China's valve industry development situation is grim

May 09, 2018

Understands from China general machinery industry association branch valve, China valve market turnover of up to 50 billion yuan a year, but has more than 100 one hundred million yuan market was occupied by foreign enterprises valve. They think that to change the status quo, improve the quality of the valve is the key. The valve in the mechanical product occupies a considerable proportion. According to foreign developed countries, the valve output is the sum of compressor, fan and pump, accounts for about 5% of the whole machinery industrial production. At the same time, as an important part of major technical equipment, especially in electric power, petrochemical, metallurgy, urban water supply and drainage system, the valve is plays a key role, and the dosage is very large. At present, the valve more than about 6000 enterprises, of which more than 5 million yuan output value of 900. Domestic listed valves 3, that is, in the nuclear science and technology, hongseong shares, guangdong pearl. Last year, the nuclear science and technology in the main business income is 235 million yuan, the main business income is 146 million yuan, hongseong shares guangdong pearl main business income is 150 million yuan. These companies, whether its size, or the quality of our products are currently unable to compete with foreign similar enterprises.
The personage inside course of study analysis, the causes of current passive valve market in China mainly has two aspects: one is the domestic valve products and imported products than there are gaps, quality improvement; Second, some user localization consciousness is not strong, even artificially set threshold, make domestic enterprises with foreign enterprises in to the winning bid.
Concerned expert thinks, our country enterprise at present the production of a common valve leakage, leakage, appearance quality is not high, short life, and not flexible operating valve electric device and pneumatic devices such unreliable shortcomings, partial product is the size of the last century in the early eighty s the international level. Therefore, the development of the valve industry, need to develop high technical content of new products.
Relevant experts, the valve industry should be vigorously adopt international standards and advanced foreign standards, strictly implement the existing national standards, to reform the existing products, make the updated products in the ninety s, the international level. Dealing with castings and forgings at the same time, the valve industry raw materials selection, casting, forging process, heat treatment to take effective measures to make the casting blank, in quality and appearance quality has reached the international level. On the other hand, should continue to carry out internal and external leakage, strict mechanical processing technology, vigorously promote new sealing material, improve the processing precision of key parts of the products, prolong the service life of product, make a short two valve leakage phenomenon fundamentally improved.
Throughout the domestic market, the valve industry has a broad development space, according to experts predict that the valve in the future market mainly in the power industry, petrochemical industry, fertilizer industry, environment protection and urban construction, etc. Who assert that they have good technology, who have high quality, who can constantly develop new products, who can force in the incentive market competition, stand out.
