摘要
对于负荷波动较大的蒸汽系统,减压阀的设计至关重要,不恰当的选型对设备安全与系统节能均会带来不利影响。先导式减压阀并联阀站对负荷变化适应能力强,可稳定可靠地保证供汽压力,消除蒸汽放散。在所述案例中,采用先导式减压阀并联阀站,取代原有的活塞式减压阀,解决了活塞式减压阀对负荷变化适应能力弱,无法静态减压,系统蒸汽放散,供汽不稳定等问题,为负荷波动较大场合下的蒸汽减压设计提供了新的思路。改造后设备运行稳定,安全可靠,颇有推广使用价值。
In the steam system which has the frequently fluctuated load, the design of the reducer is critical. Inappropriate lectotype will have the adverse effect on equipment safety as well as energy-saving. Piloted reducer parallel connection is adaptive to the change of the load, which can steady and ensure the pressure of the steam, eliminate steam emission. In this case, we use piloted reducer parallel connection instead of previous piston reducer which solve these problems of the weak adaptability of the load, unable to pressure reduction statically, steam emission of the system, unstable of steam supply. It provides the new idea of the design for steam reducer under the circumstance of frequent fluctuated load. The reconstructive equipment is able to operate steadily, safe and reliable which can be widely used.
