Steam traps have great development potential, energy saving innovation and win the market. Compared with foreign advanced countries, the development of steam traps in China starts relatively late. In China, they are mainly used to produce medium and low pressure steam traps, with low parameters, poor performance, short service life and poor test methods. Only a few manufacturers have performance test devices for products below medium pressure, and even some steam trap manufacturers do not test at all The steam leakage of drain valve is serious.

At present, with the rapid development of information technology, steam trap, as the executive mechanism of removing condensate from steam pipeline, if modern computer technology, sensor technology, network and remote control technology and intelligent technology can be implanted into steam trap products to control the opening and closing of steam trap, a new steam trap designed according to this idea has been reported abroad. In terms of production and demand of steam traps, the gap between domestic and foreign countries is also very large. Only taking Japan as an example, energy consumption in Japan and China is similar (nearly 1 billion tons of standard coal in China, and 0.5 billion tons of standard coal in Japan). The annual output of Japan's steam traps is 3.1 million, each with a service life of more than one year, steam leakage rate of less than 3%, steam pipe network and thermal efficiency of more than 50%; while in China, steam drainage The annual output of water valves is about 2.2 million, and the average service life of each valve is less than one year. Generally, the steam leakage rate is about 6%, and the heat dissipation efficiency of steam pipes is about 30%.

At present, the steam traps in China can not meet the needs of the domestic market in terms of output, quality and product variety, and there is a big gap in the variety series of high parameter products. Based on the current situation of steam trap industry, experts in the industry put forward a new idea of technology development, that is, humanization, application of new materials, and Realization of mechatronics.

High efficiency, energy saving and green environmental protection are the main direction of China's national economic development in the future. With the large-scale electric power (power connection, thermal power, hydropower, wind power), petrochemical and metallurgical equipment, the requirements for steam traps are also increased. The working pressure of steam traps is required to reach 15.0mpa or higher, and the nominal size is up to DN150mm or greater.

Therefore, in the development of new products of steam traps, we should consider people-oriented and establish a humanized product design concept; apply new materials to steam traps continuously; integrate information technology and artificial intelligence technology into steam traps to realize mechanical and electrical integration, which is a new way of technological innovation. There are many kinds of steam traps with great differences. The market demand is constantly changing. The production scale and technical level of manufacturers of steam traps are uneven. However, the general development trend and development technical approaches of steam traps have many similarities. As long as the manufacturers of steam traps can effectively and clearly understand the current situation of the industry and constantly strengthen the optimization of their own production Products, strengthen the sense of suffering, strengthen the corporate culture and market service concept. Only by achieving stability, speed, refinement and stability, can enterprises survive and develop in the increasingly competitive industry tide.
