Abstract
The invention discloses a kind of hose assemblies with silencing function, including first flange, second flange, metal hose, steel pipe, sound-proof material and iron sheet, the steel pipe is open at one end, formula structure closed at one end, it is mutually welded with first flange the open end of steel pipe, metal hose is sheathed on steel pipe, and one end of metal hose is mutually welded with first flange, the other end is mutually welded with second flange, steel pipe closed end is placed in the inside of second flange, sound-proof material is wrapped on metal hose, and iron sheet is wrapped on sound-proof material.The present invention effectively reduces the pneumatic noise in hose assembly from metal hose to external radiation, reduces the propagation of noisiness.
Description
Technical field:
The present invention relates to a kind of hose assemblies with silencing function.
Background technique:
Currently, when high-speed centrifugal fan cabinet and exhaust pipe are attached, in order to compensate for asking for pipeline center's offset
Topic, mostly use common hose assembly (or flexible joint), existing hose assembly when in use, hose assembly one end
Installation is connected on blower cabinet, and other end installation is connected on exhaust pipe, and the metal hose in hose assembly is compensation wind
The key point that the outlet of machine cabinet is misaligned with exhaust pipe.The air-flow of volute of blower discharge is along flowing to exhaust pipe, air-flow
Speed mostly in 30m/s or so, which causes very big noise direct through metal hose by unidirectional sheet steel pipe with pipe friction
To external radiation, the physical and mental health of operating personnel is seriously affected.
Summary of the invention:
The present invention is to provide a kind of hose assembly with silencing function to solve the above-mentioned problems of the prior art.
The technical solution adopted in the present invention has: a kind of hose assembly with silencing function, including first flange, the second method
Orchid, metal hose, steel pipe, sound-proof material and iron sheet, the steel pipe are open at one end, formula structure closed at one end, the open end of steel pipe
It is mutually welded with first flange, metal hose is sheathed on steel pipe, and one end of metal hose is mutually welded with first flange, the other end
It is mutually welded with second flange, steel pipe closed end is placed in the inside of second flange, and sound-proof material is wrapped on metal hose, iron sheet package
In on sound-proof material.
Further, the outside bending in the both ends of the iron sheet and the planar side that is fixedly connected is formed, iron sheet both ends
Side is fixedly connected with to be anchored in first flange and second flange by the way that bolt is corresponding.
Further, the sound-proof material is pasted on the outer wall of metal hose by adhesive.
Further, the thickness of the sound-proof material is greater than 30mm.
Further, the thickness of the iron sheet is greater than 0.5mm.
Further, arrow mark is sprayed on the outer wall of the iron sheet, the arrow of arrow mark is directed toward the closed end of steel pipe.
The invention has the following beneficial effects: the present invention to effectively reduce the pneumatic noise in hose assembly by metal hose
To external radiation, the noise transmission of hose assembly is reduced.
Detailed description of the invention:
Fig. 1 is structure of the invention figure.
Fig. 2 is partial enlarged view of the present invention.
Specific embodiment:
The present invention will be further described below with reference to the drawings.
Such as Fig. 1 and Fig. 2, a kind of hose assembly with silencing function of the present invention, including first flange 21, second flange 22,
Metal hose 3, steel pipe 4, sound-proof material 11 and iron sheet 12, steel pipe 4 are open at one end, formula structure closed at one end, the open end of steel pipe 4
It is welded with 21 phase of first flange, the closed end of steel pipe 4 is hanging, and metal hose 3 is sheathed on steel pipe 4, and one end of metal hose 3
It is welded with 21 phase of first flange, the other end is welded with 22 phase of second flange.4 closed end of steel pipe is placed in the inside of second flange 22,
Sound-proof material 11 is wrapped on metal hose 3, and iron sheet 12 is wrapped on sound-proof material 11.
For being fixedly connected convenient for iron sheet 12 and flange, the outside bending in the both ends of iron sheet 12 simultaneously forms planar fixation
Side 121 is connected, the side 121 that is fixedly connected at 12 both ends of iron sheet is anchored on first flange 21 and second flange 22 by bolt correspondence
On.
Sound-proof material 11 is pasted on the outer wall of metal hose 3 by adhesive.The thickness of sound-proof material 11 is greater than 30mm, iron sheet
12 thickness is greater than 0.5mm.
Arrow mark 5 is sprayed on the outer wall of iron sheet 12, the arrow of arrow mark 5 is directed toward the closed end of steel pipe 4.Arrow mark
5 can reduce hose assembly installation direction mistake.
When in use, first flange 21 is connected on blower cabinet hose assembly, and second flange 22 is connected to exhaust pipe
On, sound-proof material 11 and iron sheet 12 effectively reduce the pneumatic noise in hose assembly from metal hose to external radiation, reduce soft
The noise transmission of pipe assembly.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as of the invention
Protection scope.
