Problems solved by technology

This method has great limitations. On the one hand, the volume of the valve well is large, and the construction site does not have the ability to continuously supply the required water. On the other hand, it affects the safe and civilized construction on the site. The construction surface is not easy to clean and affects the subsequent construction procedures. The number of valve wells for refueling pipelines on the apron of large and medium-sized airports can reach dozens, which are far apart and located in different terrains inside and outside the flight area. The external environment also determines that this method is not universally applicable, so it is necessary to provide an apron refueling Pipeline valve well waterproof tightness detection device and detection method to solve the above problems

Abstract

The invention discloses an airport apron refueling pipeline valve well waterproof sealing performance detection device, and relates to the field of water prevention of valve wells. According to the airport apron refueling pipeline valve well waterproof sealing performance detection device, steel pipe sleeves are fixedly connected to the two sides of a valve well body in an inserted mode, oil conveying pipelines are fixedly installed in the steel pipe sleeves, chain type sealing rings are arranged in the opposite ends of the two sets of steel pipe sleeves, the chain type sealing rings are fixedly connected to the outer surfaces of the oil conveying pipelines in a sleeving mode; heat shrinkage sleeves are arranged on the outer surfaces of the opposite ends of the two sets of steel pipe sleeves, the heat shrinkage sleeves are fixedly connected to the outer surface of the oil conveying pipeline in a sleeving mode, and Z-shaped sealing rings are fixedly installed on the outer surfaces of the heat shrinkage sleeves. According to the airport apron refueling pipeline valve well waterproof sealing performance detection device and the detection method thereof, the waterproof performance of the valve well is effectively improved, and meanwhile, the waterproof performance of the valve well can be conveniently detected during installation.

Description

technical field [0001] The invention relates to the technical field of valve well waterproofing, in particular to a waterproof and tightness detection device and a detection method for a valve well of an apron refueling pipeline. Background technique [0002] At present, domestic aviation fuel engineering of large and medium-sized airports is equipped with an organic apron refueling pipeline system, that is, an underground aviation fuel pipeline network is laid from the airport oil depot to the apron, and the aircraft refueling work is completed through the refueling plug well on the apron ground, and the apron refueling pipelines are all buried The way of laying, the role of the valve well in the apron pipeline is very important. Because the pipeline is buried underground, the waterproof treatment of the valve well has always been a problem. According to statistics, more than 60% of the airport apron refueling pipeline valve wells have been used for a long time. Water seepa...
