| 摘 要： | 排气阀是长距离输水管道安全的重要防护设备。通过对比分析传统浮球式排气阀和气缸式恒速缓冲排气阀的,指出传统浮球式排气阀普遍存在的技术缺陷,认为气缸式恒速缓冲排气阀的结构更合理。工程实证研究结果表明,气缸式恒速缓冲排气阀对于管道水锤防护具有重要意义。

| Abstract: | The ex haust v alv e is an impor tant pro tect ive equipment for the safety of lo ng2distance water tr ansfer pipeline. Throug hthe com par ison and analy sis o f the st ructur es and mat hematical models of t raditio nal flo at2type exhaust v alv e and cylinder2t ypeex haust va lve w ith constant speed buffer, the tr aditional float2ty pe ex haust v alv e has technical defects and the st ructur e of cylin2der2ty pe ex haust v alve w ith constant speed buffer is mo re r easonable. Based on the eng ineer ing practice, the cylinder2type ex2haust valv e with co nstant speed buffer is important fo r the protection of pipeline w at er hammer. |
