There will be safety valve in electric heating furnace, how to avoid failure when using it? Let's give you a detailed introduction.
In the winter heating work, safety is a very important problem, so now the heating furnace in production will install a safety valve, but the safety valve will inevitably fail, let's see the cause of the failure of the safety valve of the heating furnace.
1. The installation and maintenance process is poor and the calibration is not accurate.
2. During the operation, the safety door parts are deformed and jammed, and the spring fails, which makes the opening and closing blocked and the action is inflexible.
3. Long term closure, valve core and valve seat adhere to each other or other parts rust.
4. Frequent opening and closing causes the sealing surface to be scoured and damaged.
5. There are impurities between valve core and valve seat, and the connection is not tight.
The above is the reason for the failure of the safety valve of the heating furnace, hoping to help everyone.
