電動球(qiu)閥(fa)主要(yao)是適用于(yu)氣(qi)體、石(shi)油(you)、空氣(qi)和水等介(jie)質中，由于(yu)電動球(qiu)閥(fa)的(de)優勢(shi)有很(hen)多(duo)，所以它(ta)的(de)使(shi)用范圍非常廣(guang)泛，那么下面就主要(yao)介(jie)紹一下電動球(qiu)閥(fa)的(de)優點吧(ba)。

主(zhu)要是(shi)適用于(yu)氣體、石油、空氣和(he)水等介質中(zhong)，由于(yu)電(dian)動球閥的(de)優勢(shi)有(you)很多，所以它的(de)使用范圍非常廣泛，那么下面就主(zhu)要介紹(shao)一下電(dian)動球閥的(de)優點吧(ba)。電(dian)動球閥主(zhu)要具備的(de)優勢(shi)是(shi)：

1、在(zai)較大地壓力(li)和溫(wen)度(du)范圍內(nei)，能實(shi)現完全密(mi)封；

2、工作介質在(zai)雙面上(shang)密封可靠；

3、能很好地承受來(lai)自管道的應力(li)；

4、可實現快(kuai)速啟(qi)閉；

5、球型關閉件(jian)能在位置(zhi)上(shang)自動定(ding)位。

電動(dong)球(qiu)閥的(de)維護包括(kuo)在(zai)安(an)裝前的(de)準備工作、氣(qi)動(dong)管路(lu)球(qiu)閥的(de)安(an)裝、氣(qi)動(dong)管路(lu)球(qiu)閥安(an)裝后的(de)檢查、氣(qi)動(dong)管路(lu)球(qiu)閥的(de)維修。

電動球閥在(zai)使(shi)用過(guo)(guo)程(cheng)中出現銹蝕現象。經過(guo)(guo)金相(xiang)組織分(fen)析、染色試(shi)臉、熱處理試(shi)臉、SEM等(deng)試(shi)驗(yan)分(fen)析，找到了材料(liao)銹蝕的(de)關鍵(jian)因素是因為材料(liao)中沿晶界的(de)碳化物析出形成(cheng)貧鉻(ge)區閥門、閘(zha)閥、截(jie)止閥、球閥，從而造成(cheng)

電動球(qiu)閥安裝完(wan)畢(bi)后，啟(qi)動氣(qi)(qi)動管(guan)路球(qiu)閥開、關數次，應該動作(zuo)(zuo)靈活，受力均勻，氣(qi)(qi)動管(guan)路球(qiu)閥工作(zuo)(zuo)正(zheng)常；根據管(guan)道壓力設(she)計要求(qiu)，通(tong)壓后檢測氣(qi)(qi)動管(guan)路球(qiu)閥與管(guan)道法蘭結合面的密封(feng)性能(neng)。
