Safety valves provide safety protection in the system. When the system pressure exceeds the specified value, the safety valve is opened, and a part of the gas/fluid in the system is discharged into the atmosphere/pipe, so that the system pressure does not exceed the allowable value, thereby ensuring that the system does not cause an accident due to excessive pressure.
Resin sand casting plays a barrier and isolation role between castings and moulds to achieve the purpose of anti-sticking sand. It can also effectively prevent the oxidation of high-temperature liquid metals, so that no chemical reaction occurs during the contact process between the moulds and high-temperature liquid metals, and can absorb and digest gases containing nitrogen, sulphur and carbon.
The installation notes
1. All safety valves should be installed vertically.
2. There should be no resistance at the exit of the safety valve to avoid pressure.
3. The safety valve should be specially tested before installation and checked for tightness.
4. Regular inspection of the safety valve in use.
