Abstract

The invention discloses a lower stator of a guiding motion valve core of an automobile exhaust backflow controlling valve, comprising a housing, a gasket and a stator, wherein a step is arranged at the upper part of the stator; holes are arranged at the bottom surface of the housing and in the middle of the gasket; and the gasket and the housing are successively sleeved on the step and are fixed through being riveted on the top of the step. The lower stator provided by the invention has the advantages that: the lower stator of the guiding motion valve core of the automobile exhaust backflow controlling valve is disassembled to split type parts and then assembled to a whole; each part are independently processed; and therefore, the processing difficulty is reduced, the raw material loss is decreased, the batch fabrication can be formed and the production efficiency is increased.

Description

technical field [0001] The invention relates to a stator of a valve core, in particular to a lower stator of a guide motion valve core of an automobile tail gas backflow control valve. Background technique [0002] The lower stator of the directional movement valve core of the automobile exhaust backflow control valve is an integral structure made by cutting. Although its precision can meet the requirements, due to the irregular shape and structure of the lower stator, the integral directional movement valve of the automobile exhaust backflow control valve The stator under the core is difficult to process, consumes a lot of raw materials, and has low production efficiency. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of the present invention is to provide a lower stator of the directional movement valve core of the automobile exhaust return control valve that is easy to manufacture, which not only maintains the sha...
