Description
Technical field
The utility model relates to a kind of small diesel engine venting gas appliance horizontal double-cavity silencer used.
Background technique
Silencing apparatus used in venting gas appliance on existing small diesel engine, generally sound absorbing material is set in cavity to realize sound-absorbing damping, structure is comparatively complicated, by diesel engine work vibration influence in using process, sound absorbing material easily comes off and causes noise reduction to reduce, have impact on the exhaust effect of diesel engine, the self structure of silencing apparatus is unfavorable for installing firmly simultaneously, and manufacture cost is also higher.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides the small diesel engine horizontal double-cavity silencer that a kind of structure is simple, easy to make, erasure effect is desirable.
The utility model solves the technological scheme that its technical problem adopts: a kind of small diesel engine horizontal double-cavity silencer, there is upper shell, lower shell body, suction tude and steam outlet pipe, upper shell fastens with lower shell body and welds, described upper shell and the junction of lower shell body are provided with silencing board, upper cavity is formed between silencing board and upper shell, lower chamber is formed between silencing board and lower shell body, suction tude is fixed on upper shell to stretch in upper cavity and fixes with silencing board, steam outlet pipe is fixed on lower shell body to stretch in lower chamber and fixes with silencing board, suction tude exposed junction is connected with cylinder relief opening, the exposed junction of steam outlet pipe is communicated with air, suction tude perisporium is evenly equipped with the noise reduction hole communicated with upper cavity, steam outlet pipe perisporium is evenly equipped with the noise reduction hole communicated with lower chamber, silencing board is evenly equipped with the bloop of matrix arrangement.
Further, for improving silencing apparatus installation strength, described suction tude is fixed through silencing board and lower chamber inwall.
Described upper shell and lower shell body in conjunction with periphery, there is adpting flange.
The beneficial effects of the utility model are: in the utility model, gas, by twice expansion of upper and lower cavity, significantly reduces exhaust sound, and the noise reduction hole of reasonable Arrangement and bloop, further improve the tonequality of noise, make the irritated sound originally affecting people's sense of hearing become soft.

Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of small diesel engine horizontal double-cavity silencer as shown in Figure 1, there is upper shell 1, lower shell body 2, suction tude 3 and steam outlet pipe 4, the adpting flange 10 that upper shell 1 and lower shell body 2 are had in conjunction with periphery by it fastens integrally welded, junction along upper shell 1 and lower shell body 2 is provided with silencing board 5, upper cavity 6 is formed between silencing board 5 and upper shell 1, lower chamber 7 is formed between silencing board 5 and lower shell body 2, suction tude 3 exposed junction is connected with cylinder relief opening, and the exposed junction of steam outlet pipe 4 is communicated with air.
Suction tude 3 be fixed on upper shell 1 stretches into fixing with silencing board 5 in upper cavity 6 after fix through silencing board 5 and lower chamber 7 inwall again, the installation strength of silencing apparatus can be improved so after mounting, steam outlet pipe 4 is fixed on lower shell body 1 to stretch in lower chamber 4 and fixes with silencing board 5, the noise reduction hole 8 communicated with upper cavity 6 is evenly equipped with at the perisporium of suction tude 3, the noise reduction hole 8 communicated with lower chamber 7 is evenly equipped with at steam outlet pipe 4 perisporium, silencing board 5 is evenly equipped with between suction tude 3 and steam outlet pipe 4 bloop 9 that matrix arranges in scope
In the utility model, gas is by twice expansion of upper and lower cavity 6,7, significantly reduce exhaust sound, the noise reduction hole 8 of uniform arrangement and bloop 9, be conducive to the tonequality improving noise further, make the irritated sound originally affecting people's sense of hearing become soft, more meet the tonequality frequency requirement of people's normal hearing, achieve the object of abundant noise reduction.
Above-mentioned mode of execution is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
