Introduction and characteristics of ball valve

The main features of the ball valve are as follows: 1 The ball valve has low fluid resistance and has a flow resistance (actually zero) Ball valves generally have two structures of reduced diameter and non-reduced diameter channels. Regardless of the structure, the flow resistance coefficient of the ball valve is relatively small. Especially the so-called full-flow type, that is, the ball valve without reducing the diameter, because its channel diameter is equal to the inner diameter of the pipeline, the local resistance loss is only the frictional resistance of the pipeline of the same length, that is, among all the valves, this kind of ball valve has the smallest flow resistance. In the rocket launch and its test system, the resistance of the transmission pipeline is required to be as small as possible. There are two ways to reduce the resistance of the pipeline system: one is to reduce the fluid flow rate, for which it is necessary to increase the diameter of the pipe and the valve, which often has an adverse effect on the economy of the pipeline system, especially for low-temperature delivery system fluids. Hydrogen is unfavorable; one is to reduce the local resistance of the valve, so the ball valve naturally becomes the choice.
