Workers in Shanghai to open the valve is a professional valve manufacturer, main products are gate valve, ball valve, high pressure ball valves, etc., engineers Jieyou decades of professional experience, I will introduce today is the elastic ball air ball Valves:
Elastic sphere ball pneumatic valve is flexible. Ball and valve seat rings are metal materials, sealing pressure than the large, rely on the media itself can not seal the pressure has reached the requirements to be imposed by external forces. The valve for high temperature and pressure medium. Elastic sphere is open in the sphere of a flexible bottom wall slot, and access flexibility. When the closed channel, the wedge-shaped head with a stem to open up the ball and pressed to seal the valve seat. Release the ball before turning the wedge-shaped head, the ball followed to restore the original prototype, the sphere and the small gap between the valve seat, sealing surface can reduce friction and operating torque. Pneumatic valve position according to their channels can be divided into straight-through, three-and right-angle type. Distribution medium for the latter two ball and change the flow of media.
