The valve enterprise still should take effort

Our country at present the China Valve industry has about 10% of the market by foreign enterprise occupation, and the Chinese general machinery industry association of related people think valve branch, want to change this kind of situation, improve the quality of the valve is the key.

The valve in the mechanical product occupies a large proportion. According to foreign industrial developed country statistics, output alue of valve is compressor, fan and pump the sum of the three, accounting for about 5% of the mechanical industrial output. At the same time, as a major technology is an important part of the equipment, especially in electric power, petrochemical, metallurgical, city water supply and drainage system, the valve is to play a key role, and dosage is very big.

At present, China valve 6000 enterprises, of which more than 5 million yuan in output alue 900 homes. The valves in domestic market, that is, three in nuclear technology, HongCheng shares, guangdong pearl. Last year, the nuclear technology in the main business income is 235 million yuan, HongCheng shares main business income is 146 million yuan, guangdong pearl's main business income is 150 million yuan. The enterprise, whether its size, or product quality, are unable to compete with the similar foreign enterprise.

Analysis of the personage inside course of our country at present, causing the cause of the passive valve market basically has two aspects: one is domestic and imported goods valve products than and difference, quality to be raised; 2 it is some users localization is not strong, and even human consciousness to set the threshold, make domestic enterprise with foreign enterprises to the winning bidders.

Concerned expert thinks, the enterprises in China's current production of a common valve leakage, leakage, exterior quality is not high, short life, not flexible operating valves and electric device and pneumatic devices unreliable shortcomings, some products, only the equivalent of the beginning of the eighty s, the international standard. Therefore, the development of the Hydrant Valve industry, to develop the new products with high technical content.

Concerned expert requirements, the Hydrant Valve industry should vigorously adopt international standards and foreign advanced standard, strictly implement the existing national standards, to existing products by reform, the updated products to ninety s of the last century international level. At the same time, the valve industry cope with castings and forgings of material selection, casting process, forging process, heat treatment and other link take effective measures, make castings and forgings blank, quality and appearance in quality achieved the international level.

On the other hand, should continue to carry out internal and external leakage research, strict mechanical processing technology, to promote new type sealing material, improve product key parts of the machining precision and extend the service life of the product, so that the valve "a short two leakage" phenomenon fundamentally improved.
