With the progress of science and technology, in machinery manufacturing, power, construction, transportation, information technology and other fields, machinery and equipment or production process has been able to achieve measurement, operation and other information processing and process control according to the expected goal without direct manual intervention, and has gradually realized industrial automation, and the corresponding industrial automation technology has become to improve labor The main means of productivity. The control valve is used to adjust the flow rate of the control variable, therefore, formerly known as the control valve. From the control system as a whole, whether a control system can be controlled well or not depends on the regulating valve. It can be said that the control valve is equivalent to the brain center of a machine system, which controls the normal operation of the whole set of machinery. It plays an extremely important role in the current social and economic development.
The application range of control valve is also extremely wide, including metallurgy, petrochemical, hydropower, large machinery, as long as it involves mechanical aspects, there are regulating valves. In the application of modern nuclear power, the control valve industry is playing an increasingly important role. Nuclear power control valve is the process equipment and control equipment of nuclear power plant operation, which plays an extremely important role in the normal, safe and stable operation of nuclear power plant. At present, only a few multinational companies such as IMI group have production capacity.
Recently, a company in Shanghai has cooperated with foreign countries to establish a joint venture. The newly established company will mainly engage in the processing, design and production of key nuclear control valves, provide key nuclear control valves for the target market, and fill the gap in the key field of nuclear power control valves of Shanghai Electric and even China. It is reported that the joint venture has an investment of 40 million yuan. After being put into operation, the joint venture can realize the localization of key nuclear power control valves, reduce the construction cost of nuclear power projects and break the monopoly of foreign technology. It can provide nearly 100 sets of nuclear power system devices and tens of thousands of nuclear power instruments for all commercial nuclear power plants in China, and is also a qualified supplier of all commercial nuclear power plants (including export projects).
The biggest characteristic of the control valve is that it can work in the place without electricity and gas, and at the same time, it can save energy. The pressure setting value can be adjusted at will during operation. It is widely used in petroleum, chemical, electric power, metallurgy, food, textile, machinery manufacturing and residential buildings and other industrial equipment. In the future, it will play a more important role and has a broad prospect.
