摘要 针对大型灌溉管网中气液相间工况下现有进排气阀无法连续排气的问题,结合配压原理,提出了一种新型配压式进排气阀结构设计方案,阐述了其结构组成和工作原理;采用数值模拟分析与物理模型试验相结合的方法对不同阀瓣开度、不同排气压差条件下阀门的排气过程及排气量进行了研究,探明了阀瓣开度和排气压差对主阀腔体内部气流流态以及阀门排气量的影响,对比实测值与数模结果偏差为0.08%~6.43%,验证了分析方法的合理性;试验测得了DN50新型进排气阀各压差工况的最大排气量,结果显示,其排气量分别高于相关行业标准中规定的该尺寸进排气阀在排气压差为0.035 MPa和0.070 MPa时应达到的排气量要求达27.31%和21.71%,排气性能良好.

Abstract: In order to solve the problem of common air inbreathe-release valves cannot exhaust continuously under the condition of gas and liquid intervalin large-scale irrigation pipe networks, a new type of air inbreathe-release valvewith principle of pressure distribution was designed. The numerical simulation and physical modeling test were used to study on exhaust process and air displacement under the conditions of different valve openings and different exhaust pressure differences. The effects of valve opening degree and exhaust pressure difference on internal flow in the main valve cavity and valve exhaust volume was verified. The deviations of measured values and numerical results were between 0.08% and 6.43%, which verified the correctness of the numerical simulation.The physical test measured the maximum exhaust volume of new DN50 air inbreathe-release valve. The exhaust volumes of new air inbreathe-release valve exceed 27.31% and 21.71% which specified in the rela ted industry specifications when the exhaust pressure difference is 0.035 MPa and 0.070 MPa. Its exhaust performance is good.
