Housing cavity of the present utility model makes inner chamber be separated into several interval by the separation of upper and lower separating groove, when making its components be arranged on inner chamber, have and distribute preferably, the simultaneously filling of fiber also evenly, make waste gas in several interval, carry out several simultaneously and eliminate the noise and be conducive to raising erasure effect.And housing, waste gas air inlet and exhaust piper can be fixed on motor-vehicle chassis by pipeline grab and arranging of palette fork effectively all preferably, reduce vibrating noise during waste gas turnover.
Accompanying drawing explanation
Fig. 1 is the structural representation in the utility model embodiment;
Fig. 2 is the cross-sectional view of the utility model embodiment.
Embodiment
Do to illustrate in detail, intactly further to the utility model below in conjunction with mode of execution and accompanying drawing.
As shown in Figure 1-2, the utility model provides a kind of silencer for motor vehicle, comprise a housing 1, it has an inner chamber 11, described housing 1 is provided with in an import 12 and the shell construction of 2 outlets shown in 13, Fig. 1, also reserved 2 outlets 13, this reserved outlet 13 is in closed state certainly.Described import 12 and outlet 13 are for communication with cavity 11 and housing 1 outside, described import 12 is equipped with exhaust inlet pipe 2, described exhaust inlet pipe 2 extends in inner chamber 11 for waste gas being delivered into inner chamber 11 li, described outlet 13 is equipped with waste gas steam outlet pipe 3, described waste gas steam outlet pipe 3 extends out for being transferred out from inner chamber 11 by waste gas from inner chamber 11, an outer surface of described housing 1 is provided with several upper separating groove 14 from this inwardly chamber 11 protrusions, a face relative with this outer surface on described housing 1 is provided with several from lower separating groove 15 protruding and relative with upper separating groove 14 to inner chamber 11 this face, on described, lower separating groove 14, inner chamber 11 is separated into several space for filling noise reduction fiber by 15.
Preferably scheme, described housing 1 comprises upper shell 1a and lower shell body 1b, described upper shell 1a and lower shell body 1b fastens mutually rear formation inner chamber 11, described upper shell 1a and the mutual fastening part of lower shell body 1b are provided with the flange 16 extended to housing 11 outside, and described upper separating groove 14 and lower separating groove 15 are separately positioned on upper shell 1a and lower shell body 1b.
Preferably scheme, is equipped with stuffing box gland 4 between described import 12 and exhaust inlet pipe 2, is also equipped with stuffing box gland 4 between described outlet 13 and waste gas steam outlet pipe 3.Described stuffing box gland 4 is teflon seal cover.The operating temperature range of tetrafluoroethylene is about-269 DEG C to 270 DEG C, and its fusing point is 380 DEG C.Can stand the thermal peak of height to 330 DEG C, therefore this material can stand the high temperature of exhaust inlet pipe 2, and stops the heat transfer to shell 1.This outer seal sleeve 4 is flexible, can be out of shape with the distortion slightly adapted between import 12, outlet 13, exhaust inlet pipe 2 and waste gas steam outlet pipe 3, improve sealing effect.
Preferably scheme, described exhaust inlet pipe 2 is provided with the upper hook portion 51 of the pipeline grab 5 fitted with pipeline external surface, and the lower hook portion 52 of described pipeline grab 5 is arranged on connector 6, and described connector 6 is arranged on base 7.Described flange 16 is arranged with palette fork 8, and described palette fork 8 is provided with coupling shaft 81 and is arranged on connector 6, and described connector 6 is arranged on base 7.The upper hook portion 51 of pipeline grab 5 is contrary with the direction that institute's hook of lower hook portion 52 moves, and so makes pipeline grab 5 not easily vibrate when carrying waste gas under the pulling force effect of base 7 at connector 6.And housing 1 due to inner chamber 11 space larger, waste gas speed within it reduces greatly simultaneously, only need the weight of holding himself, make it have bearing capacity, 16 times housing 1 is held up so palette fork 8 is arranged on flange, because the volume of housing 1 is larger, so 2 need be arranged symmetrically in palette fork 8, and palette fork 8 is arranged near outlet pipe 3 and outlet 13, because gas is comparatively large from the perturbed force produced during this neighbouring outflow, so be arranged on the stability being conducive to housing 1 herein.
