阀门是用于管理管道中流体输送的控制开关。拥有多种改变介质的方式，根据种类的不同，种类也不一样。可以说，阀门是一个大类，里面的种类很多。可用于控制水、蒸汽、油品、气体、泥浆、各种腐蚀性介质、液态金属和放射性流体等各种类型流体地流动，阀门的工作压力可以从0.0013MPa到1000MPa的超高压，工作温度可以c-270℃的超低温到1430℃的高温。下面小编来介绍一下阀门有着什么样的安装要求和注意的

Valves are control switches used to manage fluid transport in pipelines. There are multiple ways to change the medium, and the types vary depending on the type. It can be said that valves are a large category with many types. It can be used to control the flow of various types of fluids such as water, steam, oil, gas, mud, various corrosive media, liquid metals, and radioactive fluids. The working pressure of the valve can range from 0.0013MPa to 1000MPa under ultra-high pressure, and the working temperature can range from ultra-low temperature of c-270 ℃ to high temperature of 1430 ℃. Below, the editor will introduce the installation requirements and precautions for valves

一.阀门有着什么样的安装要求

1、 What are the installation requirements for valves

1、阀门安装之前，应仔细核对所用阀门的型号、规格是否与设计相符

1. Before installing the valve, carefully check whether the model and specifications of the valve used match the design

2、根据阀门的型号和出厂说明书检查对照该阀门可否在要求的条件下应用

2. According to the valve model and factory manual, check and compare whether the valve can be applied under the required conditions

3、阀门吊装时，绳索应绑在阀体与阀盖的法兰连接处，且勿拴在手轮或阀杆上，以免损坏阀杆与手轮

3. When lifting valves, the rope should be tied to the flange connection between the valve body and valve cover, and should not be tied to the handwheel or valve stem to avoid damaging the valve stem and handwheel

4、在水平管道上安装阀门时，阀杆应垂直向上，不允许阀杆向下安装

4. When installing valves on a horizontal pipeline, the valve stem should be vertically upwards and not allowed to be installed downwards

5、安装阀门时，不得采用生拉硬拽的强行对口连接方式，以免因受力不均，引起损坏

5. When installing valves, it is not allowed to use forceful and forceful connection methods to avoid damage caused by uneven force distribution

6、明杆闸阀不宜装在地下潮湿处，以免阀杆锈蚀。

6. Rising stem gate valves should not be installed in damp underground areas to prevent rusting of the valve stem.

2、 What are the installation precautions for valves

1、在安装阀门之前应清扫管道内的灰尘，焊渣等杂质

1. Before installing the valve, the dust, welding slag, and other impurities inside the pipeline should be cleaned up

2、管道连接标准与阀门连接标准相符，使用条件与阀门性能相符。

2. The pipeline connection standard is consistent with the valve connection standard, and the usage conditions are consistent with the valve performance.

3、阀门安装时应详细了解其性能及特点

3. When installing valves, it is important to have a detailed understanding of their performance and characteristics

4、阀门安装空间要保证使用方便，维护、修理简单。

4. The installation space of valves should ensure convenient use, simple maintenance and repair.

5、为避免螺丝、螺栓的松懈产生泄漏，使用前务必紧固每个螺丝

5. To avoid leakage caused by loose screws and bolts, be sure to tighten each screw before use

6、在使用过程中应注意阀门的介质，使用压力温度等，以免造成阀门的损坏

6. During use, attention should be paid to the medium of the valve, as well as the pressure and temperature used, to avoid damage to the valve

7、如阀门发生启闭失常，应查明原因，排除故障，不得用敲、砸等方法强行启闭。

7. If the valve experiences abnormal opening and closing, the cause should be identified, the fault should be eliminated, and methods such as knocking or smashing should not be used to forcibly open and close.

8、电、气动阀门在定货合同中无特出说明的只允许垂直安装在室内使用。

8. Electric and pneumatic valves are only allowed to be installed vertically indoors without special instructions in the order contract.

9、管道施工完毕后，应将管道线路上的阀门全部打开并残留的污物。

9. After the pipeline construction is completed, all valves on the pipeline should be opened and residual dirt should be removed.
