The main reason for stainless steel quick coupling leakage
Anatomy of the quick coupling found. The main reason for air leakage of quick coupling: it is because of the deformation and damage of the sealing ring. The material of the sealing ring is ordinary rubber, shaped like a rectangular washer.
1, share a closed circle, no matter shut off or deflate. The two sides of the sealing ring are subject to pressure, the rubber ring deformation is serious, easy to damage; off gas, the spool trapezoidal surface in the spring force and high-pressure gas under the joint action of the rubber soft connector and the bowl-shaped sealing ring linear contact. Confinement pressure increases, not easy to leak, while the bowl-shaped confinement network backed by the seat of the positioning flange, not easy to shift, deformation is small. When venting, the male connector top open the spool. The role of the quick connector is both convenient and fast connection to the gas source, but also safe and reliable. In China, whether it is the automobile manufacturing industry, home appliance manufacturing enterprises, or maintenance of individual households, are a large number of compressed air as a power source, therefore, will be used to gas quick coupling. It can be said that as long as there is power will be used, and if the use of time is not long before the leakage, will waste energy consumption, increase production costs.
2, rubber flexible joint male end face and rubber ring end face contact, confinement pressure is relatively small, coupled with the end face is not flat, it is easy to leak.
The main reasons for the damage of quick coupling
1, the quick coupling shell is too thin, after a period of time, it will be damaged due to wear and corrosion.
2, quick coupling mother stomach and sub-body connection of the "O" ring for the anisotropic "O" ring, there is damage.
Stainless steel quick coupling precautions
1. Stainless steel quick coupling should not be used in the place where metal powder or sand dust is mixed in to prevent bad work or leakage.
2. Do not exceed the maximum tightening torque when installing the threaded type to prevent damage.
3. Do not use hoses with cracks to prevent leakage or disconnection.
4. If the hose is used in vibration or shock machines, the durability will be reduced.
5. The liquid used must be clean liquid filtered through the filter.
6. Do not disassemble the stainless steel quick coupling.
7. Do not use it for anything other than the liquid used.
9. Do not exceed the maximum pressure limit when using stainless steel quick coupling.
10. Do not use the stainless steel quick coupling outside the ambient temperature range to prevent wear and tear of the sealing material or leakage.
11. Don't make any artificial striking, bending, stretching to prevent breakage.
