Description

Technical Field

[0001] This utility model relates to the field of pipeline vibration reduction technology, and in particular to pipeline fluid dampers. Background Technology

[0002] In industrial production, pipeline systems are widely used to transport various fluid media, such as liquids and gases. Because fluids flow through pipelines, they generate pulsations, which can cause pipeline vibrations. Prolonged vibration can not only affect the normal operation of the pipeline system but also lead to loosening of pipe connections, fatigue damage, and even safety accidents such as leaks. To effectively address pipeline vibration problems, pipeline dampers have been developed. They are devices specifically designed to reduce and eliminate pressure shocks and vibrations caused by the flow of liquids or gases in pipeline systems.

[0003] Existing in-line fluid dampers typically consist of a pipe and an internal piston. When liquid or gas flows through the pipe, the piston is subjected to the impact force of the fluid, resulting in vibration and pressure fluctuations. In-line dampers absorb and disperse these impact forces by regulating the movement of the piston, thereby reducing the effects of pressure fluctuations and vibrations.

[0004] However, in-line dampers require a certain amount of space for installation, especially for larger diameter pipeline systems; during use, in-line dampers may be affected by impurities and corrosive substances in the fluid, leading to damage to the piston and other components inside the damper, requiring regular maintenance and cleaning; in-line dampers consume energy to absorb and disperse impact forces, which may increase the system's energy consumption; in-line dampers may not be suitable for certain special working conditions or media, such as high temperature, high pressure, or corrosive media; compared to other vibration reduction devices, in-line dampers are more expensive, including the cost of the equipment itself, installation costs, and maintenance costs. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a pipeline fluid damper that is easy to disassemble and clean, simple to maintain and low in cost, and is used to stabilize fluid pressure and flow rate.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] The pipeline fluid damper includes a housing; it also includes a foamed material filler installed inside the housing, a gland installed on the housing, a rubber diaphragm installed inside the foamed material filler, and a chuck interface installed on the housing.

[0008] In one optional embodiment, the rubber tube in the middle of the rubber diaphragm is tubular and sleeved on the inner ring of the foamed material filler, and the two ends of the rubber diaphragm extend outward to form sealing discs, which wrap around the inner sidewall and end face of the gland.

[0009] In one optional embodiment, recessed grooves are provided at both ends of the shell, and the pressure cap is embedded in the recessed grooves at both ends of the shell, and the pressure cap abuts against the end face of the foam material filler to limit the displacement of the foam material filler in the axial direction of the shell.

[0010] In one optional embodiment, there are two chuck interfaces, corresponding to the inlet and outlet ends of the housing respectively. The lower sidewall of the chuck interface is in contact with the sealing disc of the rubber diaphragm, and the chuck interface is threadedly connected to the threaded hole of the housing by a fastening screw, so that the axial compressive force of the fastening screw acts on the sealing disc to achieve the sealing of the pipeline damper.

[0011] In one optional embodiment, the inner diameter of the gland is adapted to the tubular outer diameter of the rubber diaphragm, and the outer diameter of the gland is adapted to the inner diameter of the recessed groove on the housing.

[0012] In one optional embodiment, the sealing disc has an annular sealing protrusion on the side away from the tubular body of the rubber diaphragm, and the annular sealing protrusion fits tightly against the recessed part of the lower side wall of the chuck interface.

[0013] In one alternative embodiment, a sealing groove is provided above the chuck interface for connection with an external pipe, and the sealing groove is used to install a suitable sanitary pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Unlike traditional pipeline dampers that allow gas and flowing liquid to coexist in the same space, this device only allows the fluid to contact the chuck interface and rubber diaphragm, which can prevent the liquid and gas from reacting and consuming the gas, thus extending the service life of the equipment; it also prevents the liquid flowing through the damper from being mixed with impurities generated by the reaction with the gas.

[0016] 2. This utility model has a simple structure, few parts, and is easy to disassemble, which greatly reduces the difficulty of cleaning, meets the requirements for stable flow of different liquids, and reduces the installation and maintenance costs of the equipment.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0027] Please refer to Figures 1-5 The pipeline fluid damper includes a housing 1; it also includes a foamed material filler 5 installed inside the housing 1, a gland 3 installed on the housing 1, a rubber diaphragm 4 installed inside the foamed material filler 5, and a chuck interface 2 installed on the housing 1.

[0028] In a preferred embodiment of this utility model, the housing 1 serves as the core load-bearing component, providing an installation support frame for all internal components and ensuring the overall structural stability of the damper; the foamed material filler 5 is the core actuator for the damping function, which can dissipate the energy generated by fluid flow through its own deformation to achieve the damping effect; the pressure cap 3 is used to fix the position of the internal components and prevent the components from loosening; the chuck interface 2 and the sealing disc 402 on the rubber diaphragm 4 are pressed together by the fastening screws 6 to form a sealing structure, preventing fluid leakage.

