Widely used in the production of various industries Chinese valve metal valves, metal valves for use has been a century of history, during which although improved through structure and materials, but the metal itself material conditions, more can not adapt to high wear, corrosion and other harsh conditions strong demand, mainly reflected in the use of short life, a serious leak, which greatly affects the system stability。 Traditional metal valve urgent need from materials, design and manufacturing processes and other aspects of innovation。
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 which uses compressed air as medium to drive and control machinery。 Because of its energy saving, pollution-free, high efficiency, low cost, safe and reliable, simple structure and other advantages, widely used in various machinery and production lines。 In the past, the pneumatic system and its components on automobile, tractor and other production lines were designed, manufactured and maintained by each factory。
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 is a pipeline company in 1999 from the United States imported and installed in Lu Ning pipeline, the transmission capacity of 1900 cubic meters per hour, 3 times the amount of domestic oil pump is exhausted, the operation of the pump to occupy a dominant position in Lu Ning pipeline. Because the temperature of the end tile is too high to stop running, the oil transportation can not be carried out.
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.
