(自由)进口浮球式蒸汽疏水阀 主要性能 Main performance

自由浮球式蒸汽疏水阀主要有浮球和自动排空气装置组成，利用高精度研磨不锈钢空心浮球在阀腔内随着凝结水的液位变化开启或关闭阀门 RETZ free floating ball steam trap is mainly composed of a floating ball and an automatic air exhaust device. It uses a high-precision polished stainless steel hollow floating ball to open or close the valve according to the change of the condensate level in the valve chamber

(自由)进口浮球式蒸汽疏水阀 特点∶ Performance characteristics

阀腔内唯一的动作元件是不锈钢空心浮球，采用高精度研磨工艺制造，整个球面均可做密封面，工作时无集中磨损，使用寿命长 RETZ The only operating element in the valve chamber is a stainless steel hollow floating ball, which is manufactured by high-precision grinding process. The whole spherical surface can be used as a sealing surface, without concentrated wear during operation and with long service life

阀腔内无易损件，浮球能根据水位变化而自由调节阀孔的开度，能够连续排放凝结水，过冷度约等于5摄氏度，工作效率高 There are no wearing parts in the valve chamber. The float ball can freely adjust the opening of the valve hole according to the change of water level, and can continuously discharge condensate. The supercooling degree is about 5 degrees Celsius, and the working efficiency is high

自动排空气装置分为两种∶（低压PN25以内）液囊热敏元件组成和（过热蒸汽系统）双金属片组成 RETZ The automatic air exhaust device is divided into two types: (under low pressure PN25) composed of liquid bag thermistor and (superheated steam system) composed of bimetal

不受压力波动的影响，连续排水，噪声小 Free from pressure fluctuation, continuous drainage, low noise

体积小，排量大，内置过滤器装置。有水就排，能够加快系统启动速度 Small volume, large displacement, built-in filter device. Discharge water as soon as there is water, which can speed up the start-up of the system

安装示意图 Installation diagram

请按阀体上流向箭头所示安装，注意疏水阀处于水平位置或低于设备出口，以保证正常疏水 Please install as shown by the flow arrow on the valve body. Note that the drain valve is at the horizontal position or lower than the equipment outlet to ensure normal drainage