[0029] In a preferred embodiment of this utility model, the rubber pipe 401 in the middle of the rubber diaphragm 4 is tubular and sleeved on the inner ring of the foamed material filler 5. The two ends of the rubber diaphragm 4 extend outward to form sealing discs 402. The sealing discs 402 wrap around the inner wall and end face of the pressure cap 3. The rubber pipe 401 in the middle of the rubber diaphragm 4 has a tubular structure, which can accurately fit the inner ring of the foamed material filler 5 to form a smooth fluid channel and ensure that the fluid passes through smoothly. The sealing discs 402 formed by the outward extension of its two ends wrap around the inner wall and end face of the pressure cap 3, greatly increasing the sealing contact area, blocking the fluid from leaking from the gap between the pressure cap 3 and the shell 1, and between the pressure cap 3 and the rubber diaphragm 4, and strengthening the sealing performance.

[0030] In a preferred embodiment of this utility model, recessed grooves 7 are provided at both ends of the housing 1, and the pressure cap 3 is embedded in the recessed grooves 7 at both ends of the housing 1. The pressure cap 3 abuts against the end face of the foamed material filler 5 to limit the displacement of the foamed material filler 5 in the axial direction of the housing 1. The recessed grooves 7 at both ends of the housing 1 provide precise installation positioning for the pressure cap 3, ensuring that the pressure cap 3 is quickly and accurately assembled. After the pressure cap 3 is embedded, it abuts against the end face of the foamed material filler 5, which can effectively limit the displacement of the foamed material filler 5 in the axial direction of the housing 1, avoid the foamed material filler 5 from moving due to factors such as fluid pressure and vibration, and ensure the stability of the damping effect.

[0031] In a preferred embodiment of this utility model, there are two chuck interfaces 2, corresponding to the inlet and outlet ends of the housing 1, respectively. The lower sidewall of the chuck interface 2 is in contact with the sealing disc 402 of the rubber diaphragm 4, and the chuck interface 2 is threadedly connected to the threaded hole 8 of the housing 1 by a fastening screw 6, so that the axial compressive force of the fastening screw 6 acts on the sealing disc 402 to achieve the sealing of the pipeline damper. The two chuck interfaces 2 correspond to the inlet and outlet ends of the housing 1, respectively, to achieve bidirectional connection between the damper and the external pipeline, ensuring normal fluid flow. The chuck interface 2 is threadedly connected to the housing 1 by a fastening screw 6. The axial compressive force generated when tightening acts on the sealing disc 402, so that the sealing disc 402 fits tightly against the lower sidewall of the chuck interface 2 and the pressure cap 3, which greatly improves the overall sealing performance and prevents fluid leakage.

[0032] In a preferred embodiment of this utility model, the inner diameter of the gland 3 is matched with the tubular outer diameter of the rubber pipe 401 of the rubber diaphragm 4, the outer diameter of the gland 3 is matched with the inner diameter of the recessed groove 7 opened on the housing 1, and the inner diameter of the gland 3 is matched with the tubular outer diameter of the rubber pipe 401 of the rubber diaphragm 4. This ensures that the fluid channel diameter is consistent, avoids turbulence caused by abrupt changes in channel size, and ensures smooth fluid flow. The outer diameter of the gland 3 is matched with the inner diameter of the recessed groove 7 of the housing 1, so that the gland 3 and the recessed groove 7 fit tightly together, preventing the gland 3 from wobbling radially, improving the overall structural stability, and indirectly ensuring the sealing and damping effect.

[0033] In a preferred embodiment of this utility model, an annular sealing protrusion is provided on the side of the sealing disc 402 away from the tubular body of the intermediate rubber pipe 401. The annular sealing protrusion fits tightly with the concave part of the lower side wall of the chuck interface 2. The annular sealing protrusion on the sealing disc 402 fits tightly with the concave part of the lower side wall of the chuck interface 2. The protrusion structure increases the pressure at the sealing contact point, which greatly improves the sealing reliability between the sealing disc 402 and the chuck interface 2. Especially for high-pressure fluid conditions, it can effectively prevent fluid penetration and leakage.

[0034] In a preferred embodiment of this utility model, a sealing groove for connecting to an external pipe is provided above the chuck interface 2. The sealing groove is used to install a suitable sanitary pad. When the chuck interface 2 is connected to the external pipe, the sanitary pad fills the gap between the two to form an "external seal". Together with the seal between the internal rubber diaphragm 4 and the sanitary chuck 2, it forms a sealing system that completely blocks fluid leakage from the connection between the damper and the external pipe.

[0035] During operation, the shell 1, the gland 3, and the rubber diaphragm 4 together form an internal enclosed space filled with foamed material filler 5. The foamed material filler 5 ensures that the elastic pipe composed of the rubber diaphragm 4 can expand and contract radially, while also preventing excessive expansion and contraction, thus maintaining the pipe structure. Fluid flows in through the chuck interface 2 at the inlet, enters the elastic pipe composed of the rubber diaphragm 4, and then flows out through the chuck interface 2 at the outlet. When the fluid flow rate in the pipe increases slightly, the elastic pipe composed of the rubber pipe 401 expands accordingly to absorb the extra small flow; when the fluid flow rate in the pipe decreases slightly, the rubber pipe 401 supported by the foamed material filler 5 rebounds accordingly, reducing the inner diameter of the pipe to bring the flow rate back to its original value.

[0036] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations will be apparent to those skilled in the art without actually departing from the scope and spirit of the claims, such as variations in the size, dimensions, structure, shape and proportion of the various elements, their installation arrangement, the materials used, their color, orientation, etc.

[0037] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
