Abstract
The utility model discloses an air inlet transmission pipe of an exhaust silencer, which is characterized in that the air inlet transmission pipe forms a horn shape and the inner diameter of the air inlet end is smaller than that of the air outlet end. The air inlet transmission pipe has the advantages that the appearance is beautiful, the frequency conversion of air in the pipe can be realized, the utility model is favorable for the silencing of the air, the structure is simple and the use effect is good.
Description
Technical field
The utility model relates to a kind of pipe fitting, is a kind of air inlet transport tube of exhaust silencer specifically.
Background technique
Fig. 1 is exhaust silencer a kind of air inlet transport tube 1 commonly used, the pipe that this air inlet transport tube 1 equates for internal diameter, and inlet end 11 is identical with the area of outlet side 12.Because this air inlet transport tube 1 bore is identical everywhere, gas is constant at intraductal pressure, so the air inlet transport tube of this structure can only be finished the function that transport gas enters chamber, and can't realize the gas that enters is carried out frequency conversion, and then helps the function of noise reduction.
Summary of the invention
Main purpose of the present utility model provide a kind of handsome in appearance, can realize the frequency conversion of gas in the pipe and help the air inlet transport tube of the exhaust silencer of gas noise reduction.
This purpose of the present utility model adopts following technological scheme to realize: a kind of air inlet transport tube of exhaust silencer, and described air inlet transport tube is horn-like, and the internal diameter of described air inlet transport tube inlet end is less than the internal diameter of outlet side.
The utility model compared with prior art creatively uses the air inlet transport tube of horn shape shape, makes that gas pressure intensity reduced when waste gas entered the air inlet transport tube by the noise reduction suction tude, has realized the single-conversion function, thereby has helped noise reduction.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of exhaust silencer air inlet transport tube in the prior art;
Fig. 2 is the structural representation of the utility model exhaust silencer air inlet transport tube.
Embodiment
As shown in Figure 2, a kind of air inlet transport tube 2 of exhaust silencer, this air inlet transport tube 2 is horn-like, and the internal diameter of its inlet end 21 is less than the internal diameter of outlet side 22.
Claims (1)
1, a kind of air inlet transport tube of exhaust silencer is characterized in that: described air inlet transport tube (2) is horn-like, and the internal diameter of described air inlet transport tube (2) inlet end (21) is less than the internal diameter of outlet side (22).
