Description

Technical Field

[0001] This utility model belongs to the field of pulse damper technology, specifically, it relates to a pulse damper. Background Technology

[0002] A pulse damper is a pressure vessel used to eliminate pressure or flow pulsations in pipelines. It functions to stabilize fluid pressure and flow, eliminate pipeline vibration, protect downstream instruments and equipment, and increase pump volumetric efficiency. Diaphragm pulse dampers are a common type. They use a corrosion-resistant diaphragm to isolate the gas from the liquid in the pipeline. By changing the volume of the gas chamber, they smooth pipeline pulsations, thereby reducing the damage of water hammer to the system, minimizing peak flow velocity fluctuations, protecting pipelines and valve joints from pressure fluctuations, and reducing system energy consumption.

[0003] Chinese Patent No. CN222797636U discloses a diaphragm-type pulse damper, comprising a diaphragm-type pulse damper body. Both the top and bottom ends of one side of the diaphragm-type pulse damper body have connection ports for connecting pipes. A hollow tube is fixedly mounted on the top of the diaphragm-type pulse damper body, and the hollow tube is sleeved outside the first connection port. A sleeve is provided on the top of the hollow tube, and a first semi-circular groove is formed between the bottom end of the sleeve and the top end of the hollow tube. This invention protects the diaphragm-type pulse damper body's instruments, connection ports, and pipes on the top of the diaphragm-type pulse damper body using a sleeve and a hollow tube, thereby improving the firmness of the connection between the pipes and the connection ports and preventing leakage. Two semi-circular shells are then used to protect the connection ports and pipes at the bottom of the diaphragm-type pulse damper body from leakage. Multiple first buckles connect the sleeve and the hollow tube, facilitating the disassembly of the sleeve for maintenance.

[0004] However, in actual use, the aforementioned comparative documents require the hollow tube to be fixedly connected to the pulse damper body, which affects subsequent maintenance. If the hollow tube is damaged, the pulse damper will be unable to be used or the use of the pulse damper will need to be stopped to repair the hollow tube, which is a rather troublesome repair process.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a pulse damper that solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A pulse damper includes: a pulse damper body, with connecting pipes connected to the top side and bottom of the pulse damper body, two fixed bases detachably mounted on the pulse damper body, an upper protective shell detachably mounted on the upper side of the pulse damper body, and a lower protective shell detachably mounted on the lower side of the pulse damper body.

[0009] The fixed base includes a fixed collar with two rotating rings rotatably fitted on it. Multiple protrusions are installed on the opposite outer sides of the two rotating rings. Multiple first connecting ropes are detachably installed on the fixed collar, and a first hook is installed at the end of each first connecting rope.

[0010] Optionally, the cross-section of the protrusion is a right trapezoid, and a slot is provided on the upper surface of the right trapezoid.

[0011] Optionally, a plurality of first T-shaped grooves are provided on one side of the fixing collar, and a first T-shaped locking block is installed at one end of the first connecting rope.

[0012] Optionally, hook gaps are provided on both the retaining collar and the protrusion.

[0013] Optionally, the upper protective shell includes a transparent barrel and multiple second T-shaped blocks. Multiple second T-shaped grooves are provided on the upper side of the transparent barrel. A second connecting rope is installed at one end of the second T-shaped block, and a second hook is installed at the end of the second connecting rope.

[0014] Optionally, a first semi-circular groove is provided on the inner side of both the transparent barrel and one of the fixing collars.

[0015] Optionally, the lower protective housing includes two semi-cylindrical shells and multiple third T-shaped blocks. Multiple connectors are provided between the two semi-cylindrical shells. Multiple third T-shaped grooves are opened on one side of the two semi-cylindrical shells. A third connecting rope is installed at one end of the third T-shaped block, and a third hook is installed at the end of the third connecting rope.

[0016] Optionally, the semi-barrel-shaped outer shell includes arc-shaped side plates and a semi-circular bottom plate, with a second semi-circular groove formed on the semi-circular bottom plate.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0018] 1. With the detachable design of the fixed base, upper protective shell, and lower protective shell, the components can be assembled step by step during installation without the need for special tools, reducing the difficulty of on-site construction; during operation and maintenance, the protective components can be quickly disassembled, greatly shortening the downtime for maintenance and improving the operation and maintenance efficiency throughout the entire life cycle of the equipment.

[0019] 2. With the flexible connection of T-blocks, T-slots, and hooks, different sizes and models of pulse dampers can be adapted without changing the main design of the protective structure. This effectively expands the application scenarios of the product, reduces the cost of repeated purchases of protective devices due to differences in equipment specifications, and improves resource utilization.

[0020] 3. The upper and lower protective shells, together with the fixed base, form a protective enclosure from the top, bottom, and circumference, creating a physical barrier for the pulse damper body and connecting pipes. This effectively resists external collisions and impact loads, prevents foreign objects from falling in, reduces the risk of equipment failure due to external force damage, and extends the service life of the pulse damper.

