進口德國蒸汽疏水閥 德國自由浮球式疏水器 德國鍋爐疏水閥德國威特TLK進口自由浮球式疏水閥
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。該疏水閥的結構比較簡單，主要由浮球和自動排空裝置組成。閥腔內唯一的動作元件——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 ; 閥腔內無易損件，可靠性高。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≈0℃，工作效率高。
自動排空裝置分為兩種 :（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。
Free-ball float trap
The drain valve is opened or closed by taking advantage of the change of liquid level of condensate water with the high-precision grinding stainless steel hollow float ball in the valve cavity. This steam trap has a simple structure, mainly consisting of float balls and automatic emptying devices. The sole action elements, namely, the stainless steel hollow float ball is manufactured by high-precision grinding process, and its entire sphere can serve as the sealing face and will not be worn intensively during the work, so it has a longer service life. In addition, there is no wearing part in the valve cavity, with a high reliability. The float ball can freely adjust the openness of the valve opening in response to the change of water level and discharge the condensate water continuously with a subcooled temperature of about 0℃ and higher efficiency.
The automatic emptying devices fall into two types : (within low pressure PN25) consisting of reservoir thermo-sensitive elements and (overheated steam system) consisting of bimetals.
優點：
1、唯一轉動的是高精度研磨的不銹鋼浮球，抗腐蝕。
2、結構簡單，維修方便。
3、不受壓力波動的影響，連續排水，噪聲小。
4、裝有自動排空裝置，能夠迅速排除空氣，防止氣堵和汽鎖。
5、體積小，排量大。
6、有水就排，能夠加快系統啟動速度。 |
