The right side for stating barrier plate 5 is equipped with third flow cavity 9, and the bottom end of the outlet 10 through shell 1 and extends to third flow cavity 9
The inner cavity of inner cavity, the spring strut 7 is equipped with spring 16, and the bottom of the spring 16 is fixedly connected with transverse slat 15, the transverse slat 15
Bottom is fixedly connected with column cap 13, and the barrier plate 5 is equipped with cavity 17, and the bottom end of the column cap 13 is located at the inner cavity of cavity 17,
The fixed link 6 is equipped with four groups, and fixed link 6 described in four groups is circumferentially arranged using the axle center of spring strut 7 as the center of circle.
Wherein, the spring strut 7 is symmetrical is equipped with two groups, the coefficient of elasticity of left side 7 inner spring 16 of spring strut
Coefficient of elasticity than 7 inner spring 16 of right side spring strut is high, and the column cap 13 is set as trapezium structure, and the cavity 17 is by ladder
Shape cavity and rectangle cavity composition, and trapezoidal cavity is located at the top of rectangle cavity, first sound absorbing layer 12 and second is inhaled
Sound-absorbing layer 4 is made using glass fibre sound-absorbing material, it is characterised in that：First sound absorbing layer, 12 and second sound absorbing layer 4 with
Fixed plate 18 is fixedly connected, and the inner cavity of the cavity 17 is equipped with compatible wear-resistant pad therewith.
Operation principle：This muffler is equipped with air pressure control mechanism, when the refrigerant of high pressure enters the of shell 1 from import 2
When one flow cavity 3, the flowing space becomes larger so that refrigerant pressure reduces, and flowing velocity is slack-off, passes through the first sound absorbing layer 12 and the
The mutual cooperation of two sound absorbing layers 4 carries out first time noise reduction, when the air pressure in the first flow cavity 3 reaches certain value, this atmospheric pressure value
To be less than refrigerant not into the high-voltage value of institute's band when import 2, this air pressure makes the column cap 13 of 17 inner cavity of cavity on barrier plate 5 to the right
It is mobile, carry out compressed spring 16 so that the column cap 13 being tightly in contact with barrier plate 5 and gap is generated between barrier plate 5 originally,
So that refrigerant enters the second flow cavity 8 by gap so that the air pressure in the first flow cavity 3 reduces, when less than 16 bullet of spring
When power, spring 16 extends so that column cap 13 and the close contact of cavity 17 on barrier plate 5, are closed, due to the flowing space
It increases again so that the flowing velocity of refrigerant declines again, again passes by the first sound absorbing layer 12 and the second sound absorbing layer 4 is inhaled
Sound carries out second of sound-absorbing, and there are one atmospheric pressure values, this atmospheric pressure value to be less than the gas of the first flow cavity 3 in the second flow cavity 8 at this time
Pressure value, when the atmospheric pressure value in the second flow cavity 8 reaches a timing, this atmospheric pressure value is than the first flow cavity 3 so that column cap 13 moves
When atmospheric pressure value want small, again so that column cap 13 moves right so that the column cap 13 that is tightly in contact with barrier plate 5 and resistance originally
Gap is generated between baffle 5 so that the refrigerant in the second flow cavity 8 flow to third flow cavity 9, when atmospheric pressure value is less than spring
When 16 elastic force, column cap 13 can be closed automatically again, again due to the increase in space so that the flow velocity of refrigerant slows down again, leads to
It crosses the first sound absorbing layer 12 and the second sound absorbing layer 4 carries out third time sound-absorbing, then refrigerant is flowed out from outlet 10, in this process
In, for the first time so that column cap 13 does the own resilient of the spring 16 of open and close movement than for the second time so that column cap 13 does open and close movement
The own resilient of spring 16 is big, and in the whole process, the air pressure in the first flow cavity 3 is more than air pressure in the second flow cavity 8, the
Air pressure in two flow cavities 8 is more than the air pressure in third flow cavity 9, is equipped with vacuum layer 11, since refrigerant moves so that fixed
Plate 18 generates vibration, and then generates noise, since sound cannot be propagated in a vacuum so that noise is isolated, finally can be by
Sound absorbing layer consumes, and reinforcing prop 14 is equipped with, due to being equipped with vacuum layer 11 so that shell 1 is larger by the pressure of atmospheric pressure, leads to
14 reinforcement structure intensity of reinforcing prop is crossed, 3 flow cavities and two groups of air pressure control mechanisms are equipped with, by slowing down the flow velocity of refrigerant,
Also sound absorbing layer may make preferably to be purged to noise while enabling refrigerant to generate less noise during exercise, originally disappears
Sound device is simple in structure, good muffling effect, has very strong practical value.
