Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile protection valve shell, specifically to a kind of automobile protection valve aluminum die casting shell of convenient installation and disassembly. BACKGROUND

[0002] In the automobile industry, the protection valve is one of the key components to ensure the normal operation of each system of the automobile, and its stability and reliability are crucial. The traditional protection valve shell is mostly made of steel or other metal materials, which has certain strength and durability, but there are many inconveniences in the process of installation and disassembly, especially at the connection between the valve body and the sealing base, it is difficult to achieve quick and effective sealing.

[0003] In the prior art, there are various installation methods between the valve body and the sealing base of the automobile protection valve, but the common problem is poor sealing effect. This is mainly due to the difficulty in ensuring the fitting accuracy of the sealing surface during installation, or the improper selection and processing of the sealing material, resulting in unstable sealing performance and easy leakage. Once leakage occurs, it will not only affect the normal operation of the automobile, but also may pollute the surrounding environment, and even cause safety accidents.
