The pneumatic ceramic double gate valve Z644C-10T is a top-notch expert in handling abrasive media. Especially in power plants, it has to deal with highly abrasive media such as coal powder and ore powder, but it can still maintain sealing to ensure that the media passes smoothly without leakage. Today, let’s take a closer look at how the ceramic components of Z644C-10T do this.

When dealing with abrasive media such as coal powder and ore powder, the sealing of the valve faces huge challenges. These media contain a large number of hard particles, which will cause wear on the sealing surface when passing through the valve. Over time, the sealing will decrease and the medium will leak, which will not only affect production efficiency, but also may bring safety hazards. Therefore, maintaining good sealing is the key to the stable operation of the pneumatic ceramic plate feed valve Z644C-10T in abrasive media.

The ceramic material used by Z644C-10T is the secret to its sealing. This material has extremely high hardness and wear resistance, can resist the wear of hard particles in the medium, and ensure the integrity of the sealing surface. More importantly, ceramic materials also have good self-sealing properties, and can maintain a good sealing effect even under high pressure difference and high temperature conditions. In addition, the expansion coefficient of ceramic materials is small and it is not easy to deform due to temperature changes, which further enhances the reliability of the seal.

Z644C-10T adopts a double gate design, and each gate is equipped with a ceramic sealing element. When the valve is closed, the two gates contact the ceramic sealing surface on the valve seat respectively to form a double sealing barrier. This design, even if one of the sealing surfaces is damaged, the other sealing surface can still maintain a good sealing effect, greatly improving the reliability of the valve. In addition, the double gate can also disperse the pressure of the medium on a single sealing surface, reduce wear and extend the service life of the valve.

Pneumatic drive is another major feature of Z644C-10T. It uses compressed air as a power source to drive the opening and closing of the valve. This drive method has a fast response speed and high control accuracy, which can ensure that the valve responds quickly when needed and cuts off or releases the medium flow in time. More importantly, the pneumatic drive can also provide buffer protection when the valve is subjected to unexpected impact or the medium pressure changes suddenly, reduce damage to the sealing components, and further enhance the sealing and durability of the valve.

In addition to the design factors of the valve itself, regular inspection and maintenance of the ceramic sealing components of the Z644C-10T are also important measures to maintain its sealing. This includes checking the wear of the sealing surface, replacing damaged ceramic components in time, and cleaning impurities inside the valve to prevent the accumulation of particles in the medium and affect the sealing effect. At the same time, the online monitoring system is used to monitor the working status of the valve in real time. Once an abnormality is found, measures are taken immediately to avoid medium leakage caused by reduced sealing.