[0021] 4. The upper protective shell adopts a transparent barrel structure, which, while providing physical protection, supports visual observation of the operating status of key components on the upper part of the damper (such as associated pressure monitoring and pipeline connection areas). Daily inspections can be completed without removing the protective structure, facilitating the timely detection of abnormal operating conditions (such as pipeline leakage, abnormal pressure deformation, etc.), and achieving integrated and unified protection and monitoring functions;

[0022] 5. Utilizing a mechanical tensioning mechanism composed of a swivel and protrusions, combined with dual limiting via a T-shaped connection, hook, and slot, a reliable clamping force is formed between the protective components and the pulse damper body. Even under continuous vibration and external disturbance conditions, a tight fit is maintained, preventing the protective structure from loosening and failing, ensuring continuous and stable protective performance, and laying a solid foundation for the reliable operation of the damper.

[0023] 6. The rotating ring, combined with the design of the protruding bevel and slot, allows for flexible adjustment of the tension of the protective components according to on-site installation errors and protection requirements. The expandable connection method, featuring T-blocks, T-slots, and multiple hooks, supports adding or removing connecting ropes as needed, achieving compatibility between the protective structure and the damper body, and optimizing the protective effect.

Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings.

[0035] Please see Figure 1-5 As shown, this embodiment provides a pulse damper, including: a pulse damper body 1, with connecting pipes 2 connected to the top side and bottom of the pulse damper body 1, two fixed bases 3 detachably installed on the pulse damper body 1, an upper protective shell 4 detachably installed on the upper side of the pulse damper body 1, and a lower protective shell 5 detachably installed on the lower side of the pulse damper body 1.

[0036] The fixed base 3 includes a fixed collar 6, on which two rotating rings 7 are rotatably fitted. Multiple protrusions 8 are installed on the opposite outer sides of the two rotating rings 7. Multiple first connecting ropes 9 are detachably installed on the fixed collar 6, and a first hook 10 is installed at the end of the first connecting rope 9.

[0037] The pulse damper body 1 is detachably connected to the fixed base 3, upper protective housing 4, and lower protective housing 5. During installation, the fixed base, protective housing, and body can be assembled in steps without any destructive modifications to the body. For subsequent maintenance, such as cleaning the body and inspecting the connecting pipe 2, the corresponding components can be quickly removed, greatly simplifying the disassembly and assembly process and improving the convenience of equipment operation and maintenance.

[0038] In the fixed base 3, the fixed collar 6 is connected to the pulse damper body 1 via the first connecting rope 9 and the first hook 10. Combined with the structure of the swivel ring 7 and the protrusion 8, the tension and fixed position of the connecting rope can be flexibly adjusted. Compared to traditional rigid connections, this can accommodate installation errors of the body or dynamic fixing requirements under different working conditions such as vibration environments, enhancing connection adaptability.

[0039] When the rotating ring 7 rotates, the protrusion 8 can cooperate with the first hook 10, and the inclined surface of the protrusion 8 can achieve the pre-tightening effect of tightening the connecting rope and engaging the hook into the slot. This makes the connection between the fixed base 3 and the body 1 tighter, effectively resisting external vibration and minor impacts, reducing the risk of protection failure due to loose connection, and strengthening the basic protection of the pulse damper body.

[0040] In this embodiment, the protrusion 8 has a right-angled trapezoidal cross-section, and a slot is provided on the upper surface of the right-angled trapezoid. The fixing collar 6 in this embodiment has multiple first T-shaped slots 11 on one side, and a first T-shaped locking block 12 is installed at one end of the first connecting rope 9. Both the fixing collar 6 and the protrusion 8 in this embodiment have hook gaps 13. The protrusion 8 has a right-angled trapezoidal cross-section and a slot on its upper surface. When the first hook 10 moves along the inclined plane to the slot, precise positioning and automatic locking can be achieved. During installation, only the rotating ring 7 needs to be rotated, and the first hook 10 can quickly embed into the slot under the guidance of the protrusion 8. Compared with traditional fixing methods, this significantly reduces installation and adjustment time, improves assembly efficiency, and effectively prevents loosening of the connection. The fixing collar 6 has a first T-shaped slot 11, which, together with the first T-shaped locking block 12 at the end of the first connecting rope 9, enables a detachable connection between the connecting rope and the fixing collar 6. During installation, the number and position of the first connecting rope 9 can be flexibly adjusted to adapt to different specifications of the pulse damper body 1. Disassembly is simple; the first T-shaped clip 12 can be pulled out directly, facilitating equipment maintenance and component replacement. The fixing collar 6 and protrusion 8 have a hook gap 13, providing a dedicated embedding channel for the first hook 10, preventing interference between the hook and other structures and ensuring a stable hook installation. Simultaneously, this gap design ensures more even force distribution on the hook, and combined with the locking slot, effectively resists external forces such as vibration and impact during equipment operation, preventing the connecting rope from falling off and ensuring the long-term reliable operation of the pulse damper's protective structure.

