Description

Technical Field

[0001] The present invention relates to the technical fields of valves and shock absorption and noise reduction, and in particular to a valve with a double-layer honeycomb structure outlet. Background Art

[0002] As an essential control element in life, valves play a crucial role in fluid transportation systems such as water, gas, and oil. By regulating flow rate, pressure, and direction, they ensure the efficiency and stability of residential safety, industrial production, and urban operation. However, during the operation of valves, vibration and noise are inevitable phenomena, and their frequency range may extend from zero hertz to infinity.

[0003] The main reasons for valve noise can be attributed to mechanical vibration and fluid dynamics. Mechanical vibration usually stems from insufficient machining and assembly accuracy of internal parts of the valve or wear, especially when the external excitation frequency matches the natural frequency of the valve, resonance will occur, leading to severe vibration and noise. Fluid dynamics involves shock waves and vortex shedding caused by the sharp changes in flow velocity and pressure when gas or liquid passes through the throttling part of the valve. Under the conditions of high liquid flow velocity and large pressure difference, flashing and cavitation are more likely to occur, resulting in the rupture of bubbles and the generation of high-frequency noise.

[0004] Valves in a vibration environment for a long time will accelerate their wear and shorten their service life. At the same time, noise, especially low-frequency noise, due to its strong penetration and difficult attenuation characteristics, will also cause damage to human hearing when exposed to a strong noise environment for a long time. Therefore, it is particularly important to take measures to reduce vibration and noise for valves. Summary of the Invention

[0005] The purpose of the present invention is to provide a valve with a double-layer honeycomb structure outlet, which can effectively reduce noise by dynamically adjusting the porosity and fluid flow direction to control fluid dynamics characteristics.

[0006] To achieve the above purpose, the present invention provides a valve with a double-layer honeycomb structure outlet, including a main valve. A handwheel switch is arranged above the main valve. Both ends of the main valve are connected with valve ports. A valve cavity is arranged between the valve ports and the main valve. Double-layer honeycomb structures are arranged on the valve ports, and a rotating mechanism is arranged outside the valve cavity corresponding to the double-layer honeycomb structures.

[0007] Preferably, the double-layer honeycomb structure includes a double-layer parallel honeycomb structure, a double-layer deflected honeycomb structure, and other honeycomb-like perforated discs.

[0008] Preferably, the double-layer honeycomb structure includes a honeycomb structure fixed layer, the honeycomb structure fixed layer is arranged at the valve port, a honeycomb structure movable layer is arranged in the valve cavity on the side of the honeycomb structure fixed layer close to the main valve, and the honeycomb structure movable layer is connected to the rotating mechanism.

[0009] Preferably, the honeycomb structure fixed layer and the honeycomb structure active layer are both composed of honeycomb discs, and flat honeycomb holes are evenly distributed on the honeycomb discs.

[0010] Preferably, the driving modes of the rotating mechanism include manual, electric, pneumatic and hydraulic driving.

[0011] Therefore, the present invention adopts a valve with a double-layer honeycomb structure outlet as described above, which has the following beneficial effects compared with the prior art:

[0012] 1. The present invention can effectively break the low-frequency eddy structure generated by the fluid passing through the valve by arranging a honeycomb plate at the valve outlet, thereby reducing the noise caused by the eddy current. This structural design helps to destroy the fluid dynamics mode that may cause noise by increasing the disturbance of the fluid;

[0013] 2. The introduction of the rotating mechanism enables the valve to dynamically adjust the porosity of the honeycomb structure and the fluid flow direction according to the flow conditions and noise control requirements, providing flexible flow and noise control. By reducing the energy loss of the fluid when passing through the valve, the present invention helps to improve the energy efficiency of the fluid delivery system, especially in the system where the fluid flow needs to be precisely controlled;

[0014] 3. The design of the honeycomb panel is simple and sophisticated, easy to manufacture and install. This design allows for quick installation and replacement of the honeycomb panel, reduces maintenance time and cost, and reduces noise pollution, helps improve the working environment, reduces the impact on the surrounding community, and meets the requirements of environmental protection and sustainable development.

[0024] Embodiment

[0025] As Figure 1 shown, a valve with a double-layer honeycomb structure outlet of the present invention includes a main body valve 1, a handwheel switch 2 is arranged above the main body valve 1, valve orifices 3 are connected to both ends of the main body valve 1, a valve cavity 4 is arranged between the valve orifice 3 and the main body valve 1, a double-layer honeycomb structure 5 is arranged on the valve orifice 3, and a rotating mechanism 6 is arranged outside the valve cavity 4 corresponding to the double-layer honeycomb structure 5.

