進口雙金屬片式疏水閥，Bimetallic steam trap，主要部件是雙金屬片感溫元件，隨蒸汽溫度升降受熱變形，推動閥心開關(guān)閥門。雙金屬片式疏水閥設(shè)有調(diào)整螺栓，可根據(jù)需要調(diào)節(jié)使用溫度，一般過冷度調(diào)整范圍低于飽和溫度15℃-30℃，背壓率大于70%，能排不凝結(jié)氣體，不怕凍，體積小，能抗水錘，耐高壓，任意位置都可安裝。雙金屬片有疲勞性，須要經(jīng)常調(diào)整，雙金屬片式疏水閥適用于散熱器、換熱器、夾套鍋、加熱盤管、烘干機、消毒器、層壓機等。
進口雙金屬片式疏水閥的四種性能：
1、排空氣和不：輸送管線的壓力或重力使閥打開，迅速排除空氣和水，縮短升溫時間。
2、阻汽：進入閥腔中的蒸汽使雙金屬元件彎曲產(chǎn)生熱拉力，并克服管道壓力是關(guān)閉閥球。熱拉力是隨相應(yīng)的飽和蒸汽曲線變化的。因此，在其壓力范圍內(nèi)都能有效地工作。
3、排放冷凝水：冷凝水逐步漸降低了雙金屬元件的熱拉力，使排放孔逐漸打開，冷凝水暢通*地排放。
4、起止回閥作用：閥球能在管線產(chǎn)生加流時，立即關(guān)閉排放孔，無須附加裝置。

德國托克TOK品牌：進口雙金屬片疏水閥特點及性能：
1、新型SCCV關(guān)閉系統(tǒng)設(shè)計，關(guān)閉可靠，壽命*。
2、排放溫度可調(diào)整，有效地利用高溫凝結(jié)水中的顯熱，節(jié)能*。
3、排放溫度在管網(wǎng)運行時就可進行，并可任意角度安裝。
4、閥前始終存有高溫凝結(jié)水，形成可靠的水封，無蒸汽泄漏。
5、抗水擊，排空氣性能優(yōu)良。 

6、動作時無噪音，有利于保護環(huán)境。
7、通汽初始，閥門全部開啟，低溫冷凝水和空氣迅速排除，大大縮短設(shè)備啟動時間。
8、內(nèi)部零件全部用不銹鋼制造，抗腐蝕、汽蝕。
可調(diào)雙金屬片溫度調(diào)整型蒸汽疏水閥用途：
用于蒸汽主管、分汽缸、蒸汽伴熱管線、散熱器、低溫加熱槽、夾屑鍋等。Adjustable temperature and adjustable bimetallic steam trap features and performance:
1, the new system design SCCV close, close, reliable, long life.
2, the discharge temperature adjustable, effective use of high-temperature condensation of the water was hot, energy-saving effect is remarkable.
3, the discharge temperature in the pipe network can be run, and installed at any angle.
4, the valve is always there before the high-temperature condensation of water to form a reliable seal, no steam leakage.
