Female threaded three pieces ball valve

Female threaded three pieces ball valve

Female threaded three-piece ball valve’s connection part uses female thread, or internal thread. The valve is assembled by three parts. Fully equal chamber provides a straight-through flow channel with little resistance for the medium. People usually believe that the most suitable usage of three piece ball valve is opening and closing directly, however, the recent development has been designed it for flow control.A thread is abbreviated by thread screw, which is a helical structure used to convert between rotational and linear movement. A thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter one called a tapered thread. Male and female, can be described as external and internal. For example, a screw has male threads, while its matching hole has female threads. This property is called gender.Internal and external threads illustrated using a common nut and bolt. The screw and nut pair can be used to convert torque into linear force. As the screw (or bolt) is rotated, the screw moves along its axis through the fixed nut, or the non-rotating nut moves along the lead-screw.
