Zhongding Valve (Jiangsu) Co., Ltd. specializes in stainless steel valve stainless steel "target=_blank> stainless steel ball valve generally has two structures of reduced diameter and no diameter reduction channel. Regardless of the structure, the flow resistance coefficient of the ball valve is relatively small. Especially the so-called The full-flow type, that is, the ball valve without shrinkage, because the passage diameter is equal to the inner diameter of the pipe, the local resistance loss is only the friction resistance of the pipe of the same length, that is, the flow resistance of the ball valve is the smallest among all the valves. In the system, the smaller the resistance of the pipeline is required, the better. There are two ways to reduce the resistance of the pipeline system: First, reduce the fluid flow rate, and increase the diameter of the pipe and the valve diameter, which is economical for the pipeline system. It often has adverse effects, especially for low temperature delivery systems (liquid hydrogen).
(1) Reduce the local resistance of the valve, therefore, the ball valve is naturally the best choice.
(2) The ball valve opening and closing switch is quick and convenient. Since the ball valve only needs to rotate the handle by 90° under normal conditions, the full opening or closing operation is completed, and the quick opening and closing is easy. It can realize fast opening and closing. The opening and closing time of some structures is only 0.05~0.1s, which can be used in the automation system of the test bench. When the valve is quickly opened and closed, the operation is free of impact.
(3) The ball valve has good sealing performance. The valve seat of most ball valves is made of elastic materials such as Teflon, and the sealing pair of metal and non-metal materials is usually called soft seal. In general, the sealing of the soft seal is easy to ensure, and the processing accuracy and surface roughness of the sealing surface are not very high.
(4) The ball valve has a long service life. Due to the good self-lubricating properties of PTFE, the friction and wear with the ball is small, and the roughness is reduced due to the improvement of the ball processing technology, thereby improving the service life of the ball valve.
