The external strengthening silencer of this baffler is under the condition of structure that does not change baffler inside, by the first grip block, the slab construction of the second grip block and on the first fixed hole, the second fixed hole coordinates the first clamping cylinder, the second clamping cylinder is installed on hush pipe outer wall, the baffler outer wall of fitting between noise reduction layer natural imbedding clamping cylinder and baffler outer wall, quieter material in the noise reduction layer embedding can improve baffler erasure effect on the basis of original baffler, provide a kind of effective for the not good problem of noise reduction in baffler using process, solution easily.Wherein, described the first clamping plate, the second clamping plate external frame are near the resistance of air that is shaped as fusiform profile and is the silencer that reduces to install additional of one end of hush pipe suction port, thereby the surface area that is provided with staggered spiracle on noise reduction layer and has increased noise reduction layer has strengthened erasure effect, also strengthened the effect of heat radiation simultaneously.
Further, the quantity of described the first fixed hole, the second fixed hole is 2.After relying on internal thread, nut to tighten by corresponding fixed hole, the first semicircular cylinder ring, the second semicircular cylinder ring are fixed on baffler outer wall and with outer wall close contact, 2 fixed holes are preferred fixed hole quantity.
Further, the material of described noise reduction layer is the composite material that low frequency damping soundproof material and fire-retardant crest acoustical cotton hot pressing form.This material is preferred quieter material, for the prior art products of Yin Chuan company, normally formed by the thick low frequency damping soundproof material of one deck 2mm and the thick fire-retardant crest acoustical cotton hot pressing of one deck 25mm, excellent noise reduction effect, lightweight, fire-retardant characteristic has been avoided danger on fire, also has certain damping effect simultaneously.
Further, the diameter range of described spiracle is 3mm-8mm, and the scope at the interval of arranging between adjacent spiracle is between 20mm-50mm.Aperture is less in theory, and perforate is more, and getable noise reduction surface area is larger, if but perforate cross at most stability of material and decline, the size of above-mentioned spiracle and interval are preferred size, for the stability that obtains erasure effect preferably and take into account perforate.
To sum up, the beneficial effects of the utility model are:
The external strengthening silencer of this baffler is under the condition of structure that does not change baffler inside, by grip block, noise reduction layer is installed on hush pipe outer wall, can on the basis of original baffler, improve baffler erasure effect, for the not good problem of noise reduction in baffler using process provide a kind of effectively, solution easily.
