Abstract
The utility model discloses a muffler which comprises a shell (3), an upper end cover (2), a lower end cover (7), an air outlet pipe (1) and an air inlet bend pipe (8). The muffler is characterized in that the part close to the lower end cover, in the shell is internally provided with a first perforated clapboard (6); alkali-free glass fiber cotton is filled between the first perforated clapboard and the lower end cover; a second perforated clapboard (5) which is parallel to and is fixed on the first perforated clapboard is arranged at the part close to the middle part of the shell; an outer shell of a muffling chamber (4) is sleeved on the air outlet end of the air inlet pipe; a section of outer surface in the muffling chamber of the air outlet end of the air inlet pipe is provided with a plurality of small holes; the outer shell of the muffling chamber is filled with the alkali-free glass fiber cotton; the air outlet pipe is fixed on the shell, and one end of the air outlet pipe positioned in the shell is sealed; and the outer surface of the air outlet pipe in the shell is provided with a plurality of small holes. The muffler provided by the utility model has an obvious muffling effect, has less power loss, and has superior performances.
Description
Technical field
The utility model relates to a kind of engine fittings, relates in particular to a kind of silencing apparatus.
Background technique
As everyone knows, silencing apparatus is an important accessory on the motor, if mate improperly, or the noise elimination effect is undesirable, or because resistance is too big, the power of motor is brought seriously influence.
The model utility content
The purpose of the utility model is for the deficiency that overcomes existing technology a kind of silencing apparatus effective, that engine power loss is less of eliminating the noise to be provided; Its concrete technological scheme is: silencing apparatus comprises housing, upper end cap, lower end cap, steam outlet pipe, intake elbow; Lean on the lower end cap place to be provided with the first porose dividing plate in the housing, be filled with the alkali-free glass fiber cotton between the first porose dividing plate and the lower end cap, there is one second porose dividing plate at nearly middle part with the first porose dividing plate secured in parallel in the housing; One anechoic room outer cover suit is in the outlet side of suction tude; One section outer surface in the anechoic room of suction tude outlet side is provided with countless apertures, is filled with the alkali-free glass fiber cotton in the anechoic room shell, and steam outlet pipe is fixed on the housing; It is positioned at the end sealing of housing, and the outer surface that steam outlet pipe is positioned at housing is provided with countless apertures.
Aperture area summation on the outer surface of said suction tude outlet side should be greater than the section area of the suction tude mouth of pipe.
Aperture area summation on the said steam outlet pipe outer surface should be greater than steam outlet pipe mouth of pipe section area.
Can find out from the technological scheme of the utility model; Because using porose dividing plate is three chambeies with the silencing apparatus volume separation; Played buffering, stable and eliminate the effect of basic, normal, high audio-frequency noise respectively, be filled with the alkali-free glass fiber cotton between anechoic room cavity and the first porose dividing plate and the lower end in addition and played acoustically effective, thereby the noise elimination effect is more obvious; And power loss is less, and performance is more superior.Reached the goal of the invention of the utility model fully.
Description of drawings
Fig. 1 is the structural representation of the utility model silencing apparatus.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to detail.
Embodiment 1, and referring to accompanying drawing 1, silencing apparatus comprises housing 3, upper end cap 2, lower end cap 7, steam outlet pipe 1, intake elbow 8; Lean on the lower end cap place to be provided with between first porose dividing plate 6, the first porose dividing plates and the lower end cap in the housing and be filled with the alkali-free glass fiber cotton, there is one second porose dividing plate 5 at nearly middle part with the first porose dividing plate secured in parallel in the housing; One anechoic room, 4 outer cover suits are in the outlet side of suction tude; One section outer surface in the anechoic room of suction tude outlet side is provided with countless apertures, is filled with the alkali-free glass fiber cotton in the anechoic room shell, and steam outlet pipe is fixed on the housing; It is positioned at the end sealing of housing, and the outer surface that steam outlet pipe is positioned at housing is provided with countless apertures.Aperture area summation on the outer surface of said suction tude outlet side should be greater than the section area of the suction tude mouth of pipe.Aperture area summation on the said steam outlet pipe outer surface should be greater than steam outlet pipe mouth of pipe section area.
