Multi performance electric explosion-proof flange gate valve

Multi performance electric explosion-proof flange gate valveIt is an intelligent integrated non-invasive electric valve that is connected by a multi turn intelligent integrated non-invasive electric actuator and a cast steel valve body, and is installed and debugged. The intelligent integrated non-invasive electric gate valve uses electrical energy as power to connect the electric actuator to drive the valve, achieving the opening and adjusting actions of the valve. Valves have the characteristics of simple structure and reliable operation, but due to their direct contact with process media, their performance directly affects system quality and environmental pollution. Therefore, pneumatic control valves must be regularly maintained and inspected, especially in harsh and important situations where maintenance work should be emphasized.

Features:
1. The middle flange bolt connection is adopted, and the two ends of the branch pipe are flange connection structures.
2. The sealing surface of the valve seat is welded with iron-based chromium nickel stainless steel, which has good wear resistance and abrasion resistance.
3. The surface of the valve stem is treated with corrosion-resistant nitriding, which has good corrosion resistance and abrasion resistance.
4. The closing and opening of the electric high-pressure gate valve are controlled by an electric device installed on the valve cover. The electric devices are equipped with valve motors, gearboxes, torque control mechanisms, stroke control mechanisms, on-site operating mechanisms, and manual and electric switching mechanisms. The opening and closing of the valve are adjusted by the stroke control mechanism, and the torque limiting mechanism is adjusted to protect the valve in the event of a failure of the stroke control mechanism. The electric welding gate valve is mainly closed by an electric device and adjustable wedge-shaped double gate, universal top, clamp ring, etc., which are guided by the valve body for lifting and lowering movement.
5. Electric devices can not only be operated locally, but also remotely.

Multi performance electric explosion-proof flange gate valveStandard:
1. Design and manufacture according to GB12234-89
2. The structural length shall be in accordance with GB12221-89
3. The flange size shall be in accordance with JB/T79-94
4. Valve inspection and testing shall be conducted in accordance with GB13927

In addition to paying attention to pipeline parameters, special attention should also be paid to the working environmental conditions of electric gate valves, because the electric device in electric gate valves is an electromechanical equipment, and its working condition is greatly affected by its working environment.Under normal circumstances, electric gate valves operate in the following environments:

1. Indoor installation or outdoor use with protective measures;

2. Outdoor outdoor installation, subject to erosion from wind, sand, rain, dew, sunlight, etc;

3. Having environments with flammable, explosive gases or dust;

4. Environment in humid and dry tropical regions;

5. The temperature of the pipeline medium is above 480 ℃;

6. The ambient temperature is below -20 ℃;

7. Easy to be submerged or submerged in water;

8. Environment containing radioactive materials (nuclear power plants and radioactive material testing devices);
