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.

種類我大概歸納了一下分為：法蘭球閥，內螺紋球閥，外螺紋球閥，硬密封球閥，軟密封球閥，全焊接球閥，對夾球閥，偏心半球閥，，進口球閥，三通球前期，高平臺

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

驅動方式：也就是我們怎樣把這個閥門開啟或關閉。通常以資源化利用和工程及用戶需要為前提，選用手動：手動分為手柄（徒手）操作和渦輪（杠桿的作用）操作，氣動：也就是現場有氣體源。電動：顧名思義就是有電就行，液動：由于液動是所有開啟方式成本相對較高的，一般都是現場需要實現快速開啟或關閉的時候才會選擇液動。耀圣經過多年總結一般液控蝶閥，液控球閥，液動快關抽汽止回閥，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.

使用介質：也就是接觸閥腔的流體是什么。如生活用水就只需要選用我們更普通的Q11F，Q41F，Q641F，Q941F等，如果是含纖維，泥沙，煤礦，高晶硅，石灰，水泥等，就需要用到耀圣生產的V型半球閥，氣動V型球閥，電動V型球閥了。

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.
