Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0022] see Figure 1 to Figure 3 , the exhaust muffler structure of the automobile pressure relief valve shown includes pressure relief valve exhaust pipe 3 and air filter outlet pipe 1. The interface 11, the other end of the exhaust pipe 3 of the pressure relief valve is used for fixed connection with the pressure relief valve, which is not shown in the figure. It also includes a muffler pipe 2 arranged in the exhaust pipe 3 of the pressure relief valve. The material of the muffler pipe 2 is die steel, which is low in cost and has a certain rigidity, which satisfies the operating conditions of the vehicle. The outer diameter of the muffler pipe 2 matches the inner diameter of the exhaust pipe 3 of the pressure relief valve. One end of the muffler pipe 2 facing the interface 11 is inserted into the interface 11, and the inner hole at the other end is a tapered hole ...
