Natural gas fireproof and anti-static ball valve is a pipeline control valve specially designed for flammable and explosive media such as natural gas, artificial coal to gas, liquefied gas, etc. It has special functions of fire prevention and anti-static to ensure safety during operation. Here are some key features and descriptions of this type of ball valve:
1. Fireproof design: The ball valve is designed with a dual sealing structure. When the soft sealing gasket melts due to high temperature, the valve core ball and the hard seal behind the soft seal will form a sealing relationship again, effectively preventing internal leakage and the spread of fire.
2. Anti static design: By installing conductive springs between the ball and the valve stem, as well as between the valve stem and the valve body, the static electricity generated during the valve opening process can be introduced into the ground through the static electricity channel, achieving the purpose of clearing static electricity and avoiding static electricity from igniting flammable media.
3. * * Material * *: The valve body, valve stem, and ball are usually made of stainless steel, such as 304 or 316, to ensure corrosion resistance and temperature resistance. The sealing surface material may use PTFE (polytetrafluoroethylene) or graphite to provide good sealing performance.
4. * * Operation mode * *: Ball valves can be equipped with various driving modes such as manual, worm gear drive, pneumatic, and electric (explosion-proof) to meet different operational needs.
5. * * Applicable medium * *: Suitable for liquefied gas, natural gas, steam, oil products, etc.
6. * * Applicable temperature * *: Generally within the range of -40 ∽+150 ℃, the specific temperature range depends on the choice of material.
7. * * Flange connection standards * *: Usually follow standards such as JB/T 79-94, GB9113-2000, etc.
8. * * Main external dimensions and connection dimensions * *: The size and connection dimensions of ball valves may vary depending on the nominal diameter (DN) to adapt to different pipeline systems.
9. * * Performance Specification * *: The nominal pressure PN may include 2.5, 4.0, etc., and the shell test pressure and high-pressure sealing test pressure may also vary accordingly.
10. * * Main component materials * *: The valve body and cover may be made of WCB/stainless steel, the valve stem and ball body may be made of stainless steel, the sealing surface may be made of stainless steel and polytetrafluoroethylene, and the packing may be made of polytetrafluoroethylene, etc.
