(自由)進口浮球式蒸汽疏水閥 主要性能 Main performance

自由浮球式蒸汽疏水閥主要有浮球和自動排空氣裝置組成，利用高精度研磨不銹鋼空心浮球在閥腔內隨著凝結水的液位變化開啟或關閉閥門 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)進口浮球式蒸汽疏水閥 特點∶ Performance characteristics

閥腔內唯一的動作元件是不銹鋼空心浮球，采用高精度研磨工藝制造，整個球面均可做密封面，工作時無集中磨損，使用壽命長 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

閥腔內無易損件，浮球能根據水位變化而自由調節閥孔的開度，能夠連續排放凝結水，過冷度約等于5攝氏度，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

自動排空氣裝置分為兩種∶（低壓PN25以內）液囊熱敏元件組成和（過熱蒸汽系統）雙金屬片組成 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

不受壓力波動的影響，連續排水，噪聲小 Free from pressure fluctuation, continuous drainage, low noise

體積小，排量大，內置過濾器裝置。有水就排，能夠加快系統啟動速度 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

安裝示意圖 Installation diagram

請按閥體上流向箭頭所示安裝，注意疏水閥處于水平位置或低于設備出口，以保證正常疏水 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
