Applicable operating temperature of butterfly valve
Butterfly valve is a commonly used flow control and regulating valve, widely used in fluid control systems in industrial production. The working temperature of a butterfly valve refers to the maximum temperature that the butterfly valve can withstand under normal operating conditions.The main Butterfly Valve product names of China Butterfly Valve Network include:Pneumatic Soft-sealed Flange Butterfly Valve,Pneumatic Ventilation Butterfly Valve,Pneumatic High Vacuum Butterfly Valve,Pneumatic Desulfurization Wafer Butterfly Valve,Pneumatic Desulfurization Flange Butterfly Valve,Quick-installed Sanitary Butterfly Valve,Rectangle Louver Regulate Butterfly Valve,Rotundity Louver Electric Regulate Butterfly Valve,Spring(Emergency Off) Quick Off Butterfly Valve
The working temperature of butterfly valves is affected by various factors, mainly including valve body materials, sealing materials, valve seat materials, etc. Different materials have different temperature resistance properties, so when selecting butterfly valves, it is necessary to make a reasonable choice based on the specific operating temperature.
Generally speaking, the working temperature range of butterfly valves is 196 ℃ to 1200 ℃. In low-temperature environments, butterfly valves need to choose materials suitable for low temperatures to ensure their normal operation. Common low-temperature materials include stainless steel, trifluoride, etc. These materials have good corrosion resistance and low temperature resistance at low temperatures.
In high-temperature environments, butterfly valves need to choose materials that can withstand high temperatures. Common high-temperature materials include high-temperature alloys, ceramics, duplex stainless steel, etc. These materials have high melting points and high temperature resistance, which can maintain the stability and sealing of valves at high temperatures.
The sealing material of butterfly valves is also one of the important factors affecting the working temperature. Common sealing materials include rubber, polytetrafluoroethylene, metal, etc. Different sealing materials have different temperature ranges, and it is necessary to choose the appropriate sealing material according to the actual situation.
In the selection and use of butterfly valves, the operating temperature of the butterfly valve needs to be determined based on the actual working conditions. On the one hand, it is necessary to consider the temperature of the fluid medium to ensure that the valve operates normally within the temperature range of the medium. On the other hand, it is also necessary to consider factors such as the pressure and flow rate of the medium to determine the pressure resistance and flow characteristics of the valve.
During the installation and maintenance of butterfly valves, attention should also be paid to the impact of operating temperature on the valve. In high temperature environments, the material of the valve may undergo thermal expansion and contraction, resulting in inflexible valve movement or inadequate sealing. Therefore, corresponding measures need to be taken, such as increasing the cooling device of the valve and using high-temperature resistant lubricants, to ensure the normal operation of the valve.
In general, the working temperature of a butterfly valve refers to the maximum temperature that the butterfly valve can withstand under normal operating conditions. When selecting and using butterfly valves, factors such as valve body materials and sealing materials need to be considered to determine the operating temperature range of the butterfly valve. Reasonably selecting the working temperature of butterfly valves can ensure the normal operation of valves and improve the efficiency and safety of fluid control systems.
