德國奧萊斯OLES進口高靈敏度減壓閥
【進口高靈敏度減壓閥】安裝說明:
1、減壓閥應安裝在便于操作和維修的地方,并且必須直立安裝在水平管路上,應注意使管路中介質的流向與閥體上箭頭所示方向*,切勿裝反。 2、高靈敏度減壓閥在安裝使用時,應先把旁通管路上的截止閥打開,排除管路中的冷凝水和汽水混合物,以防止減壓閥開啟時產生水擊現(xiàn)象損壞減壓閥,當無異常現(xiàn)象后,按順時針方向緩慢旋轉調節(jié)螺釘,將出口壓力調至所需要的壓力,調整好后,將鎖緊螺母背壓,擰上防護罩。 3、高靈敏度減壓閥應安裝過濾器,以防止介質中的雜質進入減壓閥,影響其性能。 4、安裝的減壓閥前后的一段直管,閥前直管長度為600mm,閥后直管長度為1000mm。
1. Pressure relief valves should be installed in places convenient for operation and maintenance, and must be installed upright in horizontal pipelines. Attention should be paid to making the flow direction of medium in pipelines consistent with the direction indicated by arrows on the valve body, and not reverse-loading. 2. When installing and using the high-sensitivity pressure relief valve, the cut-off valve in the bypass pipeline should be opened first, and the mixture of condensate water and steam water in the pipeline should be excluded to prevent the water hammer from damaging the pressure relief valve when the pressure relief valve is opened. When there is no abnormal phenomenon, the adjusting screw should be rotated slowly in clockwise direction to adjust the outlet pressure to the required level. After adjusting the pressure, the back pressure of the locking nut is tightened and the protective cover is screwed on. 3. High-sensitivity pressure relief valves should be equipped with filters to prevent impurities from entering the pressure relief valves and affecting their performance. 4. The length of the straight pipe before and after the installed pressure relief valve is 600 mm in front of the valve and 1000 mm in back of the valve.
【進口高靈敏度減壓閥】工作原理:
高靈敏度減壓閥屬于先導活塞式減壓閥,高靈敏度蒸汽減壓閥在普通減壓閥基礎上做了以下改進,加大了活塞面積,改變了節(jié)流結構,改變了密封形式,改進了導閥結構和調節(jié)彈簧形式,從而提高了產品的性能。由主閥和導閥兩部分組成。主閥主要由閥座、主閥盤、活塞、彈簧等零件組成。導閥主要由閥座、閥瓣、膜片、彈簧、調節(jié)彈簧等零件組成。通過調節(jié)調節(jié)彈簧壓力設定出口壓力、利用膜片傳感出口壓力變化,通過導閥啟閉驅動活塞調節(jié)主閥節(jié)流部位過流面積的大小,實現(xiàn)減壓穩(wěn)壓功能
