Only county-valve on the more than 3,000 of over 300 specifications, widely used in large state-owned enterprises and key projects of technology and equipment. At the same time, the valve on a high technical requirements, while domestic enterprises currently produce widespread leakage in the valve leakage, the appearance of high-quality, short life, not flexible operation of electric and pneumatic valves and devices, such as unreliable shortcomings, some products Only at the beginning of the 1980s, the international standard. Experts predict that the future growth of the valve market, mainly in electricity, petrochemicals, fertilizers, environmental protection and other fields, the valve business, who has good technology and high quality, who can constantly develop new products, who will be in fierce Qiangde advantage in the competition.
Experts suggested that we should upgrade the quality of valves, must be in production management, technology, new product development on. First of all to strengthen management. Production and technology management as soon as possible with international practice, accelerate the adoption of international standards and the pace of foreign advanced standards, increase investment, introduction of modern, automated equipment, the existing product innovation. At the same time, enterprises should Zhu Duanjian valve of raw materials selection,brass ball valve casting and forging process, heat treatment, and other areas to take effective measures to Zhu Duanjian rough, in terms of quality and appearance of international standard. Second, we should vigorously brass ball valve develop new high-tech content. Experts predict that the "11th Five-Year Plan" period, with petrochemical valves focused on the development of large-scale petrochemical industry, oil and natural gas gathering and transportation pipelines, coal liquefaction and other major construction projects supporting the development of new valves, such as the 800,000-ton ethylene and above Cracking Furnace devices supporting the export pipeline with high-temperature valves, large-diameter high-pressure valve, large-diameter pipeline valve, low-temperature liquefied natural gas valves, and other needs will be greater growth in the valve industry is expected to "11th Five-Year Plan" demand The total will reach 34.5 billion yuan. Again, should be strengthened within and outside the valve leakage research, strictly mechanical processing technology, and vigorously promote the development of new sealing materials, improve product key component of precision machining, to extend product life, so that the brass ball valve valve, "a short two leakage" phenomenon fundamentally improved.
