產(chǎn)品名稱：雙金屬片式疏水閥

雙金屬片式疏水閥  BIMETALLIC TRAP   　　雙金屬片式疏水閥 　　雙金屬片式疏水閥的熱敏元件為兩種不同膨脹率的金屬通過特殊工藝壓鑄一起的雙金屬片，雙層金屬片在受熱后膨脹，由于不同的膨脹率使其產(chǎn)生的彎曲。利用這種特性制作成疏水閥的熱敏元件起到開關作用。雙金屬片式疏水閥分為不可在線調(diào)節(jié)（BK，CS17H和CS47）和可在線調(diào)節(jié)（可調(diào)雙金屬片式TB）。   Bimetallic Trap The thermo-sensitive element of bimetallic trap is a bimetallic element cast through a special process by two metals of different expansion ratio. When the bimetallic element expands after heated, different expansion ratio results in bending. The thermo-sensitive element produced on the basis of this quality can act as a switch. Bimetallic traps are divided into adjustable offline (BK，CS17H and CS47) and online (adjustable bimetallic element TB).   優(yōu)點： 1、結(jié)構(gòu)簡單，容易安裝和維修，抗水擊，排空性能優(yōu)越。 2、利用高溫凝結(jié)水形成水封，沒有新鮮蒸汽泄漏（零泄漏）。 3、動作靈敏，無噪聲。 4、抗水擊，對壓力突然變化沒有影響。 5、可用于過熱蒸汽系統(tǒng)。 6、可以使用高壓高溫的蒸汽管線。 7、具有良好的排空氣性能，不怕凍。   Merits 1.Simple structure, easy to install and maintain, resistant to water hammer and superb emptying performance. 2.Water seal by high-temperature condensate, no leakage of fresh steam (zero leakage). 3.Flexible and noiseless. 4.Water hammer resistance with no effect from abrupt pressure changes. 5.Adoptable for overheat steam system. 6.Adoptable for high-pressure and high-temperature steam pipes. 7.Good air discharge quality with resistance to coldness.   技術參數(shù)/Technique parameter 殼體壓力等級 Shell pressure grade 負荷泄漏率 Load leakage rate 使用介質(zhì) Used medium 允許背壓率 Permitted backpressure rate 節(jié)能效果 Energy saving effect 適用過熱蒸汽 Use superheated steam 1.6、2.5、4.0、6.4、10MPA 0% 蒸汽、凝結(jié)水 Steam、Condensate water 75% Excellence 適應 Adaption   工作壓差 Maximum operating pressure differential 抗凍性 Freezing resistance 排水方式 Drainage method 允許溫度 Maximum allowable temperature 排空氣裝置 Air exhaust system 抗水擊 Resist 10.0MPA Excellence 連續(xù)方式 Continue mode 420~550℃ 自動 Automatic 適應 Adaption
