進(jìn)口自由浮球式蒸汽疏水閥

利用高精度研磨不銹鋼空心浮球在閥腔內(nèi)隨著凝結(jié)水的液位變化開啟或關(guān)閉閥門。該疏水閥的結(jié)構(gòu)比較簡(jiǎn)單，主要由浮球和自動(dòng)排空裝置組成。閥腔內(nèi)*的動(dòng)作元件——不銹鋼空心浮球，采用高精度研磨工藝制造，整個(gè)球面均可做密封面，工作時(shí)無集中磨損，使用壽命長(zhǎng) ; 閥腔內(nèi)無易損件，可靠性高。浮球能根據(jù)水位變化而自由調(diào)節(jié)閥孔的開度，能夠連續(xù)排放凝結(jié)水，過冷度≈0℃，工作效率高。

　　自動(dòng)排空裝置分為兩種 :（低壓PN25以內(nèi)）液囊熱敏元件組成和（過熱蒸汽系統(tǒng)）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(yōu)點(diǎn)：

1、*轉(zhuǎn)動(dòng)的是高精度研磨的不銹鋼浮球，抗腐蝕。

2、結(jié)構(gòu)簡(jiǎn)單，維修方便。

3、不受壓力波動(dòng)的影響，連續(xù)排水，噪聲小。

4、裝有自動(dòng)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(tǒng)啟動(dòng)速度。

Merits

1. The sole moving component is the high-precision grinding stainless float ball, which can resist erosion.

2. Its simple structure is convenient for maintenance.

3. To drain continuously with low noise, without being affected by the fluctuation of the pressure.

4. To be equipped with automatic emptying devices and it can eliminate air quickly and prevent air blocking and steam locking.

5. Small volume and large displacement.

6. To drain whenever there is water left over so as to quicken the startup speed of the system.
