Why do you need to equip the air compressor with a check valve: the core device to prevent reverse flow

The air compressor will produce high-pressure gas. If there is no effective control measures during shutdown, it may cause the internal medium to flow back, which may damage the equipment and even cause safety accidents. At this point will need to use the check valve to solve this problem.

It can automatically sense the direction of pressure change and close the channel in time to prevent reverse flow, thereby protecting the host from damage and maintaining the system balance.

Multi-size adaptation analysis: from 3/4 inch to more choices

there are many types of check valves on the market, among which the common ones are standard models with a diameter of 3/4 inches and other specifications and sizes for consumers to choose and adapt to different types of environmental requirements.

Specifically, small domestic air pressure pumps are usually sufficient for basic use with smaller caliber versions; for large industrial facilities, larger pipe connection ports are required to ensure sufficient flow supply capacity. Therefore, it is particularly important to make a clear decision after the actual situation.

Key Performance Indicators: How to Choose the Best Product

In addition to the appropriate size, several core parameters need to be paid attention to for comprehensive evaluation:

Sealing : Products made of high-quality materials with fine, smooth and flawless surface treatment have better long-term reliability and durability;

pressure range : the maximum allowable workload value given by different brands is quite different. please be sure to confirm whether the value meets the rated standard of your machine and leave a certain margin above it to avoid accidental overload and increase the risk of failure.

response speed : fast and accurate action switching is one of the prerequisites to ensure the continuous and smooth progress of the whole process, so problems such as slow response or Caton need to be avoided as much as possible.

Installation tips and precautions: Make sure to perfectly match your device

The correct installation method is also the key to the desired effect. First of all, you should carefully check whether there are burrs or other obstacles at the interface, which will affect the degree of close fit, and then start the operation steps as follows:

-insert the selected check valve into the specified position according to the direction indicated by the mark;

-Use a wrench to tighten the nut properly and fix both ends without loosening to complete the preliminary assembly process;

-Finally turn on the power and run for a period of time to observe whether there are signs of leakage. If everything is normal, it means that the installation is successful.

Maintenance advice: Tips for extending the life of check valves

In order to keep the check valve in good working condition, regular maintenance activities are essential. For example, clean up the accumulated dust particles to prevent unnecessary trouble caused by blocking the import and export parts. In addition, attention should be paid to lubricating some moving components to reduce friction loss and prolong life.

All in all, the rational use of the above knowledge can help everyone manage their own air compression equipment system more scientifically while enjoying a higher level of security service experience.
