In a threaded gate valve,the thread’s lead is the linear distance the screw travels in one revolution results in the advantage of the thread. In most applications, in order that friction is sufficient to prevent linear motion being converted to rotary, the lead of a thread is chosen. This characteristic is essential to the vast majority of its uses. The tightening of a fastener's screw thread is comparable to driving a wedge into a gap until it sticks fast through friction and slight plastic deformation.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.
A threaded gate valve has a thread on it to connnect different parts of valve.A thread is also called thread screw. It 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.
