What is an industrial boiler?How does an industrial boiler work?What are its main uses? Among them, the most important thing for industrial boilers is the safety valve. Today, we will give you an answer around the safety valve of industrial boilers:
Lever type boiler safety valve: The lever type safety valve is divided into two types: single lever type and double lever type.Because they act on the valve core through the gravitational moment of the lever and the heavy hammer, they are used to balance the steam pressure, also known as the heavy hammer safety valve.
The lever type safety valve is mainly composed of a valve core, a valve seat, a lever, a heavy hammer and a limit device.It uses the weight of the heavy hammer to press the valve core on the valve seat through the lever, and moves the position of the heavy hammer to change the magnitude of the gravitational moment to adjust the opening pressure of the safety valve.
This safety valve is simple in structure, easy to adjust and reliable in performance, so it is widely used in boilers.Generally, the single-lever safety valve is suitable for low-pressure boilers, and the double-lever safety valve is suitable for medium and high pressure boilers.
Spring-type boiler safety valve: The spring-type safety valve is mainly composed of valve core, valve seat, valve stem, spring, adjusting screw, etc.This kind of safety valve mainly uses the spring force to press the valve core on the valve seat.When the steam lifts the valve core, the edge of the valve core is also affected by the steam pressure, so that the entire working area suddenly increases, and the safety valve opens immediately; when the descending force is reduced, the valve core is closed at one time due to the sudden reduction of the steam force. Prevent the spool from jumping repeatedly.
The spring-type safety valve has a compact structure, small size and light weight; it has good tightness, is easy to adjust, can withstand vibration, and rarely leaks, so it is sensitive and reliable.
These are the answers to the safety valve of industrial boilers, I hope this knowledge can help you.
