In above-mentioned a kind of composite engine silencing apparatus, the baffle plate boss shape ringwise of described assembly pipe one end, and there is outside thread, the baffle plate concave table ringwise of the assembly pipe the other end, and have internal thread, and adjacent two assembly pipes connect respectively by the baffle plate matching thread of correspondence.
In above-mentioned a kind of composite engine silencing apparatus, two adjacent assembly pipes connect rear welding respectively by the baffle plate matching thread of correspondence.
Be threaded connection very convenient, and more stable by being welded and fixed after connecting.
In above-mentioned a kind of composite engine silencing apparatus, the baffle plate of described assembly pipe one end welds with cylindrical shell and core body pipe, and the baffle plate of the other end and cylindrical shell and core body pipe removably connect.
Therefore silencing cotton can be adjusted.
In above-mentioned a kind of composite engine silencing apparatus, be positioned on the cylindrical shell on the assembly pipe at baffler two ends and have conically shaped, and the large end of conically shaped is connected with cylindrical shell, small end is connected with core body pipe one end.
Compared with prior art, the utility model tool has the following advantages:
Closing due to silencing cotton is located in space that cylindrical shell, core body pipe and baffle plate surround, cylindrical shell, core body pipe, baffle plate and silencing cotton are combined to form assembly pipe, and some assembly pipes are connected to form baffler respectively by baffle plate head and the tail, therefore assembly pipe can length do short, avoid that cylindrical shape is elongated to be caused silencing cotton to be filled unevenly making noise elimination poor stability, and different assembly pipe quantity can be selected as required to install, therefore more flexible.
