A structure of an exhaust regulating valve

Abstract

The invention provides an exhausting adjusting valve structure. The exhausting adjusting valve structure comprises a valve door, a valve body, a spring, a middle shaft and a blocking rod. Mounting plates are oppositely arranged on the two sides of the mounting end of the valve body, and two fixing plates corresponding to the two mounting plates are arranged on the two sides of the connecting end of the valve door; the middle shaft penetrates through via holes in the fixing plates and is connected with the mounting plates; the middle shat is rotatably matched with the via holes; the spiral section of the spring is arranged on the middle shaft in a sleeving mode, the first mounting end of the spring is clamped into a fixing opening of the valve door, and the second mounting end of the spring is clamped into a mounting opening of the valve body; the two ends of the blocking rod are connected with the sides, away from the valve door, of the two mounting plates correspondingly; a blocking block in blocking connection with the blocking rod is arranged at the connecting end of the valve door, and when the blocking block is in blocking connection with the blocking rod, the cooperating position of the valve door and valve body has a gap; and a blocking block movement opening corresponding to the blocking block is formed in the valve body. According to the exhausting adjusting valve structure, when the blocking block is in blocking connection with the blocking rod, the cooperating position of the valve door and valve body has the gap, so that knocking sounds are better prevented.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an exhaust regulating valve structure. Background technique [0002] With the continuous development of automobile products, users have higher and higher requirements for vehicle power and economy, and at the same time, they have increasingly stringent requirements for vehicle comfort. As a result, the upgrade and evolution of mufflers are becoming more and more extensive, and the application of dual-mode mufflers conforms to out. Exhaust regulating valves are widely used in dual-mode mufflers. The exhaust regulating valve is a valve that relies on the exhaust gas to push the valve, and relies on the opening of the valve to adjust the exhaust back pressure and improve the exhaust noise. structure. The exhaust regulating valve is used in the dual-mode muffler. When the engine is running at low speed, the valve opening is small or closed, so that the dual-mode muffler can obta...
