From the last century, "ten nine valve leak age" to the currentnumber of products exported to foreign countries, regulating valve industry in China has made great progress, technological innovation is the key. However, from the China General Machinery Industry Association regulating valves Branch data show that China's valve market every year up to 500 billion yuan turnover, of which there are more than 100 billion market by foreigncompanies occupied the valve adjustment, to change this the status quo, regulating valve through innovative technologies to improve the quality is the key. Needle Valves Ball Valve is one of the key. We should vigorously develop high-tech new products such as Oilfield Ball Valves, focusing on large-scale petrochemical, oil and gas gathering and transportation pipelines, coal liquefaction and other majorconstruction projects supporting the development of new valves,such as 80-ton ethylene plant cracking furnace and above the export pipeline supporting the use of high temperature valvesdoor, large-diameter high-pressure ball valve, ball valve of large diameter pipelines, Safety Valvesliquefied natural gas with low temperaturevalves. The new butterfly valves in which the demand is born out the sound,it can play a variety of environmental regulation in the pipeline cut off role. Butterfly valve in the structure and on the horizontal pipeconnected to the valve port (ie, the valve diameter), the valvewithin the valve port plate axis perpendicular to the valve portthrough the valve body and valve plate.BUTTERFLY VALVES The edge set of the valve plate spherical, set in the valve port with the sealing surface with the outer sphere, spherical sealing surface and form a seal with the seal line and the axis of eccentricity between the axis a, the horizontal centerline of the valve plate the valve port centerline andthe centerline of the shaft eccentricity between b, the outerspherical surface of the valve port connections and the anglebetween the center line of α, this is the butterfly valve principle. regulating valve industry in China has made great progress, technological innovation is the key.
