Description
技术领域 technical field
本实用新型涉及一种气体泄漏检测装置，具体的说，涉及了一种能够对输气管道接口法兰处的气体泄漏进行检测的管道气体泄漏检测装置。 The utility model relates to a gas leakage detection device, in particular to a pipeline gas leakage detection device capable of detecting gas leakage at the flange of the gas transmission pipeline interface.
背景技术 Background technique
在管道气体传输中，由于管道直径范围较大，在需要经常拆装的管段处和管道与设备相联接的地方，大都采用法兰联接。其密封效果主要是通过紧固螺栓使法兰垫片有足够的密封压从而阻止气体泄漏，实现密封。 In pipeline gas transmission, due to the large diameter range of the pipeline, flange connection is mostly used at the pipe section that needs to be disassembled frequently and where the pipeline is connected to the equipment. The sealing effect is mainly to make the flange gasket have sufficient sealing pressure by tightening the bolts to prevent gas leakage and achieve sealing.
在气体传输过程中，法兰的密封性会受到各种的影响，这些影响主要包括：法兰连接处的螺栓预紧力不足或不均；管道内压波动或管道下沉移动使连接螺栓受力变化；管道振动使连接螺栓松动；密封材料的耐压等级达不到规范要求；密封材料的老化导致垫片的回弹力下降；密封垫的结构选型不当。这些因素对管道法兰密封性能存在直接或间接的影响，特别是管道进气后，由于管道下沉、移动等因素影响，法兰连接处螺栓受力难免发生变化。如果不能及时检测到法兰渗漏问题并采取对应措施，在介质的冲刷下会使渗漏迅速扩大，造成各种损失。如果是有毒有害、易燃易爆的气体泄漏，还有可能造成人员中毒、火灾、爆炸等重大安全事故。 In the process of gas transmission, the sealing performance of the flange will be affected by various factors, which mainly include: insufficient or uneven pre-tightening force of the bolts at the flange connection; fluctuations in the internal pressure of the pipeline or the sinking movement of the pipeline, which will cause the connecting bolts to be affected. Force changes; pipeline vibration loosens the connecting bolts; the pressure rating of the sealing material does not meet the specification requirements; the aging of the sealing material leads to a decrease in the resilience of the gasket; the structure of the gasket is improperly selected. These factors have a direct or indirect impact on the sealing performance of the pipeline flange, especially after the pipeline is air-intake, due to factors such as pipeline sinking and movement, the stress on the bolts at the flange connection will inevitably change. If the flange leakage problem cannot be detected in time and corresponding measures are taken, the leakage will expand rapidly under the washing of the medium, causing various losses. If it is poisonous, harmful, flammable and explosive gas leakage, it may also cause major safety accidents such as personnel poisoning, fire, and explosion.
针对上述情况，由于现有的管道气体泄漏检测采用的是管道巡检，对微小泄漏点容易漏检，因此，需要采取更有效的检测方法和装置。 In view of the above situation, since the existing pipeline gas leakage detection adopts pipeline inspection, it is easy to miss detection of small leakage points. Therefore, it is necessary to adopt more effective detection methods and devices.
