[0002] The cylinder head is an important component of a compressor. It can seal the cylinder of the compressor and form a closed space together with the cylinder as the working chamber of the compressor. When the compressor is working, noise will be generated during the process of compressing low-pressure gas into high-temperature and high-pressure gas in the compressor cylinder. These noises are transmitted to the external environment through the cylinder head, which will cause noise interference to the surrounding staff. Therefore, it is of great practical significance to develop a new type of cylinder head with low noise during operation. Content of the Utility Model

Detailed Embodiments

[0017] Refer to Figures 1 to 4 A novel cylinder head shown in the figure, which includes a cover box 11. A cover plate frame 12 is provided on the cover box 11. The cover box 11 and the cover plate frame 12 are an integral structure. A partition plate 15 is provided inside the cover plate frame 12. First sound insulation boards 16 and second sound insulation boards 17 are provided on both sides of the partition plate 15. A sound insulation filler 18 and support columns 20 are provided between the first sound insulation board 16 and the second sound insulation board 17. First jacks 21 and second jacks 22 are respectively provided on the first sound insulation board 16 and the second sound insulation board 17. The two ends of the support column 20 are respectively inserted into the first jack 21 and the second jack 22. A fixing frame 19 is provided on the lower side of the second sound insulation board 17. A locking bolt 25 is provided between one side of the fixing frame 19 and the partition plate 15, and a locking bolt 25 is also provided between the other side of the fixing frame 19 and the inner wall of the cover box 11; the support columns 20 form a support between the first sound insulation board 16 and the second sound insulation board 17, avoiding the sound insulation filler 18 filled between the first sound insulation board 16 and the second sound insulation board 17 from being damaged by extrusion.

[0018] Further, both the first sound insulation board 16 and the second sound insulation board 17 are made of glass wool, and the sound insulation filler 18 is polyimide foam; the first sound insulation board 16 and the second sound insulation board 17 are boards made of glass wool, which can withstand the temperature and pressure inside the compressor and also have a certain sound insulation effect; the sound insulation filler 18 of polyimide foam is filled between the first sound insulation board 16 and the second sound insulation board 17, and has good noise absorption performance and high temperature resistance.

[0019] Further, a first magnet sheet 23 is arranged inside the first jack 21, and the first magnet sheet 23 is attached to one end of the support column 20; a second magnet sheet 24 is arranged inside the second jack 22, and the second magnet sheet 24 is attached to the other end of the support column 20; when both ends of the support column 20 are inserted into the first jack 21 and the second jack 22 respectively, the first magnet sheet 23 and the second magnet sheet 24 respectively adsorb the stainless steel support column 20 by magnetic force, so that the support column 20 can be stably supported between the first sound insulation board 16 and the second sound insulation board 17.

[0020] Further, a plurality of heat dissipation fins 14 are arranged at equal intervals between the side surface of the cover box 11 and the cover plate frame 12; the heat dissipation fins 14 increase the heat dissipation area of the cover box 11, which is beneficial to the efficient heat dissipation of the cylinder head.

[0021] Further, mounting holes 13 are arranged at the four corners of the cover plate frame 12; align the mounting holes 13 with the corresponding threaded holes on the compressor cylinder, and then screw on the bolts to install the cylinder head on the cylinder.

[0022] The working principle of the present utility model is that during the operation of the compressor, when the noise generated inside the cylinder is transmitted to the cylinder head, the noise first passes through the second sound insulation board 17 and is appropriately weakened by the second sound insulation board 17 made of glass wool, and then the noise passes through the sound insulation filler 18 made of polyimide foam. A large number of three-dimensional pore structures in the sound insulation filler 18 can effectively absorb the noise. The noise weakened by the sound insulation filler 18 is weakened again when passing through the first sound insulation board 16 made of glass wool, so that the noise transmitted outside the cylinder head is fully weakened, thereby preventing the surrounding staff from being disturbed by the noise.

[0023] The above is only the specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
