即便是關(guān)閉時間可達(dá)到3分鐘的“緩閉止回閥”相對系統(tǒng)來說都是速閉的。反之也相同，對某些系統(tǒng)而言較快關(guān)閉的止回閥可能卻是緩閉的。iI_Fbw8因此，一些好的工程師會估計出水錘的***次返回時間，如：長10公里的管線，管道材質(zhì)為鋼管，其波速大約為1000米/秒，因此***次水錘波返回時間則相應(yīng)地大約為：秒鐘，繼而規(guī)定緩閉止回閥的關(guān)閉時間可以設(shè)為23~25秒左右：如此關(guān)閉的止回閥可以阻止大部分返回流量對水泵的沖擊，同時將流速的改變降低，從而減少壓力的升高。某個南方的閥門廠的所謂“多功能水泵控制閥”在拷貝國外閥門的基礎(chǔ)上更加表現(xiàn)得討巧：在水泵停止后，立即由重力作用關(guān)閉70%的閥門，當(dāng)水流返回時，該流體會將剩余的30%關(guān)閉，而滯后的時間主要根據(jù)閥門的口徑而定，口徑越大則后段關(guān)閉時間就越長。但無論哪種假設(shè)與設(shè)計，都應(yīng)該與具體的工況分離來看，在沒有經(jīng)過計算的系統(tǒng)當(dāng)中，我們并不知道那多余的3~5秒或者30%的流量會不會有效降低壓力的升高，或者會不會造成對水泵的有害沖擊。因此同樣存在著不確定性，不加以選擇的斷然應(yīng)用與根本不采用是同樣不負(fù)責(zé)任的表現(xiàn)。zPVA6~|l_PRm4:三．“國際解釋”7aU*7!U***關(guān)于止回閥的特性與所謂“好與壞”的問題。宿州上海高特閥門哪里賣在不限制閘閥整體自由變形的情況下，與流體壓力相比，因熱產(chǎn)生的變形較大，而應(yīng)力較小。</p><div

鍍鋅板和鍍鋅鋼管防腐漆底材與鋼鐵材質(zhì)有很大的差別，鍍鋅板過于光滑，一般油漆很難附著在表面，即使干燥后也很容易脫落，無法達(dá)到防腐的作用。所以對于油漆的選擇一般是底漆配套面漆，底漆選用具有強附著力的雙組分環(huán)氧鋅黃底漆或者環(huán)氧富鋅底漆，面漆使用硬度較高的丙烯酸聚氨酯面漆或者氟碳面漆。鍍鋅板防腐漆施工方法如下： </p> <p> 底材處理：鍍鋅板表面非常光滑，也要采用打磨處理，使表面具有一定的粗糙度更有利于油漆粘附。 </p> <p> 底漆涂裝：環(huán)氧鋅黃底漆的甲乙組分按照5:1的比例混合，添加適量環(huán)氧稀釋劑，充分?jǐn)嚢杈鶆?，噴?遍，每遍間隔6小時以上，實干24小時。 </p> <p> 面漆涂裝：丙烯酸聚氨酯面漆甲乙組分按照5:1的比例混合，添加丙烯酸稀釋劑，充分?jǐn)嚢杈鶆?，噴?遍，每遍間隔6小時以上，實干24小時。 </p> <p> 施工驗收：施工完畢，漆膜光滑平整，顏色均勻。此時油漆中仍有殘余的溶劑尚未揮發(fā)，需要7天左右時間才能徹底干燥，達(dá)到理想的效果。 </p><p>
