Express reporter was informed that, according to refrigeration, present, about 6,000 more than the valve, which annual output value over 500 million there are 900. Domestic companies listed on the valve 3, which in nuclear science and technology, Hong Seong shares, Guangdong Pearl. Last year, the main business income of nuclear science and technology 235 million, Seong main business income of 146 million shares, the main business income of Guangdong Pearl 1.5 billion. These enterprises, regardless of its size, or quality of products, are currently unable to compete with similar foreign companies. China's valve industry, currently has 10% of the market occupied by foreign enterprises, China General Machinery Industry Association valves Branch of the stakeholders believe that to change this situation and improve the quality of the valve is the key.
Valve in the mechanical products occupy a large proportion. According to foreign industrial countries, the valve output of compressors, fans and pumps added together, the whole machinery industry output value accounted for about 5%. Meanwhile, as major technical equipment, an important component, especially in the power, petrochemical, metallurgy, urban water supply and drainage system, the valve is a key role, but the amount is very large.
Largest market for air conditioning and refrigeration, according to expert analysis, resulting in a passive valve market our country there are two main reasons: First, the valve of domestic products and imported products than there are gaps, the quality to be improved; Second, some users is not strong awareness of domestic even artificially set the threshold, so that domestic enterprises and foreign enterprises in the bidding is difficult to bid.
Refrigeration Express reporter was informed that the current production of China's enterprises widespread leakage of the valve, internal leakage, the appearance of high quality, short life, the operation is not flexible and electric valve actuators and pneumatic devices are not reliable shortcomings, some product is equivalent to the early eighties of last century the international level. Therefore, the development of industrial valves, urgent need to develop new products with high technological content.
Experts requested, the valve industry should vigorously adopt international standards and foreign advanced standards, and strictly implement the existing national standards, the reform of existing products, the updated products meet international standards nineties of last century. Meanwhile, the valve industry, selection of raw materials should Forging, casting, forging, heat treatment and other sectors to take effective measures to rough castings and forgings, including the quality and appearance quality to meet international standards.
On the other hand, should continue, the leakage of research, strict machining process, to promote new sealing materials to improve the processing precision of key parts products, extend product life of the valve 'for a short two-drain' phenomenon a fundamental turn for the better .
Looking at the domestic valve market, the valve industry has a broad space for development, experts predict, the future market, mainly in the valve power industry, petrochemical, fertilizer, environmental protection and urban construction and other industries. They assert, and who has good technology, and who has excellent quality, who can constantly develop new products, who can in the fierce market competition to seize the initiative, come to the fore.
