| 减压阀是通过启闭件对流体介质进行节流，将进口压力降至某一个需要的出口压力，并能在进口压力及流量变动时，利用介质本身的能量保持不变的阀门。我厂新研制的新型减压阀，采用新技术，在进口处加装过滤网:耐压、耐热性能优良，产品适用于各种压力、各种温度的蒸汽、空气和水介质的设备和管路上。 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. |
