清潔要求
Cleaning requirements
經(jīng)常保持閥門外部和活動(dòng)部位的清潔,保護(hù)閥門油漆的完整。閥門上的灰塵用壓縮空氣吹掃,閥門上殘留的油和介質(zhì)用蒸汽吹掃干凈。疏水閥應(yīng)定期拆卸沖洗,防止堵塞。
Always keep the outside and moving parts of the valve clean and protect the integrity of the valve paint. The dust on the valve shall be purged with compressed air, and the residual oil and medium on the valve shall be purged with steam. The drain valve shall be dismantled and flushed regularly to prevent blockage.
定期潤滑
Regular lubrication
閥門梯形螺紋、螺母及嚙合部位和配合活動(dòng)部位,應(yīng)經(jīng)常保持良好的潤滑,防止銹蝕及卡死。露在外部的潤滑部位,如螺紋等應(yīng)注入二硫化鉬潤滑,既不污染灰塵,又能很好潤滑;對于旋塞閥等,應(yīng)定期加注潤滑油,防止磨損及泄漏。
The trapezoidal threads, nuts, engagement parts and mating moving parts of the valve should always be well lubricated to prevent rust and seizure. Molybdenum disulfide shall be injected into the exposed lubricating parts, such as threads, for lubrication, which will not pollute dust, but also provide good lubrication; For plug valves, etc., lubricating oil shall be filled regularly to prevent wear and leakage.
定期維護(hù)
Regular maintenance
閥體要完好,閥件應(yīng)齊全、完好,螺紋、螺母應(yīng)擰緊防止松動(dòng),填料壓件應(yīng)及時(shí)擰緊,缺失零件應(yīng)及時(shí)更換。補(bǔ)齊。此外,閥門不允許敲打、放置重物或站人,以免損壞閥門。
The valve body shall be intact, the valve parts shall be complete and intact, the threads and nuts shall be tightened to prevent loosening, the packing pressure parts shall be tightened in time, and the missing parts shall be replaced in time. Complete. In addition, it is not allowed to knock, place heavy objects or stand on the valve to avoid damaging the valve.
驅(qū)動(dòng)裝置靈活
Flexible driving device
驅(qū)動(dòng)裝置應(yīng)外面清潔;密封良好,密封部位應(yīng)嚴(yán)密無泄漏;傳動(dòng)部位應(yīng)定期潤滑,放置銹蝕或卡死;確保驅(qū)動(dòng)裝置工作正常自如,執(zhí)行操作準(zhǔn)確無誤。
The driving device shall be clean outside; The seal shall be good and the sealing part shall be tight without leakage; The transmission part shall be lubricated regularly to prevent rusting or jamming; Make sure that the driving device works normally and freely, and the operation is accurate.
閥門常見問題處理
Treatment of common problems of valves
在實(shí)際生產(chǎn)裝置中,一般閥門的泄漏情況有以下幾種情況:
In the actual production unit, the leakage of general valves can be classified as follows:
閥板變形所引起的介質(zhì)泄漏,呈滲流或小流量連續(xù)排放
The medium leakage caused by the deformation of the valve plate is continuously discharged in the form of seepage or small flow
閥體內(nèi)有雜物,關(guān)閉不嚴(yán)所引起的介質(zhì)泄漏,往往呈小流量泄漏
There are sundries in the valve body, and the medium leakage caused by untight closing is often small flow leakage
密封面操作造成密封不嚴(yán)所引起的介質(zhì)泄漏,往往呈滲漏狀泄漏
The medium leakage caused by loose sealing caused by the operation of sealing surface is often leaky
閥桿卡死致使閥門無法關(guān)閉所造成的介質(zhì)泄漏,這樣的泄漏往往在一定時(shí)間內(nèi)造成相當(dāng)程度的泄漏和污染
The medium leakage caused by the valve stem stuck and the valve could not be closed often causes considerable leakage and pollution within a certain period of time
密封填料不嚴(yán)密所造成的介質(zhì)泄漏,一般表現(xiàn)為滲漏,但量較小
The medium leakage caused by the loose sealing packing is generally manifested as leakage, but the amount is small
閥體有砂眼所造成的介質(zhì)泄漏,一般也是表現(xiàn)為滲漏,量較小
The medium leakage caused by sand holes in the valve body is also generally manifested as leakage, with a small amount
制造工藝上的問題所引起閥門泄漏,多為滲漏型。
The valve leakage caused by manufacturing process problems is mostly leakage type.
