Bulk cement silo Powder Butterfly valvenet work mainly show Henan oriental production tonnage bulk cement tank, sheet cement tanks and related equipment – cement metering system with cement conveyor (auger), the followingbutterfly valve of cement silo,
Cement silo works:
Powder Butterfly valve, mounted at the exit of the cement silo feed below with cement weighing hopper connected, cement weighing hopper 3-4 sensor hanging on a cement silo, equipped with adjustable speed screw conveyor below. When a computer issue feeding instructions, butterfly valve open, to cement weigh hopper Riga cement, weighing sampling. When said cement when the bucket reaches the upper material bit microcomputer issued instruction, close the butterfly valve, reads out the total weight of the hopper and the material and start screw conveyor ingredients.
With the output of the cement, weighing sensor detection value decreases, when the cement reaches the cutting bit, the cement silo butterfly will open and begin feeding. In the process of feeding, screw conveyor feeding moment before rate continue feeding until the cement reaches the material level.
The cement silo powder butterfly valve to be used for switching bins, hoppers, silos containing powders or granular materials. Processing can be applied to all powdery and granular materials, materials own gravity valve closure as well as pneumatic conveying of dry materials. Can be installed in the bottom of the hoppers, tanks, silos, spiral or other type of conveyor, as well as to connect the pneumatic conveying pipe.
The cement silo special powder butterfly valve installation and maintenance should note the following:
1, when installed, the valve flap to be parked in the closed position.
2, the open position in accordance with the butterfly plate rotation angle to determine.
3, with a bypass valve butterfly valve turned on before you turn on the bypass valve.
The installation should be carried out according to the manufacturer’s installation instructions, the weight of a large butterfly valves.
Discharge powder butterfly valve by the valve body of aluminum alloy, carbon steel valve plate, BNR rubber seals, covered with a wear-resistant polymer material processing. Manual, electric, compressed air driven gear motor driven drive device can be mutually exchanged. Compact, easy to install, sealing effect significant, long service life. In addition, I plant the production of cement silo top precipitator products quality assurance, the complete model. Has a very rich experience and unique technology in the domestic leading level. Discharge butterfly valve main advantages of simple structure, easy maintenance, small size, light weight, low cost, discharge butterfly valve This feature is particularly significant, installing underground passage at high altitude, after two five-way solenoid valve control easy to operate, can regulate the flow medium . Fluid resistance is small, medium and large caliber pneumatic butterfly valve is fully open the effective flow area, open and close rapidly and effort, dish pull rotation 90 angle to complete the hoist shaft on both sides of dish wrench media force nearly equal, contrary to the direction of the torque generated, and thus a smaller hoisting torque, low voltage can achieve a good seal, the sealing material of the disc valve with nitrile rubber, fluoro rubber, edible rubber, PTFE lining so good sealing performance, wherein the hard seal Singles valve for hard and soft cascading sheet metal heavy metal seal and elastic sealing advantages both with excellent sealing performance at low temperatures.
