Knife gate valve
Technical features:
1. Simple structure: The structure of knife gate valve is relatively simple, mainly composed of valve body, stem and gate, so it is easier to maintain and repair.
2. Good sealing performance: the knife gate valve has good sealing performance, which can cut off the fluid flow well and is suitable for working conditions that need to strictly control the fluid.
3. Small flow resistance: The internal flow passage of knife gate valve is relatively straight, and the flow resistance is relatively small, so it is suitable for occasions where fluid pressure loss needs to be reduced.
4. Corrosion resistance: The gate and sealing ring made of different materials can be used for knife gate valves to adapt to different working media and corrosive environments.
5. Wide application scope: Knife gate valve is suitable for controlling and cutting off various media such as liquid, gas and steam.

Precautions for use:
1. Operation specification: When operating the knife gate valve, it should be carried out according to the operation specification to avoid excessive force or improper operation, so as not to damage the valve or affect the sealing performance.
2. Regular maintenance: carry out regular maintenance on the knife gate valve, check whether the valve body, gate and seal are worn or damaged, and replace or repair it if necessary to ensure the normal operation of the valve.
3. Selection of medium: Select appropriate materials according to the nature of working medium to prevent valve failure or leakage caused by medium corrosion.
4. Anti-freezing measures: In cold areas, anti-freezing measures should be taken to prevent the gate valve from freezing and damaging the valve.
5. Valve position: When installing the knife gate valve, pay attention to the installation position of the valve to ensure its convenient operation and avoid being hit by external force.
6. Avoid over-closing: During use, avoid over-closing the gate to avoid damaging the sealing surface or blocking the gate.
7. Prevent vibration and impact: Avoid severe vibration and impact during fluid flow, which may adversely affect the knife gate valve.