[0041] The upper protective shell 4 of this embodiment includes a transparent barrel 14 and a plurality of second T-shaped blocks 17. The upper side of the transparent barrel 14 is provided with a plurality of second T-shaped grooves 16. A second connecting rope 18 is installed at one end of the second T-shaped block 17, and a second hook 19 is installed at the end of the second connecting rope 18. The transparent barrel 14 and one of the fixing collars 6 in this embodiment are provided with a first semi-circular groove 15 on their respective inner sides.

[0042] The lower protective housing 5 in this embodiment includes two semi-cylindrical shells 20 and multiple third T-shaped blocks 21. Multiple connectors 22 are provided between the two semi-cylindrical shells 20. Multiple third T-shaped grooves 25 are formed on one side of each semi-cylindrical shell 20. A third connecting rope 23 is installed at one end of each third T-shaped block 21, and a third hook 24 is installed at the end of each third connecting rope 23. The semi-cylindrical shell 20 in this embodiment includes an arc-shaped side plate 26 and a semi-circular bottom plate 27. A second semi-circular groove 28 is formed on the semi-circular bottom plate 27. The lower protective housing 5 adopts a structure in which two semi-cylindrical shells 20 are spliced ​​together by connectors 22, which reduces the installation difficulty compared to a one-piece molded shell. During installation, the pulse damper body 1 and connecting pipe 2 can be wrapped from both sides and quickly fixed by the connector 22. During disassembly, the semi-barrel-shaped outer shell 20 can be disassembled separately to facilitate inspection and cleaning of the bottom of the damper and the connecting pipe 2, greatly shortening maintenance time and improving equipment operation and maintenance efficiency. The third T-shaped groove 25 set on the semi-barrel-shaped outer shell 20 cooperates with the third T-shaped block 21 to flexibly adjust the installation position of the third connecting rope 23. The third hook 24 at the end of the third connecting rope 23 can be connected to the corresponding structure on the fixed base 3. By tightening the third connecting rope 23, the lower protective shell 5 can be tightly fitted to the pulse damper body 1. This design can accommodate dampers of different sizes and remain secure under vibration conditions, preventing the protective shell from loosening and falling off. The semi-circular bottom plate 27 of the semi-barrel-shaped shell 20 has a second semi-circular groove 28, which matches the shape of the connecting pipe 2 at the bottom of the pulse damper body 1. This can form a precise wrap around the connecting pipe 2, effectively blocking external collisions, impacts and foreign object intrusion, and protecting the connecting pipe 2 from damage. At the same time, the second semi-circular groove 28 also plays a positioning role, helping the semi-barrel-shaped shell 20 to be installed quickly and accurately, improving assembly accuracy.

[0043] like Figure 4-5 As shown, in this embodiment, a ratchet toothed ring is installed on the outer wall of the fixing collar 6. A lever is rotatably engaged inside the rotating ring 7, and a pressure rod is slidably engaged inside the rotating ring 7. The pressure rod engages with the lever, and the lever engages with the ratchet toothed ring through a torsion spring. The ratchet toothed ring on the outer wall of the fixing collar 6 engages with the lever and the torsion spring. When the rotating ring 7 rotates and tightens the first connecting rope 9, the lever engages with the ratchet toothed ring in one direction under the action of the torsion spring, forming an irreversible locking state. This design can effectively prevent the rotating ring 7 from rotating in the opposite direction due to equipment vibration or external impact, avoid loosening of the connecting rope, ensure the long-term stable connection between the pulse damper fixing base 3 and the body 1, and improve the reliability of the protective structure.

[0044] Working principle:

[0045] In use, first install the two fixed bases 3 on the upper and lower sides of the pulse damper body 1. Then, insert the first connecting rope 9 into the first T-shaped groove 11 through the first T-shaped clip 12 at the end to complete the installation of the first connecting rope 9. Then, hang multiple first connecting ropes 9 in the hook gap 13 on the other fixed base 3 through the first hook 10. At this time, rotate the rotating ring 7 on the two fixed bases 3. The rotating ring 7 rotates to make the first hook 10 be tightened through the inclined surface of the protrusion 8 and embedded in the slot to complete the fixation. Then, cover the upper protective shell 4 on the upper side of the pulse damper body 1, and connect the second connecting rope 18 to one of the fixed bases 3 through the second hook 19 in the above manner. The components are tightly connected, and one of the connecting pipes 2 is connected and clamped to the upper protective shell 4 and one of the fixed bases 3 through the first semi-circular groove 15. Then, the two semi-cylindrical shells 20 of the lower protective shell 5 are spliced ​​together through the connector 22, and the other connecting pipe 2 is connected and clamped through the second semi-circular groove 25 on the semi-circular base plate 27. Referring to the above method, the third connecting rope 23 is tightened through the third hook 24, so that the lower protective shell 5 is tightly connected to the other fixed base 3. Thus, the two fixed bases 3, the upper protective shell 4, and the lower protective shell 5 can be installed on the pulse damper body 1.
