The developing course of turbine butterfly pneumatic valve flange ceramics

used to industries in our country commonly used for metal pneumatic valve pneumatic valve, metal pneumatic valve used for hundreds of years of history, although the metal pneumatic valve through improvement of structure and material, but restricted by metal material properties, can not adapt to more and more high wear, strong corrosive condition of demand, mainly reflected in the short service life, leaked seriously affect the stability of the system operation greatly. Traditional metal pneumatic valve need from aspects such as material, design and manufacturing process of overhaul. The ceramic material application in industrial pneumatic valve is a bold and useful innovation. Ceramic material deformation is small, has a much higher bonding strength than the metal, usually composed of ceramic material of crystal ionic radius is small, and ion electricity price is high, the coordination number is large, these properties determine the ceramic material of tensile strength, compressive strength, elastic modulus, hardness is very high. Ceramic itself, however, 'brittle' and difficult processing limits its scope of application of recent decades, due to the martensitic phase transformation toughening technology, composite material science and technology development and progress of the concept of nanometer ceramics made of pottery and porcelain 'brittle' has been greatly improved, the toughness and strength has been greatly improved, expanding application range. In recent years, new ceramic material application in the field of petroleum, chemical industry, machinery and so on are very active, the use of ceramic wear resistance, corrosion resistance, wear resistance and corrosion parts made of instead of metal materials, high-tech materials in recent years, is one of the important development direction of the market.
ceramic adjust the invention of the pneumatic valve and widely used is a case in point.
. Regulating pneumatic valve adopts high technology new ceramic structure materials pneumatic valve sealing parts and wear parts, improve the wear resistance, anticorrosion and sealing pneumatic valve products, greatly extend the service life of the pneumatic valve.
. Ceramic regulating the use of pneumatic valve can reduce the maintenance of the pneumatic valve replacement times, improve equipment operation system security, stability, cut down the cost of equipment repair.
. Ceramic regulating the use of pneumatic valve can improve the sealing of industrial piping system, can maximum limit reduce leaking, so as to protect the environment.
. Manufacturing of ceramic raw materials widely, low cost, with aluminum, carbon, silicon and other common elements can produce superior performance of the ceramic material, can save a large amount of metal materials and rare mineral resources.
wear-resisting ceramics pneumatic valve is mainly used in electric power, petroleum, chemical industry, metallurgy, mining, sewage treatment and other industrial fields, especially in the face of strong high wear and corrosion, high temperature and high pressure condition, ceramic pneumatic valve more show its excellent performance. Ceramic pneumatic valve can satisfy the use of strong high wear and corrosion environment, especially outstanding characteristic is super long service life, ceramic pneumatic valve performance is much better than the other similar metal pneumatic valves. With the continuous development and progress of science and technology, ceramic material from the formula, molding, machining and assembly process and so on various aspects of technology is more mature and complete, ceramic pneumatic valve with its superior performance, the more of the pneumatic valve industry recognition. Using the successful experience of manufacturing ceramic pneumatic valve can also be applied to a wider range of engineering fields.

performance advantage in pieces of ceramic butterfly pneumatic valve adopts eccentric structure, reduce friction moving parts;
mixer compact structure, small volume, light weight, flexible operation, opening and closing torque, energy saving and energy saving.
mixer is suitable for the relatively poor working conditions, low cost, long service life, high cost performance;
mixer has excellent corrosion resistance, high temperature resistance, wear resistance, erosion resistance, anti magnetic and antistatic, etc.
according to different working condition, tie-in and different materials of pneumatic valve components.
in pieces with different driving mode such as manual, pneumatic, electric, models complete, meet the different needs of customers;
mixer applicability is wide and in hard particles can reflect the superiority of it, more steel manufacturing, mining and other industries is the best.

application along with the development of basic construction in China, national large-scale implementation project construction, make the electric power, petroleum, chemical industry, the number of city supply and drainage system and pneumatic valve is increasing, especially adjusting the dosage of the pneumatic valve is very big, especially the application of new ceramic materials, make ceramic regulation of corrosion resistance, high temperature resistance, wear resistance, erosion resistance, anti magnetic and antistatic properties and so on have very big breakthrough, more adapt to bad working condition and working environment, therefore, its high cost performance advantages will greatly extend ceramic adjust the application range of pneumatic valve, can be widely used in petrochemical, metallurgy, paper making, power stations, oil, coal and other industries of various types of gas, liquid, steam, acid and alkali salt mud and ash conveying system to adjust the flow or cut off the medium.
note
installation and maintenance in the installation, pneumatic valve disc should be parked in the closed position;
open position should be according to the butterfly plate to determine the Angle of rotation;
with the vent valve the pneumatic butterfly valve, open open side ventilation should be taken before move valve;
should be in accordance with the manufacturer's installation instructions for installation, big weight the pneumatic butterfly valve, should set up a solid foundation.
