进口双金属片式蒸汽疏水阀 美国RETZ瑞茨

　　RETZ工业/美国瑞茨，我们一直致力于流体控制和测控领域的持续创新，始于2005……(热静力)双金属片式疏水阀根据阀腔内温度的变化促使感温双金属片产生变形，从而驱使阀芯作往复位移启闭阀座孔，达到阻汽排水作用，用于铜管伴热线、蒸汽管线、小型蒸汽设备等(Thermostatic) imported bimetallic strip steam trap will deform the temperaturesensing Bimetal according to the temperature change in the valve chamber, so asto drive the valve core to reset and move the opening and closing valve seathole to achieve steam blocking and drainage, which is used for copper pipetracing line, steam pipeline, small steam equipment, etc

　　进口双金属片式疏水阀主要性能 Mainperformance

　　1∶顶针套内的顶针自由浮动，因此顶针能准确关闭在阀座的中心 The ejector pin in the ejector sleeve floatsfreely, so the ejector pin can be accurately closed in the center of the valveseat

　　2∶控制室内的弹簧和弹簧片吸收并减缓顶针进入阀座的动作（由蒸汽和蒸汽温度引起的） Thespring and spring plate in the control room absorb and slow down the action ofthe ejector pin entering the valve seat (caused by steam and steam temperature)

　　3∶顶针/阀座和顶针提升设计（处于关闭好而打开位置是的间距）能使顶针靠冷凝水的流动而关闭 Theejector pin / valve seat and ejector pin lifting design (the distance betweenthe closed position and the open position) can make the ejector pin close bythe flow of condensed water

　　4∶当设定的蒸汽疏水阀的温度接近饱和温度时，排放将是连续的，随着温度变低，排放变成间断性的，入口压力有助于排放循环间保持过度密封RETZ When the set temperature of the steam trap isclose to the saturation temperature, the discharge will be continuous. As thetemperature becomes lower, the discharge will become intermittent. The inletpressure helps to maintain the over sealing between the discharge cycles

　　进口双金属片式疏水阀性能特点∶Performance characteristics

　　在使用压力范围内不调整就可使用，低于饱和温度15℃左右自动排放高温凝结水 It can be usedwithout adjustment within the operating pressure range, and automaticallydischarges high-temperature condensate when it is about 15 ℃ lower than thesaturation temperature

　　负压状态阀关闭，起到止回阀作用 RETZThe negative pressure state valve is closed to function as a check valve

　　防冻、抗水击，排空气性能优良Antifreeze, water hammer resistance, excellent air exhaust performance

　　内部零部件全部采用特殊热处理工艺，抗腐蚀汽蚀 Allinternal parts adopt special heat treatment process to resist corrosion andcavitation

　　通汽初始，阀门全部开启，低温凝结水和空气迅速排出，缩短了设备启动时间 Atthe beginning of steam supply, all valves are opened, and low-temperaturecondensate and air are quickly discharged, which shortens the start-up time ofthe equipment
