Chinese industries for metal valve, valve widely used in the production of metal valve used for hundreds of years of history, which has through improvement of structure and material, but restricted by metal material’s material conditions, can not adapt to the high abrasion, strong corrosion, such as the needs of the poor working conditions, mainly reflected in, severe leakage, short service life greatly affect the stability of the system operation. The traditional metal valve is in urgent need of material, design and manufacturing technology and other aspects of a complete overhaul.

The valve is fluid pipeline control device, its basic function is to connect or cut off the pipeline medium circulation, changing the medium circulation, change the direction of the flow medium, medium pressure and flow regulation, to protect the normal operation of pipeline equipment.

Butterfly butterfly plate installed in the pipe diameter direction. In the valve body cylindrical channel, disc shaped butterfly plate around the axis of rotation, rotation angle of 0 degrees ~90 degrees, when rotated to 90 degrees, the valve is fully open state.

Corrosion of valves, usually understood as valve metal materials in the chemical or electrochemical environment under the action of the destruction. As the "corrosion" phenomenon in metal and spontaneous interaction among the surrounding environment, therefore, how the environment around the metal with the use of isolation or more non-metallic composite materials, then become a common concern.

At present, China’s mechanical parts industry has the following main problems: first, repeated construction serious, low degree of specialization, form a scale, poor economic returns

Pneumatic technology is a professional technology to drive and control machinery with compressed air as the medium. Because of its energy-saving, pollution-free, efficient, low-cost, reliable, simple structure and other advantages, it is widely used in various machinery and production lines. In the past, the pneumatic systems and components of automobile and tractor production lines were designed, manufactured and maintained by the factories themselves.

Valve selection instructions:
1 types: according to the piping system design needs and various types of valves and installation of their own characteristics and other factors to determine the use of the valve.
2 transmission: according to the valve parameters, functions, operating requirements and field conditions, such as valve transmission mode selection. Our company can provide users with manual, electric, pneumatic, hydraulic, electromagnetic, automatic and other types of valves, users can also request matching.
3 valve material: the valve used by the use of its materials in common conditions (medium, temperature, pressure, etc.) to decide.

The pump was imported from the United States in 1999 and installed in the luning pipeline, with a discharge capacity of 1,900 cubic meters per hour, three times that of the domestic pump. The pump’s operation occupies a dominant position in the luning pipeline. The pump stopped operation due to the high temperature of the end tile, so the oil cannot be sealed, which seriously affects the crude oil supply of the long pipeline.

The current international equipment market has formed a pattern of monopolistic competition, Chinese enterprises should seize the opportunity that the west east gas pipeline project, and relying on a vast domestic market, it is possible to revitalize the savings industry, the necessary strength, and strengthen the national equipment industry.
