The safety valve is a special branch of the valve family. Its speciality is because unlike other valves, it only acts as a switch, and more importantly, it protects the safety of the equipment. With the rapid development of China's economic construction, there are more and more projects with pressure control equipment. Due to the need for equipment pressure relief, safety valves play a crucial role in protecting the equipment.
By 2013, there were more than 700 manufacturers and traders of various types of safety valves and more than 200 inquiries per day. The market for supply and demand of safety valves rose significantly. According to the preliminary analysis of the first quarter data, the demand for safety valves was 20 percentage points higher than last year. Why is the demand for safety valve market so much higher this year? The author has made an understanding and visit on this issue.
Safety valves are important safety accessories for boilers, pressure vessels and other pressurized equipment. The safety valve (also known as the pressure relief valve) is automatically opened and closed according to the working pressure (working temperature) of the pressure system, and is usually installed on the equipment or pipeline of the closed system to protect the safety of the system. When the pressure or temperature in the equipment or pipeline exceeds the set pressure of the safety valve, it will automatically open the pressure relief or reduce the temperature to ensure that the medium pressure (temperature) in the equipment and pipeline is below the set pressure (temperature) and protect the equipment and pipeline to work normally. Prevent accidents and reduce losses.
Safety valves are mainly used in steam boilers, liquefied petroleum gas vehicle tankers or liquefied petroleum gas rail tankers, oil production wells, high-pressure bypass steam power equipment, pressure piping, pressure vessels and so on. Safety valves are generally divided into spring-type safety valves, lever-type safety valves, and pulse-type safety valves according to the structure. Among them, spring-loaded safety valves are most commonly used; they are divided into thread-safety valves and flange-type safety valves. Safety valve diameter is generally not large, commonly used in DN15mm-DN80mm, more than 150mm are generally known as large-diameter safety valve.
Through the interpretation of the safety valve, I believe we have a certain understanding of this special valve. Why did the safety valve sales curve keep rising this year? The author visited the pump valve manufacturing company with the problem. The company is a representative enterprise in the safety valve industry and also occupies domestic and international high-end markets. “This year's sales of safety valve of our company compared to previous years, the first quarter almost completed the amount of tasks in the second quarter of last year. According to this year's purchase orders, it is mainly used in the safety of petroleum, petrochemical, high-temperature heat, power stations. Most of the valves are built up in the country this year, and the number of safety valve purchases has also increased. In addition, the number of safety valves exported this year has also increased compared to previous years, such as oil and natural gas extraction in the Middle East, and imports of China this year. The number of valves has also increased. These are one of the reasons that affect the sales of the safety valve market this year." Zhang Yiru, head of the company, said.
In 2013, the market size of the safety valve industry expanded year-on-year, which is an indisputable fact. According to the author's understanding, the number of companies that can now qualify for the production of safety valves in our country is not much, because safety valves belong to the special equipment industry, and the State Administration of Quality Supervision has stricter requirements for qualification review. This year, there is no doubt that the huge demand for safety valves in the market. This brings more wealth opportunities to these companies that are qualified to produce safety valves.
