Ceramic Knife Gate Valve

Product overview of wear-resistant ceramic knife slag discharge gate valve:

The ceramic knife gate valve is mainly used for adjusting the flow rate and opening and closing of ash and slag in the dry ash system of thermal power plants. The valve has the advantages of good sealing performance, high temperature resistance, high compressive strength, flexible opening and closing, less ash sticking and accumulation, and long service life.

1. The main body of the movable ceramic knife gate valve is made of cast steel, 304 stainless steel and graphite sealing ring.

2. The applicable temperature is less than or equal to 400℃.

3. The nominal pressure of the actuator is 0.4-0.6MPa, and the nominal pressure of the valve is 1.0MPa.

Can also be customized according to user requirements.

Main performance specifications of wear-resistant ceramic knife-shaped slag discharge gate valve:

1. Sealing surface material: two kinds of structural ceramics or super hard surface alloy materials.

2. Using gas and solid mixed media such as coal slag and ash, the gate, valve seat and flow passage are made of structural ceramic materials, which are resistant to wear and have long service life.

3. Excellent sealing performance, and can be repaired with sealing cotton.

4. The inlet valve seat can be used as a dust scraper, which can be closed freely even in the case of falling dust.

5. The cavity structure of the valve body completely avoids the problems of jamming and dust accumulation.

6. Drive mode: manual, pneumatic and electric, etc.

The working principle of wear-resistant ceramic knife-shaped slag discharge gate valve:

The wear-resistant ceramic knife-shaped slag discharge gate valve is a kind of gate valve, and its working principle is somewhat similar to that of a gate valve. The moving direction of the gate is perpendicular to the direction of the fluid, and the medium is cut by the blade-shaped gate that can cut the fiber material.

The valve body of the wear-resistant ceramic knife-shaped slag discharge gate valve does not actually have a cavity, and the gate rises and falls in the side guide groove, and is pressed against the valve seat by the bottom lug. , O-ring sealing valve seat can be selected to achieve bidirectional sealing.
