Description

Technical Field

[0001] The utility model relates to the technical field of pipe fittings, in particular to a high-strength pipe fitting with a buffer structure. Background Art

[0002] Pipe fittings are a general term for components in pipeline systems that play roles in connection, control, direction change, diversion, sealing, and support. When the direction of the fluid needs to be changed at the confluence of some pipelines, bent pipes are needed to guide the water flow. In this process, the long-term flowing water will impact the bends of the bent pipes, causing the pipes at the bends to easily rupture, affecting the overall service life of the pipe fittings. Therefore, a buffer structure is generally set at the bends for protection.

[0003] After searching, Chinese patent announcement number: CN219102342U discloses a pipe fitting with a buffering function, including buffering the water flow velocity inside the L-shaped pipe fitting by arranging a water flow buffering mechanism inside the water inlet pipe of the L-shaped pipe fitting. The arc-shaped protective block in the buffering protective block can play a certain protective role on the inner wall of the pipe fitting at the bend. At the same time, the first buffer layer and the second buffer layer arranged on the outside of the arc-shaped protective block can buffer the impact force of the water flow to a certain extent.

[0004] In actual use of the above-mentioned pipe fittings, the arc-shaped protection blocks and buffer layers are generally made of flexible rubber materials. During long-term impact, the buffer mechanism is easily compressed for a long time, which may cause the deformation of the arc-shaped protection blocks to be unable to recover, thereby affecting the buffer protection effect. Since the arc-shaped protection blocks are directly fixedly connected to the inside of the pipe fittings, it is difficult to directly disassemble them. At this time, the entire pipe fitting needs to be replaced and repaired, which increases the maintenance cost. Therefore, a high-strength pipe fitting with a buffer structure is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 The utility model provides an embodiment: a high-strength pipe fitting with a buffer structure, including a bending pipe 1, the upper end of the bending pipe 1 is fixedly connected with a feed pipe 2, and the right end of the bending pipe 1 is fixedly connected with a discharge pipe 3. The object to be transported can enter the pipe fitting through the feed pipe 2, and after being guided and turned at the bending pipe 1, it is discharged through the discharge pipe 3. It is suitable for the corners of the pipeline.

[0032] Reference Figure 2-Figure 4 The bottom end of the bending tube 1 is fixedly connected with a threaded tube 4, the interior of the threaded tube 4 is interconnected with the interior of the bending tube 1, the upper end of the interior of the threaded tube 4 is fixedly connected with a limiting ring 5, the internal thread of the threaded tube 4 is connected with a threaded plate 6, and the threaded plate 6 can perform linear movement in the up and down directions relative to the threaded tube 4 when rotating, the upper surface of the threaded plate 6 and the bottom surface of the limiting ring 5 fit each other, and the limiting ring 5 can limit the movement of the threaded plate 6 to prevent the threaded plate 6 from moving too much upward to enter the interior of the bending tube 1, and when the threaded plate 6 moves to the limiting ring 5, it cannot Move again, an installation unit is provided at the bottom of the threaded plate 6, and the installation unit includes a fixed cylinder 61, which is fixedly connected to the bottom surface of the threaded plate 6, and the threaded plate 6 will move synchronously with the fixed cylinder 61. A rotating ring plate 62 is fixedly connected to the bottom end of the fixed cylinder 61, and when the rotating ring plate 62 rotates, the fixed cylinder 61 can be driven to move synchronously. The outer wall of the rotating ring plate 62 is provided with anti-slip grooves. When the staff twists the rotating ring plate 62, the threaded plate 6 can be driven to rotate through the fixed cylinder 61, so that the threaded plate 6 can be installed and disassembled inside the threaded cylinder 4.

[0033] A protective plate 7 is provided above the threaded plate 6. The diameter of the protective plate 7 is smaller than the internal diameter of the limiting ring 5. The protective plate 7 can enter into the bending tube 1 through the threaded tube 4. A limiting unit is provided at the bottom of the protective plate 7. The limiting unit includes a screw 71. The pitch of the thread arranged on the outer side of the screw 71 is the same as the pitch of the threaded tube 4. The rotation of the screw 71 is connected to the bottom surface of the protective plate 7. The bottom end of the screw 71 passes through the threaded plate 6. The bottom end of the screw 71 is fixedly connected with a handle 72. The staff can drive the screw 71 to rotate by twisting the handle 72, so that the screw 71 drives the protective plate 7 to move linearly in the up and down directions relative to the threaded plate 6.

