Abstract
The utility model relates to a new silencer, which belongs to fittings of refrigerating systems used for air conditioners. The utility model comprises a pipe body, wherein, pipe mouths of both ends of the pipe body are made into shrunk mouths; the shrunk mouth positions of both ends are arranged at axial leads of the shrunk mouths deviating from the axial lead of the pipe body, one shrunk mouth is arranged in the right and the other shrunk mouth is arranged in the left. The wall thickness of each part of the shrunk mouths can be maintained to be uniform. The silencer can increase the vibration damping and noise reduction effect of the refrigerating systems of the air-air conditioners, and can be suitable for use in various refrigerating systems of the air conditioners.
Description
It is vibration-absorbing and silencing device in the idle call refrigeration system of working medium with the cold-producing medium that the utility model relates to a kind of, belongs to the spare and accessory parts of operation of air conditioning systems.
Being used at present with the cold-producing medium is the vibration-absorbing and silencing device of air-conditioning refrigeration system of working medium, adopt to be the concentric reducing of integral type copper tube or the mouth that is about to the copper tube two ends shorten into the symmetry of the central point of copper tube central axis mouthful with necking down process, though can eliminate air-conditioner refrigerating system flowing and partial noise and vibration that the vibration of press causes in the application because of cold-producing medium, but because the refrigeration system internal pressure is very big, particularly floride-free refrigeration system pressure is bigger, so this silencer is still undesirable.
The purpose of this utility model provides a kind of effect of vibration and noise reduction that can further improve air-conditioning refrigeration system.Make refrigeration system more be applicable to the model muffler of the floride-free refrigeration system of environment-friendly type.
For achieving the above object, the utility model is taked following design: the mouth of pipe at model muffler body two ends is made reducing, the axial line that the position of two ends reducing is located at this reducing departs from the body axial line, about each one, and keep each position wall thickness of reducing even.
Rotate the noise that the vibration that causes and the pressure fluctuation of working medium in pipeline cause at a high speed owing to having adopted above-mentioned technical scheme to make from compressor, owing to the structure of model muffler decentraction has increased vector moment, thereby increased the vibratory response that vibration damping has reduced pipe-line system, model muffler not only has the good medium and low frequency noise reduction characteristic of reactive muffler in addition, and effective length of flow that its asymmetric design has increased silencer is of value to noise reduction, working medium local flow speed is advanced because of model muffler simultaneously, outlet disalignment and changing, increased flow resistance, thereby play the effect of noise elimination, model muffler is well suited for various air-conditioning refrigeration systems and uses, be more suitable for floride-free refrigeration system of environment-friendly type and frequency changing refrigeration system and use, good economic benefits and social benefit are arranged.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model
Among the figure: 1 body, 2 reducings, 1,3 reducings 2,
Figure middle tube body 1 selects for use the copper tube that meets GB to make, and overall diameter is 30mm-60mm, and length is 200mm-300mm.The mouth of pipe at body two ends is made reducing 1, reducing 2, its size is pressed the specifications and models design of air conditioner and is decided, the internal diameter of reducing 1, reducing 2 is 8mm-30mm, be located at a left and right side at body two ends respectively, the axial line that promptly is located at reducing 1, reducing 2 departs from the (place of staggering the 4mm-15mm about the body axial line, and keep each position wall thickness of reducing evenly firm, reducing is connected with pipeline and one of body plays the vibration-absorbing and silencing effect.
Claims (3)
1, a kind of model muffler, it is characterized in that: it comprises body, the mouth of pipe at body two ends is made reducing, the axial line that the position of two ends reducing is located at this reducing departs from the body axial line, about each one, and keep each position wall thickness of reducing even.
2, model muffler according to claim 1 is characterized in that: described body is a copper tube.
