該閥是一個控制開關，用于管理管道中的流體傳輸。更換介質的方法有很多種，根據類型的不同，類型也不同。可以說，閥門是一大類，種類很多它可以用來控制各種流體的流動，如水、蒸汽、石油產品、氣體、泥漿、各種腐蝕性介質、液態金屬和放射性流體。
The valve is a control switch used to manage the flow of fluid in the pipeline. There are many ways to change the medium, depending on the type, the type is also different. It can be said that the valve is a large category, there are many kinds of it can be used to control the flow of various fluids, such as water, steam, petroleum products, gas, mud, various corrosive media, liquid metal and radioactive fluid.
良工閥門的工作壓力范圍為0.0013mpa~1000MPa，工作溫度范圍為c-270~1430℃。閥門的安裝要求和注意事項是什么
The working pressure range of the valve is 0.0013 MPA ~ 1000 MPA, and the working temperature range is c-270 ~ 1430 °C. What are the installation requirements and precautions for valves

1、閥門的安裝要求是什么
1. What are the installation requirements of the Valve 

2、安裝閥門前，仔細檢查所用閥門的型號和規格是否與設計相符
2. Before installing the valve, check carefully whether the type and specification of the valve used are in conformity with the design 

3、根據閥門型號和出廠說明書，檢查閥門是否能在要求的條件下使用
3. According to the valve type and the factory manual, check whether the valve can be used under the required conditions. 

4、起吊閥門時，繩索應系在閥體與閥蓋之間的法蘭連接處，不得系在手輪或閥桿上，以免損壞閥桿和手輪
4. When lifting the valve, the rope should be tied to the flange joint between the valve body and the valve cover, not tied to the handwheel or the valve stem, in order not to damage the valve stem and Handwheel 

5、在水平管道上安裝閥門時，閥桿應垂直向上，閥桿不允許向下安裝
5, in the Horizontal Pipeline Installation Valve, the valve stem should be vertical up, the valve stem does not allow to install 

6、安裝良工閥門時，不允許采用硬拉的強制對口連接方式，以免因應力不均勻而損壞
6, installation of good valve, do not allow the use of hard-pull forced counterpart connection, avoid Uneven stress and damage 

7、明桿閘閥不應安裝在地下潮濕的地方，以避免閥桿腐蝕。
7, Stem Gate Valve should not be installed in the underground moist place, to avoid stem corrosion.
