Boiler valves can be classified into several types based on their design and application, primarily including:
1. Spring-loaded boiler valves
Spring-loaded safety valves are the most common type. The opening pressure is set by adjusting the compression of the spring. This type of safety valve has a simple structure, is easy to adjust, and is suitable for various boiler systems.
2. Pilot-operated boiler valves
Pilot-operated safety valves control the opening and closing of the main valve through a pilot valve. They have high sensitivity and accuracy and are suitable for high-pressure, high-flow-rate boiler systems.
3. Lever-type boiler valves
Lever-type safety valves utilize the lever principle, controlling the opening pressure by adjusting the position of the counterweight. This type of safety valve has a more complex structure and is mainly used in large industrial boilers.
