Description

Technical Field

[0001] This utility model relates to the field of elbow technology, specifically an impact-resistant elbow. Background Technology

[0002] In piping systems, elbows are pipe fittings used to change the direction of pipelines. They are a commonly used connection fitting in pipeline installation. Due to their excellent comprehensive performance, elbow fittings are widely used in basic engineering projects such as chemical, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, power, aerospace, and shipbuilding.

[0003] The prior art, disclosed in CN 216743365 U, describes a novel three-in-one impact-resistant and wear-resistant elbow. This device improves the elbow's impact resistance by using composite materials. However, with long-term use, the elbow will be damaged by the impact and corrosion of the conveying medium. Furthermore, the medium will directly impact the elbow during the conveying process, causing it to vibrate and loosen. In addition, during liquid conveying, fine particulate impurities in the liquid will impact the inner wall of the elbow under the influence of the water flow, causing severe wear and reducing the elbow's service life. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies where direct liquid impact on elbows and particulate impurities increase elbow wear, and to provide an impact-resistant elbow.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an impact-resistant elbow, comprising a bent pipe body, flanges fixedly connected to both ends of the pipe body, a buffer plate provided inside the pipe body, the buffer plate being an arc-shaped plate with a semi-circular cross-section, a plurality of barrier plates provided on the inner side of the buffer plate, and the buffer plate and the barrier plates being integrally connected, the buffer plate and the barrier plates being elastic rubber plates, an opening provided on the pipe body, the opening being located on one side of the outer diameter, a cover plate provided at the opening, the cover plate being an arc-shaped plate with a semi-circular cross-section, and the cover plate being fixed to the opening of the pipe body by bolts, the buffer plate being fixedly connected to the inner side of the cover plate, and filters being provided inside the pipe body near both ends.

[0006] As described above, the pipe body is fixedly connected to the front and rear sides with a first connecting plate, and the first connecting plate has a slot. The cover plate is fixedly connected to the front and rear sides with a second connecting plate, and the second connecting plate fits into the slot.

[0007] As described above, a first sealing gasket is fixedly connected to the second connecting plate, and the first sealing gasket is in close contact with the first connecting plate. Both the first and second connecting plates have through holes, and the bolt is located in the through holes.

[0008] As described above, the tube body is provided with two sets of baffles, which are distributed on both sides of the opening. The baffles are annular plates, and there are two baffles in each set. The two baffles are fixedly connected to the tube body and the baffle respectively. The filter is snapped between the two baffles in the adjacent set.

[0009] The filter described above includes a fixed plate and a movable plate. The fixed plate is an annular plate sandwiched between two partitions. A second sealing gasket that is in close contact with the fixed plate is fixedly connected to the partitions. A filter screen is fixedly connected between the fixed plate and the movable plate.

[0010] As described above, the filter screen is cylindrical, with a spring inside. Both ends of the filter screen and the spring are fixedly connected to the fixed plate and the movable plate, respectively. The filter screen and the spring pass through the inside of the partition.

[0011] As described above, the fixing plate of the filter is arranged facing the water inlet of the elbow, and several integrated reinforcing plates are provided on the outer side of the cover plate.

[0012] Compared with existing technologies, this impact-resistant elbow has the following advantages:

[0013] I. This utility model uses a buffer plate and a barrier plate made of elastic rubber on one side of the inner and outer diameter of the pipe. When the liquid passes through the elbow, the barrier plate and the buffer plate come into contact with the liquid in sequence. When the barrier plate and the buffer plate are impacted, they deform and generate elastic force to offset the impact of the liquid, thereby reducing the impact on the pipe body, protecting the pipe body, reducing damage to the pipe body, and reducing the vibration generated by the impact, making the elbow less likely to loosen.

[0014] Second, this utility model provides an opening on the pipe body and a cover plate at the opening, with the buffer plate located on the cover plate. This allows the buffer plate to be replaced individually by removing the cover plate, without disassembling the entire elbow, which facilitates maintenance and reduces maintenance costs.

[0015] Third, this utility model has two sets of baffles in the tube body, and each set of baffles is fitted with a filter consisting of a fixed plate, a movable plate and a filter screen, which can filter particulate impurities in the liquid, reduce the impact of impurities on the buffer plate under high-speed flow, reduce the wear of the buffer plate, and the filter is equipped with a spring to further reduce the impact of water flow.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution for an impact-resistant elbow: an impact-resistant elbow includes a bent pipe body 1, flanges fixedly connected to both ends of the pipe body 1, a buffer plate 6 provided inside the pipe body 1, the buffer plate 6 being an arc-shaped plate with a semi-circular cross section, a plurality of barrier plates 7 provided on the inner side of the buffer plate 6, and the buffer plate 6 and the barrier plates 7 being integrally connected, both the buffer plate 6 and the barrier plates 7 being elastic rubber plates, an opening being provided on the pipe body 1, and the opening being located on one side of the outer diameter, a cover plate 2 being provided at the opening, the cover plate 2 being an arc-shaped plate with a semi-circular cross section, and the cover plate 2 being fixed to the opening of the pipe body 1 by bolts 12, the buffer plate 6 being fixedly connected to the inner side of the cover plate 2, and filters 8 being provided inside the pipe body 1 near both ends.

