(Summary description)New ceramic materials are widely used in petroleum, chemical industry, machinery, solar energy, medical equipment and other fields. Shanghai chuannai's engineers use the wear resistance and corrosion resistance of ceramics to make wear-resistant and corrosion-resistant parts instead of the metal vulnerable and grindable materials inside the valves, and produce ceramic ball valves, stainless steel ceramic ball valves, gate valves, etc. Widely praised by users!

Installation and structural features of ceramic valve:

1. The ceramic ball valve adopts high-tech new ceramic structural materials to make the sealing parts and vulnerable parts of the valve, which improves the wear resistance, corrosion resistance and sealing performance of the valve products, and greatly extends the service life of the valve.

2. The use of ceramic ball valve can greatly reduce the number of valve maintenance and replacement, improve the safety and stability of supporting equipment operation system, and save equipment repair costs.

3. The use of ceramic valve can improve the tightness of industrial pipeline system, minimize leakage and protect the environment.

4. Ceramic materials are widely used with low cost. Ceramic materials with superior performance can be made by using ordinary elements such as aluminum, carbon and silicon, which can save a lot of metal materials and rare mineral resources.

Wear resistant ceramic ball valve is mainly used in electric power, petroleum, chemical industry, metallurgy, mining, sewage treatment and other industrial fields, especially in the face of high wear, strong corrosion, high temperature, high pressure and other harsh conditions, ceramic valve shows its excellent performance. Ceramic valve can meet the high wear, strong corrosion environment, especially the outstanding feature is long service life, the performance price ratio of ceramic valve is far better than other similar metal ball valve. With the continuous development and progress of science and technology, ceramic materials from the formula, molding, processing and assembly technology and other aspects of technology more mature and complete, ceramic valve with its excellent performance is more and more recognized by the valve industry. The successful experience of ceramic valve manufacturing can also be used in a wider range of engineering fields.

In the transportation of silicon powder, the ball is easy to be wrapped by silicon powder, and it is easy to damage the metal seal when it is opened frequently, which leads to leakage and other problems. Due to the high hardness of silicon powder, the service life of general ball valves is very short.

Ceramic ball valve

Chuannai valve company, a manufacturer of ceramic ball valve, has specially researched and developed a suitable ceramic ball valve for silicon powder transportation. By using the strong corrosion resistance of structural ceramics and the high corrosion resistance material of zirconium alloy, the service life of the new ball valve is 6 times longer than that of the original valve, which brings an exciting good news to the equipment management of solar polysilicon powder transportation!

Performance characteristics:

1. All the parts in contact with the medium are structural ceramic materials, which have high chemical stability and hardness (Rockwell hardness hrc90), second only to diamond. Therefore,

The valve has high wear resistance, corrosion resistance, erosion resistance, good heat insulation and small thermal expansion.

2. The ball is manufactured by advanced grinding equipment and technology, with high roundness precision and good surface quality. After lapping with the valve seat, good sealing performance can be achieved by using the self lubricity of Zr02 ceramic.

3. The defects of metal hard sealing ball valve, such as easy leakage, large torque and non corrosion resistance of sealing surface, are completely changed.

4. Ceramic good wear resistance, so that the valve durable, high reliability. Long service life, is titanium alloy valve and Monel valve 2-4 times.

5. It is used in the medium of high hardness particles, or the medium with soft particles but corrosion. The valve has incomparable absolute advantage and is the only valve suitable for this kind of medium at present.
