Safety Valves - Basic Knowledge

1、 Overview of the Safety Valve

The safety valve is normally closed under the action of external force on the opening and closing parts. When the medium pressure in the equipment or pipeline rises above the specified value, the medium is discharged to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value.

Safety valves belong to the category of automatic valves, which are mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value and it plays an important role in protecting the personal safety and equipment. The safety valve must be pressure tested before it can be used.

With the rapid development of China’s economic construction, there are more and more equipment projects with pressure control. In view of the need for equipment to reieve pressure, safety valves play a vital role in protecting the equipment. As of 2013, there have been more than 700 various safety valve manufacturers and traders, with more than 200 daily transaction inquiries, and the supply and demand market for safety valves has obviously heated up.

Safety valves are mainly used in: steam boilers, liquefied petroleum gas tank cars or liquefied petroleum gas railway tank cars, oil production wells, high-pressure bypasses of steam power generation equipment, pressure pipes, pressure vessels, etc.

2、 Types of Safety Valves

The diameter of the safety valve is generally not large. The commonly used ones are between DN15mm-DN80mm, and those over 150mm are generally called large-diameter safety valves.

Safety valves are divided into full swing safety valves and macro opening safety valves. According to the overall structure and loading mode of the safety valve, it can be divided into four types: deadweight, lever, spring and pilot. According to the connection with the pipeline, it can be divided into threaded safety valve and flange safety valve.
