A Flanged Globe Valve is a common type of valve used to control the flow of fluids and to cut off fluids. It is composed of a valve body, a valve cover, a valve disc and a flange. The following are some features of flanged globe valves:
1. Structural design: Flanged globe valves usually adopt straight-through structure, that is, the fluid flows in a straight line in the valve body. The valve disc is placed vertically with the seat and the valve disc is raised or lowered to control the flow switch. 2. Flange connection: Both ends of the flanged globe valve are equipped with flanges for connection with the pipeline system. Flanges are usually bolted so that the valve is firmly connected to the piping system. 3. Valve disc and seat: Valve disc is a key part of the valve, it forms a seal between the valve seat and control the flow of fluid. The valve disc is generally spherical or disk shape, and different shapes and materials are selected according to the fluid characteristics and working conditions. 4. Operation mode: Flanged globe valve can be manually operated, electric actuator or pneumatic actuator to control the valve switch. You can select different operation modes according to the actual requirements. Flanged globe valves are suitable for the control of various media, such as liquid, gas and steam. They are widely used in petroleum, chemical, electric power, metallurgy, pharmaceutical and other industrial fields to control the flow and cut-off of fluids.
Compared with other types of valves, flanged globe valves have the characteristics of simple structure, reliable use and good sealing. They can operate under high temperature, high pressure and corrosive media conditions, and can achieve accurate flow regulation and truncation. When it comes to flanged globe valves, there are some other aspects to consider:
1. Material selection: The material selection of flange globe valve depends on the nature of the medium and working condition requirements. Common materials include carbon steel, stainless steel, alloy steel, etc. For corrosive media, corrosion resistant materials such as 316 stainless steel can be selected. 2. Flange standards: Flanged globe valve flanges usually meet international standards, such as ANSI, DIN, JIS, etc. Selecting the appropriate flange standard ensures valve compatibility with the piping system. 3. Sealing performance: The sealing performance of the flange globe valve is crucial to the working effect of the valve. Common sealing forms include metal sealing and soft sealing. Metal seals are suitable for high temperature and high pressure environments, while soft seals are suitable for low temperature and general conditions. 4. Operation mode: Flanged globe valve can be manually operated, electric actuator or pneumatic actuator to control the valve switch. According to the actual needs and degree of automation, choose the appropriate mode of operation. 5. Maintenance and maintenance: Regular maintenance and maintenance of the flange globe valve can ensure its good working condition and life. This includes cleaning the inside of the valve, checking for disc and seat wear, and regularly lubricating the moving parts of the valve.
In general, flanged globe valves are a common and important type of valve used to control the flow and cut-off of fluids. Through reasonable material selection, sealing performance and operation mode, it can meet the needs of fluid control under different working conditions. Regular maintenance and maintenance can ensure the normal operation of the valve and extend the service life.
