Abstract

A rotary multi-pipeline connecting system belongs to the technical field of machinery design and comprises a compressor, an engine, a turbine, connecting pipes, a valve seat, a valve body, a rotating shaft, an accommodating cavity, a fixing body, through pipes, a separation plate, a rotation body and a connection plate. One end of the rotation body extends into a first through pipe and has a sealed contact with the wall surface of the first through pipe; the other end of the rotation body is fixedly connected with the separation plate; one end of a second connecting pipe is communicated with an air exhaust pipe of the engine; and the other end of the second connecting pipe passes through the fixing body to be communicated with the first through pipe. When large differential pressure between the back and front parts of the turbine exists, the rotating body drives a butterfly valve to clockwise rotate; large high pressure exhausting and recirculation efficiency of the engine is achieved. The rotary multi-pipeline connecting system is rationally designed, simply structured and suitable for exhaust recirculation system of the engine.

Description

technical field [0001] The invention relates to an exhaust gas recirculation system in the technical field of mechanical design, in particular to a rotary multi-pipe connection system. Background technique [0002] Harmful emissions from engines are a major source of air pollution. With the increasing importance of environmental protection, the goal of reducing harmful emissions from engines has become an important direction for engine development in the world today. With the world's consumption of petroleum products increasing year by year, international oil prices remain high, and the economy of diesel vehicles is becoming more and more prominent, which makes diesel engines occupy an increasingly important position in vehicle power. Therefore, it is the primary task of diesel engine designers to carry out research on the control methods of harmful emissions from diesel engines. Exhaust gas recirculation system is to send a small part of the exhaust gas produced by the die...
