閥門是用于管理管道中流體輸送的控制開關(guān)。擁有多種改變介質(zhì)的方式，根據(jù)種類的不同，種類也不一樣。可以說，閥門是一個大類，里面的種類很多。可用于控制水、蒸汽、油品、氣體、泥漿、各種腐蝕性介質(zhì)、液態(tài)金屬和放射性流體等各種類型流體地流動，閥門的工作壓力可以從0.0013MPa到1000MPa的超高壓，工作溫度可以c-270℃的超低溫到1430℃的高溫。下面小編來介紹一下閥門有著什么樣的安裝要求和注意的

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.閥門有著什么樣的安裝要求

1、 What are the installation requirements for valves

1、閥門安裝之前，應(yīng)仔細(xì)核對所用閥門的型號、規(guī)格是否與設(shè)計相符

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

2、根據(jù)閥門的型號和出廠說明書檢查對照該閥門可否在要求的條件下應(yīng)用

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

3、閥門吊裝時，繩索應(yīng)綁在閥體與閥蓋的法蘭連接處，且勿拴在手輪或閥桿上，以免損壞閥桿與手輪

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、在水平管道上安裝閥門時，閥桿應(yīng)垂直向上，不允許閥桿向下安裝

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

5、安裝閥門時，不得采用生拉硬拽的強行對口連接方式，以免因受力不均，引起損壞

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

6、明桿閘閥不宜裝在地下潮濕處，以免閥桿銹蝕。

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、在安裝閥門之前應(yīng)清掃管道內(nèi)的灰塵，焊渣等雜質(zhì)

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

2、管道連接標(biāo)準(zhǔn)與閥門連接標(biāo)準(zhǔn)相符，使用條件與閥門性能相符。

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

3、閥門安裝時應(yīng)詳細(xì)了解其性能及特點

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

4、閥門安裝空間要保證使用方便，維護(hù)、修理簡單。

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

5、為避免螺絲、螺栓的松懈產(chǎn)生泄漏，使用前務(wù)必緊固每個螺絲

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

6、在使用過程中應(yīng)注意閥門的介質(zhì)，使用壓力溫度等，以免造成閥門的損壞

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、如閥門發(fā)生啟閉失常，應(yīng)查明原因，排除故障，不得用敲、砸等方法強行啟閉。

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、電、氣動閥門在定貨合同中無特出說明的只允許垂直安裝在室內(nèi)使用。

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

9、管道施工完畢后，應(yīng)將管道線路上的閥門全部打開并清除殘留的污物。

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