Description

Technical Field

[0001] The utility model relates to the technical field of pipe fittings, in particular to a slow-flow impact-resistant elbow pipe fitting. Background Art

[0002] In the early pipeline system, elbow fittings were mainly used to change the direction of water flow, but they were often susceptible to the impact and vibration of water flow, resulting in damage and leakage. With the development of technology and the improvement of people's requirements for pipeline systems, the design and materials of elbow fittings have been continuously improved. In the mid-20th century, with the popularization of plastic pipes, people began to explore the use of plastic elbow fittings. Plastic pipes have the advantages of being light, corrosion-resistant, and not easy to rust, which can greatly improve the service life of elbow fittings. At the same time, the design of plastic elbow fittings has also been improved. By adding impact-resistant materials and optimizing the internal structure, the slow flow and impact resistance of elbow fittings have been improved. After entering the 21st century, with the improvement of people's requirements for environmental protection and energy saving, the materials and designs of elbow fittings have been continuously optimized. New slow-flow and impact-resistant elbow fittings began to appear. They use high-performance materials and advanced production processes, and have better slow flow, impact resistance, leak-proof, shock-proof and other properties. At the same time, these elbow fittings also have good environmental protection performance and can meet the various complex needs of modern pipeline systems. In summary, the development history and historical background of slow-flow impact-resistant elbow pipe fittings is a process of continuous improvement and innovation. With the continuous advancement of technology and the continuous improvement of application needs, slow-flow impact-resistant elbow pipe fittings will be more widely used and developed.

The installation of slow-flow impact-resistant elbow fittings needs to strictly comply with certain standards and specifications, otherwise problems caused by improper installation, such as leakage, blockage, etc., are likely to occur. Secondly, maintenance is more complicated: The structure of slow-flow impact-resistant elbow fittings is more complex, requiring regular maintenance and maintenance, and the maintenance process is relatively complicated, requiring professional personnel to operate. Finally, the service life is limited: The service life of slow-flow impact-resistant elbow fittings is affected by many factors, such as material quality, use environment, installation quality, etc. Therefore, its service life is limited and needs to be replaced regularly.

[0014] Preferably, the water inlet interface and the water outlet interface are respectively equipped with a water inlet pipe and a water outlet pipe.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a slow-flow impact-resistant elbow pipe fitting, which has the following beneficial effects:

[0017] 1. The slow-flow and impact-resistant elbow pipe fitting is used in conjunction with the water inlet pipe, the gradually widening water inlet pipe and the slow-flow and impact-resistant elbow pipe. When a large amount of water enters the gradually widening water inlet pipe from the water inlet pipe and then enters the slow-flow and impact-resistant elbow pipe, if the diameter of the traditional elbow pipe fitting is the same as the diameter of the water inlet pipe, the water flow rate from the water inlet pipe into the elbow pipe fitting is very fast, which can easily form a large impact force on the outside of the elbow pipe fitting. Over time, the inner wall of the elbow pipe fitting impacted by the water flow will be damaged. In this patent, the water entering from the water inlet pipe passes through the gradually widening water inlet pipe. Since the diameter of one end of the gradually widening water inlet pipe is smaller and the diameter of the other end is larger, the water flow from the smaller diameter end to the larger diameter end will have a much smaller impact force on the inner wall of the slow-flow and impact-resistant elbow pipe due to the larger cross-sectional area of ​​the pipe passing through. Thereby, the life span is greatly increased and it is not easy to be damaged.

[0018] 2. The slow-flow impact-resistant elbow pipe fittings are used in conjunction with non-Newtonian fluid rings and thickened pipe walls. When a large amount of water flows into the slow-flow impact-resistant elbow pipe, most of the water will rush to the inner wall on the side with a larger curvature, so thickening the pipe wall on that side can effectively prevent long-term scouring. In addition, the non-Newtonian fluid ring set inside the slow-flow impact-resistant elbow pipe, when a large amount of water flows into the slow-flow impact-resistant elbow pipe, there is a large amount of force in the water flow, and this force will act on the non-Newtonian fluid ring. At this time, due to the characteristics of non-Newtonian fluids, the greater the force acting on the non-Newtonian fluid, the harder the non-Newtonian fluid, so the faster the water flow rate inside the slow-flow impact-resistant elbow pipe, the better the protection performance of the non-Newtonian fluid ring on the slow-flow impact-resistant elbow pipe. Thereby achieving the effect of greatly increasing the service life and not being easily damaged.

