Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: muffler body 1, exhaust return bend 2, first flange 3, second flange 4, rain-proof lid 5, connecting pin 6, connecting rope 7, gas vent 8, rain-proof ring 9, spout 10, connecting rod 11.
The embodiment is basically as shown in the attached figure 1: a silencer comprises a silencer body 1 and an exhaust elbow 2, wherein the silencer body 1 is connected with the exhaust elbow 2. One side of the silencer body 1 is provided with two connectors for connecting with an exhaust pipe.
The surface of the silencer body 1 is sprayed with silver powder high-temperature resistant paint (such as acrylic polyurethane silver paint). The silencer in the embodiment further comprises a first connecting flange 3, a second connecting flange 4 and two corrugated pipes; the muffler body 1 and the exhaust elbow 2 are connected by a first connecting flange 3. Connect muffler body 1 and exhaust return bend 2 through first flange 3, not only can guarantee the joint strength of muffler body 1 and exhaust return bend 2, still convenient operation when connecting. One end of each of the two corrugated pipes is communicated with the connecting port through a second connecting flange 4, and the other end of each of the two corrugated pipes is connected with the exhaust pipe. The corrugated pipe is favorable for exhaust emission, the environmental pollution caused by engine exhaust is minimized, and the vibration of an exhaust system can be absorbed to prevent excessive thermal deformation. The silencer body 1 and the corrugated pipe are connected through the second connecting flange 4, so that the connection strength of the silencer body 1 and the corrugated pipe can be guaranteed, and the silencer is convenient to operate when being connected.
The muffler body 1 is externally provided with a heat shield. The arrangement of the heat insulation cover can enable the silencer body 1 to have a good snow-proof, fireproof and heat-insulation function, and the requirement for normal use under severe environment can be met.
