The invention discloses a connecting pipe applied to automotive exhaust purification equipment. The connecting pipe applied to the automotive exhaust purification equipment comprises a first connecting pipe, a first outer pipe, a first inner pipe, a first boss, a first sealing ring, a first fastening bolt, a first stop block, a second connecting pipe, a second outer pipe, a second inner pipe, a second boss, a second sealing ring, a second fastening bolt, a second stop block, a hoop, an adjusting nut, an adjusting bolt and the like. The connecting pipe is connected with a corrugated pipe through the first outer pipe arranged in the first connecting pipe, and connected with an exhaust pipe through the second outer pipe in the second connecting pipe, then the first inner pipe and the second inner pipe are matched and fixed through the hoop, the first outer pipe and the first inner pipe are fixed through the first fastening bolt, the second outer pipe and the second inner pipe are fixed through the second fastening bolt, installation and connection between the corrugated pipe and the exhaust pipe are realized, installation is convenient and fast, and the connecting strength is high. Asthe first sealing ring, the second sealing ring and a third sealing ring are arranged, the sealing performance of the connecting pipe is guaranteed.
Description
Technical field: [0001] The invention belongs to the technical field of purification equipment, and in particular relates to a connecting pipe used on automobile exhaust purification equipment. Background technique: [0002] Automobile exhaust purification equipment is the purification and emission equipment that must be installed on all automobiles and vehicles. It can effectively control the exhaust pollution of automobiles and reduce the emission of carbon monoxide, black smoke and other toxic gases. [0003] The automobile exhaust purification equipment realizes the connection with the exhaust pipe through the connecting pipe, and the existing connecting pipe is usually a corrugated pipe or a hose. The flange is connected to the exhaust pipe or the purification processor through the flange, but because of the position of the installation hole, it is inconvenient to install, and some need to twist the bellows or hose, which is easy to cause damage to the bellows or hose ...