[0019] 3. The slow-flow impact-resistant elbow pipe fitting is used in conjunction with the water inlet interface, the water outlet interface, the water inlet pipe and the water outlet pipe. Since the water inlet pipe and the water outlet pipe are directly inserted into the water inlet interface and the water outlet interface respectively, a certain sealing strip can be wrapped around the connection surface of the water inlet interface and the water outlet interface to prevent water leakage during insertion. Thus, the installation requirements are low and the installation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-4, a slow-flow impact-resistant elbow pipe fitting comprises a slow-flow impact-resistant elbow pipe 1, a water outlet interface 5 and a water inlet interface 4. The slow-flow impact-resistant elbow pipe 1 can play a role in slowing down flow and preventing water flow impact. The slow-flow impact-resistant elbow pipe 1 is in the shape of a right-angled arc as a whole, and the slow-flow impact-resistant elbow pipe 1 is a hollow structure. The right-angled ends of the slow-flow impact-resistant elbow pipe 1 are respectively provided with a water inlet gradually widening pipe 2 and a water outlet gradually widening pipe 3. The shapes of the water inlet gradually widening pipe 2 and the water outlet gradually widening pipe 3 are the same, and both are gradually widening conical structures with a smaller diameter at one end and a larger diameter at the other end and are hollow. The larger diameter ends of the water inlet gradually widening pipe 2 and the water outlet gradually widening pipe 3 are interconnected with the slow-flow impact-resistant elbow pipe 1, and the interior of the slow-flow impact-resistant elbow pipe 1 is provided with a non-Newtonian fluid ring 12 with the same internal shape and attached to its inner wall. The slow-flow impact-resistant elbow pipe 1 has the function of slowing down flow. Through its right-angled arc shape, the direct water flow can be converted into a slow water flow, reducing the impact force of the water flow. By changing the direction of water flow, it also plays a buffering role, and by reducing the water flow speed through the larger internal cross-street area, the impact on the pipe wall is reduced. The function of the gradually widening water inlet pipe 2 and the gradually widening water outlet pipe 3 is buffering. The gradually widening cone structure with a smaller diameter at one end and a larger diameter at the other end can further slow down the speed of the water flow and make the water flow more stable. Together with the slow-flow and impact-resistant elbow 1, a double buffer structure is formed to further reduce the impact of the water flow on the pipe wall. Non-Newtonian fluid ring 12: Utilizing the characteristics of non-Newtonian fluid, the non-Newtonian fluid will become very hard when impacted. Therefore, when the water flow continuously impacts the non-Newtonian fluid ring 12, its hardness will be very high and can well protect the slow-flow and impact-resistant elbow 1. The non-Newtonian fluid ring 12 fits tightly with the inner wall, and the non-Newtonian fluid ring 12 can be dynamically adjusted with the water flow to improve the slow-flow and impact-proof effects of the elbow pipe fittings.

[0027] The diameter of the hollow part inside the slow-flow and impact-resistant bend pipe 1 is larger than the diameter of the water inlet pipe 6, and the diameter of the hollow part inside the slow-flow and impact-resistant bend pipe 1 is equal to the diameter of the larger end of the water inlet gradually widening pipe 2. The diameter of the hollow part inside the slow-flow and impact-resistant bend pipe 1 is larger than the diameter of the water inlet pipe 6. Such a design can make the cross-sectional area of ​​the water flow larger when passing through the slow-flow and impact-resistant bend pipe 1, thereby reducing the flow rate and reducing the impact force on the internal pipe wall.

[0028] The slow-flow impact-resistant curved pipe 1 has a thickened pipe wall 8 on one side of a larger arc, and a normal pipe wall 9 on the other side opposite to the thickened pipe wall 8. The thickened pipe wall can effectively resist the impact of water flow.

