Butterfly Valve Structure, Advantages And Application Introduction
Butterfly valve is a kind of valve widely used in industrial fields, with simple design, compact structure, long service life and easy maintenance. This article by DELCO Valve for you to introduce the butterfly valve working principle, characteristics, as well as the structure and application.
Working principle of butterfly valve
When the valve stem rotates, it drives the butterfly plate to rotate. When the butterfly plate is parallel to the pipeline (i.e. rotated 90 degrees), the valve is completely open and the fluid can flow freely. When the butterfly plate is perpendicular to the pipe, the valve is closed and the fluid cannot pass through. In this way, the flow of fluid can be precisely controlled by the rotation of the control valve stem.
Basic Structure of Butterfly Valve
The main structural parts of butterfly valve include valve body, butterfly plate, valve stem, valve seat and sealing ring.
- Valve body: the valve body is the main part of the butterfly valve, some valve body is designed as a short cylinder, both ends are connected with the pipeline.
- Butterfly plate: the butterfly plate is located in the middle of the valve body, its shape is usually circular or nearly circular, driven by the valve stem through the center of the valve body.
- Stem: The stem runs through the valve body and the butterfly plate, and can be rotated to control the opening and closing of the butterfly plate.
- Sealing ring: The sealing ring surrounds the edge of the valve body or butterfly plate, when the butterfly plate is closed, the sealing ring ensures that there is no fluid leakage inside the valve body.
Advantages of butterfly valve
- Easy to open and close quickly, labor-saving, small fluid resistance, can be frequently operated;
- Simple structure, small external dimensions, short structural length, small size, light weight, suitable for large caliber valves;
- It can transport slurry and accumulate the least amount of liquid at the mouth of the pipeline;
- Under low pressure, can realize good sealing;
- Good regulating performance;
- Fully open when the valve seat channel effective flow area is larger, less fluid resistance;
- Opening and closing torque is small, because the rotating shaft on both sides of the butterfly plate by the media action is basically equal, and produce torque in the opposite direction, thus opening and closing more labor-saving;
- The sealing surface materials generally use rubber, plastic, so the low pressure sealing performance is good;
- Easy to install;
- The operation is flexible and labor-saving, can choose manual, electric, pneumatic, hydraulic mode.
Butterfly valve applications
- Chemical industry: butterfly valves are used to control the flow and direction of flow of various chemicals to ensure the smooth progress of the production process.
- Oil and gas field: effectively control the flow of oil and gas, to ensure the safe operation of the pipeline system
- Water treatment industry: butterfly valves are characterized by small flow resistance and flexible operation, and are an important part of the water treatment system.
- Food, pharmaceutical industry: butterfly valves are non-toxic, odorless, corrosion-resistant and easy to clean, which can ensure the hygiene and safety of food and drugs in the production process.
Conclusion
Butterfly valves have a wide range of application scenarios, covering a variety of industries. With the continuous progress of science and technology and the rapid development of industry, butterfly valve will show its superior performance and wide application prospects in more fields.
