Drawings
In order to illustrate the embodiments of the present invention or the technical solutions in the prior art more clearly, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is an enlarged schematic view of the utility model at a in fig. 1.
In the figure: 11-muffling pipe, 12-end cover, 13-air inlet pipe, 14-noise reduction plate, 15-fixing plate, 16-air outlet pipe, 17-sound insulation layer, 18-connecting seat, 19-gasket, 20-sliding rod, 21-buffer spring and 22-air hole.
Detailed Description
The utility model will now be described in detail with reference to fig. 1-2, wherein for ease of description the orientations described hereinafter are now defined as follows: the up, down, left, right, and front-back directions described below correspond to the up, down, left, right, and front-back directions in the projection relationship of fig. 1 itself.
The muffler for heating and ventilation equipment described in conjunction with fig. 1-2 comprises a muffler pipe 11, a plurality of noise reduction plates 14 are installed in the muffler pipe 11, a plurality of air holes 22 are formed in the noise reduction plates 14, connecting seats 18 are formed at two ends of the noise reduction plates 14, the connecting seats 18 are fixed on the muffler pipe 11, slide rods 20 are installed in the connecting seats 18, the slide rods 20 are connected with the noise reduction plates 14, buffer springs 21 are arranged between the noise reduction plates 14 and the connecting seats 18, and spacers 19 are arranged at two ends of the buffer springs 21, when air flow enters the muffler pipe 11, the air flow passes through the noise reduction plates 14 through the air holes 22, during the process, the air flow generates pressure on the noise reduction plates 14, so as to push the noise reduction plates 14 to slide along the slide rods 20, so that the buffer springs 21 deform, and further play a buffering role, because the noise reduction plates 14 can properly move in the connecting seats 18, the noise reduction plates 14 are matched with the buffer springs 21 to buffer the noise reduction plates 14, thereby weakening the damage of the long-term airflow impact on the joint of the noise reduction plate 14 and the muffler pipe 11.
The noise reduction plate 14 is made of glass wool, so that a plurality of small holes are formed in the noise reduction plate 14, and when air flow passes through the noise reduction plate 14, sound energy is rubbed in the small holes and converted into heat energy to be dissipated, so that a noise reduction effect is achieved.
The two ends of the silencing pipe 11 are provided with end covers 12, the end covers 12 are provided with threads, the two ends of the silencing pipe 11 are provided with internal threads matched with the internal threads, the silencing pipe 11 and the end covers 12 can be tightly matched, and the two end covers 12 are respectively provided with an air inlet pipe 13 and an air outlet pipe 16.
