How to deflate the automatic deflation valve
The automatic air release valve is an important component in heating systems, floor heating systems or plumbing equipment. It is used to remove air from the pipes and ensure the normal operation of the system. The following are detailed usage instructions and precautions for the automatic air release valve.
1. Working principle of automatic air release valve
The automatic air release valve senses the amount of air in the pipeline through a float or spring mechanism. When the air accumulates to a certain amount, the valve automatically opens to release the air to ensure smooth liquid circulation.
| Part name | Function |
|---|---|
| Float | Sensing air volume and triggering valve switch |
| valve | Control gas emissions |
| sealing ring | Prevent liquid leakage |
2. Deflation steps of automatic deflation valve
Here are the steps to manually operate the automatic bleed valve:
| steps | Operating Instructions |
|---|---|
| 1 | Turn off system power or water pump to ensure safety |
| 2 | Find the location of the automatic bleed valve (usually at the highest point of the pipe) |
| 3 | Use a screwdriver or special tool to gently loosen the screw on the top of the valve |
| 4 | Wait for the air to escape until there is water flowing out |
| 5 | Tighten the screws to restore system operation |
3. Common problems and solutions
The following are common faults and countermeasures of automatic air release valves:
| question | Reason | Solution |
|---|---|---|
| Valve leaking | The sealing ring is aged or damaged | Replace sealing ring or integral valve |
| Unable to deflate automatically | The float ball is stuck or blocked by impurities | Clean valve or replace float |
| Frequent deflation | Too much air intake into the system | Check pipe tightness |
4. Maintenance and maintenance suggestions
In order to ensure the long-term stable operation of the automatic air release valve, the following matters need to be paid attention to:
1.Regular inspection: Check whether the valve is working properly every quarter to avoid failure due to accumulation of impurities.
2.Cleaning and maintenance: Clean the inside of the valve at least once a year to prevent the float or spring mechanism from getting stuck.
3.Replacement cycle: It is recommended to replace the valve every 3-5 years, especially the sealing rings and other wearing parts.
5. Things to note when purchasing automatic air release valves
Please pay attention to the following parameters when purchasing:
| parameters | Description |
|---|---|
| Material | Brass or stainless steel is more durable |
| pressure level | Need to match system working pressure |
| Interface size | Same as pipe diameter |
Through the above content, users can fully understand the deflation method, troubleshooting and maintenance points of the automatic deflation valve. Correct use and maintenance of valves can effectively extend the life of equipment and improve system operating efficiency.