[0026] The double-layer honeycomb structure 5 includes a double-layer parallel honeycomb structure, a double-layer deflection honeycomb structure and other honeycomb-shaped perforated discs.

[0027] The double-layer honeycomb structure 5 includes a honeycomb structure fixed layer, the honeycomb structure fixed layer is arranged on the valve orifice 3, a honeycomb structure movable layer is arranged in the valve cavity 4 on the side of the honeycomb structure fixed layer close to the main body valve 1, and the honeycomb structure movable layer is connected to the rotating mechanism 6.

[0028] Both the honeycomb structure fixed layer and the honeycomb structure movable layer are composed of honeycomb discs, and flat honeycomb holes are uniformly distributed on the honeycomb discs.

[0029] The driving modes of the rotating mechanism 6 include manual, electric, pneumatic and hydraulic driving.

[0030] In the specific implementation process, the double-layer honeycomb structure 5 of the valve is the core of the present invention. It is composed of a honeycomb structure fixed layer 51 and a honeycomb structure movable layer 52. Each layer is composed of flat honeycomb holes evenly distributed. This design can not only ensure the uniformity of mass distribution but also expand the change range of porosity during rotation. There are various replaceable types of honeycomb structure designs, including a double-layer parallel honeycomb structure for adjusting porosity, a double-layer deflected honeycomb structure for adjusting the flow direction, and other honeycomb-like punched discs to adapt to different fluid control requirements. The size of the honeycomb structure needs to be customized according to the diameter of the valve port 4 to achieve complete coverage and optimize fluid interaction. The thickness of the honeycomb disc needs to be precisely controlled so that it can not only ensure sufficient structural strength but also maintain lightweight characteristics.

[0031] The honeycomb discs of the honeycomb structure fixed layer 51 are fixed and provide a stable reference for the valve, ensuring the stability and reliability of the structure. In contrast, the honeycomb discs of the honeycomb structure movable layer 52 are connected by a rotating mechanism 6. The rotating mechanism 6 supports manual, electric, pneumatic, or hydraulic drive, enabling the honeycomb structure movable layer 52 to perform precise rotational adjustment to adapt to different fluid conditions and noise control requirements. When the valve adjusts the flow rate, the changes in the valve opening and flow rate will cause changes in the size and structure of the eddy currents inside the valve, thereby affecting the hydrodynamic characteristics and noise level.

[0032] The double-layer honeycomb structure 5 design of the present invention can flexibly adapt to these changes, such as Figures 2 - 3 shown. When the double-layer parallel honeycomb structure is adopted, the honeycomb structure movable layer 52 rotates to a specific angle through the activation of the rotating mechanism 6, achieving misalignment with the honeycomb structure of the honeycomb structure fixed layer 51. This misaligned state causes some honeycomb holes to be covered, thereby dynamically changing the porosity of the honeycomb plate. The change in porosity directly affects the flow characteristics of the fluid passing through the valve, including flow velocity, flow direction, and the formation of eddy currents, thereby effectively controlling hydrodynamic noise;

[0033] such as Figure 4 shown. When the double-layer deflected honeycomb structure is adopted, the rotation of the honeycomb structure movable layer 52 can adjust the fluid flow direction, enabling the fluid to not only effectively break the vortex structure during the flow deflection process but also dissipate most of the energy, thereby reducing noise while significantly reducing the impact of the fluid on the downstream pipe wall, thus extending the service life of the valve.

[0034] In addition, when it is necessary to finely adjust the porosity and the fluid flow direction simultaneously, two honeycomb structures can be installed in parallel. In addition to the honeycomb structure, the present invention also provides other honeycomb-like discs as options, such as Figure 5As shown, the process of punching these discs is simple and suitable for occasions with low precision requirements and not strict mechanical property requirements. It can also achieve an effect similar to that of the honeycomb structure, providing a flexible choice for different application scenarios.

[0035] Therefore, the present invention adopts a valve with a double-layer honeycomb structure outlet as described above. By dynamically adjusting the porosity and the fluid flow direction, it can break the low-frequency vortex structure under different fluid conditions and achieve the best noise suppression effect. This design not only improves the service life of the valve but also reduces the impact on the surrounding environment. This innovative design provides a new direction for the valve noise reduction technology and solves the problems of the existing technology.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.
