Difference between fireproof and antistatic ball valve and ordinary ball valve
Ha ha, that is, non sparking metal, alloy, copper, alloy, aluminum is all right
Therefore, the general manufacturers will be made fire-resistant, anti-static.I do the valve above all hand typing, and if the answer is satisfactory, please adopt in good time Oh. There are questions to ask!!!
Fire valve is generally aimed at soft sealing material valve, that is, after the fire on the valve, the ball valve can rely on medium force and metal valve seat (body) contact, to achieve sealing, so that the fire does not go down the pipeline. Anti-static valve is for soft sealing material of the valve, when the ball switch and soft seal friction, will produce static electricity, if the pipe is taking the flammable and explosive medium is very dangerous, so the valve will set a device outside the sphere will Unicom electrostatic oriented, to prevent static electricity.Generally like the market valve, a little better quality, they are the default valve is fire, anti-static, the production costs of these two types of valves is bad, at most two or three dollars, which is still much.
