Ceramic Gate Valve

Ceramic Gate Valve

Development of Ceramic Valves 

The valves commonly used in various industries in China are metal valves. Metal valves have been used for hundreds of years. Although metal valves have undergone structural and material improvements, they cannot adapt to increasingly high wear and strong corrosion due to the limitations of metal material properties. The needs of other harsh working conditions are mainly reflected in the short service life and serious leakage, which greatly affects the stability of the system operation. Traditional metal valves are in urgent need of a complete innovation in materials, design and manufacturing processes.

The application of ceramic materials to industrial valves is a bold and beneficial innovation. 

The deformation of the ceramic material is very small.Ceramic valve has much higher bonding strength than metals. Generally, the crystal ion radius of ceramic materials is small, and the ionic electricity price is high, and the coordination number is large. These properties determine the tensile strength, compressive strength, elastic modulus of ceramic materials. The quantity and hardness are very high. However, the "brittleness" and difficult processing of the ceramic itself limit its application range. In the past ten years, due to the development and progress of martensitic transformation toughening technology, composite technology and nano-ceramic concept, the "ceramic" Brittleness" has been greatly improved, its toughness and strength have been greatly improved, and the range of applications has continued to expand.

In recent years, the application of new ceramic materials in petroleum, chemical, machinery and other fields has been very active. Using the wear resistance and corrosion resistance of ceramics to make wear-resistant and corrosion-resistant parts instead of metal materials has become an important part of the high-tech material market in recent years. one of the development directions.

The wear-resistant ceramic discharge valve is mainly used for the opening and closing of the gas and slag in the dry ash system of the power plant. For opening and closing on the side of the pipe. PG double gate air lock wear-resistant ceramic valve has good sealing performance, high temperature resistance, strong wear resistance, easy start, no sticking and ash accumulation, easy to use

Installation instructions for ceramic discharge valve:

You are welcome to choose our patented products. In order to prolong the service life and improve the work efficiency, the valve should be installed upright as far as possible. Install at 45 degrees if conditions do not allow. For example, in the case of inverted or horizontal installation, the empty delivery time must be extended to avoid valve volume ash. The valve's return signal adopts imported inductive magnetic switch two-wire system, which can be adapted to DC and AC through the load. 

Installation and use points

1. Read this instruction carefully before installation, and check the valve model, diameter and technical parameters.

2. It is strictly forbidden to weld the flange after installing the valve, so as not to damage the valve sealing ring. The valve installation distance reserved by the pipeline should be appropriate, and gaskets should be added on both sides of the flange.

3. The center of the two pipes and the center of the valve diameter should be kept coaxial, and the flange surface should be flat, and no large deflection of the flange surface is allowed to ensure the clamping and normal operation of the valve. Tighten bolts should be uniform and symmetrical.

Applications 

Ceramic discharge 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 working conditions, ceramic valve shows its excellent performance. . Ceramic valves can meet the high wear and strong corrosion environment, especially the outstanding feature is the long service life, the cost performance of ceramic valves is better than other similar metal valves. With the continuous development and progress of science and technology, the technology of ceramic materials in terms of formula, molding, processing and assembly technology has become more mature and complete, and ceramic valves are increasingly recognized by the valve industry for their excellent performance. Using the successful experience of manufacturing ceramic valves can also be applied to a wider range of engineering fields.
