As a fluid control device, the butterfly valve has the advantages of simple structure, small size, rapid opening and closing, and good diversion characteristics. It is widely used in various industrial occasions and civil facilities. The following is a brief introduction to the use, application scope and scenarios of butterfly valves:
1. Purpose
1. Fluid control: Butterfly valves are usually used to control the flow of gas and liquid, such as in water supply pipelines, chemical pipelines, drainage pipelines and refrigeration systems. Butterfly valves have the advantage of allowing flow to flow easily through the piping system during operation.
2. Anti-pollution: Butterfly valves can be used in water transmission pipelines of sewage treatment equipment, and can also be used in water supply and drainage systems in sewage processing. This valve has a simple structure, corrosion resistance, and is not easily affected by suspended solids in the fluid. and particle pollution.
3. Easy maintenance: The structure of the butterfly valve is simple, and it is convenient to disassemble and maintain. The valve can be removed by unscrewing the bolts at both ends. Butterfly valves can often be replaced and maintained without stopping production, which greatly reduces production downtime.
4. High safety: Butterfly valves are widely used in petroleum, chemical industry, water treatment, food industry and other fields at home and abroad, and have good safety and reliability in explosive and burning environments.
2. Application scope
1. Chemical industry and petroleum: In the production of chemical products and petroleum products, butterfly valves are usually used to control flow, with fast and flexible switching. The liquid is usually acid, alkali or solvent. In this case, it is necessary to choose corrosion-resistant materials.
2. Papermaking: In the papermaking industry, butterfly valves can be used to control flow and pressure, making the transmission of pulp more smooth, ensuring fast drying of paper and uniform surface quality of paper.
3. Food and pharmaceuticals: In food, beverage and pharmaceutical industries, fluid control is very important, because quality and safety assurance are essential in the production process, butterfly valves can ensure the hygiene and safety of raw materials and finished products in the production process.
4. Water treatment: In the process of water supply, drainage and chemical wastewater treatment, butterfly valves can play an important role. They can not only control the flow and pressure of water, but also help reduce leakage and pollution.
3. Scenario example
1. Water supply pipeline: In the water supply pipeline system of urban water plants, butterfly valves are used to control the water flow velocity and pressure, reduce energy loss, and make water flow more smoothly in the pipeline.
2. Thermal power generation: In coal-fired power plants and nuclear power plants, butterfly valves can be used to control the flow of medium water in the cooling cycle system to prevent pipeline blockage and slurry pump deformation.
3. Sewage treatment: In sewage treatment plants, butterfly valves can be used to control the flow and pressure of sewage to ensure the operation and stability of the system.
4. Pharmaceutical factory: In the pharmaceutical factory, the butterfly valve can be used to control the flow rate of the medium liquid, the pressure and temperature during the transmission process and other parameters, and provide flow control and safety guarantee during filling, sealing, offset and shutdown.
In short, the butterfly valve is a valve with a wide range of applications, a single function, and a huge impact. It is widely used in industrial production, public facilities, water treatment, and pharmaceutical manufacturing. Select the medium and working conditions in the scene to be specially identified to ensure the quality and correctness of the butterfly valve during manufacturing and installation.
