Industrial valves are important accessories for controlling the flow of media on industrial pipelines. They can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The valve consists of three parts: valve body, opening and closing mechanism and valve cover.
1. Opening and closing function – cutting off or connecting the flow of fluid in the pipe;
2. Regulating function – regulating the flow rate and flow velocity in the pipe;
3. Throttling function – causing a large pressure drop after the fluid passes through the valve;
4. Other functions – a. Automatic opening and closing b. Maintaining a certain pressure c. Steam blocking and water drainage.
Valve Overview
The valve has a simple structure and reliable operation. It is used in pipelines with bidirectional flow media and has low fluid resistance and good sealing. Disadvantage: The medium is easy to leak from the valve stem.
TN is less than 150 degrees PN is less than 6.0 Mpa It has the advantages of simple structure, rapid opening and closing, easy operation, and small fluid resistance.
The butterfly valve has the advantages of simple structure, rapid opening and closing, small fluid resistance, and easy maintenance, but it cannot be used in high temperature and high pressure occasions, large-diameter water, steam, air, oil and other pipelines with PN less than 1.6Mpa and t less than 120℃.
The main features of forged steel valves include high temperature and high pressure resistance, reliable sealing, high strength, and long service life. Forged steel valves are suitable for high temperature and high pressure working conditions such as thermal power plants and oil and gas transportation. They can withstand high pressure and temperature and have excellent mechanical properties and impact resistance.
The advanced computer simulation analysis technology is adopted to analyze the stress, temperature, flow, and other parameters of the valves and their distributions, and evaluate the valve service performance under corresponding working conditions, optimize and address problems regarding valve application, thus protecting the product performance from the very beginning and maximize the value delivery to customers.
