Fire-proof and anti-static ball valve is a kind of pipeline that can be used for natural gas, artificial coal-to-gas liquefied gas, city gas and non-corrosive gas pipelines.
A conductive spring is arranged between the valve body and the valve body, so that the electrostatic energy generated during the opening process of the valve can be introduced into the ground through the set electrostatic channel into the pipeline to achieve the purpose of removing static electricity. Avoid electrostatic ignition to ignite flammable media to ensure system safety. The fire protection device, that is, the ball valve is designed with double seals. When the soft gasket is melted due to high temperature, the valve core ball is again designed with a right-angle hard seal behind the soft seal to form a sealing relationship again.
Compared with conventional ordinary ball valves, fire-proof and anti-static ball valves are widely used in many industries, and their safety performance is also improved a lot. For fire-prone occasions, it can effectively prevent internal leakage. The realization of this function mainly depends on the performance of the ball valve. Sealing ring, this kind of sealing ring belongs to double-layer seal, one layer of soft seal and one layer of metal seal. When the soft seal layer is destroyed by burning, the metal seal can further fill the void, playing a key alternate sealing role, and can To a certain extent, it can prevent a large amount of medium leakage and fire spread.
