What are the commonly used valves in oil refining equipment?

In oil refining plants, fluid control is a key link to ensure production safety and efficiency. Different process flows and operating conditions have specific requirements for valve types. The following are several commonly used valve types and their applications in oil refining plants:

1. Gate valve
Gate valve is one of the most common valves in oil refining plants and is widely used for opening and closing pipelines. It is characterized by low fluid resistance, labor-saving switching, and is suitable for high pressure and high temperature environments. Gate valves are often used in pipeline systems for transporting oil and natural gas, as well as for cutting off or connecting fluid channels.

2. Check valve
Check valves are used to prevent fluid backflow and protect equipment and pipelines from damage. In oil refining plants, check valves are often installed at the outlet of the pump to prevent fluid backflow and damage to the pump when the pump stops running.

3. Butterfly valve
Butterfly valves have a simple structure, small size, and light weight. They are widely used in large-diameter pipelines to cut off or regulate fluids. In oil refining plants, butterfly valves are often used in cooling water systems, air systems, etc., and have the characteristics of rapid switching and convenient maintenance.

There are various types of valves in oil refining plants, and each valve has its specific functions and applications. Reasonable selection and configuration of valves can not only improve production efficiency, but also effectively ensure production safety and avoid accidents.
