手把手教你安裝和使用tescom調(diào)節(jié)閥
調(diào)節(jié)閥的安裝是應(yīng)該重點(diǎn)注意的問題,安裝質(zhì)量的好壞直接關(guān)系到調(diào)節(jié)閥的使用情況。安裝過程中應(yīng)注意以下哪些問題呢。

1調(diào)節(jié)閥在安裝之前,必須仔細(xì)地清除閥門在儲存期間所累積的塵土,在安裝過程中也要保持清潔。因?yàn)榛覊m會使閥座和內(nèi)件損壞。為了保持清潔,通常在當(dāng)天未焊的法蘭端部裝上蓋板。

2調(diào)節(jié)閥安裝時(shí),閥體上的箭頭應(yīng)與介質(zhì)流向一致。

3  調(diào)節(jié)閥是精密構(gòu)件,如果它們受到管道變形的力,將影響正常的工作。因此,法蘭與管道安裝應(yīng)垂直并且位置準(zhǔn)確避免管道的變形,并且,管道要適當(dāng)支撐一下,以防止它在閥門重量作用下發(fā)生彎曲和變形。  

4調(diào)節(jié)閥在與管道安裝時(shí)必須特別小心。若調(diào)節(jié)閥與管道焊接時(shí)不注意,未能消除應(yīng)力,則會產(chǎn)生變形的情況。焊接時(shí),必須嚴(yán)格避免焊渣飛入閥門內(nèi),焊渣的存在有損閥門的使用性能,如果焊渣直接濺在閥芯上,輕則直接影響調(diào)節(jié)閥的動(dòng)作,重則損壞閥芯與閥座。  

5管道在試壓和吹除時(shí),調(diào)節(jié)閥應(yīng)拆下,用相應(yīng)的直管段相連以防止焊渣等雜物卡在閥芯與閥座之間。拆下的調(diào)節(jié)閥開口法蘭端部應(yīng)用塑料布包扎牢固。

Hand in hand teaching you how to install and use regulating valves

The installation of the regulating valve is a key issue that should be paid attention to, and the quality of installation directly affects the use of the regulating valve. What are the following issues to pay attention to during the installation process.

Before installing the regulating valve, it is necessary to carefully remove the accumulated dust during storage and maintain cleanliness during installation. Because dust can damage the valve seat and internal components. To maintain cleanliness, a cover plate is usually installed at the end of the flange that has not been welded on the same day.

When installing the regulating valve, the arrow on the valve body should be aligned with the flow direction of the medium.

3 regulating valves are precision components, and if they are subjected to the force of pipeline deformation, it will affect their normal operation. Therefore, the flange and pipeline installation should be vertical and accurately positioned to avoid deformation of the pipeline, and the pipeline should be appropriately supported to prevent bending and deformation under the weight of the valve.
