The working principle of ball valve seal

     Ball valve sealing material pairing for the ball valve metal to metal.

    Classification

   1).One-way sealing: only in the direction of the valve seal sealinglabel direction.

   2).Two-way sealing: can be sealed in two directions.

    Structure form

    Structure of ball valve is divided into floating ball and fixed ball type,connection form for the flange connection, welding connection and screw connection.

     Working principle

      Hard seal ball valve, hard seal ball valve manual steel surface by spraying technology advanced, through the processing of different kinds of working conditions, maximum hardness up to HRC78. Theseal valve seat, maximum hardness up to HRC72. The matching grinding of ball and seat valve sealing surface, the sealing area areall precision ground. 

      Suitable for high temperature and high pressure water, steam, oil, coal, fiber, consistency and corrosive medium, and the medium with particles. Metal sealing ball valvefloating ball and fixed ball two structural metal seat ring and the spherical contact, spring load by acting in the seat ring even theseat ring and the spherical form a seal.

      Because the spring load so that the auxiliary sealing expansion, thesealing between the valve body and the valve seat. Spring loadenough to provide reliable seal between the valve seat and ball, on the condition of low pressure, the valve seat sealing surface and the sphere can be designed between the sealing grease injection system.
