There is a very important component part in the connector body, that is, the quick connector seal. Don't underestimate this accessory. It is an important part to prevent fluid leakage.
Quick connector O-ring is a kind of sealing material with circular section, which is widely used in many mechanical equipment. It can withstand certain temperature, pressure, different liquid or gas and other fluid media, playing a sealing role. Its existence solves the problem of hydraulic system leakage.
What are the advantages of quick connector O-ring compared with other seals?
1. The inner seal part of the connector body is simple in structure, compact in installation and light in weight.
2. The O-ring has the function of self sealing. It only needs one sealing element and can complete the sealing. For example, inserting a self sealing quick connector takes advantage of it.
3. Quick connector O-ring has excellent sealing performance. When the seal ring is fixed, there is almost no leakage. If it is used as a moving seal, leakage may occur only when the speed is fast.
4. The O-ring of quick connector has very small resistance when moving friction. It can also adapt to the use scenarios where the pressure changes.
5. The O-ring of quick connector is also a standard part. Its size groove has been standardized, and the production cost is low.
Compared with other sealing rings, quick connector O-ring also has the following three problems.
1. At the beginning of use, the resistance is relatively large, mainly the friction resistance.
2. If the pneumatic device is used for sealing, we must add lubricating oil to prevent wear.
3. Quick connector O-ring, as a spare part, is used together with the connector body. We have strict requirements on the size and progress of moving surface, groove clearance, etc.
