Multi-pipe efficient easy-installing exhaust pipe structure

Abstract

The invention discloses a multi-pipe efficient easy-installing exhaust pipe structure comprising short barrel type exhaust pipes. A triangular flange is welded between the short barrel type exhaust pipes, reinforcing plates are welded to the two sides of the joint of the short barrel type exhaust pipes and the triangular flange, and the triangular flange is provided with an anti-off nut. When themulti-pipe efficient easy-installing exhaust pipe structure is used and an engine runs at a low speed, the temperature of tail gas is low, the size of a gasbag changes little, the gap between a firstseparation plate and a second separation plate is small, at the moment, return pressure in the pipes prevent waste gas from rushing out, mixed gas reaches complete combustion, fuel is saved, and the burden of a tail gas purification device is reduced. When the engine runs at a high speed, the temperature of tail gas is high, size change of the gasbag is large, the first separation plate and the second separation plate are separated, at the moment, waste gas can be discharged from the device, heat accumulation in the device is prevented, and service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of exhaust pipes, in particular to a multi-pipe exhaust pipe structure with high efficiency and easy installation. Background technique [0002] The exhaust pipe is installed between the engine exhaust manifold and the muffler, so that the entire exhaust system is flexibly connected, thereby reducing vibration and noise, facilitating installation and prolonging the life of the exhaust muffler system. The existing exhaust pipe is usually a pipe, because the diameter of the exhaust pipe cannot be enlarged at will. Therefore, for an engine with a large displacement, when the engine is running at a high speed, the gas discharge will not be timely. It is easy to cause heat accumulation in the exhaust pipe and affect the life of the exhaust pipe. When the engine is running at a low speed, the incompletely burned fuel is directly discharged, resulting in energy loss and easy to cause environmental pollution. Cont...

The existing exhaust pipe is usually a pipe, because the diameter of the exhaust pipe cannot be enlarged at will. Therefore, for an engine with a large displacement, when the engine is running at a high speed, the gas discharge will not be timely. It is easy to cause heat accumulation in the exhaust pipe, which affects the life of the exhaust pipe. When the engine is running at low speed, the incompletely burned fuel is directly discharged, resulting in energy loss and easy to cause environmental pollution.