[0029] A water retaining and retarding ring 11 and a limiting ring 10 are arranged on the inner end surface of the end with a larger diameter of the water inlet gradually widening pipe 2 and the water outlet gradually widening pipe 3. A non-Newtonian fluid ring 12 is embedded between the water retaining and retarding ring 11 and the limiting ring 10. The water retaining and retarding ring 11 can decelerate the water flow entering from the water inlet gradually widening pipe 2 to a certain extent, reducing the impact force on the inner wall of the pipe. The combined action of the water retaining and retarding ring 11 and the limiting ring 10 can limit the position of the non-Newtonian fluid ring 12, so that it remains in the correct position inside the slow-flow and impact-resistant elbow 1.

[0030] The non-Newtonian fluid ring 12 is a right-angled annular capsule, and non-Newtonian fluid is filled inside the capsule. The non-Newtonian fluid ring 12 is a right-angled annular capsule, and this shape is to make it adapt to the shape of the inside of the slow-flow and impact-resistant pipe, and easier to install. In addition, the shape of the capsule is easier to add non-Newtonian fluid, and when it is impacted by water flow, it can more completely receive the impact force of the water flow, so that the non-Newtonian fluid hardens and better protects the inner wall of the pipe.

[0031] The ends of the water inlet gradually widening pipe 2 and the water outlet gradually widening pipe 3 with smaller diameters are respectively provided with a water inlet interface 4 and a water outlet interface 5. The water inlet interface 4 and the water outlet interface 5 are respectively equipped with a water inlet pipe 6 and a water outlet pipe 7. The water inlet pipe 6 and the water outlet pipe 7 are installed in the water inlet interface 4 and the water outlet interface 5 by insertion, and certain waterproof work is done.

[0032] Working principle: When in use, first insert the water inlet pipe 6 and the water outlet pipe 7 into the water inlet interface 4 and the water outlet interface 5, and make sure they are waterproof. Since the water inlet pipe 6 and the water outlet pipe 7 are directly inserted into the water inlet interface 4 and the water outlet interface 5, a certain sealing strip can be wrapped around the connection surface of the water inlet interface 4 and the water outlet interface 5 to prevent water leakage.

[0033] When a large amount of water enters the gradually widening water inlet pipe 2 from the water inlet pipe 6 and then enters the slow-flow and impact-resistant elbow pipe 1, if the internal diameter of the traditional elbow pipe is the same as the diameter of the water inlet pipe 6, the water flow from the water inlet pipe 6 into the elbow pipe is very fast, which can easily form a large impact force on the outside of the elbow pipe. Over time, the inner wall of the elbow pipe impacted by the water flow will be damaged. In this patent, the water entering from the water inlet pipe 6 passes through the gradually widening water inlet pipe 2. Since the diameter of one end of the gradually widening water inlet pipe 2 is smaller and the diameter of the other end is larger, the water flow from the smaller diameter end to the larger diameter end will have a larger cross-sectional area through the pipe and a slower flow rate, and the impact force on the inner wall of the slow-flow and impact-resistant elbow pipe 1 will be much smaller.

[0034] When a large amount of water flows into the slow-flow and impact-resistant bend pipe 1, most of the water will rush to the inner wall on the side with a larger curvature, so thickening the wall on this side can effectively prevent long-term scouring. In addition, the non-Newtonian fluid ring 12 is set inside the slow-flow and impact-resistant bend pipe 1. When a large amount of water flows into the slow-flow and impact-resistant bend pipe 1, there is a large amount of force in the water flow, and this force will act on the non-Newtonian fluid ring 12. At this time, due to the characteristics of the non-Newtonian fluid, the greater the force acting on the non-Newtonian fluid, the harder the non-Newtonian fluid, so the faster the water flow velocity inside the slow-flow and impact-resistant bend pipe 1, the better the protection performance of the non-Newtonian fluid ring 12 on the slow-flow and impact-resistant bend pipe 1.
