The main cause of air leakage in quick connectors

Anatomical findings on quick connectors. The main cause of air leakage in quick connectors is deformation and damage of the sealing ring.
The sealing ring is made of ordinary rubber and is shaped like a rectangular gasket.
1. Sharing a sealing ring, regardless of whether the air is closed or deflated. Both sides of the sealing ring are under pressure respectively, and the rubber ring is severely deformed and easily damaged;
When the gas is closed, the arc surface of the valve core is in linear contact with the bowl-shaped sealing ring under the combined action of spring force and high-pressure gas. The sealing pressure is increased, making it less likely to leak. At the same time, the bowl-shaped sealing net is backed by a seat with a positioning flange, making it difficult to shift and have small deformation.
When venting, the male connector opens the valve core. The function of the quick connector is to not only facilitate and quickly connect the air source, but also be safe and reliable.
In our country, whether it is the automobile manufacturing industry, home appliance manufacturing companies, or self-employed maintenance workers, they all use compressed air as a power source. Therefore, air quick connectors are used. It can be said that as long as there is power, it will be used. If it leaks after a short period of use, it will waste energy and increase production costs.
2. The male end face of the rubber soft joint is in contact with the end face of the rubber ring, so the sealing pressure is relatively small. In addition, if the end face is uneven, it is easy to leak.
