There are thousands of types of valves that emit light and heat in various industries and industrial automation production. It plays a role in cutting off, regulating, stopping, checking, fast closing, fast opening, reducing pressure, reducing temperature, regulating pressure, temperature, insulation, slow opening, slow closing, explosion-proof, water discharge, feeding, flood prevention, etc. Among them, ball valves are the most widely used, penetrating into fields closely related to ordinary people, such as municipal administration, people's livelihood, real estate factories, etc. From nuclear power plants, hydropower stations, steel mills, petroleum, mining and other fields.

种类我大概归纳了一下分为：法兰球阀，内螺纹球阀，外螺纹球阀，硬密封球阀，软密封球阀，全焊接球阀，对夹球阀，偏心半球阀，，进口球阀，三通球前期，高平台

I have roughly summarized the types into: flange ball valve, internal thread ball valve, external thread ball valve, hard seal ball valve, soft seal ball valve, all welded ball valve, wafer ball valve, eccentric hemisphere valve, imported ball valve, three-way ball early stage, high platform

驱动方式：也就是我们怎样把这个阀门开启或关闭。通常以资源化利用和工程及用户需要为前提，选用手动：手动分为手柄（徒手）操作和涡轮（杠杆的作用）操作，气动：也就是现场有气体源。电动：顾名思义就是有电就行，液动：由于液动是所有开启方式成本相对较高的，一般都是现场需要实现快速开启或关闭的时候才会选择液动。耀圣经过多年总结一般液控蝶阀，液控球阀，液动快关抽汽止回阀，都是用在重要管道和重要部位的。

Drive method: That is how we open or close this valve. Usually, based on the premise of maximizing resource utilization and engineering and user needs, manual operation is selected: manual operation is divided into handle (bare hand) operation and turbine (lever function) operation, pneumatic: that is, there is a gas source on site. Electric: As the name suggests, it means that there is electricity, while hydraulic: Since hydraulic is a relatively high cost method for all opening methods, it is generally only selected when quick opening or closing is required on site. After years of summarization, Yaosheng has found that general hydraulic butterfly valves, hydraulic ball valves, and hydraulic quick closing extraction check valves are all used in important pipelines and parts.

使用介质：也就是接触阀腔的流体是什么。如生活用水就只需要选用我们更普通的Q11F，Q41F，Q641F，Q941F等，如果是含纤维，泥沙，煤矿，高晶硅，石灰，水泥等，就需要用到耀圣生产的V型半球阀，气动V型球阀，电动V型球阀了。

Using medium: what is the fluid that comes into contact with the valve chamber. For domestic water, we only need to use our most common Q11F, Q41F, Q641F, Q941F, etc. If it contains fiber, sediment, coal mine, high crystal silicon, lime, cement, etc., we need to use the V-shaped hemisphere valve, pneumatic V-shaped ball valve, and electric V-shaped ball valve produced by Yaosheng.
