Application Places and Characteristics of Butterfly Valves
As a Butterfly Valve Supplier, share with you. A butterfly valve is a valve that uses a disc-type opening and closing member to reciprocate about 90° to open, close and adjust the fluid channel. Today, the butterfly valve manufacturer will take you to understand the applicable places and characteristics of the butterfly valve. Let's learn about it with the editor.
"Where are the butterfly valves used?" "Butterfly valves are generally used for various water fluids, such as domestic water, fire water, process water, circulating water, chilled water, sewage, etc.. Butterfly valves can also be used for some powder materials. Butterfly valves cannot be used To adjust the flow rate. It can be used for automatic switching valves." "On official roads with large diameters, butterfly valves are generally used to control flow. For example, on DN1000 pipelines, if gate valves or stop valves are used, how big the valve should be Ah. But butterfly valves are rarely used to adjust the flow on small pipe diameters. One is not easy to adjust, and the other is poor sealing. Small diameter butterfly valves are generally used in water pipes, such as fire water, circulating water, etc. Also, it can be used in places where tightness is not required and frequent opening and closing. Of course, the cost of using butterfly valves on large-diameter pipelines is relatively low."
Butterfly Valve
"The two biggest characteristics of butterfly valves are: large diameter, low pressure difference. Compared with valves of other structures, butterfly valves are lighter in weight under the same diameter, simple in structure, small in size, and the larger the diameter, the more obvious the characteristics; the butterfly valve can adapt The pressure difference between the front and rear of the valve is smaller, and the technical requirements and manufacturing costs of the butterfly valve with the tighter sealing will increase."
The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0°-90°. When the rotation reaches 90°, the valve is in a fully open state. The butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be opened and closed quickly by rotating 90°, and the operation is simple. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics. The butterfly valve has two sealing types: elastic seal and metal seal. Elastic sealing valve, the sealing ring can be inlaid on the valve body or attached to the periphery of the butterfly plate.
