Embodiment Construction

[0030] Please refer to Figure 1 to Figure 8 As shown, the present invention discloses a valve 100 used in an automobile exhaust system. The valve 100 includes a valve seat 1 and a valve cover assembly matched with the valve seat 1 . In the illustrated embodiment of the present invention, the bonnet assembly includes a bonnet 2 matched with the valve seat 1 and a baffle 3 with at least one end fixed on the valve seat 1 . The valve seat 1 is provided with an exhaust opening 11 (such as Figure 5 shown). The valve cover assembly realizes the rotation by clamping. Depending on the exhaust pressure, the valve cover assembly, specifically the valve cover 2 in the illustrated embodiment of the present invention, can be in a covering position relative to the exhaust opening 11 (eg figure 1 ) with the open position (e.g. Figure 5 ) to rotate between.

Abstract

A valve for an automobile exhaust system comprises a valve seat and a valve deck assembly matched with the valve seat. The valve seat is provided with an exhaust opening. The valve deck assembly can rotate relative to the exhaust opening between the covering position and the opening position. The valve deck assembly achieves rotation in a clamping holding manner. In this way, the valve for the automobile exhaust system is simple in structure and easy to assemble.

Description

technical field [0001] The invention relates to a valve used in an automobile exhaust system, belonging to the technical field of tail gas post-treatment. Background technique [0002] US 5,971,098 discloses a valve used in an automobile exhaust system, wherein the valve includes a base, a valve cover and a torsion spring pressed against the base and the valve cover. However, due to the complex thermal environment and vibration environment in the automobile exhaust system, this design has relatively high requirements for the torsion spring. In addition, the structure of this valve is relatively complicated, which is not conducive to improving assembly efficiency. [0003] Therefore, it is necessary to design a novel valve to solve the above technical problems. Contents of the invention [0004] The object of the present invention is to provide a simple and easy-to-assemble valve for use in an automobile exhaust system. [0005] In order to achieve the above object, the ...
