Special Purpose Safety Valve

Special purpose safety valves refer to safety valves used on various special equipment, as well as specialized safety valve products used on various professional mechanical equipment and pipelines. The main function of the air compressor safety valve is to protect the safety valve of the air compressor equipment. When the pressure in the compressed air system exceeds the rated pressure of the safety valve, the safety valve will open and discharge excess gas, thereby preventing the system pressure from being too high and ensuring the safety of the air compressor equipment. For example, the working principle of the vacuum negative pressure safety valve is based on pressure difference control. When the internal pressure of the system is lower than the set value, the valve will automatically open, allowing air to enter the system to balance the pressure difference between the inside and outside of the pipeline equipment and prevent damage caused by negative pressure in the system. Its core components include a spring and a valve disc. When the vacuum level in the system drops to a specified value (usually below one atmosphere), the valve automatically opens and releases the air in the pipeline into the atmosphere; When the pressure returns to the normal range, the valve automatically closes and locks at the set opening.
