The principle of use of the silencer is as follows: Figure 5 As shown, remove the locking block 5 from the positioning groove 11, align the test pipe on the top of the heat flow instrument with the corresponding positioning groove 11 and push it into it, install the locking block 5 and close the cover 2, and the assembly of the entire silencer cover is completed.

[0026] The utility model can be directly connected to the outside of the heat flow meter to eliminate the noise pollution generated by the operation of the heat flow meter, so that the test personnel are free from noise interference; on the other hand, the overall equipment structure is simple, the preparation cost is low and the practicality is high, which is more in line with current test needs.

[0027] Preferably, the sound-absorbing material 4 is a fabric sound-absorbing board. The fabric sound-absorbing board has excellent sound-absorbing performance, environmental protection characteristics, fire safety, and various decorative effects, and has diversified functions and better use effects.

[0028] In the present technical solution, the sound absorption cover body 1 includes a top panel 12, a first side panel 21, a second side panel 13 and a third side panel 14; the inner sides of the top panel 12, the first side panel 21, the second side panel 13 and the third side panel 14 are all paved with sound-absorbing material 4, and the sound-absorbing material 4 is paved on the inner wall of the entire accommodating space 3 to completely absorb the noise generated.

[0029] As a preferred Figure 3 As shown, the first side panel 21 and the third side panel 14 are both interlayer panels, that is, the first side panel 21 and the third side panel 14 each include an inner panel and an outer panel, and a circulation gap is provided between the inner panel and the outer panel; a plurality of first vents 15 are provided at one end of the outer wall of the first side panel 21 and the third side panel 14, that is, the outer panel is provided with the first vents 15; a plurality of second vents 16 are provided at the other end of the inner wall of the first side panel 21 and the third side panel 14 away from the first vents 15, that is, the inner panel is provided with the second vents 16; and the first vents 15 are connected to the second vents 16.
