‌Pneumatic PTFE knife gate valve‌ is a valve controlled by a pneumatic actuator, mainly used to cut off and regulate the flow of media. Its key components include pneumatic actuators and knife gate valve bodies, which are commonly used in various industrial fields, such as chemical, coal, sugar, sewage treatment and papermaking, etc. ‌

Structural features:

The main structural features of pneumatic PTFE knife gate valves include:

‌Pneumatic actuator‌: The upper part is the pneumatic actuator, which is responsible for providing power.

‌Knife gate valve body‌: The lower part is the valve body, including the gate, valve seat, sealing ring and other components.

‌Sealing design‌: The use of PTFE sealing rings ensures good sealing performance and prevents medium leakage.

Working principle:

The pneumatic PTFE knife gate valve controls the opening and closing of the gate through a pneumatic actuator. When the pneumatic actuator receives a signal, the gate is pushed up and down by the cylinder to realize the opening and closing of the valve. The bottom of the gate is processed into a blade shape to ensure that the medium can be cut off when closed.

Application scenario

Pneumatic PTFE knife gate valves are widely used in various industrial fields, especially in situations where high sealing and corrosion resistance are required. For example:

Chemical industry: used to transport corrosive media.

Coal: used in coal preparation, gangue discharge, slag discharge and other processes.

Sugar making: used to cut off and regulate the flow of syrup in the sugar industry.

Sewage treatment: cut off the flow of sewage during sewage treatment to ensure the treatment effect.

Maintenance and maintenance:

In order to ensure the long-term and stable operation of the pneumatic PTFE knife gate valve, regular maintenance and maintenance are required:

Lubricating oil addition: regularly add a small amount of lubricating oil to the inner wall of the cylinder to keep the cylinder running smoothly.

Inspection and maintenance: regularly check the wear of each component of the valve and replace the worn parts in time.

Debugging and maintenance: when abnormal conditions are found, debug and repair in time to ensure the normal operation of the valve.

Ceramic valves are suitable for opening and closing of pipes with high hardness particles, such as ash, slag water, pulverized coal, or soft particles but corrosive media. The sealing surface is made of high-grade toughened industrial ceramics. Its chemical stability and hardness are very high.

It has high wear resistance, corrosion resistance and erosion resistance. It also has good thermal insulation, small thermal expansion, high mechanical strength, low starting load, less ash jamming and ash deposit, and long service life Advantage.The solid valve body design can avoid valve body perforation and leakage caused by high-speed medium erosion.
