Description
Technical field
The utility model is related to silencer field more particularly to a kind of New Ring-like Type silencers.
Background technology
Silencer is the dress that pneumatic noise in heating ventilation and air-conditioning system is reduced using principles such as absorption, reflection, the interference of sound
It puts.The characteristics of annular silencer is to belong to dissipative muffler, dissipative muffler dissipative muffler is made using the sound absorption of sound-absorbing material
With and eliminate the noise.It is that sound-absorbing material is fixed on the inner-walls of duct of air-flow flowing or is arranged in pipeline by certain way that it, which is constructed,
Or dissipative muffler is formed in housing, sound-absorbing material can sponge incident acoustic energy on it.Why acoustic energy can quilt
It absorbs, is the porosity and laxity due to sound-absorbing material.When sound wave enters hole, the air in hole and material is caused to generate
Small vibration due to friction and viscosity resistance, makes quite a few acoustic energy turn to thermal energy and be predominantly absorbed.Existing annular disappears
Sound device is preferable for high frequency and mid-frequency noise effect, but poor to low-frequency noise acoustic attenuation performance.
The content of the invention
The utility model aim is to provide a kind of New Ring-like Type silencer, adds the face that air-flow is contacted with inner-walls of duct
Product so that sound-absorbing material can absorb incident acoustic energy on it to a greater extent, reduces noise, so as to strengthen noise reduction effect
Fruit solves more than technical problem.
In order to realize above-mentioned technical purpose, reach above-mentioned technology requirement, technical solution is used by the utility model：
A kind of New Ring-like Type silencer, including shell, orifice plate is provided with mineral wool between the shell and orifice plate；The orifice plate
Inner cavity is provided with several identical cylindrical noise elimination rings, and the noise elimination ring includes outer orifice plate, inner hole plate, in outer orifice plate and interior
Mineral wool is provided between orifice plate, the noise elimination ring end face is provided with kuppe.
The shell, orifice plate, outer orifice plate, inner hole plate are made of galvanized steel plain sheet.
The shell, orifice plate, outer orifice plate, inner hole plate are made of aluminium alloy plate.
The shell, orifice plate, outer orifice plate, inner hole plate are made of stainless steel plate.
The exit orifice board keel of the noise elimination ring is close to orifice plate, is fixed using rivet.
The kuppe uses the splitter form of circular ring shape.
Connection mode between the annular silencer and miscellaneous equipment is arranged to flanged joint.
The beneficial effects of the utility model：A kind of New Ring-like Type silencer, compared with traditional structure：It is provided with several rule
The identical noise elimination ring of lattice, increases flow area, improves absorption, improve acoustic attenuation performance and aerodynamic quality；It eliminates the noise
Ring is provided with the kuppe of cylindrical splitter form, can more make air-flow smoothly by silencer, reduces the resistance of silencer
Loss, also allows for being connected with noise elimination ring；Noise elimination ring apertura lateralis board keel is close to silencer orifice plate inner wall, is fixed using rivet,
So that it can't see fixed point on entire noise elimination ring, it appears more beautiful.

Specific embodiment
In order to become apparent from the goal of the invention of the utility model, technical solution and its advantageous effects, with reference to
The utility model is further elaborated in the drawings and specific embodiments；
In the accompanying drawings：A kind of New Ring-like Type silencer, including shell 1, orifice plate 3 is set between the shell 1 and orifice plate 3
It is equipped with mineral wool 2；3 inner cavity of orifice plate is provided with several identical cylindrical noise elimination rings 4, and the noise elimination ring 4 includes
Outer orifice plate 6, inner hole plate 7 are provided with mineral wool 2 between outer orifice plate 6 and inner hole plate 7, and 4 end face of noise elimination ring, which is provided with, leads
Stream cover 5.
The shell 1, orifice plate 3, outer orifice plate 6, inner hole plate 7 are made of galvanized steel plain sheet；The shell 1, orifice plate 3,
Outer orifice plate 6, inner hole plate 7 are made of aluminium alloy plate；The shell 1, orifice plate 3, outer orifice plate 6, inner hole plate 7, using stainless steel
Plate makes；6 keel of outer orifice plate of the noise elimination ring 4 are close to 3 inner wall of orifice plate, are fixed using rivet；The kuppe 5 is adopted
With the splitter form of circular ring shape；The annular silencer, the connection mode between miscellaneous equipment are arranged to flanged joint.
When it is implemented, outer orifice plate, the inner hole plate of the utility model shell, orifice plate, noise elimination ring may be employed galvanized steel plain sheet,
The materials such as aluminium alloy plate, stainless steel plate make, and are flexibly selected according to engineering requirements.The deadener of the utility model is selected
Environmentally safe, the centrifugally glass-wool of free from extraneous odour, centrifugally glass-wool can select different unit weight, be typically chosen unit weight and be
The centrifugally glass-wool of 24kg/m3,32kg/m3,48kg/m3.The centrifugally glass-wool of different unit weights imitates the noise elimination of annular silencer
Fruit is influential, and the bigger noise elimination effect of unit weight is better.The utility model noise elimination ring uses the identical noise elimination ring of several specifications,
Its advantage is increased flow area, improves absorption, improves acoustic attenuation performance and aerodynamic quality；Noise elimination ring moulds block
Change, convenient for batch production, save cost；Reduce steel usage amount, alleviate silencer weight, be conducive to the transport of silencer
And installation, while reduce the reproduced air-flow noise and the pressure loss of silencer.Noise elimination ring makes noise elimination ring outer orifice plate dragon when installing
Bone is close to silencer orifice plate, is fixed using rivet, so that can't see fixed point on entire noise elimination ring, it appears more beautiful
It sees.
The kuppe of the noise elimination ring of the utility model can more make air-flow smoothly by disappearing using cylindrical splitter form
