How to ensure the reliable operation and maintenance of Pressure Relief Valve in chemical production?

Pressure Relief Valve maintains dynamic balance with the internal pressure of the system through a force balancing mechanism such as a built-in spring or a heavy hammer. When the system pressure reaches or exceeds the set value, the valve will automatically open, allowing the medium to flow out through the discharge port, thereby reducing the internal pressure of the system. When the pressure drops below the set value, the valve will automatically close and restore the sealing state. This automatic pressure control mechanism ensures the pressure stability and safety in the chemical production process.
In chemical production, it is very important to choose a suitable Pressure Relief Valve. First, the rated pressure and material of the valve need to be determined according to the pressure range of the production system, the properties of the medium (such as temperature, corrosiveness, toxicity, etc.) and safety requirements. Secondly, factors such as the valve's structural form (such as spring type, heavy hammer type, etc.), sealing performance, discharge capacity, and opening and closing response time need to be considered. Only by comprehensively considering these factors can the Pressure Relief Valve that best suits production needs be selected.
In order to ensure the reliable operation of Pressure Relief Valve in chemical production, an effective maintenance strategy must be implemented. Here are some key maintenance measures:
Regular inspection and testing:
Perform visual inspection and functional testing of the Pressure Relief Valve regularly to ensure that it is leak-free, undamaged and can open and close correctly at the set pressure.
Use special test equipment to perform simulated pressure tests on the valve to verify its response time and accuracy.
Cleaning and maintenance:
Regularly clean the outside and inside of the valve to remove accumulated dirt, grease and corrosive substances.
Lubricate the moving parts of the valve to reduce friction and wear.
Replacement and repair:
Regularly check and replace aged, worn or damaged seals and wearing parts.
For parts that cannot be repaired, they should be replaced with new parts in a timely manner, and ensure that their quality and performance meet the requirements.
Record and file management:
Establish a detailed maintenance record file to record the time, content, results and maintenance personnel of each maintenance.
Manage the files of the valve, including the manufacturer's instructions, installation drawings, maintenance manuals, etc., to ensure the integrity and traceability of the files.
Training and awareness raising:
Provide professional training to operators and maintenance personnel to make them understand the working principle, maintenance methods and safe operating procedures of Pressure Relief Valve.
Strengthen the safety awareness education of operators and maintenance personnel to improve their ability to discover and report potential problems.
