Abstract
The utility model discloses a gasoline engine noise suppressor, comprising a housing body which is formed by an upper cover and a lower cover. The middle portion of the housing body is provided with an inner through pipe which is fixed by a flange disk, and the lower portion of the housing body is provided with an exhaust pipe. The inner side of the upper cover is provided with noise suppressing asbestos which is pressed tightly by a lining pressing plate, and a layer of temperature resistant sealing gum is coated at the combining position of the upper cover and the lower cover. The edges of the upper cover adopt fastening to cover the edge of the lower cover. The gasoline engine noise suppressor has simple production and low cost; after a layer of temperature resistant sealing gum is coated at the combining position of the upper cover and the lower cover, the edges of the upper cover and the lower cover are fastened and covered. Since the temperature resistant sealing gum is in a pasty cream body, pits and gaps are filled with the temperature resistant sealing gum fully after the housing body is pressed. After the gasoline engine noise suppressor is solidified, the upper cover and the lower cover of the gasoline engine noise suppressor form an integral body and are sealed tightly, and the air leakage is avoided.
Description
Technical field: the utility model belongs to the technology of gasoline engine field, relates to the following petrol engine silencing apparatus of a kind of 5KW.
Background technique: the petrol engine silencing apparatus requires the preparation process strictness, and the binding site between the upper and lower cover requires tight, air tight.For this reason, there is the junction between the silencing apparatus upper and lower cover to adopt welding technique such as roll welding, makes its sealing.But this technical costs height, efficient are low, as weld and irregularly have the solder joint gas leak phenomenon, and the silencing apparatus easy deformation.Also have between the silencing apparatus upper and lower cover and install sealing gasket additional, though this technology has reduced cost, because sealing gasket and silencing apparatus upper and lower cover area of contact are too small, in the fastening bound edge process sealing gasket dislocation can appear, cause the poorly sealed gas leakage of silencing apparatus, up-to-standard rate is less than 95%.
Summary of the invention: the purpose of this utility model provides good seal between a kind of upper and lower cover, gastight petrol engine silencing apparatus, to overcome the deficiencies in the prior art.
For achieving the above object, the utility model petrol engine silencing apparatus, it comprises the housing that upper and lower cover is formed, siphunculus is fixed by flange plate in establishing in the housing middle part, lower housing portion is provided with outlet pipe, the inboard of loam cake is provided with the noise reduction asbestos and is compressed by the lining pressing plate, and the binding site between the said upper and lower cover scribbles one deck heatproof sealer, and the edge of said loam cake adopts the fastening bound edge to be coated on the edge of said lower cover.
The utility model is made simply, cost is low, after the binding site between the silencing apparatus upper and lower cover scribbles one deck heatproof sealer, fastens bound edge again.Because the heatproof sealer is lotion in the pasty state, can make and behind pressurized, fully fill concave point, slit between the housing.After the curing, the silencing apparatus upper and lower covers forms one and makes it strict seal, has stopped gas leakage.The utility model silencing apparatus is high temperature resistant 550～700 ℃, up-to-standard rate reaches 100%.
Description of drawings: Fig. 1 the utility model structural representation;
The local structure for amplifying schematic representation in A place among Fig. 2 Fig. 1.
Among the figure 1, lower cover 2, loam cake 3, flange plate 4, interior siphunculus 5, lining pressing plate 6, noise reduction asbestos 7, outlet pipe 8, heatproof sealer
Embodiment: with reference to the accompanying drawings, the utility model petrol engine silencing apparatus, it comprises the housing that upper and lower cover 2,1 is formed, siphunculus 4 is fixing by flange plate 3 in establishing in the housing middle part, lower housing portion is provided with outlet pipe 7, the inboard of loam cake 2 is provided with noise reduction asbestos 6 and is compressed by lining pressing plate 5, and the binding site between the said upper and lower cover 2,1 scribbles one deck heatproof sealer 8, and the edge of said loam cake 2 adopts the fastening bound edge to be coated on the edge of said lower cover 1.
