Maintenance and care of chemical valves

Chemical valves are an important part of the chemical pipeline system, and they play a vital role in ensuring the smooth progress of the process and the long-term stable operation of the equipment. The maintenance and care of chemical valves are elaborated in detail to improve the service life of the valves and ensure the safety and efficiency of chemical production.

Overview of chemical valves
Chemical valves are a device used to control the flow of media in pipelines, with functions such as cutoff, regulation, diversion, and backflow prevention. In the chemical production process, valves need to withstand harsh working conditions such as high temperature, pressure, and corrosion, so their maintenance and care work is particularly important.

Common valve types and their characteristics
1. Shut-off valve: used to cut off or connect the flow of media in the pipeline, with good sealing performance.
2. Regulating valve: used to adjust the flow rate, pressure excitation and other parameters of the medium in the pipeline to maintain the stability of the production process.
3. Return valve: used to prevent the backflow of media in the pipeline and protect the equipment from backflow damage.
4. Safety valve: used to automatically release pressure when the pressure in the pipeline exceeds the set value to ensure system safety.

Maintenance and care methods
1. Regular inspection: Regularly inspect the valve, including appearance, sealing performance, operational flexibility, etc., to ensure that it is in good condition.
2. Cleaning and maintenance: Regularly clean the inside of the valve and the sealing surface to remove impurities and sediments and keep the valve unobstructed.
