Butterfly valve use in cement silo mixing station equipment

2016-07-05

Summary: butterfly valves are used in many components in concrete batching plant, especially in cement silo (cement).
Butterfly valve called flap valve, is a simple structure of the control valve, and can also be used for low pressure pipes.

Multiple components in the concrete mixing plant used on valves, especially in cement silo (cement). Butterfly valve called flap valve, is a simple structure of the control valve, but also can be used to switch control of low pressure pipeline medium. Butterfly valve is closed (disc or disc plate) disc, rotation around the axle of the valve opening and closing a valve to achieve, mainly used for cutting off and throttling in the line.



Cement silo (cement) principle of the butterfly valve: in cement silo (cement tanks) equipped with feeding butterfly valve at the outlet, and connected with cement-weighting system, cement-weighting by 3-4 sensors hanging on the cement silo, the screw conveyor with adjustable speed.

When the computer sends instructions, butterfly valve opens, add cement into cement weighing hopper and weigh. when cement reached material level in the bucket, computer send instructions, close the valve, read the total weight of the item, and start the screw conveyor ingredients.



With the output of cement, weighing sensor detection value decreases, as the cement  get to the discharge level, cement silo (cement) butterfly valve opens, and begin feeding. In the process of feeding, screw conveyor feeding rate before feeding until the cement on the arrival level.
