Please refer to fig. 1 to 3:

the utility model provides a noise-reducing and silencing heating and ventilation pipeline, which comprises a main pipeline 1 and a U-shaped pipe 2, wherein the U-shaped pipe 2 is welded at the top of the main pipeline 1, a rubber layer 5 is adhered to the inner circumferential surface of the main pipeline 1, a plurality of silencing holes 501 for silencing are uniformly formed in the inner circumferential surface of the rubber layer 5, a filter screen 6 is adhered to the inner circumferential surface of the rubber layer 5, an air release pipe 7 is inserted into the top of the U-shaped pipe 2, a water tank 9 is welded on the right side surface of the U-shaped pipe 2, a miniature high-pressure water pump 10 is installed on the right side surface of the water tank 9, sound-absorbing cotton 3 is adhered to the outer circumferential surface of the main pipeline 1, and tinfoil 4 is adhered to the outer circumferential surface of the sound-absorbing cotton 3;

specifically, by arranging the rubber layer 5 on the inner wall of the main pipe 1, when solid impurities flow in the main pipe 1, the solid impurities only collide with the rubber layer 5 and cannot directly contact with the inner wall of the main pipe 1, so that noise can be well reduced, and the silencing hole 501 is formed in the rubber layer 5, if noise is generated, the number of times of noise reflection can be increased by the silencing hole 501, so that the noise repeatedly collides with the rubber layer 5, and silencing and noise reduction are performed, and by arranging the filter screen 6 on the rubber layer 5, the solid impurities can be prevented from entering the silencing hole 501 and blocking the silencing hole 501;

the sound-absorbing cotton 3 is arranged on the outer wall of the main pipeline 1, so that the noise can be reduced outside the main pipeline 1, the noise reduction effect of the main pipeline 1 can be further improved, and the main pipeline 1 can be insulated through the matching of the sound-absorbing cotton 3 and the tinfoil 4, so that the heat loss of heating water is reduced;
