Analysis of the causes of damage to the valve body of this gas valve
Thread Content
Medium hydrogen； The pressure is 20 kilograms. What causes damage to the valve body?
There are many reasons; you will need to analyze them on your own. The following is for reference only: 1. The operating conditions do not fall within the range required by the material, especially extreme fluctuations in operation that can cause damage to the material. 2. Due to the material of the intake valve itself; if this type of problem occurs alone, it is necessary to analyze aspects such as the material and installation. 3. Whether the usage has exceeded the specified period. These are my personal opinions for reference only; please forgive any inaccuracies!
Material issues should be the main one (personal opinion)
1. Under physicochemical analysis, check the hardness. 2 is rare.
With solid reasons, I lean more towards a material issue
Received； You really get what you pay for in terms of equipment, haha
Check the material of the gas valve; if valves of the same grade are made of the same material and show no damage, examine the installation issues. If there is nothing wrong with the valve disc, then check whether the set screws holding the valve frame in place are loose, as well as whether the fluctuations in gas pressure during operation could cause the valve to strike the valve frame
When it was first installed, were there any unusual noises during operation? Are the valve stem seals and caps related to large valve clearance? Has the compression ratio exceeded the design value?
