How to read the switch of geothermal valve
The geothermal valve is an important part of the floor heating system. Knowing how to judge its on/off status is crucial for daily use and maintenance. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce you in detail to the switching judgment method of geothermal valves and provide structured data for reference.
1. Basic structure of geothermal valve
Geothermal valves usually consist of a valve body, a valve core, a handle or a knob. Depending on the type, the valve looks and operates differently. The following are the types and characteristics of common geothermal valves:
| Valve type | Appearance features | Switch status judgment method |
|---|---|---|
| ball valve | Lever-shaped handle | The handle is open when it is parallel to the pipe, and closed when it is perpendicular to the pipe. |
| gate valve | Hand wheel or knob | Turn clockwise to turn it off, turn it counterclockwise to turn it on |
| thermostatic valve | Knob with scale | The larger the number, the greater the opening, and 0 means closed. |
2. How to judge the switching status of geothermal valve
1.Observe the direction of the handle: For ball valves, the handle direction is the most intuitive basis for judgment. When the handle is in the same direction as the pipe, the valve is open; when the handle is perpendicular to the pipe, the valve is closed.
2.Check handwheel rotation: For gate valves, it is usually necessary to rotate the handwheel to open and close the valve. Turn the handwheel clockwise to turn it off, and turn it counterclockwise to turn it on. Some valves will have "open" and "closed" indicator arrows marked on the valve body.
3.View scale indication: Temperature control valves generally have a digital scale, usually 0 means closed, and the larger the number, the larger the opening. Some advanced temperature control valves also have LCD displays that can directly display the switch status.
4.listen to the sound of water flow: When you are unsure about the status of the valve, you can gently tap the pipe and listen to the sound of water flow. When it is on, you can usually hear the sound of water flowing, but when it is off, there is little or no sound.
3. Precautions when operating geothermal valves
| Things to note | Description |
|---|---|
| Operation strength | The valve should rotate easily. If resistance is encountered, do not operate it forcefully. |
| Regular inspection | It is recommended to check the valve status every quarter |
| winter protection | In cold areas, attention should be paid to antifreeze valves |
| Professional maintenance | Complex issues should be handled by professionals |
4. Frequently Asked Questions
1.What should I do if the valve cannot be fully closed?
It may be that the valve core is damaged or the sealing ring is aging. It is recommended to contact a professional to repair or replace the valve.
2.How to deal with a loose valve handle?
Check whether the fixing screw is loose. If it cannot be tightened, the handle or the entire valve needs to be replaced.
3.Is the lack of floor heating related to the valve?
It may be that the valve is not fully opened or blocked. Check the status of the valve and try to fully open it. If it fails, other reasons need to be investigated.

6. Summary
Correct judgment and operation of geothermal valves are the basis for ensuring the normal operation of the floor heating system. By observing the handle direction, rotation status and scale indication, the valve's switching status can be easily judged. In daily use, you should pay attention to operating specifications, perform regular inspections and maintenance, and contact professionals to handle complex problems in a timely manner. Hopefully this article will help you better understand and operate geothermal valves.
