The author understands that the valve is a control component in the pipeline transportation system, which can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. In the pharmaceutical industry, the use of valves is large and plays a large role.
It is reported that there are more than 3,000 valve manufacturing enterprises in China, which can produce gate valves, throttle valves, ball valves, globe valves, butterfly valves, diaphragm valves, control methods, etc., to meet the requirements and needs of various fields.
In terms of control valve ranks, at present, domestic control valve manufacturers are mainly concentrated in Zhejiang, Jiangsu and Shanghai. According to relevant information, in 2017, there were 6 geographical distributions of enterprises in China's top control valve manufacturers, 4 in Jiangsu, and 6 in Shanghai.
At present, domestic control valves use pressures up to 2,500 pounds and use temperatures up to 1200 °C. Control valves used in industrial systems except for power, petrochemical, metallurgical, nuclear power and other key parts of the high temperature, high pressure, high wear and other key parts of the control valve need to be imported, the rest of the products of China's control valve enterprises can basically produce and manufacture.
In recent years, China's control valve manufacturers have also provided some nuclear control valves for a number of nuclear power plant units. The proportion of imported control valves required for industrial enterprises in China has been decreasing year by year. At the same time, the control valve products produced by some domestic enterprises have been followed. The project is supporting exports.
It can be seen that China's valve technology is constantly improving, and automation and intelligent products are gradually occupying the market. Some manufacturers said that many companies are striving to give intelligent technology to valves, and valves with intelligent features have many advantages.
For example, it can identify the valve body, actuator and diaphragm information; can identify product information and survival information; can improve the reliability of the process through the traceability of information; can establish work-specific electronic documents (such as certification documents); Maintenance log, optimized maintenance process; can also enhance the intelligence of the instrumentation (installation qualification); also can carry out paperless office and maintenance.
Although China's valve industry has improved in terms of quality and technical level, many products still have some shortcomings. The market is still dominated by international advanced enterprises, and the share of valve enterprises in China is relatively low. But analysts also pointed out that this also means that China's valve industry still has huge market development potential, and enterprises need to seize opportunities.
The author understands that some companies are actively formulating standards and mastering powerful market-strengthening tools. For example, the pump and valve enterprises in Yongjia County, relevant persons said that enterprises actively participate in the formulation of standards, so that Yongjia Valve occupies a large part of the industry's right to speak, and participation in the formulation of standards is a "additional item" in many bidding projects.
Therefore, the enthusiasm of the company is very high. At the same time, with the development of quality control and related brand certification work, the number of Yongjia valve enterprises participating in the formulation of standards will reach a new high.
Some regions have also introduced relevant programs, and proposed six projects including the implementation of innovation capability enhancement, brand standard enhancement, information technology transformation, leading enterprise cultivation, platform investment promotion, and green development* action, in order to further increase policy support and strengthen policies. Reverse the mechanism to create a strong atmosphere for the revitalization of the valve industry.
In industrial manufacturing or life, you will see many brass parts, most of which are made by investment casting. For example, many accessories such as brass jewelry, brass pendants, brass ornaments and so on that are common in our lives are produced by investment casting. The casting performance of brass in copper alloys is relatively good, but its shrinkage is relatively large, and it is prone to shrinkage holes, cold cracks, deformation and other problems. It is necessary to reduce the pouring temperature as much as possible in the actual pouring to improve this problem. Of course, there are many other processes to improve this shortcoming, such as selecting a good sand mold, setting a riser, or setting a gating system, etc., which can be improved, and the details are discussed and analyzed according to the structure of the workpiece.
Brass casting is not only used in jewelry, pendants, ornaments and other handicrafts in daily life, but also widely used in industry, because copper itself has good corrosion resistance and superior conductivity. There are also many brass castings produced by SCZY. The common ones are some handicrafts, some architectural accessories, and auto accessories. We also support secondary precision CNC machining and surface treatment. Let customers have no worries.
