Description

Exhaust brake butterfly valve with novel support structure

Technical Field

The utility model relates to the technical field of exhaust brake butterfly valves, in particular to an exhaust brake butterfly valve with a novel bracket structure.

Background

In recent years, the development of the heavy trucks in China is rapid, the product varieties are increasingly abundant, the product quality and the technical level are continuously improved, the heavy trucks are composed of various parts, and the use environments and the bearing conditions of different parts are different, so that the automobile parts are inevitably invalid in the use process, and the service life requirements on the exhaust brake butterfly valve are increasingly high. The butterfly valve bracket assembly is arranged between the supercharger and the exhaust pipeline, is easy to vibrate due to the influence of vibration of an automobile engine and an exhaust pipeline, and the service life of the butterfly valve bracket assembly is also improved. When the vibration of the automobile engine is too large or the auxiliary support is not effective, the support plate is inevitably broken and the like, so that the exhaust brake butterfly valve assembly is invalid.

The exhaust brake valve assembly bracket and the limiting part at the present stage mostly adopt three parts of a bracket component, a limiting plate and a limiting screw, the installation procedure is complex, the limiting plate and the bracket plate are fastened by bolts and nuts, the processing and installation costs of the limiting plate are high, and the exhaust brake valve assembly bracket is used in a high-frequency vibration environment, and failure modes such as loosening of the limiting plate are easy to occur.

Disclosure of Invention

Aiming at the situation, in order to make up the existing defects, the utility model provides a novel support structure exhaust brake butterfly valve with greatly improved stability and service life compared with the traditional support structure.

The utility model provides the following technical scheme: the utility model provides an exhaust brake butterfly valve with a novel bracket structure, which comprises a bracket plate, a screw, a valve body, a limit screw and a nut, wherein the bracket plate is fastened on the valve body through the screw, the limit screw is directly fastened on the bracket plate through the nut, and the bracket plate is of a bending-free integrated structure.

The beneficial effects obtained by the utility model by adopting the structure are as follows: the utility model provides a novel support structure exhaust brake butterfly valve, which has the following advantages:

(1) The newly designed support plate reduces the material weak area caused by bending deformation, reduces stress, and greatly prolongs the service life compared with the original support plate through finite element analysis;

(2) The newly designed support plate is of an integrated structure, and the limit screw is directly installed, so that the procedures of processing and installing the limit plate are omitted, the processing cost and the installation cost are saved, and the working efficiency is improved.
