What should be noted when using natural gas pipeline valves?

Product features of gas valves: 1. Elastic V-shaped polytetrafluoroethylene or nitrile rubber is used as the dynamic sealing filler; an initial seal is provided by a filler cover and stainless steel springs. The sealing performance of this filler improves as the medium pressure increases, giving it self-sealing capabilities and eliminating the need for manual maintenance. 2. When a fire breaks out outside the valve, the soft sealing material is burned by high temperatures, but the metal seal still ensures that the valve remains tightly sealed, thereby creating a dual-sealing structure of both soft and hard components, which results in excellent sealing performance. 3. Anti-static structure: When static electricity is generated due to rotational friction of the valve’s internal sealing element, a conductive device is used to establish a connection with the ground, thereby preventing static electricity from causing fires involving natural gas. 4. Fire-resistant structure: Even when the soft sealing material is burned out, the metal sealing surface can still maintain its sealing property, preventing the fire from spreading.
