自闭式煤气排水器工作管关键结构参数设计方法

Design of Key Structural Parameters about Self-closing Gas Drainage Pipe

在大量现场试验和理论研究的基础上,结合煤气排水器的结构特点和工作原理,提出了一种煤气排水器工作管关键结构参数设计方法,可实现对低压室内封闭用结构部分可承受压力的计算;同时根据约束条件自动计算其余各腔室的应设计数量和相应工作管长度。通过以上方法有效地保证了排水器的实际可承受压力与设计相同,防止泄漏或密封频繁开闭。

On the basis of large number of field test and theoretical analysis, combining with the gas drainage pipe＇s structure characteristics and working principle, this paper puts forward a design method of key structure parameters about the work tube of gas drainage, to calculate the bearing capacity of the low-pressure chamber, as well as the number of other chambers and the corresponding work tube length according to the constraint condition. Using the above method could effectively guarantee the actual pressure of the drainer is accordance with the design value, to prevent from leakage or seal open and close frequently.
