Abstract
The utility model relates to gas space subset, a kind of oxygen nitrogen sound suppressor is provided, comprise cylindrical urceolus and inlet flange, it is characterized in that: described urceolus is provided with gas outlet, this gas outlet one end connects inlet flange, and the other end connects urceolus internal buffer, this buffer zone is short cylindric, cylindrical periphery is noise elimination filter net, and described outer tube inner wall is also provided with warming plate, and warming plate and buffer zone outer wall form packed layer.The utility model have employed a buffer zone at sound suppressor outer barrel, played the effect of noise emission again by noise elimination filter net, the sound wave dispersed enters fill area, implements secondary noise elimination process by noise elimination cotton and monofilament, noise is dropped to minimum, effectively realize soundproof effect; Moreover urceolus upper sealing plate is integral type, lower shrouding and orifice plate are detachable, while easy cleaning sound suppressor inside, for ensureing soundproof effect, between lower shrouding and orifice plate, being also provided with palm fibre pad, effectively ensureing acoustic attenuation performance, very have practical value.
Description
Technical field
The utility model relates to gas space subset, particularly a kind of sound suppressor.
Background technology
Old-fashioned gas space subset sound suppressor urceolus and noise elimination filter net entirely weld integral type, once blocking, cleans very difficult.Gas space subset sound suppressor comparatively advanced on the market at present, urceolus and wire gauze are bolted to connection, can disassembly, cleaning, and be provided with buffering warming plate, but simple warming plate still thoroughly cannot solve the problem that acoustic wave vibrations produces huge noise.In addition, if do not adopt also existence problem of full weldering integral type, be exactly that the upper and lower shrouding of sound suppressor urceolus is open owing to adopting, sound insulation is not in place, thus Muffler Performance is weakened greatly.
Summary of the invention
The purpose of this utility model is to provide a kind of oxygen nitrogen sound suppressor, to solve the problem of huge vibrations that prior art sonic impinging silencer internal wall causes and noise, up and down shrouding sound insulation deficiency.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of oxygen nitrogen sound suppressor, comprise cylindrical urceolus and inlet flange, it is characterized in that: described urceolus is provided with gas outlet, this gas outlet one end connects inlet flange, the other end connects urceolus internal buffer, and this buffer zone is short cylindric, and cylindrical periphery is noise elimination filter net, described outer tube inner wall is also provided with warming plate, and warming plate and buffer zone outer wall form packed layer.
Concrete, be provided with detachable orifice plate, lower shrouding bottom described urceolus, described orifice plate, lower shrouding are bolted.
Concrete, be provided with palm fibre pad between described orifice plate, lower shrouding.
As preferably, described packed layer packing material is noise elimination cotton, monofilament.
As preferably, described gas outlet stretches into buffer zone inner hub location.
As preferably, described packed layer volume is more than buffer zone twice.
The beneficial effects of the utility model are: the utility model have employed a buffer zone at sound suppressor outer barrel, the effect of noise emission is played again by noise elimination filter net, the sound wave dispersed enters fill area, secondary noise elimination process is implemented by noise elimination cotton and monofilament, noise is dropped to minimum, effectively realize soundproof effect; Moreover urceolus upper sealing plate is integral type, lower shrouding and orifice plate are detachable, while easy cleaning sound suppressor inside, for ensureing soundproof effect, between lower shrouding and orifice plate, being also provided with palm fibre pad, effectively ensureing acoustic attenuation performance, very have practical value.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: 1. urceolus; 2. inlet flange; 3. gas outlet; 4. buffer zone; 5. noise elimination filter net; 6. packed layer; 7. warming plate; 8. descend shrouding; 9. orifice plate; 10. bolt; 11. palm fibre pads.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
A kind of oxygen nitrogen sound suppressor, comprise cylindrical urceolus 1 and inlet flange 2, described urceolus 1 is provided with gas outlet 3, this gas outlet 3 one end connects inlet flange 2, the other end connects urceolus 1 internal buffer 4, and this buffer zone 4 is in short cylindric, and cylindrical periphery is noise elimination filter net 5, described urceolus 1 inwall is also provided with warming plate 7, and warming plate 7 and buffer zone 4 outer wall form packed layer 6.
Be provided with detachable orifice plate 9, lower shrouding 8 bottom described urceolus 1, described orifice plate 9, lower shrouding 8 are fixed by bolt 10.Palm fibre pad 11 is provided with between described orifice plate 9, lower shrouding 8.As preferably, described packed layer 6 packing material is noise elimination cotton, monofilament.Described gas outlet 3 stretches into buffer zone 4 inner hub location.Described packed layer 6 volume is more than buffer zone 4 twice.In the present embodiment, buffer zone 4 is positioned at the inner end on the upper side of urceolus 1, and buffer zone 4 is highly only urceolus 1 height about 1/5th, and also leaves with urceolus 1 inwall top the space being slightly less than buffer zone 4 height.
The present embodiment is the embodiment of the utility model example; for those skilled in the art; on the basis that the utility model discloses application process and principle; be easy to make various types of improvement or distortion; and the structure be not limited only to described by the above-mentioned embodiment of the utility model; therefore previously described mode is preferred version; and not there is restrictive meaning; every equivalence done according to the utility model changes and amendment, all in the scope protection domain of the utility model claims.
