Abstract

The invention discloses a throttle valve gasket comprising a gasket body. The gasket body is an enclosed ring, the enclosed ring is formed by connecting two ends of a great semicircle segment and an irregular arc segment through tangent straight flanges, a connecting boss is further arranged on the outer side of the great semicircle segment, multiple pairs of bosses are arranged on the inner and outer side walls of the gasket body, each boss is integrally semi-cylindrical, and two ends of each boss are in transition connection with the side walls of the gasket body through hemispheres. The throttle valve gasket fits with a throttle valve in shape and is good in assembly effect and small in clearance, so that sealing effect is improved.

Description

technical field [0001] The invention relates to gaskets used in auto parts, in particular to a throttle valve body gasket. Background technique [0002] In the process of modern industrial production becoming more and more developed, automobiles have become an indispensable means of transportation for people's lives, and their output is increasing day by day. With the emphasis on personal and traffic safety issues, people pay more and more attention to the quality of cars. The hydraulic control automatic transmission in the automobile structure uses the throttle valve to reflect the size of the throttle opening. The function of the throttle valve is to generate a control oil pressure proportional to the throttle opening, which is transmitted to the main pressure regulating valve and shift valve. , Control the main oil pressure and shift, generally divided into two types: mechanical throttle valve and vacuum throttle valve. The sealing requirements of the throttle val...
