Ball valve product series Three-piece flange ball plug valve Shoulong ball valve Three-piece flange ball plug valve Introduction
Three-piece flange ball plug valve | Since ball valves usually use rubber nylon and polytetrafluoroethylene as valve seats Sealing ring material, so its service temperature is limited by the valve seat sealing ring material. The cut-off function of the ball valve is accomplished by the metal balls pressing against each other between the plastic valve seats under the action of the medium. The valve seat sealing ring undergoes elastic-plastic deformation in local areas under a certain contact pressure. This deformation can compensate for the manufacturing accuracy and surface roughness of the ball to ensure the sealing performance of the ball valve.
Since the seat sealing ring of the ball valve is usually made of plastic, the fire resistance and fire prevention of the ball valve should be considered when selecting the structure and performance of the ball valve, especially in petrochemical, metallurgical and other departments where equipment and pipes with flammable and explosive media are used. When using ball valves in pipeline systems, more attention should be paid to fire resistance and fire prevention.
