Electric Butterfly Valve
Structural Features And Uses
Metal seal butterfly valve series products are long-life, energy-saving butterfly valves. The products comply with the national standards JB/T8527-97 (metal seal butterfly valve), GB/T13927-92 (universal valve pressure test) standards and other related standards for valves. This product consists of valve body, butterfly plate, sealing ring, transmission mechanism and other main components. Its structure is designed using the three-dimensional eccentric principle, and a new processing technology compatible with elastic sealing and hard and soft multi-layer sealing enables the butterfly valve to reduce its torque force during operation, achieving labor-saving and energy-saving functions. This ensures the overall reliability of the butterfly valve in terms of corrosion resistance, high temperature resistance and wear resistance. This butterfly valve is suitable for use in food, medicine, petrochemical industry, power plants, steel plants, industrial environmental protection water treatment and high-rise buildings, as the best device to regulate flow and cut off fluids in water supply and drainage pipelines.
What is an explosion?
The prerequisite for causing an explosion is that explosive substances must be mixed with oxygen to a certain extent to cause a chemical reaction under appropriate ignition conditions. If the reaction speed exceeds the speed of sound, it is defined as an explosion. Explosive mixtures that have accumulated to a certain extent suddenly explode and cause destructive effects in the form of an explosion wave.
What is explosion proof?
If any one of the above three conditions is restricted from occurring, explosions can be prevented. In many use sites, the presence of explosive substances and oxygen is difficult to avoid, so ignition sources must be limited. Electrical equipment is a potential source of ignition, causing surface temperature to rise, electrostatic discharge or sparks caused by instantaneous current when the machine is running. Electrical equipment is designed to avoid excessive surface temperatures and sparks during operation. Therefore, flameproof electrical equipment does not become a potential source of ignition.
Main performance features
1. Unique structure, small and light, flexible operation, labor-saving and convenient;
2. The sealing is reliable and can achieve air sealing without leakage;
3. The flow characteristics tend to be linear with the best adjustment performance;
4. Using the three-eccentricity principle, the sealing surface has nearly zero wear and extends the service life of the valve;
5. Wide range of applications. For example: it can be used for water, steam, oil, air, gas and other media.
6. It is suitable for pipelines with different temperatures and pressure levels below 6.4MPa, and is resistant to corrosion and other media.
Performance Specifications
Product Advantages
Valve shaft valve plate octagonal connection
Experiments have proven that the octagonal connection can more effectively ensure the consistency of the valve shaft and valve plate movements, and reduce the failure rate by more than 20%.
Explosion-proof pin design
It adopts explosion-proof pin design
Valve seat embedded design
The valve seat has a backless design and light torque, making it convenient for users to replace the valve seat by themselves.
Self-lubricating design
The butterfly valve is designed with a self-lubricating ring with friction coefficient on the valve stem. It can greatly reduce the friction of valve opening and closing.
