英國(guó)斯派莎克DCV3止回閥中文版介紹：

DCV2和DCV3為碟片式法蘭對(duì)夾安裝止回閥，可廣泛應(yīng)用于過(guò)程管道、熱水系統(tǒng)、蒸汽和冷凝水等系統(tǒng)中的各種流體，連接尺寸符合EN558  Part1，Series49。

英國(guó)斯派莎克DCV3止回閥標(biāo)準(zhǔn)產(chǎn)品為金屬閥座，用于蒸汽系統(tǒng)。當(dāng)用于油、空氣、氣體和水系統(tǒng)時(shí)可以選用其他材料的閥座。

主：對(duì)夾式止回閥不適合用于有嚴(yán)重脈動(dòng)的場(chǎng)合，比如壓縮機(jī)。

   DCV系列止回閥結(jié)構(gòu)緊湊，安裝簡(jiǎn)便。可安裝在垂直或水平管道或傾斜管道，只需簡(jiǎn)單的兩片法蘭對(duì)夾安裝即可。

    DCV止回閥可用于蒸汽和各種液體、氣體等工業(yè)系統(tǒng)中，并可根據(jù)實(shí)際應(yīng)用提供各種選擇:

閥座選擇:

金屬閥座(Metal):-適用于蒸汽或其它高溫流體系統(tǒng)。

溫度范圍 -200℃~400℃。

橡膠閥座(Viton):-適用于油及氣體系統(tǒng)，可確保良好密封。

溫度范圍 -15℃~250℃。

三元乙丙閥座(EPDM):-適用于水系統(tǒng)。

溫度范圍 -50℃~150℃

彈簧選擇:

標(biāo)準(zhǔn)彈簧 - 用干蒸汽、水及其它多種工業(yè)流體系統(tǒng)中。

鎳鉻合金彈簧 - 用于高溫系統(tǒng)。

特強(qiáng)彈簧 - 用于鍋爐給水系統(tǒng)。

無(wú)彈簧 - 用于低流動(dòng)壓損系統(tǒng)。僅用于流向垂直向上的管道中。
