Problems solved by technology

[0003] Current technical disadvantages: With the upgrading of national emission standards, the temperature of exhaust gas is getting higher and higher, and the sealing ring and sealing rope of the segmented exhaust pipe are plastically deformed due to high temperature, thus losing elasticity, failure failure, and air leakage of the exhaust pipe In order to prevent the failure of seals, the current strategy is to increase the cost and improve the heat resistance level of materials. However, due to the immaturity and limitation of heat-resistant material technology, there are seal failures. Fault

Abstract

The invention discloses a segmental exhaust pipe with cooling blades. The segmental exhaust pipe comprises a first exhaust pipe body, a second exhaust pipe body, a plurality of sealing parts and the cooling blades. The first exhaust pipe body sleeves the second exhaust pipe body. The plurality of sealing parts are arranged at the joint of the first exhaust pipe body and the second exhaust pipe body. The cooling blades are fixed to the joint of the first exhaust pipebody and the second exhaust pipe body and are used for cooling the joint of the first exhaust pipe body and the second exhaust pipe body. Therefore, the segmental exhaust pipe with the cooling blades disclosed by the invention is simple and reasonable in structure and low in cost, increases the heat dissipation area and also reduces the temperature at the segmented positions of the exhaust pipe and the working temperature of the sealing parts.

Description

Technical field[0001]The invention relates to the technical field of internal combustion engines, in particular to a segmented exhaust pipe with cooling blades.Background technique[0002]At present, in order to prevent excessive axial expansion of the exhaust pipe of a six-cylinder diesel engine, the whole is usually divided into two or three sections in one section. The sections are sleeved together, and a sealing rope or a sealing ring is installed at the position of the sleeve. To reduce air leakage.[0003]Current technical shortcomings: With the upgrade of the national emission standard, the exhaust gas temperature is getting higher and higher. The sealing ring and the sealing rope of the segmented exhaust pipe are plastically deformed due to the influence of high temperature, thereby losing elasticity, failure and failure, and exhaust pipe leakage In order to prevent the failure of the seal, the current strategy is to increase the cost to improve the heat resistance level of the ...
