What is the difference between safety valve and ball valve?
Safety valves and ball valves are two different types of valves. Their main differences lie in their functions, applications, and working principles.
Safety valve
Working principle: The safety valve operates automatically. When the pressure in the system exceeds the predetermined safety limit, the valve will open to release the pressure to prevent the equipment or pipeline from rupturing due to excessive pressure. When the pressure returns to normal, the valve will close automatically.
Features: Mainly used to prevent excessive pressure and protect the system from overpressure damage.
Application scenarios: Commonly used in boilers, pressure vessels, pipeline systems, etc. to ensure the safe operation of equipment.
Ball valve
Working principle: The ball valve controls the flow of fluid by rotating the ball. There is a hole on the ball. When it rotates 90 degrees, the hole is aligned or perpendicular to the pipeline, thereby opening or closing the fluid channel.
Features: The ball valve has excellent sealing performance and low fluid resistance, is easy to operate, and is suitable for fast opening and closing.
Application scenarios: Suitable for fluid control systems that require frequent operation or fast opening and closing, such as water treatment, petrochemical, natural gas pipelines, etc.
In summary, the safety valve is mainly used for safety protection functions to prevent the system pressure from being too high, while the ball valve is used for simple switch control to guide or cut off the fluid flow.
