The utility model relates to a rationally, rational in infrastructure, easy operation can the noise reduction cooling.
Description
Technical field
This utility model relates to a kind of gasoline engine noise suppressor, belongs to mechanical manufacturing field.
Background technology
Along with society's concern to noise, and the continuous propelling that country is to noise level limit, the work of gasoline engine noise reduction is further affected by manufacturing attention. In prior art, gasoline engine aerofluxus generally use punch forming and weld strengthening heat-resisting steel sheet and plate be used as heat shield, this heat shield can not degrading radiation noise, can not reduce again self vibration, therefore shielding noise effects poor.
Summary of the invention
For solving the problems referred to above, the utility model proposes novel gasoline engine noise suppressor.
The utility model discloses a kind of gasoline engine noise suppressor, including muffler assembly, spark arrester, screw, nut, acoustic filter pad, high-temperature steel inner cord, high temperature resistant steel plate outer layer, high-temperature resistant sound absorption fibrous layer. Described high-temperature steel inner cord welds with high temperature resistant steel plate outer layer, described high-temperature resistant sound absorption fibrous layer is laid between high-temperature steel inner cord and outer layer, described spark arrester and muffler assembly are connected by screw, and described acoustic filter pad is connected by nut with muffler assembly.
Described muffler assembly has high-temperature steel inner cord, high temperature resistant steel plate outer layer and high-temperature resistant sound absorption fibrous layer.
Compared with prior art, it has the advantages that this utility model adds the design of intelligence on traditional gasoline acoustic filter basis to this utility model so that it is bring more noise reduction and arc control function. This utility model adds spark arrester on traditional gasoline acoustic filter basis, it is therefore prevented that dangerous generation, adds safety coefficient. This utility model adds high temperature resistant and sound absorption fibrous interlayer, effective absorption of noise and pipe surface radiation noise on traditional gasoline engine noise suppressor, thus playing good noise reduction, improves the reliability and security of whole device.

Detailed description of the invention
Consult the gasoline engine noise suppressor shown in Fig. 1 and Fig. 2, including muffler assembly 1, spark arrester 3, screw 5, nut 6, acoustic filter pad 7, high-temperature steel inner cord 8, high temperature resistant steel plate outer layer 2, high-temperature resistant sound absorption fibrous layer 4.Described high-temperature steel inner cord 8 welds with high temperature resistant steel plate outer layer 2, described high-temperature resistant sound absorption fibrous layer 4 is laid between high-temperature steel inner cord 8 and outer layer 2, described spark arrester 3 is connected by screw 5 with muffler assembly 1, and described acoustic filter pad 7 is connected by nut 6 with muffler assembly 1.
Described muffler assembly 1 has high-temperature steel inner cord 8, high temperature resistant steel plate outer layer 2 and high-temperature resistant sound absorption fibrous layer 4.
This utility model hydraulic stripper machine adds the design of intelligence on traditional gasoline acoustic filter basis so that it is bring more noise reduction and arc control function. This utility model hydraulic stripper machine adds spark arrester on traditional gasoline acoustic filter basis, it is therefore prevented that dangerous generation, adds safety coefficient. This utility model adds high temperature resistant and sound absorption fibrous interlayer, effective absorption of noise and pipe surface radiation noise on traditional gasoline engine noise suppressor, thus playing good noise reduction, improves the reliability and security of whole device.
Embodiment described above is only that preferred implementation of the present utility model is described, and not design of the present utility model and scope is defined. Under the premise without departing from this utility model design concept; various modification that the technical solution of the utility model is made by this area ordinary person and improvement; protection domain of the present utility model all should be dropped into; the technology contents that this utility model is claimed, all records in detail in the claims.
