Driven by the macro economy, China's valve industry has developed rapidly in recent years. According to the statistics of China General Machinery Industry Association, in 2006 China's valve industry realized industrial output value of 72.51 billion yuan, an increase of 35.56%; sales income of 70.95 billion yuan, an increase of 33.7%; total profit of 4.533 billion yuan, an increase of 42.79%.
In the quality inspections of some provinces and cities, the reporter learned that there are some problems with the quality of the products of some small businesses. The main reason for these problems is that manufacturers are cutting corners and trying to shoddy. Although the overall level of China's valve industry has been greatly improved, but the product quality is still not stable enough, such as running, running, drip, leakage phenomenon often occurs in domestic valves. Experts reminded the majority of manufacturers that quality is still the main problem in the industry. To be invincible in the market, we must ensure the high quality of our products.
Zhejiang: Exports cut corners
Recently, the Zhejiang Inspection and Quarantine Bureau conducted a sampling inspection on a batch of 770 boxes, 71,020 valves worth 58,000 US dollars exported by a valve company in Zhejiang Province, and found that a large number of ball valves caused shell cracking due to shell cracking. Unqualified, far beyond the limit of defect rate of inspection procedures.
A non-conformity notice was issued for the Bureau and the company was asked to re-check the valves for rework. However, after the valve company said that all the pressure tests had been carried out and the non-conforming products had been removed, the Zhejiang Inspection and Quarantine Bureau sent personnel to conduct re-inspection. As a result, it was found that the defective products that failed the shell pressure test were still high. As determined by anatomy, the shells of these valves are very thin, apparently due to cutting corners. In this regard, the Inspection and Quarantine Bureau issued unqualified notices, prohibiting its export, and will further strengthen the inspection and supervision of this company.
According to statistics, in the first three quarters of 2006, Zhejiang Inspection and Quarantine Bureau found that 26 batches of export valves were unqualified, and the number exceeded 770,000 and the value of goods was more than 840,000 US dollars. Copper is an important raw material for valve products. Since 2006, due to soaring prices of raw materials such as copper and zinc, many manufacturers have tried every means to reduce costs by making profits, so they have adopted this method of cutting corners. In order to attract customers, there are also manufacturers who promise what valves the customer needs, and the quality of the products is difficult to guarantee. Unqualified valves enter the market, causing a lot of safety hazards to the user's production. This situation is worrying.
Chongqing: Pass rate of valve quality monitoring is only 35.9%
In July 2006, the Chongqing Municipal Administration for Industry and Commerce sold 30 households in 6 provinces and municipalities in Shanghai, Tianjin, Zhejiang, Hebei, Sichuan and Chongqing in 27 valve sales offices in Yuzhong District, Gaoxin District and Jiangbei District. The 53 samples were sampled and the pass rate was only 35.9%. The unqualified items found in the tests mainly include valve housing tests, seal tests, and low-pressure seal tests.
To this end, the Chongqing Municipal Administration for Industry and Commerce reminds consumers to consider the following two points in addition to considering well-known brands and price factors when purchasing valves: 1. The appearance should be smooth and smooth, and metal surfaces should be finely cast. When this type of valve is used as a shell test, the qualification rate is relatively high. Second, we should try to choose the valve seal surface roughness quality is better. In general, under the same conditions, such valves have a higher ability to withstand water pressure in order to prevent leakage and avoid accidents.
Relevant experts believe that the current domestic valve production backbone enterprises have been able to design and manufacture various valves in accordance with international standards such as ISO International Standard, DIN German Standard, and AWWA American Standard. The overall level of the industry has been greatly improved, but the quality is not yet stable. Especially in the case of rising prices of valve raw materials, the use of alternative materials to process valves is more common. If iron balls are used instead of copper balls, and copper iron stems are used instead of brass stems, the quality of the substitute materials will be inevitably degraded. Not long ago, the quality supervision departments in Taiyuan and Tianjin also conducted inspections on the valve market and found that many companies have severely disrupted the valve market in order to make profitable sales.
Experts: Valve Industry Urgently Needs to Improve Product Quality
At present, various valves produced by China's valve companies generally suffer from problems such as external leakage, internal leakage, poor appearance quality, short life span, inflexible operation, and unreliable valve electric devices and pneumatic devices. Some products are only equivalent to the last century. The level of the early 80s. With the development of the valve market at the end of the "Tenth Five-Year Plan" period, the output of valves has increased significantly. The relevant person of the valve branch of China General Machinery Industry Association believes that improving the quality of valve products is still a top priority.
Insiders pointed out that in order to have a leap forward in quality, the valve industry must vigorously adopt international standards and advanced foreign standards, strictly implement existing national standards, and reform existing products so that the updated products can reach the previous level. The international level of the 1990s. At the same time, the valve industry should take effective measures for the selection of raw materials for castings and forgings, casting processes, forging processes, and heat treatment, so that the quality of castings and forgings and the quality of appearance can reach international standards.
On the other hand, it should continue to carry out internal and external leakage research, strict mechanical processing technology, and vigorously promote new types of sealing materials, improve the accuracy of key parts of the product processing, extend product life, so that the valve "a short two leakage" phenomenon fundamentally improved.
Song Yinli, general secretary of China General Machinery Industry Association Valve Branch, stated that China is a large machinery manufacturing country, followed by the United States, Japan, and Germany, ranking fourth in the world. However, from the standpoint of independent intellectual property rights, China is also a weak country. Valves are a basic industry in the machinery industry. So far, there are more than 1,000 enterprises with an annual output value of more than 5 million yuan in China's valve industry, and more than 50 enterprises with an annual output value of over 100 million yuan. The total output value of the Chinese valve industry is about 40 billion yuan a year, and the export is about 8 billion to 9 billion yuan. The imported valves are all high-value valves, and the technical content is relatively high. The output value is also about 8 billion to 9 billion yuan. However, most of the valves exported are low-end products.
"This is not related to valve companies' concentration, product structure is irrational, and there is an excess production of medium and low-voltage products." Song Yinli said, "To change this situation as soon as possible, in addition to the company's own efforts, the effective method is through joint cooperation between enterprises. Mergers and reorganizations to achieve corporate capital expansion to further expand market share."
Song Yinli believes that as long as there is a possibility of joint ventures between enterprises, they should boldly try to use 3 to 5 years of time to create a number of production value of more than 500 million to 1 billion yuan of enterprise groups.
Looking at the domestic valve market, the valve industry has a wide range of development space. According to relevant experts' forecasts, the future market of valves will be mainly concentrated in the power industry, petrochemical industry, fertilizer, environmental protection and urban construction industries. They asserted that whoever has good technology, who has excellent quality, and who can continuously develop new products, whoever can seize the initiative and stand out in the fierce market competition.
