Problems solved by technology

Therefore, the use environment of the secondary air filter has changed. It is in a high temperature and high pressure environment. The traditional filter element pressing and sealing structure cannot meet the sealing requirements in this environment regardless of the material and structure. Therefore, how to It is a very urgent direction and goal for those skilled in the art to develop a filter element compression and sealing structure that can adapt to high temperature and high pressure environments

Embodiment Construction

[0017] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like figure 1 As shown, the present invention provides a compression sealing structure under high temperature and high pressure environment. The compression sealing structure is wedge-shaped, and a semicircular groove is provided on the top of the wedge-shaped compression sealing mechanism.

[0019] Wherein, the radius of the semicircular groove is 0.25 to 0.3 times the height of the wedge-shaped compression sealing structure, and the radii of the arcs on both sides of the semicircular groove are equal to the height of the wedge-shaped compression sealing structure 0.3-0.45 times of that, and the width of the bottom of the wedge-shaped compression sealing structure is 0.7-1 times of its height.

Abstract

The invention belongs to the technical field of vehicle filter cores, and particularly relates to a filter core pressing sealing structure in high-temperature and high-pressure environment. In order to realize the goal that a filter core pressing sealing mechanism can adapt to the high-temperature and high-pressure environment, the filter core pressing sealing structure in the high-temperature and high-pressure environment provided by the invention is characterized in that the appearance of the pressing sealing structure is in a wedge shape, the top of the wedge-shaped pressing sealing mechanism is provided with a semicircular groove, the deformation quantity of the wedge-shaped pressing sealing structure is 2 to 3mm, and the wedge-shaped pressing sealing structure is made of silicon gel materials with the highest resistance temperature being 200 DEG C. Therefore, the filter core pressing sealing structure has the advantages that the process is simple, the sealing is reliable, the cost is low, and the resistance on the high-temperature and high-pressure environment can be realized.

Description

technical field [0001] The invention belongs to the technical field of vehicle filter elements, and in particular relates to a compression and sealing structure of a filter element used in vehicles under high-temperature and high-pressure environments. Background technique [0002] The filter element is an important part of the air filter. Its function is to filter out the particulate matter in the intake air of the engine and prevent the particulate matter from entering the engine piston cylinder, causing the piston to rub against the cylinder block and damage the engine. At present, the air filter is located at the front end of the engine supercharger, and the operating environment is normal temperature and pressure. Compression seals are mostly used between the filter element and the air filter housing. like figure 2 As shown, the compression sealing structure is mostly made of foam rubber, and the shape is a simple wedge-shaped or square protrusion structure.