[0034] A protective rubber ring 8 is fixedly connected to the outer side of the protective plate 7. The protective rubber ring 8 can be bent and deformed. The bottom surface of the protective rubber ring 8 fits with the inner wall surface of the bending tube 1. The protective rubber ring 8 can seal and protect the gap between the protective plate 7 and the bending tube 1. A sealing rubber sleeve 9 is fixedly connected to the bottom of the threaded plate 6. The bottom surface of the sealing rubber sleeve 9 fits with the upper surface of the limiting ring 5. The sealing rubber sleeve 9 can seal the limiting ring 5 to avoid water leakage.

[0035] When the protective plate 7 is inserted into the interior of the bending tube 1 through the threaded tube 4, the protective rubber ring 8 and the sealing rubber sleeve 9 can be deformed accordingly without hindering the movement of the protective plate 7. After the staff inserts the protective plate 7 into the interior of the bending tube 1, the staff can twist the rotating ring plate 62 to drive the threaded plate 6 to rotate and enter the threaded tube 4. While twisting the rotating ring plate 62, grasp the handle 72 to prevent the movement of the threaded plate 6 from affecting the position of the protective plate 7. The thread on the outside of the screw 71 is opposite to the thread on the threaded plate 6. When the threaded plate 6 is rotated to fit with the bottom surface of the limit ring 5, the screw 71 can be rotated to drive the protective plate 7 to move downward, thereby driving the protective rubber ring 8 and the sealing rubber sleeve 9 to move downward to fit the inner wall of the bending tube 1 and the upper surface of the limit ring 5 respectively, thereby The bottom of the protective plate 7 is sealed to avoid water leakage. At this time, when water flows into the bending tube 1, the protective plate 7 can protect the bending part of the bending tube 1 to avoid the water flow directly impacting the bending part of the bending tube 1, which affects the overall service life of the pipe fitting. When the protective plate 7 is worn after being used for a period of time, the rotating ring plate 62 and the handle 72 can be screwed to drive the protective plate 7 to move downward and leave the bending tube 1 for direct replacement. The operation is simple. The fixed connections of the pipe fitting are all fixed with bolts and can be directly disassembled and replaced to reduce costs. When the protective plate 7 leaves the bending tube 1, the protective rubber ring 8 and the sealing rubber sleeve 9 can be bent and deformed accordingly to avoid obstacles to the removal of the protective plate 7.

[0036] Reference Figure 2A cylinder 10 is arranged inside the feed pipe 2, and a spiral auger 11 is fixedly connected to the outside of the cylinder 10. The outer wall of the spiral auger 11 is fixedly connected to the inner wall of the feed pipe 2. When the water flows through the feed pipe 2, it can rotate along the spiral auger 11 to extend the flow stroke of the water flow, slow down the impact force of the water flow, and thus reduce the impact of the water flow on the protective plate 7, thereby extending the service life of the protective plate 7. A fixed cone 12 is fixedly connected to the top of the cylinder 10. When the water reaches the upper end of the cylinder 10, it can slide along the tip surface of the fixed cone 12 and enter the spiral auger. In 11, the obstruction of the cylinder 10 to the flow of water is reduced, and a protective ring 13 is fixedly connected to the bottom of the feed pipe 2. The protective ring 13 is located below the spiral auger 11. The cross-section of the protective ring 13 is a triangular structure. When the water flows to the protective ring 13, it can flow along the inclined surface of the protective ring 13 toward the center of the pipe, so that the water flow directly impacts the protective plate 7 more, reducing the impact of the water flow on the protective rubber ring 8, avoiding the protective rubber ring 8 from being subjected to a large amount of impact for a long time, resulting in deformation and inability to recover, which in turn affects the disassembly of the protective plate 7.

[0037] Working principle: when water flows through the feed pipe 2, it can enter the spiral auger 11 to flow in a threaded manner, thereby increasing the stroke of the water flow and reducing the impact force of the water flow. When the water flows through the spiral auger 11 and reaches the protective ring 13, it can flow along the inclined surface of the protective ring 13 into the bending tube 1, and more flow can impact the protective plate 7. The bending part of the bending tube 1 is protected by the provided protective plate 7 to prevent the water flow from impacting the bending part of the bending tube 1 for a long time, thereby affecting the service life of the bending tube 1. When the protective plate 7 is worn after long-term use, the rotating ring plate 62 can be directly screwed and the handle 72 can be held tightly to drive the protective plate 7 to move downward and leave the bending tube 1 for replacement. The operation is simple and the entire pipe fitting cannot be disassembled and replaced, thereby reducing the maintenance cost.
