With the development of science and technology, the manufacturing process of butterfly valves has become more refined, and their applications have become increasingly widespread. What types of butterfly valves are there? What is the model number? A butterfly valve manufacturer will guide you through the types and model descriptions.
Butterfly Valve Manufacturer's Introduction to Butterfly Valve Types
1. According to the connection method: Butterfly valves can be divided into clamp-type, flanged, welded, threaded, and other types. (The commonly used connection methods are clamp-type butterfly valves and flanged butterfly valves.)
2. According to the actuation method: Butterfly valves can be divided into manual, turbine, pneumatic, electric, hydraulic, and solenoid valves. The common actuation methods are manual, turbine, pneumatic, and electric.
3. According to the sealing surface material: Butterfly valves can be divided into soft-seal butterfly valves and hard-seal butterfly valves. Soft-seal butterfly valves have better performance than hard-seal butterfly valves. Common sealing materials for soft-seal butterfly valves include EPDM, nitrile rubber, and PTFE. (Hard-seal butterfly valves are mainly used under high temperature and high pressure conditions.)
Manual butterfly valves are the most common type of butterfly valve, widely used in water conservancy projects, power plants, urban construction, petrochemicals, etc., and are commonly found in pipelines carrying weakly acidic or alkaline media such as fruit trees, steam, and oil. The importance of manual clamp butterfly valves to pipelines is self-evident. They are mainly used to cut or adjust the flow rate of circulating media in pipelines, ensuring normal pipeline operation and safe production conditions. For it to operate normally, in addition to paying attention to maintenance during operation, thorough preparation is also necessary during installation.
1. Before installation: Store it in a cool, dry, and ventilated environment. The valve must be sealed to prevent contamination by dust and debris;
2. The positions of the pipelines at both ends must not be misaligned. Otherwise, due to the inconsistent positions of the pipelines at both ends after valve installation, the valve body of the clamp butterfly valve may become strained or break;
3. Clean the valve and all installed pipelines again, ensuring that the inside of the valve and pipelines is completely clean and free of dust;
4. The installation position of the manual butterfly valve is also important. The valve installation position should facilitate personnel operation and future maintenance. It is proven that the installation position of a manual valve is approximately 1.2 meters. Valves outdoors should be covered to prevent damage from severe weather; 5. Ensure the butterfly plate is closed to prevent it from colliding with the pipe flange and affecting the sealing performance.
