| 減壓閥是通過啟閉件對流體介質進行節流，將進口壓力降至某一個需要的出口壓力，并能在進口壓力及流量變動時，利用介質本身的能量保持不變的閥門。我廠新研制的新型減壓閥，采用新技術，在進口處加裝過濾網:耐壓、耐熱性能優良，產品適用于各種壓力、各種溫度的蒸汽、空氣和水介質的設備和管路上。 The redudng valve is the valve which can carry out the throttle to liquid media by open and close fittings, lower the inlet pressure to a needed discharge press,i.ue and keep un-charged by enert y of nedia when the inlet pressure and flux changes. The reducing valve newly developed by this plant adopts new technology and ecpai.p filter screen at the entrance place. The valve is featured with prt.ne resistance, heat resis-tance and good performance, which is used for the equipment and pipeline of steam, air and water media with various pres-sure and temperature. |
