First, use
The valve for the raw material mill feed lock wind special equipment
Second, the structural characteristics
1. Pneumatic valve than the structure of the electric valve is more
compact, a corresponding reduction in parts, to the maintenance work is
very convenient;
2. Work basically no noise;
3. Cylinder part of the German Festo cylinder, with the use of reliable, long life and other characteristics;
4. The valve plate surface is made of high wear-resistant electrode
surfacing, making the life of the valve plate nearly 5 times;
5. The valve does not use the spring reset form, nor the use of heavy hammer-type reset, so the site safety factor is high.
Third, the operating conditions
Temperature: ≤350 ° C
Bottom of the negative pressure: -30 ~ -50mmH2O
Feed moisture: ≤ 5%
Feeding size: ≤ 20mm
Fourth, technical performance
1. Throughput: 700t / h
2. Opening and closing times: 12-15 times / min
3. Cylinder technical performance
4. Cylinder operating frequency: 12 to 15 times / min
5. Cylinder action control using a small PLC, on-site self-distribution control box
6. On-site electrical control box should have an alarm function, and
connected to the central control room, central control room with a
hearing function
7. A cylinder of 0.6MPa for each round-trip air pressure is 0.0063m3, or 6 ,. 3 liters
