The Z643TC pneumatic single gate ceramic gate valve/Z644TC pneumatic double gate ceramic gate valve is used as the feed valve for the dry ash system bin pump in power plants. It can be used for high hardness granular media and can also be used for opening and closing various types of worn dry dust and steam pipelines in mining, papermaking, chemical industry, etc. The nominal pressure is 1.0MPa, and it is suitable for temperatures ≤ 150 ℃.
The sealing surface adopts a hard seal and the part in contact with the medium is made of structural ceramic material, which has extremely high chemical stability and hardness, and its service life is 510 times that of ordinary material valves. Therefore, this valve has extremely high wear resistance, corrosion resistance, and erosion resistance, as well as good insulation and small thermal expansion, which brings high economic benefits to users.
This valve has a fully flowing material port without any obstruction, and is equipped with a compressed air automatic blowing and blocking device, which reduces the occurrence of dust jamming and accumulation.
This valve adopts a high-end tough structure ceramic seal, with high mechanical strength, good wear resistance, and long service life. Compact structure that can be installed at any angle.
Structural characteristics of ceramic gate valve
1. Using a cylinder as the driving device, it directly pushes the gate up and down, with fast opening and closing speed.
2. The double gate adopts a floating connection to form a reliable one-way seal under the pressure of the medium. At the same time, the floating connection can cause the gate to rotate upward due to the lack of concentricity of the axis when opening and closing, so that the friction pattern between the gate and the valve seat is evenly distributed, and there will be no wire wear, greatly improving the service life,
3. The valve body and gate sealing surface are lined with wear-resistant ceramics, which have superior wear resistance.
4. Small size, easy to transport, install and maintain.
Working principle of ceramic gate valve
When the cylinder drives the gate down through the valve stem, the gate matches the sealing surface of the valve body, cutting off the channel and closing it; Otherwise, it is open.
Installation, use, and maintenance of ceramic gate valves
1. Before installation, the valve should be cleaned thoroughly and any defects that may have been caused during transportation should be removed.
2. Check if the markings and nameplates on the valve meet the usage requirements.
3. This valve can be installed on pipelines at any angle.
4. This valve should be fully open or fully closed during operation and cannot be used as a throttle valve, otherwise the sealing surface will be washed away, leading to accelerated wear.
5. If stored for a long time, it should be stored in a dry and ventilated room, regularly inspected to prevent rusting.
6. Prevent collision during transportation.