[0024] According to the overall structure of the device, during use, the elbow is installed on the conveying pipeline through the flange, and the inlet direction of the filter 8 is the same as the inlet direction of the elbow. When the liquid enters from the inlet and passes through the filter 8, the filter 8 filters out the fine particles in the liquid, preventing the particles from impacting the buffer plate 6 and the barrier plate 7 under the drive of the water flow, thus increasing the wear of the components. Afterwards, the water flow impacts the barrier plate 7 and the buffer plate 6. The barrier plate 7 and the buffer plate 6 deform after being impacted, offsetting the impact of the water flow, thereby reducing the impact transmitted to the pipe body 1, thus protecting the elbow.

[0025] like Figure 2 , 3 As shown, the pipe body 1 is fixedly connected to the front and rear sides with a first connecting plate 3, and the first connecting plate 3 has a slot. The cover plate 2 is fixedly connected to the front and rear sides with a second connecting plate 4, and the second connecting plate 4 fits into the slot. The second connecting plate 4 is fixedly connected to a first sealing gasket 10, and the first sealing gasket 10 is in close contact with the first connecting plate 3. The first connecting plate 3 and the second connecting plate 4 are both provided with through holes, and the bolt 12 is located in the through holes.

[0026] The connection surface between the cover plate 2 and the pipe body 1 is increased by the first connecting plate 3 and the second connecting plate 4, and the cover plate 2 is fixed by bolts 12 to improve the stability of the cover plate 2 during installation. The bolts 12 also facilitate the disassembly and assembly of the cover plate 2, thereby facilitating the maintenance of the internal components of the elbow. The gap between the cover plate 2 and the pipe body 1 is sealed by the first sealing gasket 10 to prevent liquid leakage.

[0027] like Figure 2 , 3 As shown, the tube body 1 is provided with two sets of partitions 9, which are distributed on both sides of the opening. The partitions 9 are annular plates, and there are two partitions in each set. The two partitions 9 are fixedly connected to the tube body 1 and the partitions 9 respectively. The filter 8 is snapped between the two partitions 9 of the adjacent set. The filter 8 includes a fixed plate 801 and a movable plate 802. The fixed plate 801 is an annular plate and is sandwiched between the two partitions 9. A second sealing gasket 11 is fixedly connected to the partition 9 and is in close contact with the fixed plate 801. A filter screen 803 is fixedly connected between the fixed plate 801 and the movable plate 802. The filter screen 803 is cylindrical and has a spring 804 on the inner side. Both ends of the filter screen 803 and the spring 804 are fixedly connected to the fixed plate 801 and the movable plate 802 respectively. The filter screen 803 and the spring 804 pass through the inner side of the partition 9.

[0028] The filter 8, consisting of the movable plate 802, filter screen 803, and fixed plate 801, can filter fine particulate impurities in the liquid, preventing them from impacting the elbow and causing wear. The fixed plate 801 is clamped and fixed by the partition plate 9 to prevent the filter 8 from moving under the impact of the water flow and to facilitate the disassembly and replacement of the filter 8. The second sealing gasket 11 seals the space between the fixed plate 801 and the partition plate 9, improving the filtration effect. The spring 804 connects the movable plate 802 and the fixed plate 801, so that when water flows into the filter 8, the water flow impacts the movable plate 802 and causes the spring 804 to stretch, thereby offsetting the impact of the water flow through elasticity.

[0029] The fixing plate 801 of the filter 8 is set towards the water inlet of the elbow, and several integrated reinforcing plates 5 are set on the outside of the cover plate 2.

[0030] By aligning the fixed plate 801 with the water inlet, the water flow can impact the movable plate 802 to unfold the filter screen 803, preventing the water flow from impacting the movable plate 802 and sticking to the partition plate 9 when placed in reverse, thus preventing the pipe body 1 from becoming unconductive. The strength of the cover plate 2 is increased by the reinforcing plate 5.

[0031] Working principle: In use, the elbow is installed on the conveying pipeline through the flange, and the inlet direction of the filter 8 is the same as the inlet direction of the elbow. When the liquid enters from the inlet and passes through the filter 8, the filter 8 filters out the fine particles in the liquid, preventing the particles from impacting the buffer plate 6 and the baffle plate 7 under the action of the water flow, thus increasing the wear of the components. At the same time, the water flow impacts the movable plate 802, causing the movable plate 802 to stretch the spring 804. The elastic force of the spring 804 slows down the water flow. Then the water flow impacts the baffle plate 7 and the buffer plate 6. After being impacted, the baffle plate 7 and the buffer plate 6 deform to offset the impact of the water flow, thereby reducing the impact transmitted to the pipe body 1, thus protecting the elbow. The cover plate 2 can be removed by bolt 12, so that the filter 8 and the buffer plate 6 can be maintained and replaced.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
