowing the support force to act on the four-way connecting pipe 1 in different directions. In the limiting assembly 408, the limiting bolt 4081 is rotatably connected to the side of the hollow plate 404 away from it. Its adjacent end passes through the hollow plate 404 and is rotatably connected to the limiting hole 4082 on the side of the moving plate 405 away from it. When the moving plate 405 is adjusted to a suitable height, the limiting bolt 4081 is screwed into the corresponding limiting hole 4082 to lock the position of the moving plate 405 and prevent it from sliding up and down during the support process, ensuring the stability of the support height. This allows the support mechanism 4 to achieve stable support for the four-way connecting pipe 1 and adjust the support position, height, and direction.

[0030] Reference Figure 3 , Figure 4 and Figure 6 Multiple sliding blocks 308 have limit grooves 6 on their front and rear sides to provide sliding tracks for limit blocks 5 and restrict the movement direction of the locking blocks 311. The front and rear sides of multiple locking blocks 311 are fixedly connected to limit blocks 5 and slide within the limit grooves 6 to prevent the locking blocks 311 from shifting or rotating. The front and rear sides of two hollow plates 404 are provided with sliding grooves 8, which cooperate with sliders 7 to guide the moving plate 405 to move smoothly. The top of the front and rear sides of the two moving plates 405 are fixedly connected to sliders 7, which slide within the sliding grooves 8 to prevent the moving plate 405 from shaking or tilting. Multiple sealing rings 304 are slidably connected to the interior of the corresponding sealing grooves 302 and smoothly inserted into the sealing grooves 302 to form a sealing surface. The size of the sealing rings 304 and the sealing grooves 302 are matched to ensure fitting accuracy and achieve a high sealing effect.

[0031] Specifically, when the locking block 311 extends and retracts within the groove 309 under the action of the spring 310, the limiting block 5 slides within the limiting groove 6, which restricts the movement direction of the locking block 311 and prevents it from shifting or rotating during the extension and retraction process. When the moving plate 405 moves up and down within the hollow plate 404 to adjust the support height, the slider 7 slides within the sliding groove 8, which guides the moving plate 405 to move smoothly in the vertical direction, preventing the moving plate 405 from shaking or tilting during the movement. When the connecting ring 2 303 slides along the connecting ring 1 2, the sealing ring 304 can smoothly slide into the sealing groove 302, and the two fit tightly together to form a sealing surface, effectively preventing fluid leakage from the connection and achieving high sealing performance.

[0032] Working principle: When using this high-sealing rigid grooved four-way fitting, the connecting ring 2 around the four-way connecting pipe 1 is used for initial positioning of the pipe. The sealing ring 301 is fixed inside the connecting ring 2, and the sealing groove 302 on one side can fit against the outer wall of the pipe to form an initial sealing surface. When the connecting ring 303 slides along the outer wall of the connecting ring 2, the inner sealing ring 304 will be inserted into the sealing groove 302 to further enhance the sealing effect. During the sliding process, the sliding block 308 on one side of the connecting ring 303 moves in the sliding groove 306 on the fixed ring 305. When the sliding block 308 reaches the locking position... When the ring is in position 307, the spring 310 in the groove 309 will push the locking block 311 into the groove 307, achieving the initial positioning of the connecting ring 2 303. At this time, the locking block 3122 on the fixing block 3121 on the outer wall of the fixing ring 305 can be slidably inserted into the locking groove 3123 of the locking block 311. Then, by rotating the locking bolt 3124, it will pass through the fixing block 3121 and the locking block 3122 in sequence and be tightened, thereby firmly locking the locking block 311, preventing the connecting ring 2 303 from loosening, and ensuring that the sealing ring 304 and the sealing groove 302 are always tightly fitted to maintain good sealing performance.

[0033] Furthermore, when the support mechanism 4 is working, the inner sides of the two support rings 401 are fixed to the left and right sides of the outer wall of the four-way connecting pipe 1, providing an installation base for the entire support structure. The annular groove 402 on its outer wall allows the arc-shaped block 403 to slide along the annular groove 402, thereby adjusting the support position to adapt to different installation environments. The movable plate 405, which is slidably connected inside the hollow plate 404 at the bottom of the arc-shaped block 403, can move up and down in the hollow plate 404 to adjust the support height. The support plate 406, which is rotatably connected to the bottom of the movable plate 405, can fit against the ground or support surface to enhance the support stability. In the adjustment assembly 407, the adjustment block 4071 is fixed to the adjacent side of the hollow plate 404. Rotating the adjustment bolt 4073 allows it to pass through the adjustment block 4071 and the adjustment hole 407 on the adjacent side of the support ring 401. 2. Rotary connection: By screwing the adjusting bolt 4073 into different adjusting holes 4072, the relative angle between the hollow plate 404 and the supporting ring 401 can be changed, thereby adjusting the support direction. In the limiting assembly 408, the limiting bolt 4081 is rotatably connected to the side of the hollow plate 404 away from it. Rotating the limiting bolt 4081 allows it to pass through the hollow plate 404 and be rotatably connected to the limiting hole 4082 on the side of the moving plate 405 away from it. When the moving plate 405 is adjusted to a suitable height within the hollow plate 404, the limiting bolt 4081 is screwed into the corresponding limiting hole 4082, which can limit the sliding of the moving plate 405, ensuring that the support height is fixed, thereby achieving stable support for the four-way connecting pipe 1 and adjusting the support position, height, and direction, ensuring that the pipe remains stable during operation.

Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
