The water pipe vibration damping and noise reducing apparatus comprises an outer casing which is arranged on the outer wall of the water pipe, and a vertical damping component, a horizontal damping component, a pressure damping component, a vibration absorbing component and a connecting flange which are arranged between the outer casing and the outer wall of the water pipe; the vertical damping component is arranged in the direction vertical to a water pipe axis and connected with the connecting flange; the horizontal damping component is arranged in the direction paralleled to the water pipe axis and connected with the flange; the structure of the water pipe vibration damping and noise reducing apparatus of the utility model is simple, the installation is convenient, the effects of the vibration damping and noise reducing are outstanding, and the service life is long.
Description
Technical field
The utility model relates to the vibration and noise reducing device, relates in particular to a kind of water pipe vibration and noise reducing device.
Background technique
In the supply channel,, and therefore form noise because the variation of pump operation and water flow etc. often cause the water pipe vibration.The water pipe vibration can cause its structure and annex to produce fatigue ruption, even causes that water pipe breaks, and causes the waste of water resources, and brings unknown losses.And vibration causes that the low-frequency noise that solid-borne sound transmission produces endangers also very serious to human body.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of vibration and noise reducing device that is used for water pipe is provided.
The technological scheme that realizes above purpose is:
A kind of water pipe vibration and noise reducing device is characterized in that: comprise the shell that is arranged on the pipe outer wall, and be arranged at vertical attenuation part, horizontal attenuation part, pressure attenuation part, vibration absorption component and adpting flange between shell and pipe outer wall; Described vertical attenuation part be arranged at water pipe axle Vertical direction on and be connected with described adpting flange; Described horizontal attenuation part be arranged at water pipe axle parallel direction on and be connected with described adpting flange.
In a kind of optimized technical scheme, described pressure attenuation part is two-step throttle labyrinth pipe.
Vertical attenuation part can be made by the elastic material of Hooke coefficient k＞6 such as rubber etc. in the utility model.
Horizontal attenuation part can be made by the elastic material of Hooke coefficient k＞8 such as rubber etc. in the utility model.
Vibration absorption component is made by sound-absorbing porous material in the utility model.
Water pipe vibration and noise reducing device of the present utility model is simple in structure, easy for installation, effect of vibration and noise reduction excellence, long service life.
Description of drawings
Fig. 1 is according to the sectional view of the water pipe vibration and noise reducing device of the utility model preferred embodiment, has only represented the side that water pipe is axial among the figure.
Embodiment
With reference to figure 1, a kind of water pipe vibration and noise reducing device comprises vertical attenuation part 1, horizontal attenuation part 2, pressure attenuation part 3, vibration absorption component 4, shell 5 and adpting flange 6.Shell 5 is socketed on the water pipe 7, an end and water pipe welding, and the other end is unsettled.Vertical attenuation part 1, horizontal attenuation part 2, pressure attenuation part 3, vibration absorption component 4 and adpting flange 6 all are arranged between outer casing inner wall and the pipe outer wall.Vertical attenuation part 1 is connected with adpting flange 6, and vertical with the water pipe axle.Horizontal attenuation part 2 is connected with another adpting flange 6, and parallel with the water pipe axle.Pressure attenuation part 3 is two-step throttle labyrinth pipe.Vibration absorption component 4 is embedded between the inwall of vertical attenuation part 1, horizontal attenuation part 2 and shell 5.
Claims (2)
1. water pipe vibration and noise reducing device is characterized in that: comprise the shell that is arranged on the pipe outer wall, and be arranged at vertical attenuation part, horizontal attenuation part, pressure attenuation part, vibration absorption component and adpting flange between shell and pipe outer wall; Described vertical attenuation part be arranged at water pipe axle Vertical direction on and be connected with described adpting flange; Described horizontal attenuation part be arranged at water pipe axle parallel direction on and be connected with described adpting flange.
