Description

Technical Field

[0001] The utility model relates to the field of water pipe sound insulation, and specifically relates to a sound insulation pipe device. Background Art

[0002] In the fields of industrial pipelines, exhaust pipes, compressed air systems, turbochargers, hydraulic equipment, etc. It can effectively reduce the gas flow noise and improve the operating efficiency of the system. The current noise control methods for sound insulation pipes mainly include measures such as increasing the pipe thickness, using shock-absorbing brackets, installing sound insulation boards, etc., but these methods often have disadvantages such as high cost, complex construction, and limited effects. Content of the Utility Model

[0003] In order to overcome the above deficiencies, the utility model provides a sound insulation pipe device.

[0004] The technical solution adopted by the utility model:

[0005] A sound insulation pipe device includes a water pipe. Six rock wool strips are fixed on the outer wall of the water pipe. The six rock wool strips are evenly distributed around the outer wall of the water pipe at equal intervals. The rock wool strips extend along the axial direction of the water pipe. The outer wall of the rock wool strip is coated with fiberglass cloth, and the outer wall of the fiberglass cloth is coated with a galvanized layer.

[0006] The beneficial effects of the utility model:

[0007] Through the combined design of the three-layer structure, especially the inner rock wool strips, the utility model realizes the efficient absorption and attenuation of the sound inside and outside the water pipe, greatly reduces the transmission of noise, and improves the comfort of the living or working environment. The addition of fiberglass cloth and galvanized layer not only enhances the overall structural strength of the sound insulation pipe device, but also provides good anti-corrosion and rust-proof protection, extends the service life of the equipment, and reduces the cost of maintenance and replacement.

[0012] Such as Figures 1-3Shown: A silencing pipe device, including a water pipe 1. Six rock wool strips 2 are fixed on the outer wall of the water pipe 1. The six rock wool strips 2 are evenly distributed around the outer wall of the water pipe 1 at equal intervals. The rock wool strips 2 extend along the axial direction of the water pipe 1. The outer wall of the rock wool strips 2 is coated with fiberglass cloth 3, and the outer wall of the fiberglass cloth 3 is coated with a galvanized layer 4.

[0013] As an efficient sound-absorbing material, the internal porous structure of rock wool can effectively absorb and consume sound wave energy, reducing the reflection and propagation of sound waves on the outer wall of the water pipe. The rock wool strips 2 are evenly distributed around the water pipe 1 at equal angles, ensuring that the sound in all directions can be effectively attenuated.

[0014] The fiberglass cloth 3 not only provides additional physical strength, enhancing the structural stability of the entire silencing pipe device, but also plays a role in isolating the external environment, preventing impurities such as water vapor and dust from penetrating into the rock wool layer and affecting the sound-absorbing effect. At the same time, the fiberglass cloth 3 also has a certain damping effect, which can further weaken the propagation of sound waves.

[0015] The galvanized layer 4 covers the outside of the fiberglass cloth 3, mainly playing the roles of anti-corrosion, rust prevention, and beautification. It can not only protect the internal rock wool and fiberglass cloth from the influence of the external harsh environment and extend the service life of the silencing pipe device, but also further reduce the propagation of sound waves through the reflection characteristics of its metal surface, especially in the high-frequency band.
