MKZ941H mining electric gate valve has excellent wear resistance and corrosion resistance performance
Date: 2025-12-14Read: 20
MKZ941H mining electric gate valve is a type of high reliability electric actuator control valve designed for complex working conditions underground in mines. It is commonly used in water supply and drainage systems, gas extraction pipelines, mud transportation, ventilation pipelines, and underground fire water supply networks in industries such as coal mines, metal mines, and non-metallic mines. This model of valve adopts an electric actuator to drive the wedge gate, which has the characteristics of flexible opening and closing, good sealing performance, strong pressure resistance, and convenient remote automatic control. It is one of the key equipment in mining automation water and gas systems.
The actuator has the following characteristics:
1. High opening and closing force: can reliably open and close under high pressure conditions;
2. Precise stroke control: using mechanical and electronic dual limit to avoid damage to the valve due to overtravel;
3. Remote/Local Control Conversion: Compatible with PLC and DCS systems to achieve automated monitoring;
4. Complete feedback signal: equipped with valve position feedback, operating current feedback, and fault alarm functions.
MKZ941H mining electric gate valvePerformance advantages:
1. High reliability explosion-proof
In areas with unstable gas concentration in mines, it can effectively prevent explosions caused by electric sparks and improve the safety of underground equipment operation.
2. Excellent sealing performance
Wedge gate combined with metal hard seal can maintain tight closure in high-pressure and high flow rate situations, making it less prone to leakage.
3. Adapt to harsh working conditions
The valve body and sealing pair have excellent wear resistance and corrosion resistance, and are suitable for harsh working conditions such as granular media, such as slurry and sand water.
4. High degree of automation
It can be remotely controlled for opening and closing, achieve centralized monitoring, and be linked with the comprehensive automation system of the mine to improve operational efficiency.
5. Easy maintenance
The structure is relatively simple, and the valve stem seal adopts graphite packing or combination seal, which is easy to maintain and has a long service life.
Application scenarios of MKZ941H mining electric gate valve:
1. Main drainage system of the mine: Cut off or switch the high-pressure water supply pipeline;
2. Gas extraction system: used for opening and closing control of gas pipelines to ensure safe extraction;
3. Underground fire water system: linked with automatic sprinkler or spray system;
4. Ore transportation associated water system: control the flow of sand containing water or mud;
5. Supporting purposes for main and auxiliary ventilation systems (such as electric air door and water seal systems);
6. Mineral processing plant and ground pump room: transporting clean water, sewage, and chemical media.
