當閥體和(hé)閥蓋有所洩漏時(shí),造成此現象的(de)原因有可(kě)能是:一天冷(lěng)凍裂造成的(de);二鑄鐵件鑄造質量不高(gāo),閥體和(hé)閥蓋體上有砂眼、松散組織、夾渣等缺陷從而造成洩漏;三當焊接不良,存在著(zhe)夾渣、未焊接,應力裂紋等缺陷時(shí)也(yě)有可(kě)能緻使其發生洩漏;四鑄鐵閥門被重物(wù)撞擊後被損壞也(yě)會造成閥體和(hé)閥蓋有所洩漏。

When the valve body and valve cover has been leaked, the cause of this phenomenon for two reasons may be: a day crack caused by freezing; two high-quality cast iron castings, valve bodies and valve covers have trachoma, a loose organization, slag, etc. defects resulting in leakage; three when welding bad, there is slag, no welding, stress cracks and other defects may also cause leakage of its occurrence; four cast iron valve damage after being hit by a heavy object can cause a valve body and valve cover the leak.

當發生以上幾種情況時(shí)我們要相應的(de)對(duì)其進行維護:1若是由于天氣原因造成的(de)我們可(kě)以對(duì)氣溫在0°和(hé)0°以下(xià)的(de)閥門,應進行保溫或拌熱(rè),停止使用(yòng)的(de)閥門應排除積水(shuǐ);2若是本身質量不合格的(de),我們更應該提高(gāo)鑄造質量,安裝前嚴格按規定進行強度試驗;3當面對(duì)焊接問題時(shí),應按有關焊接操作規程進行,焊後還(hái)應進行探傷和(hé)強度試驗;4對(duì)閥門上的(de)重物(wù)應禁止推放,絕對(duì)不可(kě)以用(yòng)手錘撞擊鑄鐵和(hé)非金屬閥門,大(dà)口徑閥門的(de)安裝應有支架。

When the above circumstances occur when we want to maintain them accordingly: 1 if the weather causes us right temperature of 0 ° and 0 ° below the valve, should be mixed with warm or hot, to stop using the valve water should be excluded; 2 if their quality unsatisfactory, we should improve the casting quality, pre-installation in strict accordance with the provisions of strength test; 3 When faced with welding problems, operational procedures should be carried out on welding, after welding, testing should be carried out and intensity of the test; 4 on the valve on the weights should not be allowed to push put absolutely no hand-hammer impact iron and non-metallic valves, large diameter of the valve should be installed bracket.
